Patent GB-611642-A (GB)
Title: An improved manufacture of composite materials containing hydrocarbon copolymers and bituminous materials
IPC: C08L23/22
Filed: 1946-05-02
Abstract: Thermoplastic compositions are made by homogeneously compounding a bituminous material and a copolymer of intrinsic viscosity above 0.5 of an aliphatic mono-olefine and an aromatic mono-olefine, the aromatic mono-olefine content of the copolymer being from 20-80 per cent, prepared at a temperature below - 50 DEG  C. in the presence of a Friedel-Crafts catalyst.  The preferred aliphatic mono-olefine is isobutylene, others specified are isopentene and a pentene obtained by dehydration of sec.-amyl alcohol.  Styrene is the preferred aromatic mono-olefine, others are indene, methyl styrenes and dihydro-naphthalene.  Listed bituminous materials include natural and petroleum asphalts, cracking coil tars, coal tar, wood tar and pitches.  Asphalts which have been refined, e.g. by distillation, steam reduction, air blown and oxidized, may also be used.  If desired, the bituminous material may be dissolved in kerosene, toluene, aromatic petroleum solvents, benzene, petroline or in aqueous emulsion.  The composition may also include polymeric materials not normally compatible with asphalt, e.g. polyisobutylene, polymethyl and polylauryl methacrylates.  Optional additions include clay, sand, limestone dust, limestone or coarser mineral aggregates, asbestos, hair, cotton and linseed oil.  The addition of the copolymer to bituminous material improves its toughness, flexibility, oxidation resistance, low temperature flexibility and reduces the cold flow.  The compositions may be calendered, extruded or cast or used for weather-resisting coating compositions, being applied in solution in a volatile solvent or in a heat-softened condition and, if desired, covered with roofing grit.  They may be used for water-proofing concrete, e.g. building foundations, paving roads, caulking purposes, e.g. building joints and expansion joints in concrete surfaces, for water-proofing single sheets of paper, bonding sheets of paper together or for bonding paper to metal foils, e.g. aluminium foil (see Group VIII).  Insulating material, e.g. rock and glass wool, may be bonded to craft paper with the compositions.  They may also be used for lining storage battery containers and for the preparation of printing inks.  Specification 513,521 is referred to.

Title: Improvements in or relating to code comparators
IPC: H04L25/04
Filed: 1951-06-06
Abstract: 730,854. Digital electrical calculating apparatus. STANDARD TELEPHONES & CABLES, Ltd. (Materiel Telephonique Soc. Anon.). June 6, 1951, No. 13417/51. Class 106 (1). [Also in Group XL (b)] Apparatus for comparing characters in a multi-condition code in which each code element is expressed as one of a plurality of electrical values, e.g. potentials, comprises a plurality of test devices, each individual to one set of corresponding code elements of the characters to be compared, and each adapted when a set of code elements applied thereto have a predetermined relation to cause the electrical condition of a reference point individual to said test device to assume 'a particular value and means responsive to the assumption by all of said reference points of predetermined particular values to give an indication that said characters have a predetermined relation. The circuit shown is used to detect a binary type code set up as positive and.negative voltages on terminals 6, 7, 8 by comparing it with the complementary code applied to the respective terminals 9, 10, 11, the complementary voltages being positive and negative. If positive voltage is applied to the terminals 6, 9 the point 18 assumes a positive voltage and current flows through rectifier 19 and resistance 25 to junction 27 and ground, and the grid of the valve 1 becomes markedly positive. The grid of the valve 2 is at substantially ground potential, and the conducting operation of the valve 1 makes the cathode of both valves positive so that the valve 2 cannot conduct. If negative voltage is applied to the terminals 6, 9 current flows through resistance 26 and rectifier 20 so that the voltage on the grid of the valve 2 becomes markedly negative and the valve is non-conducting. Similar considerations apply to terminals 7, 10 and 8, 11. The valve 2 can conduct, therefore, solely if the voltages at terminals 6 and 9, 7 and 10, 8 and 11 are complementary and if a code combination is applied to the terminals 6, 7 and 8, the valve 2 will remain non-conducting until the complementary code combination is applied to the terminals 9, 10 and 11. A predetermined incoming character may be detected by applying the complementary character to the terminals 6, 7, 8 and the incoming character to the terminals, 9, 10, 11. Specification 674,595 is referred to.

Abstract: 736,951. Threading shuttles in automatic looms. COEURTYS SOC. ANON. June 5, 1950 [June 7, 1949], No. 14027 /50. Class 142(2). The weft end of a newly inserted cop is threaded before the shuttle is picked by means connected to the cop changer mechanism and which exerts on the weft first a pull in the direction of the shuttle axis, then a forward pull, and finally a downward pull. The cops are held in a circular magazine and the ends are led over a guide 3 and secured to a pin 4. Simultaneously with the movement of a cop inserter 5, a rocker arm 10 moves downwards and its forked end engages the weft end, pressing it against two prongs 20a, 20b and pulling it down between them. At the end of the travel of the arm 10, a projection 10c engages one arm 17a of a spring biased lever and moves a second arm 17b of the lever away from an arm 14b. The arm 14b, urged anticlockwise by a spring 15 and connected to a hook 14, is thereby released and the hook 14 engages the weft and gives it a forward pull so that it enters an oblique threading slot in the shuttle. When the hook 14 pivots forwards, a hook 14a also pivots and retains the weft loop held by the rocker arm, which returns to its initial position. A hooked rod 22, actuated by levers 23, 27 from a cam 29 moves downwards and pulls the weft into an eye in the shuttle and into an eye on the slay. In an alternative construction, the exhausted shuttle passes into a box 42 positioned beyond the usual boxes 41. The weft end from a new cop is superimposed on a hook 47 pivoted on a pin 46 and mounted on a member 45 on the picker spindle. When the member 45 pushes the replenished shuttle back into one of the boxes 41, the hook 47 engages a cam plate 50 and pivots on the pin 46 drawing the weft forwards and into the path of a hooked rod 53. The rod 53 is reciprocated by a pinion 54 and by rack and pinion mechanism 57, 58 on the loom frame and draws the weft downwards. The rods 22, 53 also remove the cut weft ends. Specification 721,192 is referred to.
