Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1927-04-21
Abstract: 272,460. Westinghouse Brake &. Saxby Signal Co., Ltd., (Assignees of Farmer, C. C.). June 11, 1926, [Convention date]. Fluid-pressure. - In brake apparatus of the kind comprising a valve device adapted to maintain the brake pipe pressure at the value to which it has been reduced to effect an application of the brakes, the driver's brake valve is adapted to be set in a position in which the pressure maintaining device is operative and also in a lap position in which it is inoperative, so that equipment not. requiring the pressure maintaining action may be included in a train with equipment of the pressure maintaining type. The pressure maintaining device comprises a diaphragm 14 subject on its upper side to the pressure in the equalizing reservoir 17 and on its lower face to that in the brake pipe 1 through a non-return valve 20. The diaphragm actuates a valve 21 controlling the connection of the brakepipe 1 with a pipe 23 through which and the driver's valve air from the main reservoir 3 may be supplied. In running conditions the main reservoir 3 is connected through the usual feed valve 24, passages 25, and the rotary valve 6 to the brake pipe 1, to the chamber 10 of the equalizing valve 8, 13, by passage 11 and thence to the equalizing reservoir 17 by the passage 12. To make an application of the brakes, the rotary valve 6 is turned to connect the chamber 10 and equalizing reservoir 17 to exhaust and the brake pipe is exhausted to a corresponding extent by the equalizing valve 8, 13. The valve may then be moved to the brake pipe pressure maintaining position shown in Fig. 1 in which the reservoir 17 and chamber 10 are closed at the reduced pressure and the passage 23 leading to the maintaining valve casing is connected to the main reservoir 3 through the passage 26 in the rotary valve 6 and the chamber 5 of that valve. If then the brake-pipe pressure should fall the valve 21 is opened by the diaphragm 14 and air from the main reservoir is supplied to the brake pipe. The valve 6 may however also be moved to a lap position, Fig. 2, in which the equalizing reservoir remains in communication with the chamber 10 by passages 16, 27 while the passage 23 is cut off from the main reservoir and may as shown be connected to the brake-pipe 1 through a cavity 28.

Title: Vertical take-off aircraft
IPC: B64C39/00
Filed: 1960-03-26
Abstract: 909,466. Vertical take-off aircraft. LESLIE, T. Feb. 9, 1961 [March 26, 1960; June 13, 1960], Nos. 10761/60 and 20633/60. Class 4. Means for vertical take-off and landing of aircraft comprises a vertically-disposed jet propulsion engine 1 and an outwardly flared annular duct 7 ducting the jet radially to one or more annular aerofoils so as to produce lift, engine 1, duct 7 and the annular aerofoils being contained in a well 42 in the aircraft fuselage 6, well 42 being flared at the top. Engine 1 is mounted in well 42 by braces 2, 3, 4 and 5, which also act as fuel tanks, and the exhaust gases therefrom, issuing from an annular nozzle, together with air sucked down well 42 and drawn in from beneath the aircraft, flow over annular aerofoils 8 to 12 which are arranged concentrically around the annular duct orifice in stepped formation. A collector 22 receives the flow of air leaving the aerofoils, and ducts 35, 36 lead the flow to control fins 23 to 28, which may be individually moved away from the orifices from which the air issues. To maintain an even flow from collector 22 regardless of the attitude of the control fins, there is provided an equaliser 29 which diverts part of the flow to an auxiliary propulsion jet 30, below which is mounted a jet propulsion engine to provide forward thrust. The flow in equaliser 29 may be controlled by valves 31, 32. Control of the aircraft is determined by adjusting a rudder 33 located in auxiliary propulsion jet 30 and/or by varying the lift due to the flow over the control fins, which lift depends on the position of the control fins relative to the duct orifices.

Title: Apparatus for measuring the load on a flexible inflated body
IPC: G01G19/02
Filed: 1943-07-02
Abstract: 575,680. Weighing. GIBBS, B. J., LLOYD, R. G., and MORGAN, F. W. July 2, 1943, No. 10769. [Class 40 (i)] [Also in Groups XVIII and XIX] The load supported by a tyre a is determined by measuring the area of contact of the tyre with a support and multiplying this by the tyre pressure, a correction being applied to compensate' for tyre-wall rigidity. The contact area is measured by resting the tyre on a pad having a rubber diaphragm d provided with a metal coating d<1> which, with a sheet of dielectric e and a metal plate c', forms a condenser of capacity depending on the contact area. The condenser is connected at a point b in a bridge circuit, Fig. 2, which also contains a resistance f varied by a Bourdon gauge in accordance with the tyre pressure. The bridge is balanced by a variable condenser h or h' calibrated in loads with allowance made for corrections for tyre-wall rigidity, the balance indicator being a cathode-ray device k. In a modification, the tyre is caused to rest on a pad carrying a plurality of electric contacts. Those covered by the contact area are closed and the number so closed is automatically counted and transmitted to one element of a logarithmic computer. Another element of the computer is controlled by the tyre pressure and a third element gives the required load. An inflated bag may be inserted between the tyre and the measuring device. The Bourdon tube is then connected to the bag instead of to the tyre.

