Title: A composition comprising asphalt and a copolymer of ethylene and vinyl acetate
Inventor: MILLS IVOR WILLIAM
IPC: C08L95/00
Filed: 1964-09-25
Abstract: Asphalt is obtained from a solvent-deasphalting petroleum refining process.  In a countercurrent treating tower in which asphaltic residuum flows downwards and liquid propane flows upwards, the top tower temperature is 130-200 DEG  F. at 200-500 p.s.i., 2.5-15.0 volumes of propane are used per volume of residuum.  Rheometric values of the asphalt are given.ALSO:A composition comprises asphalt and 1-50% based on the asphalt of a solid ethylene/vinyl acetate copolymer resin, and includes sand, fullers earth, and asphalt roofing scraps.  The asphalt may be natural, or derived from petroleum refining operations, e.g. vacuum distillation, solvent extraction and/or oxidation. The asphalt may have R and B softening point 150-350 DEG  F., pen (77 DEG  F.) 0-5 (50 g., 5 sec.), and ductility 0-3 cm., and may contain 10-40 vol per cent asphaltenes and 20-50% resins, the remainder being oil.  The copolymer contains 5-15 moles ethylene per mole vinyl acetate.  The asphalt roofing scraps are composed of felt, asphalt or tar and mineral aggregate. The composition may be made by heating the asphalt to 200-500 DEG  F., and slowly adding the resin with stirring.  The other ingredients may then be blended into the hot mix.  The process may be performed continuously. Fillers and extenders include clays, mineral aggregates, cement, asbestos, vermiculite and/or glass fibres.  1-10 parts by weight of filler may be used per part asphalt/resin.  The composition may be moulded into blocks, slabs and rods.

Title: Process for the preparation of hydrogen cyanide
IPC: C01C3/02
Filed: 1966-09-02
Abstract: HCN is produced by the reaction of a gaseous mixture of NH3 and a hydrocarbon, containing at least 2 carbon atoms per mole NH3, in the absence of a metal-containing catalyst, and in the presence of at least 0.05 moles CS2 (per mole NH3), which may be added as such, or formed in situ by reaction of the hydrocarbon with sulphur or a sulphur compound, e.g. H2S.  The hydrocarbon may be methane, ethane, ethylene, or benzene, or may be natural gas or "residual" coke oven gas (75% b.v. CH4, with N2, H2 and CO), which may contain some of the required sulphur.  A reaction temperature of at least 1000 DEG  C. may be maintained, e.g. by indirect transfer through the reactor walls, or by preheating the gases to 500-800 DEG  C.  The reactor may be packed or empty, and may be a chamber of a coke oven battery.  The CS2 is stated to react with H2 to form an activated C atom which reacts rapidly with NH3 to form HCN. In the examples, CS2/NH3 mole ratios of 0.5-3.3 and CH4/NH3 mole ratios of 2.0-5.1 are used.

Title: Improvements in or relating to a stop motion mechanism for yarn winding machines
IPC: B65H63/028
Filed: 1966-09-06
Abstract: 1,129,355. Stop-motion. ELITEX ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI. 6 Sept., 1966 [8 Sept., 1965], No. 39715/66. Headings DID and D1J. In a winding unit which has a clearer, a yarn-brake and a stop-motion acting on failure of the yarn to stop the unit and initiate operations in preparation for the resumption of winding, in case the stop motion does not operate because the feeler is not released when a yarn fails, an auxiliary stop motion is provided beyond the first in the direction in which the yarn travels and which acts to link a constantly-oscillating member and the first stop-motion to cause the feeler to swing to the released position. The unit comprises a supply bobbin 2 and a drum-wind take-up 21, the yarn between the two travelling over a brake 4 and a clearer 5. Below the brake is a main yarn-feeler 3 pivoted at 7 and urged by a spring 9 to swing between plates 10, but normally restrained from so doing by the yarn. The rear of the feeler is bent inwardly and upwardly to bring a part 11 adjacent the path of a constantly-rocking lever 12. Above the clearer is a pivoted auxiliary-feeler 6 spring-urged to move out from between plates 17, but prevented from so doing by the yarn. When the yarn breaks but is held in the clearer and continues to restrain the feeler (3), the feeler 6 is not so restrained and pivots to interpose its rear end 18 between the parts 11 and 12. When the lever 12 moves along an inclined side of the end 18, the part 11 is moved to cause the feeler 3 to swing to a position where it operates the stop motion and initiates the operations preparatory to the resumption of winding. Suction-ducts 19, 20 serve to take up dirt and broken ends of yarn &c.

Filed: 1962-10-22
Abstract: An aqueous solution of an olefinic compound which has an olefinic bond in the alpha,beta position to a carbonyl group or to a nitrile group, which contains as solubilizing agent for the said compound, a water-soluble quaternary ammonium alkylsulphate is subjected to hydrodimerization by electrolytic procedures, e.g. those described in Specification 967,956.  In an example a catholyte was prepared by dissolving acrylonitrile in an aqueous methyltributylammonium methosulphate solution and employed in a cell using aqueous methyltriethylammonium p-toluenesulphonate solution as anolyte.  The initial pH of the catholyte was adjusted to neutrality by addition of aqueous benzyltrimethylammonium hydroxide solution and acetic acid added during electrolysis to ensure that only slight alkalinity developed.  The electrolysis was conducted at 3 amperes for about 3 hours at cathodic voltages of -1.87 to 1.89.ALSO:An aqueous solution of an olefinic compound which has an olefinic bond in the alpha, beta position to a carbonyl group or to a nitrile group contains as solubilizing agent for the said compound a water-soluble quaternary ammonium alkylsulphate.  The quaternary ammonium cation may have aliphatic and/or aromatic organic radicals attached to the nitrogen atom and/or the nitrogen atom may form part of a heterocyclic ring.

[Also in Divisions B6 and G2]  In electrographic printing and/or display apparatus a latent magnetic or electrostatic image is applied to a print band or image carrier having an open weave structure, the selective charging being such that the powder is attracted to and substantially fills the apertures charged. The print band has square, rectangular or triangular apertures 5 and wires 3, 4 of circular, rectangular or square cross-section. The wires are of a magnetic material such as stainless steel when the print band is selectively magnetized and of an insulating or dielectric material when selectively charged electrostatically. The magnetic wire structure may have a supporting band of an insulating and non-magnetic material which is transparent to visible radiation, and further provided with a transparent interlayer of a non-magnetic and conductive material such as aluminium to obviate electrostatic attraction of magnetic powder. The print band can be incorporated in simple display apparatus (Fig. 1), or display apparatus including a duplicating printing stage where the image is transferred to a paper web by contact between the band and the web (Fig. 5). In (Fig. 4), the image is first transferred by contact from the print band to a heated transparent synthetic plastics web (12) which is then bonded to a paper web (16), sandwiching the image between the paper web and the plastics web.
