Title: Process of and electric device for the treatment of a gaseous fluid
IPC: H01T23/00
Filed: 1973-07-11
Abstract: 1439014 Discharge treatment of gases G BRUNET A PRAMAGGIORE and R GUERIN 11 July 1973 [26 July 1972] 33103/73 Heading H1X [Also in Division H5] In an electric device for the treatment of a gaseous fluid comprising at least one treatment element to be disposed in the gaseous fluid to be treated, the treatment element comprising a first electrode 2 connected to a source 1 of unidirectional pulses of electric current, a solid dielectric material 5 so disposed about the first electrode 2 as to insulate electrically at least one face of the first electrode from the gaseous fluid to be treated, and a second gridlike electrode 3 disposed so as to cover at least partially the dielectric material on the side to be exposed to the gaseous fluid to be treated, the first electrode 2 comprises a continuous plate having a plurality of projections 2a uniformly distributed over the entire area of at least that face which faces towards tne second electrode 3. The element may comprise a plate 2 (Fig. 3) with stamped out portions 2a projecting on both sides of a median plane sandwiched between insulating layers 5 of thermoplastics material having a high dielectric constant and low dielectric loss, e.g. polyethylene or polystyrene, and stainless steel grids 3 and 4, with the projections 2a opposite holes 3a or 4a in the grids and providing pin-point zones 5a of smaller thickness than the remaining portions of the layers 5. Alternatively the zones 5a may have a higher dielectric constant than the remaining portions. The source 1 includes a half-wave rectifier diode 8, a switch 10 for varying the turns ratio of the transformer 6 and a variable resistor 11 for adjusting the output voltage. A resistor 9 prevents build-up of static electricity. In an alternative arrangement (Fig. 2, not shown) two banks of elements and two cylindrical alternative embodiments of the element are connected to the centre-tapped secondary winding of the transformer 6. The device may be used for the treatment of air containing pollutant molecules, e.g. SO 2 , H 2 S, NH 3 , CH 4  or other CH compounds to purify the air and increase the negative ion content.

Abstract: 1,008,099. Supply circuits for space discharge lamps. GENERAL ELECTRIC CO. Ltd. Sept. 10, 1962 [Sept. 15, 1961], No. 33180/61. Heading H2H. [Also in Division H1] An electric discharge lamp 10 (see Division H1) having a discharge channel long in comparison with its transverse dimensions and provided with three electrodes, one at each end of the discharge channel and one in the middle, is connected in an operating circuit which starts the two discharge reactions sequentially. The lamp 10 and a ballast inductor 13 are connected in series across the supply terminals 11 and 12. A transformer primary winding 18 with power factor correcting capacitor 19 and secondary windings 20 and 21 supply heating current to the lamp electrodes. A tapping is taken from the inductor 13 through a capacitor 17 to a terminal 16 of the middle electrode. On connecting a supply to terminals 11 and 12, substantially the whole supply voltage appears across terminals 15 and 16 so this discharge reaction starts, whereupon the voltage across terminals 14 and 16 rises sufficiently to start the other discharge section. In a modified arrangement (Fig. 4, not shown) the lamp ballast is capacitive and the heating supplies are taken from three secondary windings of a transformer whose primary winding is either tapped or connected as a step-up autotransformer to match the operating voltage to the main supply.

Title: An improved method for the halogenation of unsaturated hydrocarbons
IPC: C07C17/02
Filed: 1959-10-07
Abstract: Chlorinated or brominated hydrocarbons are prepared by reacting chlorine or bromine with an unsaturated hydrocarbon in the presence of a pre-cooled aqueous solution containing 2-6 moles per litre of a hydrohalic acid or an inorganic salt, said solution being employed in an amount sufficient to maintain the reaction temperature below the boiling point of the halohydrocarbon product.  The halogen and hydrocarbon may be reacted in countercurrent, and the solution passed as coolant through the reaction zone.  The production of ethylene dibromide from ethylene and bromine is exemplified.  Other suitable starting hydrocarbons are propylene, butylene, isobutylene, higher molecular weight olefines, diolefines such as butadiene, and acetylenes.  Specified components of the coolant solution are HCl, HBr, HI, inorganic bromides and chlorides such as NaBr, KBr, NH4Br and CaBr2 and the corresponding chlorides; NaI, KI, NH4I, NaNO3, NH4NO3 and Na2SO4.

Abstract: 154,921. Heyne, C. O. Dec. 4, 1919, [Convention date]. Stopping arrangements.-In a sheetfeeding device for printing - presses or tbe like, of the kind in which sheets are forwarded from a fanned-out pile by rollers as 1, 2, the fanned-out pile is supported on a table consisting of a grid of bars 4, and the pile is advanced intermittently bv a second grid, the bars E of which are raised, moved towards the feed rollers, then depressed and returned to normal position, the movements of the second grid being controlled by a feeler device which is inactive when the sheets are in a position to permit the feeding devices to act on the sheets. As shown in Figs. 1 and 2, the fecler consists of a lever M, which is mounted on a shaft N fitted with an arm M<1> with a roller 5 in contact with a cam L. When there is no sheet to prevent the upward movement of the lever M, this lever moves upwards when the cam L permits the roller 5 on the lever M<1> to drop into the cam recess. This movement of the lever M<1> causes a thrust pin P to actuate a latch Qu to connect a reciprocating rod T to a segment u which is thus oscillated by the rod T. The segment u gears with a shaft w fitted with a number of segments, each segment being connected by two bands y to a bar E of the movable grid. The bars E are thus advanced towards the pile by the segment u, and return by a spring z, the bars E being raised as they move forwards bv rollers D on arms C, C', mounted on shafts A, B, connected bv a rod G and lever arms F. The shaft A is oscillated by a, second cam on the shaft of the cam L, and a lever arm K. As soon as the sheets pass beyond the feeler M, the latch Qu is unlatched, and the means for advancing the bars E is thrown out of action.
