Filed: 1919-05-20
Abstract: 127,256. Oakley, W. E. June 12, 1914, [Convention date]. Drawings to Specification. Valves.-An inlet or exhaust valve for internalcombustion engines is made from an alloy consisting chiefly of nickel, substantially free from carbon, and containing no aluminium.

By way of example, the alloy consists of approximately 67 per cent of nickel, 28 to 32 per cent of copper, and 1 to 5 per cent of iron. This alloy has the same coefficient of expansion as cast iron, resists corrosion at high temperatures, does not scale, and in use retains 80 per cent of its elastic limit and tensile strength. A hardened steel button is secured to the end of the valve stem for engagement with the actuating-cam.

Title: Improvements in or relating to electrical oscillation generators

Abstract: 400,995. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, and RUST, N. M., 109, London Road, Chelmsford. May 6, 1932, No. 13138. [Class 40 (v).] The output of an oscillator, employing a screen-grid valve as a negative resistance, is maintained substantially constant by rectifying its output and applying the resultant voltage as bias to a grid of the oscillator. As shown in Fig. 2, the tuned circuit 13, 14 is connected between plate and cathode of the valve 3 in the normal manner, the screen grid receiving a higher voltage than the plate due to the battery 11. A diode valve 1, in series with a condenser-shunted resistance 16, and a tapped battery 15 are connected across the tuned circuit. The resistance 16 is also in the control-grid circuit of the valve in series with a tapped battery 18, so that the bias on the control grid is dependent on the oscillator output. The batteries 15, 18 may be omitted, and the control grid connected to a slider on the resistance 16. A triode rectifier with adjustable grid bias may replace the diode 1. Fig. 4 employs a pair of triodes 33, 34 connected in push-pull as a full-wave rectifier. The grids are connected to opposite sides of the oscillatory circuit 13, 14 and the common cathodes are connected through a tapped battery to the mid-point of the coil 13. The plates are joined and connected through a battery 24 and resistance 16 to the oscillator cathode. In Fig. 5, rectification is effected by a double diode 38, 39 and the resulting D.C. voltage across resistance 44 is applied to the grid 40 of a triode, the plate circuit including an adjustable resistance LR, the battery 11, 12 and the condenser-shunted resistance 46. The voltage across the resistance 46 is applied as bias to the control grid 8 of the oscillator. The diode and triode elements are arranged in a common envelope 35.

Title: Improvements in electron discharge devices of the velocity modulation type
IPC: H01J25/12
Filed: 1947-05-15
Abstract: 653,833. Velocity - modulated tubes. WESTERN ELECTRIC CO., Inc. May 15, 1947, No. 13145. Convention date, June 26, 1942. [Class 39 (i)] In a velocity-modulation tube a retarding electrode 22, Fig. 1, is arranged between the input and output resonators 4, 23, which turns back slower electrons but allows faster electrons to pass on to and excite the output resonator 23, so that the velocity variations are converted into density variations without the use of a normal drift space. The resonators 4, 23 are made up of discs 17, 18, 20, 21 sealed through the envelope and separable portions 4 so that different sizes of resonators may be used for different operating frequencies. The resonator parts are maintained at a high positive D.C. potential, and when the input resonator is not excited the potential adjustments may be such that all or none of the electrons reach the output gap 24. The electrodes 14, 15, 31, 32 may have central grids or just single open apertures. Electrons which do not pass the electrode 22 may return through the input gap 16 in such phase as to give up energy to the resonator 4. Auxiliary electrodes may be provided to collect scattered electrons and to assist in maintaining the beam in focus, Fig. 3 (not shown). In another form, Fig. 2, the resonators have a common wall 50 which incorporates the retarding electrode 22. The wall 50 is insulated from the other resonator parts for D.C. but is coupled to them for the high frequencies by member 51. In a further form, Fig. 4 (not shown), the electrodes are arranged concentrically. The resonators in this case may surround the electrode assembly, or may be each disposed at a respective end of the electrode assembly without surrounding it. All forms function as amplifiers.

In one form, Fig. 2, when the sheath 4 is pulled outwards, the pin 13 springs out laterally and contacts with an enclosing ring member 11 integral with the sheath, and the pressure of the pin on the member 11 retracts the sheath so that the point of the pin may then be inserted in the sheath through the usual lateral opening. The pressure on the member 11 may be assisted by a helical spring 12, or by forming the pin 13 with a kink 14, as shown in Fig. 4. In the latter form, longitudinal movement is limited by a stop 17, with which contacts a projection 16 on a bar 5, which slides in a tube 18.
