Title: Improved method of and means for shaping and forging hollow metal bodies
IPC: B21K1/22
Filed: 1933-09-18
Abstract: 422,721. Forging hollow metal articles. GIACCHINO, E., 18, ChaussÚe de Charleroi, Brussels. Sept. 18, 1933, No. 25800. [Classes 83 (ii) and 83 (iv)] Hollow metal bodies are produced by electrically heating a tubular blank 2 at the portion X to be enlarged and applying internal pressure P on a deformable core 3 and also independent axial pressure y or y<1> on the blank to vary the wall thickness of the enlarged portion. The operation may be performed within a die 4, Fig. 7. The apparatus may be of the general type described in Specification 288,488, [Class 83 (iv)], comprising an anvil 6 in the form of a plunger of a hydraulic cylinder 9, a second hydraulic cylinder 10 for exerting pressure on the end of the tubular blank 5, the end of which is heated by electricity supplied from a transformer 18 to the anvil 6 forming one electrode and a clamp vice 8 forming the other electrode. Plunger 7 of cylinder 10 actuates another cylinder 11 mounted in guideways 41, cylinder 11 terminating in a tubular plunger 13 which exerts end pressure on the blank 5 ; the plunger 14 which exerts pressure on the deformable core of the blank is carried by the ram 15 of the cylinder 11. The deformable core is of loose or powdered material of low electric conductivity such as graphite.

Abstract: 449,655. Thermionic valves. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London. Sept. 20, 1935, No. 26103. [Class 39 (i)] Valves suitable for push-pull amplification at ultra-high frequencies contain in a single enclosing vessel several electrode units each comprising a cathode, a control electrode, an anode, and a fourth electrode between the control electrode and the anode, and the fourth electrodes of all the units are united to form part of a single structure extending to the wall of the vessel to separate the vessel into two portions, one containing the mutually insulated anodes and their separate leads and the other the control electrodes and cathodes and their leads. Two helical screen-grids 42, Fig. 1, are connected to a flanged shielding disc 37 extending across the vessel 10 and co-operating with an external metal shield 51. Outside the grids 42 and in the space below the disc 37 are helical suppressor grids 32 and anodes 34 with cooling fins 35. Inside the grids 42 are control grids, consisting of longitudinal rods, and central filamentary cathodes. The anode leads 36 pass through the bottom 12 of the vessel 10, and the control grid and filament leads through the top 11. The suppressor grids are connected to the cathodes. In a modification in which the shielding disc extends across the vessel at the bottom of the electrode units and is connected to the suppressor grids and in which the electrodes are positioned by upper and lower slotted insulators, the screen-grids 42, Fig. 8, and suppressor grids 32 consist of arched wires extending around the cathodes 19 from parallel metal plates 68, 74 forming a condenser coupling between the grids 32, 42. The control grids 25 are helices supported by flanged metal plates 47 and the anodes 34 have cooling fins 35 formed as shown. A getter of magnesium strip is supported on a small disc below the shielding disc. In another modification, the plates forming the condenser coupling extend as flat or curved discs across the vessel to act as the shielding disc, are relatively positioned at their edges by insulators and carry arched wires 42, 32, Fig. 10, forming screen and suppressor grids between each control grid 25 and anode 34. The wires 42 of each screen-grid may be mounted on a small plate adjustable on the disc 37 which extends across the vessel. In another modification, (Figs. 14 and 15, not shown), the plates carrying the screen-grids and suppressor grids are replaced by concentric cylinders with correspondingapertures for the electrode units, the outer cylinder having a flange extending to the enclosing vessel.

Title: Improvements in producing oxygen-free copper
IPC: C22C9/00
Filed: 1945-10-16
Abstract: Substantially oxygen-free copper is produced by subjecting a body of molten copper to the action of a hydrogenous reducing-agent to provide copper containing hydrogen in solution, and then removing the hydrogen by treating the copper with substantially pure boron or a boron-copper alloy, e.g. one containing 0.5-5.0 per cent of boron and less than 1 per cent of impurities, in amount preferably exceeding that required to remove all the hydrogen, generally 0.005-0.02 per cent by weight of the copper treated.  The copper may be saturated with hydrogen, e.g. by melting copper under a reducing atmosphere containing hydrogen in a reverberatory furnace or by melting the copper in a reverberatory furnace in contact with the heating gases and "over poling" the copper with green wood poles.  The resulting degassed copper may be cast in vertical moulds and has a density exceeding 8.9 grams per cubic centimetre.  The copper may contain 0.001-0.01 per cent of boron, e.g. 0.005 per cent. U.S.A. Specification 2,195,433 is referred to.
