Abstract: 1282756 Heated hair rollers I LAING 5 June 1969 [6 June 1968 24 Sept 1968(4) 26 Sept 1968] 28528/69 Heading A4V A hair roller 1 has a container 31 enclosing at least one thermally chargeable heat storage mass 33, 34 comprising in admixture a hydrate which melts at the working temperature of the hair roller and a substance which is insoluble in the melt of the hydrate at the said working temperature whereby the heat storage mass maintains a non-flowable consistency. The walls of the container may be reinforced with a metal spiral (4) Fig. 1 (not shown) and an insulating air or foam plastic layer may be interposed between the container and an outer sleeve 35. Hair rollers are described containing barium hydoxide octahydrate or ammonium alum for heat storage and an alginate as thickening agent to reduce leakage in the event of the roller being punctured. In use the rollers are heated to melt all the hydrate before being placed in position in the hair. The heat is given out at a virtually constant temperature as the hydrate recrystallizes two concentric containers, the inner having a hydrate 33 of higher melting point may be used to provide a more constant heating temperature. The rollers are heated by apparatus having magnetic or mechanical means attaching the roller temporarily to a heating plate. The heat may be supplied by electrical means having a thermostat to control the temperature of the heater or by a previously heated hydrate as in the roller but which crystallizes at a higher temperature. The rollers may be provided with a tapered hydrate container with lubricated walls or a central spike 42 extending from the area of attachment to the heating apparatus in order that expansion of the hydrate on melting shall not distort the container. Hinged levers rotatably mounted on the rollers or a bar slidably and rotatably mounted on the roller may be provided to grip the hair.

Abstract: 1,224,166. Electro-depositing composite coatings; electro-forming. BRISTOL AEROJET Ltd. March 21, 1969 [Dec.21, 1967], No.28598/67. Heading C7B. In a method of electro-depositing coatings consisting of a metal matrix and included fibres of less than one inch length and having a similar orientation to one another, relative movement is provided during electro-deposition between the substrate to be coated and the electrolyte in the direction of desired orientation of the fibres. The process may be used for coating articles or for producing articles by electro-forming. The fibres may be of carbon, graphite, silicon carbide, silicon nitride, boron nitride, beryllium, tungsten or boron, and may be metal plated prior to use, and the matrix may be of nickel, cobalt, tin, copper or aluminium. The substrate may be of steel, of a non-ferrous or light alloy, or of plastics, glass, or composited materials rendered conductive by incorporation of a conductive material therein or by pre-coating with a conductive material. In the form shown a tubular componant 9 to be coated is suspended from a hollow rotary shaft 12 in an electrolytic bath 7 within container 1 having a concical bottom section 2. Electrolyte is circulated by means of suction tube 5, pump 3 and feed tube 4 in order to maintain the fibres in suspension. A cathode 8 is provided adjacent the wall of the container 1, and the workpiece 9 and stirrer 18 are rotated about supporting shafts 12, 17 by means of drive belts 14, 20 and pulley wheels 13, 19 respectively. Spiral electrolyte flow may be induced by introducing the electrolyte tangentially. The component to be coated may be degreased with trichloroethylene or acetone, areas masked which are not to be plated, and cleaned mechanically, e.g. with alumina shot, or with an acid pickle. Examples relate to deposition of carbon fibres in a cobalt matrix using a calicobagged cobalt anode and electrolyte comprising cobalt sulphate, sodium chloride and boric acid; and to deposition of silicon carbide whiskers in a nickel matrix using a rolled nickel anode and electrolyte comprising nickel sulphamate, nickel chloride and boric acid.

