A delay device consists of a piston-cylinder dashpot of the kind in which the piston displaces fluid from the cylinder to an external reservoir, but employs a putty-like composition as the 'fluid'-e.g. a silicone elastomer. The mechanism whose operation is to be delayed is connected directly or indirectly to the piston 8 and when a blocking element 22 is removed from a notch 21 in the piston the latter is forced into the cylinder by a spring 12, the mechanism being operated, e.g. when a second notch in the pistonrod reaches the level of the element 22. The piston moves slowly against the resistance of the putty-like composition 7 in the cylinder 20, the composition partly flowing into the annular reservoir 17 whose core 14 defines a throttling gap 16 at the end of the cylinder. To reset the device after use the base 18 of the reservoir is raised to push the kneadable composition back from the reservoir to the cylinder. For this purpose the base 2 of the device is rotatable with respect to the main device body 1, and rotating the base 2 rotates the reservoir base which has a screw-threaded engagement 19 with the body 1. The reservoir core 14 is movable axially to adjust the delay, being screw-threaded in the base 2 for this purpose.

Abstract: 1,258,619. Electrolytic production of adiponitrile. BADISCHE ANILIN & SODA-FABRIK A.G. March 14, 1969 [March 16, 1968; Oct.24, 1968], No.13524/69. Heading C7B. Adiponitrile is produced by electro-chemical hydrodimerization of acrylonitrile in a reaction mixture comprising acrylonitrile, a quaternary ammonium salt, water and if desired an organic solvent for acrylonitrile, at 10-60C. and pH = 1-10; the reaction mixture being passed through a narrow gap between solid electrodes 0À05-2mm. apart, or through the gap obtained between a solid electrode immersed in, but not wetted by, a liquid electrode. The quaternary ammonium salt may a tetramethyl- or tetraethylammonium salt of a mono-alkyl sulphate, sulphate, fluoride, tetrafluoroborate, fluorosulphonate, toluene sulphonate or benzene sulphonate. The organic solvent used may be a lower aliphatic alcohol such as isopropanol, methanol or ethanol; acetonitrile; ethers which are mixible with water, such as tetrahydrofurane, dioxane and glycol monomethyl ether; an amide which may include an alkyl or dialkyl radical, e.g. formamide, diethylacetamide; N- methyl-pyrrolidone; or the end product adiponitrile. A lower aldehyde may also be present and carbon dioxide or boron trifluoride may be added during electrolysis. Various electrodes which may be used include lead; copper; silver; amalgamated lead, copper or silver magnetite; graphite; gold; platinized titanium; platinum foil adhered to graphite; graphite, nickel or titanium coated with lead dioxide; tungsten-nickel alloys or magnetite. As liquid cathode, mercury or galluim above 30C. may be used. Solid electrodes used with a liquid cathode may be of various shapes. Fig.3 illustrates apparatus for carrying out the invention using liquid cathodes. The bottom of the cell body 1 contains circular depressions 4 partly filled with the liquid cathode material. Cylindrical anodes 2, having the edges of their lower faces rounded, are immersed in the liquid cathodes. The reaction mixture is pumped by pump 11 through heatexchanger 12 and enters the cell through nozzle 9 centrally of the anodes so that a thin moving film of electrolyte is maintained between the anodes and their corresponding cathodes. Electrolyte then overflows at 10 and is recirculated.

Abstract: 1,266,218. Gas/liquid contact apparatus. RHONE POULENC S.A. 25 Nov., 1969 [26 Nov., 1968], No. 57720/69. Headings B1F and B1R. In a reactor for co-current or countercurrent contact reactions between gases and liquids or between liquids in the presence of a gas or vapour phase, the tubes 5 in each stage extend above the upper horizontal supporting plate by a height of between 0.5 and 10 times the internal diameter of the tube 5. The tubes 5 are for upward liquid flow in each stage and are positioned coaxially with the gas inlet pipes 6.
