Title: Storage of gases which are in the liquid phase
Inventor: JACKSON ROBERT GLOVER
IPC: F17C3/00
Filed: 1960-08-24
Abstract: 959,328. Storing liquefied gas. SHELL RESEARCH Ltd. Aug. 22, 1961 [Aug. 24, 1960; April 25, 1961], Nos. 29901/61 and 14959/61. Divided out of 920,298. Heading F4P. A reservoir for storing liquefied natural gas comprises a hole at the surface of the ground 105 (Fig. 2) lined with porous material 103, such as cork or foamed synthetic plastic which may be retained by shuttering. The porous material is impregnated with water or heavy fuel oil which freezes around the inner surface of the porous material when the liquefied gas is added, to form an impermeable layer 102. To reduce the forces caused by hydrostatic pressure, the water or oil in the porous material may be circulated by a pump 108, being withdrawn at 109 and pumped back at 106. Alternatively, both fuel oil and water may be used to form in the porous material, proceeding from the inside of the reservoir, a layer of frozen oil, a section of circulating fuel oil, a layer of ice, and a section of circulating water. In the embodiment shown in Fig. 3, the bottom of the reservoir consists of a layer of clay 12, and porous material impregnated with water or oil forms the inclined sides 10. Cooling tubes 121 are sunk in the ground around the reservoir. The cover consists of a plate 14, a heat-insulating layer 17 and an asphalt envelope 18. The edge of the plate has a flexible portion 15, to allow for expansion, and a portion 16 extending downwardly into the porous material 10 to form a seal. The cover may be supported on beams resting on aluminium columns inside the reservoir (Fig. 4, not shown). Specification 894,762 also is referred to.

Title: Improvements in or relating to hydraulic devices for governing systems
Inventor: FIALA LADISLAV
IPC: F01K7/34
Filed: 1962-08-03
Abstract: 947,269. Fluid-pressure servomotor control systems. PRVNI BRNENSKA STROJIRNA, ZAVODY KLEMENTA GOTTWALDA, NARODNI PODNIK. Aug. 3, 1962. No. 30001/62. Heading G3P. [Also in Division F1] A hydraulic regulating device comprises a plate 15 acted upon by bellows 1, 3 or diaphragms to which controlling impulses are applied and valve members 7, 11 controlling spill openings to determine the pressures in lines 8,12, these pressures reacting on the valve members to balance the forces exerted by the bellows. The valve members 7, 11 which are suspended by spring arms, are situated downstream of restrictions 9,13 and in the embodiment shown control the operation of high-pressure and pass-out valves 10, 14, respectively, of a compound steam turbine. The bellows 1 is subject to an oil pressure which is determined by the speed of the turbine and the bellows 3 is subject to the passout pressure. The arrangement is such that a fall of turbine speed, giving rise to an increase of pressure in the bellows 1, causes increase of pressure in the lines 8, 12 to open the valves 10, 14, or an increase in demand on the pass-out steam, causing a reduction in pass-out pressure, results in an increased pressure in the line 8 to open the valve 10 and a decreased pressure in the line 12 to close the valve 14. The value at which the passout pressure is maintained can be set by an adjustable spring 4. When the output of the set falls below that necessary for pass-out the pressure in the bellows 3 will have fallen to such a value that the valve 14 will be closed and the pressure in the line 8 will cause opening of a check valve 16 so that the valve 10 is controlled directly by the speed-responsive pressure. For continuous operation without pass-out a valve 17 may be closed and the bellows 3 locked. A third force may be arranged to act on the plate 15 for turbines with double pass-out.
Patent GB-370867-A (GB)
Title: Improvements in the manufacture of cellulose ethers
IPC: C08B3/00
Filed: 1930-10-07
Abstract: Cellulose is esterified in a bath wherein instead of the whole or a part of the diluent acid generally used, there is present a low-boiling solvent of the primary ester by cellulose to be produced. The use of a low-boiling solvent, for example, methylene chloride, allows of easy control of the reaction temperature since any undue heat which may be generated is taken up in vaporizing the solvent. The solvent is readily recovered by distillation when the ester has been precipitated; for example the cellulose ester solution may be introduced into a bath of water heated to above the boiling-point of the volatile solvent used. Examples are given of the production of cellulose acetate in the presence of methylene chloride, and in one case the amount of methylene chloride used is such as to prevent the temperature of the bath going above 50 DEG  C.

