Title: Improvements in or relating to the production of polymers of 4-vinylcyclohexene dioxide with cellulose esters
IPC: C08G59/24
Filed: 1948-05-28
Abstract: 4-Vinylcyclohexene dioxide is heated with a cellulose ester in the presence of a polymerization catalyst.  The product, a hard polymeric material, may be used as a coating composition and for films.  Any cellulose ester may be used, such as the nitrate, acetate, propionate, butyrate, acetopropionate and acetobutyrate. The proportion of cellulose ester used is limited by its compatibility with the dioxide and may be from 5-20 parts by weight or even more per 100 parts by weight of solution, and when high concentrations of ester are used it may be necessary to add such a solvent as acetone. The polymerization may be carried out at 85-90 DEG  C. or higher, depending on the catalyst employed. Plasticizers for cellulose esters may also be incorporated, provided they are compatible with the 4-vinylcyclohexene dioxide. Suitable plasticizers are dioctyl, diethyl, dibutyl and diamyl phthalates, tricresyl and tributyl phosphates and butyl stearate. In general, the polymerization is carried out by cooling a solution of the cellulose ester in 4-vinylcyclohexene dioxide (to which has been added a plasticizer if desired) to 0 DEG  C., adding a polymerization catalyst, and heating the mixture slowly to 85-90 DEG  C.  In typical examples (all parts by weight), (1) 5 parts of acetone-soluble cellulose acetate sheet is dissolved in 95 parts of 4-vinylcyclohexene dioxide to give a 5 per cent solution. 100 parts of this solution are cooled to 0 DEG  C. and 0.15 parts of perchloric acid as a 9 per cent solution in acetic acid added. The mixture is then slowly heated to 90 DEG  C. and maintained at this temperature, giving a hard colourless polymer after 24 hours; (6) to 100 parts of a 10 per cent solution of cellulose nitrate in 4-vinylcyclohexene dioxide are added 5 parts by weight of dioctyl phthalate and the solution cooled to 0 DEG  C. 0.15 Parts of perchloric acid are added as a 9 per cent solution in acetic acid and the mixture heated to 90 DEG  C.  Specifications 642,799, 642,800, 642,983, 648,456 and 651,797, [both in Group IV (b)], are referred to.

Title: A method of controlling a subsidiary clock and subsidiary clocks controlled thereby
IPC: G04C13/14
Filed: 1965-04-06
Abstract: 1,106,041. Clocks. LABORATORNI PRISTOJE, NARODNI PODNIK. April 6, 1965 [April 11, 1964 (2)], No. 14495/65. Heading G3T. A secondary clock having hour and minute hands is driven by its own power supply such as a constantly running synchronous electric motor (not shown) through an energy storage device or spring barrel 125-127 wound by the motor. The control is by an escapement comprising a pivoted armature 116 operated at one minute intervals by successive pulses of opposite polarity received from a master clock. The armature alternately moves out of the path of one arm of an escape lever which has two arms 114, 115 of unequal length, and moves into the path of the other arm. The minute hand 104 is connected to the escapement through a train 105, 106, 108, 110 from the barrel. The motor, through a pinion 129, drives a wheel 128. This wheel is automatically clutched to the barrel to re-wind the spring, as disclosed in Specification 1,090,187. Wheel 128 also drives a seconds hand 102 through a frictionally mounted wheel 130 which rotates an arm 134 so that at the twelve o'clock position this arm co-operates with a star release wheel 109 fast with wheel 108 of the other train. To allow for frequency variations affecting the motor speed, and to ensure that the seconds hand registers precisely with the twelve o'clock position at the time of the impulse from the master, this hand is normally driven slightly fast and is held momentarily at the twelve o'clock position by the star wheel 109 without the motor being arrested. The hour hand (not shown) is driven by suitable reduction from the minute train. In another embodiment, Figs.1 and 2 (not shown) the seconds hand and train are omitted. The escapement carries an air brake 112.

