Title: Safe for money and valuables with lockable drawers - has clockwork shaft acting with second locking mechanism, coupled to common drive shaft with single release position
Inventor: HIRSCHSON RICHARD
IPC: G07D11/00
Filed: 1978-12-30
Abstract: The release of the safe drawer or door can be actuated only after manual winding of a clockwork mechanism cooperating with the safe bolt lock. The clockwork operation depends on the position of its drive shaft in the locking or unlocking position. A second locking mechanism, cooperating with the first, having a recessed disc, is connected to the clockwork shaft via a common drive shaft. The clockwork shaft attains a single position during the entire drive shaft revolution for locking in both directions in relation to the locking surface of the bolt. This single locking position is attained when the common drive shaft has reached its rest position after reverse rotation. In this rest position, which also forms the rest position of both locking mechanisms, shift of the bolt to the opening position is impossible. The second locking mechanism is preferably in the form of a cam disc, the cam lobe length being at least identical to the length of the bolt shift path in its opening position.

Title: Ship's ice breaking attachment - has extendable air tube in bow below water line to inject compressed air below ice
Inventor: PFAHL HUBERT
IPC: B63B35/08
Filed: 1979-03-02
Abstract: The arrangement is intended for breaking ice in front of a vessel. It comprises an extendable air tube arranged in the bow below the water line through which compressed air can be forced below the ice so that it breaks through the buoyancy action of the air. The forward head of the tube may be mushroom-shaped with rearward pointing air outlets to drive the tube forward by jet reaction, and a winch may be provided to retract the tube or limit its extension. The ice is broken up by the action of the escaping air.

Patent DE-2935507-A1 (DE)
Title: Weft-break rectification in rapier loom - with self-acting pick finder initiated automatically on break detection
Inventor: MAASSEN HEINZ
IPC: D03D51/34
Filed: 1979-09-03
Abstract: In a semi-automatic procedure for repairing weft-breaks in a high-spead loom with rapier weft-insertion, a weft-break signal first effects disconnection of the main drive. A slow-running motor keeps the loom turning over, if necessary, until the rapiers are fully withdrawn from the shed, whilst the shedding mechanism is being reversed by a separate motor back to the pick on which the break was detected. An alarm signal alerts the operative to the stopped loom, and the broken pick is removed manually, the weft yarn is replaced or repaired, and the loom manually restarted. The procedure greatly simplifies and speeds up the repair operation, by automating the complex operation of finding the faulty pick which otherwise requires a long and careful series of manual operations.
Patent DE-2943324-A1 (DE)
Title: Polyphase converter system - uses currents or voltages made up to given duration at load by superimposition
Inventor: KRATZMAIR ERNST DIPL ING
IPC: H02M5/257
Filed: 1979-10-26
Abstract: The converter system has the currents or voltages of the separate phases having less than 180 degrees phase superimposed to give a duration of 180 degrees at the load. The currents or voltages being superimposed are generated at the primary side (1-3) of a transformer (4) and superimposed by the secondary circuit (7-9). The secondary windings are in delta configuration. Alternatively the subcurrents or subvoltages being superimposed are generated separately but using controllers sharing the same control. A transformer can be used that has two oppositely-phased winding groups on its secondary side.

Title: Extruder head backflow valve - has ring sliding on shaft with tapered gap at front position for polymer lubrication
Inventor: SCHIRMER Karl
IPC: B29C45/52
Filed: 1979-11-20
Abstract: A backflow valve in the nozzle head of an extruder has a pressure ring moving axially between stops and fitting inside the barrel with a gap for polymer flow; when the ring meets the rear stop face it closes this gap. The back faces of radial arms round the screw form the front stop and they are set (at least partly) at an acute angle to the front face of the ring in the direction of rotation of the screw to form a wedge-shaped lubricating channel. Design minimises wear from movement between the ring and front stop face.

Title: Explosive charge contains powder and granulate - of similar or different composition and combustion rate
Inventor: OVERSOHL WILHELM DIPL CHEM DR
IPC: C06B23/00
Filed: 1980-03-04
Abstract: A single-base or multi-base, extrudable explosive powder for tubular weapons contains granulate in the powder material posses possessing the same or a different speed of combustion. The powder and the granular material may have comparable or different compositions. The granulate may be made by cutting up solid strands of the material. The proportion of granulate to dry powder may be up to 80%. The grain size of the granulate is pref. 1/6-1/2 of the size of the extruded or pressed powder grains. The powder may be extruded in the form of solid or perforated cylinders. The powder may be surface-treated with centralite, phthalates or camphor. Whereas in the parent patent granulate having a different combustion rate from the powder was used, it is now found that certain types of powder may have a combustion rate which is independent of the temp. or is slower at higher temps. By combining powder and granules, a more efficient charge can be obtd. as the max. pressure which can be withstood is increased.

The holder (10) has a slot (13) through which the lever extends. This slot restricts the pivotal movement of the lever to one plane. This mechanism correctly positions a rear view mirror installed on the front door of a mirror vehicle.

Title: EM switch appliance with front and rear connection level - has coil former with two projections for receiving terminals, enabling four coil connections
Inventor: SIEDENBURG BERND DIPL ING
IPC: H01H11/00
Filed: 1980-05-08
Abstract: The connecting screws (36,37) of the switch terminals lie in the connection level next to the rear connection level. When the switch is converted, only the terminals need to be replaced, and not the coil former. The coil connection can be located in the rear connecting level, the front connecting level or in both of these. This design permits unobstructed access for the user and allows such a switch to be made with up to four coil connections. The switch, e.g. a contactor, is easy to convert because the projections (29,30) and shoulders (27) have recesses for receiving plug-in terminals which fit into chambers and serve for fastening the ends of the winding.
