Two fluid flow control valves are actuated together each by one of a pair of opposed pistons slidable in a housing, the pistons having telescopically interengaged annular walls depending therefrom and an actuating fluid pressure being supplied to the space between the pistons to move them apart. As shown, the respective valve closure members 1 and 4 carry opposite plungers 9 and 10 extending into the housing 13 in abutting relationship with the telescopically interengaged pistons 15, 18. The actuating pressure is supplied between the pistons through a ball check valve 25 to move the closure members 1 and 4 outwardly against return springs in the valve opening and closing directions respectively, fluid pressure from the downstream side of the open valve member 1 being also communicated to the space between the pistons through a bleed 21 to hold the valves in the actuated position and permit removal of the original actuating pressure. The valves are returned to their original position by venting this holding pressure through a ball vent valve 26 which is opened by a control pressure applied to a control piston 34 of the vent valve. The ball check and vent valves and the bleed 21 may be omitted, and the actuating pressure supplied through an open inlet so that on removal of this actuating pressure the valves return to their original position.

Abstract: 1,125,525. Gas turbine electric generating set. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 15, 1967 [Aug.31, 1966], No.38949/66. Headings F1G and F1Q. [Also in Division G6] A gas turbine electric generating set for use in conjunction with a steam turbine plant has ancillary circuits so that the gas turbine set can be driven from a steam circuit of the steam turbine plant. In a steam turbine plant which includes a steam-raising nuclear reactor the gas turbine set may be started under emergency conditions by utilizing the large quantities of stored energy in the form of high temperature high pressure water and steam which are available for a considerable period after shut-down. The residual steam can be used for starting the gas turbine set either by supplying it to nozzles which direct steam on to the gas turbine rotor or to a special starter steam turbine. Normally the supply of steam would be stopped once the gas turbine set has started, but the steam supply could be maintained during operation of the gas turbine set.

Abstract: 1507229 Borehole logging TEXACO DEVELOPMENT CORP 29 Sept 1975 [24 Oct 1974] 39712/75 Heading G1N To determine the resistivity and dielectric constant of earth formations 15 in the vicinity of a borehole 13, a signal in the frequency range 10- 60 MHz preferably a 30Mhz signal is transmitted from coil 17 and received at two coils 19, 21 spaced apart along the borehole at, say, 61 cms. and 91À5 cms from the transmitter coil. The phase shift between the signals received at the two coils is measured as an indication of the formation dielectric constant by means of repective receivers 42, 43 using Schmitt triggers 46, 47 to square the input sine-waves. These squarewaves are fed to the inputs of NOR gate 48, providing an output pulse of width proportional to the phase difference between the received signals. This pulse is integrated 49 and fed to the voltage controlled oscillator 50 to frequency modulate its output signal in the range 12-13 kHz. Similarly the output signal from an automatic gain control amplifier 45, and which represents the amplitude of the signal at receiver coil 19, is fed to a VCO 51 in the range 1200- 1300 Hz. The two channels of information are fed to the surface via cable 12 and demodulated 37, 38 for feeding to recorders 24. Figure 6 indicates a combined plot of resistivity and dielectric constant whereby oil-bearing and freshwater-bearing sands may be distinguished.

A sheet or card 31 is initially advanced by a series of rollers 4a-4d (Fig. 4) in an upright position along a channel guide 3. It is then lifted vertically from the channel by a roller 17 co-operating with rollers 18 and is guided by the upper curved part 37 of the channel guide 3 and dropped on to a stack 38. A yoke 14, pivoted at (12 and 15, Fig. 4) in the machine frame (13, 16), supports the rollers (4a, 4d) and the roller 17. A pair of leaf springs 22 attached to the upper part of the yoke 14 each support a strengthening piece 23 carrying a pair of rollers 18. In operation, the yoke 14 initially takes the position shown in Fig. 1, so that a series of leaf springs 6 urge the card into engagement with the rollers 4a, 4d to advance the card 31 along the channel 3. When the card reaches the end of the channel 3 it operates a micro switch (9, Fig. 4) and energizes an electromagnet (10) to pivot the yoke 14 to the position shown in (Fig. 2). In this position the rollers 4 are moved away from the springs 6 and the roller 17 is advanced relative to the rollers 18 so that the card 31 is nipped therebetween and lifted from the channel 3. The leaf springs 22 serve also to return the yoke to its initial position, Fig. 1, when the electromagnet is de-energized. The peripheral speed of each roller 4 is greater than the speed of the preceeding roller in the direction of advance of the card 31, so that the card tends to be tensioned whilst in the channel 3.

Abstract: 1376528 Refuse bins EMERSON ELECTRIC CO 30 Aug 1972 [2 Sept 1971] 40202/72 Heading A4A [Also in Divisions B5 and B8] A kitchen trash-compactor comprises a platen 47 movable by two sets of laterally spaced lazy tongs between a retracted position 45 above a trash loading space 51 and a compacting position inside a container 42. The tongs are operated by a screw 84 rotated by an electric motor 87. Wheels 98 at the end of the tongs roll on the upper surface of the platen which is secured to the tongs by a link 101. The platen has bottle crushing ribs 225 and a peripheral sealing flap 103 and apron 104. A trash loading door 57 is pivoted about horizontal hinges 58 to a container removal door 53. The container has a rim 48 around which the end of a bag is folded, sloping sides fitting in the compactor, and an arm 72 which prevents actuation of the motor if the container is not correctly positioned. An arm 166 can be swung, if door 57 is closed, to lock the doors 53 and 57 and to start the motor 87. During descent of the platen the starting circuit of the motor is reversed so that on stalling of the motor due to the reaction of the compacted trash or a spring 96 located around the screw 84 the motor is reversed. Wear caps 115 on the ends of a torque arm inter-connecting the two sets of the tongs move between guides 111, 112. Rubber blocks are situated at the bottom of the guides to permit lateral movement of the tongs and screw 84 if jamming occurs. This movement of the screw releases an arm 95 which stops the motor 87. Alternatively the container 42 may be a loose fit so that jamming causes the container to move and release the switch 129.
