Title: A new method and apparatus for the manufacture of playing cards
IPC: A63F1/02
Filed: 1932-07-07
Abstract: 394,141. Manufacturing playing-cards. WATSON, N. V., 3, Woodhouse Cliff, and WADDINGTON, Ltd., J., Wakefield Road, both in Leeds. July 7, 1932, No. 19225. [Class 132 (ii).] A method of manufacturing playing-cards consists in feeding a long length of the card material in a continuous manner through successive trimming, printing, drying and pressing stages to a shaping stage. In a modification, the card material is fed " semicontinuously," i.e. after the length of material has been fed through certain operations, there is a break, and subsequently the material passes through further operations. In the apparatus shown for carrying out the above method, the card material 1 is fed from a roll 2 round pulley 4 and floating roller 6 to form a loop 5 to give a reserve feed of material to the apparatus in case of faults. The material passes between cleaning rollers 9, a suction pipe 10 removing the particles, to rotating knives 11 which reduce the strip to a standard width. The strip is dried in chamber 12 (heater 13 and fan 14) and the coloured backs of the cards are printed at 17, preferably by a photogravure process. After further drying at 19, 20 the strip is cooled by blower 21, and printing rollers 22 print the faces of the cards in a complete pack or set. An arc lamp 23 in casing 24 is used to show the back and front printings of the cards simultaneously to ascertain if the back and front printings are in register. Subsequent to being dried in chamber 25, the strip is coated with a waterproof material by rollers 26 and then dried in a chamber 27. Rollers 29 reduce the strip 1 to the desired thickness, impression rollers 31, 32 apply a suitable grain or texture to the card surface, and gauge 30 indicates the thickness of the material, so that the rollers 29 may be adjusted to maintain a standard thickness. After polishing and finishing by brushes or polishing rollers 33, the strip 1 of the card material is cut at 34 into separate cards. This punching machine 34 is arranged to cut the strip into a series of cards stacked in sets or complete packs. These cards are delivered to a receptacle (e.g. mounted on endless band 37 or a drum having separate divisions) which is automatically moved when a complete pack or set of cards has been delivered. A push rod is associated with each punch to eject the cut-off card rapidly. Roll 3 is an emergency roll which may be drawn off to take up a break in strip 1. At appropriate parts of the operations the strip may be accurately positioned by holes in its edges engaged by sprocket teeth. The backs of the cards (apparatus 17) may be printed by means of a lithographic offset printing process to enable line, half-tone, photographic and colour prints to be produced.

Filed: 1927-07-21
Abstract: 279,391. Rainbow Light, Inc., (Assignees of Machlett, R. B.). Oct. 20, 1926, [Convention date]. Vacuum tubes.-Luminous electric discharge tubes with a single discharge path between interior electrodes in a monatomic gas are provided near each electrode with a deposited mirror of alkali metal upon the interior walls of the tube, the mirror being out of contact with, and substantially wholly in advance of, the electrode. The mirror is preferably of caesium and the atmosphere is neon at 8 mm pressure, argon, helium, krypton or xenon. Electrodes of area less than 1, for example, equal to 0.9. square decimeters per ampere may thus be used without undue heating or disintegration and the ohmic resistance of the tube is increased, so increasing its luminous efficiency. The tube may be shaped as symbols &c. in advertising or may be used as beacon lights in aerial navigation. The enlarged ends 2 of the glass tube 1 may be conical or pear-shaped, caesium being distilled into the tube after exhaustion but prior to introducing neon and being driven, by heating to form a deposit 6 in front of the copper shells 4 forming electrodes. The tube may be purified by baking to a high temperature during exhaustion and by introducing caesium vapour, on subsequently cooling, the caesium mirror is formed.

Title: Improvements in or relating to pickling installations
IPC: C23G3/02
Filed: 1960-06-03
Abstract: In a method of recovering from the pickling liquid of a pickling plant the acid carried along with the pickled product, the latter is rinsed with a sufficient quantity of water to obtain a substantially complete elimination of the acid, the rinsing liquid thus obtained being concentrated in an evaporator by indirect heating and returned to the pickling vats whilst the steam produced by the evaporator is used as heating steam.  As shown, strip A is pickled in vats a-d, while the acid flows in countercurrent relationship from vat d to vat a.  The pickled strip is rinsed by spray nozzles 3 fed from rinsing vat 1, then by immersion in vat 1, then by device 4, and finally by device 7. Rinsing liquid from vat 1 is fed through line 11 to evaporator 8 (if desired, the evaporator may also be supplied with liquid from the iron salts separating apparatus 13).  The resulting steam and concentrated liquid are separated in unit 9, the former being passed through line 14 to vats a-d as a direct heating medium while the latter is introduced into vat d through line 12. <PICT:0949680/C3/1>

Abstract: 580,415. Projectiles. TWYFORD, J., and DONIGER, M. B. Dec. 1, 1943, No. 20054..[Class 9 (i)] [Also in Group XXII] Bullets, particularly of the incendiary type and having an outer casing with or without an internal sleeve, are made either with an external casing containing a sleeve formed by helically coiling wire -or strip metal and machining the forward end of the helix to mate with the interior of the casing, or with an outer casing formed from a helically coiled wire or strip metal and having a nose piece and a base piece fitted thereto and without an internal sleeve. The longitudinal strength is thus groat compared with the bursting strength. The strip metal may be of rectangular; circular, or D- section and the coiled sleeve plain cylindrical or of different diameters at different parts and may be open or closely wound and the adjacent turns welded, brazed or soldered. In making a bullet as shown in Fig. 1, a mild steel strip 3 may be used of section shown in Fig. 2 with a wider face 3a on the part to form the outside of the coil so that during coiling the compression or tension stresses at the inner and outer parts cause the strip to assume a parallel-sided form with adjacent turns abutting closely together. A continuous coil may be formed and lengths machined to taper form at their forward end and then cut to form the sleeves in a hollow spindle capstan lathe. Interior or exterior grinding may -also be effected. The sleeve which contains the incendiary charge 4 is placed ina casing 1 with a detonator in the nose 2 and with a packing piece 5.
