Title: Methods of producing ductile superconductive alloys
IPC: C22C1/04
Filed: 1974-09-18
Abstract: 1473334 Superconductors BATTELLEINSTITUT eV 18 Sept 1974 [21 Sept 1973] 40710/74 Heading H1A [Also in Division C7] A method of producing a ductile superconductive alloy comprises forming a melt of constituents which combine to form a superconductive compound having the #-W(A15) structure and base metal and solidifying by cooling at a rate of at least 1000 C. per second, preferably 5 Î 10<SP>4</SP> to 1 x 10<SP>6</SP> C. per second. The fast cooling rate achieves such a state of dispersion of the superconductive compound that the critical distance for the tunnel effect is not attained. It is stated that alloys containing less superconductive compound than is usually required may be made by the method, and also that superconductive alloys may be prepared from intermetallic compounds, e.g. V 3 Al, not usually exhibiting superconductive properties. Cooling at the required rate may be effected by dispersion into an argon atmosphere, optionally on to cooled plates. The granules obtained are compacted and extruded, cast or rolled, with soft-annealing, into desired shapes. Alloy systems specified have copper, silver or gold as the base metal and intermetallic compounds of niobium or vanadium with tin, aluminium, silicon, gallium or germanium as the superconductive compound. The proportions of alloy constituents are selected to correspond to the quasi-binary section of the ternary system. In the case of the gold-vanadium-silicon system, the alloy is clad with gold before rolling.

Title: Improved electromagnetic receiver
IPC: H04R13/00
Filed: 1960-12-02
Abstract: 905,968. Receivers. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORPORATION. Dec. 2, 1960 [June 8, 1960], No. 41621/60. Class 40 (4). In a telephone receiver the armature 1 (Fig. 13) is secured on the concave side of a non- magnetic frusto-conical diaphragm 10, the convex side of which is adjacent the outer pole 2 of the magnetic system. The armature 1 which is in the form of a circular disc (Fig. 11) is retained by extrusions 16 formed on the diaphragm 10. This construction allows the air gap to be reduced while maintaining the magnetic gap constant. The Specification discusses the design of a receiver to achieve the maximum sensitivity consistent with stability and shows that this construction leads to high sensitivity as the mass of the armature may be reduced compared with that of a conventional receiver.

Title: Vacuum type load handling machanism
Inventor: OLSON JOHN ELMER
IPC: B66F9/18
Filed: 1964-10-14
Abstract: 1,083,187. Suction lifting devices; masted lift trucks. HYSTER CO. Oct. 14, 1964, No. 41906/64. Heading B8H. A bellows B, Fig. 1, of a vacuum lifting device, which may be mounted on a masted lift truck 11, is stabilized against lateral forces by pivoted links 41a, 41b, 41c, Fig. 5, and 43a, 43b, 43c, which extend between upper and lower plates 25, 32 and an intermediate plate 45. The lower plate carries a sealing lip 33 and a central sealing ring 37 which seals the central hole in a roll of paper R, Fig, 1. The pressure in the bellows is maintained below atmospheric and a load may be engaged by lowering the truck carriage 21, Fig. 1, or by allowing the bellows to expand slightly by admitting air. Air is supplied to the head 34 through a conduit 67, 69, 71, Fig. 5, without raising the bellows pressure. The head itself has contact pads 63, Fig. 9, and a mesh screen 61. The head 34<SP>1</SP>, Fig. 13, may be lowered by admitting air to the bellows through a valve 115 by closing a switch 135. When the head has engaged the load it is connected with a suction pump P and the interior of the bellows by closing a switch 137 to move a valve 101 from a seat 103 to a seat 105. This will also cause the bellows to contract and raise the load. The valve 101 is moved back on to the seat 103, thus allowing air to pass through conduit 91, when the load is to be released. Fig. 13A shows a valve 145 which is raised when a member 201 abuts a load to apply suction automatically to the head 34. Fig. 14 shows a lifting device 131 suspended from a monorail 121. The bellows has a sealing strip 133 but no bottom plate. A housing 129 encloses a vacuum pump 137 driven by a motor 139 and supports a lever 143 which controls suction. A control system such as the one shown in Fig. 13 may be provided. In Fig. 16 a valve 155 closes a suction conduit 157 when an end plate 151 rises. Fig. 17 shows a lifting device supported by a winch 173. When the device is lowered on to a load air is forced out of the bellows 179 through a check-valve 181 so that when the bellows are lifted the valve 181 closes and sufficient suction develops to lift the load. A manually operated valve may replace the check-valve.

