Title: Carboxylic acid prodncid prodn by electrochemical oxidation of alcohol - with re-oxidation of dichromate used as intermediary
Inventor: WENDT HARTMUT
IPC: C25B3/23
Filed: 1974-04-30
Abstract: Discontinuous or continuous electrochemical oxidation o opt. substd. prim. alcohols to carboxylic acid using a dichromate as an oxidation intermediary with its subsequent re-oxidation is improved in that the re-oxidation of Cr(III) is preceded by extraction of organic matter from the Cr-contg. effluents using satd. or unsatd. hydrocarbons, which are then stripped, whilst the effluent is subjected to a thermal after treatment with addition of a re-oxidised chromate soln. at a temp. above 80 degrees C. The removal of the organic matter from the effluents prevents the lowering of the oxygen overpotential, which otherwise would prevent the re-oxidation of Cr3+ to Cr2O72- as oxygen would be predominantly formed on the anode.

Title: Vehicle servo assisted hydraulic steering - has reaction cylinder to limit small movement response and fix large movement response
Inventor: JABLONSKY ERICH
IPC: B62D5/24
Filed: 1974-09-02
Abstract: A fork on the steering column operates hydraulic control valves, moving them in opposite direction. This puts one side of the steering operating cylinder into connection the high pressure side of a pump, while putting the other side into connection with the low pressure side. Connection of the higher pressure also to a reaction chamber at one end of the control valve provides resistance to the movement which gives 'feel' to the steering, it is held at a limiting value when a needle valve overcomes a spring and cuts the reaction chamber off from the high pressure source, and may also connect it to the low pressure sink. Steering continues against this constant resistance.