Title: Improved manufacture of refrigerator cabinets
IPC: F25D23/06
Filed: 1960-08-18
Abstract: 882,458. Moulding refrigerator cabinets. GENERAL MOTORS CORPORATION. Aug. 18, 1960 [Sept. 4, 1959], No. 28649/60. Class 87(2). [Also in Group XIII] A refrigerator cabinet is formed by coating the outer and inner surfaces of male and female moulds 149, 151 with successive layers of congealable resin and fibrous material to form the inner and outer shells 194, 190, juxtaposing the two moulds so that the shells are nested, and foaming a foam-forming resin 199 in situ between the moulds to adhere to the shells, the moulds being then removed. The layers may be sprayed, brushed or rolled on to the moulds. The inner shell 194 has a peripheral flange secured to the front edge of the outer shell and forming the front face of the cabinet. Shelf supporting ribs are formed on the inner shell by appropriate protuberances on the mould 149. A formation for receiving a lamp 62 is similarly formed. Various reinforcements 42, 84, 86 are secured to the shells before foaming. The foamforming resin may be an epoxy resin or a polyurethane, the included gas being one or a mixture of various halogenated saturated aliphatic hydrocarbons quoted in the Specification. The fibrous material may be glass, sisal or textile. The congealable resin, which may be translucent or coloured by pigments, may be of polyester, epoxy, phenolformaldehyde or vynil type or nitrocellulose. It may be loaded with aluminium or other metal in powder or flake form.
Patent GB-483706-A (GB)
Title: Improvements in or relating to the purification of fuel gases
IPC: C10K3/00
Filed: 1936-10-21
Abstract: 483,706. Gas-purifying processes. GAS LIGHT & COKE CO., HOLLINGS, H., HUTCHINSON, W. K., DOUGALL, G., and MORCOM, A. R. Oct. 21, 1936, No. 28675. [Class 55 (ii)] Combustible gases containing a small amount of oxides of nitrogen with conjugated diolefines and oxygen are passed before entering the holders but preferably after removal of any tar fog, through a reaction vessel of such a size that the nitric oxide is reduced to negligible amount by interaction with the conjugated diolefines and oxygen, any resulting resinous particles being removed in a later purification stage. The gas may be at 80-120‹ F. when entering the vessel to increase the velocity of reaction. With the normal concentration of diolefines in coal gas, the vessel is of such a size that 2-12 minutes are required for the passage of gas therethrough. Air is added if the oxygen content is less than that required for normal iron oxide purification. Deficiency of conjugated diolefines may be made up as by the addition of hydrocarbons, e.g. alpha-phellandrone, alpha-terpinene rubber spirit, or products obtained during recovery of benzole or cracking of petroleum. Or gases such as carburetted water gas or a coal gas richer in the diolefines may be introduced. Vanes, diaphragms, &c. may provide for a stagewise reduction in the nitric oxide and the gas is preferably caused to be in a state of turbulence in the vessel the surfaces of which may have a coating as of spirit varnish or paraffin wax. The vessel may be interposed between the oxide purifiers and the benzole washer or drying plant, or before the purifiers which then filter out the gummy products. Or the products may be washed out as by dilute alkali or removed by an electrostatic precipitator or a filtering bed. In an example coal gas is passed at 85‹ F. through an empty two-chambered cast-iron tower 20 ft. in diameter and 40 ft. high with internal surfaces painted with shellac varnish. Specification 465,959 is referred to.

Patent GB-287555-A (GB)
Abstract: 287,555. Kidde & Co., Inc., W., (Assignees of Mapes, D.). March 24, 1927, [Convention date]. Pressure-relieving devices for fluids.- A fluid pressure sealing device with quick emergency release for use, for example, with carbon dioxide containers for fire extinguishing means comprises a rupturable diaphragm element b exposed on its lower face to the pressure in the container and supported on its upper face by a hollow plunger e. The plunger is held up to the diaphragm by a pair of levers f, f<1> having a mutual fulcrum block f<5> to one side of the plunger axis, the outer ends of the levers being held together by a fusible detent link g. The area of the portion of the diaphragm left unsupported by the bore e<1> of the plunger e is such that the seal is maintained for the normal internal pressure in the gas container; the diaphragm, however, is ruptured to give emergency release to the gas in the event of an abnormal internal pressure arrising. If the supporting levers of the seal are released and the diaphragm is left unsupported for the entire area of the outlet a<3> the diaphragm will give way to the normal internal pressure to permit the discharge of the contents of the container. The release is obtained voluntarily by fusing the detent link g by means of an electric current through the leads i, i<1>, the adjusting screw f<4>, and the levers f, f<1>; or by mechanical means by a pull on a rod or cable h<2> which releases the detent g from the levers f, f'.

