Abstract: 137,947. Fish, J. R. March 5, 1919. Circulating or passing liquids through matcrials; piling fabrics in rope form. - Relates to plaiting-down apparatus for bleaching-kiers and the like, and consists of apparatus capable of swinging in the kier and about its vertical axis, and having its plaiting-arm and rotating drawrollers capable of reciprocating radially within the kier to plait down the fabric in rope form, and capable of saturating the fabrics by means of liquors from a hollow bonnet and arm fed by valved connexion through a stand-pipe above the kier. A hollow plaiting-arm 5, Fig. 1, is carried in a T-shaped trunnion 1 suspended within the kier by a shaft 29 passing through the shell 45 and through the stand-pipe 35 to the trunnion 1 and The trunnion 1 has a bearing 2 guided in a hollow bonnet 3 containing a dished valve 7, ports 4 in which allow liquor to pass from the pipe 36 through the stand-pipe 35 to the trunnion 1 and the hollow arm 5. The valve 7 normally covers ports 6 leading direct to the kier. Draw-rollers 8 - - 11 on the arm 5 are rotated by bevel-wheels 12, 13 driven from a shaft 46 driven in turn by gears 14, 14<1> from a shaft 40, which is driven from a shaft 34, passing through a stuffing-box 43 on the shell, through gears 37, 39, 38, Fig 3 The arm 5 is reciprocated from the shaft 40 by cranks 15 and rods 16. The shaft 29, at the same time, swings the arm through a pinion 28 driven from a countershaft 32 through a worm 21, wormwheel 22, adjustable crank-levers 24, and a rack 27. The countershaft 32 also drives the shaft 34. The fabric passes through guides 19, 20 to the draw-rollers 8 - - 11, one rope of fabric at each side. The arm 5 is meanwhile swung and reciprocated while, as the fabric runs through the draw-rollers, it is saturated with liquor from the arm 5 before it passes through the nozzles 17, 18 to the kier, where it is laid in folds. When the plaiting is completed, the apparatus is lifted by the screw and nut 44, whereby ports 6 are opened and liquid connexion to the arm 5 closed by the top of the trunnion 1, liquor being thus admitted direct to the kier during the boiling process. When used with open circular kiers, the bonnet 3 is bolted direct to the stand-pipe 35 and is supported in guides over the kier. When applied to open straight-sided kiers, the stand-pipe is mounted on a wheeled carriage running on rails 19<1>, 20<1>, Fig. 5, in girders 19, 20. The girder 19 carries a rack 52 connected by gearing 49, 50 with the shaft 29. The machine thus runs to and fro along the rails, and the worm 21 is carried on a long sleeve on a squared countershaft 32 to allow of this motion. The trunnion is carried by bolts 51 from the stand-pipe 35 The pipe 36<1> is made flexible. The arm 5 and the draw-rollers are operated as before.

Title: Improvements in and relating to rubber articles and the manufacture thereof
IPC: C08L7/00
Filed: 1931-02-23
Abstract: The flexing capacity of rubber is increased by the addition thereto before vulcanizing, of a small amount of a mineral acid or a carboxyl-containing organic acid, and a carboxyl-free benzene derivative which has a coagulative effect on proteins, and which diminishes the alkalinity of the rubber.  Phosphoric acid is preferred, while the most suitable benzene derivative is one having hydroxyl and nitro substituents, particularly picric acid. Picrates, such as the double picrates of naphthalene or anthracene, naphtols, cresols, phenols, 2, 4, 6, tribrom phenol, trinitro resorcinol are also efficacious.  The picric acid &c. may be incorporated in the rubber mix in any suitable manner, such as by milling, diffusion, solution in phenols.  The acids employed should be capable of decomposing alkali proteinates and soaps. The most marked improvement is evident in alkaline rubbers such as whole latex rubber, and alkali reclaims.  The invention is mainly applicable to articles containing textile insertions such as tyres, hose, belting.  Specifications 178,811, [Class 140, Waterproof &c. fabrics], and 367,183 are referred to.  Numerous examples are given in the Specification.

