Title: Manufacture of dimers
IPC: C25B3/29
Filed: 1961-12-11
Abstract: 967,956. Forming dimers electrolytically. MONSANTO CO. Dec. 11, 1961 [Dec. 12, 1960 (2); Oct. 16, 1961 (2)], No. 44296/61. Heading C7B. Hydrodimers of aliphatic mono-olefinic nitrites, esters of carboxylic acids, or carboxamides are formed by electrolysis using a cathode of hydrogen over voltage greater than copper, e.g. -1À8 to 2À1 V. relative to a calomel electrode, the concentration of the olefinic compound being at least 10% by weight in an aqueous salt-containing electrolyte, and maintaining the pH value at greater than 7, preferably 8-9. A salt is present as a conductor, preferably an alkali metal sulphonate of a quaternary ammonium compound. A wide range of suitable conducting salts is given and includes mono- or polyalkylamine salts of sulphonic or alkyl sulphonic acids, and the corresponding alkylolamine compounds; sodium tetra alkyl ammonium sulphonates; alkali metal salts of aryl or aralkyl sulphonic acids. The pH value may be conveniently controlled by using a diaphragm cell, the rising pH value in the catholyte being reduced by adding acid, e.g. by leaking into it the acidic anolyte, or by adding an acid, e.g. acetic or phosphoric acid. The process is applied to convert compounds containing less than 20 C atoms, e.g. acrylonitrite to adiponitrite, maleonitrile to butane- 1,2,3,4-tetracarbonitrile, methyl acrylate to dimethyl adipate, propyl maleate to tetra propyl butane-1,2,3,4-tetracarboxylate, acrylamide to adipamide; aryl aliphatic derivatives are also exemplified. The hydrodimerization product is a "head-to-head" addition, coupling taking place at the beta-C atom to the functional group. The concentration of a salt in the electrolyte may be 30% by weight and of the alpha-beta mono-olefinic compound up to 50%, where required polar solvents may be added to increase the solvent power, e.g. acetonitrile, dioxane, lower alcohols, dimethyl formamide, or ethylene glycol. The cell used preferably has a porous diaphragm, e.g. an unglazed porcelain cup, the anode being, e.g., carbon, gold, nickel silicide, or lead alloys, or lead deposited on a copper screen. The cathode may be, e.g., mercury, gallium, cadmium, tin, or lead-mercury alloy. The dimer product is then separated by neutralizing, extraction with a solvent, and fractionation.

Abstract: 1,028,607. Controlling vehicles. CATERPILLAR TRACTOR CO. Nov. 2, 1964, No. 44541/64. Heading B7H. [Also in Division F1] In a heavy duty motor vehicle wherein slippage of the driven wheels may occur, the engine drives an hydraulic pump which is in circuit with a motor connected via a oneway clutch to the non-driven wheels and delivers fluid to an extent slightly greater than that acceptable by the motor so that a slight pressure is maintained on the motor input side, a branch line being taken from the motor input line to a throttle control device whereby, if the pressure in this line builds up due to the driven wheels slipping, the throttle control is actuated to reduce the engine speed. The system is also applied to a vehicle having two sets of driven wheels with a separate engine for each, each engine driving a pump, the pumps being connected in a circuit with a branch from the pressure side to a throttle actuator, so that, if one set of wheels rotates faster, due to wheel slip, the actuator reduces the engine speed. In a modification of the latter system, Fig. 4, a set of wheels 76 is driven by an engine 77 which also drives a pump 79 delivering to one side of a piston valve device 82 and a further set of wheels 72 is driven by an engine 73 which also drives a pump 79 supplying fluid to the other side of the piston valve device 82. A pressure fluid supply line 101, 97 from the engine 73 passes through the space between the pistons 93 and 94 to the engine sump a branch of line 97 leading to a device 98 in the throttle control system. If the wheels 72 slip, engine 73 rotates faster and the pressure generated by pump 79 causes piston 94 to block line 97 whereby pressure builds up to actuate the device 98 to reduce throttle speed. An electrically operable isolating valve 103 is provided.

Abstract: 1,202,043. Laminating machine. STOREY BROS. & CO. Ltd. 6 Oct., 1967 [11 Oct., 1966], No. 45469/66. Heading B5N. A machine for laminating a flexible sheet 22, e.g. of P.V.C. or other plastics materials or paper to a rigid sheet 14, e.g. of plaster board, hardboard or chipboard, comprises lateral guiding means, e.g. rolls 30 for the rigid sheet and a pair of nip rolls 18 and 20, one of which (as shown, roll 18) having a degree of freedom in a plane parallel to the plane of the rigid sheet as the latter passes between the rolls. This mounting of roll 18 is intended to prevent the tendency of the nip rolls to slew rigid sheets having appreciably varying thicknesses against the guide rolls 30, and thus prevent consequent damage to the edges of sheets 14. Roll 18 is mounted in two bearings 34 (only one shown), each of which is carried by an arm 24 pivoted at 26. Hydraulic rams 28 urge roll 18 towards roll 20. Bearings 34 are slidable longitudinally of the arms 24 and each is connected by a rod 38 to an hydraulic piston/cylinder unit 40. The cylinders of these two units are interconnected (by conduits 42, 44, Fig. 2, not shown) so that movement of one end of the roll 18 in a downstream direction results in upstream movement of the other end and vice versa. Alternatively, each cylinder may be closed on one side of the piston and contain a compressible fluid to provide for damping movement of roll 18. The arms 24 may be in the form of bell-cranks and the point of application of rams 28 may be at the roll's side of pivot 26.
