ITT IDEAL COLOR 1960 ST OSCAR 8 YEAR 1978.

THE  ITT IDEAL COLOR 1960 ST OSCAR 8    is A 17 (42Cm) Inches color television in a portable  cabinet with 8 programs with manual potentiometric channel tuning preselection system and ultrasonic remote control program change called ideal computer.. The set has even a manual sensor buttons programs change.

This invention relates to a remote television control, and more particularly, to a channel-changing control which responds to acoustical signals emitted from a remote location.
Conventional remote control systems for television sets are normally wired into the sets. Usually, it is not feasible to retrofit existing television sets not having a remote control capability with conventional remote control systems.

 Where such apparatus as television receivers are to be controlled from a viewer location as to channel, volume, brightness, etc., the remote control systems usually are made up of a hand held transmitter which transmits an ultrasonic signal to a receiver connected to or built within the television receiver. The depression of buttons on the transmitter causes a variety of signals or signal frequencies to be transmitted, whereby channel change, volume change, etc. is responsively obtained.
However such systems have individually suffered from one or more problems, such as inability to have direct access to the desired channel, slow access, insufficient noise immunity making it often possible to operate the system with the jingling of a key chain or an ultrasonic sound originating from a dishwasher etc., unreliable control due to the absence of means to detect and suppress transmission errors resulting from echoes, interfering signal sources, etc. Also some control systems are not suitable for continuous analog commands such as volume, brightness, etc. Existing systems also often require the need for bandpass filters and accurate crystal oscillators which make them costly. Many systems are not very suitable for integration into custom integrated circuits. 

The present invention provides a remote control system whereby the nature of the remote control signal allows utmost reliability of control. The remote control receiver will be found to be virtually immune to echoes and ambient ultrasonic noises, and therefore will not produce a false response in the presence of echoes and ultrasonic interfering signals. A variety of kinds of commands can be provided, and with the preferred embodiment disclosed, up to ninety-nine channels in a television receiver can be instantaneously selected, without the requirement for sequentially stepping through each channel. Volume can be varied or muted, tint or brightness controlled, etc.
The above advantages are obtained by the transmission of a unique type of two tone coded signal which advantageously contains information defining start-up transmitted data, type of command (i.e. channel select identification or miscellaneous command such as volume), information permitting reconstruction of clock and identification of end of data. The two tones are transmitted sequentially. The second tone is transmitted to provide masking of echoes produced by the first tone and to mask noises that may be present in the operating environment of the system.
Since the two tones may be close together in frequency, it is possible to operate the remote control system in conjunction with high sensitivity resonant type microphones, thereby achieving high sensitivity together with high noise immunity. This also eliminates the need for input bandpass amplifiers.
The inventive receiver is thus rendered immune from operation by extraneous noise further by the provision of received data error checking circuitry for the timing of input pulses, etc., and for rejecting the data if an error is detected. The receiver also has provision for operation of continuous analog circuits in a television set, such as brightness, volume and tint controls, etc. Since echoes are masked out in the present system, data transmission can occur much more rapidly than in prior systems, as the receiver does not have to wait until echoes die out between transmission of bits for identification of data pulses.
Since all that is frequency dependent is the detection of signal above or below a predetermined reference frequency, accurate crystals for timing and reference frequency generation are not needed. The receiver is virtually entirely digital logic, making it suitable for monolithic integration with a minimum of external components. CMOS integrated circuit logic is preferred, minimizing power supply requirements.
In the preferred embodiment, two digits are transmitted separately and the second must be received within a given time interval, or the first number is disregarded. This method eliminates the need for a clear key as normally present on calculators.
The output of the receiver is a binary or BCD signal which can be used by known means to control the frequency of a selected channel, or to perform other functions such as variation of volume, control of brightness, tint, etc. in a television set.

• It has a  sensor keyboard for local commands, includes a plurality of tuning positions each defined by an adjustable potentiometer, a neon bulb indicator, a UHF/VHF switch and a two pole momentary contact touch switch. A common tuning capacitor has a tuning voltage developed thereacross for controlling the tuning of a varactor diode tuner. A source of reference potential is coupled across the tuning potentiometers and closure of any touch switch results in the tuning capacitor being charged from the voltage reference source through the selected one of the tuning potentiometers. The neon bulbs yield a visual indication of the selected tuning position. Circuitry for automatically placing control of the tuner to a preselected one of the tuning positions upon turn on of the receiver is also included.

