Title: Improvements in vacuum electric discharge tubes or valves
IPC: H01J19/66
Filed: 1936-11-16
Abstract: 490,511. Two-part couplings ; sealing lead-in wires into vitreous envelopes; discharge apparatus. ROBINSON, E. Y., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Nov. 16, 1936, No. 25263. [Classes 36 and 38 (i)] [Also in Group XL] An electric discharge tube or valve of small dimensions has the lead-in wires sufficiently thick to act as supports for the electrodes and as plug contacts to co-operate with the valveholder. If the lead-in wires are few in number they may lie in a plane, being held by a temporary support 18, Fig. 1, and cross-wires 12 while the envelope 19 softened by heat is closed on the copper-clad part 10 of the leadin wires by a pair of jaws as described in Specification 481,940. The wires are riveted into one of the spacers 2, 3 that locate the electrodes and a single lead-in wire 15 may be sealed into the top of the envelope, using a glass bead 16 where adhesion is required and a nickel sleeve 17 or graphite coating where adhesion is not required. Where the lead-in wires are located on a pitch circle, the glass of the envelope is pressed around and between them and may be sealed to a glass cup placed within the circle of wires. The pins may be stiffened by means of a disc 37, Fig. 9, that may be secured by tubes 36 fixed in it and spot welded to the pins 31. Cement 38 may be introduced between the disc and the envelope. Alternatively, if the tubes 36 are not employed the pins may be flattened near the disc to hold it in place. The disc may carry a central guide spigot 40 with a key or web 41. This spigot is not required if the pins are asymmetrically arranged as, for instance, by applying tubes 36 to some of the pins so as to make them thicker and longer than the rest.

Abstract: A washing composition consists of soap or similar detergent in admixture with a water-soluble compound of a thiotetraphosphoric acid.  Alkali metal salts of tetraphosphoric acid (H6P4O13) in which one or more oxygen atoms are replaced by sulphur are used.  Examples are, sodium monothiotetraphosphate (NaP6B4 O12S) or the trithiocompound (Na6P4O10S3), are mixed with a sodium or potassium soap, or with sodium alkyl sulphonates containing 10 to 18 carbon atoms.  The soap may also contain borax, ammonium salts, ortho phosphates, oda sash or rosin. Other detergents specified are: oxalic acid with or without sodium acid sulphate, a dry mixture of sodium hypochloride and sodium bisulphate.  For the preparation of a washing bath, the ingredients are preferably added simultaneously, i.e. as a pre-formed mixture.

[Also in Division G3] The rudder of a boat is controlled electrically through a hydraulic pressure system via selsyn units on the steering wheel and on the rudder shaft, utilizing a magnetic amplifier which feeds a second harmonic dither voltage to the control coils of the system. As shown (Fig. 1), a constant pressure oil pump 11 feeds power to a rudder drive 16 through a regulating valve 13 controlled electromagnetically by solenoids 14, 15. Rotation of the rudder head 18 is measured by a selsyn unit 60, 62 (Fig. 3) mounted on the rudder shaft, connected to a selsyn unit 34, 35 associated with the control wheel. The difference between the signals in the stators 35, 60 is fed through a magnetic amplifier 36 to the control windings 14, 15 of the regulating valve 13, to make the rudder follow the control wheel. The magnetic amplifier supplies a continuous second harmonic dither voltage to windings 14, 15.

Title: Improvements in and relating to fire control apparatus particularly intended for naval guns
IPC: F41G5/16
Filed: 1920-09-07
Abstract: 168,251. Rogers, T. W., (Krupp Akt.-Ges., F.). Sept. 7, 1920. Ordnance sights; discharging by means external to breech mechanism.-Relates to gyroscopically-controlled electric firing gear for naval guns, and consists in providing a firing-gyroscope M which is adjusted to accord either with a distant gyroscopically-controlled observer's sight g' when the target is in view or with a fixed sight line determined by an auxiliary gyroscope J when the target is obscured by smoke or fog. In the form shown, the Wheatstone-bridge principle is employed to ensure concordance between the gyroscope G controlling the sight g' and the gyroscope M controlling the firing contacts a<2>, d<1>. For this purpose the stabilized axes g<2>, A of the gyroscopes G, M carry arms g<1>, a<3> moving over resistances H, E, the arms being connected by a bridge F, there being no deflection visible on the indicators f<2>, f<1> in the balanced position, corresponding to concordance of the axes g<2>, A. The axis A carries a plate a' on which is mounted an electric motor C connected through worm-gear to a sighting-telescope B, which can be adjusted to a mark viewed at infinity through a collimator glass i<2> controlled by the auxiliary gyroscope J. When the target is visible, a switch k<2> is closed by the observer to light a lamp K to show that the indicator f<1> is to be followed in setting the contacts a<2>, d', but when the target is observed, the lamp K<1> is lighted to show that the sighting-mark is to be followed by the telescope B. If, when the target is obscured, the gyroscope G is adjusted to accord with indicator f<2>, the target should subsequently reappear in the field of view. By adjusting the motor C through a hand-wheel c' the telescope G may be adjusted to compensate for slight variations in the position of the sight line determined by the gyroscope J. The telescope B and collimator i<2> may be dispensed with if a Wheatstone-bridge control is inserted between the gyroscopes M, J.

Patent GB-262071-A (GB)
IPC: B60T13/48
Abstract: 262,071. Bragg, C. S., and Kliesrath, V. W. Nov. 25, 1925, [Convention date]. Pneumatic relays.- In engines, the suction of which is utilized to operate a suction-actuated device, " stalling " of the engine and interference with the working thereof due to weakening of the combustible mixture by air withdrawn from the device, are prevented by connecting the space in which the vacuum is to be produced directly with one, or some but not all of the cylinders, at a point in the piston stroke at which the vacuum is at least equal to and preferably greater than that existing in the intake manifold. With this arrangement, even if the working of some of the cylinders is affected, the remaining cylinders will work normally since no extraneous air can be drawn into the intake manifold. The invention is described in its application to brake-actuation in road vehicles, but is not restricted thereto. The engine 60. Fig. 1, has its cylinders supplied from a carburettor 63 through an intake manifold 61 provided with a throttle valve 64. The brake 70 is actuated by an arm 72 connected through a link 73 with the rod 5 of a piston in the power actuator cylinder 1. The vacuum and pressure-controlled valves are located in the hub of the piston, and are actuated by a spring-loaded pedal 88 and a link 85. The right-hand side, of the piston is adapted to be placed in communication with fluid under pressure, and the left-hand side is in communication through a pipe 62 with, in the case shown, two cylinders 60a, 60<b> of the engine, but both sides of the piston may be subjected to a reduced pressure. At its junction with the cylinder, the pipe is provided with a spring-loaded check valve 66, which protects the actuator piston from the high pressures in the cylinder. The inlet valve is shown at 68. The port 62<a> is so situated that at the instant it is uncovered by the piston 69, the degree of vacuum in the cylinder is equal to or greater than that in the intake manifold, so that air drawn through the pipe 62 will not pass into the manifold and adversely affect the charges passing to the other cylinders. Specification 262,067 is referred to.
