Title: Improvements in or relating to machines for closing collapsible tubes
IPC: B65B7/14
Filed: 1936-05-13
Abstract: 475,412. Closing collapsable tubes. STOKES MACHINE CO., F. J., and WESTIN, C. J. May 13, 1936, No. 13547. [Class 94 (i)] A machine for closing collapsable tubes comprises an intermittently rotated dial 21, Fig. 1, on which are mounted cups 20 for holding the tubes A. The open ends are first spread before arrival between jaws 27, 28 which close in and flatten the walls over an extent sufficient to provide a flattened stock for all the subsequent folds. To compensate for the shortening of the tube caused by this action, the supporting cup 20 is lifted off its seat 30 by a member 32 actuated by adjustable mechanism. The edges projecting above the jaws are turned down through 90‹ by a folder 33, which, when the jaw 28 is withdrawn to the right, turns down into the position shown in Fig. 3. In this position, it turns down the folded portion of stock against the action of a spring 41, and is withdrawn to the left to enable the jaw 28 to advance again and flatten the fold. The folder 33 is recessed at 34, the bottom of the recess forming an angle of about 10‹ with the flank 36 which acts as a cam to lift the folder during its withdrawal, and to prevent dragging the fold back with it. After a movement of partial rotation, the tube is raised before being gripped by jaws 57, 58 and a creaser 96 co-operates with a folder 59, Figs. 6 and 8, to form a tuck. The jaw 57 is retracted, and the folder 59 swings down under the action of a spring 77 to make the folds shown in Fig. 8. The creaser 96 is mounted on an arm 95 resiliently held by a spring 92 in angular relation with an actuating arm 90, adjustment being made by a stud 89 and nut 88. The position of the creaser 96 is adjustable by set screws 196, 197. The jaw 57 again advances and flattens the lower folds as shown in Fig. 9, pushing up the folder 59 by the action of the edge on the sides 64. The folder 59 moves to the right and the recess 62 turns down the upper folds flat on the jaw 58, which then retires and allows the folder 59 to turn into the position shown in Fig. 11. A return of the jaw 58 pushes up the folder 59 and flattens both sets of folds. Crimping and embossing is carried out at the next station to produce the effects shown in Fig. 14. A movable presser jaw 125, Fig. 16, having a punch 126, forces the folds against a fixed punch 127 in a recess in which the type is adjustably held by a head 132 and screw 131. The punches have interlocking serrated faces to effect the crimping.

Title: Improvements in or relating to the production of nitrogen-free argon
IPC: F25J3/04
Filed: 1950-05-31
Abstract: 680,373. Separation of argon from air. GES. FUR LINDE'S EISMASCHINEN AKT.-GES. May 31, 1950 [June 20, 1949; Aug. 19, 1949], No. 13622/50. Class 8 (ii). Argon is separated from crude argon-nitrogen-oxygen fraction withdrawn from the low pressure column of a two stage air separation column (not shown) at a point where the oxygen and nitrogen contents are about equal by first removing the nitrogen by distillation in a column 2 Fig. 1, and subsequently separating the argon and oxygen in a separating column 11. In operation the crude argon mixture, after being cooled in a countercurrent heat exchanger 1 and a coil 6, enters the column 2 through a duct 7. Part of the separated nitrogen, which also contains argon and oxygen residues, serves to cool the exchanger 1, and the remaining nitrogen after expansion at a valve 25 cools high pressure nitrogen traversing an exchanger 8. This high pressure nitrogen after being liquefied in coils 17, 18 and further cooled in an exchanger 19 is expanded at a valve 20 and cools a condenser 27, thereby providing the necessary cold for the separation in column 11. The thus warmed nitrogen is discharged through exchangers 19, 8. Liquid argon-oxygen mixture from the base of the column 2 after expansion at a valve 10 is rectified in the column into pure argon gas which leaves through a duct. 14, and into substantially pure liquid oxygen which is forced by a motor driven pump 15 to the vaporising space of a condenser 4 at the head of column 2, from which the major portion of oxygen gas is discharged through a duct 21; the remainder being returned to the column 11. In a modification the cold requirement for the argon-oxygen separation column 36, Fig. 2, is provided by expansion of crude argon and of compressed air in a crude argon circuit and a compressed air circuit respectively. In operation crude argon, including the portion to be separated, after traversing a compressor 32, an aftercooler 33, a countercurrent heat exchanger 34 and a liquefying coil 46 is expanded at a valve 37 and vaporised in a coil 38, thus cooling the head of the column 36; the portion of crude argon to be separated being expanded at a valve 40 before entering the distillation column 39. The crude argon circuit is completed through exchangers 60, 34. The compressed air after traversing countercurrent heat exchangers 63, 56 liquefying coils 41, 47 expansion valves 43, 48 and the exchanger 60 is divided into one portion which is expanded at a valve 44, and serves as sprinkling liquid in the column 39, and a second portion which after expansion at a valve 49 is vaporised in condenser tubes 52, thus cooling the head of the column 36. Vaporised air is joined by nitrogen from the column 39 before entering the exchanger 63, liquid argon product leaves at a duct 59 and oxygen gas by a duct 55. Specification 358,842 is referred to.

