Title: Electric coffee maker with furring up indicator - has pressure measuring unit to respond only to high pressure reducing false alarms
Inventor: TRAUNSPURGER GUENTER
IPC: A47J31/057
Filed: 1976-11-17
Abstract: Theelectric coffee maker has a pressure-operated indicator device to indicate the state of furring up wherein a pressure measuring unit is provided with a measuring chamber in which the piston (20), diaphragm or bellows forms a pressure chamber (62) which is connected to the water pipe leading from the fresh water container (3) to the coffee filter as well as a damping chamber (32) which has a throttle opening (34).

Title: Cooler guide for moulding belt in continuous casting - has surface formed by dishes with high pressure nozzles
Inventor: LAUENER WILHELM FRIEDRICH
IPC: B22D11/06
Filed: 1977-06-29
Abstract: The running moulding belt in an installation for casting continuous metal ingots, is cooled and guided by directing a cooling fluid through a large number of nozzles towards the face of the belt turned away from the casting chamber. The jets, under high pressure, open into separate dishes, the rims of which are turned towards the belt, and the flow is adjusted so that the coolant fills the dishes and the space between them and the belt completely. The cooling fluid then flows between the rims of the dishes and the belt to be drained off at low pressure. The outlet cross-section from each dish is determined by spacing between the moulding belt and the rim of the dish. In each dish therefore, a hydrostatic pressure acting on the belt is developed, the degree of which depends upon the spacing mentioned. This pressure together with the low pressure prevailing outside the dishes maintains the moulding belt automatically at a practically constant spacing from the rim of each dish. The moulding belt is thus held in the zone of the casting chamber without being retarded and at the same time is guided positively.

Patent DE-2751417-A1 (DE)
Inventor: UEBEL HELMUT DIPL ING
IPC: G08G1/127
Filed: 1977-11-17
Abstract: In controlling radio communications, problems arise as a result of the same signal transmitted by a vehicle being received simultaneously by a plurality of stationary receivers. To avoid these problems, the phase of the output signal occurring as a square-wave signal in the receiver after passing through a discriminator (D) and a trigger circuit (T) is modulated in an EXCLUSIVE-OR gate (EO) by a clock signal (TF) arriving from the central station. Before being forwarded via a bandpass filter (BP) to the common data line (S), the signal thus obtained is multiplied in a multiplier (M) by a factor which is derived from the level of the input signal. A low-pass filter (TP) and an amplifier (V), which advantageously has a non-linear characteristic, are used for this purpose. This results in a considerable boosting of the signal arriving from the receiver with the highest input level. <IMAGE>
