Title: A process for the production of a water-resisting finish on fibrous materials
IPC: D06M13/402
Filed: 1934-03-21
Abstract: Fibrous materials such as artificial silk are rendered water-resisting by impregnation with the reaction products of high molecular quaternary ammonium bases or salts on high molecular acid alkyl esters of polybasic strong inorganic acids or their alkali salts.  The impregnation may be effected with a mixture of the separately prepared solutions or the two solutions may be applied separately in either sequence.  The quaternary ammonium salts have a minimum molecular weight of about 120 and may be those of the aliphatic, aromatic, aliphatic-aromatic, hydroaromatic or heterocyclic series, such as those derived from acylated derivatives of ethylene diamine, and prepared, for example, by treating the diamines with alkyl sulphates such as di-amyl sulphate or with chlorinated, brominated or iodated paraffins, naphthenes or petroleum or tar fractions.  The high molecular acid alkyl esters contain at least 8 carbons atoms in the molecule and comprise dodecyl, hexadecyl, octadecyl, and octadecenyl sulphuric acid esters, ceryl sulphuric acid esters and the corresponding derivatives of ricinoleic alcohol, linoleic alcohol, secondary and tertiary aliphatic alcohols, aromatic, hydroaromatic, and heterocyclic alcohols.  Alkyl phosphates or their alkali salts may also be used.  In examples: (1) artificial silk is treated with an aqueous solution containing octadecylpyridinium chloride, hexadecyl sulphuric acid ester and octadecyl sulphuric acid ester; (2) viscose artificial silk is treated firt with an aqueous solution of octadecylpyridinium chloride and then with an aqueous solution of the sodium salt of octadecyl sulphuric acid ester; (3) viscose artificial silk is impregnated first with an aqueous solution of hexadecylpyridinium bromide and then with an aqueous solution of the sodium salt of tetradecyl sulphuric acid ester.

Abstract: 293,373. Comley, C. W. A. April 4, 1927. Money - delivering apparatus. - In order to facilitate the giving of change in tramcars, omnibuses, or at ticket windows of railway stations, etc., hand operated coin delivery tubes are assembled in banks. Fig. 1 shows tubes 13 - - 19 assembled in a satchel 10 formed with pockets 11, 12 for silver and bronze coins respectively. The tubes 13 - - 16, are adapted to deliver two, three, four and five pence respectively, at a time, the tubes 17, 18, 19 delivering a sixpence, a shilling and a florin respectively. The lower part of the front wall of the satchel may be formed to open independently of the upper part. The tubular coin tubes, shown in detail in Figs. 2 and 3, are formed with a flanged piece 21 at the top. A plunger 24 is urged by a spring 25 towards the flanges 21 to hold coins 25 so that the uppermost coins lie opposite a lateral outlet 27. An open ended slot diametrically opposite the outlet 27 permits a finger to be placed behind the coins to eject them. In order to prevent accidental ejectment, spring-pressed plates 36 may normally close the outlet 27, pressure behind a coin moving the plates 36 outwards. In order to replenish a coin tube, a pin 30 is actuated in a slot 31 in the tube to move the plunger 24 downward against the spring action. The flanged piece 21, normally locked in position by a lug and catch, is swung on hinges into inoperative position, and an L-shaped tool 60, Fig. 7, having splayed, spring- connected arms 61, 62 is loaded with coins and inserted in the tube.

Abstract: 879,140. Yarns and threads. UNITED STATES RUBBER CO. March 19, 1959 [June 4, 1958], No. 9530/59. Drawings to Specification. Class 120(3) Composite yarn comprises a low-twist i.e. less than five turns per inch, multifilament, continuous filament thread e.g. of cellulose acetate, a polyamide or polyester, silk or viscose rayon, and a twisted or untwisted elastomeric thread e.g. of rubber, synthetic rubber or polyurethane, capable of at least 100% elongation and contraction therefrom. The threads are plied or intertwisted e.g. by a "Belgian Doubling" process, Fig. 1 (not shown) during which the elastomeric thread is elongated, as a result of which the individual filaments of the multifilament thread are "blossomed out" from their normal close parallel arrangement at a contracted condition of the elastomeric thread. The ratio of X to Y (indicating the excess of multifilaments over elastomeric thread) is at least 1À7 where X is the length in inches of the multifilament thread per unit length of yarn divided by the number of turns of ply twist in such unit length and where R is the radius in inches of the elastomeric thread relaxed, h is the length in inches of relaxed elastomeric thread in said unit length divided by the number of ply twists therein, and A is the ratio of the relaxed length in inches of the segment of elastomeric thread in said unit length to the segment's new length in inches at the stretched condition of the yarn at which Y is a minimum. When the elastomeric thread is of rubber and capable of elongating to and contracting from five times its relaxed length, the ratio X to Y is at least 1À4 where Y=#(2 #R)<SP>2</SP>+h<SP>2</SP>, X, R and h having the same meanings as above, and, in the contracted condition of the rubber thread component, the multifilament thread is wrapped therearound. The wraps may be loose and/or of random dimension and/or larger in diameter than the elastomeric core and may form entanglements, loops, kinks and/or curls. Embodiments of the composite yarn include an elastomeric core with a double cover. Specifications 370,761, 380,368, 757,478 and 847,673 are referred to.