Title: Method for producing castings
IPC: B22D19/00
Filed: 1960-03-28
Abstract: 894,233. Casting composite articles. NATIONAL LEAD CO. March 28, 1960 [May 7, 1959], No. 10841/60. Class 83 (1). [Also in Group XXVII] A composite casting is made by casting under pressure into a die cavity part at least of which is lined with a coating material having an irregular surface with which the cast metal is forced into interlocking mechanical relationship. An I.C.E. cylinder liner is made by diecasting aluminium alloy 30 around a core having a sprayed-on stainless-steel coating. The alloy is cast at 4000-10,000 p.p.s.i. and interlocks with the coating, which remains with the casting as the coating 26 on removal from the die. The core is made without taper and the casting is removed by heating it quickly while the core remains cool. Since the cylinder liner is subjected to unequal wear, &c. at different parts, a continuous coating of annular bands of different materials of different thicknesses can be deposited on the core, e.g. stainless steel, ceramics, cermets, for severe conditions, molybdenum at positions of greatest wear, and steel for the remainder. The coating may be applied to the die by dipping or brushing &c. and a smooth coating may be roughened by machining. The application of the invention to engine blocks, wheels, cooking utensils, electric irons, and bearings is referred to.

Abstract: 986,528. Parametric amplifiers. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 27, 1962 [March 31, 1961], No. 11616/62. Heading H3B. A parametric amplifier comprises a transmission line 34 for transmitting signal energy, and two resonant circuits 45 and 71 coupled at spaced positions to the transmission line 34 so as to impart directional transmission characteristics, the circuits being tuned to the signal frequency and each including a variable reactance element such as 52, the reactance of which is varied by a pumping frequency higher than the signal frequency. As shown, a coaxial line 34 transmits the signal frequency and another coaxial line 40 transmits a pump frequency which is preferably twice the signal frequency. Both lines 34 and 40 are coupled to two resonating sections of coaxial line 45, 71 which are closed by end plates 52, 54, 74, 76 connecting the outer conductor to non-linear capacitance diodes connected to the inner conductors. The pump wave is capacitively coupled to the resonating sections 45 and 71 at a node of the standing signal wave and the signal wave is directly coupled at a node of the standing pumping wave (Fig. 4, not shown). The spacing of the coupling points to the signal and pumping lines 34, 40 is # of the signal wavelength so as to give a unit gain to signals travelling in the reverse direction. Strip conductors may be used instead of the coaxial lines 34 and 40 and more resonating circuits may be added. The pump wave may also be fed independently to each resonating circuit (Fig. 5, not shown). Specification 884,325 is referred to.

Title: An improved method for the production of trunk communication electric cables preferably for four-wire operation
IPC: H01B13/02
Filed: 1935-04-15
Abstract: 455,286. Cables. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. April 15, 1935, No. 11657. Convention date, April 25, 1934. Drawings to Specification. [Class 36] In the manufacture of a multi-layer trunk communication cable the partially formed cable core on to which a layer of cores is to be stranded is carried, prior to the application thereto of the layer of cores, through a device which grips the partially formed core and rotates it into a predetermined position with respect to the cores of the layer to be applied so as to bring selected cores of the partially formed core and of the layer to be applied into predetermined relative positions. The invention is particularly applicable in the production of cables for four wire operation in which the cores of like speech direction are arranged in bundles extending through several layers of cores and wherein the bundles are screened from one another by separator cores which must be arranged accurately over one another. The cable may be made on a machine having the same number of standing cages as the number of layers of cores required in the cable, so that the cable is made in one working operation, each cage being provided with rubber rollers or caterpillar traction devices by means of which the partially formed core stranded from the preceding cages may be rotated into a position such that the separator cores of the layer of cores being applied are stranded directly over the separator cores of the previously applied layers. The means for rotating the partially formed core may be operated by hand or automatically by guiding elements which engage between the cores of the layer being applied. Open or closed screens, or rough bands or cords adapted to increase friction between the layers, may be inserted between the layers of cores, in which case the position of the separator or other marking cores is indicated after the application of the screens or bands by a colour imprinting device. The layers or the separator cores may be cemented in position.
