Title: Improvements in or relating to electrodes for oxidising nitrogen
IPC: C01B21/20
Filed: 1919-12-31
Abstract: 159,709. Loring, F. H. Dec. 31, 1919. Gases, treating with electric discharge. - A continuous - current arc is repeatedly drawn out by reciprocating electrodes in a magnetic field. This field may be produced by a series coil 5 around the lower electrode or an external extension thereof, or within or surrounding the arc chamber, which may be of cast iron so as to form part of the magnetic circuit except when the coil surrounds it in which case brass or manganese steel may be used. The electrodes may be of magnetic or non - magnetic material. The replaceable lower electrode 6 may be fitted on a conical support 3, also renewable and held by a tapered socket 2. Alternatively, when the upper electrode is hollow, the upper part of the lower electrode may be cupped. When the coil is inside the chamber, electric connection may be made by means of a supplementary tapered sleeve with mica insulation between tapering surfaces. Air may pass through the hollow movable upper electrode 10 to the arcs, the usual inlets 11, 12 being closed. In a modification, the upper electrode socket passes through an insulating partition, above which it is slotted to admit air from the holes 11, 12. To facilitate ejection of the upper electrode from its holder 19 in the arrangement shown, a split sleeve 18 covering apertures in the holder can be slid on to the lower part of the holder. Products are withdrawn by a pump. Mica insulation such as 17, where used, should have a free surface of not less than 15 mm. in order to prevent arcing due to deposition of metallic dust. A section of the casing is removable and is held by plunger catches 22. A window 27 of amber-coloured mica is provided. The products may be employed for bleaching flour. Specification 22101/05 is referred to. According to the Provisional Specification, the magnetic field may be produced by bringing near the electrodes the poles of the usual series inductance, or connecting these poles by bridge-pieces to the lower electrodes.

Abstract: 197,353. Plauson's (Parent Co.), Ltd., (Plauson, H.). Dec. 7, 1921. Gases, separating mixtures of; diffusion apparatus for gases.- Vapours or gases are separated by selective passage through a porous diaphragm in an apparatus in which a difference of electric potential (about 20-100 volts) is maintained between the diaphragm and the vapours or gases by applying an electric charge either to the diaphragm or to the gases. The diaphragm may have fairly large pores and may be formed of loose powdered rnaterial such as sand, glass, carbon, graphite, carborundum, metal, china clay, silicic acid, cement, chalk, gypsum, feldspar &c. or of these materials treated to form a rigid diaphragm by addition of a binding agent, or 'by ignition, chemical decomposition, &c., or of superimposed slotted or corrugated metal plates; or wire netting between which porous material may be placed. Vapours generated by heating a liquid in the lower part 2, Fig. 1, of a still rise into contact with a porous diaphragm 3 clamped by insulated connections 5, 6 between the lower part 2 and the upper part 1. A perforated electrode 7 is arranged below the diaphragm and connected to the part 2. Electrical connections 15, 16 are made with the parts 1, 2. A diaphragm in the form of a number of connected porous cylinders and an electrode having arms-projecting into the cylinders may be used. Two diaphragms may be placed in series, and may be formed of loose material resting on-perforated plates in electrical connection with the parts of the still. The diaphragm may be cleaned during use by removing impurities which settle on its surface, as, for example, during the distillation of oils containing wax, naphthalene, anthracene, asphalt, &c. either by forming the diaphragm as a hollow rotary cylinder, against which a scraping knife or rotary cleaning brush is held, or as a hollow fixed cylinder containing a rotating cleaning-worm. The vapours generated in the still 2, Fig. 14, pass into the space between two diaphragms 3, 3<a>, one of which is charged positively and the other negatively, and the vapours which pass through each diaphragm are removed by separate, outlets 12, 12<a>. The apparatus may be used for the distillation of two liquids having about the same boiling- points but of different polarities. According to the Provisional Specification, the diaphragm may also be made of blood-charcoal or kieselguhr.

