Title: Burner control system
IPC: F23N5/20
Filed: 1966-01-12
Abstract: 1,079,085. Controlling burners. EMERSON ELECTRIC CO. Jan. 12, 1966 [Feb. 1, 1965], No. 1535/66. Heading F4T. A burner control system comprises a relay 16 which is energized at starting to close its contacts 18, 20 by a silicon controlled rectifier 28 controlled by a semi-conductor 26 responsive to the light of the burner flame. The relay 16 is energized to hold its contacts 18, 20 closed during burner operation by a branch circuit 86 fed from a tapping on the mains transformer. When a space thermostat 14 closes, the S.C.R. fires since the resistance of the semi-conductor 26 is high and consequently the relay 16 closes the contacts 18 to energize igniter electrodes 36 and a motor 12 supplying fuel and air to the burner. If ignition succeeds the resistance of the semi-conductor 26 drops and consequently the S.C.R. ceases to conduct but the relay is held closed by the branch circuit 86. If ignition fails the S.C.R. continues to conduct and the circuit is eventually de-energized by a manual reset bimetal safety switch 22 heated by a resistance 24 included in the S.C.R. circuit. If the flame fails during burner operation the starting sequence is carried out.

Title: Improvements relating to induction electric furnaces
IPC: H05B6/06
Filed: 1933-01-17
Abstract: 411,211. Supply systems for induction furnaces. DAVIS, N. R., 10, Atkinson Road, Sale, Cheshire, MARCHBANKS, M. J., 43, Radstock Road, BURBRIDGE, P. G. H., 23, Granby Road, both in Stretford, Manchester, KING, S. G. H. B., Brooklands House, Brooklands, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Jan. 17, 1933, No. 1578. [Class 38 (iv).] An induction electric furnace installation comprises an alternating-current generator system supplying two or more independent voltages in synchronism, the voltage systems being interconnected so as to give common leads, one or more induction furnaces associated with each voltage system, each system having a set of tuning condensers for power-factor correction, control equipment in the individual leads of each system, and switching means adapted to connect a larger furnace across two or more of the systems in series, and to disconnect the furnaces associated with those systems. In the example shown, the generator 1 has two windings 2 3 joined through contactors 4 7 to the common lead 6 connected to switch arms of switches 9, 10, and to individual leads carrying control equipments 21, 22 and connected to switch arms of switches 5, 8. Fixed and variable tuning condensers are connected across the leads. The small furnaces 12, 13 and the larger furnace 14 are connected to poles of the switches as shown. When the switches 5, 8, 8, 10 are all up, the furnaces 12, 13 are connected across their respective voltage supplies, and when the switches are down, the large furnace 14 is connected across the two supplies in series, while the power supplied by each winding is still limited by its own control equipment. If the switches are separate, one of them may be used as an isolating switch for switching off one of the smaller furnaces. If the two furnaces are similar the common lead 6 may be earthed. The control equipment comprises reactive K.V.A. relays controlling the tuning condensers, and power relays controlling the field rheostats of the generators. Auxiliary contacts on the furnace change-over switches which couple both generator control systems together may be provided to prevent the overloading of one generator in the case of both generators not being switched on together when in series. In a system having three independent voltage supplies a generator with three windings is provided. Each winding has control equipment, tuning condensers and a small furnace connected through charge-over switches. By suitable switches, a larger furnace may be connected across the three windings in series or across any two windings which have common leads. Furnaces may be connected in parallel across a single voltage supply.

Title: Improvements in or relating to the control of processes of which the rate of variation of the essential factor with respect to time varies with time
IPC: B01D37/04
Filed: 1942-02-07
Abstract: 554,145. Controlling filtering processes. NORTHERN ALUMINIUM CO., Ltd., and HORSBURGH, W. W. Feb. 7, 1942, No. 1640. [Class 46] [Also in Groups XXIX, III and XXVIII] A device for use in controlling a process in which the rate of variation of an essential factor varies with time, comprises two elements moved at right angles to one another one at constant velocity and the other at a velocity varying with the rate of variation of the essential factor, a member moved by the elements, and means actuated by a change in the direction of movement of said member for exerting control or giving a signal. Examples of processes to which the invention is applicable are those comprising mass action, filtration or distillation, and those in which one function is asymptotic to another. The apparatus shown with the parts in their initial positions comprises blocks 2, 4 and a member 1 which is pivotally connected to the blocks and is also slidable with respect to the block 4. During filtration, the block 4 is moved to the left by a cord 7, drum 8a, and clockwork, and the member 2 is raised by a rod 6 connected to a float in the filtrate receiving chamber, thus causing a weighted block 12 to be raised, pawls 15 on the block slipping over ratchet teeth on a bar 17 pivoted to a counterbalanced lever 19. When the delivery rate of the filtrate falls off, the direction of movement of the member 1 is reversed, the bar 17 is moved down, a trigger 21 is moved, and the weighted bell crank lever 24 swings the bar 17 to operate a valve 29, or other means, e.g. an electric relay, to cause a signal to be given or filtration to be stopped.

