Patent DE-3841058-A1 (DE)
Title: Valve bag or tubular bag
Inventor: OTT GERNOT
IPC: B65D30/24
Filed: 1988-12-06
Abstract: In a valve bag or tubular bag having side folds, a valve produced by folding is arranged at one end in the corner, which valve is connected by bonding to a valve plate (21). For easier handling of the bag when filling using the valve, the valve opening is to be opened automatically if possible to the extent that the valve can be fitted onto a filling nozzle with one hand. For this purpose, one bonding region (24a) is arranged in the outer half of the valve plate (21) perpendicular and symmetrical to the fold edge (22) and two further bonding regions (24b) are arranged in the inner half of the valve plate (21) and with spacing from the fold edge (22) thereof. <IMAGE>

Title: Sealing air vent for end cover of mine - involves spring-loaded valve which closes as cover is extended
Inventor: MATHEY CHRISTOPH DIPL ING
IPC: F42B23/24
Filed: 1989-06-24
Abstract: The mine or similar munition has a flexible cover (4) fitted over the chamber (9) containing the explosive charge. During storage, the cover (4) is pressed inwards into the chamber. When the munition is prepared for use, the cover is pressed outwards by a spring (11) and air flows into the chamber through a valve (8). This valve (8) is held open by a pin (17) attached to one end of a cable (14) which has its other end attached to the body of the mine. As the cover (4) moves outwards, the cable (14) is subjected to tension which withdraws the pin (17) and allows an internal spring to close the valve (8) and seal the chamber (9). USE - Explosive mines.

Title: Electronic yarn clearing on a winder - by introducing thicker yarn during spinning whereby yarn is sensed by electronic clearer, at winder before being cut and drawn into suction units
Inventor: SCHREIBER MANFRED
IPC: D01H13/22
Filed: 1991-02-15
Abstract: Process is based on a thicker yarn being introduced during spinning to ensure continuity between broken ends. The reserve yarn is wound on the cop and spliced at the production side only. At the winder, the electronic cleaner senses the thicker yarn; cone winding is stopped, the thicker yarn retrieved, cut away and drawn into suction units consecutively at each stage. The loose end on the cop is also withdrawn. The electronic controller now proceeds as for broken ends, splices and proceeds with winding if successful. Otherwise, causes a cop change, to release a new end. The appts. is also claimed. The cop (12) is mounted on a carrier plate (10) and brought into position on the winder by the conveyor (16, 18). A suction tube (20) releases the loose end of yarn inserted into the cop tube, drawing it up the anti ballooner tube (22) across the presence detector (30) so that it can proceed through the tension plates (32), paraffin applicator, (36) splicer (40) and to the traverse winder and cone (34).
