Title: Improvements in distribution connected with single phase alternating current systems
IPC: H02J3/04
Filed: 1919-09-26
Abstract: 161,602. Taylor, A. M. Sept. 26, 1919. Systems depending on the use of static transformers.-Three-phase current is supplied over the three feeders I.P.C., Fig. 1, of a single-phase supply system by connecting the central cores of the feeders to the outer ends of a transformer S.U.T. and the outer conductors of the feeders to the inner ends of the transformer. In the modification shown in Fig. 2 the three-phase current is converted to twophase current before transmission and the singlephase generator A is connected to the central ceres of the feeders I.P.C. through a static balancer SSB. In a further modification shown in Fig. 3 the feeders I.P.C. are cut and the central cores connected to the single-phase generator A and to one end of two step-up transformers S.U.T., the other ends of these transformers being connected to the outer conductors of the feeders. The two-phase generator AA may be replaced by a three-phase generator and a Scott connection transformer employed. Specification 151,294 is referred to.

Title: Improvements in the electric arc treatment of vapourised carbonaceous materials
IPC: C01C3/02
Filed: 1931-08-24
Abstract: <PICT:0382690/IV/1> In the treatment of gaseous or vaporized carbonaceous materials, or gaseous suspensions of liquid or solid carbonaceous materials in the electric arc in order to obtain acetylene or other unsaturated hydrocarbons, inert finely-divided solid substances, such as sand or ashes, are suspended in the said materials and the resulting suspension is passed through the arc. The solid substances come into contact with the surfaces confining the arc space and prevent deposits forming thereon.  The introduction of the finely-divided inert solids may be continuous or intermittent and they may be mixed with the whole or a part of the gas to be treated, with inert gases or with active gases such as oxygen or steam.  The speed of flow of the gases may be increased during the introduction to increase the abrading action of the particles. The solid particles may also be introduced into the reaction chamber by means of a worm conveyer.  The solid particles may be removed from the reaction products in known manner.  As shown, carbonaceous gas enters through a pipe 1 and the electric arc passes between an electrode 5 and an externally water-cooled electrode 4.  Additional gas carrying sand is introduced through a pipe 2 and enters the arc furnace through a slot 8.ALSO:<PICT:0382690/III/1> In the treatment of gaseous or vaporized carbonaceous materials, or gaseous suspensions of liquid or solid carbonaceous materials in the electric arc, inert finely divided solid substances, such as sand or ashes, are suspended in the said materials and the resulting suspension is passed through the arc.

Title: Improvements in systems for the telephonic distribution of news, amusement and the like
IPC: H04H20/84
Filed: 1922-09-01
Abstract: 192,359. Western Electric Co., Ltd., (Assignees of Espenschied, L.). Jan. 25, 1922, [Convention date]. Systems for transmitting music, news, &c.- Amusement is broadcasted from a main distributing station by means of carrier currents superposed on telephone, power or other lines, with amplifying, filtering and rectifying arrangements. Fig. 1 shows the lay-out for such a system with three collecting stations 1, 2, 3 in communication with a main station M which distributes to subscribers through central stations A - - E, amplifiers A1, Aa, &c. being provided at all the stations. Transmission takes place at the collecting stations 1, 2, 3, Fig. 2, at suitable frequencies, and carrier current is supplied either at the collecting station or at the main station from sources S1, S2, S3, with modulators M2, M3, or the transmitter T1 may modulate the carrier current. The incoming carrier currents after amplification are superposed selectively by means of band filters F1, F2, F3 on an outgoing bus 13, which connects to existing lines La, Lb, Lc, Lc to central stations by means of a combination of high-pass and low-pass filters, and directly to subscribers' lines, such as 12. Wireless transmission may also be employed in place of any of these lines. The lines La, &c. are connected inductively at the central stations to a large number of subscribers' lines, condensers being provided to short-circuit the carrier currents with respect to the line jacks. At the substation, the circuit for a loud speaker 26, Fig. 4, is bridged across the line and is tuned by means of a condenser 21 and a variable transformer 22. The selective circuit may be loosely coupled through the transformer to a second tuned circuit containing a condenser 23, across the terminals of which is a detector 25 connected to the loud speaker. An anti-resonant circuit 27 prevents the carrier current reaching the telephone set, or the set may be of the anti-side tone type, the transmitter and receiver being conjugate. Fig. 8 shows the application to an alternating-current power circuit, including a step-down transformer 37, across which are bridged condensers 43, 44 to provide a path for the carrier current. The receiving circuit is bridged across the power circuit, and includes band filters BF1, BF2, BF3 for selecting a desired frequency. The filament and plate currents for a vacuum tube detector 41 may be supplied from the power circuit through a transformer 42 and vacuum tube rectifiers. Carrier current may be used for auxiliary functions such as the switching on and off of motors.

Abstract: 317,236. Clark, D'A. M., (Bendix Brake Co.). Aug. 22, 1928. Brakes.-In electric spot welding the webs to the rims of brake shoes by an apparatus of the type comprising separable means for clamping the work while a number of welds are effected, one of the clamps having a shaped working surface and carrying a series of electrodes cooperating with a separate, electrode, one electrode engages the web in which the rib is assembled and the rim is engaged by a series of arcuately arranged electrodes, energized in turn through circuit controlling means, a carriage controlling the current being movable angularly about the centre of curvature of the brake shoe. The web 20 is clamped between a block 40 insulated from the base 28 and a block 44 by screws 46 passing through a fixed yoke 48. The block 40 is slidable in a groove in a metal bar 52 seated in the insulator 42 to facilitate removal of the work. The rim 22, which is slotted to engage lugs on the web, is clamped by the block 40 by means of a cam 56 and insulated thrust plate 54, against a curved insulating member 34 facing an arcuate block 32, which is insulated from the base. This block 32 has a series of radial holes to receive electrodes 36, preferably with renewable lips 38. The blocks 40, 44 serve as the fixed electrode. The electrodes 36 are operated in turn bv a roller 76 carried by a spring-pressed slide 64 movable on a lever 66 which is mounted on and insulated from a pivot 68 at the centre of curvature of the work. The block 32 has a fixed cam 104 over each electrode 36 and as the lever is swung round the cams in turn press back a spring-pressed metal plunger 100 mounted in a spring-pressed insulating plunger 96 slidable in an insulating block 92 secured to the slide 64. The plunger 96 carries a contact disc 106 to bridge the contacts 108 and thus complete the welding circuit. In order that the lever may be reset in initial position without fouling the cams or operating the switch the slide 64 is pulled back by a toggle mechanism 114, 116, the lever 114 being moved past the dead point and engaging a. stop 118. The lever 114 is pivoted in a bracket 82 bolted to the lever 66.
