Title: Pump control system
IPC: F04B1/26
Filed: 1969-08-28
Abstract: 1275947 Hydrostatic transmissions CESSNA AIRCRAFT CO 28 Aug 1969 [11 Sept 1968] 42851/69 Heading F2D [Also in Division G3] A displacement control valve for a swashplate pump has a flow compensating spool 35 responsive to the pressure difference across restrictor 42 acting against spring 44, and a pressure compensating spool 48 responsive to the pump delivering pressure acting, via 33, 29 and the indicated route to chamber 58, against spring 59. If the delivery pressure and/or flow rate rises above the nominal value set by spring 59 or 44, then spools 48, 35 can act alone or together to decrease displacement by connecting servo-line 34 to a chamber 29 connected to the delivery line. However, to increase displacement, i.e. to lower the pressure in line 34, both valves must shift rightwards from neutral to provide an exhaust path via 51, 31, 39, 32. The pump can supply a power steering motor 13 and a lift cylinder 14.

Abstract: 1,067,511. Radiant tubes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 30, 1964 [Oct. 30, 1963], No. 42858/63. Heading F4B. A furnace e.g. for carburizing is heated by U- shaped nickel chromium alloy radiant heating tubes 5 provided at the end of one limb with a gas burner 7 and at the end of the other limb with a heat exchanger 21 arranged to heat the combustion air to the burners by exhaust gases from the burners. The combustion air enters inlet 43 and passes into an annular space between a finned heat transfer element 31 and an inner tube 25 where it is indirectly heated by the exhaust gases passing between tube 5 and the element 31, the exhaust gases finally leaving through flue 23. At the end of the tube 31 the air passes through openings 39 and back down the inside of tube 25 to a duct 27 which conveys it to the burner end of the radiant tube. Gas enters this end through a pipe 9 and is ignited at the end of tube 11 by a pilot burner 15. The ends of the radiant tubes which project out of the furnace, Fig. 1 (not shown), are surrounded by a metal box 44 filled with thermal insulation 45.

Title: Surge controller for compressors and pumps

Filed: 1959-12-23
Abstract: 944,713. Fluid-pressure servomotor control systems. FAIRCHILD STRATOS CORPORATION. Dec. 23, 1959, No, 43659/59. Heading G3P. [Also in Division F1] A control device for relieving the pressure in a conduit, such as the discharge line of a centrifugal compressor, in the event of surge comprises two chambers 130, 131 connected to the conduit 110 by small bleed ports 136, 142 and by larger ports 132, 138 controlled by non-return valves 133, 139 which open in opposite directions. The chambers 130, 131 are also connected to a cylinder 123 on opposite sides of a piston 122. For small or slow changes in pressure in the conduit 110, the bleed ports 136, 142 maintain equal pressures in the chambers and hence equal forces on either side of the piston. In the event of a sudden rise or fall in pressure, indicative of surge, the appropriate valve 133, 139 opens causing a pressure difference in the chambers and hence on opposite sides of the piston 122 which moves to the right. Such movement of the piston results in the closing of a bleed port 117 to increase the pressure in a chamber 114 which, through a diaphragm, opens a relief valve 113. In a modification, closing of the port 117 also closes a valve in a fluid supply to the compressor driving motor to -reduce the speed prior to opening the relief valve. Specification 944,714 is referred to.

Filed: 1968-09-17
Abstract: 1284075 Magnetic storage arrangements NATIONAL RESEARCH DEVELOPMENT CORP 19 Nov 1969 [17 Sept 1968] 44203/68 Heading H3B A magnetic store comprises a matrix of thin anisotropic films 10-34, Fig. 1, on a semiconductor substrate 35, each film being of such dimensions or crystalline structure that it has a closed loop of easy magnetization in the plane of the film, while at least one semi-conductor device associated with the store is formed at least partially by the semi-conductor substrate. The films may be nickel-iron, cobalt-iron or cobalt-nickel composition, the direction of magnetic flux along the closed loop of easy magnetization in a film denoting whether a binary "1" or a binary "0" is stored. The store shown is word organized, and a pulse in a read conductor 48-52 causes a non-destructive flux change in the films associated with the conductor producing appropriate induced outputs in sense conductors 54-57. To enable an output to be induced in a sence conductor it is necessary to asymmetrically position either the read or the sense conductors, or both, with respect to that axis of symmetry of a film parallel to the conductor concerned; or by shaping the sense conductor 57, 58 as shown in Fig. 5. For writing a word a diagonal hand direction switching field is applied by coils 60, 61, this field overlapping, and terminating before, coincident write pulses applied from. circuits 41, 47 to write conductors 36-45, both conductor sets being asymmetrically positioned with respect to each film. The sense and write address circuits 41, 47, 53, 59 comprise transistors of which the semi-conductor substrate forms an integral part. Noise may be reduced by using dummy sense conductors 72, Fig. 5, arranged parallel to the sense conductors but without association with magnetic films 69, 70, the sense and dummy conductors being differentially paired. The films may be less than 100 Š thick and circular in outline so that the closed flux path is defined by the peripheral geometry, or they may have a peripheral outline and closed flux path defined by the crystalline structure such as square, rectangular or hexagonal, Fig. 2 (not shown). Printed conductors formed by deposition are used which pass under or over the films.

Abstract: 1389778 Measuring engine air-flow rate NISSAN MOTOR CO Ltd 1 Oct 1973 [6 Oct 1972] 45786/73 Heading GIN The rate of flow of air into a carburetter 10 Fig.1 of an engine is stated to be proportional to the throttle opening, when the engine is on low load e.g. idling or decelerating, and is measured by a potentiometer 16 attached to the throttle valve 14. The signal S 1  from the potentiometer slider 16a is processed in a computer 18 to provide an air-flow signal SOUT. The engine load is determined by the ratio P 2 /P 1 , where P 1 , P 2  are the pressures in the carburetter induction passageway 12 upstream and downstream respectively of the throttle valve 14. The ratio is measured by a spring-loaded diaphragm 21 subjected to the pressure P 2  on one face and atmospheric pressure equivalent to P 1  on the other face. When the ratio P 2 /P 1  exceeds a value 0.5284 the diaphragm operates switch contacts 25 to replace the potentiometer signal input to the computer 18 by a signal SOUT<SP>1</SP> obtained by another transducer.
