Title: Superconductive materials and devices
IPC: H01F6/00
Filed: 1963-09-19
Abstract: 1059123 Super-conductive devices WESTERN ELECTRIC CO Inc 19 Sept 1963 [25 Sept 1962] 36876/63 Headings H1A A5 and A4D A super-conductive device comprises a material having a negative internal field, means for applying thereto a magnetic field opposing the negative internal field and means for maintaining the material below its transition temperature. Such materials normally exhibit finite resistance at cryogenic temperatures, because of the field due to localized magnetic electrons, but become superconducting when an external magnetic field within a predetermined range is applied to neutralize the internal field. Particularly suitable are alloys of the form AB 2  where A is an element having an atomic number from 57 to 71 or from 89 to 92 and B is a super-conducting element such as Os, Al, Ir, Ru. Tables of suitable temperatures and applied external fields are given for A=Gd. Tb, Dy, Ho, Er, Tm, Yb, and B=Os or Ru. An  embodiment suitable for building up a large magnetic field comprises a set of concentric coils 30, 31, 32, 33. The first of these is an ordinary superconductor such as Nb 3 , Sn, which is fed with current of such value that the resulting field of 100 Kgauss is within the critical field of coil 30, and which brings coil 31 (TmOs2) into its superconducting range. This is then fed with current to provide a field of 150 Kgauss which brings coil 32 (ErOs 2 ) into the super-conducting range. This is in turn fed with current to produce a field of 200 Kgauss, whereupon coil 33 (HoOs 2 ) becomes super-conducting and is fed with current to provide an ultimate field of 250 Kgauss. Under suitable conditions the super-conductive conditions may be self-sustaining the field produced by the current keeping the coil in the super-conducting state. The super-conductors may be linear instead of coiled, e.g. when used in a cryotron switching device.

Title: Improvements in and relating to submersible systems for converting liquid monofuel into gas
IPC: F02M21/00
Filed: 1964-09-15
Abstract: 1,134,821. Controlling submarine vessels. G. H. PARKES. 14 Dec., 1965 [15 Sept., 1964], No. 37578/64. Headings B7A and B7V. [Also in Divisions F1 and F4] A submarine vessel includes a system for converting liquid monofuel into a gas (see Division F1), which gas is used to remove water from at least one ballast tank 76 of the submarine vessel. The gas is produced in a combustion chamber 70, the combustion space of which is exposed via an open-ended standpipe 7 to the pressure of the surrounding water in which the submarine vessel is submerged. Thus when the submarine vessel is at a depth of say 500 feet or more, the water pressure is sufficient to initiate decomposition of the monofuel ; the necessary temperature for the decomposition being produced by an electrical heating element 19. Gas is delivered to the ballast tank through a pipe 8. Gas can be released from the ballast tank by a valve 79. The mass of gas produced in the combustion chamber and thereby the mass of gas delivered to the ballast tank can be controlled by controlling the speed of a pump 39 which supplies the monofuel to the combustion chamber. By so controlling the production of the gas, the rate of descent of the submarine vessel can be adjusted to any constant value. The pump speed is controlled by a rheostat 85 which is associated with a suitably calibrated indicator dial (not shown). A valve 12 may be closed by a solenoid 11 to cause the gas to be delivered from the combustion chamber to a piston and cylinder assembly 15, 16, e.g. for operating the claws of a mechanical grab or for extending a telescopic boom.

In an example acrylonitrile fibres, a copolymer containing 98 mol per cent acrylonitrile and 2 mol per cent methacrylic acid are heated at a fixed length from 180‹ to 240‹ C. in air, then further heated at a rate of temperature elevation of 3‹ C. per min. under a contraction of 2% in air in a temperature range of from 240‹ to 280‹ C. The fibres were then passed through a 5% aqueous solution of sodium dithionite (pH=8) washed with water and then heated up to 1200‹ C. to carbonize the fibres. Graphitization may be achieved at temperatures up to 3500‹ C.

Abstract: 1,017,332. Rolling. ENGLISH ELECTRIC CO. Ltd. Jan. 25, 1963 [Oct. 26, 1961], No. 38440/61. Heading B3M. An electric control apparatus for controlling a reversing strip rolling mill installation having a strip rolling mill and two associated coilers on each side of the mill for carrying the strip, includes control means for automatically causing the installation to be stopped at the ends of successive rolling passes with the coilers in different angular positions such that the quality of strip rolled during successive passes becomes progressively smaller with each pass. Coilers 10 driven by motors 13 are situated on each side of a mill 12, the motors being connected through ratchet mechanisms 16 to slow-down units 15. Each slow-down unit counts the number of revolutions of its associated coiler during coiling and slows down and stops the coiler and mill after the same numbers of revolutions during the next uncoiling step. But since each ratchet mechanism 16, before the coiling starts, causes the drive from the motor 13 to the unit 15 to slip a fraction of a revolution, the unit counts very slightly fewer revolutions at each successive rolling pass. The final form of the rolled strip (Fig. 3, not shown), indicates the centre section of the strip near the mill 12 being thinner than the strip ends. The ratchet mechanism shown slips 120 degrees.