Title: Improvements in pit-props
IPC: E21D15/26
Filed: 1951-12-10
Abstract: 709,141. Pit props. SCHUBERT, A. Dec. 10, 1951 [June 9, 1951], No. 28829/51. Class 20 (2) A telescopic pit prop comprises an unthreaded upper part 2 which is keyed to a lower part 1 for axial non-rotatory movement only and is supported therein by a lock unit 24 having steep threads 24a engaging corresponding threads 1a provided internally on the lower part 1, rotation of the lock unit 24 within the part 1 under load being restrained by coupling it to a member 4 1 n o n - rotatably mounted in the part 1 by a permanently engaged friction clutch 30 and a disengageable claw coupling 46. The upper part 2 has tongues 27<SP>1</SP> engaging vertical keyways in the part 1 and rests on the lock unit 24 having an internal sleeve 36 non- rotatably secured therein. A bushing 39 extends through the unit 24 carrying at the bottom a flange 38 and at its upper end a nut 40 between which and an abutment plate 36" resting on top of the sleeve 36 is interposed a strong spring 28 which exerts the braking pressure on the multiple disc clutch 30 having its friction rings alternately keyed to the sleeve 36 and bushing 39. The flange 38 has on its lower face serrations or claws and is disposed opposite a serrated or claw clutch disc 41 which is secured against rotation by tongues 41'. The disc 41 is carried by a rod 25 extending through the bushing 39 and coupling and uncoupling is effected by lifting and lowering the rod 25 by means of a displaceable plate 45 or a rotatable eccentric. Thus the multiple disc clutch 30 is subject permanently to the pressure of the spring 28 and on excess loading of the prop rotation of the lock unit 24 and telescopic retraction of the upper part 2 occur by overcoming the braking action of the disc clutch 30. To remove the prop, the upper part 2 is lowered by lowering the clutch disc 41 by means of the rod 25 whereupon the lock unit 24 together with the disc clutch 30 as a whole rotate.

Title: Yarn and fibre containing synthetic elastomeric material and a process for manufacturing fabrics therefrom
IPC: D02G3/32
Filed: 1964-07-14
Abstract: A yarn comprises synthetic elastomeric fibres or filaments-for example of polyurethane-and water soluble polyvinyl alcohol fibres or filaments for temporary control of the elasticity of the elastomer during fabric formation.  As described a synthetic elastomeric filamentary yarn may be combined side-by-side with, be coiled around or be coiled by, or be twisted with a polyvinyl alcohol filamentary yarn which may be coloured.  The surface of the vinyl yarn may be raised, sueded, or grooved, or may be treated with a non-skid agent. The composite yarn may itself be coiled with a natural or synthetic thread and/or be bonded with a water-soluble sizing agent.  To form staple fibres, the bonded yarn is stapled, and the fibres crimped or curled by heat treatment if the vinyl constituent has latent shrinkability. The staple fibres may be blended with other synthetic fibres before or after crimping.  The elastomeric fibres may be "spot-adhered" to the other synthetic fibres by a water-insoluble sizing agent spot-applied to the bonded yarn before stapling. Fabrics described are a lace fabric made by embroidering a base cloth of polyvinyl alcohol with a composite yarn and dissolving out all the polyvinyl alcohol; a woven fabric formed from one composite yarn, or with the warp formed from two different composite yarns and the weft from a natural or synthetic yarn, Figs. 8 (2) and (3) (not shown); a flat-knitted fabric either composed of one composite yarn, or of two composite yarns and one natural or synthetic yarn, Figs. 9 (1) and (2) (not shown); and a warp knitted fabric made of two composite yarns and one ordinary yarn, Fig. 9 (3) (not shown).
