Abstract: 313,503. I. G. Farbenindustrie Akt.- Ges. June 12, 1928, [Convention date]. Cellulose xanthates, processes for making filaments from.-Viscose is spun in a bath containing a lower aliphatic sulphonic acid such as methionic acid, oxymethylene sulphonic acid, oxymethylene disulphonic acid, or methine trisulphonic acid. The baths may contain also mineral acids, salts, and organic additions other than the sulphonic acid, and they may be preceded or followed by other baths. The baths are particularly suitable for spinning non-matured viscose made from non-matured alkali cellulose. In one example, non-matured viscose is spun under specified conditions in a bath comprising water 23, sulphuric acid 34, and isethionic acid 43 per cent, the threads being preferably suhjected to a subsequent coagulation with sulphuric acid on the spool. The spinning may be accompanied by stretching and the stretched threads may be treated on the spool to avoid shrinkage, for instance with water-soluble organic substances such as alcohols, ketones, aldoses and ketoses, or with solutions of electrolytes. In another example, non-matured viscose is spun under specified conditions in a bath comprising water 41, sulphuric acid 40, and acetaldehyde disulphonic acid 19 per cent, and in a further example a bath is used comprising water 31, sulphuric acid 41, and methionic acid 28 per cent.

Abstract: 181,831. Gillespie, W. M., and Buckley, P. March 21, 1921. Metals, depositing; electrolytes, circulating; electrodes.-Metallic powders for industrial and decorative purposes are obtained by electrolysis, using an anode of the required metal, the current density being chosen so that the metal is deposited on the cathode in a finely-divided, non-coherent and non-adherent crystalline form; the electrolyte is passed rapidly between the electrodes so as to carry away the powder, and then passes through a separator, and, if necessary, a regenerating vat, from which it is returned to the cell or cells by a pump. The current density may be 20 amp. per sq. ft., and the electrolyte velocity 10 ft. per sec. The electrodes may be 3/32 inch apart. The cathode may be of aluminium or copper and may be stationary or may revolve or reciprocate. The powder may be separated from the electrolyte centrifugally or by levigation or filtration, and is washed, dried, and, if necessary, polished. In obtaining bronze powder from scrap metal, the electrolyte may be a saturated solution of copper sulphate together with sulphuric acid. 36 cells in series are used, with a current of 1,000 amp. and a pressure of 36 volts. A 50-volt generator is used, driven by a motor which also drives the pump and the washer, polisher, and drier.

Title: Improved apparatus for extracting and replacing the detachable bases of cartridge cases of projectiles
IPC: F42B33/06
Filed: 1932-06-28
Abstract: 384,223. Cartridge loading and unloading apparatus. SCHNEIDER ET CIE, 42, Rue d'Anjou, Paris. June 28, 1932, No. 18279. Convention date, Aug. 20, 1931. [Class 9 (i).] An apparatus for removing and replacing the base Z<1>, Fig. 4, of a cartridge case Z fitted with a projectile Y, in order to change the propellent charge, comprises a single frame A containing an extractor E around the cartridge case, a mechanism for the operation of the extractor, and a pivot A<1> on the frame A for supporting the replacing mechanism. The cartridge is placed in a tube B which makes a sliding fit in the extractor E and is prevented from rotation relatively thereto by a pin F on the tube B in engagement with a longitudinal slot B<1> in the extractor E. The projectile rests on a bracket O at the front end of the tube B. A lever I is pivoted on a pin G carried by the tube B and has an eccentric H connected by a link K, Fig. 3, to lever M pivoted at N on the tube B. To remove the cartridge base, the lever I is turned up ; the first part of the movement is about the pin G and serves to clamp the cartridge case firmly between seats b, b in the tube B and a boss m on the lever M ; during the rest of the movement of the lever I, the cartridge, the projectile, the tube B, and the extractor E are all rotated, and a screw connection e between the extractor E and the frame A forces the extractor backwards to withdraw the base Z<1> from the cartridge case Z. After the charge has been altered, the lever I is reversed and the base Z<1> replaced in readiness to be forced home. This is done by a plunger device carried by a bar R mounted on the pivot A<1>. The bar, which is normally aside against a stop is swung down on to a support A<2>, Fig. 9, then a lever P is also swung down and the screwthreaded hub p thereof, acting on the screw stem Q slidably guided against rotation in the bar R by a key w, drives this screw forward and forces the base Z<1> home into the cartridge case. The head X of the screw stem, which bears on the base Z<1> is connected to the stem by a flexible joint. When the lever P begins its downward swing, a cam on its hub forces a spring retracted bolt S<1> into a hole in the support A<2> to hold the bar R in position, and when the lever has completed its stroke, it may be locked by a spring stud U, which can be pulled back and turned by hand to unlock the lever and allow it and the bar R to be turned back to inoperative position.

Abstract: 238,685. Fassinger, C., and Thomas, C. July 31, 1924. Forging bolts; dies.-A boltheading machine comprises a heading-block which forms the head by pressure applied axially of the bolt, the fin formed in this operation being subsequently reworked into the bolt head bv forcing the head through a tapering aperture. Blanks B, Fig. 3, are fed by hand or an automatic feeding device to an incline 105 and one is lifted over a shoulder 108 each time a slide 71 moves down, by a lever 116 connected to the slide by a rod 118. The blank thus separated is held by a spring clip 110 until seized by a gripper 78 the moving jaw 85 being opened against the action of a spring 82 by a fixed cam 126. The gripper is moved horizontally and vertically by slides 50, 71 operated respectively by a cam 55, Fig. 1, link 60 and lever 63 and by a cam 96, Fig. 3, driven through a clutch 99 and bevel gearing 94, 93, 90, 9 and spur gearing 8, 53, Fig. 1, from the main shaft 4. The blank is presented by the gripper successively to dies 33, 36 and 34, 37 in order that a head may be formed by dies 43, 44 reciprocated by a crank. The first operation forms a rough head C, Fig. 4, and fins D and the second folds these fins against the head, by reason of the flared mouth 142 of the dies 34, 37, and gives a finished head. The partings of the dies 34 37, are not in the plane of their axis so that the longitudinal fins, formed on the shank by the dies 33, 36 are removed by the dies 34, 37. The gripper 78 is opened during the second operation to allow the necessary axial movement of the blank by an arm 103 operated by a, cam 98 which engages the tail of the moving jaw 85 and is opened again to discharge the finished blank by being moved into engagement with the arm 103 in its lowest position. The dies 33, 34 are mounted in a lever 28 pivoted at 29, pulled back by a spring 30 and pressed forward at the desired moment by toggles 26 which are operated through a relief slide 15 and spring 17 by a slide 11 and cam 6. The slides are returned by a spring 22. The position of the blank relative to the first dies 33, 36 is determined by an adjustable stop 130, Fig. 1, and a yielding pusher connected to the slide 11. The dies 33, 36, 34 and 37 are secured in their holders by dogs 35, 38.
