SCHAUB LORENZ (ITT) 8838 I YEAR 1987.

The SCHAUB LORENZ (ITT) 8838 I is a 27 inches color television with CTI (color transient Improvement describe the color transient improvement (CTI) involving the detection and sharpening the edges in chrominance.) CTI Picture Improvements circuitry in which colour signal, e.g. the line-sequential colour difference signals (R-Y,B-Y), is processed by an edge steepening circuit e.g. a colour transient improver and/or a two-line delay line in which the colour signals from two lines are added. The delay line may be part of a drop-out compensation circuit in which the colour signal of line n is replaced by the signal present for line n-2. A CCD-line may be used as the two-line delay line, and an amplitude limiter included. ADVANTAGE - Increased picture sharpness and improved signal-to-noise ratio.The present invention relates to a circuit for enhancing chrominance transitions in real-time video reception.

In the past analog commercial TV transmission standards, the limited bandwidth of the transmitted chrominance (or chrominance difference) signals causes the received images to have perceptibly blurred colour transition edges. This is especially evident if the received image contains geometrical patterns, e.g. test-colour bars, and results in the loss of detail detectable in complex multicoloured fine patterns.

In order to improve the quality of the received images, it is necessary to provide the receiver end with circuits capable of restoring, as far as possible, the frequency components in the chrominance signals which have been filtered away by the requirements of the reduced transmission bandwidth: in this way, the temporal duration of the chrominance transition edges, and thus the spatial extent of the chrominance transitions on the TV screen, can be reduced, and the edge definition improved. Circuits of this type are called "Color Transient Improvement" ("CTI") or Chrominance Transition Enhancement circuits.

An important constraint on chrominance transition enhancement circuits is the need to ensure that the center of the chrominance transition is unaffected by the enhancement process, so that the center of the chrominance transition after the enhancement process is still aligned with the center of the associated transition in the luminance signal. Also, it is necessary to leave gradual transitions in time unaltered; preserve, and possibly enhance, fine patterns; prevent the introduction in the image of additional distortions; and ensure that the existing noise components are not accentuated.

It has 40 programs PLL synthesizer tuning sytem, remote, SCART socket, headphone jack and audio tone regulations.
The system employs a frequency synthesizer for tuning the receiver's local oscillator to a selected television channel. For fine tuning, the system employs a fine tuning key which doubles as a channel selection key. Actuation of this key places the system in a fine tuning mode, and a logic circuit responds to actuation of a channel-up or channel-down key for causing the receiver to be fine tuned in the selected direction. In the preferred embodiment, fine tuning and channel selection are controlled by the logic circuit so as to occur during the receiver's vertical interval to eliminate digital switching noise from the receiver's image. Television receivers of the type under consideration frequently include a frequency synthesizer for tuning the receiver's local oscillator to the nominal carrier frequency of a selected television channel. Generally, the frequency synthesizer compares the local oscillator frequency to a reference frequency associated with the selected channel, and then varies the local oscillator frequency until it equals the reference frequency. Presumably, the receiver will now be correctly tuned to the selected channel. A programmable frequency divider counter is connected between the output of a reference oscillator and a phase comparator to which the output of the local oscillator in the tuner also is applied. The phase comparator output provides a tuning voltage for controlling the tuning of the local oscillator. A microprocessor is used to control the count of the programmable frequency divider and initially to set a count corresponding to the selected channel in a counter connected between the output of the local oscillator and the phase comparator. The present invention resides in part on the recognition that a control system for a television receiver, including a microprocessor (also referred to as a micro-computer or micro-controller) and a serial data bus, for generating and distributing digital control signals for various sections of the television receiver, may also be used as an integral part of a digital AFT unit including a counter to control the counter and to evaluate the counts accumulated by the counter during a measurement period in order to evaluate the frequency of the IF picture carrier. More specifically, a preferred embodiment of the invention includes a microprocessor, a bi-directional serial data bus, and a counter.

