Abstract: 746,118. Sausages, linking. CROSS, L. P. Feb. 9, 1954, No. 3759/54. Class 28(2). A filled sausage 15 is divided into links of connected sausage 17 by being engaged in the groove 71, Fig. 13, of a rotated plate 58 which forms necks in the sausage and passes the links through a rotating throat 75 which twists the necks, the links then passing to a rotating cylindrical container 19 on the inside of which the sausages collect by centrifugal force, the container 19 being moved slowly from the necking and twisting mechanism by a hydraulic cylinder and piston 110, 112. When the container 19 reaches its outer movement it actuates a switch (133, Fig. 2, not shown) to stop the hydraulic mechanism and the motor 107, Fig. 5 (not shown) and to apply a brake 109 (not shown) to the motor to stop rotation of the motor and container 19. The sausage length 15 passes between feed belts 23 on its way to the necking mechanism 16. A curved guide 41 leads the sausage length round through 180 degrees to the necking plate 58. An adjustable wall 42, Fig. 10 (not shown), permits adjustment of the tension on the sausage as it is picked up and drawn away by the grooves 71 in the plate 58. During the necking action the sausage transfers itself from groove 71 to a recess 72 in the diametrically opposite necking device. When the cylinder 19 stops rotating the coil of sausages drops on to one of a number of support bars 117, indexed round by hand to be inside the cylinder 19 as it moves outwardly. Fig. 1 shows a number of such bars 117 loaded with sausages from which they can be lifted off by a hand inserted stick 21 and carried to a smoking chamber.

Filed: 1931-02-10
Abstract: Filamentous yarns are treated with a solution from which a roughening substance is deposited on to the surface of the yarns, said roughening substance being capable of ready removal without modification of the material of the yarns.  The solution used may be a solution of the roughening substance itself, or the roughening substance may be precipitated from the solution by chemical means, the solution in either case being preferably of high concentration. According to a modification, the yarns are subjected to the vapour of a sublimable substance.  Examples of suitable solutions of roughening substances are solutions of ammonium or barium chloride; barium, potassium, or sodium nitrate; aluminium, ammonium, iron, magnesium, potassium, or sodium sulphate; zinc sulphate; sodium carbonate and the carbonates and bicarbonates of potassium and ammonium; sodium phosphate; sodium hydrogen phosphate; sodium borate; the alums, for example, potash alum; acetates, oxalates, tartrates, and many of the sodium salts of organic acids; barium, calcium, or lead acetate; potassium, or sodium oxalate; Rochelle salt; tartar emetic; naphthalene; benzoic, citric, phthalic, salicylic, and tartaric acids.  Aqueous or organic, for example alcoholic solutions may be used.  As an example of a substance which may be formed by chemical action, lead chloride is mentioned.  The roughening substances are readily removed by means of the solvents by which they were applied; lead chloride is removed by hot water.  The process may be applied to filamentous yarns of all kinds, for example, yarns of cellulose esters or ethers, reconstituted cellulose, such as viscose, nitrocellulose, and cuprammonium silk, or natural silk.  The yarns so treated have a reduced tendency to slip during knitting, weaving, and the like.  Specification 372,797 is referred to.

Abstract: 548,266. Pencil holders. BLAKE, W. H. (Fabrique Suisse de Crayons Caran d'Ache Soc. Anon). March 31, 1941, No. 4292. [Class 146 (iii)] A propelling pencil has slidable lead-feeding and lead-retaining jaws both of which project from the body of the holder. A pair of opposed feed-jaws 6, Figs. 3 and 6, having resilient limbs, are attached to a tube 4 slidable in the body 1 of the pencil, and are operated by a cap against the pressure of a spring 13. Between the feed-jaws are located retaining-jaws 5, the resilient limbs of which are integral with a tube 14 surrounding the tube 4 and frictionally engaging a boss 10 thereon. The tube 14 is also controlled by the spring 13, which bears against a flange 16 thereon. The feedjaws 6 tend to close on the lead, and the retaining- jaws 5 tend to move apart. When the cap is depressed, both pairs of jaws at first move outwards together, owing to the frictional engagement between the tubes 4, 14. The jaws 5 are then arrested by the engagement of a shoulder 18 on the tube 14 with the tapered part of the body 1. The jaws 6 continue to move outwards, carrying the lead with them to the position shown in Fig. 4. On the release of the cap, both pairs of jaws are retracted. The jaws 5 are arrested by engagement with the mouth of the holder, which forces them together, so that the lead is clamped. The jaws 6 then slide over the lead and return to intitial position, in which they also clamp the lead. A magazine tube 2 for leads is located between the tube 4 and the cap. It communicates with the tube 4 by means such as a conical hole, to ensure that the leads pass out one by one.
