Title: Process for the electrolytic deposition of gallium or gallium and vanadium from alkaline solutions arising in the production of alumina
Inventor: RUBINSHTEIN GEORGY MIKHAILOVIC
IPC: C25C1/22
Filed: 1979-05-29
Abstract: The process for the electrolytic deposition of gallium or gallium and vanadium from alkaline solutions arising in the production of alumina consists in the electrolysis being carried out employing solid electrodes at a cathode current density of 200-1000 A/m<2>, a voltage of 3.4-4.5 V, a temperature of 28-37 DEG C in the presence of a metal which was previously introduced into the starting solutions in a 1- to 10-fold excess based on gallium and which in the event of joint electrolytic reduction with gallium forms an alloy therewith which under conditions of the electrolysis does not passivate. The process for the electrolytic deposition of gallium or gallium and a vanadium concentrate from alkaline solutions can be used in the production of alumina.

Title: Removable anti-skid means for a vehicle wheel, in particular a motor-vehicle wheel
Inventor: NEHER KONRAD
IPC: B60C27/06
Filed: 1979-09-18
Abstract: Two parts (10, 20) formed in each case from a longer and a shorter strip (12, 22) and from transverse chains (13, 14, 23, 24) connecting the ends of the two strips engage around opposite segments of the vehicle wheel. Only the longer strips, lying on the outer side of the wheel, of the two parts (10, 20) are connected to each other. The shorter strips (12, 22), lying on the inner side of the tyre (5), are only held by the transverse chains (13, 14, 23, 24). The most heavily worn part of each transverse chain (13, 14, 23, 24), namely that adjoining each shorter strip (12, 22), is formed by two chain sections (35, 36). Said sections are dimensioned such that one (35) of the two sections (35, 36) secures the strips (12, 22) on the vehicle wheel if the other section (36) breaks, and such that then at least one part of the broken section (36) strikes against the wheel arch of the vehicle and thus warns the driver. This prevents the anti-skid means from being hurled away from the vehicle in the event of a chain breaking, which would be dangerous. <IMAGE>
