Patent DE-2619859-A1 (DE)
Title: Inductive communication transmitter for railways - has temp. raised on switching on by dissipating output in internal load
Inventor: AUKSUTAT GUENTER DIPL ING
IPC: H04B1/04
Filed: 1976-05-03
Abstract: The inductive communications transmitter, for track-side to train communications at very low temperatures (e. g. -30 deg.C), has a switch that switches the transmitter full power (10-25W) through to a load inside the transmitter housing instead of to the inductive antenna. The heat dissipated in the load raises the transmitter temperature to a point where it meets its rated performance figures. The transmitter is then switched to the antenna. The advantage lies in allowing transmitters exposed to very low temperatures to reach their rated performance quickly by raising the temperature of their semiconductor components much faster than would occur with 'normal' warming up.

Title: Synchronisation monitor for communication system - monitors injection synchronised oscillator by detecting mix of input and output signals
Inventor: BUECHS JUST-DIETRICH DR ING
IPC: H03L7/24
Filed: 1976-07-27
Abstract: The synchronisation monitor, for a communications system, contains an injection synchronised oscillator whose input and output signals are mixed using the non-linear part of the active element's characteristics. The product is filtered, amplified and used to indicate the degree of asynchronisation and/or to switch off the oscillator if it starts to free run. The advantage lies in avoiding the condition arising when the input is absent or very small whereby the oscillator starts to oscillate at its natural frequency - a frequency that may be so far removed from the input signal that power is generated in an adjacent channel causing interference.

Patent DE-2731569-A1 (DE)
Title: Radiation treatment of granular material - giving precise dosing without mechanical damage
Inventor: BRUNNER ALFRED DR SC TECHN
IPC: A01C1/00
Filed: 1977-07-13
Abstract: Granular material is subjected to penetrating radiation by means of a conveying drum, a dispensing system and a dosing device. The material flows from the dispensing container onto the surface of the rotating drum. The dosing device restricts the thickness of the layer of granules so that a stream of granules of a constant depth flows on the surface of the drum beneath a radiation device stationed immediately after the dosing device. The dispensing system consists of a silo with, at its lower end a hopper, the back wall of which terminates on the surface of the roller. The height of the front wall is adjustable according to the nature of the granular material so that there is an adequate flow and distribution of material across the surface of the roller. The dosing device may consist either of a roller with a smaller dia. than that of the conveying drum rotating in the same direction as the drum so that its peripheral velocity along the line closest to the drum is less than the forward velocity of the drum surface or of an oscillating beam. The function of each of these devices is to sweep back the material in excess of a the required depth and to prevent bridging. The relative velocities are such as to ensure the continuous net flow of material in the direction of motion of the drum surface. The dispensing device is equipped with a restricting plate at the back of the hopper which bears part of the stati cal pressure of the granules in the silo thereby limiting the feed of granules to the dosing device. The radiation device consists of a radiation gun such as an electron gun which moves backwards and forwards across the surface of the drum so that all of the granules receive a similar dose of radiation. System is used for the radiation treatment of granular material such as the radiation of grain to influence germination.
