Title: Improvements relating to liquid fuel regulating means for prime movers
Inventor: HARRIS THOMAS ALFRED
IPC: F02D1/02
Filed: 1950-03-07
Abstract: 701,096. Gas turbine plant. LUCAS, Ltd., J. April 18, 1951 [March 7, 1950], No. 5696/50. Class 110 (3). [Also in Group XXIX] Means for regulating the supply of liquid fuel to a jet-propulsion engine, gas turbine or like prime mover comprises a hollow body part f divided into two compartments by a partition, such as the flexible diaphragm m (or a piston) which operates a liquid jet diverting or interrupting means in one of the compartments, the last-mentioned means being associated with a pair of motive liquid passages i leading to opposite ends of a servocylinder a and the outflow of partition actuating liquid from the other compartment being controlled by at least one normally open valve actuated by means responsive to a variable condition such as speed, blower air pressure &c. In Fig. 1 the spring-loaded servopiston b adjusts the obliquity of the swash-plate e of a fuel pump. Alternatively it may adjust a throttle or other fuel control means between the pump and the combustion chamber of the prime mover..The hollow body part f houses a pivoted jet pipe g supplied by a passage h from the pump delivery and actuated by a spring- loaded diaphragm m. The compartment containing the jet pipe is connected to a sump or the pump inlet by a restricted passage p and the other compartment is connected by another restricted passage o to the pump delivery. The latter compartment is also connected with a sump or with the pump inlet by a passage q under the control of one or more normally-open valves arranged in series so that when one or more of such valves are closed, the jet pipe g is moved to supply liquid to the left-hand side of the servo-piston and so reduce the fuel supply. Three such normally-open valves are shown. The first comprises a closure member s carried by a lever r actuated by a spring-loaded diaphragm 2. The chamber below the diaphragm 2 is supplied by a radial passage 6 in the rotating pump body 5 with fuel at a pressure related to the speed of the pump. The second normally-open valve comprises a closure member 12 on a spring- loaded lever 13 also loaded by a plunger 21 subject to pump delivery pressure, by an evacuated capsule 18 and by capsule 19 open to the atmosphere at 20. The third normally-open valve comprises a closure member 30 on a spring-loaded lever 29, actuated by pump delivery pressure acting on a plunger 32 and by the blower air pressure acting on a diaphragm 33 connected by a shackle 34 to an evacuated capsule 35. In a modification the ends of the passages are in alignment and liquid supplied directly to one side of the servo-piston from the pump delivery is diverted more or less in its passage' to the other side of the servo-piston by a pivoted shutter operating between the ends of the passages and connected to the diaphragm m.

Title: Improvements in or relating to devices for supporting photographic roll films duringdeveloping or like operations
IPC: G03D13/14
Filed: 1945-03-12
Abstract: 597,894. Photographic roll-film processing apparatus. BRADSHAW, T., and BROWN & CO., Ltd., N. March 12, 1945, No. 6130. [Class 98 (ii)] A spool for supporting roll films during processing, of the kind provided with side flanges having spiral channels on their opposed faces for receiving the edges of a film and supporting it in a spirally wound condition, is characterised in that each flange face carries two or more convolute spiral film-supporting channels. As shown, the spool comprises a hub 1 carrying a fixed flange 2 and a sleeve 3, having a fixed flange 4, slidable upon the hub. The flange faces carry two convolute spiral channels 10, 11 formed between spiral walls provided with projections 14 which prevent the film making surface contact with the walls. Openings 15 in the flanges allow free access of the processing fluid to the channels. The entrances 12, 13 to the channels are disposed diametrically opposite each other on the flange peripheries. Registration of the two sets of spiral channels is maintained by means of a slot 8 on the hub 1 receiving a projection 9 on the sleeve 3. The sleeve is longitudinally slotted at 7, each section carrying an internal arcuate rib 6 adapted to enter with snap-action a peripheral groove 5 on the hub to lock the parts together. A number of such grooves may be spaced apart on the hub to enable the spool to be used with films of different widths. The loaded spool is rotatably mounted with axis horizontal, in a semi-cylindrical tank, and may be driven by a hand wheel mounted on a spindle slidable axially to permit disengagement of drive. A two-flanged spool carrying four films spirally interleaved is described, and spool modifications are mentioned employing three or more flanges, viz. one or more intermediate flanges each spirally channelled on both faces and adjustably attached to a hub, and two outer flanges channelled on the inner face and attached to sleeve-pieces which may adjustably engage the hub.

