Title: A method of producing a copper base alloy conductor
IPC: C22C9/00
Filed: 1963-06-13
Abstract: A conductor having high electrical conductivity and strength at elevated temperatures is produced by forming a workpiece of an alloy consisting of 0.01 to 0.15% Zr and balance refined Cu, and passing the workpiece through a furnace, first through a higher temperature heating zone e.g. at between 1350 and 1550 DEG F. having a reducing atmosphere e.g. of cracked ammonia (75% H2, 25% N2, by volume) and next through a lower temperature cooling zone e.g. at between 150 and 250 DEG F. having a reducing atmosphere e.g. H2, to solution anneal and partially age it. The annealed workpiece may be cold worked in a suitable confining die without prior additional age hardening to form a semi-conductor mount (see Division H1).
Patent GB-682356-A (GB)
IPC: C03B5/12
Filed: 1950-09-26
Abstract: 682,356. Glass manufacture. METALLGES. AKT.-GES. Sept. 26, 1950 [Oct. 31, 1949; Oct. 31, 1949], No. 23601/50. Class 56. Mixtures of initial materials for use in the production of glass are prepared by mixing the constituents consisting substantially of quartz, soda, and lime with waste glass material and solid fuel, granulating and sintering the granulated mixture disposed in a layer on a gaspermeable grate by passing air through the layer in accordance with the suction draught sintering process to form a separate intermediate product adapted to be subsequently melted in a glass melting furnace. Alternatively the constituents and waste glass without fuel may be mixed, granulated, and sintered, whilst disposed on the gas-permeable base of a sintering apparatus, by the passage therethrough of hot gases, for example the hot waste gases of glass furnaces. Advantageously calcium carbonate is replaced by quicklime or calcium hydrate, and the coke fuel is moistened and powdered with calcium oxide before being mixed with the granulated constituents. The permeability of the charge to gas during the sintering process is further ensured by adding 1-4 per cent, preferably 2 per cent, of wood flour, which burns at a low temperature leaving cavities. Additions such as arsenic, ZnO, CeO 2 , CaSO 4  e.g. as gypsum or anhydrite, or other alkaline earth sulphates may also be made, such additions may be made during sintering and are not too finely ground. Sodium sulphate or alkali chlorides may be used instead of soda. The fuels preferably have low ash and iron contents, and the SiO 2 , CaO, Al 2 O 3 , and MgO in the coke ash may be taken into account in compounding the mixture. Burnt limestone may be used as a quicklime, or lime sludge or calcined dolomite may be used. 10-50 per cent by weight of glass waste, cullet, or glass fragments disintegrated to particles below 5 mms. may be used as waste or return material to be added to the initial constituents. The grate of the sintering apparatus is advantageously first covered with a layer of presintered material. Granular quartz of maximum particle size of 1 to 2 mms. is a suitable source of SiO 2 . A short intermediate furnace, e.g. a rotary tube furnace traversed by part of the incandescent gases of the tank furnace with air added to maintain the oxidising condition of the gases, may be interposed between the sintering apparatus and the melting tank to preheat the sinter, re-oxidise any reduced iron oxide, and to burn out the final carbon residues. Advantageously hot gases having a low sulphur content are used for the sintering, and care is taken e.g. by adding sufficient air to the hot combustion gases to ensure the complete combustion of any sulphur obtained as sulphide during the reaction of the components.

