IPC: B41L7/02
Abstract: 133,454. Jean, C. W. Oct. 11, 1918. Roller copying - presses; driving printing- machines; stopping, tripping and like arrangements.-A machine for copying documents on to a web of paper, which is afterwards cut into sheets and perforated, comprises pairs of damping, impression, feed, and preferably also wringing rollers, one roller of each pair being positively geared to a common driving-shaft so as to be driven in unison, and a heated drying-roller between the pressing and feeding rollers. The machine is driven through a clutch which is opened automatically by a timing-gear when the document is copied. As shown, the web 17 of copying paper passes from a roll 15 round a guideroller 18 and between damping-rollers 20, 21, wringing-rollers 22, 23, impression rollers 29, 30, 'round a drying-roller 37, and between feed-rollers 42, 43. The roller 20 is covered with fabric and rotates in a water-trough 19. The roller 23 is mounted in screw-eyes 28 carrying pressure springs 26 and adjusting-nuts 27, and the feedroller 43 is similarly mounted. The impression roller 30 is carried by a lever 31, and its pressure on the roller 29 is adjusted by a screw 35. The drying-roller 37, heated by gas or otherwise, is freely mounted in standards 41, and guide-rollers 39, 40 keep the web 17 in close contact with the roller. The machine is driven by a motor 59 through worm gear 61, 62 and a vertical shaft 63 on which is splined a clutch member 67. The coacting loose clutch member 68 carries a bevel-gear 69 engaging a bevel-gear 70 fast on the shaft M of the roller 29, and the shaft M is positively connected by shafts and bevel-gears to the shafts of the rollers 20, 22, 42. The shaft M is also geared to a shaft 74 to which is secured a timing-disk 110 provided with a notch 111 to receive a roller 112 on a yoke 107 having an arm 109 operatively engaging the clutch member 67. The yoke 107 is provided with a rack 106 engaging the toothed arm 105 of a bell-crank 104<a>, the other toothed arm 104 of which meshes with a toothed hub 99 of an arm 98 pivoted on a pin 100 and engaging in an opening in a longitudinally slidable bar 94. The bar 94 is operated by depressing a treadle, thereby raising the yoke 107 and closing the clutch 67, 68 to drive the machine. The yoke is held raised by the engagement of the plain periphery of the disk 110 with the roller 112 until the disk has completed a revolution, when the roller reengages the notch 111 under the action of a spring 123 and opens the clutch 67, 68. The web 17 passes from the feed-rollers 42, 43 to a cutting and perforating apparatus, comprising a fixed blade 49, Figs. 1 and 5, and a swinging blade 50 pivoted in a bearing 51. The blades 49, 50 support perforating-members comprising a plate 52 provided with punches 53 and a plate 54 provided with holes 55. A plate 56, mounted on the punches 53 and pressed outwards by springs 58 on pins 57, serves to strip the web off the punches. The blade 50 is operated by connexions from the bar 94 comprising an arm 115, roek-shait 116 joumaled in a sleeve 117, crank-arm 118, link 119, and crank-arm 120 on the pivot of the blade 50.

Abstract: 135,535. Marks, E. C. R., (Du Pont de Nemours & Co., E. 1.). Sept. 6, 1918. Acids, concentrating a n d distilling; fi l m evaporators. - Concentrated nitric acid is produced from mixtures of nitric and sulphuric acid, such as the waste acids obtained in nitrating cellulose, containing 3-25 per cent of nitric acid and not less than 64 per cent. of sulphuric acid, by distributing the acids uniformly over pieces of quartz or other material of 2-3 in. diameter in a tower at the lower end of which steam or a hot gas is admitted, the temperature of the vapours leaving the upper end of the tower being kept below 215‹ F. and preferably at or below 205‹ F. The vapours are passed to a condenser, and the uncondensed gases are absorbed in water and returned to the tower. The condensate is 90-99.7 per cent nitric acid. The distributor 9 for the acids entering the tower 1 is formed with liquiddischarging openings 11, and with openings 10 through which vapours from the tower pass to a coupling G leading to the condenser.

Abstract: 737,312. Drilling-machines. WINDER, R. H. B., and NATIONAL COAL BOARD. June 3, 1952 [June 8, 1951], No. 13629/51. Class 83 (3). A drilling-machine for earth &c. comprises a casing 12, a drill tube 10 for holding a bit 31 and extending throughout the length of the casing, means 1, 6, 7 for imparting unidirectional rotary motion to the drill tube, and means 9, 11 whereby the drill tube can be caused to move axially relatively to the casing simultaneously with the rotary motion. A piston 1, carrying rack teeth meshing with a pinion sleeve 6, is reciprocated by fluid pressure and, in one direction of movement, causes the spring 7 to be twisted to grip the tube 10. The sleeve 6 carries a peripheral cam 11 engaging followers 9 on a manually rotatable sleeve 8. By adjustment of the sleeve, the rod 10 can be caused to advance, to be retracted, or to remain axially stationary for each rotational movement of the drill. The retraction movement is caused by the return spring 16. The machine may be fixed in a hole by a head 24 clamped against the walls of the hole by a hydraulically-actuated sleeve 19. A stream of fluid, which may be from the same source as that reciprocating the piston 1 and clamping head 14, is passed between the rod 10 and the sleeve 19, the fluid and detritus returning through the tube.

[Class 23] The material supplied to a centrifugal machine for separating solids and liquids, is fed through a fixed pipe 11 extending to the inner ends of passages 13 which conduct the material to the space between the rotating bodies 1, 4. A twisted partition strip 12 divides the pipe 11 into two helical passages to impart an initial rotary motion to the material. The passages 13 are arranged in pairs, diametrically opposite each other, and they are arranged at different angles to the separator axis so that they terminate at various levels on the periphery of the conical part of the body 1. The ends 15 of the passages are shaped so that the material leaves with a tangential as well as a radial velocity. The body 1 rotates at a different speed from that of the body 4 and carries an helical conveyer 14 constructed as described in Specification 479,872, to assist the separated components to reach the discharge outlets 16, 17.
