Abstract: 1,106,626. Laminates. BERK Ltd. 31 March, 1966 [12 April, 1965], No. 15533/65. Heading B5N. [Also in Division E2] A structure comprises a support member to which there is secured at least one anti-slip member, the or each anti-slip member comprising a metal or alloy substrate 10 or which there is superposed a first layer 12 of material which adheres to the substrate and to a multiplicity of irregularly shaped solid particles 13, the particles projecting from the layer 12, and a second layer 14 of material which adheres to and covers both the particles 13 and the exposed portions 15 of the layer 12 disposed therebetween, the thickness of the layer 14 being such that the particles cause the external surface 16 of the layer 14 to be formed with a multiplicity of irregularly shaped protuberances. The substrate 10 may be of steel which is grit blasted before the layer 12 is applied to it, the particles 13 may be of flint, granite grit, aluminous oxide or metal slag, and the layers 12 and/or 14 may be of natural organic plastics materials, e.g. bituminous plastics, or synthetic organic plastics materials e.g. synthetic thermoplastics materials such as polyamides, e.g. nylon, and polyolefines, e.g. polyethylene and polypropylene, or thermosetting resins e.g. epoxy or alkyd resins. The layers 12, 14 may be of the same or different materials and in the latter case the melting or softening point of the material of the layer 12 is higher than that of the material of the layer 14. The layer 12 may be applied to the substrate 10 by heating the latter to a point above the melting or softening point of the material to be used and applying the material in powder form e.g. by dipping the heated substrate in a fluidized bed of the material, or by blowing or sprinkling the powdered material on the heated substrate. Alternatively the plastics material is heated above its softening or melting point and the substrate coated by dipping, or the plastics material is flame sprayed on to the substrate. The particles 13 are forced under pressure into the layer 12 while the latter is still plastic. The structure of the invention may be a clamp whose jaws are constituted by the anti-slip members, a deck, floor, path, vehicle footplate, or step.

Abstract: 1,041,073. Feeding webs. HINDLE SON & CO. Ltd. April 15, 1964 [April 19, 1964], No. 15595/63. Heading B6B. [Also in Divisions B8 and D2] A felt tensioning roller 11 in a paper machine lies in a bight or fold of the felt 21 and is arranged to exert a constant tension on the felt through the action of an air motor 15 which is maintained under constant load. The roller 11 is supported at its ends in bearing assemblies 9 which are mounted on chains 8 which pass around sprockets 12. A shaft 17 connects two of the sprockets 12 so that any movement of the roller 11 takes place concertedly through movement of the chains 8. The air motor 15 is drivingly connected with the shaft 17 through a gear-box 16 and a chain and sprocket drive 19, 20. Under normal conditions the air motor is stalled and creates a constant tension in the felt 21. If, in use, the felt slackens or tightens, the air motor causes a corresponding movement of the roller 11 which comes to rest again at a position in which the felt tension is restored to its original value. The air supply to the air motor may be regulated by a relieving type regulatory valve in order to regulate the tension actually created in the felt.

Title: Improvements in or relating to moulds and mould components
Inventor: BICKERDIKE ROBERT LEWIS
IPC: B22C9/10
Filed: 1965-04-14
Abstract: 1,147,519. Carbon mould. NATIONAL RESEARCH DEVELOPMENT CORP. 8 July, 1966 [14 April, 1965], No. 15933/65. Heading C1A, [Also in Divisions B3 and C3] A mould having a casting face or a component part of such a mould comprises a bonded mass of carbon fibres wherein the majority at least of the bonding is by non-fibrous carbon. The carbon fibres may be graphite fibres. The mould or part thereof is formed by consolidating in a container a mass of resin-treated carbon fibres or a mixture of carbonizable fibres and a resin, removing the shape from the container and heating under non-oxidizing conditions to carbonize the resin, and, if necessary, the fibres. The porous article produced is strengthened and rendered impervious by being heated in a hydrocarbon atmosphere in a furnace when pyrolytic carbon is deposited in the pores. The preferred resin is a phenol-formaldehyde resin which is dissolved in methylated spirits in order to treat the fibres. The resin may be hardened by the addition of hexamethylene tetramine. A fugitive filler e.g. polyethylene powder, may be added to the mixture to assist in the consolidation of the mass, said filler evaporating during carbonization. Other fillers may be present in the raw fibre material prior to carbonization or may be added to give desired properties to the product. Examples are the filler in a paper which is carbonized to give the carbon fibres, or other fillers like powdered carbon, graphite or sand. In use the mould of the invention may be backed with a metal moulding box filled if desired with sand, carbon, or a mixture thereof as backing support for the mould. The material may be used to form a die in continuous casting and by using appropriate fillers it may be prepared so that properties of different parts of the die are different and are suited to the particular function and environment of each part. The material may be graphitized if desired.

