Title: Diaphragms
IPC: B29C70/06
Filed: 1969-11-27
Abstract: 1330465 Moulding diaphragms DUNLOP HOLDINGS Ltd 17 Nov 1970 [27 Nov 1969] 58070/69 Heading B5A [Also in Division B2] A textile reinforced resilient diaphragm is produced by covering a suitably shaped former with a flexible sheet material and applying textile reinforecement to form part of the diaphragm to the flexible material, the textile reinforcement being sprayed with a natural or synthetic or blended natural and synthetic rubber solution containing the compounds necessary to form an aldehyde condensation resin. The reinforcement may be applied to the flexible material after spraying or before spraying. The textile material may be in the form of yarns or cords and may be formed from a natural, regenerated or synthetic material preferably nylon. Suitable rubbers include natural rubber, butadiene-styrene rubbers, polychloroprene and ethylene-propylene rubbers. The compounds necessary to form an aldehyde condensation resin may be aldehydes or aldehyde generators (e.g. hexamethylene tetramine) and aromatic hydroxy compounds (e.g. resorcinol, p, p-isopropylidene diphenol and 1,5- dihydroxy naphthalene) or melamine or urea. The solution may also comprise silica or a silicate, fillers, carbon black, extender oils and vulcanizing agents. As shown in the Figure, a forming reel 1 comprises two halves, one half being rotatable with respect to the other half ú and the halves being mounted so the rotation of the rotatable half can cause the two halves to move into contact. Flexible material in the form of a suitably shaped calendared sheet of uncured or semi-cured natural or synthetic rubber is applied to the forming reel and longitudinally extending textile filamentary material is distributed around the forming reel to form a tubular reinforcement sock. The reinforcement sock is sprayed with the rubber solution and one half of the forming reel is rotated relative to the other half causing the cords overlying the hyperboloid portions 6, 7 of the forming reel to become embedded in the flexible material. The resultant tube is then removed from the forming reel and a bead wire ring is applied externally over the centre of the tube. One end of the tube is drawn back over the bead wire ring and over the other end of the tube, which other end may be carried on a shaping former. A larger bead ring is fitted and the two plies turned back over this ring. The assembly so produced is then moulded under heat and pressure to produce a rolling lobe diaphragm, operating between parallel or tapered rigid sleeves or pistons for use in vehicle suspension systems.

Abstract: 1346576 Foundry moulding processes DEFENCE SECRETARY OF STATE FOR 19 April 1971 [3 April 1970] 15817/70 Heading B3F [Also in Division B5] A foundry mould block is prepared by coating an expendable layer 13 on to a pattern 14, applying refractory material to the thus-coated pattern (14, 13) to form a block 11, removing the expendable layer 13, separating the block 11 from the pattern 14 by a distance 15 and injecting between the block 11 and pattern 14 a facing composition of a finely-divided refractory material dispersed in a wax. The block 11 with its facing is removed from the pattern 14 and fired in a kiln to evaporate the wax and harden the facing. After casting, the facing is removed from the block 11 with the casting so that the block 11  may be refaced for further use. Before moulding the pattern 14 is covered with an expandable layer 13 of wax, plaster, modelling clay, selfadhesive wax sheet, rubber or thermoplastic sheet and the block 11 is moulded by pouring a refractory cement-like mixture over the coated pattern 14 (see Division B5) or by tamping a refractory aggregate/Na silicate mixture around the pattern 14 and hardening with CO 2 . To provide chilling regions in the mould, SiC or chrome iron ore may be added locally to the block 11 and to provide heat-insulated areas bubble Al 2 O 3  or porous grog may be added locally to the block 11. After moulding the expendable layer 13 is fired away and the pattern 14 and flash sides, but not the block surface covered with parting agent. The pattern 14 is spaced from the block 11 by a distance of 2-3 mm. for patterns of area up to 1000 cm.<SP>2</SP>, up to 4 mm. for larger patterns, and a liquid wax/refractory composition injected between the pattern 14 and block 11 to form a facing layer (see Division B5). After separating the faced block 11 from the pattern it is fired to drive off wax and to preheat the mould to pre-casting temperature. Facing compositions suitable for use with steels and other high temperature alloys and for use with aluminium, copper and other lower temperature alloys are disclosed in the Specification. Cores may be made by injecting a liquid wax/  refractory composition about an insert and stoving the moulded core to drive off the wax and to assist hardening.

Title: Apparatus and method for reclaiming useful oil products from waste oil including hydrogen injection
IPC: B01D1/00
Filed: 1998-10-23
Abstract: An apparatus and method for reclaiming a useful oil product, from waste oil provides an evaporation chamber in which waste oil is heated and vaporized, preferably at a temperature which causes some cracking of the oil. Hydrogen is injected into the vaporized oil, so to cause saturation of at least some of the olefins in the vaporized oil. The vaporized oil is then condensed and recovered as a useful oil product. The apparatus operates at substantially atmospheric pressure, or a pressure only slightly above atmospheric pressure. Hydrogenation of the vaporized oil stabilizes the recovered oil, and prevents formation of tars and other heavier hydrocarbons, which can cause difficulties in use of the recovered oil.
