Title: A gauge device primarily for tracking and checking the angular disposition of road vehicle wheels
Filed: 1937-11-01
Abstract: 504,756. Gauging alignment of vehicle wheels. GRINYER. E. S. Nov. 1, 1937, No. 29848. [Class 106 (ii)] Comprises a particular construction of portable gauge device for checking the angular disposition of road vehicle wheels to secure proper alignment. A rigid structure is formed by telescoping arms 3, 4 adjustably secured by a screw 5 and arms 6, 7 extending at right-angles therefrom. The structure is supported by legs 8, 9 extending from the arms 6, 7. From the free ends of the arms 6, 7 extend centre pins 11, 12 which lie parallel to the beam 3, 4 and define a datum line passing through the wheel centres. The centre pins each carry rotatable sleeves 14, 15 which receive collars 16, 17. The latter are bored with holes large enough to allow the collars to turn about pins 18, 19 by which they are attached to the sleeves. The collars can turn about the axis of the pins which can move with their sleeves about the axis of the centre pins 11, 12. Extending diametrically of the collars are gauge arms 20, 21 on which are adjustably mounted feelers 22. The sleeves carry scales 23, 24, over which move needles or pointers 25, 26. The latter extend between plates spaced to enclose the needles the ends only of which are visible. The needles extend a little beyond their pivots 27 and are connected by short links 29, 30 to the gauge arms. The indicators have a central zero at which the needles stand when the wheels 13 are at right angles to the datum line. For checking purposes, the gauge arms must lie horizontal and vertical and spirit levels may be provided for this or flats upon which they may be placed. One or both centre pins may be threaded and pass through a threaded housing to give a fine adjustment. In use, after the centres are applied to the stub axle, the gauge bars are moved into the upright position and " toe in " measured. They are then placed horizontal and another reading taken. These may also extend rigidly from the beam or one or both arms a telescopic arm having a gauge pin which contacts the centre hole at the end of the rear axle when the device is in position for checking the front axle. The arm may be calibrated and the distance between front and rear axle checked.

Abstract: 1,205,152. Coated flexible sheet material. KURASHIKI RAYON K.K. 24 June, 1968 [22 June, 1967; 27 June, 1967; 18 July, 1967], No. 29920,68. Heading B2E. A sheet material with good surface hardness, moisture permeability and pliability comprises a flexible and moisture permeable fibrous base material and in adherent contact therewith a moisture-permeable embossed polymer layer having a thickness of 0.02- 0.09 mm and a specific gravity of 0.6-0.9. The polymer layer is produced by applying a layer of polymer solution in such a thickness so as to form a layer having a thickness of 0.02-0.09 mm after drying, treating said layer of polymer with a non-solvent for the polymer to coagulate the layer of polymer solution to such a degree that its coagulation is almost completed but some fluidity still remains, embossing the resulting polymer layer having remaining fluidity, and then solidifying the layer. The polymer layer is solidified either by coagulating the layer completely by treating it with a non-solvent for the polymer, followed by drying or by directly drying the layer. The fibrous base material may be impregnated with water or other liquid before the layer of polymer solution is applied. The fibrous base material specified is a polyurethane web of fibres produced from a melt of a mixture of nylon-6 and polystyrene. The polymer layer coating is preferably a polyurethane elastomer which may be blended with polyvinyl chloride, polyvinyl acetate or an ethylene-vinyl acetate copolymer.

Title: Purification of vinyl chloride
IPC: C07C17/38
Filed: 1964-08-04
Abstract: Vinyl chloride containing HCl as an impurity is purified by distilling said vinyl chloride in the presence of a compound containing at least one vic-epoxy group.  Preferred epoxy compounds are those of the formula <FORM:1070749/C2/1> where R is hydrogen or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, aralkyl or alkaryl radical and R1 is hydrogen or an alkyl radical. It is advantageous to use a 1-20 molar excess of epoxide based on the amount of HCl in the vinyl chloride.  If styrene oxide is used as the epoxy compound, it is preferred to effect the distillation in the presence of pyridine or an alkyl pyridine as this prevents the isomerization of styrene to phenylacetaldehyde.  In the preferred mode of operation, the impure vinyl chloride is fed to the bottom of a fractionation column and the epoxide, or a solution thereof, is introduced at a point at least several trays above the point at which the vinyl chloride is fed; the purified vinyl chloride is obtained as the overhead product. Examples are provided.
