Title: Improvements in or relating to calculating machines
IPC: G06C11/02
Filed: 1927-07-22
Abstract: 278,642. Schubert, E. July 22, 1927. Calculating-apparatus. - The indicator drums geared with the setting-means of a cam-disc and pin-wheel machine in order to display the number set up, are mounted loosely on their spindle but are automatically coupled thereto so as to be rotated with the spindle whenever the driving handle is released for operation. The drums 3 are normally free of lugs 7 formed on a key 8 slidable in the spindle 4 geared at 6 with the main shaft 1. To release the driving handle 15 it is pulled to the right and this allows a spring- influenced link 18 to swing a pivoted arm 20 so as to slide the key along its way and place the lugs 7 in recesses 11 in the pinions 10 fast with the drums. Thus in each rotation of the main shaft the spindle and the drums also receive one or more rotations.

Title: Valve plates and methods of making them
IPC: F16K3/312
Filed: 1933-07-11
Abstract: 409,167. Valve plates. BAILEY, W. M., Magee Building, 4th Avenue, Pittsburg, U.S.A. July 11, 1933, No. 19618. [Class 135.] Valve plates for goggle and like valves are made by welding several elements, including one having a valve seating surface, together to form an integral valve structure with a raised seating surface or surfaces which may readily be machined. Parts of the structure may thus be renewed. In Fig. 4, a kidney-shaped plate 25 of rolled sheet metal with an aperture 26 in one wing, has replaceable seating rings 25<1>, 25<11>, 26<1>, 26<11> welded on both sides, these rings being mutually welded at their point of tangency. In a modification, two seating rings lying side by side in the same plane are welded at their contacting point, above and below which thinner plates are welded, one of the rings being closed in by a disc welded to it. This form is modified by replacing the closed-in ring by a disc having shallow circular recesses in both faces to form raised seating surfaces. The parts may be cast or rolled from bar or sheet stock. In all the forms, a fan-shaped plate 27, by which the valve plate is pivoted between annular seat members coaxial with the controlled pipe, stop members 24, cable-holding posts 18, and a channelled cable-guide member 23 are secured to the valve plate. When the valve is released from the seat members by the expansion of tubes 12, it may be operated through a chain 21 actuating the drum 19 of the cable 17. The seat rings are of heat-resisting metal such as chromium-iron or chromium-nickel-iron alloy.

Abstract: 594,504. Fluid-pressure servomotorcontrol systems: BRITISH THOMSONHOUSTON CO., Ltd. Aug. 1, 1945, No. 19734. Convention date, Aug. 7, 1944. [Class 135] [Also in Group XXVI] An overspeed governor comprises a flyball housing 59, Fig. 4, from which a spindle actuated by the flyballs projects into a pocket 60 of another housing connected to the first, interconnected inlet and outlet passages 12, 13, respectively, through which a speed controlling fluid can flow, and a valve 22 to control such flow; and the ends of shafts 21, 17 connected, respectively, to valve 22 and to a lever 16 acted upon by the governor spindle project into a further pocket 67 where they are 'interconnected by a lever mechanism. The invention may be applied to a gas turbine plant in which valve 22 controls a byepass from the fuel supply to the burners back to the inlet of the fuel pump. The flyball mechanism comprises two bowed springs of which one, 33, Fig. 2, is clamped to a frame 35 and the ends of the springs are connected by the flyweights. The centre part of the free spring 'acts on a spindle 15 which engages an adjustable screw 15a on a spring-loaded lever arm 16, the latter actuating a servo pilot-valve 24 through a lever arm 18, link 19, and floating lever 20. Pressure fluid controlled by valve 24 to actuate the servo piston 25 is derived from the fuel supply pipe 12 and passed through a filter 31. Valve 22 is actuated by the servo-piston through a lever 29 and the shaft 21, the latter being connected to the floating lever 20 by an eccentric pin 20a so as to provide a recentring device for the servo pilot-valve 24. The servo-piston and pilot-valve are situated underneath pocket 67.