It's a Circuit arrangement for establishing a reference potential of a chassis of an electrical device such as a radio and/or TV receiver, such device being provided with at least one contactless touching switch operating under the AC voltage principle. The device is switched by touching a unipole touching field in a contactless manner so as to establish connection to a grounded network pole. The circuit arrangement includes in combination an electronic blocking switch and a unidirectional rectifier which separates such switch from the network during the blocking phase.In electronic devices, for example TV and radio receivers, there are used in ever increasing numbers electronic touching switches for switching and adjusting the functions of the device. In one known embodiment of this type of touching switch, which operates on a DC voltage principle, the function of the electronic device, is contactlessly switched by touching a unipole touching field, the switching being carried out by means of an alternating current voltage.

•   It has Potentiometric manual tuning search for each program.

  Manual setting for basic values of: brightness, contrast, color, volume

The mechanical turret approach to television tuning has been used almost exclusively for the past 60 years. Even though replete with the inherent disadvantages of mechanical complexity, unreliability and cost, such apparatus has been technically capable of performing its intended function and as a result the consumer has had to bear the burdens associated with the device. However, with the " recent " Broadcast demands for parity of tuning for UHF and VHF channels, the increasing number of UHF and cable TV stations have imposed new tuning performance requirements which severely tax the capability of the mechanical turret tuner. Consequently, attempts are now being made to provide all electronic tuning to meet the new requirements.

The invention relates to a tuning unit with bandswitch for high frequency receivers, especially radio and television receivers, having a potentiometer system for the control of capacity diodes, the said potentiometer system consisting of a plurality of parallel resistance paths along which wiper contacts can be driven by means of screw spindles disposed adjacent one another in a common insulating material housing in which a bandswitch formed of metal rods is associated with each tuning spindle.

In these tuning units, the working voltages of the capacity diodes in the tuning circuits are recorded once a precise tuning to the desired frequency has been performed. A potentiometer tuning system has great advantages over the formerly used channel selectors operating with mechanically adjustable capacitors (tuning condensers) or mechanically adjustable inductances (variometers), mainly because it is not required to have such great precision in its tuning mechanism.

Tuning units with bandswitches formed of variable resistances and combined with interlocking pushbuttons controlling the supply of recorded working voltages to capacity diodes are known. Channel selection is accomplished by depressing the knobs, and the tuning or fine tuning are performed by turning the knobs. The resistances serving as voltage dividers in these tuning units are combined into a component unit such that they are in the form of a ladderlike pattern on a common insulating plate forming the cover of the housing in which the tuning spindles and wiper contacts corresponding to the variable resistances are housed. The number of resistances corresponds to the number of channels or frequencies which are to be recorded. The wiper contact picks up a voltage which, when applied to the capacity diodes determines their capacitance and hence the frequency of the corresponding oscillating circuit. The adjustment of the wipers is performed by turning the tuning spindle coupled to the tuning knob. By the depression of a button the electrical connection between a contact rod and a tuning spindle is brought about and thus the selected voltage is applied to the capacity diodes. Since the push buttons release one another, it is possible simply by depressing another button to tune to a different receiving frequency or a different channel, as the case may be.

For many years, mechanical turret tuners have been commonly employed in television receivers to select the VHF channels and a second rotary or continuous tuner has been used to select the UHF channels. For most television receivers, this requires two different channel selection knobs; and the tuners themselves are relatively bulky and require a relatively large amount of space within the television receiver cabinet. Because of the nature of these tuners, it also is necessary to locate them directly behind the front level panel of the receiver, which imposes significant restrictions on the cabinet design and the arrangement of parts within the cabinet, reducing the flexibility of design which would be possible if such tuners could be eliminated.

Some mechanical tuners are equipped with programmable switches to permit them to be used to select either a UHF or a VHF channel at a tuner position by programming the tuner for the local area where the television receiver is to be used. The disadvantages of the cumbersome mechanical tuners, however, are not overcome. Instead, the tuner is made even more complicated by such an arrangement.

