Title: Improvements in machines for working glass tubes under heat
IPC: C03B23/11
Filed: 1946-05-29
Abstract: 619,965. Working glass tubes. SHAW, G. S. May 29, 1946, No. 16286. [Class 56] Relates to the waisting or complete severing of glass tubes by conveying them past heating means and drawing them out by flexible belt means which contacts them at an inclination to their direction of traverse and is driven longitudinally to rotate them and to apply a transverse thrust to them. According to the invention the conveyor causes the tubes to follow a curved path so that the flexible belt or belts extending thereover will contact every tube, even if their diameters vary. As shown, the tubes are picked up from a chute 2 by semi-cylindrical grooves 3, 4 in drums 5, 6 rotated by a suitable drive to their shaft 7 ; flexible belts 13, 14 driven faster than the drum peripheries hold and rotate the tubes, their runs concentric with the drums diverging whereby, as the tubes are heated by a gas burner 10, their ends are drawn apart ; the extended tubes, or pairs of containers, are conveyed away for inspection and annealing by a chute 16 and conveyor 17. The tube ends, heated by auxiliary burners, may be flared by mandrels 23, Fig. 3, carried by a plate 22 on the shaft 7 and advanced by springs 24, under control of a tapering slot 25 in a stationary plate 21, or may be grooved by contact with a rib 27. Between the drums, tools to shape the container bottoms may be fixed. According to the Provisional Specification, such tools may be movable with the drums and controlled by stationary cams, and the tube holding and rotating means and extending means there described comprise respectively a stationary belt, and a belt rotating about its own axis.

Title: Apparatus for continuously washing running lengths of material
Inventor: OLSON EDWARD STURE
IPC: D06B3/20
Filed: 1957-05-23
Abstract: A long length of textile material is liquid-treated in a partly covered tank 11 in which is mounted a perforated cylinder 32 oscillated by an electric motor 87 and gearing.  The tank and cylinder are supplied with a circulating flow of treating liquid from a pump 155 which withdraws the liquid from the other end of the tank and returns it to the cylinder via conduit 161 and flexible pipe 163. The flow assists in agitating the material and moving it through the cylinder from inlet port 39 to the outlet 41, and radially directed baffles 49 are provided on the cylinder to transmit a shock wave to the liquid therein.  The material is also moved through the apparatus by overhead feed and withdrawing rollers 97, 98 respectively, having roughened surfaces and co-operating with shoots 123, 125 supplied with lubricating water through pipe 178.  The cylinder is provided with flexible wipers 183 which guide the material into the cylinder and retain it therein, and the liquid is heated by steam passed through perforated pipes 131 connected to a main 133.  The material may be either attached to a leader for its passage through the apparatus, or if only one length is to be treated it may be stitched to form an endless band.  Several machines may be operated in series at different temperatures. <PICT:0817384/IV (c)/1> <PICT:0817384/IV (c)/2> <PICT:0817384/IV (c)/3>

Abstract: 240,571. Broadbent, D., and Teague, W. July 11, 1924. Vibration-dampers. - Relative vertical movements between the frame and axle of a vehicle are checked by a vertical flexible member which moves between gripping members adapted to exert a bending action on the flexible member. In the construction shown in Fig. 1, a flexible member 9 having a reinforced end pivoted to the frame 10 is slidable through a box-like part 1 pivoted at 2 to the axle 6. The part 1 contains convex and concave gripping pads 13, 14 pressed together by a screw 15, as shown in Fig. 3. In a modification, the blade is tapered so that the resistance increases as the displacement of the spring increases. In a further modification, two springs held a short distance apart at one end slide between convex and concave gripping members, the resistance to bending being greater the greater the distance of the gripping members from the fixed ends. In the construction shown in Fig. 7. two flexible elements 9 form a resilient wedge sliding between rigid shoes 22.

Title: A fluoride volatility process for the recovery of uranium
IPC: G21C19/48
Filed: 1954-06-04
Abstract: Material containing uranium is treated with halogen fluoride in the liquid phase, the product is fractionally distilled, and a uranium hexafluoride-rich fraction is separately collected.  The preferred halogen fluoride is bromine trifluoride, but other fluorides referred to are chlorine trifluoride, bromine monofluoride, bromine pentafluoride and iodine pentafluoride. Addition of bromine, antimony pentafluoride, niobium pentafluoride, or tin tetrafluoride to bromine trifluoride increases the reaction rate.  In order to prevent formation of a volatile plutonium fluoride when using bromine trifluoride, bromine and bromine monofluoride may be continuously removed during the treatment by distillation or by addition of fluorine, which reacts to re-form bromine trifluoride.  The process may be used to recover uranium from neutron-irradiated uranium metal or salts e.g. uranyl ammonium phosphate (see Group XL (a)).  When using bromine trifluoride, by-products of the reaction (bromine and bromine monofluoride, or bromine pentafluoride) may be reacted with fluorine, or bromine at 150 DEG  C. to reform bromine trifluoride for re-use.

Abstract: 948,420. Sewing machines. MAN-SEW CORPORATION. May 2, 1962 [May 8, 1961], No. 16825/62. Heading D1G. In a sewing machine which simultaneously produces overedge stitching and a line of through stitching parallel therewith, the overedge stitching is performed at a rate which is a submultiple of the rate at which the through stitching is performed. As shown, two-thread overedge stitching is performed half as fast as two-thread chain stitching. A needle bar 5 carries a needle 8 and 9. Needle 8 co-operates with a threaded looper 23 and a spreader 19 to produce the through stitching. Needle 9 co-operates with a threaded looper 40 and a spreader to produce one edge stitching. The bed shaft drives a shaft 14 carrying a crank pin 16 adapted to rock an arm 18, carrying the spreader 19, in the line of feed. The bed shaft also drives a shaft 20 which, via a pitman 21, oscillates a shaft 22 to rock the looper 23 carried thereby across the line of feed. Looper 40 and spreader 41 are respectively carried by shafts 42 and 46 journalled in a casing 25 mounted on the bed plate 24. A shaft 28, journalled in casing 25, is driven via a universal joint 29 at the speed of the bed shaft, and drives shafts 42 and 46 via 2 to 1 reduction gearing. Looper 40 and spreader 41 thereby co-operate with needle 9 only on alternate penetrations of the latter to produce a stitch length twice that produced by needle 8. A shaft 33, journalled in casing 25, is driven at the same speed as shaft 28, and carries an edgetrimming blade. Specifications 779,132, 802,833, 915,349 and 929,514 are referred to.