PLL SYNTHESIZED TUNING System Concepts:

INTRODUCTION Digital tuning systems are fast replacing the conventional mechanical systems in AM FM and television receivers The desirability of the digital approach is mainly due to the following features * Precise tuning of station frequencies
* Exact digital frequency display
* Keyboard entry of desired frequency
* Virtually unlimited station memory
* Up down scanning through the band
* Station ‘‘search’’ (stop on next active station)
* Power on to the last station
* Easy option for time-of-day clock In addition
" recent "developments in large scale integrated circuit technology and new varactor diodes for the AM band have made the cost-benefit picture for digital tuning very attractive System partitioning is extremely important in optimizing this cost-benefit picture as will be discussed.

SYSTEM DESCRIPTION
A simplified block diagram of a typical digitally tuned receiver is shown in Figure 1 Notice this receiver could be one for AM FM marine radio or television it makes no difference The frequency synthesizer block generates the local oscillator frequency for the receiver just as a conventional mechanical tuner would However the phase-locked-loop (PLL) acts as an integral frequency multiplier of an accurate crystal controlled reference frequency while the mechanical type provides a continuously variable frequency output with no reference Some method of controlling the value of the multiplier for channel tuning must be provided The other RF IF and audio video circuitry will be the same as in the mechanical tuning method There are many different ways to partition the frequency synthesizer system to perform the digital tuning function................

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.

** The set has a Teletext feature comprising a receiver of teletext transmissions, under the form of a plurality of pages, inserted in the television signal, and divided into groups, for each of which an index page is available, comprising means for receiving and demodulating a television signal, furthermore decoding means for detecting the associated teletext signal and selection means for selecting a chosen page from those transmitted, and memory means for memorising at least one of the chosen teletext pages.
Receivers of teletext transmissions having the above mentioned characteristics are known.
The most recent of such receivers, those according to the TOP system (Table Of Pages, note the European patent application 0 264 565 or "Rundfunktechnische Mitteilungen", vol. 31, no. 2, 30 April 1987, Gerhard Eitz et al., "TOP-Ein Verfahren zur vereinfachten Anwahl von Fernsehtext-Tafeln durch den Zuschauer" for example) present numerous improvements for aiding the user to refer to the teletext, an operation famous for not being very user friendly for various reasons.
However also in such modern receivers, the Italian user that is consulting a Televideo page (a name in which RAI refers to teletext), for example belonging to the group "football", that being page N° 229, in order to return to the "football" index i.e. to page N°201, must depress three keys in succession 2, 0, 1; it is supposed that the user remembers the index number; otherwise it is necessary to return to the general index (100); from this point to the sports index (200) and finally to the Football group index (201).
The invention is based on the knowledge of the above inconvenience that represents a drawback in the actual teletext system.
The object of the invention is to allow the user to display the index page to which the chosen page belongs without a waiting interval.
It relates to a receiver of teletext transmissions, under the form of a plurality of pages, inserted in the television signal, and divided into groups, for each of which an index page is available, comprising means for receiving and demodulating a television signal, furthermore decoding means for detecting the associated teletext signal and selection means for selecting a chosen page from those transmitted, and memory means for memorising at least one of the chosen teletext pages; the characterising principle of the invention consists in the fact that the receiver comprises additional means for allowing the direct selection of the group index page to which the chosen page belongs.On the screen you will see at first teltext function call the  message "Automatic Multipage Process"

The set was featuring the COMPACT B2 chassis and first time A square screen S4 CRT TUBE (SEL).

These sets were everlasting types exception for the LOPT / FBT trasformer failing (almost all) often but replaced with non original (HR-DIEMEN) had solved the problem.



