Title: Improved Method for Compressing and Supplying Gaseous Media.
Inventor: IRMINGER RUDOLF
IPC: F02B33/44
Filed: 1917-11-09
Abstract: 111,663. Irminger, R. Nov. 13, 1916, [Convention date]. Compound piston pumps.-A charge of air for combustion in or the scavenging of an internal combustion engine or for other purposes or a charge of gas is supercompreesed in a chamber by subjecting it to the pressure in the cylinder of the engine by a premature opening of the exhaust valve. A single-cylinder engine is provided with a U-shaped pipe 22 which connects the chests of the admission and exhaust valve 17, 18. Air is forced into this pipe when the valves are closed, through a pipe 23. Towards the end of the working stroke the exhaust valve 18 opens and the air which is subsequently admitted to the cylinder is compressed. A valve 20 leads to the exhaust pipe 24, and allows the burnt gases to be expelled from the pipe 22 by the incoming air charge, if it is held open by the lever 29. The engine works on the ordinary fourstroke-cycle. Multi-cylinder engines are provided with exhaust and air chambers common to all the cylinders and situated respectively between the admission and exhaust valve chests and the U-shaped tubes.

Abstract: 1,068,388. Elastic yarns. BEAR BRAND HOSIERY CO. April 23, 1964 [Feb. 13, 1964], No. 16976/64. Headings DID and D1W. In a process of forming a composite elastic core yarn from an elastomeric - for example spandex - yarn 11 and from one or more rovings 49, by feeding yarn 11 to the front drafting rolls 42, 43 of a spinning frame, the yarn 11 is passed around a wheel 25 to which is applied a constant magnetic drag thereby to impart a constant elongation to the yarn as it reaches rolls 42, 43. Wheel 25, of nylon and having a hysteresis ring, is rotatably mounted on a bolt. Cylindrical magnets, adjustably spaced on the bolt from the ring, cause a braking force on the wheel, the magnitude of which is independent of the speed of revolution of the wheel. Adjacent the drafting rolls, yarn 11 is guided by a wire finger 26 rigidly secured to bar 30 which is slowly traversed and which also supports trumpet guides for the rovings. The yarn path from bobbin 12 to rolls 42, 43 is preferably at least 30" long. Yarn 11 is twisted when unwound from bobbin 12 and backtwisted when wound on bobbin 59. To reduce the liveliness of the composite yarn it is subjected to a vacuum, steam is introduced therein, and then the vacuum is restored to remove excess moisture from the yarn. The rovings may be composed of wool, cotton, nylon, polyacrylonitrile, polyester, -or rayon fibres, and blends thereof.

Title: Unsaturated sulfonamides of chlorosulfonated olefin polymers
IPC: C08K3/06
Filed: 1957-05-29
Abstract: A sulphur-curable polymer of a terminally unsaturated olefin in which some of the hydrogen atoms have been substituted by chlorine and some by the grouping -SO2NR1R2 in which R1 is hydrogen, or an alkyl radical of from 1 to 18 carbon atoms, R2 is an alkenyl radical of 3 to 8 carbon atoms, and R1 and R2 contain not more than 22 carbon atoms, and in which the molecular weight of the olefin polymer is greater than 10,000 and the nitrogen content is from 0,2 to 1,5% by weight of the product, and the product is only unsaturated by reason of the alkylene radical R2, is made by reacting a normally solid chloro-sulphonated polyolefin of a molecular weight greater than 10,000 with an amine of the formula -NHR1, R2 where R1 and R2 have th same meanings as set out above.  The treatment with the amine is preferably effected in an inert solvent and an excess of amine generally used.  The polyolefin is preferably made by polymerizing the monomer in the presence of a compound of Group IV(a), V(a), or VI(a) of the Periodic Table in the presence of a compound such as a finely divided metal or an organometallic compound.  The chlorosulphonation of the olefinic polymer is preferably effected in the presence of an inert solvent e.g. carbon tetrachloride, by treatment with chlorine and sulphur dioxide.  The chlorosulphonated polymer may be stabilized with epoxy compounds such as a condensation product of epichlorohydrin with diphenols. The reaction between the amine and the -SO2 Cl groups of the chlorosulphonated olefin polymer is preferably effected in an inert solvent.  The amine may be N-ethyl-allyl, methallyl, butenyl, pentenyl or octenyl amine.  The polymers may be made by polymerizing ethylene, propylene, butene-1, or hexene alone, or in admixture.  The treatment of a chlorosulphonated ethylenepropylene copolymer with N-ethyl allylamine is exemplified.  The amine treated chlorosulphonated polymer may be vulcanized by normal rubber techniques e.g. sulphur and a vulcanization accelerator and small amounts of zinc or magnesium oxide.  Specification 591,058 is referred to.

