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.

Many contemporary "televisions" (more correctly named as displays) would not have this level of staying power, many would ware out or require major services within just five years or less and of course, there is that perennial bug bear of planned obsolescence where components are deliberately designed to fail and, or manufactured with limited edition specificities..... and without considering........picture......sound........quality........

..............The bitterness of poor quality is remembered long after the sweetness of todays funny gadgets low price has faded from memory........ . . . . . .....
Don't forget the past, the end of the world is upon us! Pretty soon it will all turn to dust!

SIEMENS BILDMEISTER FC524 (7 667 279) YEAR 1977.







The SIEMENS BILDMEISTER  FC524 (7 667 279) is  A comfortable 22 inches color television set with 16 programs and VST Motorola memotronic search tuning system and the fine tuning was shiftable with a middle point potentiometer.
Ultrasonic remote control is featured.
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 should also be understood that the use of this invention is not intended to be restricted to a television set, but can be utilized for the control of a large variety of other kinds of apparatus, e.g. door locks, household appliances, radio receivers, production machinery, etc. While the description below will be directed to a wireless ultrasonic transmitter-receiver system, it should be understood that a wired system, a radio control system, etc. could be used in the alternative.
The advantages of the invention are obtained by the provision of a system including means for receiving a transmitted signal comprising a pulse envelope modulated continuous wave ultrasonic signal at a first predetermined frequency, each pulse being immediately followed by a continuous wave ultrasonic signal at a second predetermined frequency which has amplitude such as to mask echoes of the first predetermined frequency at the receiving means, the pulses being representative of a sequence of binary bits, means to determine whether the received signal is above or below the frequency of a reference frequency, means for recognizing a change in input frequency with respect to the reference frequency, and means for counting said changes, determining the value of the binary bits, and providing a parallel coded signal representative of said value.


This models series was introducing the FIRST VERSION OF FM100 modular chassis phasing out all previous models series using the earlyer chassis types.

Also using the P.I.L. RCA CRT TUBE FAMILY already used by SIEMENS IN PREVIOUS SERIES.




























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.

Making its presence for the first time in Tamil Nadu, these technologies allow highly accurate and early diagnosis of all kinds of ailments, thus aiding precise treatment.

Founder generation

Siemens & Halske was founded by Werner von Siemens on 12 October 1847. Based on the telegraph, his invention used a needle to point to the sequence of letters, instead of using Morse code. The company, then called Telegraphen-Bauanstalt von Siemens & Halske, opened its first workshop on October 12.
In 1848, the company built the first long-distance telegraph line in Europe; 500 km from Berlin to Frankfurt am Main. In 1850 the founder's younger brother, Carl Wilhelm Siemens started to represent the company in London. In the 1850s, the company was involved in building long distance telegraph networks in Russia. In 1855, a company branch headed by another brother, Carl Heinrich von Siemens, opened in St Petersburg, Russia. In 1867, Siemens completed the monumental Indo-European (Calcutta to London) telegraph line.
In 1881, a Siemens AC Alternator driven by a watermill was used to power the world's first electric street lighting in the town of Godalming, United Kingdom. The company continued to grow and diversified into electric trains and light bulbs. In 1890, the founder retired and left the company to his brother Carl and sons Arnold and Wilhelm.

Turn of the century

Siemens & Halske (S&H) was incorporated in 1897, and then merged parts of its activities with Schuckert &; Co., Nuremberg in 1903 to become Siemens-Schuckert.
In 1907 Siemens (Siemens & Halske and Siemens-Schuckert) had 34,324 employees and was the seventh-largest company in the German empire by number of employees. (see List of German companies by employees in 1907)
In 1919, S&H and two other companies jointly formed the Osram lightbulb company. A Japanese subsidiary was established in 1923.
During the 1920s and 1930s, S&H started to manufacture radios, television sets, and electron microscopes.
In 1932, Reiniger, Gebbert & Schall (Erlangen), Phönix AG (Rudolstadt) and Siemens-Reiniger-Veifa mbH (Berlin) merged to form the Siemens-Reiniger-Werke AG (SRW), the third of the so-called parent companies that merged in 1966 to form the present-day Siemens AG.
In the 1930s Siemens constructed the Ardnacrusha Hydro Power station on the River ShannonIrish Free State, and it was a world first for its design. The company is remembered for its desire to raise the wages of its under-paid workers only to be overruled by the Cumann na nGaedheal government. in the then


