Title: Inverter circuit for driving rotary field machine - has switching choke for each DC regulating unit split into three partial chokes
Inventor: RASEK WERNER DIPL ING DR
IPC: H02M7/515
Filed: 1976-09-27
Abstract: Inverter circuit comprises an n-phase inverter connected to a load, such as rotary-field machine, and having controlled rectifiers such as thyristors in a bridge circuit. The circuit provides high output frequencies, without high circuitry costs being involved, and commutation switching is independent of the load. The switching choke of each d.c. regulating unit is divided up into three partial chokes, the first partial choke or coil being of sufficient inductance to limit the current and together with the third partial choke, to change the charging of the switching capacitor, via the triggered main thyristor. The second partial choke has an inductance together with that of the first partial choke sufficient for the resetting of the circuit with regard to the state of the main thyristor, the second partial choke being arranged in the resetting circuit outside the d.c. regulating unit. Initial charging of the switching capacitor(s) occurs via the associated charging resistor(s).

Title: Gantry crane cable truck equipment - uses linear motors with pole pitches and grooves to suit garland positions
Inventor: POPPENHUSEN CONRAD DIPL ING
IPC: B66C13/12
Filed: 1978-06-10
Abstract: The gantry crane has trucks supporting a cable garland and driven by linear motors supplied by a travel direction switch on the crab or at the driving position via a single thyristor-controlled inverter with a common adjustable voltage and frequency. Speed and acceleration of all trucks is stepped to suit their positions in the garland and they are kept at regular intervals. Frequency and voltage are raised proportional to speed for all motors, to give sufficient thrust. Using an inverter which can be set down to very low frequencies, the pole pitches and the number of grooves per pole of the motors of the individual trucks are arranged in accordance with their sequence in the garland. The same section of sheet metal is used with differing numbers of turns. The rated frequency at the inverter output ensures the desired maximum speed of the fastest truck with a minimum groove pitch of 1cm. approximately.

Title: Filter system to monitor plankton content of water - uses 10-20 micron mesh band with coarse mesh sheet cover sandwiched between transparent protective sheets after band leaves filter section
Inventor: KROEBEL WERNER PROF DR
IPC: G01N33/18
Filed: 1978-10-02
Abstract: Filter to remove plankton from water stream involves pumping the water down a duct. Across the duct in convex profile to the direction of flow is stretched a filter medium of 10-20 mu pore size. This is on a roll and can be moved continuously or stepwise across the duct. An overlay of coarse mesh is laid on top of it. When it leaves on the other side of the duct it is sandwiched between two sheets of a transparent protective e.g. plastic sheet. The resulting band is then coiled onto a roll. The drives are interlinked so that all move at the correct speed. Used for measuring and monitoring the plankton content of fresh and sea waters. Arrangement allows the measurements to be made quickly and continuously so that the factors which control plankton growth can be studied.

Title: Identifying and blocking system for telephone party line - uses relays controlled by operational amplifier and reset relay
Inventor: SIEMSSEN HORST-UWE ING GRAD
IPC: H04Q3/48
Filed: 1978-12-14
Abstract: The marking circuit indicates if a party line connected to is in use, and blocks the operation of a second subscriber appts. in such a case. An operational amplifier (V1, V2) is connected by its non-inverting input (+) to a positive volt. (U) and, over the marking contact (T1, T2), to a zero or negative ref. The inverting inputs (-) of all the amplifiers (V1, V2) are commoned. This common circuit is fed from the output of a further amplifier (V6) which has three selectable ref. inputs (U, e1, e2). The highest (U) causes the marking and blocking relay (A1, A2) to pick up when the appropriate selector marking contact (T1, T2) is operated. The other volts. (e1, e2) are lower, and represent a hold on for the relay which also prevents any other circuit from breaking in, and a reset for the relay. The last is the lowest volt. The reset is transiently applied when the handset is replaced.

Title: Program and data organisation in digital telephone exchange - uses hierarchy of stores to simplify entering new routines for new equipment types
Inventor: ROCKINGER FRANZ DIPL ING
IPC: H04Q3/545
Filed: 1979-06-07
Abstract: In a computer controlled telephone exchange, programs and data are held in a hierarchy of stores. The basic program is held in a store (GPSp) divided into distinct sections (SSt1-x) To call up a routine, the program addresses a store (VSp) which contains the addresses (Zal-x) of the working program (PLMl-x) and necessary data (OLM1-x in two further stores (EPSp,EDSp). A particular set of data may apply to more than one working program. The last statement in each working program returns control to the basic program. New routines for new types of equipment can be introduced by making additions to the address, working program and data stores without having to re-write the basic program.