Abstract: 630,007. Phase changing. BRITISH THOMSON-HOUSTON CO., Ltd. July 5, 1945, No. 17134. Convention date, July 12, 1944. [Class 38 (ii)] [Also in Group XXXVII] In a single-phase to three-phase conversion system, the single-phase input and two phases of the three-phase output have common terminals 1, 2 and a saturable reactor 7 in parallel with capacitor 6 is connected between the third output terminal 3 and terminal 1. The system may supply a three-phase motor 8 through a switch 9, the effect of the saturable reactor 7 and condenser 6 being that the voltage drop between terminals 1, 3 falls as the load rises, and during starting the three-phase side remains balanced. The choke may act as an autotransformer to supply the condenser at a voltage higher than that between terminals 1, 3. Fig. 1 illustrates the fundamental principles of single three-phase converters of the kind to which the invention relates, but without the saturable reactor. Terminal 5 of condenser 6 may be moved along an auto-transformer 4 connected between terminals 1 and 2 to keep the load balanced at different power factors.
Patent GB-353616-A (GB)
IPC: C09F1/00
Filed: 1930-06-04
Abstract: Esters of natural or artificial resin acids are prepared by heating to high temperatures the resin acids with such esters of other acids which have a boiling point of more than 200 DEG  C., and the acid of which after having been set free may easily be eliminated by physical or chemical methods, during or after the reaction.  This elimination may be by distillation under ordinary pressure or in vacuo, by washing, by treating with alkaline solutions or by decomposition (e.g. decomposition of oxalic acid by heating into carbon dioxide, carbon monoxide and water) or by oxidation (e.g. oxidation of formic acid to carbon dioxide and water).  In resin acids are included all natural and synthetic resinous products which still contain acid components and which are capable of reacting with alcohols to form esters, particularly colophony, Congo copal, Manila copal, kauri copal, the acid synthetic resins obtained by condensation of natural resins with phenol aldehyde condensation products, (e.g. glyptal resins, urea resins and resins produced from aliphatic dicarboxylic acids such as sebacic acid, with alcohols) and finally the purely synthetic acid resins containing at least one free carboxylic group, e.g. the condensation products of salicylic acid with formaldehyde. Esters which undergo a condensation when heated are not suitable for the reaction.  Examples are given of the esterification of a French colophony with dibutyl phthalate to give butyl abietate, of Congo copal with benzyl acetate to give Congo copal benzyl ester, of Congo copal with tristearine to give Congo copal glycerine ester, of kauri copal with benzyl acetate to give kauri copal benzyl ester and of Manila copal with dibutyl phthalate to give Manila copal butyl ester.

Abstract: 596,304. Moulding tyre beads. WELLINGS, J. H. Sept. 9, 1944, No. 17244. [Class 87 (ii)] The bead of a tyre is repaired by applying unvulcanized repair material to it, placing it in a full circle mould having flanges a for moulding the faces of the bead and vulcanizing the repair material whilst in the mould. The flanges do not extend beyond the bead of the tyre so that the sides of the tyre are not subjected to any distorting forces and tyres having different shapes of side wall may be repaired in the same mould. The flanges a are mounted on flanged discs e which can be clamped together by the bolts f to compress the beads between the flanges and an inner two-part spacer or member g. The material is vulcanized either by steam heating, for which pipes d are provided, by electrical hot plates or by steam chambers, the inner mould member g being made from a heat conducting material if it is desired to vulcanize the inside of the bead. Alternatively, pressure may be applied by an inflatable air bag inside the tyre or by compression of the mould members between the plates of a curing press. In a modification (not shown) which uses such an air bag the clamped discs e are dispensed with, the mould members a being held together by flanges on inter-fitting telescopic tubes which are secured together by fastening members of the bayonet-joint type.
