Title: Improvements in or relating to the production of vinyl chloride polymer and plastisols therefrom
IPC: C08F14/06
Filed: 1952-07-22
Abstract: Vinyl chloride polymers suitable for use in the production of plastisols are made by emulsifying liquid vinyl chloride alone or admixed with a minor amount of another mono-olefinic monomer and containing a dissolved peroxide polymerization catalyst with an aqueous solution containing between 0.1 and 5 per cent. of an emulsifying agent, homogenizing the emulsion by subjecting it to violent shearing action, heating with agitation at a temperature between 30 DEG  and 60 DEG  C. to effect polymerization, then heat-treating the aqueous suspension of polymer at a temperature between 90 DEG  and 160 DEG  C. for a period in excess of 10 seconds but less than that required to agglomerate and coagulate the polymer particles and recovering the polymer.  Unpolymerized monomer may be removed from the suspension before heat-treatment.  The homogenizing may be effected in a colloid mill or by forcing the emulsion through an aperture, e.g. of not more than 0.03 inch diameter, at such a rate that there is a pressure drop of more than 100 lbs. per sq. inch across the aperture.  Specified monomers are vinyl bromide, vinyl formate, vinyl benzoate, vinylidene chloride, methyl acrylate acrylonitrile, methyl methacrylate and styrene.  The emulsifier may be sodium or potassium myristate, laurate, palmitate, oleate, stearate, rosinate and/or hydroabietate, sodium or potassium lauryl sulphate, cetyl sulphate, oleyl sulphonate, alkylbenzene sulphonate and/or stearyl sulphonate, Turkey red oil or sulphonated mineral oils, sorbitan monolaurate, monostearate, or mono-oleate, polyethylene glycol esters, the sodium salt of dioctyl sulphosuccinate, cetyl dimethyl benzyl ammonium chloride or lauroyl pyridinium chloride.  Catalysts mentioned are lauroyl, caprylyl, stearoyl, benzoyl, acetylbenzoyl, p-chlorobenzoyl and 2, 4-dichlorobenzoyl peroxides, and t-butyl perbenzoate. Plasticizers mentioned for use in plastisols are di-(2-ethylhexyl) phthalate, dibutyl phthalate, dioctyl phthalate, diethyl sebacate and tricresyl phosphate.

Abstract: 146,434. Bound-Brook Oil-less Bearing Co., (formerly Graphite Lubricating Co.); (Assignees of Smalley, G. O.). June 8, 1918, [Convention date]. Channels in cylindrical bearings.-A self-lubricating bearing has a series of intersecting helical grooves containing graphite. Fig. 1 shows a core used in casting a tubular or split bearing.

Abstract: 183,703. Stone & Co., Ltd., J., and Darker, A. H. July 13, 1921. Dynamos, driving; indicators, application of.- For indicating the state of adjustment or output of pivotally suspended dynamos, particularly beltdriven generators of railway and other vehicles, an indicator arm is mounted on the dynamo so that it can be brought to an horizontal position by a correct adjustment of the dynamo. The generator d is suspended in the usual manner from the vehicle a and has an indicator arm h visible from the side of the track secured to it by a pivot bolt j and spring washers. A sheet metal pointer l mounted on the dynamo lies opposite a scale n on the indicator arm h. In use, the belt is tensioned by means of the screw-gear p until the correct output is obtained, whereupon the arm h is set horizontal by hand either directly or by means of the screw arrangement o. The index figure on the scale n opposite the pointer l is then chalked upon the vehicle. During the life of that belt, the screw-gear p may be adjusted to suit different conditions but the setting of the indicator arm is not altered. When a new belt is fitted, the screw gear is adjusted until the arm h is again horizontal. The setting of the arm h relative to the pointer n is not altered unless a radical change occurs in the service conditions, for example, if a greater output is required. In the case of a variable-speed dynamo in which the voltage or output remains practically constant above a certain speed, the indicator arm is fixed on the dynamo so as to be non-adjustable.

Predetermined lengths of material are measured by a pulse generator driven by the belt. After a pre-set count, a relay is operated to switch on a ramp generator producing an output voltage whose slope is proportional to belt speed, as measured by a tachogenerator.
