Title: Method of mfr. of metal containers - has flat sheets welded together for feeding into circle of rollers to form cylinder
Inventor: GARCIA GARCIA SALVADOR
IPC: B21D51/18
Filed: 1976-10-29
Abstract: Round containers are manufactured in the machine from flat sheets, so that the necessity of transporting curved section from another machine is avoided. The flat sheets are lowered one by one from a pack and the edges are welded together. The length of material which is so formed is fed into a guide arrangement. The guide consists of rollers which are arranged in a circle. The strip of sheets which are welded together are formed into a cylinder after which the butting ends are also welded together.

Inventor: KRETZ ALBIN
IPC: H01R13/453
Filed: 1977-06-24
Abstract: The electrical plug device having a plug and coupling part is used to create an electrical protection against touching in that the current-carrying parts of the coupling part are covered when the plug is removed. When the plug pins (3) are inserted, a slide (9) is moved transversely with respect to the plug insertion direction, as a result of which the current-carrying sockets behind the slide (9) are then exposed. In the case of a first embodiment, the slide (9) is moved in that said slide (9) contains retaining holes (10) for the plug pins (3) and the slide, together with the plug pins (3), is pressed against spring pressure into a position (direction B) which is aligned with the current-carrying sockets. In the case of a second embodiment, the slide (9) has oblique surfaces against which the plug pins come to rest during insertion, the sockets being released by the plug insertion pressure. <IMAGE>

Title: Solenoid operated stop valve - has plug combined with mechanical valve closing for pipe breakage protection
Inventor: DETTMANN HEINRICH DIPL ING
IPC: F16K31/06
Filed: 1977-06-30
Abstract: The solenoid-operated safety stop valve is controlled by electrical switches or emitters detecting critical operating conditions. It is for use in conjunction with piping systems having mechanical protection against breakage. A mechanical valve closes automatically on pressure drop due to breakage and forms the breakage protection. It is combined with the closing plug of the solenoid valve. The single plug (3) can, when the flow pressure difference exceeds a predetermined limit, move in opposition to a return spring (28) in a guiding bell-housing (20), which itself is solenoid-operated. When the housing is in the central position, the plug is held between the return spring and one (27) opposing it in a central position allowing flow to take place. It moves into the closed position in opposition to the return spring.

Title: Irradiated nuclear fuel storage pond with variable water level - has sprinklers to wash down pond walls when water level falls
Inventor: SCHNEIDER WILFRIED
IPC: G21C19/07
Filed: 1977-07-11
Abstract: Pool or tank for storage or transporting of nuclear fuel elements contains water to a depth which may be varied during operation. A sprinkler appts. is used for washing down the wall of the pool with a liq. cleaning agent. Pref. the sprinkler is movable. More specifically, the sprinkler comprises a vertically adjustable pipe fitting to the wall of teh tank and equipped with nozzles, oriented towards the wall; the pipe may be mounted on a float so that it rises and falls with the water level. Used for the transporting or storage of nuclear elements in a nuclear power plant or fuel reprocessing plant. The water level may be raised or lowered during the handling operations, for example the handling container is placed in a dry pool which is then flooded for the handling operations, then again emptied before the container is removed. The sprinkler system enables the walls above water level to be cleaned, thus reducing or eliminating the source of radiation resulting from contamination left behind by the water.

Title: Speed servo-control for car - uses monitor to detect release of accelerator pedal and enhance motor damping
Inventor: COLLONIA HARALD
IPC: F02D41/02
Filed: 1977-12-02
Abstract: The servo speed control for the vehicle uses a simple servo motor to drive the throttle setting in response to the throttle control. A clutch is fitted between the servo drive and the carburettor to disengage the servo drive just prior to engaging the brakes or the main clutch. The servo clutch enables the throttle setting to return to idling before the clutch or brakes are applied and thus prevent the engine racing or stalling.

Title: PBX circumventing blocking by sticking bistable switches - sends signals to subscriber lines recognised as free to set bistable switches to rest state
Inventor: KRATZER PETER
IPC: H04Q3/545
Filed: 1978-03-10
Abstract: Continuous blocking of subscriber circuits by sticking bistable switches is prevented by provision of a subscriber circuit monitoring unit which recognises the subscriber circuit free or engaged state by interrogation of stores in connecting circuits. Bistable switches switch through the connecting circuits receiving the dialling signals. All subscriber circuits recognised by the monitoring device as "free" receive at short intervals signals which set the bistable switches in the subscriber circuits in a certain rest state.

Title: X=ray film cassette - has spring released from recess by film contact to move to window to show loaded condition
Inventor: MUELLER JUERGEN ING GRAD
IPC: G03B42/04
Filed: 1978-03-23
Abstract: X-ray film cassette has two light-tight chambers and a spring indicator to show whether or not the cassette is loaded with film. When the cassette is loaded, the film displaces a spring from a recess and causes the spring to move an indicator so that it does not show through a window. When the cassette is unloaded, the indicator shows because the spring returns into the recess.
