Abstract: 583,073. Finishing and coating fabrics. INTERNATIONAL LATEX PROCESSES, Ltd. June 29, 1944, No. 12357. Convention date, July 3, 1943. [Classes 42 (i) and 140] A process for producing an ornamental fabric comprises adhering a network of flexible material 12, Fig. 2, to an extensible fabric 11 which is then stretched, say, in the direction of the arrow A. In this condition the flexible material is "set" leaving the threads of the fabric as seen from the side opposite the flexible material (Fig. 4) farther apart over the holes in the flexible network than where adhered to it. The fabric is preferably knitted, say of rayon or silk, and may not be fully stretched in the operation described so that the final product is still extensible. It may also be stretched in more than one direction. Depending on the amount of extensibility required in the final fabric the flexible material may be nitrocellulose, vinyl resin, or, preferably, rubber, in which case the "setting" process is vulcanising. A second layer of fabric may be provided on the opposite side of the flexible material layer. Specification 565,595 is referred to.

Patent GB-680670-A (GB)
Title: Surgical stocking
IPC: A61F13/08
Filed: 1950-05-18
Abstract: An elastic stocking is so formed as to provide a compression which decreases from the foot upwards so as to compensate for hydrostatic pressure in the veins.  This is done by cutting the fabric proportionally smaller towards the foot so that the degree of tension, when the stocking is worn, is correspondingly greater. The dimensions may be ascertained by measuring the circumference at vertically spaced points on the leg or by using a paper or fabric gauge, Fig. 9 (not shown), having a central strip from which a series of ribs project.  This is placed against the leg and the ribs are folded closely around it, their ends being overlapped and stuck together.  The ribs are then cut and the gauge removed, the resulting lengths of the ribs indicating the leg circumference at the corresponding points.

Filed: 1948-05-07
Abstract: 654,444. Two-stroke engines. BROWN. J. R. May 7, 1948, No. 12609 [Classes 7(ii) and 7(vi)] In two-stroke compression ignition engines, particularly miniature engines, in which crankcase compression is employed to feed an explosive mixture produced in a carburetter or similar device into the combustion chamber, the charge is introduced into the top of the combustion chamber through a port which is small compared with an exhaust port at the bottom of the chamber and opens with or later than the exhaust port as a function of the movement of the piston. The cylinder compression ratio may be varied by screw threads of different pitch provided between the cylinder head 7 and the cylinder barrel 4 and a contrapiston 10 respectively, so that when the head is rotated only slight axial movement of the contra-piston occurs. The charge enters an annular combustion chamber after crankcase compression through ports 3 in a restricted tubular piston tail, and the exhaust leaves by ports 5 which open later in the cycle. The ports 3 may be throttled by a plug extending down the tubular parts 11 of the contra-piston, which part may alternatively be used as an inlet for the combustible mixture supply. The annular combustion chamber may be formed between a semi-spherical roof and a rounded piston head.

Title: Process of impregnating fabrics and felts and the products so produced
IPC: D06M15/07
Filed: 1943-08-07
Abstract: Fabric or felt is impregnated in order to make it firmer or stiffer by disposing over it a temporary backing sheet bearing a film of organic thermoplastic material, applying heat and pressure to melt the film and cause the material thereof to penetrate the fabric or felt, and removing the backing sheet, the thickness of the film of thermoplastic material being limited so that the fabric is not filled, but remains porous.  The filaments, yarns, threads, &c. forming the fabric or felt are adhered together at their intersections.  The fabric may be woven, knitted, or netted. The temporary backing may be of regenerated cellulose, or smooth-surfaced calendered paper, and the thermoplastic film may be applied thereto by spreading or spraying a solution of the thermoplastic material in a solvent such as acetone or ethylene dichloride.  The thermoplastic material may be polyvinyl alcohol, a polymer of vinyl chloride, vinyl acetate, styrene, acrylic or methacrylic acid ester, a copolymer of vinyl chloride and vinyl acetate, a polyamide resin, a cellulose derivative, a mixture of a cellulose derivative and a synthetic resin, a synthetic rubber such as polymerized chloroprene, butadiene, or isobutylene, or a polysulphide synthetic rubber.  Thermosetting synthetic resins, such as phenol- or urea-formaldehyde or an alkyd resin, may be applied while in the thermoplastic condition and hardened by heating after transfer to the fabric or felt. Plasticisers may be added to the thermoplastic material or applied to the fabric before treatment, e.g. methyl phthallyl ethyl glycollate, dibutyl phthalate, triphenyl or tricresyl phosphate, dicyclohexyl phthalate, the methyl glycol ester of acetylricinoleic acid, and water-soluble plasticisers such as glycerine and glycols which may be removed from the finished fabric by washing.  The thermoplastic material may be coloured or modified before or after application to the fabric by means of dyes, pigments or fillers, e.g. titanium dioxide, kaolin, wood flour or diatomaceous earth.  The coated backing and the fabric or felt may be pressed together under pressures of 1000-10,000 lbs. per sq. in. at temperatures of 100-300 DEG  C. for 10-60 seconds.  The fabric, or the applied film, or both, may be preheated.  The Specification as open to inspection under Sect. 91 describes also the application to the fabric or felt of films that have been cast on a smooth surface, e.g. a stone or metal slab, a roller or belt, or a sheet of regenerated cellulose, gelatine, casein, waxed paper, or glassine paper, stripped from the smooth surface, and used immediately, or after storage.  This subject-matter does not appear in the Specification as accepted.

Filed: 1947-05-14
Abstract: 629,132. Dynamometers. TAYLOR, L. A. May 14, 1947, No. 12959. [Class 106 (ii)] [Also in Group XXIII] A torque measuring device in a dynamometer comprises an elongated torque member secured at its ends to coupling members, an indicator extending alongside the torque member and attached to one end thereof carrying a scale or datum line adjacent a corresponding datum line or scale carried at the other end of the torque member. As shown, the elongated torque member is a square-sectioned spring-steel rod 56 secured at its ends to coupling members 57, 58 adapted to be engaged in driving contact with a mechanism, the torque of which is to be measured. A cylindrical sleeve 63 surrounds the rod 56 and is welded at 64 to the member 58, its other end, which freely engages an annular recess 65 in the member 57, being reduced in diameter to form a shoulder 66. A freelyrotatable ring 67 is held against this shoulder by a spacing piece 68 and is provided with a lug 70 which is engaged by a similar lug 69 on the coupling member whereby relative twist between the sleeve and driving head is transmitted to the ring during the operation of the mechanism, moving a datum line 72 on the ring over a scale 71 on the sleeve. The ring 67 remains in the position of its maximum deflection and thus enables a reading of maximum torque to be taken when the mechanism is again stationary. The invention is also applied to torque-measuring spanners (see Group XXIII).
