Abstract: 540,015. Thermionic valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 28, 1940, No. 3710. Convention date, Feb. 28, 1939. Class 39 (i)] In a heavy duty metal envelope valve for ultrashort wave working the cathode 12 is in the form of a U-shaped plate 12 the outer surfaces of the legs being fluted to receive the emissive coating, the wires 16, Fig. 3, forming the control grid and the wires 18 of a screen grid being opposite the ridges between the flutes. The cathode is carried by metal blocks 13, 14, Fig. 1, connected to the leads 5, 6 passing through insulating bushings 4 in the metal top plate 2; the control grid leads 7, 8 also pass through this plate. The two legs of the cathode form independent tetrodes with the grids and anodes, the control grids being supported by arms 21, 22, Figs. 1 and 2, attached to the leads 7, 8. The screen grids 18 are supported by similar arms 23 from a down post 25, brazed to the top plate 2; the grids are thereby at the potential of the envelope and there are no leads to these grids. The water cooled anodes 20 are each formed by blocks separated by a plate 30, Figs. 3 and 5, and formed with channels 28 between ribs 29 which are arranged to be opposite the points where the electrodes impinge on the anode : restrictions 33 prevent back pressure from the cooling fluid in the channels 28 acting on the water supply. Plates 36, Fig. 2, extending the length of the electrodes shield the grid leads from the anodes ; these are supported by leads 10, 11 passing through long glass bushings at the bottom of the envelope. For heavy currents the cathode may be braced against deflection by the field produced by the filament current by cross rods 39, Fig. 4, fastened to levers 40 joined through insulating bushings 41 to cross plates 42; these are fixed to water cooled columns 37. The lower ends of the control grids may be guided in a ceramic plate 43 spaced from a cross plate 38 which shields the plate 43 from heat and vaporized metal from the cathode This may have inturned strengthening edges 44, Fig. 2. The valve may be used as a push-pull amplifier or in oscillator circuits. The anode leads may be tuned to a desired resonance by a shorting bar 45, Fig. 7, adjustable from the outside by a screw 46, the bellows 47 maintaining the vacuum. The envelope has a water jacket.

Title: Motor Vehicles
Inventor: CAPON PETER COLIN
IPC: F16H61/22
Filed: 1967-01-27
Abstract: 1,163,176. Controlling change-speed gearing. FORD MOTOR CO. Ltd. 27 Jan., 1967, No. 4126/67. Heading F2D. In a motor vehicle transmission including a manual shift five-speed gear-box and a twospeed axle, downshift from a particular overall ratio to another particular overall ratio is blocked at all times. The five-speed gear and two-speed axle combine to give the following sequence of overall ratios: (numbers-gear ratios, letters-axle ratios) 1L, 1H, 2L, 2H, 3L, 3H, 4L, 5L, 4H, 5H. To prevent engine overspeeding, downshifts from 4H to any gear ratio combined with two-speed axle Low are blocked. A solenoid N1 is energized and deenergized by a switch S1 to pre-select High and Low ratios respectively of the two-speed axle, the selected ratio being established when the clutch pedal is depressed and the gear lever moved. When axle Low is engaged, a switch S3 is closed to energize a relay N3 to open its normally closed contacts C3. With ratio 4H engaged, switch S1 is on contact H, and a switch S2, closed only when fourth gear is engaged, is closed to energize a relay N2 to close normally open contacts C1, C2. If switch S1 is now moved to L, it completes via contacts C2 a holding circuit for relay N2 so that when fourth gear is disengaged and switch S2 is opened, N2 remains energized to hold contacts C1 closed to keep N1 energized. Thus the axle remains in High even though S1 has selected Low. Switch S3 is necessary to enable ratio 4L to be established from some ratio other than 4H.

Title: Improvements in the treatment of aluminium, magnesium, their alloys and other metals, to render them impervious to fluids, and to inhibit corrosion
IPC: C23C22/66
Filed: 1925-02-16
Abstract: 252,070. Daniels, S., Zimmerman, A. C., and Watson, J. A. Feb. 16, 1925. Annealing. - Aluminium and magnesium and their alloys, and other metals, are treated to render them impervious to fluids and to prevent corrosion by coating the metal with a solution oi a soluble silicate or silicates, and heating to affix the coating permanently to the metal. The silicate used is preferably sodium silicate, and the heating is carried out at a low temperature to render the metal tenacious and resistant to chemical and physical changes. In one method, the metal or alloy is immersed in an aqueous solution of a soluble silicate or silicates, preferably of a specific gravity between 1.05 and 1.3, for any desired period, the solution being kept at any temperature up to its boiling point. The metal is then baked with the silicate solution still adhering. In an example given, the metal is heated in an aqueous solution of sodium silicate of a specific gravity of 1.1 at 150‹ F. for two hours, and then removed from the solusilicate of a specific gravity of 1.1 at 150‹ F. In a second method, the metal is heated to a temperature not above 1300‹ F., e.g. to between 850‹ F. and 950‹ F. for a period between 2 and 144 hours, quenched in an aqueous solution of a soluble silicate or silicates, and then baked for a period of from 4 to 80 hours at a temperature between 200‹ F. and 400‹ F. In one example of this method, the metal is heated to 925‹ F. In one example of this method, the metal is heated to 925‹ F. for two hours, quenched in a solution of sodium silicate of a specific gravity of 1.1, and baked at 300‹ F. for not longer than 20 hours. This process, in the case of duralumin, increases the ultimate strength and elongation of the metal. In the third method, the metal is heated to some temperature not above 1300‹ F., cooled in air, water or oil, and then heated in an aqueous solution of a soluble silicate or silicates and baked under conditions similar to those described in the first method. In one example given, the metal is heated to 925‹ F. for 144 hours, quenched in water at room temperature, heated in sodium silicate solution of specific gravity 1.1 for two hours at 150‹ F., and finally baked at 300‹ F, for eight hours.

Abstract: 765,169. Ammunition projectiles. AKTIEBOLAGET BOFORS. Feb. 14, 1955 [March 22, 1954], No. 4311/55. Class 9 (1). The invention relates to cartridge cases for projectiles having a stabilizing tail. Fig. 1 shows a projectile 1 having a driving band 2 forming part of a carrier member or sabot screwed on to the projectile ahead of a tail equipped with fins 3 the fins and driving band being designed to contact the bore of the gun from which the projectile is fired. A sleeve 22 surrounds the forward end of the case to give a continuously tapering outer surface, while the inner surface of the end 5 is cylindrical. The case has a frusto-conical portion 7 merging into a portion 8 of smaller taper and into the base 9 is screwed a primer 10 connected to a flash tube 11 which is joined to the projectile, e.g. by one or more shear pins. The sleeve 22 may be provided with longitudinal slots, Fig. 2, or slits to render it springy. On placing the round in a gun, and firing the primer 10, the flash passes through the tube 11 to the charge to ignite the propellant. As the projectile is driven forward, the fins slide along the cartridge case before contacting the gun barrel. The tube or sleeve may be within the case as in Fig. 4 where the case and sleeve are engaged by a ridge 19v at the mouth of the case. This sleeve may extend for most or all of its length within the case. Instead of slots, grooves may be provided to receive the fins 3. In Fig. 4, the case 8v is of uniform thickness and tapered throughout its length. A sleeve 18v attached to the rim 19v of the case has grooves 21v to guide the fins 3 and is provided with perforations 20v and a pin 27 acting as a stop for the projectile.
