Title: Flashing light warning system for household equipment - has indicator lamp flashing at fixed rate and period determined by multivibrator circuit
Inventor: SCHOTTEN HENNO DIPL ING
IPC: G08B5/36
Filed: 1976-12-18
Abstract: A flashing light warning system for use with household electrical electrical equipment, e.g. refrigerators is constructed using a multivibrator circuit.

Title: Seat belt for three point fixing - has lock clasp actuating electric switch which carries on blocking of retractor
Inventor: GUETTLER HERMANN
IPC: B60R22/343
Filed: 1977-01-19

Title: Hygienic device for determining the contents of excreta - comprises a transparent container contg. an absorbent carrier impregnated with indicators and sealed by a sample tube
Inventor: EIGLMEIER KURT DR
IPC: B01L3/14
Filed: 1977-06-29
Abstract: The parent patent described a device for measuring the occult blood in human or animal excretions, esp. faeces. The device comprised to closable transparent container with a stopper to which a sample tube, open on two sides, was attached. When the device was closed this tube reached to the bottom of the container where an absorbent carrier, impregnated with chemical indicators, was positioned. Alternatively, this absorbent carrier was on the walls of the container or attached to the sample tube. In this addition the absorbent carrier is impregnated with chemical indicators specific to various components of the faeces. The device can be used to determine the presence of protein, bilimbin, urobilinogen and fat in the faeces and to determine the pH of the faeces. It can also determine the contents of other excreta such as the meconium and vomit. The device reduces the contact that laboratory workers must have with the excrement; it is therefore more hygienic than previous methods.

Title: Magnetic coupling for IC engine driving heat pump - displaces poles to reduce required starting torque
Inventor: DIETRICH ROLF DIPL PHYS
IPC: F02N15/02
Filed: 1979-03-21
Abstract: An i.c. engine driving a pump through a magnetic coupling may not, at starting, develop sufficient torque. To assist starting the magnet rings of the drivin and driven halves are circumferentially displaced just before the start so that the magnetic force set up produces a torque which will assist the motor. This displacement is in the direction opposite to the normal rotation. the movement may be made with a hydraulic actuator. The air gap between the two pole systems may contain a non-magnetic bell housing to seal the operating fluid of the pump rom the motor casing. This prevents mixing of the fluid with the motor fuel as combustion products from the fluid an be toxic, and their presence in the exhaust gases therefore undesirable.
Patent DE-2911297-A1 (DE)
Title: Synchronisation fault location in PCM telephone exchange - reports diagnosis of line or exchange fault to controller using resetting loop
Inventor: BINZ REINER DIPL ING
IPC: H04L7/00
Filed: 1979-03-22
Abstract: Loss of block synchronisation by a connection unit of a time-multiplex PCM telephone exchange, initiates an automatic routine to diagnose the fault location. First the output is looped back to the input, and the synchroniser is reset and the units sends all 'ls' as a fault signal. If synchronisation is still lost, the connection unit is faulty. This fact is reported to and stored by the exchange controller. If synchronisation is recovered, the fault is incoming. A unit receiving a fault signal proceeds to check itself. If the test fails it reports itself faulty to the exchange controller, if not, it reports the line faulty.
