Title: Improvements in means for starting electric discharge apparatus operating on oscillating circuit
IPC: H02M1/04
Filed: 1938-06-16
Abstract: 507,707. Converting. FORSSELL, H., and ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. June 16, 1938, No. 17940. [Class 38(ii)] In it self-excited inverter or frequency changer comprising grid-controlled electric discharge devices feeding an oscillatory circuit 1, 2 the inductance 1 of which may be the exciting winding of a furnace, starting is effected by temporarily connecting the grids and an inductance associated therewith to a D.C. source and suddenly breaking said connection so as to obtain reversal of the grid polarities and thus produce the necessary initial oscillation in the load circuit. Fig. 1 shows a frequency changer fed from a 3-phase source 38 in which two groups of grids 14, 15 associated with two anode groups are, in normal operation, fed from the oscillatory load circuit 1, 2 through a transformer 24 and phase-shifting circuit 22,23. The secondary of the transformer 24 also serves as the inductance for effecting reversal of grid polarity on breaking connection to a battery 20 temporarily switched in at starting by a switch 19. In a modification, Fig. 2 (not shown), in which the grids are normally energized through a circuit comprising opposed rectifiers and a D.C. source, the same D.C. source is utilized in association with the secondary winding of a transformer in the grid circuit to obtain the necessary initial reversal of grid polarity at starting. Fig. 3 shows an arrangement in which the oscillatory circuit 1, 2 is fed from a D.C. source 39 through an inverter 40 having a commutation anode 43. The D.C. source 35 is utilized in association with the secondary of transformer 28 in the manner above described for effecting initial reversal of the grid polarities by closing and opening the switch 45. This operation also energizes temporarily the closing coil 50 of a switch 53 which causes charging of a condenser 48 from a D.C. source 51 and establishes connections whereby the commutation anode 43 and its associated grid are brought into operation to effect commutation between the main anodes for the initial cycle of operation of the inverter. In all the arrangements, a resistance 11 is included in the load circuit during starting but may be switched out in normal running.

Title: Process for the treatment of waste gases
IPC: C01B7/19
Filed: 1963-05-08
Abstract: Hydrogen fluoride, in the form of a concentrated solution or a gas, is recovered from waste gases, such as those obtained from processes of acidulation and/or calcination of phosphatic materials, which contain minor amounts of fluorine values, silica values and suspended solid impurities, by adjusting the temperature of the gas, the water concentration and total fluorine concentration in the gas, so as to obtain a molar ratio of HF to SiF4 of at least 5 : 1, separating substantially all of the suspended <PICT:1046273/C1/1> reduction of the HF to SiF4 ratio obtained, and thereafter separating the fluorine values in the gas from the major portion thereof.  Such separation may be obtained by scrubbing the gas with an aqueous solution, and utilizing the sensible heat of the gas to form a concentrated solution of hydrogen fluoride, and recovering said solution.  The desired ratio of HF to SiF4 is preferably obtained by adjusting the temperature of the gas so that it is in excess of 300 DEG  F., preferably at least 800 DEG  F., adjusting the total fluorine concentration in the gas so that it is in excess of 0.05%, preferably at least 0.5%, by volume of the gas, and adjusting the water concentration in the gas so that it is within the range of 5 to 75%, preferably 20 to 30%, by volume of the gas.  The aqueous hydrogen fluoride obtained may be subjected to additional solid impurities from the gas, while permitting no variation in the adjusted temperature, water concentration and total fluorine concentration in the gas which would result in a substantial processing to obtain a gaseous hydrogen fluoride product.  Fig. 1 is a schematic representation of a flow process according to the invention to form a concentrated HF solution.  Gases which result from the chemical reaction in mixer 2 and storage chamber 3 are preferably burnt in combustion chamber 6 and are then mixed with the gases from kiln 5. The temperature, total fluorine concentration and water concentration of the gases are then adjusted, and the gases pass to electrostatic precipitator 11, where substantially all of the solid material is removed from the gas stream, and then to absorption tower 14 where the HF is separated from the major portion of the gas stream.  Figs. 2 and 3 (not shown) indicate flow systems for converting the concentrated HF solution to HF gas in a salable form.

