Title: Improvements in the manufacture of steel
IPC: C21C5/56
Filed: 1940-08-13
Abstract: 543,245. Steel. WALDRON, F. B. Aug. 13. 1940, No. 12911. [Class 72] Steel is manufactured in a plurality of furnaces arranged in combination forming a sequence so that the metal flows continuously from one furnace to the next, each furnace containing an amount of metal to ensure that the incoming metal will disperse and circulate with it and maintain it at a constant level so that it will always flow out continuously, and each furnace being isolated so that it can be maintained continuously with the best slag, atmosphere and temperature for carrying out one or more of the reactions for converting iron into steel. The furnaces may be heated by gaseous, liquid or powdered fuels or electrically e.g. in a corelessinduction furnace and the others isolated to prevent the flow of slag or furnace gases from one furnace to the other. In the plant shown in Fig. 1, the iron from the blast furnace A flows through a trough B, intermittently or continuously into a mixer C. The metal flows continuously by a trough D to a gas-fired open furnace E where it is decarburized by the addition of iron ore or mill side fed thereto. The metal then flows through a trough F into a basic furnace G a gate L preventing the flow of slag, where it is de-phosphorized and the metal then flows by a trough J into a furnace K, a gate H preventing the flow of slag, where it is desulphurized. The metal then flows into a finishing furnace N where finishing materials which may include chromium, nickel and molybdenum, or pig iron to increase the carbon content or de-oxidizing agents such as ferro-silicon, ferromanganese or ferro-vanadium are added. In another form the metal flows from the mixer C to a converter thence into two electric furnaces in a sequence and then into a coreless-induction finishing furnace.

Class 106(5) [Also in Group XXVII] A fuel measuring device for internalcombustion engines comprises a freely reciprocating measuring piston d actuated by the fuel pressure and a reciprocating slide valve c disposed outside the piston d and arranged to control passages k, l connected to opposite sides of the piston d so that each serves alternately as an inflow and outflow passage. Fuel is supplied under pressure, e.g. by a diaphragm pump, to a slot i which in the position shown is connected by a passage o to the passage k, whereby the fuel pressure actuates piston d to force the measured quantity of fuel in the space e through passages l and q to an outlet passage m. At the end of the next stroke the valve c connects the passage l to the space i through a passage r and the piston is returned to force the fuel therebelow through passages k, p to a second outlet n. The piston stroke is varied by adjustment of the stop g by hand or in dependence upon engine speed. The outlets m, n may lead to separate injectors or a single injector, and the piston c may be adapted for controlling several pairs of outlets.

Abstract: 580,803. Cathode-ray tubes. FREEMAN, G. S. P. Aug. 30, 1940, No. 13635. [Class 39 (i)] A cathode-ray tube comprises a photo-cathode 5 and a fluorescent screen 7 in close juxta-position, and is activated after the parts are mounted in the envelope by a gas or vapour such as caesium, which may be deleterious to the material of the screen. To protect the screen, during the treatment of the cathode, the latter is formed with a lip 2, and is pivotally mounted at 4 in a stirrup 3, which in turn is pivotally suspended at 6. Before treatment, the cathode is turned through 180 degrees, for example by a magnet as described in Specification 469,079, about its pivot 4, and to provide the necessary clearance from the screen, the stirrup is swung aside as by tilting the envelope. The edge of the lip is then brought in contact with the screen, which is thus covered and shielded from the gas gr vapour during the treatment of the surface 5. After the treatment is finished and the envelope evacuated the cathode is restored to its operative position. In a modification, the stirrup is rigidly supported, and the necessary room for turning the cathode about its pivot 4 is provided by slidably mounting the screen on axial guides.
