Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and information about some of the electronic, electrical and electrotechnical technology relics that the Frank Sharp Private museum has accumulated over the years .

Premise: There are lots of vintage electrical and electronic items that have not survived well or even completely disappeared and forgotten.

Or are not being collected nowadays in proportion to their significance or prevalence in their heyday, this is bad and the main part of the death land. The heavy, ugly sarcophagus; models with few endearing qualities, devices that have some over-riding disadvantage to ownership such as heavy weight,toxicity or inflated value when dismantled, tend to be under-represented by all but the most comprehensive collections and museums. They get relegated to the bottom of the wants list, derided as 'more trouble than they are worth', or just forgotten entirely. As a result, I started to notice gaps in the current representation of the history of electronic and electrical technology to the interested member of the public.


Following this idea around a bit, convinced me that a collection of the peculiar alone could not hope to survive on its own merits, but a museum that gave equal display space to the popular and the unpopular, would bring things to the attention of the average person that he has previously passed by or been shielded from. It's a matter of culture. From this, the Obsolete Technology Tellye Web Museum concept developed and all my other things too. It's an open platform for all electrical Electronic TV technology to have its few, but NOT last, moments of fame in a working, hand-on environment. We'll never own Colossus or Faraday's first transformer, but I can show things that you can't see at the Science Museum, and let you play with things that the Smithsonian can't allow people to touch, because my remit is different.

There was a society once that was the polar opposite of our disposable, junk society. A whole nation was built on the idea of placing quality before quantity in all things. The goal was not “more and newer,” but “better and higher" .This attitude was reflected not only in the manufacturing of material goods, but also in the realms of art and architecture, as well as in the social fabric of everyday life. The goal was for each new cohort of children to stand on a higher level than the preceding cohort: they were to be healthier, stronger, more intelligent, and more vibrant in every way.

The society that prioritized human, social and material quality is a Winner. Truly, it is the high point of all Western civilization. Consequently, its defeat meant the defeat of civilization itself.

Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

OLD, but ORIGINAL, Well made, Funny, Not remotely controlled............. and not Made in CHINA.

ITT DIGIVISION 3447 OSCAR YEAR 1986.





The ITT DIGIVISION 3447 OSCAR is a Digital color television set with 20 inches screen format and 1 speaker sound system but featuring all features of a bigger DIGIVISION ITT SET and is because of features and format slightly rare. Back a SCART connector is present even if the 20" format wasn't required at the time to do so.

A SCART Connector (which stands for Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) is a standard for connecting audio-visual equipment together. The official standard for SCART is CENELEC document number EN 50049-1. SCART is also known as Péritel (especially in France) and Euroconnector but the name SCART will be used exclusively herein. The standard defines a 21-pin connector (herein after a SCART connector) for carrying analog television signals. Various pieces of equipment may be connected by cables having a plug fitting the SCART connectors. Television apparatuses commonly include one or more SCART connectors.
Although a SCART connector is bidirectional, the present invention is concerned with the use of a SCART connector as an input connector for receiving signals into a television apparatus. A SCART connector can receive input television signals either in an RGB format in which the red, green and blue signals are received on Pins 15, 11 and 7, respectively, or alternatively in an S-Video format in which the luminance (Y) and chroma (C) signals are received on Pins 20 and 15. As a result of the common usage of Pin 15 in accordance with the SCART standard, a SCART connector cannot receive input television signals in an RGB format and in an S-Video format at the same time.
Consequently many commercially available television apparatuses include a separate SCART connectors each dedicated to receive input television signals in one of an RGB format and an S-Video format. This limits the functionality of the SCART connectors. In practical terms, the number of SCART connectors which can be provided on a television apparatus is limited by cost and space considerations. However, different users wish the input a wide range of different combinations of formats of television signals, depending on the equipment they personally own and use. However, the provision of SCART connectors dedicated to input television signals in one of an RGB format and an S-Video format limits the overall connectivity of the television apparatus. Furthermore, for many users the different RGB format and S-Video format are confusing. Some users may not understand or may mistake the format of a television signal being supplied on a given cable from a given piece of equipment. This can result in the supply of input television signals of an inappropriate format for the SCART connector concerned.
This kind of connector is todays obsoleted !
The present 32 programs PLL tuner invention pertains to the field of tuning systems including a prescaler for dividing the frequency of the local oscillator signal by a factor selected to produce a divided frequency signal with a frequency suitable for processing in digital portions of the tuning system.

