Title: Improvements in and relating to centrifugal fans
IPC: F04D29/42
Filed: 1938-02-18
Abstract: 496,984. Centrifugal fans. ANDERSON, E. L. Feb. 18, 1938, No. 5116. Convention date, Oct. 6, 1937. [Class 110 (i)] In a centrifugal fan with a plurality of inlet vanes 23, each vane has a radial leading edge 29 and a non-radial leaving edge 30.

Title: Unloader valve assembly
IPC: F16K17/10
Filed: 1972-02-04
Abstract: 1364973 Valves J L KRECHEL 4 Feb 1972 [26 April 1971] 5337/72 Heading F2V A valve for automatically unloading a compressor or the like when fluid delivery to a pneumatic load is temporarily undesired, comprises a valve body 3 having an inlet 7 for connection to the compressor, an outlet 9 for connection to the load, and an exhaust port 11 leading to atmosphere. Main and auxiliary valve closure members 13, 45 are shown in the unloading position whereby the compressor is connected to the exhaust port 11 via passages 7, 51, 53 and 23. The creation of a suitable pressure differential across the valve due to tapping the load or starting a stationary compressor, causes both closure members 13, 45 to move rightwardly against the action of spring 42. Thus seal 39 on closure member 13 moves away from its seat 38 and exhaust port 11 is subsequently closed by the member 13, whereafter a flange 55 prevents the closure member 45 from further rightward movement so that the continued movement of the member 13 causes opening of port 49 and connection of the compressor with the load. The seal 39 co-operates with its seat 38 when the valve is in the unloading position to prevent backflow from the load. When the valve is used with a reciprocating compressor, the air in chamber 19 damps the consequent reciprocating movement of the closure member 13.

Abstract: 679,341. Partly electromagnetic switches. YOUNG, I. F., and CLEMENTS, V. A. H. March 19, 1951. No. 5349/51. Class 38 (v). When a predetermined maximum demand is exceeded a solenoid i attracts its core r against the action of an adjustable spring t thereby breaking at k an "off-peak circuit" including pieces of apparatus whose services can be dispensed with ; the core is locked in this position by a pin g entering a hole h until released later by hand. Adjustment is by a knob e which when turned alters the compression of the spring t, and also moves an indicating finger b which indicates the size of the maximum load permitted.

Abstract: 1,195,162. Amplifying circuits. NATIONAL RESEARCH DEVELOPMENT CORP. 13 Feb., 1969 [2 Feb., 1968], No. 5476/68. Heading H3T. Overload effects in an amplifier which comprises a capacitor 15, Fig. 1, coupling two stages 13, 14 are reduced by means of a switch 17 connected to allow discharge of the capacitor, and a sensing device 19, connected to detect the presence of an overload in the amplifier circuit, which operates to effect discharge of the capacitor by operation of the switch. Switch 17 may be shunted across resistor 16, which is connected between the capacitor and earth. As shown the amplifier 14 gives a balanced output to which diodes 20, 21, Fig. 2, in the sensing device are connected. The diodes 20, 21 feed into a two-stage direct-coupled amplifier comprising transistors 23, 24 having a delay bias from resistor 26 and adjustable resistor 27, followed by diode 28. The output from diode 28 is fed via a time-constant circuit 29 comprising two resistors and two capacitors, to the base of transistor 30, the collector potential of which controls the operation of switch 17, which comprises a field-effect transistor. Alternatively a reed switch may be used. The arrangement is more particularly intended for use in electrocardiographs.

Abstract: 548,913. Garment press. ARMSTRONG & CO.. Ltd., J., and FEASEY, C. E. April 30, 1941, No. 5610. [Class 138 (ii)] A garment or like press has a fixed head 3 against which a garment-carrying buck 14 can be pressed by admitting pressure fluid from a supply pipe li9 to a cylinder 6 the piston rod 8 of which carries the buck 14 and swings in a slot of the frame, having wear strips 11 on the sides and buffers 16, 17 at the ends. The cylinder head 5 has a long bearing for the rod and is formed with trunnions 4 journalled in the main frame low down so as to give swing sufficient from the rear pressing position to the front loading position. Near the trunnions the pipe 21 from the cylinder joins a pipe 20 from a lift valve 22 automatically opened by contact of the piston rod in the pressing position the valve being connected to the supply pipe 19, and the exhaust through a silencer 27, a treadle 24 serving to operate through a rod 26 a spring controlled double lift valve for shutting off either .pressure or exhaust from the valve 22.

Abstract: 672,862. Super - regenerative circuits. PHILCO CORPORATION. Feb. 28, 1947 [April 6, 1946], No. 5823/47. Class 40 (v). A super-regenerative amplifier is quenched by means of a pair of rectifiers coupled to the tuned circuit in a balanced manner such that the quench voltage which is applied to the rectifiers to render them conducting or non- conducting does not shock excite the tuned circuit. Fig. 2 shows a receiver comprising a super-regenerative amplifier valve 17 coupled to the tuned oscillatory circuit 18. Two normally conducting diodes 25, 26 each in series with a condenser 27, 28, are connected in opposite polarity across the tuned circuit and a rectangular quench wave is applied in push-pull manner to the junctions between the diodes and their condensers to render the diodes simultaneously non-conductive and allow the oscillation to build up in the tuned circuit. In an alternative arrangement, Fig. 1 (not shown), the cathodes of two diodes are connected to opposite ends of a coil coupled to the tuned circuit and the quench wave is applied between the anodes, which are connected together, and the centre tap of the coil in series with a condenser-resistance biasing arrangement. A condenser is connected between the anodes and centre tap to provide a path for the oscillation frequency. Specification 672,863 is referred to.

Abstract: 955,519. Electrode materials and processing. ENGLISH ELECTRIC VALVE CO. Ltd. Out. 18, 1962 [Feb. 15, 1962], No. 5845/62. Heading H1D. To prevent impairment of the secondary-electron-emitting properties of the dynodes 2 . . . 6 of an image intensifier tube during the processing of its photo-cathode 1, the glass envelope E of the tube has two pumping stems 8, 9 so that dry nitrogen may be passed through the envelope during baking, prior to the baking with the envelope evacuated which forms a step in the processing of the photo-cathode 1. Nitrogen (from a heater) is passed through the envelope for two predetermined periods at a high temperature, the second period being greater in time and temperature than the first. The temperature is then allowed to fall, the nitrogen flow is stopped and the stem 9 is sealed off, after which the envelope E is evacuated through the stem 8 without changing the temperature. The envelope is then baked for a predetermined period and finally allowed to fall to room temperature, the remainder of the photocathode processing being performed in the usual way. Typical values are given for time, temperature and gas pressure and the use of other inert gases is mentioned.