Abstract: 1497476 Valves CLAYTON DEWANDRE CO Ltd 30 June 1976 [17 July 1975] 30053/75 Heading F2V Communication between an outlet 12, an inlet 4 and an exhaust outlet 13 in a governor valve, for controlling remote unloader means of a powered hydraulic system, is controlled by a ball 1 which is pressed by an adjustable loading spring 5 onto an inlet seat 2 and moved, at a predetermined system pressure, by inlet fluid acting on a piston 7 against an exhaust seat 3 to close the exhaust and allow inlet fluid to a remote pump unloader (not shown) connected to outlet 12. The piston 7 is a loose fit in its bore 8 to provide a restricted path for inlet fluid to the inlet seat orifice 6. The area of the inlet seat 2 is slightly less than the area of the piston 7 on which the system pressure acts which, in turn, is slightly less than the area of the exhaust seat 3 ensuring that the ball 1 is moved rapidly between the seats 2 and 3. A light spring 15 maintains contact between the piston 7 and ball 1.

Title: Improvements in or relating to connectors for flexible metallic pipes
IPC: F16L33/18
Filed: 1931-11-05
Abstract: 383,055. Pipe couplings. KEITH & BLACKMAN CO., Ltd., J. and KEITH, G., 27, Farringdon Avenue, London. Nov. 5, 1931, No. 30648. [Class 99 (i).] In a connector for flexible metal pipes, a muff of resilient material is fitted over a pipe and into a sheath and a shell, surrounding the muff and sheath, is connected to a tubular coupling piece in such a manner as to exercise end pressure on the sheathed muff and maintain it in gastight relationship with the coupling piece and the pipe. A flexible metallic pipe 1, Fig. 1, is passed through a closely fitting rubber &c. muff 2 surrounded by a metal sheath 3 stepped inwardly at its inner end 3<1>, and enters a socket 4 in a coupling member 5. Surrounding the sheath 3 and adapted to embrace the coupling member 5 is a metal shell 6 connectible to the coupling member by a bayonet catch 7, 8 and maintained in the engaged position by a spring 9 disposed between the stepped ends of the shell 6 and sheath 3, the end 6 of the coupling member then exerting end pressure to expand the muff 2 radially against the pipe 1. The stepped end of the sheath 3 may have an inwardly extending tongue to engage, or be formed to screw on, the pipe to prevent displacement when connection or disconnection is made and the muff may be constituted by a packing wound on the pipe. A screw connection may replace the bayonet joint, the spring 9 being dispensed with. The shell 6 may serve as a handle for operating a safety cock having a gas passage formed axially in the cock plug. An inturned tongue 17, Fig. 5, on a fixed outer casing 15 surrounding a cock body 16 is disposed in the path of a pin 18 projecting outwards from the rotatable plug 16 in which a gas passage 13 is formed axially. The outer end of the connecting shell is flanged outwardly at 19, a gap in the flange 19 allowing it to pass the tongue 17 and pin 18 when the cock is " off," the pin then engaging in a longitudinal slot in the shell. Rotation of the shell to the " on " position removes the gap from the tongue 17 which engages the underside of the flange to lock the connector to the cock. In the absence of any connector, a spring-pressed plunger 22 in the path of the pin 18 prevents rotation of the cock plug, the flange 19 of the shell 6 raising the plunger out of that path when the connector is applied to the cock. In a modification, the body of the cock is castellated and the gaps thereof allow the shell to engage the pin on the plug when the latter is in the "off" position.

Filed: 1947-11-19
Abstract: 646,297. Dartboards. WRIGHT, W. Nov. 19, 1947, No. 30717. [Class 132 (iii)] A dartboard comprises a circular core, a housing comprising a band of fixed length closely encircling the periphery of the core but circumferentially displaceable relative thereto, means associated with the band and overlying the front and back of the core to secure said band against axial displacement, and numerals spaced round the front of the core and located by said means. The band may be a metal strip, a single wire or two or more parallel wires. As shown the band 1 encircles the core and has, welded to it, strips 2 and 3 overlying the front surface, the strips 2 also overlying the back surface. All strips may overlie both surfaces. A member 9 is pivoted to a member 5, welded to the band, whose end 6 overlies the front of the core and has a claw 11 which engages the core and prevents rotation of the band. Thus the position of the band relative to the core is variable. The part 6 may have a spike to engage the front of the core. Conventional scoring numbers 13 are welded to strips 2, 3 and 6. In another example the band may be constructed with a metal strip extending diametrically across the board and with a pin in the centre piercing the centre of the core and acting as a pivot. A rubber annulus bonded to the peripheral band may partly overly the front of the core and secure the numerals or have numerals inscribed thereon. Numerals as described in Specification 646,349 may be used.