Title: Antifouling Covering
IPC: B32B27/00
Filed: 1967-03-30
Abstract: 1,185,902. Laminated antifouling covering. B. F. GOODRICH CO. 30 March, 1967 [31 March, 1966], No. 14512/67. Heading B5N. [Also in Division B7] A covering resistant to marine fouling organisms comprises a reservoir layer 12 of material containing a toxic agent for poisoning or repelling marine fouling organisms, and a toxic agent transfer control layer 14 of elastomeric material between the layer 12 and the surface of the covering which is exposed to the fouling organisms in use, the transfer control layer 14 being capable of regulating the transfer of the toxic agent from the reservoir layer 12 to the outer face of the layer 14 to provide thereon a desired minimum concentration of the toxic agent. Both the reservoir layer and the control layer may be elastomers selected from neoprene, isobutylene-isoprene copolymers, styrene-butadiene copolymers, cis-polybutadiene, ethylenepropylene copolymers, polyether- and polyesterurethanes, butadiene-acrylonitrile copolymers, natural rubbers, epichlorohydrin rubbers, and silicone rubbers. The elastomers are preferably vulcanizable or cross-linkable with sulphur, sulphur-containing compounds, metal oxides, peroxides, or amines. The reservoir layer may be cellular e.g. an open celled polyurethane or p.v.c. foam. The elastomers used are preferably solvents for the toxic agent which is preferably an organotin compound of the formula (R 3 Sn) n X where R is an alkyl or phenyl group, n is 1 or 2 and X is a sulphide, oxide, chloride, fluoride, bromide, chromate, sulphate, nitrate, laurate, hydroxide, acetate, octanoate, resinate, dimethyl dithiocarbamate, naphthenate, paravinyl benzoate, acrylate, methacrylate, hydride, isooctylmercaptoacetate, or methoxide radical. Preferred compounds are exemplified. Preferably the layer 14 has a low solubility limit and the layer 12 a high solubility limit for the toxic agent, and the layer 12 may be super-saturated therewith. The layers may be produced by adding the toxic agent as a dry powder or oil to the elastomer at the polymerization stage or to a solution of the elastomer. The elastomers may be extruded, rolled, or moulded to shape, or calendered on to fabrics. The layers 12, 14 may be vulcanized together or secured by adhesive, and then vulcanized. The layers may be further laminated to metal, wood, plastics, fabrics, concrete or fibreglass, and are preferably secured as sheets or strips to ship hulls, buoys, or pier piling. In other examples the control layer envelopes the reservoir layer, or pads of the reservoir layer material lie between and are spaced by sheets of the control layer material.

Title: Voltage regulating system for alternating current machines
IPC: H02P9/32
Filed: 1949-05-31
Abstract: 658,576. Automatic voltage control systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. May 31, 1949, No. 14556. Convention date, June 4, 1948. [Class 38 (iv)] In a system for automatically controlling the voltage of an alternator, the alternator excitation is derived or controlled from the alternator terminals through a circuit including a parallel combination of condenser and D.C. saturable reactor and through a rectifier, the condenser having a lower impedance than the reactor at normal voltage, and the saturating current of the reactor being dependent on alternator voltage. In Fig. 4 to stabilize the output voltage of a three-phase alternator 1 its field winding 2 is excited by the output of a bridge rectifier 3 supplied from the alternator terminals in series with the parallel combination of condenser 4 and the A.C. winding 5 of a saturable reactor. The saturable reactor has two opposed D.C. windings 6<SP>1</SP>, 6<SP>11</SP> excited by the outputs of bridge rectifiers 12<SP>1</SP>, 12<SP>11</SP>, supplied from the alternator terminals in series with a constant impedance 19 and a voltage dependent impedance 20 respectively. Variation of alternator voltage thus varies the differential effect of windings 61, 6<SP>11</SP> which, since the reactance of the saturable reactor is greater than the reactance of the condenser, influences the alternator field excitation in the appropriate sense to stabilize alternator voltage. In a modification a bridge having a pair of constant impedances and a pair of voltage dependent impedances, e.g. saturable reactors, in opposite arms, detects variation of alternator voltage and controls, through a rectifier, the excitation of a single D.C. winding of the saturable reactor. The alternator excitation may be controlled indirectly through an exciter machine. Specifications 571,851 and 641,977 are referred to,

Abstract: 1482897 Spinning yarns HOLLANDSE SIGNAALAPPARATEN BV 12 April 1976 [22 April 1975] 14938/76 Heading D1F In a method of making fine (e.g. 15 tex count) "twistless" yarn from a sliver or roving of staple fibres which is wetted and drafted in wet condition and the resultant thinner strand subsequently false-twisted and bonded, the wetting operation is effected with a liquid mixture, perhaps aqueous, containing a latent solvent for at least a portion of the staple fibre (only some of the fibres and/or only surface portions of the fibres); bonding is effected by activation of the solvent by raising the temperature to a value above that at which the liquid mixture (except for the solvent and components/additives it is desired to retain) is removed from the strand and below the melting point of the fibres to be (partially) dissolved; drying of the strand is effected under evaporation of the solvent. As described the fibre strand is brought into contact with the surface of a rotated heated drum whereon occur the successive steps of removing unmounted elements of the liquid mixture, activation of the solvent and evaporation thereof. Examples describe polyacrylonitrile fibre and polyacrylonitrile/ cotton fibre blend rovings treated with solvent on the bases of tetramethylene sulphone to which a wetting agent is added.
