Title: Improvements in or relating to electric discharge devices
IPC: H01J9/395
Filed: 1955-05-24
Abstract: 798,751. Discharge apparatus. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. May 24, 1955 [May 28, 1954], No. 14932/55. Class 39(1). Mercury is introduced into an electric discharge device by heating, on a carrier inside the device, a mixture of mercury oxide with a quickacting reducing medium and a slow-acting reducing medium to retard the otherwise explosive speed of the reaction. A suitable mixture is HgO + Zr (as quick-acting medium) + Fe (as retarding medium) in the ratio 1 : 1 : 2. A pill of this mixture is fixed to a nickel carrier, and induction heated to about 700‹C., which initiates a thermite reaction. Nickel, manganese, chromium, or cobalt are alternatives to iron.

Title: Improvements in or relating to process for electrolyzing alkali metal brines
IPC: C25B1/36
Filed: 1950-06-16
Abstract: 695,877. Electrolysis of alkali-metal brines. MATHIESEN CHEMICAL CORPORATION. June 16, 1950 [June 23, 1949], No. 15071/50. Class 41. In a process for electrolysing alkali-metal brines containing iron in a concentration not exceeding 0.0001 grams per litre, magnesium in a concentration not exceeding 0.001 grams per litre, and substantially saturated with calcium sulphate but containing at least 0.8 grams per litre of calcium ions, utilizing a mercury cell, the pH value of the brine in the cell is maintained within a range of from 1.7 to 3.0, thereby suppressing the deposition of hydrogen. This range corresponds to a range of 1.7 to 3.5 in respect of the brine entering the cell. Brine leaving the cell may be dechlorinated with calcium sulphate made alkaline, freed from precipitated matter, and returned to the cell. Hydrochloric acid may be added to the brine to control the pH value.

Abstract: 908,483. Electron beam apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 12, 1959 [May 13, 1958], No. 15331/58. Class 39 (1). Deflecting means 18 are provided in an electron beam furnace to bend the beam EB<SP>1</SP> on its path from the cathode 9 to the hearth 1 and so prevent bombardment of the cathode by particles which are ejected or evaporated from the material being heated, e.g. niobium. The deflecting means 18 may be electric or magnetic and may be mounted inside or outside the chamber 2. The hearth 1, e.g. of copper, may be cooled and may be movable for scanning purposes, or scanning may be effected by varying the energization of the deflecting means or the position thereof. A beam-shaping electrode 13 and an apertured anode 14 are mounted in the cathode chamber 6, or the wall surrounding an aperture 15a connecting the chambers 6 and 2 may serve as an anode. The cathode 9 and aperture 15a may be elongated and may correspond in length to the width of the hearth 1. Diffusion pumps 3 and 7 are connected to a backing system by pipes 16 and 17. The cathode 9 and anode 14 are connected to terminals T1 and T2 respectively. The Provisional Specification describes a furnace (Fig. 1, not shown) in which the cathode 9, aperture 15a and hearth 1 are arranged in a straight line, bombardment of the cathode being reduced by the restricted size of the aperture.

Abstract: 958,319. Thermal switches. WILCOLATOR CO: April 24, 1962 [April 24, 1961], No. 15494/62. Heading H2B. A slow acting switch 10 comprises a pivoted operating lever 27 having a bridging contact 25 at one end and being acted on at the other end by fluid temperature responsive means for movement about a pivot point 30a intermediate its ends such that the contact 25 moves into and out of engagement with a pair of spaced stationary contacts. A control shaft 30 has its point 30a engaging in a recess 28 of lever 27 to form the pivot and is adjustable to set the operating temperature. A capsule 45 bears in a recess 47 on the other side of lever 27 against the bias of a leaf spring 35 to open the contacts with increase of temperature. The bridging contact 25 is self-aligning against the stationary contacts owing to the rounded point 30a, yet sufficient frictional resistance exists to inhibit movement as a result of vibration or jarring. The switch casing 11 has threaded openings 12b for receiving mounting screws.

Title: Magnetron Temperature Control
Inventor: MORRIS JOHN DENIS
IPC: G05D23/27
Filed: 1967-04-05
Abstract: 1,157,194. Automatic temperature control systems. HIRST (MICROWAVE HEATING) Ltd March 14, 1968 [April 5, 1967], No.15569/67. Heading G3R. To compensate for the heating effect of electronic bombardment of a magnetron cathode, the cathodic radiation is sensed by a photosensitive cell 20 which regulates the cathode heater current. A photo-resistive cell 20 sensing cathodic radiation is connected across a capacitor 21 forming one arm of a bridge circuit having other arms 24-28 controlling, through a transistor 30, the charging current of a capacitor 32 from a synchronized squarewave supply 37-40. The capacitor 32 is periodically discharged by a unijunction transistor 35 through a winding of a transformer 33 which supplies firing pulses to thyristors 17, the angle of conduction being determined by the resistance of cell 20. The heater supply 18, 19 has an NTC resistor 16 in series to limit the initial heater current to twice normal. The arrangement is stated to allow a greater degree of mismatch between a magnetron and a load than would otherwise be possible without deterioration of the magnetron. Where the magnetron output is fed to a continuously moving sheet which, if it suddenly comes to an end, no longer provides an absorptive load, a sudden increase in the reflected power incident on the magnetron cathode is compensated. The magnetron envelope has window which admits radiation from the cathode to the cell.