It is desirable, and in the U.S./Europe it was  necessary, to effect selection of the UHF and VHF channels in a comparable manner. When such tuning compatibility is imposed, significant problems are encountered in providing a mechanical turret-type tuner having detented positions for all of the possible UHF channels which must be accommodated for television receivers capable of operating in any given locality in which the receiver is capable of receiving transmitted television signals. UHF turret tuners with detent tuning selection for each of the 70 possible UHF channels are difficult and expensive to manufacture, and even the display of all of the UHF channel numbers in a manner which is compatible with the display for the much smaller number of VHF channels is difficult to accomplish.
The introduction of voltage-variable capacitor or varactor tuners for the VHF and UHF bands to which a television receiver can be tuned has opened the way for electronic tuning of television receivers. This replaces the cumbersome mechanical turret tuners and allows greater flexibility in the design of the channel selection panel and in the location of tuner parts within the receiver cabinet. Even so, if the receiver is to be made capable of individual selection of any one of the 70 UHF channels in addition to the VHF channels, it has been necessary to provide a large number of individual tuning components. For example, in many prior art electronic tuner control circuits, it has been necessary to provide a separate tuning potentiometer for each of the 70 UHF channels if full capability of UHF channel selection is desired. This results in a relatively expensive tuner configuration requiring a large number of parts.

• The tuning has a manual AFC red button to deactivate it during search.(the green button picured)
  

 The general concept of Automatic Frequency Control (AFC) for television receivers is known in the art and has been adapted to radio receivers as well as to television receivers of both the monochrome and color variety. The general purpose of such a system is to assist the user in attaining proper fine-tuning of the receiver without requiring critical manual adjustment. The advantage of such a system is self-evident but its value to a color receiver is markedly increased due to the fact that improper tuning of a color receiver manifests itself in incorrect colors, or even a total lack of color, in the reproduced image.
 Typically, the AFC system is tuned to a reference or center frequency corresponding to the desired video IF frequency and so long as the tuning is reasonably close, within the response of the AFC system, an error voltage is developed to correct the tuning. If the user of the television receiver makes the fine-tuning adjustment while the AFC system is operative, he may adjust it to a point where the picture is acceptable but a substantial amount of AFC correction voltage is required. Thus, the receiver may be tuned at the limit of the "hold-in" range and would not give the proper "pull-in" performance when the channel selector is switched to the next channel. Accordingly, it is desirable to include an AFC defeat circuit for disabling the AFC system during manual fine-tuning. Heretofore, most AFC defeat circuits have required that the user of the television receiver defeat the AFC system by means of a manual switch. It is apparent, however, that the typical user of a television receiver may at times forget to flip the switch and hence the attendant problems are realized.
 Moreover, using this arrangement, the only indication--during adjustment--of which channel is selected is by station identification.

 

• The set has a uncommon SHUT-OFF feature remotely controlled.

In conventional television receivers, a manually operated ON-OFF power switch is used to turn on or turn off the television receiver, so that when the television receiver is once turned on, it remains in the reception mode even after the transmission of television programs has been terminated.

The user normally pressing the off button on the remote brings  in a st-by state and that  In conventional television receivers.

Therefore, power is wasted. To overcome this problem, there has been proposed a method of using a mechanical relay  so as to supply or interrupt the power to a television receiver like pressing the mechanical switch on the front of the set.

To re - power up the set the  mechanical switch on the front of the set has to be re pressed manually.

• It has the VIDOM Diagnosesystem which stays for Voll Integriete Diagnose Optische Messpunkte and  is intended as a Completely Optical Integrated measurements Diagnose Sytstem.

With led diode lamp fitted in cardinal points of the chassis was possible to quickly diagnose a fault under a trained process performed by skilled service engineers.

