Title: Current reducing circuit for battery operated relay - has transistor in parallel with relay contact and transistor in series with relay
Inventor: ROSSBACH HORST ING GRAD
IPC: H01H47/04
Filed: 1979-02-22
Abstract: The current reducing circuit for a relay (A) operated by a battery (UB) permits a reduction of the holding current to keep losses to a min. A transistor (T1) is in series with the relay and the switch (a) controlled by the relay. A second transistor (T2) is connected across the switch. The first transistor is connected to a power supply by two resistors (R1, R2). At their junction is a connection to the second transistor, and also a diode (D) connected to negative. Thus the relay coil is in the collector/emitter path of the first transistor. The base voltage of this transistor is the control voltage of the second transistor. Alternative circuits use only transistors and resistances.

Title: Magnetically levitated and stabilised traction system - uses sec. conducting elements of vehicle of high conductivity to reduce prim. circuit power input
Inventor: HOCHHAEUSLER PAUL DR ING
IPC: H01F7/20
Filed: 1979-05-07
Abstract: The levitation system consists of pairs of three limb choke coils with the cores vertically side-by-side and connected such that the centre limb carries the sum of the flux in the two equal outer limbs. The secondary winding, forming part of the vehicle to be propelled and stabilised, covers, at least in part, all of the six magnetic poles thus created. Instead of aluminium the use of a higher conductivity material for the secondary winding on the vehicles is proposed, and the use of copper of copper alloys suggested. With copper the levitation height is practically doubled for the same primary circuit field strength. Thus for no increase in levitation the primary circuit input can be significantly reduced.

Title: Cable harness sealing system - has sealing inserts of heat activated material with shape recovery
Inventor: KUNZE DIETER DIPL ING
IPC: H02G15/113
Filed: 1979-12-06
Abstract: The sealing arrangement is provided for separation gaps in divided cable harness structures. It uses sealino inserts of heat activatable material, which has shape recovery properties, i.e. a so called shape memory. Preferably the material is heat shrinkable, e.g. a crosslinked thermoplastic material. If a heat adhesive layer is used, it may be provided on a forcibly deformed elastomer. The 'shape memory' of the sealing inserts is typically such as to provide after heat treatment a deformation, resulting in clearance-free clamping of the closing elements and the gaps to be sealed. The sealing insert may be of circular profile, whose diameter increases after heat treatment, or it may be of strip shape, or of triangular section. The strip-shaped insert may be folded. Various other shapes may be used, such as a complex shank configuration, or tubing of various sections.

Title: Automatic stop release for cassette recorder - operates release mechanism by solenoid energised when radio is switched on
Inventor: ITO SATOSHI
IPC: G11B31/00
Filed: 1979-12-19
Abstract: The automatic stop-release is suitable for in-car installations incorporating an F.M. tuner and amplifier. When switching on the radio it is desirable that the head and pinchroller are released as the recorder is switched off. This is achieved by a solenoid which is energised when the F.M. tuner or amplifier are switched on. This clears a catch (29) thus releasing a stop plate. This has the effect of releasing the play key lever (26) and consequently the freeing of a spring-loaded arm (38) which moves the head (47) and pinch roller (45) clear off the tape. It also frees a bar (31) and so opens the power switch (34) of the cassette recorder. The energising current for the solenoid is supplied by the discharge of a capacitor and is therefore of limited duration, allowing the solenoid to reset after its release operation.

Title: Shell accuracy testing system for quality control - uses camera focussed on target recording proximity ignition of fired shells
Inventor: BAUMER HANS
IPC: F41J5/12
Filed: 1980-01-24
Abstract: The target hit count verification system measures the amount by which a number of test shells selected from a mfg. batch fail to hit the target. The shells are aimed at a freely suspended target onto which a camera is focussed providing an image of the target and its immediate proximity. Each shell has a proximity fuse the camera registering the ignition of each shell as it passes the target. Pref. a video camera coupled to an image storage device is used. The camera is either triggered by the shell being fired, or it is triggered at a given interval after firing, e.g. using a microphone to provide the firing signal. The path of the shell may also be tracked by a radar device. A second camera may be focussed onto an electronic time recorder the two images from both cameras being combined.

Title: Baking oven - with convergent-divergent slots in top of centre partition in each deck
Inventor: SCHWENK LUDWIG
IPC: A21B1/24
Filed: 1980-03-14
Abstract: A baking oven has several decks of baking chambers. The baking chambers are subdivided by vertical partitions, parallel to the side walls with the alternate hot air supply and discharge ducts. A horizontal slot is left between the top of each partition and the ceiling for next higher deck. Guide plates on both sides of each slot are inclined downward and define a convergent-divergent cross-section for each slot. This makes is possible to increase production by wider decks, yet it prevents direct contact of the dough by the main hot air stream. The result is a uniform browning of the bread crust without excessive burn marks.

Patent DE-3016926-A1 (DE)
Inventor: PEER GUENTHER PH
IPC: B29C48/91
Filed: 1980-05-02
Abstract: An extruder has a nozzle from which it extrudes a strand formed of a mixture of wood chips and a synthetic-resin binder into a passage formed by a plurality of transversely and longitudinally movable walls. Opposite walls are urged transversely inwardly by respective hydraulic cylinders to compact and densify the strand as it cures, and other cylinders urge the walls upstream toward the nozzle with a force slightly smaller than the extrusion force. Thus as the extrusion force exceeds the opposite longitudinal biasing force the walls will move downstream with the strand, to return upstream between advance steps of the strand.

Title: Service lines for tilting process filter - pass through static component of rotatable support bearing to prevent entanglement
IPC: B01D29/075
Filed: 1980-06-18
Abstract: Appts. for the mixing, filtering, washing, drying etc. of prods. in a heated-wall rotationally symmetrical container which tilts about fixed bearings in a frame has a filter base below which filtrate is extracted, the base being surmounted by a rotatable and axially adjustable stirrer mounted in an internal neck formed from the container wall. On at least one side the container is connected to the frame by a roller support bearing. The lines which feed the product, filtrate, wall heating fluid, electric cable and other associated supplies to and from the container all pass through holes in an inner plate in the roller bearing which rotates with the container, which can then be tilted with very little relative change of position in these lines. The service lines are not entangled with each other by rotation, mating for greater safety. Seals can be of simpler static type instead of dynamic and the operating life of the lines is lengthened.
