Title: Improvements relating to means for distributing liquids to the surfaces of aerofoils
Inventor: TANNER DENNIS CAMERON
IPC: B64D15/16
Filed: 1964-04-10
Abstract: 1,094,372. Preventing formation of ice on aircraft. T.K.S. (AIRCRAFT DE-ICING) Ltd. April 9, 1965 [April 10, 1964], No. 14966/64. Heading B7W.

Title: Improvements in or relating to hermetically closed liquid containing systems
IPC: F25D11/02
Filed: 1953-05-29
Abstract: 725,050. Dispensing measured quantities of liquids. ELECTROLUX, Ltd. May 29, 1953 [June 17, 1952], No. 14983/53. Class 106 (5). [Also in Groups XIII and XXVIII] Relates to a continuous cycle absorption refrigerating system of the inert gas type in which absorption solution is discharged from a container 18 and supplied by a pipe 26 to the evaporators (not shown) to defrost them, the discharge being effected by heat generated by a heater 15 and conveyed to the container 18 by water contained in a pipe 14 and supplied thereto when defrosting is required. According to the invention the water is supplied to pipe 14 from a chamber 11 by causing a magnet 32 to approach a magnetic float 12 which is thus lowered to displace water from the chamber 11. The magnet is brought to operative position by actuation of a handle 35 against the action of a spring 37 and an extension 30 of the magnet support 29 engages with a catch 38. Hot absorption solution passes up pipe 26 and through pipe 27 to a high temperature evaporator, and the action of the container 18 depresses the liquid in stand-pipe 17 from level A to level C. This allows vapours expelled in the boiler to pass through pipe 28 to defrost the low temperature evaporator. As defrosting proceeds, the temperature of pipe 27 will increase and when it reaches the desired value, catch 38, which is formed as a bimetallic strip, will flex to release the extension 30, whereupon magnet 32 falls by gravity away from the chamber 11. The float rises and the water contained in the pipe 14 will ultimately evaporate therein and condense in the chamber 11. In a modification, the magnet is actuated by a push button at the front of the refrigerator cabinet. In a further modification the magnet is constituted by an electromagnet.

Title: Gas flow control apparatus
Inventor: MORLEY FREDERICK WILLIAM WALTO
IPC: F02C7/224
Filed: 1959-05-01
Abstract: 879,745. Valves. ROLLS-ROYCE Ltd. April 25, 1960 [May 1, 1959], No. 15046/59. Class 135. [Also in Group XXVI] Gas flow-control apparatus comprising a duct for the passage of hot gas (e.g. hot air) provided with two branches, has closure means for selectively blocking one or other of the branches and for simultaneously effecting unblocking of the other branch and control means, operative upon the temperature of the gas reaching a predetermined value, for ensuring that a predetermined one of said branches is blocked. The invention is described with reference to a gas-turbine plant in which hot air from the compressor or ram air is heated by being passed over hot surfaces within the engine when being employed for cooling and sealing purposes and then led through a duct 29 to a valve 24 leading through a duct 22 to a heat exchanger for heating the fuel and through a branch 26 to atmosphere. A valve gate 27 is progressively movable between a position in which it blocks the branch 26 to a position in which it blocks the branch 23. With the valve shown the total hot gas flow remains constant. The valve gate 27 is connected by a fusible plug 36 to an arm 37 splined on a shaft 38. The shaft 38 is rotated by an arm 49 connected to a temperature responsive device mounted on the fuel heat-exchanger. In operation the temperature responsive means controls the valve gate 27 so that at a predetermined low-fuel temperature the valve gate blocks the branch 26 so that hot air is supplied to the fuel heat exchanger through the branch 23. If, however, the temperature of the hot air flowing through the duct 29 rises excessively (e.g. because of a seal failure), the fusible plug 36 will melt. The valve gate 27 will then be forced by the spring 48 into the position shown in Fig. 1, in which the branch 23 is blocked. This prevents excessive vaporization of the fuel and the consequent possibility of explosion.

Title: Improvements relating to pit props
IPC: E21D15/28
Filed: 1953-05-29
Abstract: 731,217. Pit props. GERLACH, H. May 29, 1953 [May 31, 1952], No. 15094/53. Class 20 (2). In a two-part pit prop having an inner prop member adapted to be clamped against an outer prop member by one or more clamping elements in a lock, each clamping element is arranged to bear at its outer side against the prop lock and at its opposite end faces against the tightening device and the inner prop or an intermediate piece respectively, the inner side of the clamping element being free from any bearing or abutment against any parts of the prop. In Fig. 1, an inner prop member 1, which may have parallel walls as shown, or which may be of tapered form, is clamped within a lock 3 on the outer prop member 2 by means of arcuate clamping elements 4 and 5 which are stressed by means of a transverse tightening wedge 6. The outer curved surfaces of the clamping elements 4 and 5 bear against the prop lock 3. A distancepiece 7 is disposed between the clamping elements 4 and 5 and the inner prop member 1. In a modification, Fig. 2 (not shown), the clamping element 4 itself constitutes a transverse tightening wedge. The surfaces of the lock 3 which are contacted by the clamping elements may have a radius of curvature greater than that of the outer curved surfaces of the clamping elements, Fig. 5 (not shown), or they may be nearly or entirely flat as in Fig. 6, whereby a lever action results when the wedge 6 is driven home, which increases the clamping force. The wedge 6, Fig. 6, is tapered both longitudinally and transversely and co-operates with a wedge 15 having an inclined surface bearing against the lock 3, the wedge 15 being first driven in to provide a rough setting of the wedge 6 in its transverse direction, followed by driving in of the wedge 6 in its longitudinal direction.