Started in 1921 by Georg von Schaub as Schaub-Elektrizitätsgesellschaft and was located in the Charlottenburg district of Berlin, Germany, originally manufacturing various electric equipment but entered the radio receiver market in 1923. The name of the company was changed to G. Schaub Apparatebau Gesellschaft GmbH in 1925 but continued to use plain Schaub as it's trademark and it became one of the better known manufacturers of radios in central Europe. Moved to Pforzheim-Dillweissenstein in 1934 and was taken over by C. Lorenz in 1940 although the company operated mostly independently until the early 50's. Restarted production of loudspeakers and receivers in 1946 or as soon as the occupation forces allowed and sold consumer products initially as Schaub and as later as Schaub-Lorenz, all manufacture of Lorenz CE products was actually handed over to the company in 1950 due to the blockade of Berlin by the Soviet occupation forces, the Schaub company was finally merged with the rest of the C. Lorenz companies in 1958 although the name was used at the least partially up until the sale of the Lorenz consumer division to Nokia in 1988.



One side Note:
The advert says "ITT Technik der Welt" (ITT the world Technology) indeed the contribution given by these organizations toghether the products of them increased man's life quality on certains aspects, so no surprises if today quality is heavily lowered by chinese market and other society crap mixtures, because anyway at the end it's a man choice.

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:

* 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.


Schaub oder Lorenz, beide Firmen haben ihre Wurzeln in Berlin !

Aber zunächst zu Lorenz:

Carl Lorenz betreibt seit 1870 eine mechanische Werkstatt in Berlin und gründet 1880 eine Telegraphenbauanstalt, eine Fabrik für elektrisches Licht, elektrische Eisenbahnen, Kunst und Industrie. Robert Held erwirbt im Jahr 1890 mit 27 Jahren die Firma von der Witwe Lorenz und wandelt 1906 die gesamte Firma in die C. Lorenz AG um und befasst sich mit dem Bau von Lichtbogen Systemen zur Erzeugung ungedämpfter Schwingungen. Mit einem "Lorenz-Poulsen-Sender" strahlt die Lorenz AG 1920 erstmals von der Versuchsfunkstelle in Eberswalde Rundfunksendungen in Deutschland ab.
1923 wurden die ersten Radiogeräte und Detektorempfänger produziert.
Robert Held stirbt im Jahr 1924. Am 1. April 1926 wird die Lorenz-Radio-Vertriebsgesellschaft mbH gegründet und ein Jahr später erwirbt die Fa. Lorenz die Patente der Firma Huth in Hannover.
Nach dem Tod von Robert Held wurde 1930 die Aktienmehrheit an die Standard Elektrizitätsgesellschaft (SEG) verkauft, die dem amerikanischen Unternehmen ITT gehörte.
Im Jahr 1935 ließ Lorenz die drehbare Ferritantenne patentieren, die später in Rundfunkgeräten eingesetzt wurde.
1940 übernimmt die C. Lorenz AG die Schaub Apparatebau-Gesellschaft mbH mit Sitz in Pforzheim-Dillweißenstein.

Nun zu Schaub:

Der Erfinder und Elektropionier 1921 Georg von Schaub gründete in Berlin-Charlottenburg die „Schaub-Elektrizitätsgesellschaft“. Innerhalb von zwei Jahren wurden Detektorempfänger, zunächst noch einfachste Geräte zum Empfang von Hörfunksendungen, entwickelt und produziert.
Ab Oktober 1925 firmierte Schaub als G. Schaub Apparatebau-Gesellschaft mbH.
1928 bagann die Serienproduktion von Überlagerungsempfänger wie den „Superhet U 8“ und ab 1932 eine fortentwickelte Version des Superhets „Super 33“.
Die Firma erreichte einen Gesamtmarktanteil von 4,5 % und spielte fortan in der Liga der großen Hersteller. 1934 wechselte Schaub seinen Betriebsstandort in die aufgelassene Maschinenfabrikhalle in Pforzheim-Dillweißenstein. Die Stadt Pforzheim wurde 1936 Mitgesellschafter.
Um die Entwicklung und Herstellung von Rundfunkempfängern voranzutreiben wurde 1940
die G. Schaub Apparatebau-Gesellschaft mbH von der C. Lorenz AG übernommen.
Eine Fusion der beiden Firmen kam der Wehrmacht sehr gelegen um nun deren dringend benötigten Rüstungsgüter zu fertigen. So wurden ab 1941 keine funktechnischen Geräte mehr für den zivilen Bedarf hergestellt und die Einzelmarke Schaub ging unter.
Fortan wurden in 12 Betriebsstätten mit ca. 24.000 Mitarbeitern aussschliesslich Güter für die Rüstungsindustrie gefertigt. Ein Luftangriff auf Pforzheim am 23. Februar 1945 zerstörte den Industriestandort Dillweißenstein nahezu vollständig.

