Title: Shuttle - with means for maintaining weft yarn - under uniform tension during withdrawal from bobbin
IPC: D03J5/06
Filed: 1971-04-29
Abstract: Shuttle, which contains a means for damping and restraining withdrawal of a weft yarn from a supply bobbin during the running of the shuttle, thereby maintaining the yarn drawn from the supply bobbin under uniform tension throughout the withdrawal, comprises a shuttle body having a guide wheel rotatably mounted on a pin journalled in the rear end portion thereof, a pair of thin braking plates applied on the opposite sides of the shuttle body, a non-magnetic supply bobbin rotatably mounted on a stepped pin fixed within a recess or cavity formed in the shuttle body, with the bottom face of the supply bobbin slidably contacting on the bottom of the cavity, an annular magnet piece fixedly mounted on the top portion of the pin described, and a ferromagnetic cap threaded on the top of the supply bobbin. During withdrawal of a weft yarn, the stationary magnetic piece interacts with the ferromagnetic cap of the rotating supply bobbin to provide a counter torque for precluding excessively rapid rotation of the bobbin.

Patent DE-2166763-A1 (DE)
Title: Catalyst on continuous heat-resistant substrate - applied by impregnating particulate carrier and depositing it by flame-spraying
Inventor: KOBERSTEIN EDGAR DR
IPC: B01J37/34
Filed: 1971-10-15
Abstract: Noble metal and non-noble metal oxide catalysts are deposited onto a continuing heat-resistant substrate by impregnating a particulate carrier, such as gamma-Al2O3 powder, with a catalyst precursor, and then depositing the impregnated and calcined catalyst carrier onto the substrate by flame-spraying. By this method, catalysts can be deposited on reactor walls or linings, baffles, etc.; this is in some cases more convenient than the use of catalyst carrier beds or other known methods. The adhesion of the catalyst carrier to the heat-resistant substrate is strong. Flame-spraying ensures that the porosity of the catalyst system and its specific surface area are sufficient for catalytic reactions. The method can be applied to treatment of exhaust gases from internal combustion engines.
