IPC: B29C49/00
Filed: 1970-07-30
Abstract: 1287044 Seaming non-metallic sheet material E HARTMANN and B SEILER 30 July 1970 [26 Aug 1969] 36975/70 Heading B5K A flat tube is produced from two thermoplastic film strips 1 by intermittently drawing off the strips 1 from two supply rolls 3 by reciprocating clamping jaws 8, applying hot air to the longitudinal edge zones of the strips 1 by blowers 9 which are removed from the edge zones at each forward feed stroke of the jaws 8, and pressing the strips between rollers 6 to weld together the heated longitudinal edges. The apparatus comprises a fixed frame 13 and a vertically reciprocable frame 12. The frame 13 carries two guide pulleys 4 for the strips 1, a pipe 14 for the supply of compressed air, and a pair of clamping rollers 11 rotatable in the direction of the arrows 11b only. The frame 12 carries guide pulleys 5 for the strips 1, the pressure rollers 6 with guide plates 7, the clamping jaws 8 and the hot air blowers 9 having nozzles 10. In operation, the apparatus is set up by passing the leading ends of the strips 1 over the pulleys 4, 5, between the rollers 6, 11 and between the jaws 8. The jaws 8 are clamped together to hold the strips 1 and the frame 12 is moved downwardly to feed the strips an increment. At the lower position, the jaws 8 are opened to release the strips 1 and, simultaneously, the blowers 9 move inwardly from an outer inoperative position, Fig. 3 (not shown), to the position of Fig. 1. The longitudinal edges of the strips 1 above the rollers 6 are softened. The frame 12 moves upwardly as the heated edges are compressed by the rollers 6 and thus welded together to form a tube 2. When the frame 12 reaches its upper position, the blowers 9 are moved outwardly and the jaws 8 clamp the tube 2. Subsequent downward movement of the frame 12 feeds the strips by another increment. The tube 14 serves for inflating the tube 2 in a subsequent packaging apparatus.

Patent GB-371934-A (GB)
Abstract: 371,934. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Shipley, B. M.; 2021, Catalpa Drive, Dayton, Ohio, U.S.A.) Jan. 30, 1931, No. 3015. Convention date, Jan. 30, 1930. [Class 100 (iv).] Locking-devices; web-feeding arrangements.- In a cash register, when the voucher-feed rollers are separated the machine is locked against release. By means of a proprietor's key, however, the locking-mechanism may be disabled. As shown applied to the machine described in Specification 248,763, [Class 100 (iv), Typewriters &c.], the voucher strip 80 passes between a feed roller 81 and a pressure roll 85 supported by arms rigid with a sleeve mounted on a stud 88. The roll is forced upwardly by a coil spring bearing at one end against a flat bail 91 carried by arms on the stud and at the other end against a pin on one of the roll-supporting arms. The pressure roll may be separated from the feed roller by rocking the sleeve and arms counter-clockwise directly or by manipulating a hand-lever 114 spring-connected with a bell-crank 116 camedged to control the arm 112 extending from the bail. Normally the separation of the rollers is prevented by a hook 95 which forms part of a lever 96 and engages a lug 99 on the pressureroll frame. When this lever is rocked counterclockwise however, to allow the separation, a block 98 on the lever passes to the left of the bent end of a link 131 and prevents release of the machine. For this purpose the release shaft 33, Fig. 2, has an arm carrying a stud 150 to cam a link 148 to the left when the machine is released. This effects through a rock-shaft 143 a similar movement of a link 140 notched at 139 to receive a stud serving to couple the links 140, 131 together. Thus, provided the stud is functioning, the link 131 tends to move to the left when the release shaft is freed, and if the block 98 is in the way the machine cannot be released. Similarly after release of the machine the lever 96 cannot be shifted to allow the feed to be prevented. In order to disable this mechanism a key may be applied to a barrel lock 137 to rotate an eccentric 135 carrying the coupling stud so as to remove this from the notch in the link 140.

Title: Improved method of forming translucent electrically conducting coatings on bodies of insulating material
Inventor: TUCKER JOHN MARTYN KENT
IPC: H01J29/28
Filed: 1954-12-24
Abstract: A translucent electrically-conducting coating is formed on a body of insulating material, e.g. glass, ceramic or mica, by applying to the surface thereof a solution of a stannous salt while the body is at a temperature below that at which an adherent electrically conducting coating will be formed, and then heating the surface of a higher temperature so as to form the required coating.  Suitable solutions comprise stannous chloride, methylated spirits or alcohol, hydrochloric acid, ammonium thiosulphate, and ammonium sulphide solution saturated with sulphur, with or without antimony trichloride.  The invention is described as applied to coating cathode-ray tube envelopes, which are rinsed with the solution, drained and dried, and then heated to between 500 DEG  and 850 DEG C.  After cooling, the coating is rinsed with hydrochloric acid, followed by an alkaline wash and a water wash if required, and a luminescent screen is deposited over it. To prevent the side walls from being rendered conductive, they may be wiped free of coating material and protected by a metal screen during heating, or the heating may be localized.  The invention may also be applied to form the signal electrodes of television pick-up tubes.

Abstract: 971,158. Finishing yarns. DEERING MILLIKEN RESEARCH CORPORATION. Nov. 11, 1960 [Nov. 12,1959], No. 38839/60. Headings D1F and D1W. In a process of bulking single or multi-filament, synthetic thermoplastic e.g. nylon, yarn, the degree of heating of the yarn prior to its passage over a sharp crimping edge is intermittently altered e.g. by random, periodic, abrupt and/or progressive adjustment of the contact of the yarn with a heat source. The final yarn has linearly alternate unbulked and bulked segments with the latter of constant bulk in the linearly central portions and of gradually increasing bulk from the intersection of the bulked segment with the adjacent unbulked segments in the direction towards the central portion. The bulk and/or stretch i.e. latent crimp, effects may be fully developed e.g. by subjecting the yarn to hot moisture or air or by contact with a hot surface, before or after weaving or knitting the yarn into fabric. As shown, yarn Y passes from a bobbin 11 through guide 13, tensioner 15, intermittent crimping device 17 to a ring and traveller take-up 18. In the device 17, the travelling yarn is removed from engagement with a heater strip 19 at predetermined intervals by an arm 25 which is raised and lowered by oscillation of pivoted shaft 27 due to intermittent energization of solenoid 31 under the influence of a signal generator 37 moving a lever arm 35 against a return spring 33.