Nach Kriegsende musste das Unternehmen mit lediglich 50 Mitarbeitern den Wiederaufbau starten.
Die amerikanische Besatzungsmacht erlaubte zunächst nur Reparaturarbeiten an elektrischen Aggregaten, lockerte aber zunehmend die Voraussetzungen, und der wirtschaftliche Aufschwung lies nicht lange auf sich warten. Ab dem Jahr 1946 wurden wieder Rundfunkgeräte für den zivilen Bereich gefertigt und die Belegschaft stieg bis 1949 auf 800 Mitarbeiter.
Die Firma musste auf den restaurierten Standort Schaubs in Pforzheim ausweichen weil Lorenz in West-Berlin mit der Berlin-Blockade zu kämpfen hatte und dadurch der Güterverkehr mit den westlichen Besatzungszonen unterbrochen war.
Man entschied 1950 noch in Pforzheim zu Produzieren und die Verwaltung des Unternehmens nach Stuttgart zu verlegen. Im Juli 1950 fasst Lorenz die Rundfunkproduktion in Stuttgart zusammen.
Ab 1952 wurde das technische Typenprogramm der beiden Firmen zusamengelegt und gliederte den Gesamt-Vertrieb bei Schaub ein. 1955 wurde die Schaub Apparatebau zu einer Abteilung der C. Lorenz AG.

Mitte 1955 trugen die Geräte den Markennamen Schaub-Lorenz. Nur Kofferradios findet man bis 1957 noch unter dem Namen Lorenz.
1958 fusionierten die C. Lorenz AG und die Standard Elektrik AG, ebenfalls ein Unternehmen der Nachrichtentechnik, zur Standard Elektrik Lorenz AG (SEL), eine Tochtergesellschaft der ITT, so das die Firma nun ITT-Schaub-Lorenz hieß.
Auch der Traditionsbetrieb Graetz zählt ab 1961 mit 13 Produktionsstandorten zum Verbund der SEL-Gruppe.
1975 fährt die SEL Verluste von 16 Mio DM ein und bis zu seiner Schließung im Jahr 1978 wurde der Standort Rastatt zum zentralen Rundfunkwerk für die qualitativ hochwertigen Marken von Schaub-Lorenz und Graetz (Fernsehgeräte, Radios, Autoradios, Kassettenrecorder, Weltempfänger und Lautsprecherboxen).
1979 geht das Segment in der "ITT-Audio-Video-Elektronik" auf.

Ende 1986 wurde SEL mit der französischen Compagnie Générale d'Electricité (CGE) und Alcatel verschmolzen.

Anfang 1988 ging die Unterhaltungs-Elektronik-Sparte an den finnischen
Telekommunikationskonzern Nokia.

