Title: Method of continuously vapourising and superheating liquefied cryogenic fluid
IPC: F17C9/02
Filed: 1972-04-14
Abstract: 1334977 Revaporizing gases BLACK SIVALLS & BRYSON Inc 14 April 1972 [15 April 1971] 17358/72 Heading F4P A stream of L.N.G. is drawn from a tank (12), Fig. 1 (not shown), by a pump (14) which delivers it to a heat exchanger (18) where it is vaporized by a pumped stream of ambient water, e.g. sea water, the vaporized stream 34 being then divided into two streams, one, 35, being warmed in heat exchanger 46 by the exhaust gases of a gas turbine 28, the other, 37, being warmed by the combustion air for the turbine 28 in h.e. 38 the two streams then being recombined. A regulator 39 controls the proportions of the two streams in conduits 35 and 37, the second stream also being warmed by the turbine exhaust gases in a h.e. 32. The temperature of this stream is regulated by a temperature controlled by-pass 64. The h.e. 38 comprises a series of coil banks 68, 70, 74, the warmed gas being combined with a controlled amount of L.N.G. drawn from the downstream side of the pump (14) via conduit 72, after passing through banks 68, 70. This reduces the amount of ice accumulating on the coils from the combustion air. Some of the vaporized gas output may be fed via conduit 54 to the turbine 28 as fuel. The turbine drives a generator 56 which is used to drive the pumps. In a modified apparatus. Figs. 3, 4 (not shown), h.e. 32 is omitted, and the recombined streams are fed to a mixing column (138) which is also fed with a L.N.G. stream from the downstream side of the pump (94), to form the product gas stream.

An hydraulic brake system having a vacuum suspended servomotor is provided with a wheel lock detector and an electromagnetically operated valve which is operated in the event of wheel lock to interrupt temporarily the assistance given by the servomotor. As shown in Fig. 2, the E.M. valve 35a is provided in the duct connecting the chamber 12 of the servomotor to a conventional control valve 7. On operation of the brake pedal, the plunger 27 of the valve 7 is displaced downwardly, thereby closing the internal passage in the plunger 27 and unseating valve member 32 to connect the chamber 12 to atmosphere. On detection of wheel lock, the coil of the E.M. valve 35a is automatically energized to connect the chamber 12 to the source of vacuum (e.g. the engine intake manifold). When wheel lock ceases, normal operation is resumed. In a modification, Fig. 3, a coil 41 and magnetic armature 42 are provided in the control valve 7a itself. Energization of the coil 41 due to wheel lock withdraws the plunger 27 from the valve member 35 to connect the chamber 12 to the chamber 13.

Filed: 1924-07-25
Abstract: 239,020. Evered & Co., Ltd., and Gee, A. July 25, 1924. Actuating-mechanism.-A plug valve of a gas 'lighting or heating fitting is operated by a slotted member which is linked to a spring-pressed sliding member under the control of a Bowden or like flexible cable, the mechanism being such that each successive pull on the cable effects a reversal of the valve. As shown in Fig. 1, the inner member of a Bowden cable is attached to a spring- pressed tubular member, sliding in a housing 22 on the valve body, to which is pivoted a link 19 having at its other end a pin sliding in a slotted member 17 fixed on the valve plug. Notches 17b, 17<c> are formed at the ends of the slot to receive the pin. On operation of the Bowden cable the slotted member 17 is rocked to open the valve and the spring return of the tubular member causes the pin to slide along the slot to the other notch. The next operation of the Bowden cable in a similar manner returns the slotted member and with it the valve plug to its first position. The distant control may be by means of a handle which rotates, between stope 30<e>, a plate 29, Fig. 6, having a slotted bent-over portion in the slot of which slides a pin attached to the other end of the Bowden cable. A nipple 30<c> permits adjustment of the cable. A slotted pivoted lever and a direct-pull control are also described.