Title: Improvements in projectile fuses
IPC: F42C19/08
Filed: 1925-03-02
Abstract: 252,773. Pearson, C. H. March 2, 1925. Projectile fuzes.-Relates to fuzes of the kind in which a rotatable setting cap 14, enclosing the fuze mechanism such as a clockwork, is connected to the fuze body 10 by a number of segments in grooves 15, 16 in the fuze body and cap respectively. According to the invention, means are provided for adjusting the position of the segments in the groove to permit the regulation of the frictional grip between the cap and the fuze body and the removal of the cap, if required. As shown in Figs. 2 and 3, two large segments 17, 18 and two small intermediate segments 19, 20 are used. The thickness of the segments is equal to or less than the depth of the groove 15 in the fuze body; this enables them to be sunk into this groove and the cap 14 slipped into position over them. Screws 23 are then screwed through holes in the cap into tapped holes in the large segments 17, 18, which are thus dragged partly out of the groove 15 and into the groove 16 and lock the cap in place. Other screws 26 are screwed into tapped holes in the cap and their reduced ends enter holes in the small segments 19, 20, which are thus pressed against the fuze body and determine the amount of frictional grip between the cap and the fuze body. If the screws are left out accidentally when the projectile is discharged, the centrifugal force on the segments is sufficient to retain the cap in place. In a modification, Fig. 5, segments 27 are screwed up by screws 23 against adjustable screw stops 28.

Abstract: 552,441. Ammunition cartridges. YODER, H. O. May 5, 1941, No. 5817. Convention date, May 6, 1940. [Class 9 (i)] [Also in Group XXII] Cartridge cases for shells &c. are produced by making a tubular body from strip stock, for example as described in Specifications 438,790, 439,105 and 440,472, [all in Group XXII] and uniting it to an end or base produced separately as by forging. Strip from a coil 2B, Fig. 1, is fed by rollers 2a through a succession of means (not shown) that form the strip into a close jointed tube electrically welded at 3a. After passing from seaming means (not shown) the tube is sized and trued at 4, straightened at 5 and cut into blanks at 6. The blanks are trimmed and faced to length between opposed cutters 8, Fig. 7, and then necked in dies and if required flanged at the base end. The bodies are assembled on the forged bases 11, Fig. 13, together with a ring 13 of brazing material such as copper wire for completion of the joint by heating. The rings are made by coiling wire on a mandrel 14, and cutting off individual coils at 15, Fig. 16. The ring 13 may be assembled on the outside of the body. In a modification the base 17, Fig. 23, is formed with a channel to receive a flange 16 and the joint is made by turning down the flange 18 either in dies or by rolls 20. The joint is completed by brazing, after a forging operation to reduce the flange to standard dimensions. In a further modification the body has an intumed flange and the base an inner flange that is swaged down on to it prior to brazing. In a further modification the end of the body is upset at 22, Fig. 27, and the base is formed with a downturned flange 23b. After assembly this flange is brought back to its normal position and the upstanding inner flange is swaged to the form shown in Fig. 30, the joint being completed by a copper wire 13 and brazing as before. The brazing may be effected by passing the cartridges on end on an endless conveyor through an electrically heated furnace into a cooling chamber with water-cooled walls. Both furnace and chamber have a hydrogen atmosphere and the entrance to the furnace and the exit from the chamber are sealed by overlapping reducing flames.

Abstract: 608,481. Electric resonators. SPERRY GYROSCOPE CO., Inc. Feb. 25, 1946, No. 5834. Convention date, Feb. 24, 1945. [Class 40 (viii)] An attenuator for high-frequency electric energy comprises in cascade three or more similar lengths of high-frequency conduit having a characteristic admittance greater than the equal terminating admittances between which the attenuator is to be connected, each length being approximately equal to one-quarter of a wavelength therein of the high-frequency energy and between each length there are disposed equal shunt dissipative admittances in number one less than the number of lengths of conduit. In the example shown, the attenuator is formed by a coaxial line 11 and 13 divided by thin conducting elements 31 into similar lengths which contain dielectric plugs of polystyrene. The elements 31 may be formed of carbon deposited on the ends of the polystyrene blocks. The inner conductor 11 may be composed of sections embedded in the blocks and connected by pin-and-socket connections. The use of a solid dielectric enables the line 13 to be of the same diameter as the air-filled lines to which it is connected at each end. If the line 13 is airfilled, its diameter must be less than the connecting lines or the diameter of the internal conductor 11 must be increased. Specification 482,420 is referred to.
