Title: Improvements in or relating to package-supports for yarn or like packages and methods of making such supports
IPC: D06B23/04
Filed: 1936-07-16
Abstract: 477,054. Cutting and punching machines. FRANKLIN RAYON CORPORATION. July 16, 1936, No. 19789. Convention date, April 1. [Classes 31 (i) and 31 (ii)] [Also in Group IX] A hollow package support 2 for a yarn or like package is formed of superposed laminations of paper with holes 3 in its walls to assist fluid treatment of the package and has its outer periphery countersunk around each hole 4, Fig. 1, the material of the support being compressed there to a density greater than that of the remainder. of the support, and the outermost lamination being continued along the surface of the countersunk portions to present a smoothly curved unbroken surface to the package. The formation of sharp edges which might damage the yarn is thus avoided and fluids are prevented from permeating the material of the support at the holes. The ends of the support may be similarly compressed. The holes are formed and countersunk in a single operation. They may be formed by punches 5, Fig. 6, with filleted shoulders 15. A number of punches are preferably arranged in a line on a drop press, and a plurality of tubes may be perforated in one operation by employing a long continuous tube which is subsequently cut into a number of package supports. The tube is wound on to a mandrel 6 formed with countersunk holes 7 aligned with the punches 5. After formation of each row of holes, the mandrel 6 is rotated for formation of the next row. Cutting of the tube to form package supports may be effected by a rotary knife 20 shaped to compress the ends of the supports during the cutting operation. The terminal portion of the long tube may be trimmed by a similar knife or rounded off by a rolling tool 25. The supports may be coated or impregnated with a moisture proof and chemical resistant material. Specification 462,849 is referred to.

Title: Production of alkyl pyridines
Inventor: YEOMANS BERTRAM
IPC: C07D213/127
Filed: 1960-06-07
Abstract: Alkyl pyridines are produced by heating at 200-600 DEG C. in the vapour phase a methyl pyridine with an aliphatic aldehyde and an alkanol, the aldehyde and the alkanol each having from 1 to 4 carbon atoms in the molecule.  The methyl pyridine may contain one or more additional alkyl substituents.  Preferably the process is carried out in the presence of a condensation catalyst, e.g. silica, alumina, or a mixture of these, and the catalyst may contain a minor proportion of a modifier or promoter.  The water formed in the reaction may be removed by entrainment with benzene. In the example formaldehyde, methanol and a -picoline are heated in the presence of alumina to give mainly 2-ethylpyridine with a small amount of 2-vinylpyridine.

Title: Improvements in the manufacture of yarns, fabrics, and similar materials having a basis of cellulose acetate
IPC: D01F2/28
Filed: 1934-09-11
Abstract: Cellulose acetate filaments, yarns, and other textile materials are acetylated with a liquid medium comprising acetic anhydride dissolved in a diluent with the aid of ferric chloride, or a mixture of ferric chloride and hydrochloric acid, as catalyst until products of reduced solubility in acetone are obtained or until the products are insoluble in acetone.  The diluent may be benzene, carbon tetrachloride, xylene, hydronaphthalenes, kerosene, butyl or amyl ether.  The safe-ironing temperature, resistance to water, and resistance to delustring, of the textile materials are increased. The dyeing properties are altered, the affinity for dispersed insoluble dyestuffs being reduced.  A fabric containing yarns of ordinary cellulose acetate and similar yarns which have been acetylated may be differentially dyed by immersion in an S.R.A. blue dyestuff.  The catalyst may be applied with the acetic anhydride or previously and it may be applied as a solution and dried on the material.  The acetylation may be effected at reduced or increased pressure.  Yarns may be treated in hanks, or on perforated bobbins, or in the form of woven or knitted fabrics.  The yarns may be subjected to stretching, shrinking, or dyeing prior to the acetylation.  In examples, cellulose acetate yarn is treated with a mixture of benzene, acetic anhydride, and ferric chloride with or without hydrochloric acid.  The yarn is washed with benzene, water, and dilute alkali. It is practically insoluble in acetone. Specifications 389,823, 438,584, 438,585, 438,586, 438,587, 438,655, and 438,656 are referred to.

