Patent DE-2927401-A1 (DE)
Title: Multicore cable conductor separating and sorting process - arranging cores in prescribed sequence for subsequent connection to terminal blocks or couplers
Inventor: EDINGER EGON
IPC: H01R43/28
Filed: 1979-07-06
Abstract: The process allows automatic or semi-automatic termination and connection of multicore cables. When the cable sheath has been removed the cores are untwisted and laid out on a flat surface, each core touching the next. At this stage the sequence of the cores is arbitrary. In the ensuing stage each core is separated from its neighbour, e.g. by a series of prongs, and a set distance between cores determined. The spacing is maintained by a guide or former, e.g. in the shape of a comb. The actual sequence of cores is then compared with the required sequence. To obtain the correct ordering a second comb is moved transversely over the first, and is positioned successively over the fixed comb so that cores can be lifted from the latter and placed in correct sequence. Both combs have the same spacing. When all the cores are arranged in their correct order they are dropped back into the stationary comb. The next operation can then follow, e.g. stripping the core ends and attaching terminals.

Title: Conversion of waste animal hair to fertiliser - using Wolf machine to segregate off waste and then milling waste finely to give nitrogen rich spreadable fertiliser
Inventor: HOELZMUELLER ROTRAUD
IPC: C05F1/00
Filed: 1979-10-01
Abstract: Waste animal hair is first segregated and opened up in a "wolf" sorting machine to classify it into waste and reusable hair. The waste hair is then collected in a conveyor and sepd. in a cyclone. This hair is fed forward into a grinding machine and milled to fine spreadable clippings. The clippings are then extracted from the grinding machine by an air stream which flows through the machine. The prod. is collected by a further cyclone and bagged. The process is esp. for use on the waste hair from brush factories where reusable waste can be outsorted and the rest processed. It can also be used on the summer hair from carcasses in abbattoirs. The process provides an economic means of converting the waste hair to a usable fertiliser.

Filed: 1979-10-17
Abstract: The microprocessor contains an interpreter memory (5), to hold a set of commands in a lower programming language, and a user-program memory (4) to hold the statements of a user program in a higher programming language. An interpreter controls the processing of user-program statements in the higher language using sequences of commands in the lower language. A permanent memory (7) holds the addresses for the interpreter and its inputs are connected to those lines of the databus (1) occupied by the operation code of the higher language. The permanent memory's outputs are connected to the data inputs of a transfer memory (8).. Multiprogramming branches are realised more quickly by using a lower programming language to interpret a higher programming language.
Patent DE-2944130-A1 (DE)
Title: Water heater and boiler - keeps temp. constant using steam pressure and condensation to control water level on heating plate
Inventor: MAKSELON HENRY
IPC: F24H1/10
Filed: 1979-11-02
Abstract: The water heater and boiler has an electrical heating plate mounted on an insulating pipe. The pipe passes axially down inside a first container and is connected at its lower end to a reservoir and also has a hole at this end. Water flows through the hole into the container and is heated by the plate and converted into steam. The steam pressure increases and keeps the water level in the container at a given place along the heating plate. The steam heats a heat-exchanger at the top of the container and heats the water in that exchanger. When water is run off through the tap, the water in the exchanger cools, the steam in the container condenses and the water level rises to cover more of the heating plate. The temp. of the water is thereby kept constant.

Title: Signal level shifter integrated circuit - has negative conductive, highly-doped layer conductively coupled to emitter of input transistor
Inventor: WILHELM WILHELM DR ING
IPC: H01L27/07
Filed: 1980-02-19
Abstract: This integrated circuit shifts a signal voltage level without changing its amplitude as may be required, e.g. in order to make the signal TTL-compatible. The distributed capacities thus introduced, far from degrading the signal, are arranged to improve the pulse edge. The output of emitter follower transistor (T1) via a resistor (R) and a constant current source (K) provides the level shifted signal. Distributed capacity (C1) is short circuited resulting in another capacitor (C2) bridging the resistor (R) and improving pulse shape.

Title: Complete loop data transmission network - each terminal having fault localisation and restoration switching to adopt end mode if intermediate line fails
Inventor: TAKEZOE FUMIHIKO
IPC: H04L12/437
Filed: 1980-03-31
Abstract: The multipoint data transmission network comprises several terminal units each with a fault diagnosis and restoration switching capability. Each terminal comprises a transmission and reception data unit and associated diagnostic restoration circuit. In line failure cases the fault recognising terminals locate the fault and switch the terminals either end of it to 'end operation' mode, this isolates the faulty line and maintains full terminal operation via a loop path. The fault condition and location are indicated by alarms. The network is proved and the fault conditions determined by using test signals from a generator in the terminal transmission units. A typical network (10) would have a ring formation of transmission lines (12) together with a feedback or loop path (14) for the connection of several terminals (here 3, 16, 18, 20). Each terminal has a transmitter/receiver (22) and line changeover switching (24, 26) together with line matching terminations (28, 30).

Title: Turbine rotor drive without axial bearings - uses helical gears with layshafts equally spaced around drive axis,reducing axial forces
Inventor: FISKER JENS ERIK
IPC: F16H1/22
Filed: 1980-05-17
Abstract: The drive for the rotor (10) of a compressor uses a set of helically toothed gearwheels so that little axial force is transmitted between the shafts, and axial bearings are not required. The rotor is mounted on a spindle (20) carrying a pinion (14) and this is in line with a driving gearwheel (12) mounted on a coupling half (18). The drive is transmitted through pairs of gears (22,24) mounted on lay shafts (26) equally spaced around the axis of the drive shaft. The helix angle of the teeth around the wheels (24) at one end of the lay shafts match those of the pinion and is selected to reduce the axial forces. Similarly the teeth of the pinions (22) at the other ends of the lay shafts have similarly selected helix angles.

Patent DE-3028442-A1 (DE)
Title: Control circuit for EM relay - uses solid state switching to apply HV to coil and give rapid response
IPC: H01F7/18
Filed: 1980-07-26
Abstract: The control circuit achieves rapid relay action by applying a high voltage across the operating coil. The relay coil is connected to a d.c. voltage source which would normally give a steady state coil current of several times the rated coil current. A solid state switching element is connected in series either side of the coil. To make the relay pick up, both elements are turned on. The current rises rapidly and the relay operates. When the current has risen to a limiting value as measured by a shunt the controllable element, normally a transistor, is turned off. The current then freewheels via a diode and slowly decays. At a lower current threshold the transistor is turned on again and the cycle repeats. The circuit thus gives rapid response without wasteful losses in a limiting resistor.