Title: Profile milling machine
Inventor: ROHLFS JOHN H
IPC: B23Q11/00
Filed: 1959-02-24
Abstract: 918,101. Copy-milling. McKAY MACHINE CO. Feb. 24, 1959, No. 6257/59. Class 83 (3). A machine tool comprises means for relatively moving a rotary tool 26 and work clamping means 74, 75 to machine the periphery of a workpiece. The mounting and driving means for a milling cutter 26 are enclosed by cylindrical casings 10, 12 having access doors 27. The cutter projects vertically from the face of a work-table 18 and is rotated by a variable speed motor 51 driving through a belt 52 and a flexible shaft 53. The cutter spindle 50 is carried by a slide 41 movable in guides on a plate 31 rotatable in bearings 29 by a variable speed motor 35 driving through chain gearing 36 and worm gearing 34. The slide 41 carries an adjustable follower 60 held against a cam 62 by springs 63 so that the cutter follows a predetermined path on a reduced scale. If an arcuate path is desired, the slide 41 can be locked in an off-centre position by an adjustable linkage 66 which is normally disconnected. The work-holder comprises a jaw 74 adjusted against springs 82 by a graduated screw device 79, and locked by a wing-nut 83. The other jaw 75 is operated by a toggle-linkage 86 actuated by fluid-pressure means controlled by a hand-lever. During cutting, the operator has one hand on the lever and the other depresses a motor-start button, thus preventing him from injury by the cutter. To enable the minimum amount of materal to be removed from a workpiece, a stepped gauge 99 is rotated by a knurled grip 101 so that a scale 102 denotes the maximum depth of material to be removed. A bar 94 is then advanced until a stop 98 thereon engages the set gauge step, and the end of the work is pushed, with the help of a spring-pressed rod 109, against a stop-pin projecting from the bar 94. Chips fall into a tray 113 and are drawn downwardly by suction created by vanes 117 and pass through guides 115, 116 to a bin. The motors 35, 51 may be controlled by switches 119 actuated by dogs carried by the plate 31 to determine its angle of rotation and to return it to its initial position when cutting is complete. The vice may be mounted above the table to enable the cutter to swing through 360 degrees. The height of the milling-cutter may be varied during its swing.

Abstract: 303,822. Arendt, O. Jan. 10, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Gases and vapours, treating electrically.- Reactions between gases or vapours and solids are effected by high-frequency currents by producing a cloud of dust particles between the high-frequency electrodes, the dust particles producing spark fields for the " working current." In an example shown in Fig. 1, the gases to be treated are introduced by a. pipe. 11 into a reaction chamber 1 in which are mounted high-frequency electrodes 9, 10, the electrodes being provided with inwardly directed pointed projections. Situated between these are the "working current" electrodes 7, 8 which are of sieve-like form. Dust may be introduced with the gas at the pipe 11 but in the example dust-fine iron. or iron oxide falls from a hopper 16 and is delivered to the reaction chamber through a nozzle 15 by a blower 14 by means of gas drawn from the delivery pipe 12, the dust passing between the electrodes and falling into a hopper 18. In a modification, the dust is delivered to a blower situated at the base of the hopper 18 and, after passing through the electrodes, is separated from the gas current and returned to the blower. In a second modification, insulating bodies 24, which may be of the form shown in Fig. 4, are inserted between the " working current " electrodes 7, 8 and may be separated by insulating material 23, the whole being contained in a tube 22. The high-frequency field is produced by a. wire 21 wound round the tube, and the bodies 24 may be replaced by metal filings or chips. An " auxiliary gas or vapour " or a gas for cooling purposes may be introduced into the reaction chamber. The process is stated to be employed in the formation of compounds of nitrogen and phosphorus, the formation of complex bodies from carbon monoxide and hydrogen, steam or methane, the condensationof isoprene, and the synthesis of ammonia.