Title: Improvements in and relating to the treatment of the residues of coal tars
Inventor: THOMAS BRIAN EDWARD ALSTON
IPC: C10C1/00
Filed: 1959-12-10
Abstract: Soft pitch, suitable for use as a binder for solid fuel briquettes or carbon electrodes, is produced by heating coal tar in a still or stills so that the volatile oils are vaporized, separating a heavy oil fraction boiling at 300 DEG C. or above from the volatile oils, recycling this heavy fraction to the still in which it was first removed from the coal tar, and withdrawing the required pitch product from the same still.  Crude tar is fed through conduit 51 into column 52 where it mixes with hot pitch flowing down over baffles 53, and water and some oils are volatilized from the tar.  The mixture of tar and pitch, reaching the base of the column, is pumped through conduit 54 to a coil 56 which is heated by hot gases from a fuelcombustion chamber 58. The heated tar and <PICT:0905775/III/1> pitch mixture next flows through conduit 60 into the upper chamber of column 52, where the heavier oil vapours flash off, and are led through conduit 61 to fractionating column 62.  All, or a portion of, the heavy oil, drawn off from the base of column 62, is pumped through conduit 65 to the upper chamber of column 52, where it mixes with the pitch residue of the tar after the vapours have been flashed off.  The mixture of pitch and heavy oil is collected in chamber 68 from which some of it is withdrawn as product via seal-pot 70, and the remainder overflows to the base of column 52. Specification 472,541 is referred to.

A variable capacitance circuit comprises a varactor diode 4 and resistors 3, 12 forming a phase splitting network connected between the collector, base and emitter of a transistor, capacitors 5, 6 isolating transistor D.C. operating voltages from the capacitor diode 4, and variable D.C. voltages are applied to both the diode 4 and transistor base to vary the transistor capacitance shunting the inductor 1 of a tuned circuit. To this end push-buttons or other switches 18, 19 may introduce voltage dividing resistors 11, 15 across the resistor 12 to vary the transistor bias, and similar switches 16, 17 may adjust the back bias and hence capacity of the diode 4. Alternatively the switches may be omitted and the voltages adjusted by varying the resistors 11, 15, and resistors 10, 14 in series with the capacitor diode 4. In this case the transistor and capacitor bias may be adjusted independently or in unison by ganging the resistors in pairs, and a pair of such ganged resistors may be located in a remote tuning -control unit of a radio or television receiver.

Title: Apparatus for contacting a gas with a liquid
IPC: C22B9/05
Filed: 1965-10-05
Abstract: An apparatus for contacting a gas with a fine spray of liquid which includes a rotating helical screw lift (see Division B1) is used in the disproportionation of aluminium mono-halide by molten aluminium stage and also in the condensing of the tri-halide to prevent build up of foreign gases in the system.ALSO:In an apparatus for contacting a gas with a fine spray of liquid droplets a screw lift comprising a rotatable vertical shaft carrying a peripheral helical formation lifts the liquid from a liquid space at the bottom of a chamber and projects it laterally as a spray into the gas space where it meets counter-current and/or transversely a gas stream flowing through the chamber.  The screw lift has a concave member behind it to block projection of the spray concurrent with the gas flow and is positioned adjacent to the outlet passage for the gas stream.  The concave member may conform to about 135 DEG  of the surface of the screw lift and two such lifts may be positioned at either side of the gas outlet passage having helical formations of opposite hand and rotating in opposite directions.  The helical formation of the screw lift may be a trough which decreases in depth as it ascends the rotating shaft.  The invention is exemplified by it use in the sub-halide distillation of aluminium (see Division C7).
