Title: Improvements in flame-retarding compositions
IPC: C08K13/02
Filed: 1955-05-09
Abstract: A flame-retarding composition consisting of a dispersion in water of polyvinyl chloride, polyvinylidene chloride, a vinyl chloride-vinylidene chloride copolymer or a mixture of these polymers, antimony trioxide and a plasticizer, is prepared by dispersing the antimony trioxide in the plasticizer, emulsifying the resultant dispersion in water with the aid of an emulsifying agent and mixing the resultant emulsion with a latex of the polymer.  The plasticizer may be a mixture of a conventional plasticizer and a chlorine-containing plasticizer as described in Specification 791,802.  The emulsifying agent may be dioctyl sodium sulphosuccinate, part of which may be dissolved in the plasticizer prior to dispersion therein of the antimony trioxide.  In a preferred process, the pH of the water employed for producing the emulsion may be decreased by adding acid, e.g. acetic acid, and raised after admixture of the emulsion with the latex by addition of alkali, e.g. ammonia.

Title: Engraving of printing forms
IPC: B41C1/05
Filed: 1977-03-09
Abstract: The printing forme (41) is clamped in a device (43), and is not moved during the actual processing by a laser beam (50) directed onto it. Arranged in an axially displaceable manner next to the printing forme (41) is a focusing head (42) which deflects and focuses the laser beam onto the surface of the printing forme. A beam deflecting system (53) deflects the laser beam as a function of the pattern to be scribed, e.g. perpendicular to the direction of displacement of the focusing head (42). In the case of pulsed operation of the laser, the laser beam is concentrated onto a point of the surface of the printing forme for a number of pulses which corresponds to the desired cup volume of the pattern. This procedure optimizes the use of the energy in the laser beam and increases the scribing power by a multiple with respect to known methods. <IMAGE>

Title: Polymerization catalyst compositions and process for their preparation and for polymerizing unsaturated monomers
IPC: C08F4/12
Filed: 1961-03-20
Abstract: A polymerization catalyst comprises a metal salt coated on the surface with a very thin layer, which may be from 1 to 1,000 molecules thick, of a salt of a different metal.  The supporting metal may have an atomic weight from 24 to 209 and be from Group II, III, VII or VIII, in particular cobalt, magnesium or cerium and may be in the form of a sulphide, silicide, phosphide or preferably halide; its crystals may have a size between 1 and 300 mesh (ASTM). The coating metal salt may be a sulphate, nitrate, sulphide, chlorate, or preferably halide of a metal from Group III, IV, V or VIII having an atomic volume of less than 20, in particular a halide of titanium, vanadium or zirconium.  The coating layer is advantageously 10-100 molecules thick or 0,1 - 5 mg. per 1g. of metal salt carrier.  The catalyst may be made by a vacuum-plating technique in which a solution of the coating metal salt (e.g. TiCl4 in heptane) is deposited upon the supporting metal salt (e.g. CoCl2) crystals with the subsequent removal of the sovlent.  Examples are given in which propylene, ethylene or styrene are polymerized (see also Group IV(a)).ALSO:A process for polymerizing unsaturated monomers comprises contacting the monomer in the absence of molecular oxygen and water with a catalyst composition comprising a metal salt coated on the surface with a molecularly thin layer of a salt of a different metal (see Group III).  The supporting salt may be a halide, sulphide, silicide or phosphide of cobalt, magnesium or cerium.  The salt coating may be a halide, sulphate, sulphide, nitrate or chlorate of titanium, vanadium or zirconium.  Metal alkyls such as diethyl aluminium chloride and aluminium triethyl may be used as co-catalysts.  Many monomers are specified among which are ethylene, propylene, octadecene, butadiene, methyl acrylate, vinyl chloride, vinylidene bromide, acrylonitrile, vinyl acetate, divinyl succinate, diallyl phthalate, vinyl crotonate, diallyl ether, vinyl butyl ketone.