Title: A method of applying and maintaining pre-tension to the longitudinal reinforcement in pre-stressed concrete pipes
IPC: B28B21/60
Filed: 1953-11-27
Abstract: 732,037. Reinforced concrete. PAGET, R. C. May 6, 1954 [Nov. 27, 1953], No. 33048/53. Class 20 (4).  In a method of pretensioning longitudinal reinforcements for concrete pipes, shafts, or tunnels, and of maintaining such pre-tension until the reinforcements are bonded to the applied concrete, the reinforcements and mould parts are supported around a central shaft made in two parts which may be coupled axially by an interrupted thread connection. As shown, the two parts 7, 8 are connected by an interrupted . quick - release threaded joint 9 and carry fast and axially movable circular stress plates 10, 15 having equally spaced -tapered holes 12 to receive the reinforcing wires 13 and securing-wedges 14. The shaft 7, 8 is mounted in bearings 1, 2 supported on mountings 3, 4 fixed to a framework 5, 6, the part 5 being fixed and the part  6 being sufficiently separable therefrom to permit the removal of the finished pipe. A collapsible metal mould 17 is mounted coaxially upon the shaft between the stress plates, joint rings 19, 20, having holes 21 for the wires 13 to pass through being .fitted over the outer ends of the mould. A collar 22 is screwed onto the shaft 8 to bear against the plate 15 and is locked by a pin 24. A hydraulic jack 26, mounted in a thrust block 25, bears against the end of the shaft 8. A number of adjustable anchor bolts 27 are secured to the block 25 and to the plate 15, the turnbuckle portions 28 being removable by the withdrawal of clevis pins 29. The shaft 7 is provided with a pinion which engages through gears in a box 30 with a driving motor 31. To tension the wires 13 pressure is applied by the jack 26 to the end of the shaft 8, the plate 15 being anchored by the bolts 27 to the block 25, and the collar 22 is screwed up against the plate 15 and locked. by the pin 24, whereupon the pressure from the jack is released and the bolts 27 are unfastened from the .plate 15. The shaft is then rotated by the motor 31 while concrete 18 is cast upon the outer surface of the mould to cover the wires 13. After the concrete has hardened the thrust collar 22 is backed away from the plate 15 and the wires 13 are severed close to the outer surfaces of the rings 19, 20. The shaft joint 9 is subsequently disconnected and the part 6 of the framework is retracted, with the end of the shaft supported on the base by temporary cradling, and the shaft 8 similarly supported on the part 5. The pipe is now removed from the apparatus for application of the outer skin elsewhere. Specification 619,304, [Group XXVIII], is referred to.
Patent GB-601650-A (GB)
Title: Improvements in or relating to arrangements for selecting electric pulses of given width
IPC: G01R29/027
Filed: 1945-12-07
Abstract: 601,650. Pulse discriminating circuits. STANDARD TELEPHONES & CABLES, Ltd., and CHATTERJEA. P. K. Dec. 7, 1945, No. 33144. [Class 40 (vi)] In a pulse width discriminating circuit, the input pulse is applied to two energy storing devices, the energy of one device being employed to initiate an output pulse if the duration exceeds the lower limit t1, the energy of the other device being utilized to suppress the output pulse if the duration exceeds the upper limit t2. The potential across the capacitor 5, Fig. 1, rises gradually in response to a pulse applied over rectifier 3 and resistor 52, thyratron 6 firing if the pulse duration exceeds t1, to develop an output pulse across resistor 11. The pulse is delayed by network 12 for a period t2-t1 and then applied to valve 14. The capacitor 20 is charged similarly over rectifier 18 and resistor 53 and after a time t2 the potential is sufficiently great to prevent the pulse on the control grid of valve 14 from being effective, pulses of duration greater than t2 thus being suppressed. In a modification, Fig. 3 (not shown), the potential developed across capacitor 20 is applied to a similar pulse generator, the output pulse being combined in opposition with the pulse from the delay network 12. In a further modification, Fig. 4, rectifiers 33 and 34 are biassed to a non- conducting state from potential divider 43. An input pulse, delayed in network 42 for a time t2 is applied' to the rectifier 33 which is rendered conducting to transmit the pulse if it has a duration t1 or greater. The input pulse is applied to network 41 to delay it for a period t2-t1, and is then used to charge a capacitor 39, overcoming the bias on rectifier 33 after a further time t1. The pulse from rectifier 33 is applied to rectifier 34 and passes to the output unless the input pulse exceeds a duration t2, in which event the capacitor 40 will have charged to a potential overcoming the bias on rectifier 34 which then conducts.

Filed: 1968-07-11
Abstract: 1,193,575. Semi-conductor devices. MICROWAVE ASSOCIATES Inc. 11 July, 1968 [24 Nov., 1967], No. 33236/68. Heading H1K. A high-power microwave device comprises, on a substrate, a thin semi-conductor sheet 2, on which is a thin dielectric layer 3 carrying a mosaic pattern of narrow conducting stripes 4.. Two end regions 6 make contact to the semiconductor sheet. The structure is placed in a resonant cavity and in operation the semiconductor sheet is fed with D.C. so that carriers flow along it in a direction perpendicular to the stripes. An A.C. field will be set up between the stripes, arising from the noise components in the resonator, so that bunching of the carriers in the semi-conductor sheet will occur through interaction of these D.C. and A.C. fields. These bunches induce an alternating current in the stripes in inverse phase to the applied voltage thus delivering power to the external circuit via a coupler. The semi-conductor sheet may be composed of germanium, silicon, diamond, gallium arsenide, indium antimonide, gallium antimonide, indium arsenide, germanium telluride, or germanium sulphide. The device may also be used as an amplifier. It may be used in waveguides, cavity resonators, coaxial lines or slab transmission lines, and various stripe configurations may be employed, the stripes extending in the direction of the H.F. electric field of the A.C. wave.
