Filed: 1974-04-03
Abstract: 1458903 Reducing Ni-Co ores INCO Ltd 3 April 1974 [9 April 1973] 14795/74 Heading C7D  Particles of nickel or cobalt oxide, hydroxide, carbonate or nitrate containing 0.005 to 0.5% sulphur and one or more of the volatile impurities Sb, As, Bi, Pb, Se, S, Tl, Sn and Zn are reduced in a particulate bed by heating to a temperature high enough to reduce the starting material to metal form (e.g. above 800‹C) in a reducing atmosphere (e.g. CO or H 2 ) substantial agglomeration of the particles which undergo relative movement being prevented by the inclusion in the bed of CaO, MgO or a compound heat decomposable thereto (e.g. lime, limestone, magnesia, dolomite, magnesium chloride, magnesium sulphate, magnesium nitrate, calcium chloride, calcium nitrate or magnesium carbonate). The starting material may be obtained by roasting a sulphide or subsulphide (e.g. at 500- 1200‹C) and subsequently chlorinating prior to the reduction process which may be carried out in a rotary furnace or fluidized bed using natural gas, coal or oil and free oxygen containing gas as the fluidizing, heating and reducing medium. Sulphur may be added to the starting material e.g. in the form of sulphuric acid or as a sulphur bearing fuel gas and the additive may be added in the form of an aqueous solution alone or in conjunction with solid additive, the sulphur containing additive being removed from the reduced product by gaseous elutriation.

Abstract: 1338305 Testing multi-conductor cables WALTER ROSE KG 13 May 1971 [28 Oct 1970] 14817/71 Heading G1U In a method of identifying the conductors of a multi-conductor telephone cable, first a test signal of 185 c/s from an oscillator 0, Figs. 1 and 2, is applied via a transformer to two previously identified conductors which have been connected together at the receiving end of the cable, second either the current flowing, Fig. 1, or the voltage between the conductors, Fig. 2, is measured at both the transmitting and receiving ends of the cable, and thirdly one of the previously identified conductors is replaced by what is thought to be another conductor Rx and the currents or voltages remeasured, any significant decrease in current or voltage at the receiving end indicating that what was thought to be another conductor as not simply another conductor but two or more conductors connected in series via exchange equipment. In a modification, Fig. 3, the oscillator 0 is arranged so that it only oscillates when connected via the transformer to a load larger than 2k ohms, and with the previously identified conductors connected a potentiometer Pot is adjusted so that the oscillator is first not oscillating, so that when an unknown conductor is connected in place of one of the known conductors the oscillator will oscillate if the loop impedance is increased. In Fig. 3, the oscillator is also coupled to a radio transmitter Se so that the mechanic at the receiving end of the cable can be aprised of the fact that a non-conductor has been connected.

Abstract: 899,681. Rocket propulsion. BRISTOL SIDDELEY ENGINES Ltd. April 28, 1960 [May 1, 1959], No. 14883/59. Class 110 (3). [Also in Group XXIX] Apparatus for controlling the flow ratio of oxidant and of fuel to a combustion chamber, such as in a rocket motor, comprises flow pipes 3, 4 for leading oxidant and a fuel respectively to the combustion chamber, means 1, 2 in each pipe capable of producing a pressure difference in response to flow therethrough, separate pressure tappings leading from each of the flow paths at a position upstream of the means therein and at a position of reduced pressure produced by the means, a valve-actuating device 9 responsive differentially to the pressure difference for use by each of the means and a valve 7 operable by the valve-actuating device to vary the rate of flow through one of the pipes with respect to the flow through the other pipe, whereby the flow ratio can be maintained substantially constant, the valve-actuating device comprising a housing 12 defining a pair of separate compartments in which pistons 10, 11 are mounted, and a rod 8 connecting at least one of the pistons with the valve. The means 1, 2 as shown in Fig. 1, are in the form of Venturi meters, the opposite sides of the piston 10 being connected by pipes 15, 19 into the Venturi-meter 1, and opposite sides of the piston 11, being connected to the Venturi-meter 2 by a pipe 20 and a connection upstream of the latter meter. The pistons are connected by a common rod 8 which is coupled to a valve 7 located in the fuel pipe 4. In operation, if a variation in flow occurs in the oxidant pipe 3, the pressure difference thereby produced across the Venturi-meter 1 moves the piston 10 and thus adjusts the position of the valve in order to permit more or less fuel through the pipe 4. The flow through the Venturi 1 is initially set by a by-pass 5, 6; alternatively, Venturi-meter 2 may be provided with the by-pass. In a modification, the Venturi-meters, which have fixed throats, may be provided with a spring- loaded throttling device which produces a varying flow characteristic through the Venturi.

Filed: 1930-05-17
Abstract: 345,876. Steam turbines. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN, 17, Võstra Tradgardsgatan, Stockholm. May 17, 1930, No. 15199. Convention date, May 28, 1929. [Class 110 (iii).] In a turbine of the Ljungstr÷m type all the steam leaving the radial flow blade system is deviated in one direction only through an axial-flow blade system. Steam enters the turbine through conduits 6, 7, and passes by way of radial blades 5 through guide-blades 13 to the axial blade system 14. A portion of the steam passes through a water preheater 28 from a passage 27. Labyrinth packings 21, 22 form axial balancing systems. Steam supply conduits 23 .. 26 pass through the packings. In a modified arrangement the axial blade system consists of one moving ring only attached to a disc 16, fixed guide-blades being dispensed with. Bent guide-plates situated between the radial and axial systems prevent eddies and appreciable expansion in the steam. Steam leaking through axial packings 17, 18 is led back to the turbine under control of a valve one side of which is acted upon by atmospheric pressure. In a further construction guide blades are dispensed with between the radial flow and axial flow systems. The outer radial blade ring 10 rotates in the opposite direction to the single axial blade ring. Extra steam, which may come from a steam accumulator, is supplied through a conduit situated on the side of the radial-flow system opposite to the axial flow blade disc. The conduit is attached to an external conduit by a flexible pipe connection. Fig. 4 illustrates a turbine wherein the last two blade rings 10, 44 of the radial flow system are connected to blade rings 45, 46 respectively of the axial flow system. A fixed guide-blade ring 47 separates the two systems. Conduits 23 .. 26, Fig. 1, may be used for extracting steam.