Phase locked loop (PLL) tuning systems are employed in television receivers since they can readily be digitally controlled and can produce local oscillator signals with extreme accuracy. Such PLL tuning systems include a source of reference frequency signals typically including a crystal oscillator, a fixed divider, commonly referred to as a prescaler, for dividing the frequency of a local oscillator signal to produce a frequency divided signal, a programmable divider for dividing the frequency divided signal by a programmable factor to produce a further frequency divided signal and a phase comparator for producing an error signal representing the phase and frequency deviation between the further frequency divided signal and the reference frequency signal. The error signal, which comprises pulses the width of which represents the magnitude of the deviation and the amplitude of which represents the sense of the deviation, is filtered to produce a tuning voltage for the local oscillator. The fixed factor is selected so that the frequency of the frequency divided signal can be processed by digital circuitry which comprises the remaining portion of the PLL tuning system. The programmable factor, commonly referred to as N, is set in accordance with the channel number of the selected channel. When the deviation between the further frequency divided signal and the reference frequency signal is at a predetermined small value, the loop is said to be locked. At this point, the frequency of the local oscillator signal is directly proportional to the frequency of the reference frequency signal by the programmable factor N.

The prescaler employed in such PLL tuning systems typically includes a high gain input amplifier arrangement to enhance the sensitivity of the prescaler. Such an amplifier arrangement can and typically does oscillate. This self-oscillation can occur at any frequency including that at or very near to the frequency of the frequency divided signal produced by the prescaler in response to the local oscillator signal for a preselected channel.





























































ITT DIGIVISION First Digital Television in the world.

This model and bigger models were introducing the ITT DIGIVISION DIGITAL SIGNAL PROCESSING in the television consumer market.

The official introduction was in 1984 in Germany and this is a ITT DIGIVISION 3447 OSCAR model which was marketed in 1985- 1986 in Europe employing the first generation of the ITT DIGIVISION DIGITAL SIGNAL PROCESSING CHASSIS DIGIT2000.

In the years after 1986 other television fabricants started using and developing television sets
employing the DIGIT2000 DIGIVISION ITT TECHNOLOGY.

In 1984, after ITT released on the market the DIGIVISION ITT DIGIT2000, only one constructor have followed immediately this technology; it was SINUDYNE an extint Italian industry.
---------------

It's a 21 Inches color (51Cm) stereo hi-fi with 1 speaker, on table set with 40 programs and remote + Teletext feature.

ITT DIGIVISION 3447 OSCAR  DIGITAL Colour television receiver or set , are known in which the majority of signal processing that takes place therein is carried out digitally. That is, a video or television signal is received in a conventional fashion using a known analog tuning circuit and then, following the tuning operation, the received analog television signal is converted into a digital signal and digitally processed before subsequently being converted back to an analog signal for display on a colour cathode ray tube.
In a conventional television receiver, all signals are analog-processed. Analog signal processing, however, has the problems at the video stage and thereafter. These problems stem from the general drawbacks of analog signal processing with regard to time-base operation, specifically, incomplete Y/C separation (which causes cross color and dot interference), various types of problems resulting in low picture quality, and low precision of synchronization. Furthermore, from the viewpoints of cost and ease of manufacturing the analog circuit, a hybrid configuration must be employed even if the main circuit comprises an IC. In addition to these disadvantages, many adjustments must be performed.

In order to solve the above problems, it is proposed to process all signals in a digital form from the video stage to the chrominance signal demodulation stage. In such a digital television receiver, various improvements in picture quality should result due to the advantages of digital signal processing.
Therefore digital television signal processing system introduced in 1984 by the Worldwide Semiconductor Group (Freiburg, West Germany) of International Telephone and Telegraph Corporation is described in an ITT Corporation publication titled "VLSI Digital TV System--DIGIT 2000." In that system color video signals, after being processed in digital (binary) form, are converted to analog form by means of digital-to-analog converters before being coupled to an image displaying kinescope. The analog color video signals are coupled to the kinescope via analog buffer amplifiers and video output kinescope driver amplifiers which provide video output signals at a high level suitable for driving intensity control electrodes of the kinescope.

