Title: Improvements in or relating to means for reducing grid current in thermionic valve circuits
IPC: G01R19/00
Filed: 1948-06-10
Abstract: 652,799. Bridge circuits. CAMBRIDGE INSTRUMENT CO., Ltd., FULLER, P. O., and RAYNER, G. S. June 10, 1948, No. 15647. [Class 37] [Also in Group XL (c)] To reduce the flow of negative grid current in an amplifier for very small direct currents, the valve is operated with a positive potential applied to a grid interposed between the control grid and the anode, and with a negative potential applied to the anode. Then any positively charged residual gas molecules will be drawn through the open mesh grid on to the negatively biassed anode, and will not cause grid current. A short preliminary application of about 300 volts negative to the anode will cause all ions to be either adsorbed on the anode, or on the getter surface of the valve. The Figure shows a balanced pair V1, V2 used to measure small D.C. potentials. The grids 3 are fed with a positive potential from potentiometer P through resistances R1, R2, and the anodes 4, 4a are connected to a negative potential. The input voltage e to be measured is connected between control grid 2 and a suitable point on potentiometer P. Control grid 2a is connected to a tap which is adjusted to give a zero reading on galvanometer G when the input voltage is zero. When pentodes are used, .the suppressor grids are connected either to the screen grids or to the anodes.

Title: Improvements in or relating to the supply of air and gas to internal combustion engines
IPC: F02B43/00

Abstract: 531,613. Mixing air and gas; regulating. BRUSH ELECTRICAL ENGINEERING CO., Ltd., and SENIOR, H. V. July 3, 1939, No: 16367. [Classes 7 (ii) and 7 (vi)] Gas from an inlet conduit 18, 19 is admitted into the air-inlet conduit 10 past a valve 39 which is actuated by engine suction so as to have a fluttering action and cause a stratification of the air and gas charge, which renders the charge unexplosive until it is mixed by compression in the engine cylinder. Diesel engines may in this way be converted for use with gas, as the stratification prevents pre-ignition arising from the high compression ratio. The lift of the fluttering gas valve 39 is limited by a stop 45 which is adjusted by the engine governor acting through a cam 34 and lever 31, 46. Hand adjustment of the spring 43 loading the valve is also afforded by a lever 50 actuated by a screw 55 with milled head 54. The air inlet is controlled by a throttle 14 actuated by a crank 16 provided with an indicating-pointer 17. The lever 31 also carries an indicating-pointer 49, and a similar indicator may be provided in connection with the lever 50. In a modification, the governor controls a valve provided at the opening 20, and a press-button is fitted for opening the valve 39 if it should become stuck. Fig. 5 shows the valve 39 arranged vertically, with a governorcontrolled throttle 68 between it and the air conduit 10, which may be fitted with a baffle 78. The valve 39 consists of a light fibre disc closed by an adjustable spring 73, its lift being limited by an adjustable stop 75. Two such valves 39 may be arranged, one at each side of the air conduit 10, for supplying two kinds of gas. Sticking of the valve 39 may be lessened by providing it with a stem 80, Fig. 9, working loosely in a tubular member 81, the valve being guided by a wire-like extension 85 having a surrounding oil well 87. An adjustable screwed plug may be provided for the spring 84. Specifications 20964/05, [Class 7], 317,790, [Class 7 (ii)], and 482,806 are referred to.

Abstract: 1,035,925. Tractor power lift mechanisms. ROBERT BOSCH G.m.b.H. April 26, 1963 [April 27, 1962], No. 16428/63. Heading A1P. Apparatus for controlling the supply and exhaust of pressure fluid to a jack cylinder 2, for controlling the height of a plough in response to depth or tractive effort comprises a valve 39 which carries a valve member 43 and has a lug 58 to actuate a valve 54. The valve 39 has a stop 65 and a link 63, movable in response to changes in the depth or tractive force, has a stop 64. The stops engage a wedge 61 movable by a lever 60 to set the required height of the plough. Fluid pressure from a pump 18 is supplied to the valve 39 through conduits 19, 25 and 29 to a groove 37. With the valve 39 in the neutral position shown, fluid pressure flows to a groove 40, passage 41 and chamber 42 to hold the valve 43 in the position shown against a spring loading, and fluid in groove 37 can flow through apertures 49, 45 and chamber 46 to exhaust. When the valve 39 is moved to the left by the lever 60 or the link 63, the groove 40 moves past edge 35 and releases the pressure in the chamber 42. The valve 43 moves to the left under the action of the spring 44 and closes the apertures 49. The fluid pressure in groove 47 then flows through a passage and past a non-return valve 51 to a conduit 21 leading to the jack cylinder 2. When the valve 39 moves to the right from the neutral position, the lug 58 opens a valve 53 to allow fluid to flow from the jack cylinder to exhaust. Control in response to depth or tractive effort is selected by a lever 73 which positions a ring 69 concentric with or eccentric to a shaft 6 which is actuated by the jack piston. When the ring 69 is concentric, the tractive effort acts through a lever 12, lever 86, rod 84, lever 78 and rod 80 on the lever 63. When the ring 69 is eccentric to the shaft, the depth acts through lever 76, lever 78 and rod 80, the rod 84 being provided with an elongated slot 83 for a pin 82 on the lever 78. Additional controls 26, 27 may be provided for other jacks 30, 31.
