Title: Improvements in or relating to sound damping compositions
Inventor: PURKIS ANTONY COLLINS
IPC: D06N5/00
Filed: 1960-06-09
Abstract: A sheet or pad, capable of being fused to a metal sheet by heating for the purpose of damping sound and vibrations of the metal sheet, comprises an intimate mixture of bitumen and/or a resinous sound-damping material, and a granular or powdery filler material, having on the side thereof remote from that side which is to contact the metal sheet a layer of a material which is sufficiently resistant to a hydrocarbon solvent to prevent the solvent from leaching out the bitumen and/or resinous constituents of the sound damping material when a metal sheet to which the sheet or pad is adhered is dipped or immersed in a bath of the solvent for a short time.  The sound-damping material may comprise a coumarone, indene, coumarone-indene, styrene-indene, or cyclopentadiene resin, a resin derived from homologues of such a resin, or a mixture thereof with, if necessary, a plasticizer or softener.  The filler material, which may be present up to 5 parts by weight per part of resin and/or bitumen may be clay, mica, whiting, slate powder, sand, barytes, talc, ground asbestos, ground granite, silica, carbon black, wood flour or cork.  The thin layer of solvent-resistant material may have a dry weight of between 4 and 7 grammes per square foot, may be prefabricated and applied to the layer of sound-damping material, e.g. paper or p  regenerated cellulose film, or formed on the layer of sound-damping material by depositing thereon a film either from a solution or a dispersion, e.g. rubber latex dispersion with or without vulcanizing ingredients, or a synthetic resinous material such as polyvinyl acetate or chloride, butadiene-acrylonitrile, butadiene-styrene, or a copolymer of vinyl acetate and alkyl maleate.

Title: Improvements in or relating to methods of manufacturing hollow glass objects closed at one extremity
IPC: C03B23/09
Filed: 1956-07-03
Abstract: 809,843. Glass forming and composition. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 3, 1956 [July 6, 1955], No. 20594/56. Class 56. One end of a glass tube is closed in the production of hollow objects, e.g. lamp bulbs, by heating the tube end by a succession of burners, the first, 18, of which is presented at right angles to the tube axis and the last, 19, in alignment therewith, the intermediate burners becoming progressively less inclined to the axis, the effect of the heating being to close the end except for an opening 21 of less than 1 mm. diameter through which the combustion gases of the burner 19 are directed. The flame temperature of the burner 19 is such that the surface tension of the glass overcomes its viscosity and forms a uniform seal along the opening 21. The burner 19 may be supplemented by a burner 23. The tubes may be carried, for rotation, on a frame 16, the first burner 18 being horizontal and the last burner 19 being vertical. The closed tube part is slowly cooled in the normal manner, burners being provided for this purpose, and separation from the main tube. Stock may be effected by contact with a cold object, after which the tube stock is moved axially forward for a new cycle of operations. The sealed end of the tube may have a shape determined by the speed of rotation on its own axis, and the atmospheric pressure within the tube. If the rotation is slow, the seal is thick in the centre, and if fast is thick at the periphery. The inner surface of the seal is concave, flat or convex according to the pressure, sub- or super-atmospheric, within the tube, and the seal may be shaped for use as a lens. The burners may be arranged to rotate around stationary tubes, and the tubes may be processed in a horizontal position.

Title: Method of and apparatus for moistening yarn
IPC: D06B1/00
Filed: 1936-07-25
Abstract: <PICT:0478219/IV/1> In moistening or conditioning yarn a quantity of liquid less than that required to saturate it but in excess of the amount to be retained in the yarn is introduced within the body of the yarn and the excess of liquid is expelled centrifugally and collected. The body of yarn is supported on a rotatable support which is rotated at a speed of from about 2000--6000 revolutions per minute, preferably 4500--5000 revolutions per minute, until the predetermined excess of liquid is expelled from the yarn.  The optimum speed of rotation depends on a number of variables and is determined empirically, the period of treatment also being determined empirically.  Two forms of apparatus which may be employed in carrying out the above method are described; in one the charge of liquid is introduced into the body of the yarn with the aid of pneumatic or hydraulic pressure, while in the other, it is introduced under gravity before or during rotation of the yarn.  The former apparatus is shown and comprises a hollow conical support 11 provided with perforations 55 resting on, and spaced by shoulders 13, 14 from, a holder 12 adapted to be rotated at high speed by an electric motor 45 by a belt 46 and pulleys 47, 48.  The space 15 between the support 11 and holder 12 communicates with a central bore 17 through a series of passages 16, and the charge of liquid is supplied under pressure to a tube 37 which communicates with the bore 17.  A basket 18 encloses and rotates with the coneshaped body of yarn 10 which is placed on the support 11, a spring plunger 54 in a hinged cover 51 holding the support against a water-tight seal lining 64 of rubber or other yielding material.  The liquid supplied is distributed along the whole length of the package 10 and owing to the high speed of rotation passes through it before it is wholly absorbed, excess liquid being collected in a fixed housing 49 supported on the machine framing 27 by pillars 50.  The second form of apparatus is similar except that the hollow cone-shaped body of yarn is inverted and held in a basket of corresponding shape but with a ribbed inner surface. The measured quantity of liquid is admitted under gravity into a perforated conical-shaped support placed in the middle of the package.  Specification 25525/98, [Class 15], is referred to.
