Title: Station identification code generator in telephone system - uses ROM stored 0-9 codes selected by conductor pattern unique to station
Inventor: BAMBACH WOLFGANG DIPL ING
IPC: G07C11/00
Filed: 1980-05-06
Abstract: A microprocessor (MP) sends out the identification code group (Q) in accordance with a conductor pattern (PF) produced on, e.g. a p.c.b. between input lines (Ia,Ib, to IVa,IVb) and four output lines each of which is weighted with two alternative digits dependent on whether it is connected to an 'a' or 'b' line. The address lines (A1 .. An) of the microprocessor cause these inputs to be scanned sequentially, and to apply the corresp. output (on Xo to X4) to a storage unit (ROM) holding the binary equivalents for the numbers 0-9. The pattern for individual stations may be produced on a ceramic substrate in thick film in the form of a complete grid and the non-applicable conductor junctions erased subsequently and the entire package sealed. This gives security against tampering - important when the station identification signal is used for debiting call fees.

Appts. has two-channel input stage having a first channel contg. an analogue-digital converter, this channel receives the image and converts it into coded digital data. The second channel of the input stage is a coder, supplied from a keyboard with alpha-numerical data. These two channels feed a computer stage, which processes the digital data into control signals for the data carrier stage, which produces the actual data carriers for the identity cards. These data carriers are then fed to the card producer. Pref. an output stage incorporated between the outputs of the input stage and the input to the computer stage collects and combines the data coming from the two channels of the input stages. Used for the mass prodn. of identity cards. High prodn. rates can be achieved. By contrast with previous methods, there is no need to produce a model or blank of the final identity card. The first channel can operate independently of the second channel and scan the input image, photograph, finger print or the like by line scan, producing coded digital data. The input of alpha-numerical data to the second channel is carried out simultaneously.

Patent DE-3116740-A1 (DE)
Title: Wave-power generating plant
Inventor: GRAVEMEYER EUGEN
IPC: F03B13/18
Filed: 1981-04-28
Abstract: In said plant, retaining cables that are secured to a support device, constructed underwater, or on an underwater machine shop, are used to retain a hollow body in such a way that the latter can roll freely on the waves of the sea, and its upward movements are led by means of tension cables to units, located underwater, for dynamos for the generation of power, which movements cause the units to rotate (Fig. 1). When the hollow body descends, the tension cables are rewound tightly during idling onto their cable drums by counterweights. Since the hollow body which develops the power for generating current is supported by the water, it can, within the bounds of technical feasibility, be constructed with large dimensions, for example the size of a football pitch. In this case, the guying, the number and strength of the retaining cables, and of the tension cables, as well, must be appropriate for the purpose of withstanding bad weather, as well. The power generation is extremely low on occasions, and then once again  extremely high, and can be led into the public power grid only given special precautions. <IMAGE>
