Title: Improvements in or relating to fuel control systems
IPC: F23N5/20
Filed: 1955-12-09
Abstract: 792,930. Controlling burners. WHIRLPOOL-SEEGER CORPORATION. Dec. 9, 1955 [Dec. 9, 1954], No. 35466/55. Class 75(1) [Also in Group XXIX] A fuel flow control device for a burner comprises a pair of electrically operated valves 14, 37, Fig. 3, mounted on a body 41 carrying two switches for controlling the valves, one 24, Fig. 5, being thermosensitive and dependent on the lighting of the burner, and the other 16 a time delay switch effective to stop fuel flow if lighting does not take place within a predetermined time. On closing switch 12, Fig. 5, solenoid 13 is energized via cold bi-metal switch 16, the dotted position of switch 20, and the cold, dotted position of flame switch 24 from the mains 10. 11. This opens valve 14 allowing fuel to flow to a pilot burner 30 and moves switch 20 to its full line position connecting the solenoid 13 directlv to the mains 11. The pilot burner is lit from an igniter 29 connected to the mains through a transformer 25 and the flame switch 24 in its cold, dotted position. Should the pilot burner not light, mains current through the cold flame switch opens the bi-metal switch 16 after a delay by the heater 17 so that the apparatus is placed in its initial position. When the pilot burner heats a thermal bulb and bellows 33 the switch 24 is moved to its full line position whereby the mains energizes the solenoid 35 to open the main burner valve 37. The valves comprise discs 49, 91, Fig. 3, attached to armatures 54, 94 by clips 93, the solenoid armatures being sealed from the fuel by diaphragms 59, 37. The diaphragm operated pressure regulating valve 62 is situated in between the valves 14, 37. The switch 20 is actuated by a hinged armature 19 and fixed core 99 of solenoids 13.

Title: Improvements in or relating to logarithmic amplifiers
Inventor: HARRISON DONALD
IPC: G06G7/24
Filed: 1960-10-18
Abstract: 944,106. Analogue computers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 13, 1961 [Oct. 18, 1960], No. 35777/60. Heading G4G. In an amplifier having a logarithmic input/output characteristic provided by means of a thermionic diode D1, limited to low-current values so as to exhibit an exponential relationship between current and voltage and connected in series in a negative-feedback path around the amplifier 1, and in which compensation for changes in operating characteristics of the diode D1 with ambient conditions is provided by means of a further similar diode D2 connected in series in the feedback path and supplied with a current lying within the range of values carried by the diode D1 and varying similarly in response to changes in ambient conditions with the current in diode D1 so as to provide said compensation, the current to the diode D2 is supplied from a transistor T3 which is supplied from a normally balanced differential circuit 2 but which becomes unbalanced when the current through diode D1 exceeds a certain value so as to increase the current supplied by transistor T3, thence maintain the current through the diode D2 constant despite the increased drain therefore from the diode D1. For small inputs the current fedback through D1 is much less than the standing current in D2 so that variations therein do not have a significant effect on the current in D2. Under these conditions the potentials at the bases of the transistors T1, T2 vary similarly so that the base current supplied to the transistor T3 remains constant. Hence a constant current flows through diode D2, upon which variations in the feedback have no significant effect. In larger values of feedback however the current through diode D1 has a significant effect upon the potential at the base of transistor T1 thus upsetting the balance of circuit 2 and providing an amplified differential output at the collector of transistor T1, this being applied to the base of transistor T3 to alter the current supplied thereby so as to maintain the current through diode D2 constant.

Filed: 1958-11-07
Abstract: 874,610. Variable waveguide attenuators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 6, 1959 [Nov. 7, 1958], No. 35849/58. Class 40(8) A transmission line attenuator comprises two transmission lines 1, 2 (e.g. waveguides) coupled by a directional coupler 3 (e.g. a 3db. coupler) and terminated by adjustable short-circuits 4, 5, the (input) transmission line 1 being provided with a ferrite isolator 8. The short-circuits 4, 5 may be in the form of plungers ganged together for equal simultaneous movement in opposite directions. When the plungers are equidistant from the junction the whole of the reflected energy is coupled into the output line 2 and the attenuation is a minimum. Minimum output occurs when the plungers are separated by one quarter-wavelength when the reflected energy is all absorbed in the isolator. The phase of the output is constant over the attenuation range. The pistons may be moved differentially by means of a pair of oppositely-handed linear cams 11, 12 bearing on the spring-loaded rods 14, 15 of the pistons. An adjustable stop 18 determines the range of movement of the pistons and enables the apparatus to be adjusted for use at different frequencies.

Title: Method of producing persilicates of increased stability with high content of hydrogen peroxide or active oxygen
IPC: C01B15/14
Filed: 1934-12-14
Abstract: Persilicates or persilicic acid of increased stability are obtained by practically fully dehydrating the hydrous compounds in vacuo, if desired in the presence of stabilizers such as chloride, sulphide, cyanide, urea, or barbituric acid.  Practically fully dehydrating is defined to mean dehydration to a water content of about 1 per cent. The hydrous compounds may be prepared by precipitation from silicate solutions, by adding silicon dioxide hydrate to a metal peroxide, by crystallization from a solution of a silicon compound in hydrogen peroxide, by anodic oxidation, or by cathodic reduction of oxygen. In examples: (1) Hydrogen peroxide is poured over freshly produced silicic acid and the mixture distilled in vacuo to obtain the compound SiO2.H2O2. 2H2O.  By continuing the distillation in vacuo on a water bath at higher temperatures, first the monohydrate and finally the anhydrous compound is obtained; (2) Lithium silicate is dissolved in hydrogen peroxide solution and the solution distilled to obtain the compound Li2SiO3.H2O2.H2O, which is then dehydrated in vacuo; (3) Sodium silicate is dissolved in hydrogen peroxide solution and the cooled solution treated with barium chloride to precipitate the compound BaSi2O5.2H2O2 3H2O, which is then dehydrated in vacuo; (4) Lithium peroxide and silicon dioxide hydrate are ground together to a fine powder and the mixture carefully warmed to obtain the persilicate for dehydration; (5) A concentrated solution of sodium metasilicate is subjected to anodic oxidation using platinum foil electrodes.  A high current density is employed and the solution cooled.  The persilicate produced is dehydrated; (6) A solution of sodium silicate in a solution of hydrogen peroxide is electrolyzed using a lead peroxide anode and a copper amalgam cathode, the current density being very low.  Oxygen or gases containing it are blown against the cathode and a negative catalyst such as gelatine is added to avoid production of oxygen.  The persilicate produced is dehydrated.  In examples 5 and 6, diaphragms may be used, if desired, consisting of asbestos with adhesive and filling materials, or cement materials, or a mixture of aluminium oxide and silicic acid.