Abstract: <PICT:0985024/C6-C7/1> <PICT:0985024/C6-C7/2> <PICT:0985024/C6-C7/3> Metal such as Al, e.g. for electrolytic capacitors or printing plates, is electrolytically etched to increase its surface area by a fluctuating unidirectional current produced by a repeated sequence comprising charging a capacitor from a D.C. source and then temporarily short circuiting the capacitor across an etching bath. Fig. 1 shows Al foil being etched in a bath 7, washed in a bath 20, e.g. of distilled water, and dried by lamps 21.  Charging and discharging of a capacitor 4 is controlled by switches 2 and 5 or, in a modification, by switches 15 and 5.  The switching sequence at 2 and 5 is controlled at 23.  Fig. 2 shows the voltage Vc of capacitor 4 and etching current Ie during operation.  From t1 to t2 switches 2 and 5 are closed, from t3 to t4 both switches are open, and from t4 to t5 switch 2 is closed and 5 open. The etching bath contains 2% NaCl solution at 74  DEG C. and is stirred by air or gas from a fan 6.  Fig. 3 shows a further embodiment wherein individual electrodes 38 are etched while connected to a current rail 35.  The time interval t1 t2 may be lengthened so that after the current has fallen to the value of the rectifier current, the rectifier current flows for a short while as a steady D.C. before it is switcher off. Capacitor discharge etching may be followed by D.C. etching at 5-20 Amps./dm.2.  After etching, dielectric oxide may be formed on the metal in a forming bath at a voltage not exceeding 100 volts, e.g. 17 or 64 volts.

Filed: 1956-04-06
Abstract: <PICT:0806092/III/1> <PICT:0806092/III/2> <PICT:0806092/III/3> <PICT:0806092/III/4> In a system controlling the ratio of air t hydrocarbon supplied to a reactor for the production of lamp black wherein a liquid hydrocarbon passes axially into the reaction zone and air is injected in a direction tangential to the side wall thereof, control is effected in response to the analysis of the effluent gas from the reactor.  A flow of oil from tank 10, Fig. 1, maintained constant by flow controllers 17, is injected by jets 45, Fig. 2, axially into reactors 13, air being injected through a tube 46 surrounding the nozzle to prevent oxidation of the nozzle and the deposition of carbon thereon.  A considerably larger flow of air is injected through passages 47, Fig. 3, and directs the combustion products in a helical path along the reactor forming a blanket of flame along the reactor wall which decomposes the rest of the oil to lamp black.  The products are quenched by water injected through nozzles 49 and the lamp black is collected from successive filters 49, 54, 55 by a screw conveyer feeding a pulverizer 53.  The carbon black may be treated for shipment in a pellet mill.  The reactor outputs are sequentially tested in an analyser 34 valves 63, 70, 72 being opened in turn by solenoids 129, 133, 139, Fig. 4, in response to the closing of cam-operated contacts 120-122.  The cams are driven by a constant speed motor 111 and contacts 79-77 are simultaneously closed to connect the electrical output of the analyser 34 to the appropriate air flow controller 33.  Air inlet valve 32 of the reactor being tested is thereby adjusted.  The analysis in unit 34 determines the methane, or acetylene content of the effluent gases in an arrangement where the effect of infra-red radiation on temperature sensitive resistors 95, 98 is controlled in accordance with the proportion of methane or acetylene in a sample cell having transparent windows 93.  Transparent filter cells 94, 97, contain respectively methane or acetylene, and air and the bridge comprising resistors 95, 98 and potentiometer 102 is balanced initially with the sample cells empty.  Unbalance caused by the infra-red absorption in the sample cells results in current from a source 100 driving through a reversible servomotor 103 in sliders on potentiometers 102, 106, the former tending to restore the bridge balance and the latter to apply a correcting potential from a source 107 to the appropriate control unit 33.  In an alternative arrangement wherein an air and oil mixture is injected tangentially into an enlarged combustion chamber into which oil is fed axially, the rate of flow, and proportion of the mixture is maintained constant and the axial flow of oil is controlled in accordance with the effluent gas analysis.  A mass spectrometer may be used to determine the concentration of hydrogen.  Specifications 621,031 and 679,818 are referred to.
