Abstract: 1,195,749. Sulphur-containing cycloaliphatic derivatives. LUBRIZOL CORP. 13 Oct., 1967 [19 Dec., 1966; 1 Aug., 1967], No. 46823/67. Heading C2C. [Also in Division C5] Oil-soluble sulphur-containing cycloaliphatic compounds are prepared by heating sulphur and at least one unsaturated cycloaliphatic compound of formula in a molar ratio of sulphur tocycloaliphatic compound of from 0.5 : 1 to 10 : 1, where in the above formula n and n<SP>1</SP> are each integers of 0-9 with the proviso that 5 # n + n<SP>1</SP># 10 and at least one pair of Rs (one R from each of two adjacent nuclear carbon atoms) together form an additional carbon-carbon linkage so that there is at least one unsaturated linkage in the cycloaliphatic nucleus; and the remaining groups R are hydrogen; a hydrocarbon group; a heterocyclic radical; the radical in which n is 0 or 1 and m<SP>1</SP> is 0 or a whole number up to 20, and the Ws are oxygen, sulphur, or =N-R 4 , R 1  and R 2  are divalent C 1 -C 3 O hydrocarbon groups, R 3  and R 4  are each hydrogen, a C 1- C 30  hydrocarbon group, acyl or -NR 5 R 6  in which R 5  and R 6  are hydrogen, a C 1 -C 30  hydrocarbon group or acyl or R 5  and R 6  together with the nitrogen atom to which they are attached form a 5- or 6-membered heterocyclic radical which may contain additional hetero atoms; the group in which W<SP>1</SP> is as defined for W above; the groups or in which R 7  is hydrogen, halo, a C 1 -C 30  hydrocarbon group or the group as defined above, acyl; cyano; nitro; or halogen. In addition one or more pairs of Rs from each of two non-adjacent nuclear carbons can represent a carbon to carbon linkage, a divalent radical, e.g. alkylene or oxy or a pair of Rs on the same carbon atom can represent a divalent aliphatic group (e.g. alkylene) both valences of the group not arising from the same atom in the group. The hydrocarbon groups referred to above may also carry substituents. The acyl groups referred to may be derived from organic acids by removal of an OH or SH group, e.g. from organic phosphorus acids, organic thiophosphorus acids, organic sulphur acids, carboxylic acids and thiocarboxylic acids. A preferred group of starting materials are those obtained by the reaction of a conjugated diene with an ethylenically or acetylenically unsaturated compound by the Diels-Alder reaction. The reaction of the unsaturated cycloaliphatic compound with sulphur results in a mixture of products in which divalent sulphur atom(s) link the cycloaliphatic nuclei together and in which the sulphur atoms may form part of a ring. Numerous examples are given of the preparation of various Diels-Alder condensation products and the sulphurization of these.

Filed: 1965-11-05
Abstract: 1,126,618. Endless conveyers. ROSEFORGROVE Ltd. 6 Feb., 1967 [5 Nov., 1965], No. 47049/65. Heading B8A. Apparatus for feeding batches of unwrapped biscuits to a flighted conveyer 5 comprises a horizontal platform 1 to receive the biscuits 15 and a shield 3 extending around the platform to retain the biscuits thereon. The platform and the shield are rotatable about a shaft 2 by independent drive means to deposit said biscuits on a stationary support surface 6 between the flights 14 of the flighted conveyer. The independent drive means each comprise a friction clutch (27), (28), (Fig. 3, not shown), mounted on a common shaft 31 driven from a power source which also drives the conveyer, thus ensuring synchronization between said conveyer and the feed mechanism. The clutches in turn are connected by chains 45, 46 to their respective part of the feed mechanism and are controlled by stops 38, 39 in engagement with arms 41, 42. The shield drive is held stationary by abutment with a stop 39 on the arm 42 until the start of a cycle, whereby the arm 42 is moved clear of the stop by a cam (not shown) and the shield then completes one revolution. In the position shown the stop 38 abuts the arm 41 and the platform is held in a stationary horizontal position to receive the biscuits, on rotation of the arm 41 in an anticlockwise direction the stop 38 moves around the face thereof and allows the platform to rotate in a clockwise direction. As the feed mechanism thus rotates the weight of the biscuits is transferred to the shield until the platform reaches a vertical position wherein the shape of the arm 41 is such as to temporarily stop the platform which thus serves to push the biscuits from the shield on to the stationary support surface 6 in the path of the oncoming flights. The platform then rotates to complete the cycle.

Abstract: 1413117 Laminates J REARDON 19 Jan 1973 [21 Jan 1972 13 Oct 1972] 2923/72 and 47325/72 Heading B5N [Also in Division B2] A composite wall board comprises a sheet of wallboard which is plasterboard, plywood, hardboard or asbestos board, bonded to a layer of expanded plastics material, e.g. polystyrene, totally enclosed in a coating of bituminous material which also bonds the layers together. In Fig. 2 a strip of expanded polystyrene of fully compressed form is fed from reel 4 through dip-tank 5 supplied with bituminous material from vessel 7 and is pressed by roller 2 against plasterboard fed from a supply stack by conveyer 1. The polystyrene strip is parted by cutter 9 at the junction between two consecutive plasterboards and bituminous material applied to the cut edges by an end-sealing device coupled to the cutter. Fine grit or other particulate material is deposited on the coating while it is still wet from hopper 10 and becomes embedded in the coating and the composite board is then dried by passage through drying oven 3 having infra-red heaters 11. Plasterboards may be treated in pairs by duplicating the supply reel, dip-tank, pressure roller, cutter and gritter beyond the arrangement of these members in Fig. 2 and interposing an inverting mechanism between these two sets of members so that after parting and edge sealing the pair of plasterboards with one layer of coated polystyrene on one of the boards is inverted as a whole to bring the other plasterboard to the upper position ready for the application thereto of the second strip of coated polystyrene and passage under the second pressure roller with subsequent parting off and edge sealing of the second strip. The pair of composite boards is then conveyed into the drying oven and not separated until required for use.

A control part 11 having a slot 10 co-operating with a pin 9 on an arm 8 extending from the part 4 is adjustable to limit the working stroke of the means 1, since the working stroke imparted by the cam 13 is bigger than the biggest stroke which the slot 10 allows for the part 4 and the means 1. An elastic member or hairpin shaped spring 17 is provided to act as an abutment for the pin 16 and take up any excessive stroke. The driving member 14 could be on lever 21 which rotates on a shaft 20, Fig. 2, and could co-operate with part 4 through a lost motion connection 16-18. Alternatively an elastic member (not shown) could be mounted on the lever 21 to co-operate directly with the part 4. An oscillating pendulum 23 is also provided to operate on the part 4 in the case where the distance dependent drive of the recording device is interrupted or disturbed.
