Title: Improvements in a process for the production of halogenated hydrocarbons
IPC: C08F8/20
Filed: 1955-07-07
Abstract: Normally solid, semi-solid or tacky olefin polymers in which the unsaturation is predominantly of the trans-internal or terminal vinyl type and which are substantially insoluble in low-boiling chlorinated solvents at temperatures at which such solvents exist as liquids at atmospheric pressure may be halogenated, e.g. with elemental chlorine, bromine or iodine, either (a) in homogeneous solution in low-boiling chlorinated solvents, e.g. carbon tetrachloride, chloroform, methylene chloride and 1,1,1-trichlorethane, at superatmospheric pressure at temperatures above the normal boiling-point of the solvent, or (b) in the molten state.  Catalysts, e.g. benzoyl peroxide, diisopropylbenzene hydroperoxide, cumene hydroperoxide, dimethyl and diethyl alpha, alpha1-azodiisobutyrate, alpha, alpha1-azodiisobutyronitrile, alpha, alpha1-azobis-(alpha, gamma-dimethylvaleronitrile) and ultra-violet light may be present. Alternatively the temperature may be reduced and the pressure reduced to atmospheric when a partially halogenated polymer soluble in the chlorinated solvents has been obtained, and the product further halogenated.  The first stage may be conducted with the polymer in solution in tetrachlorethane, chlorobenzene or dichlorobenzene which may be substantially removed before further halogenation in solution in the low-boiling solvents.  Specified polymers are those of ethylene, propylene, 1-butene, 1-pentene, 1-hexene and copolymers thereof, e.g. of ethylene and propylene, which may be prepared by polymerization, e.g. in isooctane, in the presence of chromium oxidesilica and/or alumina catalysts as described in Specification 790,195.  Alternatively the polymers may be halogenated and, if desired, at least partially dehalogenated in substantially a single step to produce vulcanizable products by reacting the polymer in the molten state at temperatures of 150-300 DEG  C. with a halogenating agent, e.g. chlorine, bromine, iodine, carbon tetrachloride, carbon tetrabromide, carbon tetraiodide, hexachlorethane, chloroform, iodoform, bromoform or phosgene, optionally in the presence of a dehydrohalogenating catalyst, e.g. magnesium, zinc, magnesium chloride, zinc chloride, barium chloride or ultra-violet light.  The dehalogenation may be effected by raising the temperature when substantial halogenation has occurred, preferably while flushing the reactor with carbon dioxide or nitrogen to remove the hydrogen halide formed.  The products may be vulcanized by incorporationg conventional vulcanizing ingredients, e.g. sulphur, zinc oxide, magnesium oxide, stearic acid and N,N-dimethyl - S - tert - butylsulphenyl dithiocarbamate, and stabilizers, e.g. hydroquinone monobenzyl ether, and heating.  Pigments, e.g. carbon black, graphite, titanium dioxide, malachite and iron oxide, may be incorporated and the products moulded, extruded to form pipes, tubes and wire insulation, or used as coating materials or heat insulation.

Title: Improvements in and relating to resin compositions
IPC: C09D5/25
Filed: 1960-06-03
Abstract: A composition comprises 100 parts by weight of polyvinyl acetal, 20 to 200 parts by weight of an adduct of a polyisocyanate and an organic compound containing reactive hydrogen, i.e. a polyurethane, 1 to 30 parts by weight of a phenol-aldehyde resin and 0,5 to 20 parts by weight of a melamine resin.  The composition may be a solution in an anhydrous organic solvent. The polyvinyl acetal is obtained by reacting a polyvinyl alcohol or partially hydrolysed polyvinyl acetate with an aldehyde such as formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, or benzaldehyde.  The polyisocyanate may be phenylene, diphenylene, tolylene, naphthylene, diphenylmethane, cyclohexane, ethylene, tetramethylene, or hexamethylene diisocyanate, or a polyaryl polyisocyanate, a trimer of a polyisocyanate, or a reaction product of a diisocyanate or triisocyanate with polyhydric alcohols, or trimers and isomers thereof.  The reactive hydrogen compound may be a phenol, cresol, xylenol, secondary aromatic amine, a mono or polyhydric alcohol, amide lactam, mercaptan or enol.  The preferred polyurethanes are those obtained by reacting a monohydric phenol with the reaction product of an arylene diisocyanate and a polyhydric alcohol such as ethylene glycol, propylene glycol, glycerol, trimethylol propane, pentaarythritol, or hexanetriol.  The malemine resin may be obtained by reacting a melamine with an aldehyde, optionally in the presence of an alcohol, or by aftertreating a melamine-aldehyde-alcohol-reaction product with an aryl sulphonamide. The phenol-aldehyde resin may be any of the conventional types.  The preferred composition of the phenol aldehyde resin is that obtained by reacting one mol. of meta-para-cresol or para-tertiary butyl phenol with 0,1 to 2,0 mols. of formaldehyde.  The compositions may be used for electrical insulation, e.g. for coating wires.  The compositions are "cured" by heat-treatment at about 150 DEG C.  The solvent for the composition may be trichloroethylene, ethylene dichloride, a hydrocarbon, or a mixed solvent comprising an alcohol, ester, and a hydrocarbon.

Title: Improvements in and relating to the measurement of registration errors
Inventor: ADAMSON ROBERT GEORGE
IPC: B41F13/02
Filed: 1968-04-26
Abstract: 1,216,924. Selective signalling. HURLETRON Inc. 26 April, 1968, No. 19883/68. Heading G4H. In a system for measuring errors in registration between a travelling web and a machine operating thereon, scanner 14 senses reference marks on the web, a presettable counter 68, 70 counts pulses from encoder 50 produced in synchronism with movement of a part of the machine and produces an output at 78 simultaneously with a scanner pulse when the registration is correct, and a counter 108 counts encoder pulses between the occurrence of the scanner pulse and output 78, regardless of which occurs first, to indicate errors in registration. Zero reference generator 52 provides a pulse at a fixed point in a cycle of machine operation to start feeding encoder pulses to counter 68, 70 and to set bi-stables 86, 88. When counter 68, 70 reaches a count of 100, it is reset to a number determined by the setting of switches 44, 46 and corresponding to the desired degree of offset between the reference marks on the web and the zero reference of the machine. The first occurring output from 78 or scanner 14 resets the corresponding bistable 86, 88 and an output is obtained from gate 96 until the second of the two pulses occurs. Bi-stable 98 assumes a condition depending on which pulse occurs first and controls the polarity of the output from a digital to analogue converter 114. The output of converter 114 is fed to a zero centred meter 48, though it could be used for automatic correction of the web registration.
