Patent GB-2012316-A (GB)
Title: Electromagnetically controlled yarn guide
IPC: D04B15/58
Filed: 1978-12-27
Abstract: An electromagnetically actuated thread guide intended for use particularly in circular knitting machines, consists of an arm disposed between a pair of electromagnets, the arm being subjected to the action of at least one spring member acting against the attractive force of one of said electromagnets which is energised. Advantageously, the spring member constitutes at least a portion of said arm and causes an accelerated jump-off of the thread guide away from the deenergized electromagnet. <IMAGE>
Patent GB-785348-A (GB)
IPC: C01B6/00
Abstract: 785,348. Aluminium hydride; metal aluminium hydrides. FARBENFABRIKEN BAYER AKT.-GES. July 12, 1955 [July 12, 1954], No. 20141/55. Class 1 (2). Metal aluminium hydrides or aluminium hydride are prepared by reacting an aluminium halide with a finely divided mixture of a metal hydride with a metal which does not react with hydrogen to form a stable hydride. The finely divided mixture may be prepared, as in Specification 777,096, by the action of hydrogen on an alloy of a hydride-forming metal and a metal which does not react with hydrogen to form a stable hydride, the alloy being in a finely divided form and substantially free from other elements. Hydrides may be CaH 2  or MgH 2  and metals, which are unaffected during the reaction, may be copper and aluminium. In the example a suspension of magnesium hydride and aluminium in ether is boiled under reflux with aluminium chloride to form AlH 3  or Mg(AlH 4 ) 2  in ether solution, which is filtered off. The magnesium chloride and aluminium powder may be separated by melting or dissolving.
