Patent DE-3014958-A1 (DE)
Title: Fuel injector IC engine - has needle valve shaped to avoid wear effects on seat dia.
Inventor: KINZEL RICHARD DIPL ING
IPC: F02M61/18
Filed: 1980-04-18
Abstract: The fuel injection nozzle is used in an IC engine. It has a needle valve which opens at a differential pressure determined by the spring pressure and the dia. (25) of the conical needle seat. Due to wear in the needle and the seat, the effective sealing dia. of the valve changes so that the nozzle opening pressure also alters. The changes in the effective sealing dia. of the valve are avoided by suitably shaping the tip of the needle (22), such as by providing a seating surface (23) in the form of a frustrum of a cone. Other shapes can also be used.

Patent DE-3019457-A1 (DE)
Title: Animal identification and estrus detection system - has computer control providing printer output of animal identity and number of movements from transponder on animal
Inventor: RODRIAN JAMES A
IPC: A01K11/00
Filed: 1980-05-21
Abstract: An animal such as a dairy cow carries a transponder unit which includes a motion sensor. When the animal comes within range of a transceiver unit, the transponder unit is interrogated and the unit transmits data which identifies the animal and indicates the number of movements of the animal. The number of animal movements increase dramatically during estrus when this occurs. Data received at the transceiver is processed by a microprocessor based system which operates to insure the received data is correct. It also assembles the data and outputs it to a printer.
Patent DE-3020868-A1 (DE)
Title: Ignition system for IC engine - displaces ignition point for matching to knocking by loading output of inductive ignition-point generator
Inventor: FRITZ ADOLF R
IPC: F02P5/155
Filed: 1980-06-02
Abstract: The inductive ignition-point generator (10) is loaded so as to shift the ignition point in order to, e.g. match to a given engine-knocking limit. Loading occurs during the hold time of a timing circuit (25) whose hold time can be shifted by a second timing circuit (24) w.r.t. a periodic marker, e.g. the ignition point. Loading occurs only during one half wave of the generator's output signal. Further timing circuits can be used to load the generator's output during further time intervals in order to optimise matching to given characteristics, e.g. different knocking limits. The generator controls an electronic switch (15) in the primary circuit of the ignition coil (16). The output of the electronic switch may be coupled to the input of the first timing, whose output in turn controls a transistor switch (21) that connects a load to the output of the generator. The timing circuits consist of digital counters. A rectifier diode (20) ensures that loading occurs only during one halfwaye. The advantage lies in the simple manner in which the ignition point is displaced.

Title: Colour photograph prodn. from black and white original - by making separate coloured copies on film and recopying on single substrate
Inventor: SCHRADER HELMUT
IPC: G03C11/18
Filed: 1980-07-16
Abstract: Colour photographic prodn. from black and white originals involves giving the linear, areas and characters the desired colour, using at least 2 reproduction films, and then copying all the individual colour information on a single substrate. A black and white negative is prepd. and positive film(s) is/are made from this. The individual coloured copies are made and then copied together and colour developed. Black is converted to white lines by exposure with a reproduction negative. The film and paper have highly accurate alignment holes. The process uses relatively little time and material and gives a colour diapositive or paper with as good sharpness and colour brilliance as a full colour print.

Title: CMI coder for digital transmission system - uses flip=flops and NOR and OR logic gates
Inventor: MUELLER HORST DIPL ING
IPC: H04L25/49
Filed: 1980-09-04
Abstract: The CMI coder for a digital transmission system uses a D-type flip-flop with its D input coupled to the coder input and its Q output coupled to the J and K inputs of a JK type flip-flop. The second output of the first flip-flop is coupled to a NOR gate also receiving the Q output of the second flip-flp. A second D type flip-flop receives the output of the NOR gate with its Q output fed to a second NOR gate coupled to the coder output via an OR gate.
