Title: Method and apparatus for producing an electrical discharge
IPC: F23C99/00
Filed: 1965-09-01
Abstract: 1,112,612. Blow torches. NORTHERN NATURAL GAS CO. 1 Sept., 1965 [27 Oct., 1964], No. 37418/65. Heading H5H. An electric discharge distributed uniformly through a gaseous stream is established by maintaining a high-temperature gaseous piloting zone, introducing gas and ionizing additives into the zone to form ionized gases which enter the stream across which a suitable potential is maintained. A burner in which the discharge is established to raise the gas temperature comprises a refractory tube 9, Fig. 1, having a circular metal electrode 10 and a second electrode 11 within a tube 12. A combustible gas mixture is supplied between tubes 9, 12 and a cone-shaped flame extending between lines 15 is lit. A potential is applied by a step-up transformer 13 between electrodes 10 and 11. The piloting zone between electrode 11 and tube 12 indicated by lines 16, is maintained at a high temperature and ionizing additive is introduced into this area. Ionized gases emerge into tube 12 causing turbulence and spread over the entire flame. The high temperature is obtained by either maintaining a high current density in the zone, an arc discharge, burning within tube 12 an oxyacetylene flame or by recirculating a flame through electric heating means. The ionizing additive, e.g. Al, K or a metal salt, may be supplied in vapour form, it may be vaporized in the space by an electric discharge between the electrode and the tube, Fig. 5 (not shown), alternatively the electrode or the tube 12 may be coated or impregnated with an additive, the electrode may have a core of the salt or it may be of Al or K and vaporized during use. The tube and electrode may be replaced by three electrodes. In another embodiment, Fig. 9 (not shown), a gas stream to be heated flows through a tube (24) from which extend three electrodes (25) enclosed in casings (28). High-pressure gas containing an ionizing additive e.g. vaporized KC1 is fed into casings (28). A potential is applied between each electrode and casing to maintain an arc discharge which heats the gas before it emerges into tube (24) from nozzles (27) thereby creating turbulence. A three-phase potential is applied to the electrodes to create the distributed charge.

Patent GB-374544-A (GB)
Abstract: 374,544. Thermostats. SMALLWOOD, A. and FALLON, J., British Mills, Cornwall Road, Smethwick, Birmingham. March 21, 1931, No. 8745. [Class 64 (ii).] In a temperature control mechanism for furnaces, a pair of levers a, b, each of U-shape, are geared together by two pairs of pinions c, d, and are adapted to be periodically opened and closed by a reciprocating rod e. The free ends of the levers are provided with a pair of gripping jaws f, g adapted to grip a moving coil galvanometer needle h which moves in response to temperature changes. If the needle is in such a position that it is gripped, the jaws are held open and a mercury switch i is tilted to control a relay circuit which controls the motor circuit of a fuel valve. The rod e carries a projection o which operates a lever p carried by the switch. A lever s dependent from the lever b carries a rod r with a member q which, when the jaws cannot close, is retracted into the path of the switch i, which is thus prevented from falling and closing the contacts m, n. In these circumstances, the contacts l, m, which are closed by the rising of the rod e, remain closed. The jaws may be associated with a temperature recording apparatus, the lower jaw bringing the paper up against a needle which is held and moved into position by the upper jaw.

Abstract: 1,160,992. Controlling hydrostatic transmissions. ROBERT BOSCH G.m.b.H. 22 Aug., 1966 [23 Aug., 1965], No. 37465/66. Heading F2D. [Also in Division G3] A control system for a variable delivery pump comprises a piston 13<SP>1</SP> connected by a link 29 to the swashplate 31 of the pump 30 the piston 16 housing a control valve 18. Pump delivery pressure is fed through conduit 11<SP>11</SP> to a chamber 15 at the smaller area side of piston 13<SP>1</SP> and through a passage 20 in the piston rod and port 23 in the valve 18 to the interior of the valve so that outlet pressure acts on the valve 18 to urge the valve into contact with a beam 45<SP>1</SP>. The valve 18 controls the connection of a passage 21 in the piston rod with the passage 20 and exhaust port 22<SP>1</SP>. The beam 45<SP>1</SP> is subjected to a force provided by spring 43 in opposition to the outlet pressure and normally pivots about a point 46 on an element 47. The point of application of the spring force is adjustable by movement of a slide 36. When the output pressure varies the beam 45<SP>1</SP> tilts to allow movement of the valve 18 and thus the piston moves to cause a variation in the point of application of the valve 18 until the movements on the beam 45<SP>1</SP> are balanced and the valve 18 is recentred. When the valve 18 is below the roller 40 or between the roller and pivot 46, zero stroke regulation is obtained. When the valve 18 is to the left of the roller 40, the beam is moved off the pivot 46 to abut a stop 48. When the slide 36 is moved to the position E, the beam 45<SP>1</SP> is moved off the pivot 46 and abuts a stop 52. Under these conditions the angle of the swashplate is adjusted manually by movements of a slide 61 which rotates a bellcrank lever 49 to move the member 51 which is guided by a pin 55 in a slot 54. When the valve 18 is in the range E to D, the delivery direction of the pump is reversed and the control is purely by the manual slide 61. In place of the slide 36, the rod 38 may be swung relatively to a curved surface. The pump may form part of an hydraulic transmission. In this embodiment, Fig. 4 (not shown) a single adjustable member is formed with cam grooves to provide the adjustments of the slide 36 and the bellcrank 49. This member also adjusts the fuel flow to the engine driving the swashplate pump.
