Abstract: 1,126,939. Boots &c. DESMA-WERKE G.m.b.H. 25 July, 1966 [2 Sept., 1965], No. 33305/66. Heading A3B. A method of moulding a lightweight sole of rubber or synthetic plastics material directly on to a lasted upper is carried out in two stages at different pressures, the first stage being effected under a sufficiently high pressure to maintain the material in the mould in a compact state, the pressure then being relieved so that pores are formed in the material during the second stage. The material may be injected into the mould under pressure using an injection moulding machine, the high pressure being produced during the first stage by a piston or the injection moulding machine. Alternatively the material may be introduced into the mould under normal pressure is thereafter subjected to the high pressure by reduction of the mould cavity e:g. by shifting the bottom plunger or the last. Preferably the material introduced into the mould does not completely fill out the mould cavity. Suitable materials for the sole are natural or synthetic rubber, polyvinyl chloride, polyurethans, polyethylene, polystyrene or acetyl cellulose.

Title: Improvements in or relating to a process for treating mercaptans
Filed: 1948-12-30
Abstract: A disulphide R.S.S.R, where R is alkyl, aryl, aralkyl or cycloaliphatic, is prepared from a mercaptan R.SH by oxidation with a solution containing cupric ions and bromide and/or chloride ions in a monoalkyl glycol or polyglycol ether together with from 3 to 20 per cent weight of water at a reaction temperature not exceeding 175 DEG F.  The group R preferably contains no more than 8 carbon atoms.  The method of recovering the product depends on what glycol ether is used as solvent, e.g. with the monomethyl ether of ethylene glycol or diethylene glycol, the reaction mixture forms two phases, one containing the disulphide and the other being the spent oxidation solution which is regenerated by oxidation with an oxygen-containing gas and removal of the resultant water; on the other hand with diethylene glycol monobutyl ether the reaction mixture is homogeneous.  An example is given of the preparation of di-tert.-butyl disulphide.

Filed: 1971-07-20
Abstract: 1361462 Automatic speed control ROBERT BOSCH GmbH 20 July 1971 [21 July 1970] 33865/71 Heading G3R [Also in Division F1] In a speed control circuit for an internal combustion engine, a feedback loop includes an operational amplifier that controls the engine fuel supply and which is fed with an engine speed signal and a desired supply signal, the amplifier output being fed with a pressure dependent signal. In the embodiment, the position of a fuel injection control magnet 22 i.e. the speed of a diesel engine 10, is controlled by amplifier 21 which receives the output of an operational amplifier 17, fed with a reference signal from accelerator pedal 16 and a measured engine speed signal, and also receives a signal from circuit 25 in dependence upon the ambient atmospheric pressure or the engine intake manifold pressure. The pressure is sensed by diaphragm 29 to vary the position of core 28 in coil 27, that is fed by oscillator 26 and whose tapping, via diode 30 and smoothing circuit 32, 33 biases transistor 31, which thus supplies a pressure dependent signal. To increase stability, engine speed and magnet position signals are fed back to fuel pump 11 and amplifier 21. Under normal operation, the pressure dependent signal is over-ridden by the output of amplifier 17, which reverse biases diode 36, but near the smoke threshold the amplifier 17 is blocked and the fuel supply controlled only by the measured pressure.