World War II era

Preceding World War II, Siemens was involved in funding the rise of the Nazi Party and the secret rearmament of Germany. During the second World War, Siemens supported the Hitlerconcentration camps to build electric switches for military uses. In one example, almost 100,000 men and women from Auschwitz worked in a Siemens factory inside the camp, supplying the electricity to the camp. regime, contributed to the war effort and participated in the "Nazification" of the economy. Siemens had many factories in and around notorious
Siemens businessman and Nazi Party member John Rabe is credited with saving hundreds of thousands of Chinese lives during the Nanking Massacre. He later toured Germany lecturing on the atrocities committed in Nanking.
In the 1950s and from their new base in Bavaria, S;H started to manufacture computers, semiconductor devices, washing machines, and pacemakers.
In 1966, Siemens &;; Halske (S&H, founded in 1847), Siemens-Schuckertwerke (SSW, founded in 1903) and Siemens-Reiniger-Werke (SRW, founded in 1932) merged to form Siemens AG.
In 1969, Siemens formed Kraftwerk Union with AEG by pooling their nuclear power businesses.
The company's first digital telephone exchange was produced in 1980. In 1988 Siemens and GECPlessey. Plessey's holdings were split, and Siemens took over the avionics, radar and traffic control businesses — as Siemens Plessey. acquired the UK defence and technology company
In 1985 Siemens bought Allis-Chalmers' interest in the partnership company Siemens-Allis (formed 1978) which supplied electrical control equipment. It was incorporated into Siemens' Energy and Automation division.
In 1987, Siemens reintegrated Kraftwerk Union, the unit overseeing nuclear power business.
In 1991, Siemens acquired Nixdorf Computer AG and renamed it Siemens Nixdorf Informationssysteme AG, in order to produce personal computers.
In October 1991, Siemens acquired the Industrial Systems Division of Texas Instruments, Inc, based in Johnson City, Tennessee. This division was organized as Siemens Industrial Automation, Inc., and was later absorbed by Siemens Energy and Automation, Inc.
In 1997 Siemens agreed to sell the defence arm of Siemens Plessey to British Aerospace (BAe) and a German aerospace company, DaimlerChrysler Aerospace. BAe and DASA acquired the British and German divisions of the operation respectively.
In 1999, Siemens' semiconductor operations were spun off into a new company known as Infineon Technologies. Also, Siemens Nixdorf Informationssysteme AG formed part of Fujitsu Siemens Computers AG in that year. The retail banking technology group became Wincor Nixdorf.

In 2000 Shared Medical Systems Corporation was acquired by the Siemens' Medical Engineering Group, eventually becoming part of Siemens Medical Solutions.
Also in 2000 Atecs-Mannesman was acquired by Siemens, The sale was finalised in April 2001 with 50% of the shares acquired, acquisition, Mannesmann VDO AG merged into Siemens Automotive forming Siemens VDO Automotive AG, Atecs Mannesmann Dematic SystemsMannesmann Demag Delaval merged into the Power Generation division of Siemens AG Other parts of the company were acquired by Robert Bosch GmbH at the same time. merged into Siemens Production and Logistics forming Siemens Dematic AG,
In 2001 Chemtech Group of Brazil was incorporated into the Siemens Group, the company provides industrial process optimisation, consultancy and other engineering services
Also in 2001, Siemens formed joint venture Framatome with Areva SA of France by merging much of their nuclear businesses.