The ITT DIGIVISION 3447 OSCAR  Is a multistandard set and relates to a digital multistandard decoder for video signals and to a method for decoding video signals.
Colour video signals, so-called composite video, blanking and sync signals (CVBS) are essentially composed of a brightness signal or luminance component (Y), two colour difference signals or chrominance components (U, V or I, Q), vertical and horizontal sync signals (VS, HS) and a blanking signal (BL).
The different coding processes, e.g. NTSC, PAL and SECAM, introduced into the known colour television standards, differ in the nature of the chrominance transmission and in particular the different systems make use of different colour subcarrier frequencies and different line frequencies.
The following explanations relate to the PAL and NTSC systems, but correspondingly apply to video signals of other standards and non-standardized signals.
The colour subcarrier frequency (fsc) of a PAL system and a NTSC system is fsc(NTSC) = 3.58 MHz or fsc(PAL) = 4.43 MHz.
In addition, in PAL and NTSC systems the relationships of the colour subcarrier frequency (fsc) to the line frequency (fh) are given by fsc(NTSC) = 227.50 * fh or 4•fsc(NTSC) = 910 • fh fsc(PAL) = 283.75 * fh or 4•fsc(PAL) = 1135 • fh so that the phase of the colour subcarrier in the case of NTSC is changed by 180°/line and in PAL by 270°/line.
In the case of digital video signal processing and decoding the prior art fundamentally distinguishes between two system architectures. These are the burst-locked architecture and the line-locked architecture, i.e. systems which operate with sampling frequencies for the video signal, which are produced in phase-locked manner to the colour subcarrier frequency transmitted with the burst pulse or in phase-locked manner with the line frequency, respectively.

The principal advantage of the present invention is a color television receiver is provided having a fully digital color demodulator wherein the luminance signal and the chrominance signals are separated and digitally processed prior to being converted to analog signals in that the all-digital signal processing largely eliminates the need for nonintegratable circuit elements, i.e., particularly coils and capacitors, and that the subcircuits can be preferably implemented using integrated insulated-gate field-effect transistor circuits, i.e., so-called MOS technology. This technology is better suited for implementing digital circuits than the so-called bipolar technology.

The ITT DIGIVISION 3447 OSCAR   is a multisound tv digital sound processing.


This tellye is fabricated by SEL / ITT (Standard Elektrik Lorenz), the same fabricant of all semiconductors related to the ITT DIGIVISION chipset.

It' fitted with the ITT DIGI 3 110° CHASSIS which is the first generation of DIGITAL CHASSIS for television with the DIGIT2000 chipset instead of the previous MAA CHIPSET series.
This is the father of all the DIGITAL TECHNOLOGY applied to Video and Audio Processing for Television applications.

This ITT DIGIVISION DIGIT2000 it is an even today a superior example of the unique quality video and audio processing.

The ITT DIGIVISION DIGIT2000 System has the unique capabilty to process video signal without any kind of artifacts or pixeling or any noise impurity related to DIGITAL Signal Processing.
The video signal in the DIGITAL DOMAIN OF ITT DIGIVISION DIGIT2000 has NO RIVALS. The processing is ULTRA FAST and doesn't mix or produce any type of "additions" unrelated to Original picture, it's every time natural and not artificial like all LCD AND LED CRAP SET.

Pictures produced by a ITT DIGIVISION DIGIT2000 Tellye have unsurpassed, even today, quality picture:

- High contrast bright, because of the digital processing, lot of more video dinamic is gained.

- High precision detailed picture, because of the digital processing any particular of the picture even the little point is processed and improved.

- Super color dynamic, because of the digital processing, colors are gaining power and precision details but without producing any kind of no reality like many modern CRAPPY LCD & Co.

The ITT DIGIT2000 chipset is the core of all Audio and Video processing. From the composite CVBS signal all processing is executed in the DIGIT2000 chipset board which improves signal quality and dynamic without needing any regulations or setup.

