Patent DE-2947770-A1 (DE)
Inventor: PANZER KLAUS DR ING
IPC: H04J3/06
Filed: 1979-11-27
Abstract: In a time division multiplex system having chronological grouping of optically transmittable PPM signals, the PPM signals of one half of the time channels are transmitted as pulses in one half of each pulse frame and the PPM signals of the other half of the time channels are transmitted as pulse pauses in the other half of each frame for the purpose of the co-transmission of a clock frequency component without providing a separate synchro time slot. For this purpose, PPM pulses are formed and transmitted only in one pulse frame half, while PPM pulses formed in the other pulse frame half are subtracted from a continuous signal corresponding in amplitude to the pulse amplitude, and the signal difference is transmitted. At the receiver, the frame clock component is filtered out by a band-pass filters and is exploited for controlling a receiving clock generator.

Patent DE-3031567-A1 (DE)
Inventor: KASTENING BERTEL PROF DR
IPC: C23G1/36
Filed: 1980-08-21
Abstract: In addition to catalyzing the reoxidization of spent alkaline etching agent, the suspension of activated carbon powder in the etching solution also increases the speed of etching when the etching solution is recirculated in the etching of printed circuit boards. The ammonium sulfate etching solution is set to a pH of about 9 by the addition of ammonia gas. In the recirculation of the etching solution, a part of the solution can be freed by filtration from suspended carbon particles and passed through the cathode and anode chambers of an electrolysis cell for the recovery of the etched metal by deposition on the cathode. The activated carbon powder for this purpose is calcined before use, at a temperature of between 900 DEG and 1200 DEG  C. in vacuum or in an atmosphere that is inert, reducing, or only slightly oxidizing as in the case of an atmosphere containing carbon dioxide, water vapor or both, in a concentration that does not appreciably oxidize the carbon particles.

Title: Method for using nuclear energy in small power stations with the aid of transformation of nuclear radiation by laser
Inventor: MAYER GERHARD DIPL PHYS
IPC: G21D1/00
Filed: 1981-02-13
Abstract: Nuclear radiation from a pulse-operated nuclear reactor (subcritical in normal operation) is used to excite a laserable gas (CO, CO2). Cooling of the nuclear reactor is performed by the laser gas. The entire arrangement is in a gas-tight, sealed container; the laser light output is led off for use to the outside via gas-tight windows; the heat of the nuclear reactor is led off to the outside via a closed coolant loop. The nuclear energy arrangement is inherently safe, since the fission productivity remains in the closed container. The entire arrangement is selected such that the output of the nuclear energy arrangement can dissipate the afterheat passively by means of surface radiation. The reactivity is selected such that after its time of use the entire container can be reprocessed in suitable central installations. Laser light output is converted via "solar" cells into electrical energy:- the heat of the reactor or of the gas coolant is used for heating or cooling. The entire arrangement is selected such that the installation can be used individually.