IPC: B25B27/14
Filed: 1962-04-27
Abstract: 932,039. Making helical wire inserts; coiling; screwing. HELI-COIL CORPORATION. April 27, 1962, No. 16111/62. Classes 83 (2), 83 (3) and 83 (4). [Also in Group XXV] A method for lining tapped holes in light metal, plastics, wood or the like by means of profiled wire pieces is characterized by the steps of inserting the end of the profiled wire in a diametrical slot in the head end of a rotatably and axially shiftably journalled, screw-threaded mandrel, rotating said mandrel thereby bending said wire into the thread convolutions of said mandrel, and screwing the wire while the mandrel advances into the tapped hole of the insert to be lined. Wire 32, e.g. of steel or artificial material and of diamond or pear-shaped section, issuing from a rolling mill, extruding or injection means, or wire reel, is inserted by rollers 68, through guides 70 and groove 30 in a block 26, and into a diametral slot 62 in the end of a threaded mandrel 22. The mandrel 22 is then rotated and, engaging a screw-thread 28 in the block 26, moves downwardly through a plate 34 into a tapped hole 38 in a workpiece 40 pressed against the plate 34 by a spring-urged housing 44. As the mandrel 22 rotates and descends it wraps the wire 32 around itself in the form of a helix and screws it into the hole 38. When the end of the mandrel 22 depresses a centring ball 58 a limit switch 54 causes the mandrel to be rotated in the opposite direction so as to withdraw leaving a helical wire insert in the hole 38, and switch off its driving motor. The wire 32 is cut from its supply during or before coiling by a knife 76. The mandrel may be advanced by spring means. The wire 32 may be notched near its end by a tool 78 so that the part of the wire from the slot in the mandrel may be readily broken off.

Title: Improvements in the treatment of stitching or sewing thread for the soles of footwear
IPC: D05B67/00
Filed: 1934-05-31
Abstract: <PICT:0440410/IV/1> Thread for use in stitching footwear is impregnated between the supply bobbin and the stitching machine by pasage through a bath of a cold composition of rubber latex, an emulsion of soot and a cold vulcanizing agent, and a filler such as potato dextrin, powdered rotten stone, or the like.  The soot is preferably derived from burnt leather but lamp black may also be used; the bath is preferably prepared by first mixing the soot emulsion with the latex, previously diluted with water, at about 60 DEG  C., adding the filler during the cooling off period, and subsequently churning the mixture at about 20 DEG  C.; common salt or alum may be added to the soot emulsion and latex before the addition of the filler.  The tendency of the latex to coagulate may be retarded by the addition of formaldehyde.  Excess composition may be removed from the thread by passing it through a stripping device as it leaves the bath.  A suitable adjustable stripper comprises a split rubber sleeve e mounted in a tubular member a which is screwed into a boss b in the side of the bath, which may be the usual wax-pot.  The thread passes through the rubber sleeve, which removes excess composition.  By screwing in the cap h, the rubber sleeve is compressed against the shoulder d and more composition is removed.

Title: Process for the separation of olefinic hydrocarbons
IPC: C07C7/11
Filed: 1963-04-26
Abstract: Olefins are separated from mixtures also containing saturated hydrocarbons and hydrogen by absorption of the olefins in an aqueous solution of silver fluoborate or fluosilicate containing sufficient pentavalent vanadium ions to prevent reduction of the silver salt and sufficient hydrofluoric acid to maintain the pentavalent vanadium in solution.  Preferably, vanadium pentoxide is dissolved in hydrofluoric acid and added to the silver solution to give a vanadium concentration of 0.04-0.4% by weight and a 0.3-3 molar hydrofluoric acid solution. The solution is preferably heated to boiling-point until it turns yellow. The solution may also contain hydrofluoboric acid or hydrofluosilicic acid and a secondary metal having a charge to ionic radius greater than 1 as described in Specification 906,688. The titravalent vanadium formed may be reoxidized to the pentavalent state with oxygen, hydrogen, peroxide or nitric acid and re-used.

Abstract: 545,260. Multiplex systems. STANDARD TELEPHONES & CABLES, Ltd., and BEATTY, W. A. Nov. 15, 1940, No. 16541. [Class 40 (iv)] The complex wave formed by the channels of a multiplex tone telegraph system is transmitted by means of a pulse modulation system in which the durations or times of occurrence of pulses are characteristic of wave amplitude. Selection of the tone frequencies presents difficulty owing to interference due to beats between tone frequencies and the pulse frequency, but frequencies less than <SP>1</SP>/ 5 th of the pulse frequency are free from interference which, however, is present in increasing levels at this and higher sub-multiples “, 1/3, and ¢ of the pulse frequency. With a pulse frequency of 2000 per second, which in general permits of modulation by frequencies up to 1000, 3 tones maybe below 400 cycles per second (<SP>1</SP>/ 5 th) but in the case of tones above this frequency, the sub-multiple of 2000 should be avoided. At 400 per second interference is tolerable.
