Patent DE-2745458-A1 (DE)
Title: Decontaminating structures radioactively contaminated on one face - using explosive charges on opposite face to break away radioactive layer
Inventor: GROESSLER PETER DIPL ING
IPC: G21D1/00
Filed: 1977-10-08
Abstract: Objects which are highly radioactively contaminated on one side (the inner or outer face), esp. large structures such as those to be demolished when finally closing down a nuclear power plant, are decontaminated by applying explosive charges to the opposite face in sch a quantity and distribution that the highly radioactive layer is broken away in transportable fragments from the face of the wall. The explosive may be applied in the form of explosive panels, flexible explosive, or liquid explosive. The shattering action removes from the decontaminated face the material which must be broken down and transported away under shielded conditions. The remaining, larger quantity of the vessel does not then need to be broken down into such small fragments and does not require special protective measures in removing it since the contaminated parts have gone. As a result of the superposition of pressure waves and attenuating waves the contaminated side of the wall is broken down with relatively small charges.

Title: Automatic embroidery machine - has electric and/or electronic controls to allow mirror image patterns
Inventor: SCHALLERT HUBERT
IPC: D05C9/06
Filed: 1977-10-26
Abstract: For the automation of an embroidery machine, A punched card provides the data for the movment of the embroidery grid. There is an arrangement of electric and/or electronic switch and control units to reverse or partially reverse the directional commands from the punched card. The system allows mirror image patterns to be reproduced. The reader for the punched card, to register the selected movement direction, has one arm of a two-armed lever which pivots in actin, and control units such as control sinkers are provided for control. The other free arm of the lever is mounted with a switch according to the angle of movement. The control sinkers are operated by electro-magnets, such as a rotary magnet, regulated by the switching unit. The switches are in the form of proximity switches which make contact on proximity of the free arm of the lever and when it dwells in this position. The magnets are held by springs in the inactive mode. The switching unit has a counter system for the pattern rows which is preset for special functions in automatic embroidery such as stoppages, mirror image patterns and the like. The counter is controlled by a special control sinker to stop the embroidery machine in conjunction with a proximity switch. The special function control sinker has an extension ranging across its direction of movement with a switch unit in its path to bring the embroidery machine to a stop.

Title: Motor vehicles pressings mfr. from continuous strip - involves several pressing operations before transverse shearing
Inventor: ZIMNOL ALFRED
IPC: B21D35/00
Filed: 1977-11-12
Abstract: Metal pressings for the automobile industry are made from a continuous strip (1) which is fed from the coil (2). The strip (1) passes through a guiding device (3) and then through various stamping and piercing presses (7, 8) before being cut to the required length by the shearing press (6). The sheared and partly formed pressings are then placed in stacks (4) ready for the next operation such as deep drawing. By performing as many operations as possible whilst keeping the strip in one continuous piece the need for special transport devies between these operations is eliminated.

Title: Recovery of polystyrene foam shock-absorbing packing chips - using suction appts. for filling into plastics sacks and for maintaining compensating vacuum to prevent collapse
IPC: B65B69/00
Filed: 1978-07-05
Abstract: Device is described for recovering by suction particulate material such as plystyrene foam chips or shapes used as impact-absorbing packing for the despatch and/or storing of delicate merchandise. The material is sucked into air-tight, collapsible, receptacles, e.g. plastics sacks. Bag is placed into an evacuable container to which a suction head with suction hose is fitted so as to evacuate the space between its inner wall and the sack in such a way that the resulting reduced pressure that tends to collapse the sack is at least neutralised. As a result, the sack remains dimensionally stable and inflated.

Title: Lightweight load-bearing floor for vehicle - has corrugated reinforcing insert and light wood or plastics surface
Inventor: WACKENHUT ERNST
IPC: B62D33/02
Filed: 1978-10-16

Title: Overload protection semiconductor circuit - has AND=gate driven by signals due to drop across protective resistor and by delayed input
Inventor: KUHN MICHAEL
IPC: H02H3/087
Filed: 1979-04-23
Abstract: The protection resistor of a semiconductor circuit feeding a short-circuited load requires little power. The AND gate (4) provides the tripping signal when receiving a signal due to a voltage drop across the protective resistor (7) and a delayed switching signal from a terminal (I). The delay is determined by a resistance and capacitance combination (2, 3) connected to an input terminal (I). The control circuit includes an exclusive OR gate (10) connected to the AND gate (4) and to the source of the switching signals. The switching transistor emitter-collector circuit is connected to the load (6) (lamp) and to the protective resistor (7) while the base is connected to the terminal, (I).

Title: Short-circuited transmitting tube discharge switch - has lifting magnet operating switch rod attached to yoke of holding magnets
Inventor: GERLACH DIETER ING GRAD
IPC: H01H79/00
Filed: 1979-05-11
Abstract: The fast discharge switch for a short-circuited transmitting tube which is produced and operated with a low cost responds within 15 msec after the arrival of the tripping signal. The vacuum switch is operated by a rod controlled by a lift magnet against the resistance of a spring. The lever attached to the rod acts as a magnetic yoke which closes the holding magnet core when the discharge switch is in its open position. The limit switch in the circuit of the lifting magnet breaks the circuit when the discharge switch is open. Holding magnets are symmetrically located w.r.t. the actuating rod, while the lever exhibits a nonmagnetic sheet on the side facing the holding magnets.
