Abstract: 1,029,638. Cushions, &c. PRESSED STEEL CO., Ltd. Aug. 12, 1964 [Aug. 14, 1963], No. 32043/63. Heading A4M. [Also in Division B5] A method of moulding articles such as cushions, seats and armrests comprises forming an outer skin from synthetic plastics by a slush moulding or rotational casting process, partially curing or gelling the skin, introducing a foamable plastics mixture, which by a similar process is moulded to form a layer on the inner surface of the skin, curing or gelling to bond the layer to the skin, and finally introducing a foamable mixture which on foaming fills the remaining space within the skin, permeates the inner surface of the layer, and is bonded thereto on curing. In the embodiment described the skin is formed from a polyvinyl chloride plastisol, the layer from a foamable polyvinyl chloride plastisol mixture, e.g. 16 parts by weight of the synthetic resin with 0.5-10 parts by weight of water, and in any case such that the inner surface of the layer has a cratered appearance, and the filling from a resilient urethane foam forming material.

Title: Improved latching device for use with elongated articles of rod or tube form
Inventor: TINDALE JOHN
IPC: G05G5/06
Filed: 1959-09-25
Abstract: 958,791. Stud and socket fastenings. ELLIOTT BROS. (LONDON) Ltd. Sept. 21, 1960 [Sept. 25, 1959], No. 32781/59. Heading E2B. [Also in Division G6] A latching device in combination with a rod, particularly suitable for use with control rods in nuclear reactors, comprises relatively movable inner and outer tubular members, E and A when passing a rod P, and detent elements formed by balls H, J carried on the member E, the balls being projectible in consequence of relative movement between the members E and A into and out of positions wherein movement on the part of said rod is imparted or not imparted to the member E, a predetermined number of backward and forward movements of the rod being necessary before the member E unlatches the rod. In operation, the rod P is lifted by a winch and is able to pass the lower balls J which in Fig. 1 are situated in recesses C in the member A. The upper surface of the rod contacts the upper balls H which project from the member E and the member is raised until the balls H move into an annular recess M to allow the rod to be lifted clear of the member A if desired. When the rod P is removed, it pivots some triggers T such that the heads of the triggers engage in a slot 8 in the member A to support the member E. When the rod is lowered it moves the member E downwardly by contact with the balls J. As the member is raised or lowered it rotates due to detents on the member A co-operating with a groove F in the member E, a development of the member E in Fig. 8 showing this groove. The member rotates 30 degrees with each movement such that with each complete up and down movement the lower balls J alternately occupy the recesses C or project inwardly to prevent further lowering of the rod P. To lower the rod from this position shown in Fig. 3, therefore, the rod must be first raised and then lowered in order to rotate the sleeve the requisite amount.

Title: Improvements in or relating to the manufacture of vulcanised rubber
IPC: C08K5/00
Filed: 1929-11-01
Abstract: Aryl dithiocarbomates are prepared by the interaction of reactive halogen derivatives of benzene or its homologues with dithiocarbamates.  The term reactive halogen derivative of benzene includes halogenated benzenes or alkyl, aryl, or acyl, derivatives in which the presence of additional negative radicals, e.g. nitro groups, renders at least one of the halogen atoms reactive towards the alkyl substituted dithiocarbamates. The term dithiocarbamates includes aliphatic, aromatic, or heterocyclic derivatives whether employed in the free state or in the form of their salts.  In an example, di-piperidino-dithiocarbamate is hydrolyzed with aqueous caustic potash and an alcoholic solution of 4-chloro-1 : 3-dinitrobenzene is added and the mixture refluxed; a yellow crystalline product is finally obtained of the composition <FORM:0340083/IV/1> In other examples the above compound is obtained in one step by refluxing the initial products in alcohol or by grinding them together in a mortar.  The di-piperidino dithiocarbamate may be replaced by zinc diethyldithiocarbamate and by diethylammonium-diethyl-dithiocarbamate, and the 4-chloro-1 : 3-dinitrobenzene by picryl chloride.ALSO:Vulcanization accelerators are prepared by the interaction of reactive halogen derivatives of benzene or its homologues with dithiocarbamates.  The term reactive halogen derivatives of benzene includes halongenated benzene or alkyl aryl or acyl derivatives in which the presence of additional negative radicals e.g. nitro groups renders at least one of the halogen atoms reactive towards the alkyl substituted dithiocarbamates.  The term dithiocarbamates includes aliphatic, aromatic, or heterocyclic derivatives thereof whether employed in the free state or in the form of their salts.  Example:-2,46 grams of piperidene piperidene-1-carbothionolate is dissolved in water and 0,56 grams of caustic potash added.  The mixture is boiled until the odour of piperidine has disappeared, when 2 grams of 4-chloro-1 : 3 dinitro benzene in alcohol is added and the mixture refluxed for 15 minutes. This reddish solution is evaporated to dryness and the residue boiled with alcohol.  The potassium chloride which remains is filtered off, and the alcoholic solution is allowed to crystallize.  A red oil separates out which sets to a solid and yellow crystals separate from the mother liquor which have the composition:-  <FORM:0340083/V/1> Either of these products may be used as an accelerator.  In other examples the above compound is obtained in one step by refluxing the initial products in alcohol, or by grinding them together in a mortar.
