Title: Improvements in thermo-electric controls
IPC: G05D23/275
Filed: 1943-06-24
Abstract: 570,806. Control systems for heating resistances &c. PEARSON, L. H. June 24, 1943, No. 10205. [Class 38 (iv)] Switching control.-In order that a heating load, such as a blanket, may be quickly raised to a desired temperature, a thermal switch which has independent electrical heating means in parallel with'the load, is arranged, when sufficiently heated, to reduce the load current to a value sufficient to maintain the desired temperature. Fig. 1 shows five heating panels 76 ... 80 of a blanket connected in series with a preferably adjustable resistance R which is shunted by a thermal switch RT until the heating means HC has raised its temperature sufficiently to open its contacts. The thermal switch is adjusted to do this when the measured temperature of the blanket is that desired, and the resistance R is arranged to pass current sufficient to maintain this temperature. Indicating lamps L may be connected across auxiliary resistances r in series with each panel. In a modification, the thermal switch operates between two contacts completing the load to the full secondary winding of a transformer and the other connecting it to a selector switch associated with tappings on the winding. Modifications are described in which the thermal switch controls a thermal or electromagnetic relay which inserts the current-reducing resistance. The control may be applied on the primary circuit of a transformer supplying the load circuit.

Title: Improvements in or relating to transistor circuits

Abstract: 978,143. Electric meters; electric bridge circuits; liquid level measuring apparatus; indicating apparatus. BENDIX CORPORATION. March 14, 1963 [March 26, 1962], No. 10212/63. Headings G1J, G1N, G1Q and G1U. [Also in Divisions G4 and H3] The output voltage of a capacitive liquid level measuring bridge uses a circuit comprising a number of transistors of opposite conductivity type are arranged in cascade such that as the D.C. input signal rises the output voltage first rises and then falls. Fig. 1 comprises two such cascades in succession so that the final output voltage rises and falls twice. It is explained mathematically that so long as the signal voltage is below the level at which the respective output transistors 59 and 72 saturate the gain of each circuits is 2 but when they saturate the output voltage (e.g. E2) is related to the input voltage (e.g. E 1 ) by the relation E 2  = V - 2E 1  where V is the supply voltage. The circuit is used to measure the voltage from a liquid level indicator Fig. 3. The liquid level measuring capacitance 81 is connected in a capacitive bridge fed with alternating current from source 84 and having its output amplified at 85 rectified at 86 and 90 and then applied across a potential variable capacitor 83 in the form of a semi-conductor diode so as to balance the bridge, isolating chokes being provided to separate the A.C. path from the D.C. path. Rectified output from the amplifier is fed to a first meter 93 calibrated in metres and through a "folding circuit" similar to Fig. 1 to a meter 95 calibrated in decimetres. As the level of the liquid rises from 0 to 1 metre the pointer of meter 93 moves clockwise from 0 to 1 and the pointer of 95 moves in clockwise direction from 0 to 10. A further rise of 1 to 2 metres increases the reading on 93 from 1 to 2 but, as the output of the folding-circuit is now falling, causes the pointer of meter 95 to rotate in an anticlockwise direction towards its initial position, readings being taken from the inner scale. Further rise from 2 to 3 metres causes the pointer of metre 95 to move clockwise again while the rise from 3 to 4 metres causes pointer of metre 95 to return in an anticlockwise direction.

Title: Improvements in and relating to gas generators
IPC: C10J3/46
Filed: 1926-04-21
Abstract: 271,226. Umpleby, F. April 21, 1926. Coking processes; producers .-A gas generator for the continuous gasification of liquid and solid fuels by partial combustion is provided with a number of fuel nozzles which deliver the fuel in the opposite direction to a steam screen which serves to cool the residue and generate gas. The nozzles may be used to inject different fuels simultaneously and may be separately controlled. The material is fed through nozzles 5 into the gasification chamber 4a together with primary air which may enter through passages 5a and secondary air which enters through apertures 6 from an air space 3 in which it is preheated, openings 7 admitting the air to the apparatus. The gas as the result of partial combustion escapes through an outlet 8 and the residue passes through a screen 9 of steam which is thereby superheated and assists in the gasification process. The ash or residue passes through a passage 14 and is removed by a steam or air ejector 12. When starting, the gas from the burners 5 is completely burned to heat the apparatus. When the material is not completely gasified the residue may either be briquetted while hot or be collected in the form of powder. Materials such as aluminium, cerium, chromium, cobalt, copper, hafnium iron, iridium, lime, manganese, molybdenum, nickel, osmium, platinum, tungsten, zinc, zirconium or their salts or oxides may be employed to exert a catalytic influence upon the reactions, and may be fed through the injectipn nozzles or used in the composition of the inner walls. The generator may be used on motor vehicles. A series of generators may be employed one operating with solid fuel, another with liquid fuel the gases being passed from one generator through the other so that lean gas from one generator may be enriched by passage through another.
