Title: Process for dispersing ammonium bromide in resins
IPC: C08J3/22
Filed: 1960-06-23
Abstract: 890,426. Flame proofed polymers. DOW CHEMICAL CO. June 23, 1960 [July 1, 1959(2)], No. 22037/60. Class 2(6) [Also in Group V] A process for flame-proofing thermoplastic polymers of olefins or of alkenyl aromatic monomers comprises forming a concentrate of ammonium bromide having a particle diameter of not over 50 microns in a polyolefin having a molecular weight of from 1,500 to 10,000, or in an alkenyl aromatic polymer having a solution viscosity of from 0À5 to 6À0 centipoises, or in an emulsion latex of a polymer of an alkenyl aromatic monomer which latex is then spray dried, and then incorporating the concentrate into a compatible polyolefin or polymer of an alkenyl aromatic monomer in an amount sufficient to provide 15% ammonium bromide in the product. The compatible polymer may be the same as that in the concentrate or may be of higher molecular weight. The various polymers may be derived from ethylene, styrene, alpha-methyl styrene, o, m, or p-methyl styrene, nuclear halo-substituted styrenes and methyl styrenes, ethyl styrene, vinyl xylene, and mixtures with each other or with minor amounts of divinyl benzene, methylmethacrylate or acrylonitrile. The invention is applicable to the production of film or solid mouldings or cellular articles and Example II illustrates the production of a foamed, flame-proofed polystyrene. Optional ingredients disclosed are corrosion inhibitors such as diethylamine salt of octylphenyl esters of phosphoric acid and N-alkyl-amino butyric acid, Stoddard solvent, solubilizers such as polyoxyethylene sorbitan monolaurate, stabilizers, titanium dioxide, dibutyl tin oxide, dicumyl peroxide and calcium salt of tall oil acids.

Title: Improvements in automatic clutches
IPC: F16D43/14
Filed: 1946-07-25
Abstract: 625,120. Friction clutches. KIRKPATRICK, H. G. July 25, 1946, No. 22200. Convention date, Aug. 25, 1945. [Class 80 (ii)] In a centrifugal friction main or tail clutch for motor vehicles of the kind having weighted driving shoes sliding radially outward to contact a driven drum and in which cam means delay the movement of the shoes in both directions to increase engaging and decrease disengaging speed, compression springs are interposed between the actual friction members and the weighted portions of the shoes. As shown, sleeves 21, Fig. 1, slidable on the arms 12 of a driving spider 11 carry friction segments 19 co-acting with a driven drum 5 and have weighted portions 22 with a limited radial movement relative to the sleeves. Compression springs 32 normally hold the members 19, 22 spaced apart. Annular side plates 13, Fig. 2, held together on the spider 11 by springs 33, carry cam members 18 co-acting with balls 25 held apart in axial bores in the members 22 by spacers 24. Clutch engagement commences only when the balls, by pressing apart the plates 13, ride up the cams 18, and is completed by the sudden complete compression of the springs 32 when the balls pass the crest of the cams. Clutch disengagement is similarly prevented until the balls are thrust inwards past the cam crests, and is then sudden and positive. The pins 12 are lubricated through passages 42, 43 in the driving shaft 10 communicating with passages 41 in the spider 11. In Figs. 3 and 4 (not shown) the side plates 13 are replaced by flexible diaphragms rigidly bolted to the spider 11, and in Figs. 5 and 6 (not shown) the side plates 13 are fixedly screwed to the spider and the spacer 24 is replaced by a compression spring urging the balls 25 apart.

[Also in Division C7] An organic sulphoxide is produced by the anodic oxidation of the corresponding organic sulphide in a liquid medium comprising an organic solvent containing water and an electrolyte, wherein the solvent used dissolves a sufficient quantity of the electrolyte and gives a dielectric constant sufficient to produce the necessary ionic dissociation of the electrolyte, the solvent and the anion of the electrolyte having an oxidation potential which is higher than that of the sulphide, and the liquid medium is electrolysed between insoluble electrodes, the potential of the anode being maintained at a value exceeding the oxidation potential of the sulphide but below those of the solvent, anion of the electrolyte and of the sulphoxide to be produced. The electrolysis is preferably performed in a cell having one or more Pt or C anodes and one or more stainless steel or Pt cathodes, not separated by diaphragms or a cell having Pt or C anodes and C cathodes with at least one diaphragm. The anode potential is usually +0À4 to 1À7 volts and the organic solvent is suitably a dialkyl formamide, an aliphatic nitrile and/or a nitroalkane or, advantageously, the same organic sulphoxide as that which is to be prepared. The electrolyte may be an acid, e.g. sulphuric, nitric, perchloric, benzenesulphonic or toluenesulphonic acid or a salt, e.g. a halide, halogenate, perhalogenate, sulphate, nitrate or sulphonate of an alkali or alkaline earth metal. Amongst the examples, dimethyl sulphoxide is prepared by electrolysing (1) dimethyl sulphide, water, sodium p-toluenesulphonate and dimethyl formamide or (2) dimethyl sulphide, water, sulphuric acid and dimethyl sulphoxide.

Abstract: 278,871. Canadian-American Machinery Co., Ltd., and Dawson, J. C. Sept. 23, 1926. Folding paper.-In a paper-folding machine, such as a buckling folder or a knife folder, in which a pair of feeding or folding rollers are liable to be forced abnormally apart due to the thickness of work passing them, the gear connections between the rollers are adapted so as to remain in mesh even when the rollers are unduly separated. Fig. 1 shows a buckling folder having the usual rollers 1 - - 3 and buckling plate 4. The roller 1 drives the roller 2 through gears 12, 13, and the roller 2 normally drives the roller 3 through gears 14, 15, the roller 3 being resiliently mounted as usual and its distance from the roller 2 limited by collars 8, 9. To adapt the machine for dealing with heavy stock, the shafts of the rollers 2, 3 are extended, and auxiliary gears 16, 17 having a larger pitch circle than the gears 14, 15 are mounted on the extended ends 18, 19 and are formed integrally with collars 20, 21 giving a clearance between the rollers 2, 3 corresponding to the size of the gears. Similar collars 22, 23 are mounted on the other extended ends. In alternative arrangements, the auxiliary gears may be formed with abnormally deep teeth so as to maintain the driving connection and the collars 20 - - 23 dispensed with, or the use of auxiliary gears may be rendered unnecessary by making the gears 14, 15 with abnormally deep teeth. Driving connections between the rollers 1 - - 3 as described may be provided at both ends.
