Title: Telephone exchange with varying subscriber priority - compares dialled call with priority code collected from store
Inventor: LOHMANN LOTHAR ING GRAD
IPC: H04M3/38
Filed: 1978-07-10
Abstract: The telephone exchange can build-up different kinds of connections: There are internal and external connections in PBX's, and there are trunk, international and intercontinental connections. The subscriber stations are entitled to all or only to a part of those connections.

Title: Fuel injection system for internal combustion system - has float operated fuel valve to release vapour and prevent locking of injectors
Inventor: LAUTERBACH HEINZ DIPL ING
IPC: F02M69/30
Filed: 1979-01-23
Abstract: A pump delivers fuel from a tank through a filter to a quantity regulator. An air flow measuring vane in the air intake moves a piston in the regulator to vary the fuel quantity in proportion to the air quantity. The regulator has outlets, each of which supplies a fuel injector immediately upstream of the inlet valve of a cylinder. A recirculating flow from the injectors passes through a float chamber. The outlet of this returns fuel to the excess fuel return int the tank. A float in the chamber opens the outlet to release vapour and so prevent vapour locking of the injectors.

Title: Dumpling preparation - by enclosing dough with liquid in impermeable foil bags before dough raising treatment
Inventor: DURAN VLADIMIR
IPC: A23L5/10
Filed: 1979-03-16
Abstract: Dumplings are prepared by enclosing the dough together with a liquid (water, milk, fat) in a not perforated foil which is impermeable to liquid and compatible with food. The dough raising process can be carried out in boiling water, steam or in an oven or grill. This protects the dumplings through all process stages right up to their consumption. The foil bag protects against loss of substance if the boiling time is exceeded. Power is saved because the dumplings need not merely float but can now fill up the whole water bath.

Title: Photo-electric circuit detecting changes of useful light component - has control circuit with time constant stabilising changes of transducer voltage arising from LF interference and constant light
Inventor: AMMER RUPERT
IPC: G01J1/44
Filed: 1979-04-09
Abstract: A photo-electric arrangement produces an electrical output signal corresp. to changes of intensity of the useful light component of a light signal. The latter contains a relatively large interference light component but of lower frequency than the useful component. Such a light signal is produced in certain plasma-physical experiments in which particles of frozen hydrogen are shot past a light source within a light barrier by means of a high powered, focussed laser beam. A photo-electric transducer (10) receives a rest state-working voltage. An associated circuit has a working resistor (R1) coupled to the transducer. This circuit contains an amplifying stage and delivers a signal free from the lower frequency components of the signal produced by the transducer. The circuit includes a control circuit (A1, A2, R4 to R9, C1) to regulate the working voltage of the transducer.
