Patent DE-2455744-A1 (DE)
Title: Accumulator gases recombination plug - with gas permeable catalyst container around tube to atmosphere offering minimum flow resistance
Inventor: NANN EBERHARD DR PHIL
IPC: H01M10/52
Filed: 1974-11-25
Abstract: H2 and O2 released by accumulators are analytically recombined to water vapour which is condensed and returned to the battery in a plug with a chamber. The latter is joined at the bottom to the gas space of the battery and has an exit to atmosphere which is overlapped by a gas-permeable catalyst container. Exit and catalyst container offer a minimum of flow resistance, and the catalyst container is arranged concentrically to the tube representing the exit to atmosphere. This plug recombines the released gases with a high efficiency. It causes no pressure rise in the accumulator cell. The greater temperature gradient between the exothermic reaction of the water vapour produced by the catalyst and the cooler plug walls prevents air escape of water vapour to the atmosphere.

Title: Stencil belt with reinforced edges for silk screen printing - preventing tearing at edges and allowing control by edge sensors
Inventor: MITTER MATHIAS
IPC: B41F15/34
Filed: 1975-07-15
Abstract: The belt which is guided over rollers in the printing mechanism is reinforced at >=1 of its edges. This may be effected by folding a reinforcing strip of thermoplastic material around the edge and welding it to itself through the stencil. Alternatively where one flap of the folded strip overlaps the other, it is welded to itself from the side of the shorter flap, and welded into the material of the stencil from the side of the longer flap. Pref. the stencil is welded to a PVC or polyurethane film. Other ways of reinforcing the edges are by incorporating in the edges reinforced warp threads of heat-sealable material which are heat-sealed to the stencil material; or by dipping, spraying, brushing, etc. the edges with a latex material. The edge of the stencil may be shaped or cut precisely according to the printing pattern on the stencil, so that running of the belt can be monitored by edge sensors.
