Patent DE-2339696-A1 (DE)
Title: Study of sinking of solid material particles - with photometric method of measuring cloudiness and settling time of solid material particles in a liquid
Inventor: BERANEK KONRAD DIPL-PHYS
IPC: G01N21/27
Filed: 1973-08-06
Abstract: Cloudiness in a liquid is measured in relation to time in several vertical positions within a fluid column, where at start of the measurement the "solid material particles" (SMP) take up a position ready for sinking. The SMPs are injected disturbance free into the liquid so that they are evenly distributed and a comparison is made between cloudiness of a known SMP with that on test. The rate of change of the cloudiness is converted into an electrical signal for easier comparison with that of a known material. Further rate of change of cloudiness is determined by extrapolation. The container is so high that sinking of SMPs takes place over a distance sufficient for optic and cloudiness metering. Servodrives are used to keep cloudiness the same.

Title: Direction-finding aerial system without metallic interconnections - uses modulated monochromatic light through glass-fibre lines and localised power supplies
Inventor: WAECHTLER MAXIMILIAN DR
IPC: H04B10/2575
Filed: 1973-11-02
Abstract: The direction finding aerial system with locally distributed individual aerials has an electro-optical modulator on each aerial and the modulated monochromatic light from the modulator is fed through metal free glass fibre lines to a central station at which the received light is demodulated back to electrical signals and calculates the angle of bearing. Laser diodes are used in the known way as transmitters and photodiodes are used for the reception. Metallic lines for the power supply to the direction finding aerial system are also avoided by providing each power using location with its own local power source in the form of long life batteries. In this way back radiation errors are completely avoided.

Patent DE-2360625-A1 (DE)
Title: Overcurrent protection for current regulators - has diode taking extra current instead of protective transistor switch at excessive overcurrents
Inventor: REITER HERBERT
IPC: H02H7/00
Filed: 1973-12-05
Abstract: The overcurrent protection circuit for current regulators has a transistor switch coupled by its base to a two-resistor voltage divider loading the supply. The transistor collector is connected over a diode to the positive supply pole. When the current from the supply rises sufficiently the voltage drop across one resistor reaches the base-emitter voltage required to turn on the transistor. If the current rises still further, the second resistor ensures that the diode carries the greater part of this extra current. The same result may be achieved by bridging the transistor base-emitter junction by another transistor base-collector junction.

Title: Plate heat exchange with flow channel depressions - has depressions formed by chemical erosion and plates are glued together
Inventor: TRAUTZSCH GOTTFRIED
IPC: B23P15/26
Filed: 1974-02-06
Abstract: Before the chemical erosion process, the plates are covered photochemically by a discontinuous protective film. The location of the discontinuities corresponds to that of the depressions which are to be formed in the plate surface. The discontinuities are created by mechanically removing the film after its deposition, and after the erosion process the plates are joined together by e.g. glue or solder. In the latter case, the solder is placed in position before production of the depressions. The assembled heat exchanger comprises the connected plates which are glued to two end plates to form a liquid-tight box.
Patent DE-2408764-A1 (DE)
Title: Constant speed control for car - has servo system to automatically hold speed at previous manually controlled speed
Inventor: SCHMALL KARL-HEINZ
IPC: B60K31/00
Filed: 1974-02-23
Abstract: The constant speed control comprises a reference servo and a servo which follows the actual speed of the vehicle. A comparing circuit compares the two values and with a feedback loop controls the motor fuel supply to regulate the actual speed to the reference speed. A selector switch changes the system from automatic to manual control. When the system is in manual control the reference speed servo is locked to the actual speed servo, so that when automatic is selected the reference speed is set at the last actual value attained. This relieves the driver from having to set the control for the speed manually, and enables him to retain full concentration on his driving.