Abstract: 1,022,183. Cable conduits; cable joints and terminations; electric transmission systems. BRITISH INSULATED CALLENDER'S CABLES Ltd. May 7, 1964 [May 8, 1963], No. 18252/63. Headings H2C, H2E and H2H. [Also in Division HI], In an electric power transmission system using a concentric cable, more than one separate concentric conductor is provided for some or all of the phases, and the allocation of the phases to the various conductors of differing radii is made so that they are systematically intermingled. As described, a three-phase cable (Fig. 1, not shown) comprises five conductors A1, A2 (phase 1), B (phase 2), C1, C2 (phase 3) with insulation between adjacent conductors and over the outermost, A2. The current-carrying capacity of conductor B is twice that of any other conductor. The mean radii a 1 , a 2 , b, c 1 , c 2  of conductors A1, A2, B, C 1 , C 2 , respectively, may be such that, substantially, a 1 a 2  = b<SP>2</SP> = c 1 c 2 . A central channel 1 is defined by a steel spiral 2 upon which copper wires 3 are laid up to form conductor A1. The insulation 5 is built up from lappings of transversely serrated polycarbonate tape, applied butting. Conductor C1 consists of copper wires, whilst conductor B consists of copper wires B1 overlaid with aluminium wires B2, and conductors C2, A2 consist of aluminium wires only. A perforated metal screen 6 is applied over the last layer of insulation and is followed by an open turn lapping 7 of non- ferrous D-section tape. This core is drawn into a steel pipe 8 having an anti-corrosive serving 9. The cable may be cooled by the evaporation of liquid refrigerant introduced into the channel 1, as described in Specification 988,030, when straight-through joints and terminations are made in sealed enclosures 12, 13, Fig. 2 (not shown), which communicate with refrigerating apparatus. Clamps 10 embrace each concentric conductor and connectors 11 are used either to make through connections or, at a termination, to join conductors of the same phase, when conducting stalks 14 continue through porcelain insulators 15 to provide terminals. In an alter. native, a three-phase cable comprises six conductors, each of the same current-carrying capacity, i.e., the conductor B, Fig. 1, may be considered as split into two concentric conductors with insulation between them. In another alternative, suitable for single-phase A.C. or for D.C., a triple-concentric cable is used.

Abstract: 929,515. Bearings. ROCKWELL-STANDARD CORPORATION. May 19, 1961 [May 20, 1960], No. 18295/61. Class 12 (3). [Also in Group XXXI] In a means for lubricating the bearings in a drive axle assembly, lubricant is transferred from an annular reservoir to a reservoir interposed between the bearings and from the latter reservoir to said bearings. In an embodiment the annular reservoir is defined by a hub 44, a carrier 94 and a plate 108 and the reservoir interposed between the bearings is a groove 160 in said hub 44. During the rotation of the hub 44, the lubricant is transferred from the annular reservoir to the groove 160. This is effected by an axial opening 170 in the hub 44 which, when in its lower position, dips into the lubricant in the annular reservoir and transfers a quantity to a recess 180 in the hub 44. When the opening 170 is in its upper position the lubricant empties from the recess 180 to the groove 160 via a cavity 162 and a channel 168 in the hub 44. The lubricant overflows from the groove 160 to lubricate the bearings 30, 40 and then returns to the annular reservoir.

Title: Electric relays for automatic voltage regulation
IPC: H02J3/42
Filed: 1924-08-05
Abstract: 242,002. Railing, A. H., and Angold, A. E. Aug. 5, 1924. Systems depending on two or more machines; regulation, automatic.-A device for switching a generator into circuit with an existing supply, when its voltage has been correctly adjusted, and for continuing the voltage regulation when the machine is running parallel, comprises two solenoids A, B controlled by the line and generator voltages respectively. The coils act in opposition and are arranged as shown in Fig. 1, or at opposite ends of a pivoted lever. Three contacts F1, F2, F3 at the end of the control lever are operated in turn to raise the machine voltage, to operate the parallelling switch, and to reduce the machine voltage if in excess. The upper contact F1 energizes one field in a reversible rheostat-controlling motor S to increase the machine voltage to the required value; at the instant the line core is overcome the contact F2 is made and the parallelling switch M, M1 is closed by means of the contactor T. A delay action is preferably incorporated, and should the difference in voltage be excessive the contact F3 is made before the switch M, M1 is closed and the paradlelling is deferred by the short circuiting of the contactor T until the voltage is reduced by the rheostat-controlling motor, which is reversed when either of the contacts F2 or F3 is made. When the switch M, M1 is closed the generator coil B only remains to control the rheostat, the line coil being cut out by an interlocked switch M2. By making the core of the line coil in two parts, which separate when the coil is de-energized, part of the weight opposing the generator coil is thereby relieved.
