Title: Improvements in or relating to methods of manufacturing a wound body containing nb sn
IPC: H01F6/06
Filed: 1965-03-15
Abstract: <P\1> A method of manufacturing a wound Nb3Sn containing body comprises the steps of producing an insulating oxidized niobium foil by heating the foil from 3 to 60 microns thick in an oxidizing atmosphere at 625 DEG  C. to 850 DEG  C., winding a combination comprising a niobium conductor and the insulating oxidized niobium foil so as to form a wound body, and then subjecting the wound body to a thermal treatment at 920 DEG C. to 1200 DEG C., during which treatment Nb3Sn is formed by alloying tin with the niobium conductor. In one embodiment the thermal treatment is carried out in a bath of molten tin or altenatively a tin coated niobium conductor may be used as a source of the tin. Two tapes of niobium foil separated by a tape of oxidized niobium foil were wound on a first split cylinder of Nb3Sn.  The wound coil was surrounded on the outside by a second split cylinder of Nb3Sn and the body was immersed in molten tin. After cooling 1 mm. thick wafers were cut from the coil and placed in liquid helium so that the Nb3Sn was superconductive. According to the Figure the cylindrical Nb3Sn cone 1 is shown with a few of the windings consisting of a spiral 2 of oxidized niobium foil and a spiral 3 of Nb3Sn.

[Also in Division B8] A method of making a packaging container comprises placing a card having an aperture over a mould so that the aperture registers with a cavity in the mould, distending a heated flexible thermoplastic film such as polythene in contact with the side of the card remote from the mould into the cavity to form a pocket, and heat-bonding the film to the card. The heated film 30 is draped over the card stock 18 on the mould 10, and a vacuum pump beneath the mould is actuated so that the film is pressed firmly against the walls of cavities 12 and against the card, being thus also bonded to the card. The card and film are then removed and die cut along lines 27 into individual sections 28 having apertures 23, 24. The sections 28 may be prefolded and stacked, collapsing the pockets. The article to be packaged is placed into the pockets, and the abutting inner faces of the two halves are reheated and pressed together, thus also reinforcing the bond between the card and the film. In a second embodiment, Fig. 6, the containers are each provided with a tear strip 40, the opposing faces being sealed together to the right of the line 37 only.

Abstract: 1459641 Making hydraulic cylinders; extruding CATERPILLAR TRACTOR CO 12 March 1974 [12 March 1973] 11017/74 Headings B3P and B3A A method of making an hydraulic cylinder comprises cold forming a metallic blank into a hollow, generally cylindrical body 10 having a closed forward end defining a forward end wall 22 and an open rear end 16, wherein the end wall is formed with a substantially conical interior surface which is inclined at a first angle A to a perpendicular to the axis of the body 10 and forming an annular ridge 20 in the body intermediate the end wall and the cylinder bore defining a generally radially directed portion and a generally axially directed portion, the generally radially directed portion being formed at a second angle B to the axis. The cylinder is formed from a length of carbon steel bar stock which is first shot peened to remove scale and oxidation and then cleaned, pickled and rinsed. The cleaned blank is immersed in zinc phosphate at 185‹ F. for five minutes, rinsed in cold and then hot water and finally immersed in a soap bath solution at 185‹F. for five minutes. The blank is then coined in a press die so that it has a recess at one end and a protruding portion at the other, Fig. 3 (not shown). The preformed blank is placed in a press die, Fig. 10, and formed by backward extrusion into the cylinder 10, Fig. 4, which has an internally stepped portion 14 and a generally rectangular nose or tang 18. If necessary the cylinder 10 may be annealed and/or the cleaning and coating with lubricant steps repeated. The cylinder is next drawn or forward extruded to reduce the thickness of the cylinder wall 24, Fig. 11, and produce a tapered portion 26. A coining operation next forms a square end to the tang, Fig. 6 (not shown), and further drawing or forward extrusion steps bring the cylinder to its final dimensions. The bore is dimensionally adjusted by roll burnishing and ports 32, 34 are drilled and tapped in the cylinder wall while a hole 36 is drilled in the tang 18. A plurality of flats 46 is formed on the cylinder by machining or by drawing prior to roll burnishing. Finally a piston assembly 40 is inserted in the cylinder and an end cap 38 is screwed into the open end of the cylinder.

Abstract: 215,767. British Thomson-Houston Co., Ltd., (Assignees of Emmet, W. Le R.). May 8, 1923, [Convention date]. Stop-gear.-An electromagnet in a circuit controlled by speed-responsive means controls a servomotor operating the throttle-valve of a prime mover, and the speed is caused to fluctuate within predetermined narrow limits by means operated by the governor for holding contacts in the circuit definitely open or closed at one speed limit until the other speed limit is reached. A flexiblearmed centrifugal governor 44 engages a lever 35 to close a circuit 32 through contacts 30, 31 against the action of a spring 49. The electromagnet 25 is energized to open a valve 17 admitting fluid behind a piston 12 to open the throttle valve 10 against the action of a spring 14. As speed increases the contacts separate and the electromagnet is de-energized to close the valve 17 and open a fluid discharge valve 18. An electromagnet 29 ensures good contact until the governor breaks the circuit. As the load increases the tension of the spring 49 is increased by means of levers 50, 53 and link 52, causing the governor to function at a lower speed. The fluid used may be oil from the forced-feed lubricating system so that if the pressure falls the throttle valve will close.

Title: Improvements in manufacture of cellular-rubber or rubber-like material
IPC: C08J9/06
Filed: 1938-04-14
Abstract: Cellular rubber or artificial rubber in which substantially all the cells are closed is made by mixing a vulcanizable rubber mix with a material capable of generating an inflating gas under the influence of heat, heating the mix to develop the inflating gas while allowing the mass to expand against an exteriorly imposed gaseous counter pressure sufficient to restrain the inflating gas from rupturing the cells, reducing the gaseous counterpressure to permit further expansion of the mass, and then completing the vulcanization of the mass while it is confined under conditions preventing any substantial diffusion from the mass of the inflating gas for example in a closed mould.  The inflating gas may be nitrogen which may be generated by the interaction of sodium nitrite and ammonium acetate, carbon dioxide, carbon monoxide, methane, hydrogen sulphide, nitrous oxide, or mixtures thereof.  The same gas is preferably used both for inflation and counter pressure.  Supplementary gas-forming chemicals which yield additional inflating gas at the temperature of the final vulcanization may be included in the mix.
