Title: Improvements in sliver balling machines and yarn and like winding machines
IPC: B65H54/42
Filed: 1937-03-17
Abstract: 493,945. Sliver balling-apparatus ; winding yarns. FRASER, G. S., and FRASER, N., and FRASER, (nÚe SCOTT), J. J., FRASER, G. S., and KYD, J. A., [Representatives of FRASER, J.]. March 17, 1937, No. 7786. [Classes 120 (i) and 120 (ii)] In a sliver-balling or a yarn or like winding machine in which the ball or package is wound by frictional contact with a driving roller, the package being wound is sustained during the winding operation by a bifurcated pivoted lever structure the arms of which embrace stationary end plates which shroud only the nip of the driving roller with the package and part of the end surfaces thereof. As shown the ball 1 is wound on a boss 4 mounted on an arbor 5 having non-rotatable trunnions 6 supported in bayonet slots 7a in a counterweighted bifurcated lever 8, the arms of which embrace the two stationary end plates 3 fixed to the machine frame and maintained parallel with one another by a bar 3b connecting the out-turned end portions 3a ; pads 8b on the arms of the lever 8 project through holes therein and slide against the outer surfaces of the extensions 3c of the plates as the ball is wound. The arbor 5 or the ball formed thereon is caused to press against the driving roller 2 by a friction band 10 wrapped about a drum 11 on the pivot 9 of the lever ; one end of the band is connected to a rod 30 guided in a lug 31 on the frame and tensioned by an adjustable spring 29 and the other end is pivoted to the upper arm 26 of a pivoted lever, the lower arm 25 of which carries a cam follower 24 engaging a cam 39 on a rock-shaft 38 which also carries a lever 22 connected by a pin- and-slot with the arm 19 of a pedal lever 13 carried on a pivot 18. When the package attains its full diameter, the counterweight 8a, contacts with an adjustable stop 34 carried by a shaft 36 and rocks the shaft to stop the machine ; the friction band 10 is then released by elevating the pedal lever 13 and the lever 8 is lowered by moving the handle 17 until the completed package contacts with an inclined plate 14 when the trunnions 6 move out of the slots 7 and the package rolls down the plate 14, The lever 8 then moves up under the action of the counterweight 8a and the band 10 is re-engaged with the drum 11 by depressing the pedal lever 13. The lever 8 carries rubber pads 37 which rub on the end faces of the boss 4 and prevent stray fibres becoming wound around the trunnions 6. When a cross-wound roll is formed a reciprocatory guide is disposed between the driving roller 2 and delivery roller 2a. According to the Provisional Specification the winding apparatus may be applied to a card when the driving roller 2 is preferably disposed below the boss 4 and extension plates may be fitted to the end plates 3 to guide the sliver when starting up and in a yarn-winding machine the end plate may be adjustable for different widths of package.

Title: Improvements in or relating to the treatment for transport and/or utilisation of bituminous and like materials
IPC: C10C3/08
Filed: 1926-03-20
Abstract: 274,540. Testrup, N., Boberg, T., and Techno-Chemical Laboratories, Ltd. March 20, 1926. Asphalts. - Bituminous materials such as Trinidad asphalt are melted and freed from water, a substantially equal weight; of a vapourizable solvent is added, insoluble matter is allowed to settle out, and the solvent is recovered. The amount of solvent is sufficient to maintain the mixture in a liquid condition at ordinary temperature. The invention facilitates the transport and storage of asphalt, which may be pumped into tank steamers for transport before removing the solvent, or may be melted and pumped after such removal, the material being again melted for example by steam pipes in the hold of the steamer, and pumped out at its destination. Molten asphalt is led by pipes A, A<2>, to a chamber A<3> where it mixes with a solvent such as a high-boiling petrol fraction led by a pipe B from the sand washer K<1>, and from the condensers N<1> and C<1>. The solution flows by the pipes E to a settling tank E<1> provided with a baffle E<2>, where the sand &c. settles and is withdrawn by a conveyer K<1>. The dilute solution passes to a condenser F<1>, solvent passing into the condenser C<1>, and the concentrated solution to the condenser G<1>, where the last traces of solvent are removed by steam from the condenser C<1> which has been passed through a superheater R, the purified bitumen being withdrawn by the pipe H. The sand &c. in the conveyer K<1> meets a stream of solvent which enters by the pipe I, and leaves by the pipe K<2>, to remove adhering asphalt. Before being discharged, the sand passes through a separator M', where a current of steam removes the last traces of solvent.

Title: Improvements in or relating to Super-Conductors
IPC: H01L39/06
Filed: 1967-02-17
Abstract: 1179896 Super-conductors SIEMENS AG 17 Feb 1967 [18 Feb 1966] 7806/67 Headings H1A and A4D A composite conductor comprises a superconductor coated with a "normally" conducting metal, the surface being covered with aluminium oxide or beryllium oxide. The oxide layer may be on the surface of an aluminium or beryllium (preferably high purity) layer or strip, the metallic aluminium or beryllium then being in contact with the super-conductor to provide a shunt resistance and thermal conductor which reduces the current degradation effect and absorbs energy when the super-conductor switches to normal. Additional layers of copper, silver or gold may also be used for this purpose. Fig. 3 shows a cable comprising a plurality of super-conductor wires 31 with a metal coating 32 of normal metal such as copper, silver or gold. The interstices 33 are filled with a good conducting metal such as indium, gallium, lead, or alloys of lead-bismuth or tin-indium. The assembly is surrounded by a lapped tape 34 of aluminium with an aluminium oxide outer layer 35. The super-conductor may consist of niobiumzirconium alloy, Nb 3 Sn, V3Ga, or a niobiumtitanium alloy. A multi-layer coil construction with intervening layers of aluminium, with or without oxide layers, is also described, and another embodiment consists of a bundle of tapes sandwiched together. Methods of applying the aluminium or beryllium coating by electro-deposition using organo-aluminium baths (many examples given) are described in detail; the coated conductors may then be drawn or pressed and tempered. The oxide layer may be produced by an oxalic or sulphuric acid oxidizing bath, followed by heating to provide "sealing"; pores may also be filled with pigment or insulating lacquer.