Title: A logical circuit with two-dimensional magnetic core matrix
IPC: H03K19/16
Filed: 1966-04-05
Abstract: 1,103,717. Associative memories. GENERAL PRECISION SYSTEMS Inc. 5 April, 1966 [4 May, 1965], No. 15123/66. Heading G4C. [Also in Division H3] Matching words in an associative memory are located and read sequentially using a magnetic core storage matrix having a storage location corresponding to each word in the associative store. As shown, the storage matrix has two cores C1, C2 per location, all the cores being initially in a clear state. When a tag search is carried out outputs are produced from all the non-matching words to set the corresponding cores C1, C2. After resetting the row registers 14d, 14e, 14f, the column drivers 15a, 15b, 15c are energized to set the cores Cl corresponding to the matching words. Setting of these cores sets the corresponding row registers 14d, 14e, 14f. The column registers 15d, 15e, 15f are now reset and a row select circuit 14 selects the first of the row registers in the set state, causing the row driver 14a, 14b, 14c of the selected row to be energized to supply a half-select current to the cores C2 of the row simultaneously with a halfselect current supplied by matrix driver 50. The cores C2 corresponding to matching words are thus set, causing the corresponding column registers to be set. The first of the set column registers is then selected by column select circuit 15z, which energizes an appropriate row and column driver to restore the core C1 at the selected location to its clear state. Finally the selected column driver is energized to set the selected core C1 again, inducing an output current in the line 21a associated with it, this current being used to read out the corresponding word in the associative store. Similarly the remaining marked cores in the first marked row are selected in sequence, and the corresponding operation is repeated for the remaining marked rows of the matrix.

Title: Power operator for screw-actuated valves
IPC: F16K31/163
Filed: 1951-06-29
Abstract: 735,033. Fluid-pressure servomotor-control systems. GORDON & CO., Ltd., J., MASHEDER, H., and SCHIPPERS, J. F. Sept. 29, 1952 [June 29, 1951], No. 15543/51. Class 135. Means for operating the stem' 6, Fig. 2, of a valve comprises a rotary, reversible, fluid-operated motor 13, Fig. 1, driving a worm 7 through a clutch 114 held engaged by fluid applied to a bellows device 16, the worm meshing with a wormwheel 5 keyed to a nut engaging threads on the stem 6 whereby rotation of the motor causes axial movement of the stem. The fluid is preferably compressed air and the motor is controlled by a valve unit 20, Fig. 3, actuable by a rod 26 attached to a diaphragm or piston 22 subjected, in a chamber 21, to a control pressure applied manually or automatically from a remote point, against an adjustable spring 23. -The unit 20, Fig. 4, comprises a casing with inlet 36, exhaust ports 37, 38 and motor ports 39, 40, and valve members 28, 29 having pistons 30, 31 respectively controlled by valves 43, 44 to connect one or the other motor port to the inlet. Inlet pressure acts through orifices 34, 35 in the pistons to hold the members in the positions shown. Thus, e.g., downward movement of rod 26 opens valve 44 to exhaust chamber 42, whereupon member 29 moves to connect port 40 to the inlet. Subsequent rotation of the motor raises the stem 6 which carries a cam 45 abutting a bell-crank lever 25, which supports the spring 23, to compress the spring and re-centre rod 26. Port 40 is then cut off from the inlet and the valve stem stops in a position corresponding to the control pressure in chamber 21. In another arrangement, the piston or diaphragm acts directly on a piston valve, and the nut engaging stem 6, drives a sprocket connected by a chain to another sprocket which rotates a screw to vary the force of a loading spring on the valve. The worm may be driven by hand wheel 12 via a clutch 10 which can only be engaged when clutch 114 is disengaged by releasing the pressure on device 16.

Filed: 1925-06-18
Abstract: 237,880. Compagnie des Forges et AciÚries de la Marine et d'HomÚ- court. July 30, 1924, [Convention date]. Ordnance design; chambers; muzzle - loading. - Relates to guns having the explosion chamber and bore separated by a partition 2 pierced with an aperture adapted to be temporarily closed by a rear projection 4 on the projectile. According to the invention, the gas-pressure is regulated by allowing a part of the gases to escape through a passage 5 leading from the bore of the aperture in the partition so that the escape of the gases does not commence until the projectile has moved slightly forwards. The passage 5 is controlled by a cock 8 which may be a rotary plug, as shown, or may comprise two apertured discs. The cock may be controlled directly by hand or it may be connected to the elevating gear so that the pressure of gases may be automatically varied at different angles of elevation; for instance, the cock may be closed when the elevation is 45‹ and opened progressively as the elevation is increased or decreased. As shown in Figs. 2, 3 and 4, the cock 8 is rotated by bevel gearing the end pinion 13 of which is keyed to slide on a rod 14 mounted on a non-recoiling arm 15 pivoted to the carriage 20. The rod 14 is rotated by a pinion 23, Fig. 4, engaging lateral teeth on the range sector 16. The arm 15 carries an operating crank 17 which actuates a worm engaging the outer toothed portion of the sector 16. The sector 16 is independently adjustable, relatively to the carriage 20, about a transverse axis by means of a knob 21 which actuates a worm gearing with teeth on the inner lower part of the sector. The gun may be muzzle-loading, the projectile carrying the propelling charge as shown in Fig. 7.
