[Class 39 (i)] An electron beam valve consists of an electron gun system, a main anode and an additional electrode disposed on the side of the anode remote from the gun, the main anode and additional electrode being so constructed and arranged that by varying the cross-sectional area of the beam at the anode by varying the potential on the gun anode, the ratio of the current passing to the main anode and additional electrode may be varied, with the result that the characteristic curve plotted between the gun anode potential and the main anode current has a downwardly - sloping portion. As shown, the main anode 5 is of U -section or in the form of a narrow plate, and the additional electrode consists of a plate. The gun system consists of a directly or indirectly heated cathode, a control electrode 2, an anode 3 and a suppressor electrode 4. The electrodes 2, 3, 4 are provided with slots parallel with the cathode, so that a ribbonshaped beam is projected towards the anode 5. The valve may be used for automatic volume control by connecting the gun anode 3 with the output circuit of a detector V2, the control electrode 2 being connected with the input circuit IC. Specifications 403,973 and 455,650 are referred to.

Abstract: 502,349. Fuel-injection pumps. RAVEN, A. R. F. Sept. 13, 1937, No. 24864. [Class 102 (i)] [Also in Group XXVII] A fuel - injection pump comprises a body 1 screwed into the engine cylinder and carrying a cylinder 4 in which a plunger 11 and sleeve 12 are fitted. The sleeve 12 is loaded by a spring 19 which is stronger than the spring 30 loading a valve 23 which is fluted at 27. The plunger is pressed down by the spring 30 and fuel is drawn into chamber 13 through ports 14, An abutment 37 having grooves 38 is secured to the engine piston and strikes the plunger 11 to deliver fuel through the valve 23 into the engine cylinder.

Title: Improvements in the metallurgical treatment of copper silicate ores or products
IPC: C22B15/00
Filed: 1925-10-06
Abstract: 262,552. Dewar, W. Oct. 6, 1925. Roasting.-The copper present in ores or other products containing copper in the form of silicate is converted to oxide so that it is soluble in an ammoniacal solution or solvent in the absence of an oxidizing atmosphere by subjecting the ores &c. to a preliminary heating at a regulated temperature in an atmosphere which does not reduce the copper to the metallic state. For instance, the ore, which may contain copper oxide, carbonate, and silicate, or the silicate alone, mav be heated at 190-230‹ C. in the presence of producer gas for ¢-1 hour, or it may be heated in air or other neutral atmosphere at 500-550‹ C. for a like period, but the temperature employed and the duration of the heat treatment are dependant on the size of the particles, the percentage of copper in the ore, and its chemical nature. On leaching the treated ore with an ammoniacal solution or solvent, the copper present passes into solution without employing a current of air or oxygen. Specification 185,242 is referred to.

Title: Improvements in or relating to circuits for electric discharge lamps
IPC: H05B41/04
Filed: 1948-09-27
Abstract: 652,500. Control systems for space discharge lamps. GENERAL ELECTRIC CO., Ltd., and CATES, J. Sept. 27, 1948, No. 25138. [Class 38 (iv)] To avoid re-operation of the usual starting switch 12 included in a discharge lamp circuit, upon diminution of the supply voltage as might occur in a vehicle lighting system or with a battery source, a relay 14, 15 responsive to the lamp discharge current is included to actuate contacts 16 which duplicate the function normally performed by the starting switch, thereby holding a circuit open or closed whilst the lamp operates. The starting switch may be of the thermal type, e.g. glow discharge or resistance heated. The relay contacts are included in series with the starting switch in the preheating circuit between the lamp electrodes, the resistance heater 13 of the starting switch also being included in this part of the circuit or in series with the ballast impedance 10. The relay is preferably magnetically operated and comprises a pair of balanced coils 14, 15 which render the relay operative upon a predetermined difference of current in the coils, i.e. when the discharge starts. For series-connected lamps either a single starting switch associated with one lamp and a set of relay contacts for each lamp may be provided, or a starting switch and relay associated with each lamp. To control the magnitude of the preheating current a resistance 18 may be included in series with the starting switch to limit the preheating current, or an additional normallyclosed relay contact 19 may short-circuit all or part of the ballast impedance 10 to increase the preheating current. To obtain a high ratio of lamp voltage to supply voltage a tungsten filament lamp may be used as the ballast impedance. A condenser 17 may be included to suppress interference and improve starting. The circuit operates on A.C. or D.C. Specification 625,558 which discloses a similar arrangement is referred to.

Title: Improvements in or relating to hydraulically actuated adjustable pitch propellers
IPC: B63H3/08
Filed: 1954-08-31
Abstract: 757,461. Fluid-pressure servomotor-control systems. UNITED AIRCRAFT CORPORATION. Aug. 31, 1954 [Sept. 2, 1953], No. 25238/54. Class 135. A governing system for an hydraulicallyactuated adjustable pitch propeller comprises a propeller-actuated pump 116, a speed governor 76 controlling the flow from the pump to the propeller, a normally inactive auxiliary fluid pump 104 in parallel with the first pump, and means actuated by the governor when it reaches a predetermined off-speed position for actuating the auxiliary pump to assist the main pump. Both pumps withdraw fluid from a sump 108 and deliver it to a propeller shaft groove 92 from which it passes, under the control of the governor valve 100 to grooves 88, 94 respectively leading to the pitch increasing and decreasing sides of a piston, the groove 92 has a high-pressure relief valve 98 and a low pressure relief valve 156, the loading behind the latter being increased by fluid lead to the pitchincreasing side of the piston via shuttle valve 160. If the speed exceeds a certain value the valve 100 rises and closes a switch 351 which closes solenoid switch 313 and energizes the auxiliary pump motor 106. Another switch in parallel with 351 may be operated when the speed decreases by a certain amount to allow the auxiliary pump to assist the main pump in pitch reducing movements. The auxiliary pump may also be used for feathering and unfeathering, and reversing and unreversing the pitch. To feather the propeller the button 192 is pushed in to close contacts 194, 196, 198 and 200, the first pair of contacts energizing a holding coil 202 for the button in series with a pressure-operated cut-out switch 206. The second pair of contacts open a normally-closed solenoid feathering valve 146 and close the auxiliary pump motor switch 313. Valve 146 allows pressure via passages 92, 144 and 150 to act on piston 152 to lift the control valve 100 to pitch increasing position and close switch 351 to drive the auxiliary pump. When the propeller is feathered the pressure surge from the pitch increasing side of the piston opens the cut-out switch and permits the button 192 to return. The button is pulled to the left to unfeather the propeller, contacts 306 and 308 energizing a solenoid switch 310 which energizes the switch 313 and auxiliary motor, and also opens the normally closed solenoid reversing valve 148. When the pitch has decreased sufficiently the button is released or the circuits to the auxiliary pump motor broken when a brush 346, in series with holding coil 310, leaves a propeller contact at 314. Switches 320 and 322 are used for reversing and unreversing the pitch through valves 146, 148 and holding coils 324, 326 and 344. A manual, propeller-operated, or time control switch 356 may be opened to cut-out the auxiliary pump if the reversing operation is to be continued for a long time. A timing mechanism may be substituted for the cut-out switch 206.