Title: Improvements in or relating to gaseous electric discharge devices
Inventor: ARROL WILLIAM JOHN
IPC: H01J9/395
Filed: 1953-01-21
Abstract: 738,182. Discharge apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 21, 1954 [Jan. 21, 1953], No. 1708/53. Class 39 (1). A method of manufacturing a gaseous electric discharge device comprises the steps of introducing tritium gas into the envelope of the device and producing an electrical discharge in the tritium gas whereby tritium is chemically fixed to a surface within the device. The tritium is effective as a low energy beta emitter calculated to increase the dark current and stabilize the striking voltage. It is believed that the discharge dissociates the tritium and that atomic tritium is fixed in the surface. In one example a cold cathode tube with electrodes in position ready for normal filling is first filled with tritium or hydrogen containing tritium at about a quarter of an atmosphere and an electrodeless discharge then initiated by means such as the point of a Tesla coil placed at a position outside the tube such that the maximum amount of tritium is fixed in a position nearest and exposed to the discharge gap or gaps of the tube. Alternatively, the point of the Tesla coil may be placed in contact with the Lead-in wire of one of the tube electrodes. The remaining tritium is then pumped off and the normal process of manufacture proceeded with. In a further example tritium is mixed with the gases normally used to fill the tube envelope. The tritium may be diluted with hydrogen according to the amount of hydrogen the particular type of tube is able to tolerate. If a gettering process is to be used the tritium is then fixed as in the previous example. In some types of cold cathode tube, however, no gettering process is used, in which case the initial discharge to fix the tritium may be dispensed with since the tritium will be fixed by the normal discharge during the operation of the tube. Specification 737,386 is referred to.

Title: Improvements in or relating to coatings
Inventor: ARCHDALE ROBERT WILLIAM
IPC: C25D13/02
Filed: 1950-01-24
Abstract: 691,859. Electrophoretic deposition. BRISTOL AEROPLANE CO., Ltd. Jan. 19, 1951 [Jan. 24, 1950; March 10, 1950], Nos. 1890/50 and 6124/50. Class 41. A method of applying a coating to a conduction surface of an article consists in preparing a slurry mixture having a pH value between 9.5 and 11.5 from an aqueous sol of silica or silicic acid and a finely-powdered filler material which is substantially neutral to the sol, applying to the article while arranged as an anode in the slurry an electric potential to deposit electrophoretically on the surface a layer formed of a mixture of the disperse phase of the sol and the entrained powdered material, removing the article from the slurry and drying the deposit. Before coating treatment the surface of the article may be treated with a degreasing agent such as sodium hydroxide, acetone or alcohol or with an etching fluid, for example by anodic etching with hydrochloric acid, or may be exposed to sand-blasting or shot-blasting. The surface may be coated with a metal, for example zinc or copper, before the electrophoretic coating. The composition of the zinc plating solution may consist of zinc cyanide, sodium cyanide, caustic soda, ammonia, and water. The filler material may consist of silica, alumina, sillimanite, olivine or other refractory material, or a mixture of two or more of such materials. Part of the filler may be replaced by one or more of the following: talc, zircon, clays, graphite, metal powders, for example of silver, copper, zinc or cadmium. The slurry may also contain a wetting agent, a reducing agent, or a compound containing or forming polar groups, examples of which are hydroquinone, resorcinol, glycerol, and dextrose. After the coating former has been dried it may be subjected to a firing process with or without treatment with an additional flux, glazing compound, or a silicon ester. The invention may be applied to the coating of a gas-turbine blade, a flame-tube of a gas turbine or the crown of a car piston.

Abstract: 715,077. Electrolytic production of chromic acid. BADISCHE ANILIN- & SODA-FABRIK. Jan. 24, 1952, [Jan. 26, 1951.) No. 1943/52. Class 4I . In the electrolytic oxidation of chromium salt solutions to chromic acid, tungstic or molybdic acid is added to the electrolyte in small quantities preferably amounting to at least 0.1 per cent by weight to prevent reduction of hexavalent chromium at the cathode. When diaphragms are employed the addition may be made to the cathode liquid only. The invention permits the use of wide-pored diaphragms. Cathodic current densities of at least 0.5, preferably I.5-4 amps per sq. cm., may be employed whereby current yields up to 8 3  per cent may be obtained. The process of the invention is especially advantageous when cathodes of tungsten or molybdenum or alloys of these metals with one another as described in Specification 715,075, are employed; in this way current yields up to 92 per cent may be obtained. In an example the bath consists of 10 litres of a solution containing 100 gms. of chromic sulphate and 350 gms. of sulphuric acid per lit. to which 2o gms. of tungstic acid are added while stirring. The cathode consists of I2 lead-covered copper wires and the anode of a lead plate of 100 sq. cms. area. Molybdic acid may be added to the electrolyte instead of tungstic acid. In another example the anode consists of a lead plate and the cathode of a similar lead plate housed within a cylindrical ceramic diaphragm.
