Patent DE-3909151-A1 (DE)
Title: Wave power installation utilising the kinetic energy of water waves, in particular the energy from horizontal travelling wave motion, for driving generators or pumps
Inventor: HAHN RICHARD
IPC: F03B13/14
Filed: 1989-03-21
Abstract: In the already known wave power machines, the kinetic energy of the sea waves predominantly from the vertical reciprocal motion of the waves is used for the purpose of conversion into consumable energy (current). This possibility requires a complicated mechanical system and can be applied economically only to a restricted extent. The novel wave power installation provides for obtaining the consumable energy from the horizontal travelling motion of the sea waves. This possibility operates according to a simple, tried and tested principle and can be implemented economically on a large scale. The operating principle of the wave power installation is based on the driving (rotary movement) of bladed (bucket) drum type (barrel) wheels, conveyor screws (screw conveyors) or propeller screws by the kinetic energy of the water waves. In order to compensate the waxing and waning wave energy, the drive elements are coupled to torque convertors (flywheels) and are arranged at a spacing and offset in the direction of wave travel. The wave power installation is designed with a variable level and capable of rotating for the purpose of adaptation to the wave level and the wave direction. The aim of the wave power installation is to make use of the gigantic energy potential of sea waves for consumable energy. A single sea wave with a width of 100 m contains a quantity of water of 15000 m<3> in round figures for a moderate sea and has a speed of approx. 12.5 m/sec, which corresponds to a kinetic energy of 1171875 kJ.

Title: Excess temperature protection for electrical fuse - has bimetal temperature sensor with fibre optic signalling of fuse condition and location for triggering corrective action
Inventor: BARDAHL NILS DIPL ING DR
IPC: H01H85/30
Filed: 1989-07-24
Abstract: A temperature sensing and protection system for fuses is arranged to signal excess temperature and fuse location. Activation of appropriate cooling means or ultimate disconnection of the circuit then ensures after a suitable time delay if normal conditions are not restored. The temperature of fuse (S1) in housing (SG) influences the position of bimetal sensor (B) carrying element (P) such that the light path in sender unit (E) travelling via fibre optic cables (L1, L2) to evaluation unit (VE) can be interrupted in gap (US) thus affecting photo-element (F) and triggering protective sequence. USE/ADVANTAGE - In heavy duty high current distribution systems. Ensures reliable fuse operation by limiting temperature rise. Several grouped fuses can be supervised by a single optical cable with remote indication and local visual identification of fuse affected. Electromagnetic or ultrasonic signal transmission is suitable as an alternative. Temperature sensitive optical device can be substituted for bimetal sensor.

Title: Wireless digital telephone system base station emulator - initiates synchronisation for assigning time slots to subscriber station within frame pattern of signal using positive edges
Inventor: KAEWELL JUN JOHN DAVID
IPC: H04M1/72505
Filed: 1990-02-08
Abstract: The system uses a modified subscriber station to act as a simulated or emulated base station. This emulated base station essentially differs from the subscriber station only in being able to initiate the synchronization process, whereas the subscriber unit only acts to scan the RF signals sent out by the emulated base station until it finds the frequency and slot assigned to it. The signal received from one station is separated into high band and low band energy frequencies. The high band energy output is substracted from the low band energy output to obtain a resultant signal, which is stripped of its sign determine only the amplitude. The stripped signal is accentuated while substantially filtering out noise, and fed to a voltage controlled crystal oscillator (VCXO) which provides the timing at the other station.

Patent DE-4016881-A1 (DE)
Title: Fuel injection pump for IC engine
Inventor: DUGDALE SAM WILLIAM
IPC: F02D41/14
Filed: 1990-05-25
Abstract: The fuel pumping appts. supplies fuel to an internal combustion engine and has a throttle controlled by an electromagnetic actuator in response to a demand signal  to determine the amt. of fuel supplied to injectors. An AC dither signal is superimposed on the DC control signal supplied to the actuator. The dither signal is generated by a disc rotatable in timed relationship with the appts. and a sensor which senses the passage of indicia on the disc.  The dither signal minimises the effects of function in the appts.  and is synchronised with operation of the appts. so that the throttle oscillates for an integral number of cycles per cycle of operation of the appts. The dither signal may also be applied to an injection timing member.
