Patent GB-575570-A (GB)
Title: Improvements in or relating to the twisting of artificial yarns
Filed: 1944-03-28
Abstract: A process for treating artificial fibre yarns, e.g. viscose, cuprammonium, cellulose acetate or polyvinyl yarns, particularly high twist yarns, to overcome snarling in knitting &c. operations, comprises applying to the yarn, prior to knitting, a hydrogenated fatty oil of melting point above 30 DEG  C. in the molten state or in solution, and thereafter twisting the yarn.  The weight of oil distributed in the fibre may be from 2-30 per cent of the dry untreated yarn.  The twist imparted to the yarn, which may be sufficient to cause kinking in the untreated yarn, may be set by means of heat.  Examples of the oils which, when hydrogenated, may be used are: beef or mutton tallow; lard; wool, bone or horse fat; castor; soyabean; palm; cod; pilchard.  The oil may be applied by immersing the yarn in a solution thereof, any of the usual solvents, e.g. Stoddards, xylene, &c. being used, following which it is centrifuged and then twisted up to say 60 turns per inch.  The twist is then preferably set, as by treatment in a steam cabinet.  In an example, 400 parts of hydrogenated tallow and 200 parts of xylene were melted together at 150 DEG  F. and 50 denier 36 filament cuprammonium rayon skeins were soaked therein for 20 mins.  After removal, they were centrifuged down to a take-up of 20 per cent and after storing for a week in air tight cans were thrown and twisted to 50 turns per inch.  The twisted yarn was then steamed at 140 DEG  F. wet bulb, 134 DEG  F. dry bulb for 15 minutes and was stated to have a good "hand" and to be free from snarling.

Title: Improvements in and relating to brush making machines
Inventor: COATES THOMAS WILLIAM
IPC: A46D3/04
Filed: 1959-02-23
Abstract: 868,010. Making brushes. EVANS & SON (PORTSMOUTH) Ltd., J. Feb. 11, 1960 [Feb. 23, 1959], No. 6167/59. Class 19. In a brush-making machine wherein tufts of bristles are inserted into rows of holes in a brush stock, the spread of bristles, already inserted in a hole, overthe next hole to be filled is prevented by a pair of guard members each of which is capable of being disposed in the path of the bristle-inserting tool whereby it is pivoted to deflect the inserted bristles away from the inserting tool. In Figs. 1, 4, the guard members 6, 7 are plates hinged to a support 5 which is slidable vertically in a fixed guide bracket 2 by a fluid pressure cylinder 11 and return spring 9, as shown, or by a double acting fluid pressure cylinder, or cam means or solenoid means. The brush stocks may be fed automatically and the machine may be arranged automatically to fill successive stocks, in which case, if the stock A is filled from the bottom row upwards, the stock B which replaces it must be filled from the top row downwards. The deflection of bristles must accordingly be downwards in the filling of stock A and upwards for stock B. In the former case, the support 5 is raised so that the plates 6, 7 which when inoperative are pulled together by the spring 8, are separated by the tool 12 striking the operative plate 7. In the latter case, the support is lowered so that the plate 6 becomes the operative plate. In a modification, Fig. 8, a single pivoted plate 6a serves as the deflectors, a coil spring on the pivot 6b tending to maintain the plate 6a in a vertical position. When the support 5 is fully raised, the tool 12 swings the plate clockwise to deflect the bristles upwardly, and when the support is lowered, the plate is swung counter-clockwise to-push the bristles downwardly.

Abstract: 1358221 Venting steam apparatus K FUJIWARA 10 Feb 1972 [10 Feb 1971 31 March 1971] 6350/72 Heading B8X [Also in Divisions F2 and F4] A steam tap of the thermally activated type adapted to provide an air vent and vacuum breaker in steam using equipment (not shown) to which the tap is connected comprises a floating disc valve 10 in a pressure chamber 9 in which valve an auxiliary valve member 11 is incorporated and a bi-metallic ring 19 is arranged to co-operate with a frusto-conical surface 18 on a fixed bushing 16 situated in an annular groove 7 formed between annular valve seats 5, 6 below the disc valve 10. The bushing has one or more through holes 17 and a cover member 8 engages over a valve seat portion 4 of the steam trap body 1 to form the pressure chamber 9 between an inlet port 2 and an outlet port 3. Thus, at temperatures below a predetermined value the bi-metallic ring is contracted and co-operates with the inclined surface 18 to exert an axial force whereby the valve disc is prevented from closing on the valve seats 5, 6 and at temperatures above this value, the ring is expanded to co-act with the inclined surface to remove the axial force and allow the valve disc to close. On start-up, with the ring contracted to hold the disc open, any air in the steam using equipment or piping connected to the trap is vented through the inlet port 2, an inlet passage 21, the gap between the valve disc 10 and valve seat 5, apertures 17 in the bushing 16 and through a discharge passage to the outlet port 3. Simultaneously the auxiliary valve 11 is urged upwardly to close against its valve seat 13 by the pressure acting through the port 2. The creation of vacuum conditions in the equipment will draw the auxiliary valve 11 downwardly to the open position to create vacuum conditions in the chamber 9 which will allow back pressure from the inlet port 3 to raise the valve disc 10 and break the vacuum. The bi-metallic ring may be positioned between the valve seat 6 and cover member 8 and the ring co-operates with an inclined surface formed on the under-surface of an annular member arranged above the ring. In a further embodiment the valve 11 may be replaced by a through hole by means of which the pressure communicates with the inlet port through the inlet passage 21 when the valve disc is in the closed position. In a further form, the hole is formed in the casing 8 to connect the pressure chamber directly with the inlet port via the passage 21 by a cap screwed directly to the pipework of the steam using equipment.

[Class 35.] An electrostatic machine comprising a moving element such as an endless belt 1 passing through a charge accumulating body 7 has a collector 23, removably or adjustably arranged within the body and electrically connected thereto and means are arranged within the body to charge the moving element from the collector oppositely to the body. The belt 1 of paper, varnished cambric, silk &c. is mounted on rollers 2, 3 and driven by an electric or other motor 6. The belt is separately excited adjacent the roller 2 by a collector 13 having a number of sharp points close to the belt surface and electrically connected field pieces 14, 15. A high voltage source, e.g. the secondary of a transformer T in series with a rectifier R, is connected across the collector and field pieces to charge the belt as it moves towards the body. A portion of the charge is taken by a collector 30 and the remainder is given up inside the body to the collector 23. The collector 30 is electrically connected to field pieces 26-29 within the body and the field pieces 26, 27 in conjunction with the collector 23 impart an opposite charge to that portion of the belt moving towards the roller 3 whereby the charge in the body is increased. The portion of the belt moving away from the roller 3 is charged by a self exciting arrangement comprising an earthed collector 31 and electrically connected field pieces 32, 33 and collector 34. The belt portion moving into the body from the roller 3 gives up its charge to a collector 25 which in conjunction with the internal field pieces 29, 30 imparts an opposite charge to the portion moving towards the roller 2. In order that the internal collectors and field pieces may be removable for adjustment or repair they are carried on insulating slides 46-48 held in an insulating support 42. The collectors 23 and 25 are held by set screws and rods 49, 50 whereby their positions can be adjusted. The field pieces are connected together by conducting plates 53 arranged in recesses in the sides of the insulating support 42 which are engaged by spring pressed contacts 54 at the ends of the field pieces. Removable closure plates with inwardly flared opening 8 and 9 for the passage of the belt and secured to the body by screws provide access to the slides. In order to prevent contact of the oppositely charged belt portions when a long belt loop is employed insulating rollers 11 may be provided. Specification 415,484 is referred to.
