Title: Improvements in vinyl chloride copolymers
IPC: B29C71/04
Filed: 1958-12-31
Abstract: Pre-shaped resinous copolymers of 95 to 50 wt. per cent vinyl chloride and 5 to 50 wt. per cent of one or more copolymerizable monomers selected from:-(a) di-C4-20 alkyl maleates; (b) vinyl esters of C3-20 fatty acids; (c) vinyl C18-30 alkyl ethers; (d) C1-20 alkyl acrylates; (e) C3-20 alkyl methacrylates are cross-linked by subjecting the formed composition, in the absence of any ethylenically unsaturated plastifying agent, to 5 to 50 watt-hours/lb. of ionizing radiation.  Ionizing radiations specified are X-, gamma-, and beta-rays, electrons, neutrons, protons and alpha particles. Preferably the resin composition, contains 5 to 80 parts of a filler, e.g. carbon black or silica, per 100 parts of resin.  In examples the effect of the irradiation treatment on compositions of various of the specified resins is contrasted with that on polyvinyl chloride vinyl chloride/vinyl acetate copolymer, and copolymers of vinyl chloride with monomers homologous with, but of shorter chain length than, those specified.  The compositions also contain calcium stearate, dioctyl phthalate and carbon black or silica.  One example shows the effect of the treatment on the insulation of copper wire insulated with a terpolymer of vinyl chloride (80)/dilauryl maleate (15)/vinyl stearate (5).

Patent GB-925654-A (GB)
Title: Treating fabrics
Inventor: SMITH FREDERICK RICHARD
IPC: D06B5/00
Filed: 1960-12-09
Abstract: A process for reducing the weight of fabrics comprising polyester fibres by treating with a caustic alkali metal hydroxide solution is characterized by passing the solution through substantially the whole piece of fabric wound, e.g. on a perforated or permeable beam, so that substantially the whole length of the fabric is simultaneously percolated by the solution, recirculating the solution for a predetermined time and/or until a predetermined pressure drop and desired weight loss has occurred. The fabric is preferably wound with a small traverse motion so as to give a staggered overlay of the selvedges and, to prevent thread slippage, the fabric may be slightly embossed before the caustic treatment.  After the caustic treatment the fabric may be dyed and then rinsed whilst still on the beam.  The caustic solution may contain between 0,5% and 5% sodium hydroxide and from 0,005 to 0,5% of an accelerator selected from quarternary ammonium salts.  The volume of flow of the solution is preferably adjustable so that the pressure drop can be determined at the initial volume of flow.  Specifications 652,948 and 917,497 are referred to.ALSO:<PICT:0925654/IV(a)/1> In a process for reducing the weight of fabrics comprising polyester fibres by treating with a caustic alkali metal hydroxide solution the fabric is wound, for example, on a perforated or permeable beam, the solution is passed therethrough so that substantially the whole length of fabric is simultaneously percolated by the solution, and the solution is recirculated for a predetermined time and/or until a predetermined pressure drop and desired weight loss has occurred.  As shown polyester fibre fabric 1 is uniformly wound, with a traverse motion to give a staggered over-lay of the selvedges, on a perforated beam 2 having flanges 3, 4 to blank off parts of the beam not covered by fabric, and is mounted in a vessel 5 which is connected by conduit 6 to a tank 7 having heating means 8.  Another conduit 6a from tank 7 leads via a pump 9 to the open end of the perforated beam 2.  A pressure gauge 10 is connected in conduit 6a and preferably a flow meter is fitted at A. In operation water in tank 7 is heated and by means of pump 9 is pumped through the perforations in beam 2 so as to percolate through the entire fabric 1. When the fabric is fully soaked and air has been expelled caustic soda solution is charged into the tank to make up the required concentration, a reading on pressure gauge 10 is noted and pumping is continued until the required pressure drop has occurred or for a predetermined time. If a flow meter is fitted at 'A' the flow may be adjusted by a valve in the system to maintain the flow constant and thus compensate for the action of the caustic soda solution in dissolving the fabric.  Specifications 652,948 and 917,497 are referred to.

