Title: Improvements in and relating to remote control systems, e.g. for landing lamps of aircraft and the like
IPC: B64D47/04
Filed: 1941-02-24

Title: Improvements relating to electron discharge tubes for generating x-rays
IPC: H05H11/00
Filed: 1923-01-27
Abstract: 195,594. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Slepian, J.). April 1, 1922, [Convention date]. R÷ntgen-ray tubes. - A varying magnetic field adjacent to the cathode controls the path of the electrons to an anode or target so as to increase their velocity. By this means hard rays may be produced with relatively low voltages between the electrodes. In one arrangement, Fig. 1, a discshaped container 1, having a cathode 4 heated by current from battery 5 and an, anode 6 near the edge, is mounted between the disc-shaped pole pieces 9, 11 of a U-shaped magnet 12 which may be energized by a winding 13 in series with a battery 15. A winding 16 mounted around the edge of the container is energized by alternating current or a condenser discharge, and produces varying magnetic and electric fields which cause the electrons to move to the anode in spiral paths. In another arrangement, Fig. 4, a container 17 of toroidal shape, with a cathode 4 close to the inner wall and an anode 6 close to the outer wall, is mounted in a laminated iron core 18 of the shell type. A winding 23 mounted around the central part of the core is energized by alternating current or a condenser discharge. Magnets 27 of segmental shape are mounted above and below the container so as to produce transverse magnetic fields near the inner and outer walls of the container, thereby deflecting electrons from these walls. A source of energy 8 may be connected between the anode and cathode or may be omitted. Vacuum tubes.-The Specification, as open to inspection under Sect. 91 (3) (a), comprises also the application of the invention to electron discharge tubes. This subject-matter does not appear in the Specification as accepted.
Patent GB-376661-A (GB)
Title: Process for the manufacture of alkali dichromates
Filed: 1932-01-27
Abstract: Alkali dichromates, for instance sodium dichromate, are obtained by oxidation by a dry process above 300 DEG  C. and under pressure of a mixture of chromium oxide or substances containing it or of metallic chromium or its alloys with the requisite amount of the necessary base or mono-chromate.  Oxygen or air is preferably used for the oxidation and the pressure is such that decomposition of dichromate is avoided.  Excess of the chromium constituent may be used to prevent fusion, such excess being returned to the process.  When monochromate is a constituent of the reaction mixture intimate admixture of the reactants may be effected by subjecting them to a preliminary reducing treatment, for instance with hydrogen at 400 DEG C.  In examples temperatures of 300-500 DEG  C. and pressures up to 5 kgs. are used.

Filed: 1919-02-01
Abstract: 136,948. Martin, F. P. Feb. 1, 1919. Automatic. - feed weighers; liquidmeters.-In a liquid meter or a device for automatically deliver. ing equal weights of powdered, granular or fragmentary ma. terial wherein a rotary compartmented drum b is mounted on a lever d, the rotation of the drum during discharge of the material from a compartment is utilized to restore the drum to position for filling the next compartment. The lever d is supported at one end on a fixed pivot e, and at the other end on a shackle h suspended from a counterbalance lever f. The material from a feeding-device i enters the uppermost compartment of the drum, which descends and thereby frees a tooth a<3> from a catch c. The drum then rotates to discharge its contents, at the same time rocking a bent lever i by means of a projection a<4>. The bent lever engages a pin h<2> on the shackle h and assists the rise of the drum in readiness for another weighing operation, the action being continuous. A counter, and a recording-instrument with a pivoted pen for drawing diagrams, may be operated by a moving part such as the lever j, either directly or by means of a pneumatic, electric, or other suitable system.

[Class 118 (i)] A theft-alarm device for use in containers and handbags such as those carried by bank messengers is adapted to ignite successively a series of explosive charges and also a slowacting smoke-generating charge which gives a visible signal, time fuses and smoke-absorbing means being provided to enable the messenger to escape from the bandit before the explosion signals are given. When surrendering the bag to the bandit, the messenger retains by his finger a loop 65, thus pulling by means of a self-detachable wire 64 a trigger arm which releases the firing-mechanism for a fuse 27 connected (a) to fuses 21 of different lengths in chambers 15-18 loaded with explosive powder 19 retained by wads 20, and (b) to fuses 24 leading to chambers 22, 23 charged with a slow-burning powder adapted to generate a dense smoke. When the explosions occur, a thin leather cover 38 is blown away from the perforations in a base plate 37. In order to absorb the initial fumes from the fuses, which might disclose the alarm device prematurely, chambers 31 are provided containing absorbent material 33, baffles 35, and perforated screens 34. The fuse 27 is located in a tubular metal member 26<a>. U.S.A. Specification 1,934,731 is referred to.

Abstract: 593,195. Heating metal strip by electromagnetic induction. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Feb. 5, 1945, No. 2880. Convention date, Feb. 5, 1944. [Class 39 (iii)] A metal strip 1 passes over roller 2, into a furnace 3, heat soaking chamber 4, and through a quench tank 6. The furnace 3 comprises two opposite field structures 9, 9<1> having salient poles so arranged that the flux passes perpendicularly -through the metal strip 1. To avoid excessive heating at the strip edges the field structures 30, 30<1>, Fig. 7, may be movable transversely across the face of the strip so that one edge of each field. structure 31<1> 32 is located laterally inside the strip. Automatic following of the strip edge by the field structures may be employed to accommodate wearing of the strip, or varying widths of strip, by the use of regulating means comprising : an arm member 40 carrying a light source 44 and photocell 45, an amplifier responsive to the output of the photocell, and a reversing motor operated by relays energized by the amplifier. An alternative method of reducing the heating effect at the edges of the strip is shown in Fig. 11, the field structures being rotated about a pivot 70 and supported by rollers 71, to shorten the length of heating field traversed by the strip edges.

The transmission shaft f is connected to the change-speed gear. At starting, with the gear in the neutral position, the clutches are disengaged by means of the pedal 2, the motor is switched on, and when the fly-wheel m has attained a considerable speed the clutches are brought into engagement by the release of the pedal. A multiple-plate or other clutch may be employed and the field magnets may' rotate instead of the armature.