  The set is build with a Modular chassis design because as modern television receivers become more complex the problem of repairing the receiver becomes more difficult. As the number of components used in the television receiver increases the susceptibility to breakdown increases and it becomes more difficult to replace defective components as they are more closely spaced. The problem has become even more complicated with the increasing number of color television receivers in use. A color television receiver has a larger number of circuits of a higher degree of complexity than the black and white receiver and further a more highly trained serviceman is required to properly service the color television receiver.
Fortunately for the service problem to date, most failures occur in the vacuum tubes used in the television receivers. A faulty or inoperative vacuum tube is relatively easy to find and replace. However, where the television receiver malfunction is caused by the failure of other components, such as resistors, capacitors or inductors, it is harder to isolate the defective component and a higher degree of skill on the part of the serviceman is required.
Even with the great majority of the color television receiver malfunctions being of the "easy to find and repair" type proper servicing of color sets has been difficult to obtain due to the shortage of trained serviceman.
At the present time advances in the state of the semiconductor art have led to the increasing use of transistors in color television receivers. The receiver described in this application has only two tubes, the picture tube and the high voltage rectifier tube, all the other active components in the receiver being semiconductors.
One important characteristic of a semiconductor device is its extreme reliability in comparison with the vacuum tube. The number of transistor and integrated circuit failures in the television receiver will be very low in comparison with the failures of other components, the reverse of what is true in present day color television receivers. Thus most failures in future television receivers will be of the hard to service type and will require more highly qualified servicemen.
The primary symptoms of a television receiver malfunction are shown on the picture tube of the television receiver while the components causing the malfunction are located within the cabinet. Also many adjustments to the receiver require the serviceman to observe the screen. Thus the serviceman must use unsatisfactory mirror arrangements to remove the electronic chassis from the cabinet, usually a very difficult task. Further many components are "buried" in a maze of circuitry and other components so that they are difficult to remove and replace without damage to other components in the receiver.
Repairing a modern color television receiver often requires that the receiver be removed from the home and carried to a repair shop where it may remain for many weeks. This is an expensive undertaking since most receivers are bulky and heavy enough to require at least two persons to carry them. Further, two trips must be made to the home, one to pick up the receiver and one to deliver it. For these reasons, the cost of maintaining the color television receiver in operating condition often exceeds the initial cost of the receiver and is an important factor in determining whether a receiver will be purchased.
Therefore, the object of this invention is to provide a transistorized color television receiver in which the main electronic chassis is easily accessible for maintenance and adjustment. Another object of this invention is to provide a transistorized color television receiver in which the electronic circuits are divided into a plurality of modules with the modules easily removable for service and maintenance. The main electronic chassis is slidably mounted within the cabinet so that it may be withdrawn, in the same manner as a drawer, to expose the electronic circuitry therein for maintenance and adjustment from the rear closure panel after easy removal. Another aspect is the capability to be serviced at eventually the home of the owner.

• It has a Transistorized horizontal deflection circuits  made up of a horizontal switching or output transistor, a diode, one or more capacitors and a deflection winding. The output transistor, operating as a switch, is driven by a horizontal rate square wave signal and conducts during a portion of the horizontal trace interval. A diode, connected in parallel with the transistor, conducts during the remainder of the trace interval. A retrace capacitor and the deflection yoke winding are coupled in parallel across the transistor-diode combination. Energy is transferred into and out of the deflection winding via the diode and output transistor during the trace interval and via the retrace capacitor during the retrace interval. 

  In some television receivers, the collector of the horizontal output transistor is coupled to the B+ power supply through the primary windings of the high voltage transformer.

 

• Above  a pair of expandable telescopic antennas,  hand grips are side placed for transport.

• The ITT IDEAL COLOR 1960 ST OSCAR 8 has headphone jack and plug in unit for standard add on capability.

• The set features a black matrix color picture tube.This invention relates to a black matrix color picture tube and a method for its fabrication and particularly to a high-contrast black matrix color picture tube and a method for its fabrication.

The phosphor screen of a so-called black matrix color picture tube has on its faceplate the formation of a nonluminous, light-absorptive powder layer (black matrix) for partly covering the phosphor layer so that the phosphor layer appears through aperture sections (matrix holes).  A method of reducing the inner surface reflection has been proposed, in which a material having virtually the same refractivity as the faceplate material, e.g., water glass, is filled in the gap between the faceplate and the black matrix layer. See, for example, JP-A-57-115749.

A black matrix color picture tube has a phosphor layer and black matrix layer formed on the inner surface of the faceplate. A layer of glass having a low softening point is provided between the phosphor layer and the inner surface of the faceplate and between the black matrix layer and the inner surface of the faceplate. The softening point of the glass is below the temperature at which the tube is subjected during a frit baking step employed in the fabrication of the tube. For example, a borophosphate glass is used as the layer of glass having a low softening point.