Title: Improvements in or relating to methods of and materials for treating hair
IPC: A61K8/92
Filed: 1960-12-12
Abstract: Crimp, Fuzz or other curl is removed from or reduced in hair by treating it with a cream or paste containing beeswax, a steerate and a thioglycolate, e.g. ammonium thioglycolate, which holds the hair under tension while reacting with the outer layer of the hair to change its natural set.  After the treatment any residual chemical materials may be removed by washing and a neutraliser applied.  The stearate is preferably glyceryl monostearate and the composition may also contain suitable wetting agents and a conditioner for the hair. The thioglycolate may comprise 30-38% by weight of the composition. The hair may be subjected to the action of the composition for not less than 10 minutes and not more than 25 minutes.  In the preparation of a cream the glyceryl monstearate, beeswax, conditioner for the hair and wetting agent may be first mixed at an elevated temperature approaching the boiling point of water, cooled to a lower temperature and mixed with ammonium thioglycolate in a 40% by weight aqueous solution, the mixture then being rapidly stirred until a cream is formed and then being packed in a collapsible tube.

At end-wall 14 there is provided an annular cam surface 30 having at least two areas distant from the end-plate 14 and at least two areas closer to the end-plate 14. Bores 18, parallel to the drive shaft 36 are formed in the cylinder block 16 to contain pistons 32, 34, each provided with a cam follower surface (68) engaging cam surface 30. At the other end-wall 12 there are located inlet (72, 74) and exhaust (76, 78) ports and a sparking plug (80) (all not shown). The cylinder block 16 rotates with the shaft 36. In order to maintain the cam follower end (68) against the cam surface 30, the piston and cylinder bores are stepped and a quantity of pressurized gas is trapped at the piston shoulder. A duct (86 not shown) may lead from the combustion chamber at the top (leftward) end of each piston to the shoulder to direct exhaust gases to the shoulder and replenish leaked gases. Cooling.

Abstract: 1,010,547. Bearings. COMMISSARIAT A L'ENERGIE ATOMIQUE. Nov. 7, 1963 [Nov. 14, 1962], No. 44003/63. Heading F2A. A fluid bearing has a circumferentially-spaced series of bearing elements surrounding a shaft, the elements being mounted so as to allow individual radial displacement towards and away from the shaft, a pressure chamber defined in each element and at least one orifice formed therein which communicates with the pressure chamber, pressurized fluid being supplied to all of said pressure chambers. In an embodiment, a shaft 23 is mounted in fluid bearings 1, 2, which are separated by a tubular member 3 having weight-reducing cut-outs therein, the whole being surrounded by a cylindrical casing 4. The latter is screwthreaded internally at both ends to receive a retainer 5 which retains the bearing 1 and to receive a member 6 which retains the bearing 2 and carries a storage tank 25 which is supplied with pressurized fluid, by means not shown. Each bearing has a housing 15 having a wall which, along with the casing 4, forms an annular reservoir 14; each housing 15 has a base with vents 21 therein; and each housing 15 has a cover-plate 16 secured thereto, the latter also having vents 21 therein. Each bearing element 8 has a radially-inner part 9 which is recessed to receive a radially-outer part 10, a pressure chamber 11 being formed therebetween. The parts 10 each have a pipe 13 held thereby and passing therethrough, the pipe 13 communicating with a respective hole in the reservoir 14. The radial outward movement of the elements 8 may be restricted by a ring 7 of elastic material which is received in grooves 12 of the members 10; alternatively, each element may be supplied with an individual spring, not shown. In use, pressurized fluid is supplied from the tank 25 to the annular reservoirs 14 via pipes 27, 28 and the fluid is passed to the individual pressure chambers 11 through a pipe 13. The pressurized fluid is then conveyed to the shaft 23 via orifices 20 in the members 9. Any pressurized fluid which enters the annular chamber formed by the inner wall of the reservoir 14 and the outer walls of the members 10, escapes through vents 21. The shaft 23 may be supported axially by pressurized fluid supplied from the tank 25 to a chamber 26 in the member 6.
