Patent DE-2737230-A1 (DE)
Title: Continuous butter making machine - applying friction heat to cream produced by relatively movable parts
Inventor: SIMON ROGER
IPC: A01J15/12
Filed: 1977-08-18
Abstract: Cream is turned to butter in a continuous butter making machine by exerting a friction on the cream by parts which move relative to each other so that it is heated for the formation of butter globules. The friction is produced in a fixed cylindrical drum in which a conical drum rotates and the cream is introduced at the narrower annulus end. This prevents the squashing of the fat globules which is caused by the heating action of the pegs of conventional machines. The result is a greater density of butter globules and less fat content in the butter-milk.

Title: Voice controlled multiplex signals transmission system - uses as one channel infrequently as possible to allow transmission of synchronisation signals
Inventor: METZGER ERICH DIPL ING
IPC: H04J3/17
Filed: 1977-09-30
Abstract: A maximum specified number of subscriber channels can simultaneously carry out conversations through a smaller number of transmission channels, owing to allocation of a transmission channel to a subscriber only when he actually speaks. Available transmission channels are allocated at the sending side to the actually talking subscriber channels by keeping a specified channel engaged as seldom as possible. When this channel is free, synchronisation signals are transmitted through it to the receiving side. Transmission of synchronisation signals is recognised at the receiving end from continuously transmitted address signals of subscriber channels.

Patent DE-2830151-A1 (DE)
Inventor: GLIMSKI HANNELORE DIPL ING
IPC: H02J13/00
Filed: 1978-07-08
Abstract: A loosely parallel-connected coupling transformer (T) is used to feed audio-frequency signals into a network. For this purpose, a compensating capacitor (C1) is connected to the input and a coupling capacitor (C2) to the output of the circuit. The coupling transformer (T) has an iron core with an air gap which achieves a very high coupling factor of almost one. To compensate for the apparent power requirement of the coupling capacitor (C2), the secondary winding of the transformer (T) is designed so that it can be adjusted, for example by means of a plurality of additional windings. The transformer (T) can be factory-set through connection and counterconnection of these additional windings, which represents a considerable reduction in cost. <IMAGE>