Abstract: 1,146,304. Treating textiles. CHEMISCHE WERKE HULS A.G. 6 May, 1966 [7 May, 1965], No. 20029/66. Heading D1P. The bond strength of cord filaments, e.g. nylon or viscose rayon, to an unsaturated elastomeric copolymer of ethylene or propylene with one or more α-olefines and one or more polyenes or to a rubber mixture containing such a copolymer is improved by impregnating the cord filaments with a mixture contaning (a) an aqueous dispersion of a copolymer of ethylene or propylene, one or more α-olefines and one or more polyenes having 2.5-20 carbon-carbon double bonds per 1000 carbon atoms, (b) an aqueous dispersion of a homopolymer or vinylpyridine or a substituted vinyl pyridine and (c) an aqueous solution of a rescrcinol formaldehyde resin, the weight ratio of copolymer to polyvinylpyridine being 99.9:0.1 to 60:40, drying them, contacting them with the copolymer or rubber mixture and vulcanising. Monomers used to prepare the copolymers include α-butylene, α-pentene, hexadiene-1,5, hexadiene-1,4, dicyclopentadiene, cyclooctadiene, methylcyclooctadiene, 1,4,9- decatriene and 1,2,4-trivinylcyclohexane. The mixtures used for the treatment may be produced by mixing solutions of the copolymer and polyvinylpyridine in benzene, dispersing the resulting solution in water containing an emulsifier, e.g. an alkylarylsulphonate, alkylsulphonate, alkyl sulphate or condensation product of a phenol or alcohol with ethylene oxide, distilling off the benzene, optionally heating at 50‹-100‹C for several hours and concentrating the mixture to the desired solids content, or by preparing dispersions of the copolymer and polyvinylpyridine separately and then mixing them and optionally heating for several hours at 50‹-100‹C. The solution of the rescorcinol-formaldehyde resin is added to these mixtures. The rubber mixtures may also contain fillers, e.g. carbon black, plasticisers, e.g. mineral oils, metal oxides, e.g. zinc oxide, organic acids, e.g. stearic acid, vulcanising agents, e.g. sulphur and vulcanisation accelerators, e.g. tetra methyl thiuram monosulphide.

IPC: G01R15/14
Filed: 1965-05-14
Abstract: 1,081,575. Transistor oscillator circuits: ENGLISH ELECTRIC CO. Ltd. May 13, 1966 [May 14, 1965], No. 20475/65. Heading H3T. [Also in Division H2] In a pulse generator circuit, e.g. for use in the protective system of Specification 1,081,576, and producing pulses having a repetition rate proportional to an instantaneous value of an A.C. signal, a capacitor 4 is charged through a rectifier 3 from a current transformer 1 until at an upper voltage limit a Zener diode 8 conducts to render a transistor 5 conducting. This renders a complementary transistor 7 conducting so that the capacitor 4 discharges through this transistor, an impedance network Z and a load 9 which may emit light pulses. When the discharge current falls to a predetermined low value, the transistors are turned off allowing the capacitor to recharge. In a further arrangement two of these pulse generator circuits are connected to the current transformer through oppositelypoled half-wave rectifiers so that one circuit produces pulses on the positive half-waves of the A.C. signal and the other produces pulses on the negative half-waves of the A.C. signal, Fig. 2 (not shown). The impedance network Z includes resistors, diodes and an inductor or capacitor, and assists in turning on and turning off the transistors, Figs. 3, 4 (not shown). In Fig. 5 (not shown) a defined turn-off network is added to this network and comprises further complementary transistors controlled by a further Zener diode. This arrangement also provides compensation for ambient temperature variations and ensures linearity.
