Abstract: 571,336. Hydraulic transmission of power. LUCIEN, R. March 24, 1943, No. 4799. [Class 69 (ii)] In a remote-control system, e.g. for operating hydraulically undercarriages &c. in aircraft, of the kind in which motor devices 11 are each operated from an accumulator 12 under control of valves 18, 19 operated hydraulically from a remote point, the valve-actuating mechanism also controls locking devices for one or both ends of movement of the jack. As shown, valves 18, 19, controlling the connection of the respective ends of the motor 11 to accumulator pressure and exhaust, are actuated by fluid pressure controlled by manually-actuated valves 41, 42 at a remote point. The valve-actuating cylinders 35 are also connected to locking cylinders 55, 56 to withdraw the respective locking bolt before the motor operates. Valves 18, 19 each comprise a lift valve 24 having a ported hollow stem 23, the end of which is closed to cut off the connection to the exhaust reservoir when a tappet 34 is moved by the pressure piston 36 to open the lift valve and thereby connect the motor cylinder end to the accumulator. Only those pipes connecting the accumulator to the motor are of large size, small diameter piping being used for the connections to the control station and supply pump 16. Specifications 425,207 and 557,525 are referred to in the Provisional Specification.

Filed: 1967-02-02
Abstract: 1,140,015. Gas turbine plants. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Feb.2, 1967, No.5130/67. Heading F1G. [Also in Division F4] In a system for processing natural gas, gas coming from a wellhead 11 is cooled by a heatexchanger 14 before passing through an expansion turbine 18 to a gas/liquid separator 21, the outlet conduit 23 of which communicates with either a rotary gas compressor 26 and pipe-line 29 or directly to the pipe-line 29 depending on whether valves 25 and 28 are open or shut, the turbine 18 being coupled with a rotary gas compressor 30 whose outlet 32 communicates, via combustion chamber 34, with a gas turbine 37 that can be coupled with either said rotary gas compressor 26 and/or a rotary electric generator 42. In operation, gas under high pressure will leave the underground reservoir and pass, via the turbine 18, to the gas/liquid separator 21, the processed gas flowing via the open valve 28 to the pipe-line 29, the energy delivered by the expansion turbine 18 to the compressor 30 serving to compress air sucked in via inlet 31, and to transport it under pressure to the chamber 34 discharging to the inlet of turbine 37, said turbine being coupled to electric generator 42. However, when the pressure has decreased, the compressor 26 is coupled to the turbine 37, and the valve 25 opened instead, the energy liberated in the turbine 18 being used to recompress the processed gas to a pressure sufficiently high to inject into the pipe-line. When the wellhead pressure has declined still further, fuel is injected into the combustion chamber 34 and ignited, thereby increasing the energy available to turbine 37. In the process, a number of wellheads 11', 11" &c. can be coupled together, whether in the same common formation or not, e.g. groups of wells at differing stages of exhaustion may be combined in a single plant in which surplus energy from one group is utilized in another group.

Abstract: 898,383. Expansion joints. TEDDINGTON AIRCRAFT CONTROLS Ltd. Feb. 13, 1961 [Feb. 15, 1960], No. 5322/60. Class 99(1). A fluid-tight expansion joint incorporates a single, flexible, metallic bellows 8 and means are provided whereby the pressure of the media carried by the pipes 1, 2 is applied to the bellows externally thereof so that the pressure on the exterior of the bellows is greater than the pressure on the interior thereof. As shown, the pipe 2 is slidable within a guide ring 5 carried by a casing 4 secured to the pipe 1, the bellows 8 being in fluid-tight connection with the ring and a further ring 9 fixed to the pipe 2. The interior of the bellows is subject to atmospheric pressure and the space between the bellows and the casing is subject to the pressure of the medium passing through the pipes. Excessive expansion of the bellows is prevented by abutment of the ends of the pipes, and excessive compression of the bellows is prevented by the abutment of interengaging, slotted guides 6, 7; the latter also prevent relative twisting motion of the pipes. The bellows may be reinforced by internal rings. Specification 889,124 is referred to.
