Title: Delayed action seat belt release - uses cutting blade driven in delayed action by spring against belt loop
Inventor: PLENGE GEORG DR PHIL
IPC: B60R22/32
Filed: 1977-09-08
Abstract: The mechanism serves to automatically release the vehicle user from the seat belt after an accident. The mechanism is applied on three point anchorage seat belts on one of the anchor points where the belt forms a loop. The device consists of a cylindrical housing in which a plunger-like element (6) is fitted slidingly against the force of a spring (4). The plunger is fitted with channels to take up the loop of the belt (1). The plunger also contains blade (3) and threaded plug (7). After an accident the sudden pull of the belt has slid forward the plunger (6) against the spring (4). After some delay the spring begins to act on the threaded plug (7) and drives it with increasing velocity against the rear end of blade (3) which then is propelled against the loop of belt (1) and cuts it through.

Title: Injector barrel for pressure die casting machines - with electrohydraulic control of plunger driving molten metal from barrel into die
Inventor: BLANKENHORN GERHARD DIPL ING
IPC: B22D17/32
Filed: 1977-11-19
Abstract: The molten metaal is poured into the barrel, and then a plunger drives the metal into the die. The plunger is driven hydraulically, and the pressure and/or the vol. of the hydraulic fluid is controlled by a rod(a) travelling together with the plunger. The periphery of rod(a) is provided with a row of marks(b) which are scanned by a stationary pulse generator feeding a pulse counter. When a prescribed number of pulses has been counted, a conventional electric circuit is used to adjust the pressure or vol. of the hydraulic fluid. The rod(a) may consist of a row of metal rings sepd. by insulation rings and assembled to form a tube sliding on a bar; the number of metal rings is counted via induction or capacitance as they travel past the pulse generator. The robust device withstands the severe operating conditions involved in die casting, but provides accurate control of plunger speed.

Title: Fibre material prodn. - using suction bed for carded sliver while being combed by upper brush
Inventor: NORDGREN GUNNAR DIPL ING
IPC: D01G15/00
Filed: 1977-12-08
Abstract: In the prodn. of fibres materials, a carded sliver is loosened and overlaid to cross the fibres for bonding and finishing. The carded sliver is allowed to run for a short stretch over a suction bed. At the same time, a brush unit combs the surface byu rotating in the same direction as, but at a higher speed than the movement of the card sliver. The brush unit loosens the rear ends of any fibre held by the suction so that they cross when they fall back to the material. The process optimises the carding, loosening and overlaying phases to give a consistent prod.

Title: Variable speed async. machine supplied via inverter - operates with separate control set points for magnetising and load currents
Inventor: KLAUTSCHEK HERWIG DIPL ING
IPC: H02P21/22
Filed: 1978-04-28
Abstract: The application of the modified variable frequency controller is principally to machines operating in all four quadrants. In order to ensure that there is always adequate commutation on the inverter section a reduction in output from one torque/speed point to another is effected by two controls. The load current set point is not reduced below a predetermined critical value necessary to ensure safe commutation. Any necessary further reduction is achieved by altering the magnetising current set point. A controller for this purpose can be added to the conventional variable frequency equipment.
Patent DE-2819051-A1 (DE)
Title: Wind power drive for water lift pump - which lifts float, whilst subsequent lowering moves piston producing water jet driving second piston
Inventor: DIESEND THEODOR DIPL ING
IPC: F03G3/00
Filed: 1978-04-29
Abstract: The unit converts wind power into usable energy. The wind power is used to drive pumps (Pu-Wi) to move water from a lower vessel (Wu) into a higher vessel (Wo). This water is subsequently allowed to flow into an adjacent vessel (Sch-H) by opening a valve (V3), resulting in a buoyancy member (S) being lifted off its support (St). The member is attached (T) to a piston (K) in a cylinder (Z). As the piston rises, the cylinder fills with water from a vessel (Wa) via valve (V1). Opening of valve (V4) allows the member (S) to sink. Closing (V1) and opening (V3) produces a water jet (Du) driving a turbine (Tu) as the piston comes down.

Title: Drive circuit interface between microprocessor and printer - has two groups of power transistors supplied from separate current sources to reduce number of logic elements
Inventor: KOEHLER THOMAS
IPC: B41J9/44
Filed: 1978-11-02
Abstract: The circuit drives several electromechanical transducers and can be used. e.g. as an interface between a microprocessor and a mechanical, magnetically operated printer. The number of logic elements and non-intergratable components employed is reduced by applying the data signals that select the electromechanical transducers directly to the bases of their associated power transistors. The transducers are in the power transistors' collector circuits. The power transistors' collectors are connected in two groups to two separate supplies. The emitters of the two groups of transistors are connected via the collector-emitter paths of two clocked switching transistors to a control current source.

Title: Security pressure-sensitive copying paper - heat treated to render surface non-gripping after transfer
Inventor: PROKSCH ALFRED ING GRAD
IPC: B41M5/10
Filed: 1978-12-01
Abstract: A security carbon paper is described in which the colour layer is converted by a grip layer for adhering the pressed sections to the copy sheet as for normal copies. A thermal treatment fuses the colour with the grip layer and renders it fixed so that subsequent pressure does not transfer any writing. Alternately the copy sheet can be covered with a grip layer to allow normal transfer from carbon paper. Heat treatment fuses the grip layer into the transferred writing and into the copy paper to inhibit any further transfer.