Filed: 1947-07-25
Abstract: 641,099. Supply systems for discharge lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and CUMMING, H. W. L. July 25, 1947, No. 20150. [Class 38 (iv)] [Also in Group XL (a)] In a circuit arrangement for a high-pressure metal vapour discharge lamp, especially one to be operated intermittently, an auxiliary thermionic electrode situated closely adjacent one of the main electrodes is so connected as to bring about a discharge between it and the adjacent main electrode for the purpose of facilitating the starting of a discharge between the main electrodes, and after the lamp has been brought into a running condition the connection of the auxiliary electrode is changed so that a discharge of lower intensity than that between the main electrode takes place between the auxiliary electrode and the other main electrode and will be maintained if the circuit of the adjacent main electrode be opened. The thermionic auxiliary electrode 6 is heated through a transformer 10 whose primary is converted across the mains with the two-pole switch 11 thrown to the right and switch 4 closed. An auxiliary discharge between electrode 6 and adjacent main electrode 3 starts the main discharge between electrodes 3, 2. A choke 12 maintains electrode 6 at lower potential than main electrode 2. With switch 11 thrown to the left, a low intensity auxiliary discharge is established between electrodes 6, 2 and is maintained if switch 4 is opened to extinguish the. main discharge. Specification 573,141, [Group XL], is referred to.

Abstract: 945,401. Utilizing solar heat. K. W. WILLIAMS. Sept. 5, 1962 [June 5, 1961], No. 20175/61. Addition to 944,512. Heading F4U. [Also in Division B1] Liquid, such as brine, contained in one or more trays arranged in duct 1, is evaporated by passing a current of hot air through the duct from a heater 6. Some of the liquid vaporizes into the current of hot air. The moisture-laden air flows down duct 2 to condenser 3, and the condensate is collected in tank 4. The cool air, withdrawn from tank 4 by fan 5, is passed through one path of heat-exchanger 10 where it is heated by the hot mixture of air and vapour flowing through the other path of the heat-exchanger towards duct 2. The warm dry air leaving the top of the heat exchanger is recycled to the heater 6 via pipe 12. Where sufficient sunlight is available for solar heating, duct 1 may have a glass top so that the sun's rays are directed on to the surface of the liquid to be distilled. Alternatively, solar heat may be transferred to the air circulating in duct 1 by providing it with a metal top, the surface of which is suitably coloured to increase heat-absorption, and attaching to this metal top some internal fins around which the air in duct 1 is caused to flow.

In a pulse radar having receiving and/or transmitting radiation patterns following substantially constant and linear laws in the region about the bore-sight axis (Figs. 1a, 1b at least one further pattern is provided following a law of higher order (Fig. 1c); in the embodiments the latter is quadratic. The determination of the fine structure of compound or multiple targets is thereby rendered possible. Aerials.-In one arrangement (Fig. 3a) horns (30 1  . . .) are connected to individual waveguides (31 1  . . .) all of which are fed via directional couplers from three waveguides (32 1 , 32 2 , 32 3 ); all the horns are excited with equal amplitudes. The three radiation patterns corresponding to points (A, B, C) (Fig. 3b) on respective waveguides (32 2 , 32 3 , 32 1 ) are used to form the constant, linear and quadratic patterns (A, B - C, B + C, Fig. 3c) the latter two patterns being formed from a magic-T (33). The aerial may consist of three horns fed with unequal amplitudes (Fig. 5). In an arrangement for providing azimuthal and elevation directionfinding five radiators are disposed in a cruciform arrangement (Fig. 6). The aerial arrays may be provided with reflective or refractive focusing means. Pulse radar (Fig. 4).-The aerial output signals (A, B - C, B + C) are applied to respective amplifiers (41 2 , 42 2 , 43 2 ) at intermediate frequency; the output of one amplifier (41 3 ) is utilized for common automatic gain control and as one input to each of two coherent demodulators (42 3 , 43 3 ). The output from one demodulator (42 3 ) affords the direction of the mean centre of the target and that from the other demodulator (43 3 ) being indicative of the angular separation between closely-spaced targets. To reduce the effects of noise on the output of the latter demodulator a smoothing circuit (43 4 ), having an adjustable time constant, is added.
