Title: Improvements relating to arc furnaces
Inventor: STEELE OWEN STEVENSON
IPC: H05B7/152
Filed: 1956-12-03
Abstract: 825,234. Automatic control systems for arc furnaces. BRITISH THOMSON-HOUSTON CO. Ltd. Dec. 2, 1957 [Dec. 3, 1956], No. 36931/56. Class 38 (4). Each electrode 3 of an A.C. arc furnace has its position controlled by a motor 10 so that the power taken by the arc is maintained substantially constant. The arc voltage is rectified at 6 and appears across R1, and a voltage proportional to arc current is obtained by current transformer 4 and rectifier 5 and appears across R2; these voltages are added and balanced against a reference voltage from potentiometer R3 by the use of amplidyne 9 with control winding 8, which supplies the armature of reversible D.C. motor 10. Since the control system acts to maintain the sum of the voltages across R1 and R2 constant, the power will be held substantially constant, at least for small changes in the voltages, since they are normally approximately equal. Instead of the mechanical coupling 12 between motor and electrode, the motor may move the electrode hydraulically by means of a pump, or the error voltage may be used to operate electromechanically controlled valves in an hydraulic system moving the electrode. In a further modification, an electronic amplifier or a magnetic amplifier as described in Specification 761,071 may replace the amplidyne 9.

Abstract: 794,034. Weighing-apparatus. WIRTH, A. Dec. 23, 1954 [Dec. 24, 1953], No. 37280/54. Class 143 An apparatus, for weighing large objects (e.g. aircraft), consists of load-measuring devices interposed between the ground surface and points on the object; load transmitting elements being provided at at least all but one of said points which form supports permitting a rocking action. In one embodiment the jacking point 2, Fig. 2, fixed to an aircraft, has a hemispherical end radius r) fitting into a spherical recess 4 (radius R) in the load transmitting member 3, where R > r. The member 3, contained in a hollow member 8, has a spherical convex lower end (radius x) resting on the flat face 6 of an abutment 7. The member 3 will be in stable equilibrium if h < x, and in neutral equilibrium, if h = x. Excessive inclination from the vertical is prevented by a flange 16 connecting with casing 8. The measuring devices (e.g. strain gauges) may be part of members 2, 3 or 7, or may be situated between any two of them. In another embodiment, the load transmitting member 3, Fig. 3, has a convex rolling face 18, with increasing radius of curvature with distance from the point of contact. Stability thus increases, as the inclination of member 3 to the vertical increases, until the conical zone 20 is reached. The rim 21 coacts with the frusto-conical face of abutment 7 to allow this inclination to be observed. A uniform gap 22 over the whole circumference indicates the exact vertical position. A spirit level 24 or a plumb line device may be provided for detecting an out-of-vertical position and an extreme position may be indicated by the closing of electrical contacts operating a warning device.

The bottom of a storage bunker 11 for coal &c. comprises a belt 13 supported by rollers 12. The belt 13 passes over a return drum 16 and its ends are connected (so as to form a composite endless member) by a link chain 18 which passes round a return sprocket 21. The belt is maintained under tension by an hydraulic ram 25 acting on the sprocket 21. Further rams 23, 24 act respectively on the upper and lower runs of the chain 18 to drive the belt 13 to the right and to the left. In operation, coal is fed to the bunker from a delivery conveyer 29 when the belt 13 is in its extreme leftwards phase of travel. The belt 13 then moves progressively to the right to deliver the coal to a storage condition in the bunker. When the bunker is to be discharged the belt 13 is moved rightwards to feed the coal to a conveyer 30.

A printed circuit panel as shown in Fig. 1 has conductors 11 with enlarged off-set terminal portions 15. Holes 14 drilled through the board and the terminals take the leads 12 of components 13 (Fig. 2), mounted on the opposite face of the board. Connections between the component leads and the printed conductors are made by immersing the side of the board, on which the printed conductors are mounted, in a bath of molten solder and then raising one edge (e.g. the one shown at the top in Fig. 1) so that the solder flows along the conductors 11 to the terminals 15.

A fuel cell comprises a fuel gas electrode, an oxidant gas electrode and an electrolyte, at least one of the gas electrodes comprising a porous layer of coherent metal particles in contact with the electrolyte and a gas-permeable layer of plastics-bonded carbon powder stuck to the metal layer and in contact with the gas. The metal layer may be of nickel. The carbon powder may be activated carbon, optionally carrying a noble metal catalyst, e.g. palladium. The plastics binder may be polythene dissolved in toluene, or P.T.F.E. emulsion optionally supplemented with polyvinyl alcohol solution. The plastics-bonded carbon layer may be sprayed or cast on to the metal layer, but in either case measures should be taken to ensure that no hydrophobic material remains on the electrolyte side of the metal plate. In Example 1, any polyethylene on the electrolyte side is washed off with a mixture of isopropanol and potassium hydroxide solution before the electrode is used as a hydrogen or oxygen electrode. In Example 2, plastics material is prevented from sticking to the electrolyte side by precoating it with carboxymethyl cellulose which is later washed off before the electrode is used as an air electrode. In Example 3, the carbon layer is applied as a paste including NH 4 OH and ethylene glycol and the electrode is used as an air electrode against hydrazine.