Carl Lorenz

* 6. Juli 1844 in Hannover; † 20. Dezember 1889 in Berlin Carl Lorenz war ein deutscher Techniker, Erfinder und Industrieller. Leben: Er wurde 1878 in Berlin Teilhaber der Telegraphenbauanstalt und Pendeluhrenfabrik Wilhelm Horn, die ab diesem Zeitpunkt unter dem Namen Horn & Lorenz firmierte. 1880 gründete er eine eigene mechanische Werkstätte, die Morse-Apparate und elektromechanische Geräte für die Eisenbahn produzierte. Nach seinem Tod 1889 führte sein Bruder Alfred Lorenz die Firma weiter, die im selben Jahr von dem Kaufmann Robert Held übernommen wurde. Held war als Unternehmer äußerst erfolgreich, unter seiner Leitung wurde die Firma, die später als C. Lorenz AG firmierte, ein Weltunternehmen. Nach dem Tod von Robert Held wurde 1930 die Aktienmehrheit an die Standard Elektrizitätsgesellschaft (SEG) verkauft, die der amerikanischen Firma International Telephone and Telegraph Company (ITT) gehörte. Die Firma hatte 1930 ca. 2.700 Beschäftigte bei einem Aktienkapital von 9,5 Mill. RM (1931). 1940 übernahm die Lorenz AG die im Jahre 1921 gegründete Firma G. Schaub Apparatebau-Gesellschaft mbH in Pforzheim und firmiert ab 1955 unter Schaub-Lorenz. 1958 wurden die beiden ITT-Töchter Standard Elektrik AG und C. Lorenz AG zur Standard Elektrik Lorenz AG (SEL) zusammengelegt, die mittlerweile in Alcatel-Lucent Deutschland AG umbenannte Firma ist heute Teil des französischen Telekommunikationsausrüsters Alcatel-Lucent.

Die C. Lorenz AG war ein deutsches Unternehmen mit Sitz in Berlin. Geschichte: 1862: Die Telegraphenbauanstalt und Pendeluhrenfabrik Wilhelm Horn wurde in Glashütte gegründet. 1870: Horn ging nach Berlin und gründete dort die Internationale Telegraphenbauanstalt Berlin, die in der Brandenburgstraße 45 ansässig war. 1875: Bis 1875 war Gustav Rhode Leiter der Firma. Die Telegraphenbauanstalt und Pendeluhrenfabrik Wilhelm Horn in Glashütte wurde zur Außenstelle der Internationalen Telegraphenbauanstalt Berlin. In Berlin arbeitet Wilhelm Horn mit Carl Lorenz und dessen jüngerem Bruder Alfred zusammen. Das Berliner Adressbuch aus dem Jahre 1878 nennt Carl Lorenz als Teilhaber der Telegraphenbauanstalt, die zu diesem Zeitpunkt in der Hollmannstraße 35 ist. 1879: wird die Firma im Berliner Adressbuch unter Horn & Lorenz geführt. In der Gründerzeit der Aktiengesellschaften passte die Uhrenfabrik ihren Firmennamen mehrmals den aktuellen Zeitereignissen in Berlin an. Zu den dafür ausschlaggebenden technischen Entwicklungen gehörten u.a. die Einführung des Bogenlichtes im Jahre 1878, die elektrische Eisenbahn im Jahre 1879, die Dochtkohle und die Glühlampe. 1880: Wilhelm Horn erkrankt und musste sich aus dem Unternehmen zurückziehen. Er übergab die Leitung an Lorenz. Damit endeten auch die geschäftlichen Aktivitäten in Glashütte. Carl Lorenz wird jetzt als Inhaber einer Telegraphenbauanstalt, Fabrik für elektrisches Licht, elektrische Eisenbahnen, Kunst und Industrie im Adressbuch von Berlin geführt. Am 1. Juli 1880 bezieht Carl Lorenz eine eigene Werkstatt in der Prinzessinenstr. 21, Quergebäude, III. Stock. Fritz Schlachte ist ihm dabei behilflich. Sein Bruder Alfred Lorenz wird Werkmeister. Felix Büchtemann kommt 1882 als Mechaniker zu dem Unternehmen, daß zu dieser Zeit 15 Gehilfen und 5 Lehrlinge beschäftigen. 1889 20. Dez: Carl Lorenz starb in Berlin an Influenza. Sein Bruder Alfred führte die Fabrik für dessen Witwe und Kinder weiter. 1890: übernahm Robert Held von Lorenz Witwe das Unternehmen. 1908: Neuer Firmenname als C. Lorenz AG. 1908: Erste drahtlose Sendeanlagen für Marine und Heer wurden gebaut. 1909: Einrichtung einer Versuchsfunkstelle in Eberswalde 1917: Umzug in den neuen Sitz in Tempelhof b. Berlin