•  The set is a first in featuring  a new set of PAL decoder chips which has been introduced by Siemens, the TDA2560/TDA2522/TDA2530. The first two of these second -source the latest Philips/Mullard decoder i.c.s, with the TDA2560 as luminance and chrominance signal amplifier and the TDA2522 as the reference oscillator/chrominance demodulator. Interesting features of this set up are the fact that the burst signal passes through the chrominance delay line and the fact that the reference oscillator operates at 8.86MHz, a digital divider providing exactly 90° phase displaced 4.43MHz outputs without the need for a phase shift coil. The first UK produced chassis to use these i.c.s is the Tandberg CTV3, the larger UK setmakers staying for the time being with the TBA560C/TBA540/TCA800 combination. The third i.c. from Siemens is the TDA2530 which supersedes the well known TBA530 luminance/colour-difference signal matrix- ing i.c. The TDA2530 contains a negative feedback driver amplifier and internal clamping in addition to the matrixing network.

 

 

ITT Corporation (NYSE: ITT) is a global diversified manufacturing company with 2008 revenues of $11.7 billion. ITT participates in global markets including water and fluids management, defense and security, and motion and flow control. Forbes.com named ITT Corporation to its list of "America's Best Managed Companies" for 2008, and awarded the company the top spot in the conglomerates category.

,ITT's water business is the world's largest supplier of pumps and systems to transport, treat and control water, and other fluids. The company's defense electronics and services business is one of the ten largest US defense contractors providing defense and security systems, advanced technologies and operational services for military and civilian customers. ITT's motion and flow control business manufactures specialty components for aerospace, transportation and industrial markets.

In 2008, ITT was named to the Dow Jones Sustainability World Index (DJSI World) for the tenth time in recognition of the company's economic, environmental and social performance. ITT is one of the few companies to be included on the list every year since its inception in 1999.

The company was founded in 1920 as International Telephone & Telegraph. During the 1960s and 1970s, under the leadership of its CEO Harold Geneen the company rose to prominence as the archetypal conglomerate, deriving its growth from hundreds of acquisitions in diversified industries. ITT divested its telecommunications assets in 1986, and in 1995 spun off its non-manufacturing divisions, later to be purchased by Starwood Hotels & Resorts Worldwide.

In 1996, the company became ITT Industries, Inc., but changed its name back to ITT Corporation in 2006.



History

ITT was formed in 1920, created from the Puerto Rico Telephone Company co-founded by Sosthenes Behn.
Its first major expansion was in 1923 when it consolidated the Spanish Telecoms market into what is now Telefónica.
From 1922 to 1925 it purchased a number of European telephone companies. In 1925 it purchased the Bell Telephone Manufacturing Company of Brussels, Belgium, which was formerly affiliated with AT&T, and manufactured rotary system switching equipment. In the 1930s, ITT grew through purchasing German electronic companies Standard Elektrizitaetsgesellschaft (SEG) and Mix ; Genest, both of which were internationally active companies. Its only serious rival was the Theodore Gary & Company conglomerate, which operated a subsidiary, Associated Telephone and Telegraph, with manufacturing plants in Europe.

In the United States, ITT acquired the various companies of the Mackay Companies in 1928 through a specially organized subsidiary corporation, Postal Telegraph & Cable. These companies included the Commercial Cable Company, the Commercial Pacific Cable Company, Postal Telegraph, and the Federal Telegraph Company.



International telecommunications

International telecommunications manufacturing subsidiaries included STC in Australia and Britain, SEL in Germany, BTM in Belgium, and CGCT and LMT in France. Alec Reeves invented Pulse-code modulation (PCM), upon which future digital voice communication was based. These companies manufactured equipment according to ITT designs including the (1960s) Pentaconta crossbar switch and (1970s) Metaconta D, L and 10c Stored Program Control exchanges, mostly for sale to their respective national telephone administrations. This equipment was also produced under license in Poznań (Poland), and in Yugoslavia, and elsewhere. ITT was the largest owner of the LM Ericsson company in Sweden but sold out in 1960.




1989 breakup

In 1989 ITT sold its international telecommunications product businesses to Alcatel, now Alcatel-Lucent. ITT Kellogg was also part of the 1989 sale to Alcatel. The company was then sold to private investors in the U.S. and went by the name Cortelco Kellogg. Today the company is known as Cortelco (Corinth Telecommunications Corporation, named for Corinth, MS headquarters). ITT Educational Services, Inc. (ESI) was spun off through an IPO in 1994, with ITT as an 83% shareholder. ITT merged its long distance division with Metromedia Long Distance, creating Metromedia-ITT. Metromedia-ITT would eventually be acquired by Long Distance Discount Services, Inc. (LDDS) in 1993. LDDS would later change its name to Worldcom in 1995.