This technology is introducing even an another important group of revolutionary features:
NO MORE REGULATIONS needed via trimmers and / or potentiometers.

All setups regarding picture / CRT / SOUND are executed in the digital domain via a special kind of setup feasible via special tools or via a SERVICE MODE SETUP and parametrized via remote
controller and front display steps followed engineering menu.

It's Useless to say that the pictures produced by this set are excellent for precision and brightness and quality.

Even the sound has superb bass AUDIO and response to all sounds in perfect ways.

Here is the Announcement article from DER SPIEGEL a GERMAN journal which was discussing the introducing marketing of the DIGIVISION ITT TECHNOLOGY:

(This article is in original GERMAN Language)

FERNSEHEN

Vorteil im Verborgenen

Die ersten computergesteuerten Fernseher kommen in die Geschäfte - für den Verbraucher bringen sie vorerst kaum Vorteile. *
Das Gerät sieht aus wie jeder andere Fernseh-Apparat, auch Bild und Ton sind keineswegs besser. Aber nach Ansicht der Ingenieure ist es ein "technologischer Meilenstein".
Gemeint ist das neueste Gerät der Standard Elektrik Lorenz (SEL) - ein computergesteuerter Fernseher namens Digivision. "Mit Freude und Stolz" hatte SEL-Vorstandschef Helmut Lohr seinen
Aktionären den Apparat auf der letzten Hauptversammlung präsentiert. Ende dieses Monats soll es nun den digitalen Fernseher zu kaufen geben.
Vorerst allerdings dürfte der rund 2700 Mark teure Apparat allein fortschrittshungrige Techniker begeistern. Es ist der erste Farbfernseher der Welt, der Bild- und Tonsignale digital, wie ein Computer, verarbeitet.
Die Idee stammt von dem jugoslawischen Ingenieur Lubo Micic. Der hatte bereits vor zehn Jahren bei der Firma Intermetall in Freiburg, einer Tochter des amerikanischen ITT-Konzerns, zu dem auch SEL gehört, die Grundlage für Digivision entwickelt.
Mikroprozessoren, so schlug Micic vor, sollten die von den Sendern kommenden Fernsehsignale in Zahlencodes verwandeln. Um eine optimale Bildqualität zu erreichen, müßte eine andere Rechnereinheit die in digitale Codes verwandelten Signale überprüfen und, falls nötig, korrigieren. Die so aufbereiteten Signale würden dann wieder in ihre ursprüngliche Wellenform gebracht und das Fernsehbild produzieren.
Doch vor zehn Jahren wußten die Techniker die nahezu unbegrenzten Möglichkeiten der neuen Mikroprozessoren noch nicht recht zu nutzen. Die fingernagelgroßen Chips, die alle zentralen Funktionen eines großen Computers übernahmen, waren gerade erst zwei Jahre auf dem Markt.
Inzwischen hat Intermetall mehr als 40 Millionen Mark investiert, um Chips zu entwickeln, die ohne Zeitverzögerung die wellenförmigen Fernsehsignale in digitale Codes umwandeln. Und weitere Millionen sind erforderlich, damit auch der Verbraucher die Wunder der neuen Technik nutzen kann. So soll der Digital-Fernseher
eines Tages Bildstörungen wie Flimmern oder Streifen auf der Mattscheibe automatisch beseitigen. Der Zuschauer soll auch Standbilder oder vergrößerte Bildausschnitte wählen können.
Doch dazu müssen die digitalen Fernsehsignale durch einen elektronischen Speicher geschickt werden, der etwa die gewünschten Standbilder später wieder hergibt. Ein solcher Speicher aber ist bislang in keinem der jetzt käuflichen Geräte eingebaut.
Das Problem ist die unvorstellbare Menge an Daten, die ein solcher Speicher aufnehmen müßte. Um das Standbild zu liefern, muß der Speicher alle für das Fernsehbild notwendigen Informationen festhalten können. Bei einem Farbbild sind das rund vier Millionen digitaler Informationen (bits) pro Sekunde.
Diese Datenflut läßt sich mit den heute verfügbaren Speichern auf dem engen Raum eines Fernsehgeräts kaum verarbeiten. Mehr als 250 der heute üblichen Chips wären erforderlich. Der Preis für das Gerät stiege dadurch um mindestens 1500 Mark.
