Title: Hydrostatic pressure monitor with electric circuit - uses pressure-sensitive semiconductor element combined with further element with similar temp. characteristic
Inventor: GERMER WILFRIED DIPL PHYS
IPC: G01L9/00
Filed: 1978-07-21
Abstract: The hydrostatic pressure monitor gives a direct read-out and it uses at least one pressure-sensitive semiconductor element, the electrical resistance of which provides a direct indication of the pressure. The pressure-sensitive semiconductor element is combined with a further semiconductor element which is unaffected by the pressure, but which has the same temp/resistance characteristic, to provide zero compensation.

Title: Screen of VDU with fields subdivided in 7 by 9 matrix - reduces storage needs and has two stores for symbol addresses of rows for interrogation generator
Inventor: HORNUNG MANFRED ING GRAD
IPC: G09G5/24
Filed: 1978-11-02
Abstract: A symbols display system in a visual display unit has the screen divided into separate symbols fields. Each field is subdivided into a seven by nine dot matrix. This reduces the storage capacity required. The address of a symbol is transmitted to two stores, one of which contains the first seven addresses of symbols in the rows for all symbol fields. The second store contains the other rows of all the symbol fields. The two stores are interrogated by symbol addresses and symbol row addresses. The stores are connected in parallel to a symbols generator which supplies the symbols addresses. The row addresses of the symbol control the first store and the second store transmit the rows of all symbols at a common data output.

Title: Compensator for cross-talk between multi-track record and replay head - is effected by superimposing onto replay current, correction current derived from record current
Inventor: KUTZNER REINHARD DIPL ING
IPC: G11B5/027
Filed: 1979-02-23
Abstract: The crosstalk compensator derives a correction current from the current flowing in the recod head and superimposes it onto the current in the replay head. The correction current is derived using an active network between the record head and the replay head. The correction current is prod. by a current source controlled by a signal obtd. from the record head. Current components from a circuit connected to the output of the replay head are substraced from the correction current. The active network is frequency dependent and contains RC components to attain given amplitude and phse characteristics. The active network has a non-inverting amplifier (20) with frequency dependent feedback (25-30) whose input is coupled via two high-pass filters (15-18) to the record head and whose output delivers the correction current.
Patent DE-2907432-A1 (DE)
Title: Pump for washing machine or dish washer - has periphery of impeller backplate curved radially inwards to reduce forces on shaft
Inventor: WISTINGHAUSEN WALTER ING GRAD
IPC: A47L15/42
Filed: 1979-02-26
Abstract: The pump impeller has a hub (2) which fits over the end of the driving shaft. A backplate (5) extends as a flange from the hub. Four radial blades (4) project axially forward from the backplate and extend radially outwards from the hub. The backplate extends outwards as far as the tip of each blade. Between the blades its periphery runs in a straight line from blade to blade or is curved inward slightly towards the hub. This reduces the material and weight of the backplate and reduces the axial force on the hub and shaft.

A spring holds the vale body (25) when unpressurised in a position opening the inlet seat. The body can be thrust by a spring (17), acting against it, into the position shutting the vent, while a further spring (21) supported in the housing (1) acts against the other side of the piston (1), keeping the inlet open.

Title: Radio controlled door lock for vehicle - has key transmitting PCM signals to receiver in lock containing demodulator and code comparator
Inventor: KRONENBERG HARTMUT
IPC: G07C9/00
Filed: 1979-03-26
Abstract: The door lock has a receiver to receive electromagnetic signals sent by a small transmitter acting as door key and carried by the driver. The transmitter's signal is modulated with a code specific to the lock or lock assigned to the transmitter. The received signal is demodulated and the received code compared with a stored code. If the two codes are the same the lock is released and the door can be opened. Pulse code modulation is used, and the transmitted signal has a frequency in the MHz or GHz region, or it may be infrared radiation. The advantage lies in simplicity -- i.e. in avoiding the numerous mechanical parts needed in a conventional lock.

A picture changing mechanism consists of a slide movable to-and-fro parallel to the window, a driver for individual pictures and a driver for the remaining stack. One driver is mounted on the case, and the other on the slide. When the slide moves in one direction, it removes a picture, and when it is pushed back, it reinserts the picture at the other end of the stack. The picture changing mechanism has an element for the picture moving, controlled by the slide movement and temporarily connected with the picture side facing away from the stack.

Title: Microprocessor controlled heterodyne receiver - has two mixers fed by tunable frequency selective front end input stage
Inventor: HENZE WERNER
IPC: H04B1/26
Filed: 1979-04-21

The oscillator forms part of the control unit and its frequency is fed to the mixer stage. The control input of the tunable and frequency selective front and input stage is connected to the control unit through the D/A converter. The h.f. signal from the aerial is transmitted to the front end input stage which feeds the first mixer providing the i.f. signal for the second mixer. The digital control unit includes an outside microprocessor and memory with data conversion ensured by a frequency synthesiser.

Patent DE-2924010-A1 (DE)
Title: DC coupled diode connected amplifier stages - with active element associated with diodes to reduce their surface area on integrated circuit chip
Inventor: KRAUSE GERHARD
IPC: H03H11/00
Filed: 1979-06-13
Abstract: The application is to dc coupled amplifiers with the interconnection made through current carrying diodes. The resistance of the diodes has to be small compared with the input resistance of the subsequent amplifier stage. To enable the satisfactory manufacture of such an amplifier on an integrated circuit chip, an active coupling circuit is required. The first stage amplifier (T1) is coupled to the second (T6) through a diode chain (D1-Dn) which is connected between the input and gate terminals of a FET (T3). The FET output connects to the gate of the second stage (T6). A further transistor (T4) is connected as current source between the gate end of the diode chain and the supply. It is also desirable to connect a similar source (T5) to the second stage gate. The connection permits the use of diodes (U1-Dn)with much reduced surface area than would be necessary without the active element (T3). The design and manufacture of the circuit in integrated form is thus easier.

Title: Positioning system for pipe-laying ships - uses winches and electric motor driven propellers to eliminate rocking motion of ship
Inventor: SCHNEIDER LUISE
IPC: F16L1/20
Filed: 1979-09-06
Abstract: The positioning system for ships laying pipes in deep water controls the winches that hoise the ship's anchor cables such that the ship moves in the reouired direction. A compensation force is exerted on the ship by the winches by driving in conjunction with the forces produced by the winches. The course, direction and magnitude of the compensation force is controlled by electric propellors in conjunction with the forces produced by the winches such that the resulting force acts against the central elastic force and the oscillating motion of the ship is nullified. The positioning propellers are driven by electric motors.

Title: Traffic-light signalling system for road junctions - has time matrix storing times between opposing streams of traffic
Inventor: BRUNNER HEINRICH DIPL ING
IPC: G08G1/097
Filed: 1979-09-24
Abstract: A time matrix stores data describing the times between two opposing streams of traffic. Rational setting signals for the signal generators are produced based on actual spatial times. Only those data describing times between opposing streams of traffic are used that are contained in the time matrix in order to generate the setting signals for the signal generators. The greatest approach time for the relevant approach signal group is reduced by one second in value. This has the advantage of being able to retain time values relating to seconds in the time matrix, which means simpler processing of the values in the time matrix.