In 1995, ITT Corporation split into 3 separate public companies:

* ITT Corp. — In 1997, ITT Corp. completed a merger with Starwood Hotels & Resorts Worldwide, selling off its non-hotel and resorts business. By 1999, ITT completely divested from ITT/ESI; however, the schools still operate as ITT Technical Institute using the ITT name under license.
Also in 1999, ITT Corp. dropped the ITT name in favor of Starwood.
* ITT Hartford (insurance) — Today ITT Hartford is still a major insurance company although it has dropped the ITT from its name altogether. The company is now known as The Hartford Financial Services Group, Inc.
* ITT Industries — ITT operated under this name until 2006 and is a major manufacturing and defense contractor business.
o On July 1, 2006, ITT Industries changed its name to ITT Corporation as a result of its shareholders vote on May 9, 2006.



Purchase of International Motion Control (IMC)

An agreement was reached on June 26, 2007 for ITT to acquire privately held International Motion Control (IMC) for $395 million. The deal was closed and finalized in September 2007. An announcement was made September 14, 2010, to close the Cleveland site.
Purchase of EDO

An agreement was reached September 18, 2007 for ITT to buy EDO Corporation for $1.7 billion.
After EDO shareholders' approval, the deal was closed and finalized on December 20, 2007.


Purchase of Laing

On April 16, 2009, ITT announced it has signed a definitive agreement to acquire Laing GmbH of Germany, a privately held leading producer of energy-efficient circulator pumps primarily used in residential and commercial plumbing and heating, ventilating and air conditioning (HVAC) systems.


2011 breakup

On January 12, 2011, ITT announced a transformation to separate the company into 3, stand-alone, publicly-traded, and independent companies.


HISTORY OF Standard Elektrik Lorenz AG IN GERMAN:

Die Standard Elektrik Lorenz AG (heute Alcatel-Lucent Deutschland AG) ist ein Unternehmen der Nachrichtentechnik (früherer Slogan: SEL – Die ganze Nachrichtentechnik) mit Hauptsitz in Stuttgart. Zur Nachrichtentechnik zählen auch Informations- und Kommunikationstechnik, Telekommunikationstechnik (SEL war für die Röchelschaltung bekannt) und früher Fernmeldetechnik oder Schwachstromtechnik. Einen weiteren Geschäftsbereich hatte das Unternehmen in der Bahnsicherungstechnik, so wurden für die Deutsche Bundesbahn Relaisstellwerke und elektronische Stellwerke mit den dazugehörigen Außenanlagen (Signale, Gleisfreimeldeanlagen, Weichenantriebe) sowie die Linienzugbeeinflussung entwickelt und gebaut, welche auch bei ausländischen Bahnen Abnehmer fanden. Der Bereich gehört seit 2007 als Thales Transportation Systems GmbH (seit 02.2011 vorher Thales Rail Signalling Solutions GmbH) zum Thales-Konzern. Die bereits 1998 ausgegliederten Bereiche Alcatel Air Navigation Systems und SEL Verteidigungssysteme sind ebenfalls heute in Thales Deutschland beheimatet.

„Goldsuper Stereo 20“ (1961)
Das Flaggschiff der erfolgreichen Schaub-Lorenz Kofferradios der sechziger Jahre: Touring 70 Universal
Erster Digitalfernseher der Welt (1983)

Bis 1987 gehörte SEL zusammen mit anderen auf dem Sektor Telekommunikation in anderen Ländern tätigen Schwesterfirmen zum US-amerikanischen Mischkonzern International Telephone and Telegraph (ITT). ITT verkaufte die Aktien-Mehrheit an den ITT-Telekommunikationsfirmen an die französische Compagnie Générale d’Electricité (CGE), die nach der Zusammenfassung mit den eigenen Telekommunikationsaktivitäten daraus die Alcatel N.V. bildete.

