Title: Improvements in or relating to compositions for covering surfaces of roads and the like
IPC: E01C7/32
Filed: 1932-11-23
Abstract: Compositions for covering the surfaces of roads and the like are prepared by the admixture of aqueous compositions of flocculent or precipitates with small road metal such as granite chippings or sand. In an example 7 parts of an aqueous composition of a flocculent precipitate are mixed with 95 parts of stone chippings in a cement mixer, and the product laid down as a surfacing material, which when dry resembles a tarmacadam road. It is stated that flocculent precipitates of rubber have superior adhesive properties to those of latex, since they have already passed through a stage corresponding to the ordinary coagulation of latex.  Specifications 219,635, 290,313, [both in Class 70], and 410,793 are referred to.

Title: Hydrocarbonyl thiosulphinates and the preparation thereof
IPC: C07C381/00
Filed: 1947-12-17
Abstract: Organic thiosulphinates of the formula <FORM:0654390/IV (b)/1> where R and R1 are hydrocarbon radicals, are made by treating the corresponding disulphide with an organic per-acid below 55 DEG  C., preferably in a solvent.  0.5-2.0 Molecular equivalents of the per-acid, preferably approximately one, are used.  Mercaptans may be used as starting materials, with intermediate formation of the disulphide in the reaction mixture. The two radicals in the disulphide used may together form an alkylene group or they may be alkyl, alkenyl, aralkyl, cycloalkyl, or aryl, examples of all of which are given.  Per-acids specified are perbenzoic, perphthalic, perfuroic, percamphoric, and peracetic.  The usual solvents are specified.  Where the radicals are secondary or tertiary alkyl radicals, irradiation with ultraviolet light is advantageous.  The products form disulphide condensation products containing amino and carboxylic groups with cysteine.  The products are bactericides and fungicides.  In examples: (1) perbenzoic acid is reacted with allyl disulphide, n-butyl disulphide, n-amyl disulphide, or ethyl tert-butyl disulphide; also (2) perphthalic acid is reacted with methyl disulphide; (3) perfuroic acid is reacted with ethyl disulphide; (4) percamphoric acid is reacted with n-propyl disulphide.  Also, benzyl alpha-toluenethiolsulphinate may be obtained from benzyl disulphide, cyclohexyl cyclohexanethiolsulphinate from cyclohexyl disulphide, and phenyl benzenethiolsulphinate from phenyl disulphide.  The Specification as open to inspection under Sect. 91 states that the radical R and R1 may contain nitro, hydroxyl, carboxyl, halogen, carbonyl, amino, cyano, or ether groups, or they may be heterocyclic radicals, or the sulphur atoms may form part of a ring.  This subject-matter does not appear in the Specification as accepted.

Title: Pigment compositions and their production
Inventor: BIRRELL PETER
IPC: C09B63/00
Filed: 1964-08-14
Abstract: Pigment compositions are prepared by mixing an aqueous mass of pigment of particle size 0.02-1.0 micron with an aqueous dispersion of a copolymer, prepared by emulsion polymerization 30-70 parts of styrene and 70-30 parts of a C1- 12 (preferably ethyl) acrylate or methacrylate, of particle size 0.02-1.0 micron, subsequently coagulating the mixture at a temperature ranging from ambient to the boil, removing the aqueous phase from the coagulum and drying and pulverizing the solid. The aqueous mass of pigment may be prepared by dispersing the pigment with a wetting agent, e.g. the sodium or potassium salt of dinaphthyl methane disulphonate, octyl or butyl naphthalene sulphonate or a sulphated alkyl phenol/ polyoxyethylene condensate.  Coagulation may be achieved by addition of hydrochloric acid or a salt and may be in the presence of an agent for improving the pigment texture, e.g. rosin or a cresol/formaldehyde resin.  The copolymer, which may be a terpolymer, e.g. styrene/n-butyl acrylate/2-ethylhexyl acrylate, may be produced using sodium N-lauryl sarcosinate as emulsifier. The pigment composition may be blended with polyvinyl chloride, polystyrene or an acrylonitrile/butadiene/styrene terpolymer. Examples describe the emulsion polymerization of styrene and ethyl acrylate using n-dodecyl mercaptan as chain transfer agent and potassium persulphate as catalyst. Numerous pigments consisting of organic colouring matter are exemplified under trade names.  The composition may be used to form an ink, by blending (1) with a vinyl chloride/vinyl acetate/ maleic anhydride terpolymer and methyl ethyl ketone, (2) with a zinc/calcium resionate and toluene, (3) with a chlorinated rubber and toluene.

Abstract: 800,353. Transformers. FOXBORO, CO. Nov. 29, 1955 [Dec. 8, 1954], No. 34183/55. Class 38 (2). A transformer for use in a capacity bridge measuring instrument comprises primary and secondary windings wound around a magnetic core, the secondary winding comprising two coils, the ends of the inner winding layers of which are connected together, the ends of the outer winding layers forming the secondary terminals. A magnetic core 21 of the transformer 10 is in the form of a toroid, a primary winding 23 being wound thereon so as to extend over the whole length of the core. A secondary winding 14 is next wound around the core 21 in the form of two spaced coils 16, 17, the inner ends of which coils are connected together to form a centre tap on the secondary winding, the outer ends forming the terminals 24, 25 of the secondary winding. Thus the distributed capacities of the secondary winding between the terminals 24, 25 and the centre tap 15 are substantially equal and low in value and therefore do not introduce appreciable error in the capacity bridge. The error is. further lessened by tapering the ends of the coils 16, 17. In order to eliminate electrostatic coupling between the primary and secondary windings an earthed electrostatic shield 22 is placed between them. The shield may be formed of brass or of a silver painted tape. In a further embodiment the primary winding and the two secondary coils may each extend over a different " third " of the magnetic core, the primary winding in this case being completely enveloped in an electrostatic shield.
