Abstract: 643,376. Shuttles. LINEN INDUSTRY RESEARCH ASSOCIATION, BOFFEY, H., WEBB & CO., Ltd., and WEBB, W. H. Dec. 2, 1947, No. 31792. [Class 142(iii)] A shuttle for a loom for weaving has a longitudinal cavity for containing a coreless cop c lined with a pile fabric or other material having hairs or projections d on its surface which serve to prevent the cop from unravelling as the yarn is consumed. The tube D thus formed completely encloses the cop except for an aperture G<1> at one end through which the cop is inserted. This aperture can be closed by a lid K hooked over pins e and h, and a longitudinal slot G is preferably furnished in the top of the shuttle. The running end of the yarn is led over lambs wool or fur O, through an eye P and out of the shuttle through an eye Q. An alternative cover, fig. 2, (not shown), consists of a strip of metal hingedly mounted and controlled by a spring. Modified forms have hinged or detachable end pieces carrying the tip whereby the cop may be inserted directly into the tube at one end or the tip may be offset to allow insertion of the cop.

Title: Improvements in the manufacture and production of polymerisation products from polymerisable substances consisting of or comprising styrene and/or its homologues
IPC: C08F2/16
Filed: 1930-10-27
Abstract: Polymerization products derived from styrene or its homologues or mixtures thereof are made by polymerizing an aqueous emulsion of the said substance, if desired by means of a peroxide, treating the resulting emulsion with steam which may be saturated or slightly superheated or an inert gas such as carbon dioxide or nitrogen whilst warming if desired at any pressure below atmospheric and finally coagulating the product, for example by means of acids such as hydrochloric or acetic acids, strong cooling or anodic electro-deposition.  The polymerized product may be washed with water or suitable extracting agents such as methyl alcohol and worked up alone or with solvents, softening agents, gelatinizing agents, cellulose derivatives, artificial or natural resins, fillers, sulphur, dyestuffs, &c., into artificial masses, lacquers, films, artificial threads or pressed shaped articles. In examples, (1) styrene emulsified in water containing ammonium oleate is polymerized in the presence of hydrogen and benzoyl peroxides; the product is steam-distilled and coagulated by means of acid.  (2) Styrene containing ethyl benzene is emulsified in water containing ammonium oleate and abietate and when polymerized in the presence of hydrogen peroxide, the product is steam-distilled and coagulated by means of an acid to give a polymerization product soluble in benzene.  (3) Styrene and acrylic acid ethyl ester are emulsified in water containing stearic acid, benzoyl peroxide and ammonia; the polymerization product is steam-distilled and coagulated with acetic acid; the product is washed with water, dried in vacuo and freed from stearic acid by extraction with methanol.  (4) Styrene is emulsified in water in the presence of stearic acid, linoleic acid and ammonia, and the emulsion is polymerized; the emulsion is steam-blown and then coagulated by means of acetic acid. Specifications 307,936, [Class 2 (iii), Dyes &c.], and 355,573 are referred to.

Abstract: 137,287. Descarpentries, M. E. July 30, 1917, [Convention date]. Limbs, artificial.-The stump of a leg is fitted into a socket T attached to the body by two straps D. A projecting rim C in the socket bears on the top of the hollow leg portion B when the wearer is in the upright position. Bars F attached to the part B are jointed in the region of the knee and carries at their upper end a strap G for passing round the thigh. A light wooden block H projects from the bottom of the part B, and its front and rear faces form an obtuse angle slightly less than that formed by the corresponding faces of the foot I. A projection M on the foot engages a, correspondingly shaped hollow formed in the block H. A pin P passes through holes formed in the projection M, and in the side walls of the hollow N. Resilient means such as a spring Q tend to keep the rear faces of the block H and the foot I in contact. The Specification as open to inspection under Sect. 91 (3) (a) describes a construction in which the bars F were carried down to the ankle where they were jointed to an extension passing round underneath the foot, which in this case was not provided with a projection M. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1467454 Internal shoe drum brakes KOBER MANPAR AG 23 July 1974 [30 July 1973] 32550/74 Heading F2E An internal shoe drum brake for trailers having an over-running braking system comprises a part of floatingly mounted brake shoes 1, 2 operatively connected at one pair of adjacent ends by a spreading assembly 3 and at the other pair of ends by a transmission assembly 6. The assembly 6 is such that on braking with the trailer travelling in a forward direction both shoes are applied firmly to the brake drum but on the trailer travelling backwards the assembly moves to allow the shoes to move away from the drum thus eliminating the tendency of the overrunning mechanism to apply the brakes. The assembly comprises an adjustable strut 11 which engages the shorter arm in the form of a cam 10 of a bell-crank lever 9, the layer arm 17 carrying a roller which abuts an end of the brake shoe 2. The free end of the longer arm 17 of the lever 9 is as shown, bifurcated and extends around the end of the brake shoe. The roller 18 is urged into abutment with the brake shoe 2 by a torsion spring 19. The spring 19 may be anchored in the back plate or by a brake shoe pull-off strip 5. During braking with the trailer moving in the reverse direction the spreading assembly expands with the result that the shoe 2 abuts a stop 23, the brakes then being appliable by a hand actuated transmission which further expands the spreading assembly.
