Title: Improvements in process of generating power involving catalytic oxidation
IPC: F02B51/02
Filed: 1949-03-17
Abstract: 690,804. Generating combustion products under pressure. HOUDRY, E. J. March 17, 1949, No. 7336/49. Class 51(i) [Also in Group XXVI] Compressed air, fresh fuel, and previously oxidized fuel are admitted to the combustion chamber of a gas turbine or other power plant in such proportion that the mixture is too weak to ignite under the operating conditions. Oxidization of the fuel is secured by the presence of a reducing oxidizing catalyst. An example of the catalysts mentioned is copper manganese finely divided over an activated alumina support. The gas turbine plant shown in Fig. 2 is of the partly closed circuit type. Turbines n, p in series drive compressors t, u. Part of the exhaust from turbine p is returned to the circuit at 17 and the rest goes to a turbine r which drives a make-up compressor s. An interstage cooler o between the compressor stages t, u acts as a reheater for the working fluid, giving up heat first to the fluid in pipe 12 connecting turbine stages n, p and then to fluid in pipe 14 connecting turbine p with turbine r. The air from compressor u passes to the combustion chamber and fuel is supplied thereto by a pump P. In another plant there are three turbines in place of turbine n with catalytic re-heat chambers between them. Air from the delivery of pump s is further compressed and passed to the re-heat chambers. In the plant shown in Fig. 4, there are four combustion chambers 50, 60, 70, 80 with inlet and outlet pipes controlled by valves 56. With the valves as shown, chamber 50 receives compressed gas from pipe 61 and fuel from pipe 59 and discharges working fluid to turbine 51. The inlets of chamber 60 are closed and the contents of the chamber expand and pass through a reducing valve 55 to the low-pressure turbine 52. The chamber 70 receives scavenging air from a pipe 71 and discharges it to atmosphere by pipe 62. The upper inlets of chamber 80 are closed and the chamber is filled with compressed gas from compressor 53 through a restricted orifice 58. The valves are manipulated so that these four operations take place in turn in each chamber. Specifications 494,098 and 690,805 are referred to.

Title: Blending type liquid dispensing unit
IPC: B67D7/74
Filed: 1962-02-27
Abstract: 967,374. Dispensing liquids. GILBERT & BARKER MANUFACTURING CO. Feb. 27, 1962 [March 6, 1961], No. 7573/62. Heading A4T. [Also in Divisions B1 and G4] In a liquid dispenser, two liquids may be mixed in predetermined ratios according to the setting of a handle which simultaneously adjusts the cost of the mixture. Handle 42 is rotatable to one of a number of predetermined positions according to the ratio of premium and standard grades to be drawn from pipes 10, 12. Failure to attain the exact position in which a pin 56 enters a hole in disc 52 prevents operation of the pumps. The handle 42 rotates a segment 64, Fig 3, to adjust a variator 36 of the type described in Specification 957,782 whereby unit cost is displayed and the drive to the total cost register is adjusted. The blend is indicated as a window 226. The handle also rotates a disc 94 carrying a number of dogs 98, adjustable individually along the inside rim of the disc according to the price of the appropriate blend. Adjustment of the disc 94 drives a pinion 104 and so sets an index wheel 114 with notches engageable by a roller 126, Fig. 6, on a lever 128. The lever 128 is connected by an adjustable turnbuckle 134 to a camplate 146 whereby the handle 42 and disc 94 must be correctly set before dispensing can take place. The index wheel 114 is connected to a spiral cam 116 to adjust a bell-crank 48 and a link 152 whereby valve plugs 164, 165 in the blender 22, Fig. 8, are adjusted in opposite direction to vary the mixture. The amounts of liquid passing through the valves are separately metered at 24, 25, the amount being added in a differential mechanism (Fig. 10, not shown) to drive a shaft 34 leading to the volume register and through the variator 36 to the total cost register. If the price of all blends is increased by the same amount the disc 94 can be rotated relative to its previous position after undoing a lock-nut (102, Fig. 4, not shown). Modification. For dispensing a petrol-oil mixture the mechanism is broadly similar except that the stroke of an oil-dispensing pump, Fig. 11, is varied by the bell-crank 48<SP>1</SP> varying the effective length of oscillatory lever 318.

Title: Driven pulse generator

IPC: H03K4/50
Filed: 1963-02-28
Abstract: 993,445. Transistor pulse circuits. RANKBUSH MURPHY Ltd. Feb. 28, 1964 [Feb. 28, 1963], No. 8038/63. Heading H3T. An advance (or delayed) pulse generator comprises a sawtooth generator triggered by each initial pulse, the sawtooth waveform being coupled via a capacitor to a comparator circuit which generates an advance (delayed) pulse when the sawtooth waveform reaches a predetermined value and means to prevent excessive variation of change in the capacitor in the absence of one or more of the initial pulses. In Fig. 1 the sawtooth voltage is generated by charging C1 negatively via a constant current transistor 2 and periodically discharging it via a transistor 4, turned on by each initial pulse. The sawtooth waveform is coupled by C5 to the base of transistor 6 which becomes conductive at a voltage dependent upon the bias supplied via resistor 8. A pulse is thus initiated at terminal 9 at this instant, delayed with respect to the previous initiating pulse, i.e. advanced with respect to the next initiating pulse. NPN transistor 10 is normally conductive only for the duration of the output pulse, but becomes continuously conductive in the absence of one or more initiating pulses so as to prevent the accumulation of a large charge in C5. The period of malfunctioning following the omission of initiating pulses is thus reduced. In Fig. 3, input pulses at 21 are fed via a diode 22 and a mono-stable circuit comprising transistors 24, 25, to a switching transistor 32. Capacitor 35 is charged via a constant current NPN transistor 36 and discharged by transistor 32 at the time of each pulse from the monostable circuit 24, 25, the resulting sawtooth voltage being coupled via capacitor 40 to a transistor 41 which becomes conductive at a time adjustable by variation of the bias supplied via resistor 42, so as to initiate a pulse at the collector. This pulse is shaped by a trigger circuit comprising transistors 48, 49 and emitted by terminal 50. NPN transistor 61 operates as described in relation to transistor 10 in Fig. 1. The invention is applicable to the generation of advance pulses in multi-standard television systems.