Filed: 1936-05-18
Abstract: 460,556. Enamels and glazes. SCHUTTE AKT.-GES. FUR TONINDUSTRIE. May 18, 1936, No. 14087. Convention date, March 14. [Class 56] [Also in Group X] To produce the appearance of terra sigillata on ceramic ware, the articles are coated with an aqueous suspension of clay peptized with a small percentage of alkali and, if desired, protective colloids such as humin, so as to have a viscosity of 10 centipoises or less. The viscosity is adjusted by varying the quantities of water, alkali, and protective colloids. The suspension is allowed to stand for 24 hours, and is used after removing deposited material. As examples, a suspension of 38 per cent clay and 62 per cent water gives with 0À 1 per cent NaOH (calculated on the clay) a viscosity of 11À65 cps. ; with 0À3 per cent NaOH a viscosity of 11À55 cps. which is lowered to 6À825 cps. on adding 0À6 per cent humin ; and with 0À7 per cent NaOH a viscosity of 8À4 cps. As a further example, a clay and water suspension of sp. gr. 1À2, on adding 0À5 per cent NaOH shows a viscosity of only 2À9 cps. Unfired articles are dipped and fired at about 1000‹ C. Biscuit-ware and fired articles are coated and finally fired at 600‹ C. Colours may be obtained by metal salts soluble in the suspension.

Abstract: 933,229. Two-part couplings. UNITED STATES ATOMIC ENERGY COMMISSION. April 12, 1962 [June 26, 1961], No. 14091/62. Class 38 (1). A coaxial connector provided with a bayonet catch and a sleeve with splines which prevent relative rotation after engagement, has a spring which acts as the outer connector of the plug portion and which ejects this part when the bayonet catch is released. The socket part, Fig. 2, consists of a socket contact 18 mounted in an insulating insert 14 which is partially enclosed by a metal cover 24 which is threaded to enable the connector to be fixed to a panel, and carries at its forward end two bayonet pins 38 and a collar 33 with grooves 34 separated by lands 35, Fig. 4 (not shown). In the plug part, Fig. 3, the central core 44 of a coaxial cable 33 is attached to a pin 48 which is mounted in an insulating insert 40 enclosed in a metal case 68 which carries at its forward end a spring-loaded sleeve 87 which is prevented from rotating relative to the plug body by means of splines which engage grooves on the outside 81 of the plug case. The outer braid of the cable 13 is gripped by a bushing 49 which screws on to the covering 47 and a metal sleeve 57 holds the braid in contact with a helical metal spring 54, held in position by tongues 72, which acts as the outer contact and also as the ejection means. The inside of the metal case 68 is provided with an annular groove 92 to which two slots 93 lead. When the plug is inserted in the socket the pins 38 enter slots 93, sleeve 87 abuts collar 33 and spring 54 abuts the end of the socket case 37. On further insertion of the plug the springs 54 and 83 are compressed. When the bayonet pins 38 enter the groove 92 the plug can be rotated in either direction through an angle of 45 degrees, at which position the sleeve 87 snaps forward due to engagement of its splines with the grooves on the collar 33. This prevents the connector from being rotated. The plug is removed by pulling back the sleeve 87 and rotating the plug until the pins 38 enter the slots 93. The spring 54 then ejects the plug portion. The cable is sealed by packings 77, 78 and a seal 95 is provided which abuts the conical face of the socket case 37 when the plug is engaged. In a modification, Fig. 7 (not shown), a sealing gland for use with flat coaxial cable is described.