Die Standard Elektrik Lorenz AG wurde 1993 in Alcatel SEL AG umbenannt. Die Aktienmehrheit liegt mit über 99 % bei der Alcatel. Mit der Fusion von Alcatel und Lucent zu Alcatel-Lucent am 1. Dezember 2006 und der Neu-Firmierung beider Unternehmen in Deutschland zur Alcatel-Lucent Deutschland AG entfiel der Zusatz SEL.


Geschichte

Die beiden Stammfirmen des Unternehmens, die Mix & Genest AG und die Telegraphenbauanstalt von C. Lorenz, wurden 1879 bzw. 1880 gegründet. Das erste Patent von Mix & Genest datiert von 1883, das erste Patent von C. Lorenz ist aus dem Jahr 1902.

Das Unternehmen Mix & Genest war wesentlicher Teil der Standard Elektrizitäts-Gesellschaft (SEG), in die auch die Süddeutsche Apparatefabrik (SAF), die 1875 von F. Heller als "Friedrich Heller, Fabrik Elektrotechnischer Apparate" gegründet wurde, integriert wurde. D

er technische Schwerpunkt von Mix & Genest bzw. SEG sowie der C. Lorenz AG war der klassischen Fernmelde- bzw. Funktechnik zuzuordnen. Die C. Lorenz AG baute in den 1920er und 1930er Jahren Großsender für den neu gegründeten Rundfunk.

1930 übernahm die International Telephone and Telegraph Company (ITT) die Aktienmehrheit der Mix & Genest AG und der C. Lorenz AG.

Die C. Lorenz AG positionierte sich mit der Übernahme der G. Schaub Apparatebau-Gesellschaft mbH im Jahr 1940 in der Entwicklung und Herstellung von Rundfunkempfängern. Ab dem Jahr 1950 wurden alle Geräte bei Schaub in Pforzheim gefertigt. 1952 wurde das Typenprogramm beider Unternehmen verschmolzen und der Lorenz-Radio-Vertrieb in die Firma Schaub integriert. Ab 1955 wurden die Geräte unter dem Namen Schaub-Lorenz vertrieben.

1956 wurde das Unternehmen SEG in Standard Elektrik AG umbenannt. Ebenfalls 1956 wurde ein Kabelwerk gegründet. Wesentlicher Motor für das 1957 gegründete Informatikwerk war Karl Steinbuch, der von 1948–1958 dem Unternehmen, zuletzt als Technischer Direktor und Leiter der Zentralen Forschung, angehörte.

1958 erfolgte die Vereinigung der Standard Elektrik AG mit der C. Lorenz AG zur Standard Elektrik Lorenz AG (SEL).

Die Standard Elektrik Lorenz AG übernahm 1961 die Graetz KG. Die Firmenteile Schaub-Lorenz und Graetz waren zusammen mit einem Bildröhrenwerk Bestandteil der Unternehmensgruppe Audio Video der SEL AG, die 1979 als Audio-Video-Elektronik in die ITT ausgegliedert wurde. Die Produkte, die unter anderem Fernsehgeräte, Radios, Autoradios, Kassettenrecorder, Weltempfänger und Lautsprecherboxen umfassen, wurden fortan unter dem Namen ITT Schaub-Lorenz vertrieben.

Versuche, auf dem neuen Gebiet der Raumfahrt-Elektronik Fuß zu fassen, waren auf folgende Produkte beschränkt:

* AZUR: Telemetrie/Telekommandogeräte
* Spacelab: Datenerfassung/Kommandoterminal.

SEL entwickelte zu Beginn der 1970er Jahre das Präzisionsanflugverfahren SETAC. Dieser Unternehmensbereich wurde im Jahre 1987 von der finnischen Firma Nokia übernommen.

1976 hatte SEL ein Grundkapital von 357 Mio. DM bei 33.000 Beschäftigten und einem Umsatz von 2,6 Mrd. DM.

1983 stellte SEL auf der Internationalen Funkausstellung Berlin 1983 mit dem ITT Digivision den weltweit ersten Fernseher mit digitaler Signalverarbeitung vor.

2003 wurden die Markenrechte am Namen Schaub Lorenz an die italienische General Trading SpA verkauft. Die neugegründete Schaub Lorenz International GmbH vertreibt seitdem unter dem alten Markennamen Schaub-Lorenz importierte Konsumelektronik aus dem unteren Preisbereich.