Title: Improvements in or relating to the control of variable attenuation networks for alternating current signalling or like systems
IPC: H04B3/20
Filed: 1934-08-18
Abstract: 442,947. Transmission systems. TELEPHONE MANUFACTURING CO., Ltd., Martell Road, West Dulwich, London, and BURRIDGE, B. J., 1, Highview Avenue, Wallington, Surrey. Aug. 18, 1934, No. 23889. [Class 40 (iv)] Variable attenuation networks controlled by varying the direct current flowing therethrough are conductively connected in a multi-branch or bridge circuit to which a source of D.C. is applied for determining the normal condition of the network and the branches of which comprise resistances or two-terminal (diode or metal) rectifiers, the variation in D.C. for control purposes being obtained over conductive connections to one or more of the branches. The control may be manual or by rectified alternating signal current from one or more channels. Fig 4 shows an arrangement for controlling four networks by the application of a control voltage to one of the arms of a multibranch circuit R1 ... R7 the terminals of which are suitably connected to a D.C. source to determine the initial biassing currents. In another arrangement, Fig. 6, using a simple bridge circuit each of one pair of bridge arms consists of a pair of rectifiers and these, in the case of one arm, take part in a voltage doubler rectifying circuit to which an alternating control current is applied. The invention is shown in its application to an echo suppressing arrangement in a repeater, Fig. 7 (not shown). In a further application, Fig. 8, to the control of two loud-speaker circuits, four networks MS1, C1, MS2, C2, connected in series are controlled by a bridge circuit the junction points of the networks being connected to a D.C. source and ground to provide normal biassing currents. The networks MS1, MS2 control the transmission paths whereas C1, C2 control the control paths. In Fig. 1 two output circuits of a triode are made effective one at a time by manual control at SW of one of the arms of the bridge. Fig. 2 shows the application of the invention to a system in which the substations of a telephone system can be effectively connected at the will of an important official to a common circuit L to which the official is connected. This system forms the subject-matter of Specification 443,011. Normally, the connections between the substations and the common line are blocked at the networks CN1-CN3, the normal telephone channels IN1-IN3 to the substations being effective over networks N1-N3. By means of key SW3 or selector SW4 respectively all or any of the networks CN1-CN3 may be conditioned for speech between the substations and the common line, the corresponding networks N1-N3 being simultaneously blocked. In the further arrangement shown in Fig. 3 a network N1 in the output circuit of a diode-triode is controlled by application to bridge arm R3 of control voltage derived from the diode portion of the valve.

Title: Animal-restraining devices
IPC: A61D3/00
Filed: 1972-05-25
Abstract: 1381022 Constraining animals W B GAUNTLETT 21 May 1973 [25 May 1972] 24554/72 Heading AIM [Also in Division A5] An animal restraining device comprises an upright support frame 2, an animal head restraining member 4 connected to each of the opposite sides of the frame 2 so as to be movable simultaneously from an inoperative position adjacent the sides to an operative position inwards from the sides and means for moving the members 4 from the inoperative to the operative position. As shown in Fig. 1, the frame 2 is held upright at the end of a cattle race 3, which comprises parallel fences forming a corridor leading from a yard. The members 4 are connected to the sides 5 of the frame by links 7 pivoted at 8, 9 and at their upper ends to a yoke 11 by links 10 pivoted at 12, 13. A guide rod 14 extending upwardly from yoke 11 is guided in a tubular guide member 15 mounted on frame 2, and is connected by a rope passing over pulleys to a lever with a pawl-and-ratchet mechanism. In operation, the yoke 11 is raised by actuation of lever, so that the head restraining members 4 are raised and separated. An animal moving along the race 3 is trapped by the neck when it reaches the end by operation of the lever to raise the head restraining members 4 and to make them approach each other. The animal is then held so that various operations may be performed, e.g. branding, ear-punching, milking, washing, administering of medicine, castrating, artificial insemination, pregnancy diagnosis, drenching, weighing; T.B. testing. The device is suitable for use with animals of different sizes, since by varying the movement of lever 30, the distance between the members 4 may be varied. Instead of the lever there may be electrical or hydraulic actuating means operated by a pedal, or a pedal-operated switch or fluid control valve. The members 4 may be moved automatically, e.g. by the animal itself, which may interrupt a light-beam directed to a photo-electric cell, or step on a pressure-operated switch. Drenching or similar equipment may be operated by such automatic means.