Frühestens in zwei Jahren, so rechnen die Experten, wird es möglich sein, die Zahl der für den Datenspeicher notwendigen Chips drastisch zu reduzieren. Dann könnten störungsfrei arbeitende Fernseher mit Standbild und Ausschnittvergrößerung als Luxusmodelle mit etwa 600 Mark Aufpreis angeboten werden.
Bislang wirken sich die Vorzüge des neuen Fernsehers vor allem für die Hersteller aus: Die Chips machen den Fernseher computergerecht. Zum Beispiel die Einstellung von Helligkeit und Bildschärfe sowie die Endkontrolle im Werk können von einem Rechner übernommen werden.
Die Folge: Die Geräte kommen noch schneller vom Band. Seit Mitte der siebziger Jahre fiel die Produktionszeit für einen Fernseher bereits von acht auf zwei Stunden. Mit Hilfe der Digitaltechnik läßt sich nun noch einmal mindestens eine halbe Stunde einsparen.
Solche Rationalisierungsvorteile weckten das Interesse der Konkurrenz. Bereits 18 Gerätehersteller aus aller Welt, darunter Sony, Grundig und Blaupunkt, verhandeln mit Intermetall. Die für 1983 vorgesehene Produktion von 200 000 der neuen Chips ist bereits verkauft. Im kommenden Jahr soll die zehnfache Menge produziert werden.
Der ITT-Konzern hat schon jetzt 60 Millionen Mark in die Fabrikation der Chips gesteckt. Bis 1987 will der US-Multi noch einmal 350 Millionen Mark investieren. "Wir sind", so ein Intermetall-Manager, "vielleicht ein halbes Jahr weiter als die Konkurrenz, und diesen Vorsprung müssen wir nutzen."
In der Tat ziehen die Konkurrenten nach. Halbleiter-Produzenten wie Siemens, Texas Instruments oder Motorola sehen ebenfalls eine Chance, ihr Bauteile-Geschäft auszuweiten. Immerhin werden jährlich weltweit rund 50 Millionen Fernseher gebaut - für die Chips-Hersteller tut sich da ein ganz neuer Markt auf.
Für den Verbraucher dagegen, der sich ein neues Fernsehgerät anschafft, liegen die Vorteile der Digital-Technik eher noch im Verborgenen: Im Gerät ist weniger drin - sechs Mikrochips ersetzen rund 300 von etwa tausend herkömmlichen Bauteilen.
Im Gebrauch muß deshalb ein solcher Apparat zuverlässiger sein: Was nicht drin ist, so ein alter Techniker-Schnack, kann auch nicht kaputtgehen. _(Sechs Chips einer ITT-Leiterplatte ) _(ersetzen rund 300 konventionelle ) _(Bauteile. )
Sechs Chips einer ITT-Leiterplatte ersetzen rund 300 konventionelle Bauteile.

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.[1] Its first major expansion was in 1923 when it consolidated the Spanish Telecoms market into what is now Telefónica.[2] 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.[1] Also in 1999, ITT Corp. dropped the ITT name in favor of Starwood.[7]
* 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.[12] 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.[1]

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. Der 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. [2]

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.[2]

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

The most important thing to remember about the Comment Rules is this:
The determination of whether any comment is in compliance is at the sole discretion of this blog’s owner.

Comments on this blog may be blocked or deleted at any time.
Fair people are getting fair reply. Spam and useless crap and filthy comments / scrapers / observations goes all directly to My Private HELL without even appearing in public !!!

The fact that a comment is permitted in no way constitutes an endorsement of any view expressed, fact alleged, or link provided in that comment by the administrator of this site.
This means that there may be a delay between the submission and the eventual appearance of your comment.

Requiring blog comments to obey well-defined rules does not infringe on the free speech of commenters.

Resisting the tide of post-modernity may be difficult, but I will attempt it anyway.

Your choice.........Live or DIE.
That indeed is where your liberty lies.
