Title: Tungsten inert gas arc welding striking device
IPC: B23K9/073
Filed: 1973-02-14
Abstract: 1404374 Ignition apparatus for arc welding systems MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 14 Feb 1973 [18 Feb 1972 (8) 8 Nov 1972] 7354/73 Heading H2H Ignition apparatus for striking an arc in an arc welding machine comprises means whereby the charge on a capacitor is caused to discharge through a coil in a single pulse at any desired instant in the half cycles of the normal welding current whereby a voltage pulse is injected into the welding circuit so as to strike an arc. An A.C. source is connected to a terminal 2 so as to supply current to a welding electrode connected to a terminal 3 by way of a coil CC magnetically coupled to a coil L, the coil L being connected in a closed circuit including a capacitor C1 and a discharge type switch SW having main electrodes 4, 5 and a trigger electrode P. The capacitor C1 is charged from a D.C. source E1. When it is desired to initiate an arc in the welding machine a pulse is applied to a thyristor SW1 whereupon a capacitor C2, which has been previously charged from a D.C. source E2, discharges through an autotransformer I.C. thus to produce a pulse at the trigger electrode P of the discharge switch SW. The switch SW becomes conductive so that the capacitor C1 discharges through the coil L thereby inducing a single pulse into the coil CC to initiate an arc in the welding machine. When it is desired to re-strike an arc during welding it has been found to be preferable to have the capacitor to C1 charged to a lower potential and the capacitor C2 to a higher potential and to this end switches SW2, SW3 are provided. Alternatively the capacitance of C2 may be variable. The trigger pulse for the switch SW may be arranged at any desired instant in the waveform of the welding current supply and it may further be arranged that the positive and negative half cycles of the welding current have the same effective value. The welding voltage waveform may be rectified and compared with a D.C. reference voltage to provide a pulse for the switch SW. It is said that the interference produced by the apparatus of the invention is reduced from that of a known spark type arc striking apparatus.

Filed: 1922-03-15
Abstract: 180,982. Soc. Anon. Le Carbone. June 3, 1921, [Convention date]. Air or gases supplied; electrodes; carbon electrodes, making.-A cell employing zinc and carbon electrodes g, a in a solution of ammonium chloride is provided round the carbon electrode with a conducting porous mass b of wood charc o a 1 agglomerate, which projects at its upper end into the atmosphere to assist depolarization. To prevent the mass b from becoming saturated with electrolyte it is surrounded with a layer of material c which is only slightly pervious to liquids. This layer may consist of a jelly similar to that used as the electrolyte absorbent in dry cells, and is contained in a porous jar d closed by wax &c. e. The wood charcoal is agglomerated under high pressure and is burnt to eliminate the hydrocarbons contained in the agglomerating agent. A dry cell may be made by dispensing with the jar d and material c and using a fixed electrolyte in a zinc vessel which forms one electrode. The carbon electrode with the surrounding mass of wood charcoal both extend into the atmosphere through the wax closure at the top of the cell. The carbon electrode may consist of several strips of ordinary carbon alternating with strips of wood charcoal agglomerate, the whole being pressed together. The Specification, as open to inspection under Sect. 91 (3) (a), describes also a modification in which the charcoal instead of being agglomerated merely surrounds the electrode and is enclosed in a canvas bag; it may be mixed with better conductors such as plumbago. This subjectmatter does not appear in the Specification as accepted.

Title: A method for processing crude gases obtained on halogenating metallic ores
IPC: C01G1/06
Filed: 1950-03-27
Abstract: Gases obtained by halogenating metal ores are admixed with a colder gas in such proportion that a temperature is reached near the lowest point in the temperature range within which condensation of solid metal halides takes place, but is higher than the dewpoint of the halides which condense to a liquid.  The process is particularly described with reference to the precipitation and removal of small amounts of ferric and zirconium chlorides from gases containing titanium chloride, obtained, say, by the chlorination at 900 DEG C of briquettes of rutile, coke and pitch previously calcined in a reducing atmosphere at 800 DEG -1000 DEG C.  Prior to the addition of the cooling gas, the reaction gases may be cooled to a temperature higher than the point of precipitation of the solid chlorides by other means.  The cooling gas may comprise carbon monoxide or dioxide, nitrogen or a chlorination gas from which at least the solid chloride has been removed, at say 110 DEG C.  The cooling of the returned gas may be effected by cooled pipes or by injecting titanium chloride into the gas.

Filed: 1922-03-17
Abstract: 194,545. Stone & Co., Ltd., J., and Honey, A. E. March 17, 1922. Electromagnetic switches; locking; contacts.-An electromagnetically actuated switch, applicable for - use in lighting systems for railway vehicles, comprises two poles coacting with a pivoted armature in such a way that either or both poles may be energized to effect three angular positions of the armature. The iron-clad casing b, Fig. 1, carries two poles c, each with its own winding a, d<1>, and coacting with the centrally pivoted armature g carrying arms o, o<1> on which are bridging members for the pairs of fixed contacts t. Each bridging member comprises two carbon or like brushes r connected by a spring-controlled member s, each engaging one stud of a pair of studs t, as shown in Fig. 2. A diagram of connections is shown in Fig. 4, wherein 1 is a dynamo, 2, 2<a> arc lamps, 3, 3<a> the batteries, 4 a guard's control switch, 6 a battery change-over switch, and 7 a charge regulating resistance. The switch 4 is adapted to connect the terminal 4b with either of the terminals 4<a>, 4<c> or with both, so as to engage either of the windings d, d' or both. When the winding d is energized, the armature moves so as to bridge the upper righthand pair, and the lower left-hand pair, of contacts t, thus enabling the dynamo 1 to charge the batteries and for this purpose introducing the resistance 7 into the circuit. When both windings d, d' are energized, the armature g is moved to the mid position and the middle pair of righthand contacts will be bridged thereby causing the battery 3 to light the lamps 2. When the winding d' is energized, the lower pair of right-hand, and the upper pair of left-hand, contacts will be bridged and both sets of lamps will be across battery 3. To prevent magnetic short-circuiting between the poles c when either is energized singly, the yoke is reduced at n and the armature pole l slotted at m, the flux being thereby driven along the armature and into the yoke through the salient pole f. If desired, the armature may be mounted eccentrically with the curved pole faces so as to draw the pole l with greater force towards the outer end of the adjacent pole c. As the windings are only energized during the short period required for operating the switch, latching means are provided. These comprise a spring- edged latch y engaging notches in the face of the pole l. These latches will be magnetically withdrawn from engagement when the switch is operated, thus facilitating the movement of the armature. Specification 26187/05 is referred to.
