Title: Shotgun cartridge plastics case with smooth edge - is closed by holding ring with step and contact lip which retain end wad in case
Inventor: RAMMENSEE HORST DIPL PHYS DR
IPC: F42B7/12
Filed: 1976-10-29
Abstract: The shotgun reloadable cartridge has plastic case. The uncrimped plastics case is closed by hard brittle disc and holding ring. The closing components form a single unit and the ring holds the disc in closing position. The case end is smoothly closed without special profiles on case rim and without crimping. The closing unit does not expand case end and ensures adequate damping. The inner smooth part of cartridge case top rim (1a) supports holding ring (3) which has sealing lip edge (3a). The latter is pushed firmly against the case smooth rim by the internal pushing force of propellant gases. The holding ring has step by which it contacts cartridge case top edge for correct depth of insertion.

Title: Automatically controlled pivoting frame bandsaw - has saw supported near workpiece while support is automatically adjusted during sawing
Inventor: STOLZER PAUL
IPC: B23D55/08
Filed: 1977-01-07
Abstract: The bandsaw (6) runs over two discs (4, 5). The discs are mounted on a frame (3) which can be pivoted about a point (2) on the base (1) of the machine.

The refractive index of the polymerised material pref. corresponds with that of the material to be impregnated. The plastic material is pref. with a low colour value. The object may or may not be transparent. Contrasts may be made by filling voids with colour or by means of gas. Plastic materials are pref. acrylic, polyester, epoxide, polyurethane or silicone resins. The polymerisation is pref. effected on plates or sheets. Solns of plastic materials employ, ethanol, acetone, dichloromethane and air. Impregnation is pref. by perfusion, the object having a higher vapour tension than the plastic material soln. The medium is pref. evaporated and replaced by the plastic soln. The medium is pref. withdrawn as a gas by aspiration under vacuum. The impregnation is pref. carried out by perfusion, or with the acid of vacuum. The solvent is evaporated after hardening has been carried out.

Title: Water-level regulator for dishwasher - is completely emptied with each pump cycle via siphon and compensating chamber
Inventor: KAEFFERLEIN HEINZ
IPC: A47L15/42
Filed: 1977-07-01
Abstract: The dishwasher mechanism contains a suction siphon (29) which leads from the connection (23) to the level regulating vessel (15) to a compensating vessel (26) attached to the emptying pump (4) system. This ensures that all the water which has overflowed from the riser (22) into the chamber (2) of the level regulating vessel (15) which forms the air trap is completely drawn off with each emptying cycle. Once filled with water the compensating vessel (26) prevents the intake of the air cushion from the siphon through the emptying pump and ensures complete emptying of the chamber via the siphon which is released by the pump. The compensating vessel can form a communicating pipe leading to the tub and is connected to the emptying system by a nozzle, water spray pipe, Venturi pipe etc.

Title: Temp. measurement circuit using variable resistor - uses ration between supply voltage and sensor voltage drop to give temp. indication
Inventor: JAUCH WIELAND
IPC: G01K7/24
Filed: 1978-01-18
Abstract: The circuit uses a temp. sensitive sensor whose resistance change generates a corresponding voltage change which is measured and compared with a reference voltage. The measured voltage also indicates the sensor temp. A variable voltage source delivers several voltages. The first voltage generates the reference voltage, and the second supplies the sensor. The sensor is a part of a voltage divider to which the suply voltage is applied, and from which the measurement voltage is collected. The voltage source voltage serves as a reference voltage, and the ratio between the supply source voltage and the measurement voltage is used for temp. display.
