Title: Improvements in or relating to a rotary fuel pump of the kind including cam-operatedpistons
Inventor: BARNARD MARK CARY SEDGWICK
IPC: F02M59/04
Filed: 1962-08-04
Abstract: 979,730. Reciprocating pumps; gas turbine plant. ROVER CO. Ltd. July 23, 1963 [Aug. 4, 1962], No. 30120/62. Headings F1A and F1G. In a fuel pump for a gas turbine engine, having a rotor 2, Fig. 2, provided with a number of axially extending bores (not shown) containing pistons, a cam plate 6 is inclined at a fixed angle to and is (angularly) adjustable about the rotational axis to vary the angular positions of the beginning and end of the suction and discharge strokes of the pistons with respect to the arcuate inlet and outlet apertures 12, 13, and thereby to alter the effective arcuate length of the apertures, and means, operable in response to an operating condition of or affecting the engine, effect the angular adjustment of the cam plate 6. The means for effecting angular adjustment of the cam plate 6 may comprise a piston 25, Fig. 1, responsive to changes in the engine compressor delivery pressure communicated through a port 32 to a chamber 31, or an evacuated bellows, Fig. 5 (not shown), biased by a compression spring to expand with reductions in atmospheric pressure. The latter means is particularly suitable for aircraft. The resulting movement of the piston 25 or bellows moves an arm 23, secured to the cam plate supporting shaft 21, and thereby varies the angular position of the cam plate 6. The pump pistons, of which there are three, draws the fuel from the pump casing 1 through the arcuate inlet 12 and deliver it through the arcuate outlet 13 to a delivery passage 14. The outlet 13 communicates with a by-pass passage 16 which is normally closed by half-ball valves 17 carried on leaf-springs 18. At certain speeds one or both of the valves 17 will open to spill fuel to the pump casing 1. A second outlet passage 15, Fig. 4 (not shown), may be provided through which additional fuel is delivered to the engine. Alternatively, this additional fuel may be communicated to the chamber 31 in place of the compressor delivery, to control the angular adjustment of the cam plate 6 at rotational speeds below that at which a low speed governor (not shown) will open to spill the delivery from the second outlet passage to the pump inlet. This arrangement results in an increase in the arcuate length of the outlet 13 and thereby an increase in fuel flow on starting and initial acceleration of the engine. The pump may have more than two outlet passages. Specifications 819,463 and 926,937 are referred to.

Abstract: 776,643. Earth-moving apparatus. MASSEYHARRIS-FERGUSON (SALES), Ltd. Nov. 30, 1953 [Dec. 1, 1952], No. 30334/52. Class 68 (1). The means for securing a scoop 12 to frames 7, 8 attached to the hydraulically actuated draft linkage 1, 6 of a tractor are such that the scoop may be attached to the frames either in a forwardly or in a rearwardly facing position. When facing forwardly, the scoop is pivotally mounted by pins 10 on the arm 8 of each frame 7, 8 and is prevented from rotating about the pins 10, which are in front of the centre of gravity of the scoop, during filling and transporting operations by stops 19 and latch-engaged stops 18. When facing rearwardly, the scoop pivots about pins 10R and is prevented from rotating about said pins during filling and transporting operations by stops 19R and latch-engaged stops 18R. Since the depth control of the hydraulically actuated draft linkage is regulated by the compressive force acting on a plunger 4 of the hydraulic system incorporated in the tractor, the top bar 6 of the draft linkage consists of a telescopic sleeve 6A and rod 6B. When the scoop faces forwardly then the sleeve and rod are not rigidly connected and the compressive force due to the scoop digging into material is transmitted by the sleeve 6A through an adjustable abutment 6C on the rod 6B to the plunger 4. When the scoop faces rearwardly, the sleeve 6A and rod 6B are bolted together. The rod 6B is pivotally connected at 5 to a bell crank 2 pivotally secured to the tractor at 3 and to the plunger 4.

Title: Method of Making a Multi-Alkali Photo-Cathode
IPC: C23C14/24
Filed: 1967-07-05
Abstract: 1,163,499. Cathode materials and processing. RADIO CORPORATION OF AMERICA. 5 July, 1967 [6 July, 1966], No. 30871/67. Heading H1D. [Also in Division C7] A method of forming a multi-alkali photocathode comprises the steps of evaporating a layer of antimony on a substrate, e.g. of glass, co-evaporating a pair of alkali metals such as sodium and potassium from a common source over the antimony layer, and evaporating caesium on to the sodium-potassium deposit. In one example of making an evacuated photo-cell the antimony is deposited by heating a filament coated with an alloy of 40% antimony and 60% platinum until light transmission is reduced to 65%. The tube envelope is then raised to a temperature of 160-175‹ C., preferably 165‹ C., and sodium-potassium is deposited by electrically heating a channel member containing 45% zirconium, 7% potassium chromate, 7À5% hydrated sodium tungstate and 40À5% tungsten. The proportions of sodium and potassium in the mixture are such as to produce a layer having the composition Na 2 KSb, and the heating current is gradually increased in stages until the photo-sensitivity reaches a stable value; the tube is then baked for 65 minutes and the deposition resumed until the sensitivity reaches a peak value. Caesium is then evaporated in a similar way from a mixture of caesium chromate, zirconium and tungsten powder. The tube is then cooled slowly at a decreasing rate to room temperature and sealed off. In an alternative method, the sodium-potassium deposition may be carried out whilst the tube is held at a temperature of 215‹ C. As alternatives to sodiumpotassium the pairs potassium-caesium and rubidium-caesium are mentioned.
