Patent DE-2740928-A1 (DE)
Title: Tubular fabric washing equipment - has rollers in chambers to give intense washing action at each station
Inventor: DAMBROTH JUERGEN ING GRAD
IPC: D06B3/20
Filed: 1977-09-10
Abstract: The equipment to wash tubular fabrics uses rollers and chambers for the fluid, with linking guide plates for the fluid to pass from one roller section to the next. The effect of the roller rotation in the chamber causes the fluid to be forced through the fabric, under the water level, to give an intense washing action at each roller. The washing action is further effected by the effect of the fabric being squeezed on leaving the roller and being passed to the next station, without allowing the fabric to relax and expand in the air and draw air into the material structure. The system allows a number of washing stations of different natures to be linked together so that the material can pass through continuously and be given a sequence of treatments, in a unit which has a high capacity while occupying little space.
Patent DE-2743089-A1 (DE)
Title: Vehicle anti theft locking system - uses readable card as key with discriminator to control connection of ignition circuit
Inventor: SCHONEBOOM HANS JUERGEN
IPC: B60R25/04
Filed: 1977-09-24
Abstract: The antitheft lock for motor vehicles uses card type keys which ca be readily changed. The card reader can deal with a wide range of card patterns which makes card forgery difficult. The key card(16) has coded digital coding features. On inserting this card into reader(1), the digital features are sensed and electrical signals are generated. These signals are fed into signal discriminator which ensures that the ignition circuit is connected only when the correct card is inserted. A warning signal is generated if the ignition lock is tampered with.

Title: Radio receiver using dipole and ground plane aerials - operates using two channels to receive mono-signals from specified direction
Inventor: ANTON OTTO F
IPC: H04B1/10
Filed: 1977-10-21
Abstract: The receiver, for radio signals, has two channels and employs the different receive characteristics of a ground plane aerial and a dipole aerial. The 2-channel receive circuit may be part of a transceiver or of only a receiver and allows mono radio signals to be heard with the correct direction. The differences are emphasised by using a double aerial (dipole + ground plane aerial) for reception and by employing two channels with appropriate reproduction systems (stereo headphones/loudspeakers).

Patent DE-2752857-A1 (DE)
Title: Channel change circuit for television receivers - derives control signals from line and audio stages if transmission fails
Inventor: HAASE HANS JOACHIM ING GRAD
IPC: H03J9/00
Filed: 1977-11-26
Abstract: The channel change circuit derives one of its control signal from the volume control in the audio stage of the receiver. The noise voltage (when the transmitted carrier is absent) is passed through a bandpass filter and is rectified. It is then fed to a leverl detector. The line synch. pulse is separated and fed to a comparator which is also fed with a line pulse from the deflection circuits. The comparator then delivers a second control signal, if the receiver becomes ynsynchronised when the transmitted synch. is absent. The control signal is used to activate a programme memory using a binary counter and decoder. If the number of channel change pulses exceeds the number of store locations, the receiver is either switched off or into the stand-by mode. The circuit comes into operation after a special switch on the receiver is operated manually.

Title: Valve with control discs - has inlet port of sliding disc outside that of fixed one when shut
Inventor: OBERDOERFER HANS
IPC: F16K3/04
Filed: 1977-12-23
Abstract: The valve works into two or more control discs, being partic. for hot and cold water mixing taps for wash basins, baths etc. A first fixed disc has inlet and outlet ports, and does the second one which slides over it, under the action of a setting bar engaging with it at one end. In the shut position the inlet port (11) of the second disc (10) lies on the side of that (6) of the first one (5) furthest from the centre of the latter, so that the inlet port in the first disc is freed from outside on opening the valve. The design avoids the need for an annular or by-pass passage in the body of the fitting.

Title: Bakery goods cooling system - using stepped evacuation stages in cooling chamber
Inventor: BURGBACHER HELMUT
IPC: A21D15/02
Filed: 1979-01-22
Abstract: Baked articles such as rye bread loaves are reduced from the baking temp. down to the packaging temp. by exposing them in a cooling chamber to a reduced pressure in several stages.
