Title: Improvements in or relating to the vulcanization or prevulcanization of rubber or the like, and to the production of rubber or like derivatives
IPC: C08K5/18
Filed: 1946-10-16
Abstract: A vulcanizate, a prevulcanizate or a vulcanizable derivative is obtained by heating natural rubber or a synthetic rubber with an aromatic phenol or amine having one position ortho or para to the hydroxyl or amine group substituted by the grouping <FORM:0625845/V/1> (in which R and R1 are hydrogen or alkyl, and r is an organic or inorganic acid radical or hydroxyl) if a vulcanizable derivative is required, or having at least two such positions so substituted to produce a vulcanizate or prevulcanizate.  The aromatic compounds may be derived from benzene, or from naphthene, anthracene, phenanthrene, diphenyl or the di- or triphenyl alkyl series and may be substituted with a halogen such as bromine or sulphonic, nitric, cyanic, thiocyanic or cyanide groups, by organic acid radicals, hydroxyl radicals, or primary, secondary or tertiary amino groups. Specified compounds are bis(bromomethyl)-2,6, methyl-4, phenol; bis (bromomethyl)-2,6, methyl-4, aniline; bis(methyl 3, hydroxymethyl 5 hydroxy 6 phenyl methyl) 2,6 methyl 4 phenol; tertiary butyl 2, bis (hydroxymethyl) 4,6, phenol, bis(hydroxymethyl)-2,6 trichloro 3,4,5, phenol; and bis(form-oxy-methyl)-2,6 methyl-4 phenol.  Bases such as magnesium oxide, pyridine, aniline and quinoline may be added to react with the acids formed during the reaction.  The term natural rubber includes gutta percha and baleta but not reclaimed rubber.  In examples, 100 parts of rubber are mixed with 10 - 40 parts of one of the specified aromatic compounds and then heated for 30 - 120 minutes at a temperature of 125 - 155 DEG  C.

Title: Improvements in systems for the automatic control of winders and like installations
IPC: H02P25/26
Filed: 1931-11-09
Abstract: 392,155. Winding- apparatus. SMITH, G. D., Clevedon, Brooklands Road, Baguley, Cheshire, and ASSOCIATED ELECTRICAL . INDUSTRIES, Ltd., Crown House, Aldwych, London. Nov. 9, 1931, Nos. 31053/31 and 22035/32. [Classes 78 (ii) and 78 (v).] Electric plant.-In a system for the automatic control of winding &c. installations wherein the cage &c. operates on a predetermined speed cycle which, moreover, may be a reversing one, the main speed control means is actuated differentially on the one hand in accordance with the speed of the cage &c. and on the other hand in accordance with the speed of a pilot motor whose speed is dependent upon the actual position of the cage in its travel at least during portions of the travel. The winding drum 1 is driven by the induction motor 2, and is geared to a cam wheel 18 which has cams 19, 20 and an intermediate circular portion 21 corresponding respectively to the acceleration period, retardation period, and period of constant speed. The cam wheel actuates a push rod 15 which is connected to the slider 14 of the field rheostat 13 of a pilot motor 12. This motor drives the element 11 of differential gear mechanism 9. The element 10 of this mechanism is driven by the drum 1, and the casing element 8 drives a rotary master controller 7 shown in developed plan. This controller effects the energization of switchactuating coils 37 .. 42 which close the shortcircuiting switches 37 .. 42 of the rheostat 6 in the rotor circuit of the motor 2, and thereby vary its speed. Resistances 27 are inserted in the rotor circuit by the means described in Specification 343,316, [Group XXXVII], to prevent excessive voltage rise when the motor 2 is being braked by a primary phase reversal by the switch 4 or 5. Manual control of the motor 12 is provided by a lever 52. At the end of the wind the cage trips the switch 45 or 46 and causes the supply to the motor 2 to be cut off and the mechanical brakes to be applied. If the drum of the controller 7 has not stopped in the off position, the motor 12 is energized appropriately and rotates the drum to this position. In an overload or overwind emergency the brake solenoid 32 is de-energized and the main motor switch 4 or 5 tripped so that the rotation of the drum 1 is stopped, and cannot be restarted by operation of the pushbutton 43, it being necessary for the cage to be brought to the landing level by manual control of the motor. If at any point in the wind excessive overspeed occurs with a load too great for the reverse current braking to be effective, but without causing the tripping of the switch 4 or 5, the contacts 33 of an overspeed device, such as a centrifugal governor or Lilly controller, are opened, and the mechanical brakes applied..The motor 2 may be replaced by a steam or water turbine, synchronous motor, or other constant speed machine, or by a steam engine or internal-combustion engine.

Title: Manufacrure of cellulose ester film material
IPC: G03C1/795
Filed: 1972-07-06
Abstract: 1381762 Cellulose ester films EASTMAN KODAK CO 6 July 1972 [6 July 1971] 31698/72 Heading B5B A film is made by (a) casting a cellulose ester dope in the form of a wet film on to a web, the dope consisting of a solvent fraction and a dissolved fraction, the dissolved fraction consisting essentially of at least one film-forming cellulose lower fatty acid ester (i.e. where the lower fatty acid portion contains 2-4 carbon atoms) and the solvent fraction consisting essentially of at least one volatile solvent for the dissolved fraction and an effective amount of at least one soluble compatible organic monomer havng a molecular weight not exceeding 300 and being capable of free radical polymerization; (b) subjecting the wet film to a sufficient amount of ionizing radiation to cause the free radical polymerization of the compatible organic monomer or monomers, and evaporating a portion of the solvent fraction from the wet film thereby to cause the dope to set into the form of a partially dried film; and (c) thereafter stripping the partially dried film from the web and passing the partially dried film through a drying zone thereby to remove at least half of the organic solvent material remaining in the partially dried film. In examples, dopes are used containing equal proportions of cellulose acetate and as the monomer either styrene, vinyl acetate or 1,3-butylene dimethacrylate. The amount of monomer may be from 20 to 80 weight per cent of the solvent fraction, the dope being clear at the time it is cast on to the web. Conventional casting solvents are used. Irradiation is effected with a conventional high energy electron accelerator. Other cellulose esters and monomers are specified; and other ionizing radiations include positive ions, e.g. alpha particles, beta particles, gamma rays, X-rays and ionizing radiation from decomposing radioactive materials, e.g. radio-active cobalt. Preferably the amount of ionizing radiation is from 0À5 to 5 Megarads, and the ionizing radiation has sufficient strength to penetrate the wet film. Suitably the amount of the monomer or monomers is at least 5 weight per cent of the solvent fraction. The polymeric products obtained appear to be copolymeric, rather than blends. The method of the invention accelerates setting and so enables the film to be removed from the web for drying while it still contains a relatively high proportion of solvent. A preferred film contains at least 50 weight per cent of at least one lower fatty acid ester of cellulose and at least 10 weight per cent of at least one polymerized compatible organic monomer.
