Patent GB-1256174-A (GB)
Title: Solid fuel combustion apparatus
Inventor: MCLAREN JAMES
IPC: F23C10/00
Filed: 1969-05-16
Abstract: 1,256,174. Combustion in fluidized beds. COAL INDUSTRY (PATENTS) Ltd. 5 May, 1970 [16 May, 1969], No. 25013/69. Heading F4B. Coal or coke particles are burnt whilst traversing a plurality of fluidized beds contained in a common housing. In one form, Fig. 1, the particles pass sequentially over fluidized bed forming trays 2 to 10 and back to tray 2, the trays being horizontal or inclined downwardly in the direction of particle flow and the beds being fluidized by combustion air. Pneumatic lifters (Figs. 2 and 3, not shown) raise the particles falling from the discharge end of a tray to the feed end of a succeeding tray. Fresh fuel, and/or returned fines separated from the exhaust gases leaving the housing, are fed to one or more of the lifters, which may also be provided with ash removal means. In another form, Fig. 4, superposed inclined or horizontal permeable membranes 47, 52 are used to form the beds which are fluidized by preheated air from inlet 51. Fuel from inlet 61 passes, whilst burning, over membrane 47 to well 56 to be pneumatically lifted on to membrane 52. Some ash from membrane 52 is recycled to membrane 47 the remainder discharging via outlet 62. Gases discharge through flue 63. More than one such pair of membranes may be mounted one on another in a common housing (Fig. 5, not shown), the fuel being supplied on to any one or more of the membranes. Water filled heat exchange tubes are located in the fluidized beds. Reference has been directed by the Comptroller to Specification 1,173,563.

Title: Rotary ball valve
Inventor: SANCTUARY ROBERT EUGENE
IPC: F16K5/06
Filed: 1958-08-06
Abstract: 862,189. Valves. WORCESTER VALVE CO. Inc. Aug. 6, 1958, No. 25160/58. Class 135. A valve comprises a body 10, 12 having a rotary floating valve ball disposed within a bore extending through the body and providing opposed seat ring retaining walls 18 and inlet and outlet passages on opposite sides of the ball which has a through port for alignment with these passages to open the valve, means for turning the ball including a valve stem 30 having a free-fitting connection with the ball permitting a slight downstream movement of the ball under inlet pressure, annular seat rings 20 on opposite sides of the ball having faces shaped to seat respectively against the outer surface of the ball, one of the retaining walls and a portion of the peripheral wall of the bore adjacent thereto, the valve being provided with a pressure equalizing passage independent of the inlet and outlet passages arranged to establish fluid communication between the inlet passage and the interior of the ball in the closed position to equalize the fluid pressure on opposite sides of the upstream seat ring when the pressure of the ball on this ring is reduced and fluid can pass between the ring and the adjacent retaining wall and thus escape to and through said pressure equalizing passage to the interior of the valve and thus reduce friction between the ball and the seat ring and hence the torque required to turn the ball by the stem. In the embodiment shown, the pressure equalizing passage is duplicated so that the inlet and outlet of the valve may be interchanged, the passage in either case being constituted by a number of grooves 50 across the outer peripheral face of the seat ring 20 (Fig. 2). In modifications (Figs. 6, 7 and 8, not shown) the pressure equalization passage is formed by a groove extending from end to end across the bore of the body part 10 (Fig. 6), or by a passage through the body part 10 which communicates both with the interior of the ball in closed position and with the faces of the seat rings which contact the walls 18 (Fig. 8), or by a hole through the seat ring from side to side, located near its outer peripheral face (Fig. 7). The seat rings may be made of an elastomer, including a plastic or other material such as a vulcanized rubber or a synthetic polymer such as rubber hydrochloride or a tetrafluoroethylene resin.

Abstract: 1382569 Automatic control of pressure BBC BROWN BOVERI & CO Ltd 29 May 1973 [31 May 1972] 25335/73 Heading G3R In a system for replenishing a container of a gas (SF6) which may liquify at ambient temperatures, in response to detection of its pressure dropping to a predetermined value, replenishment is prevented if a predetermined level of liquid is detected. The object is to prevent the addition of gas if the pressure drop is due to liquefaction. The container I is a buffer store associated with electrical equipment (not shown) connected to pump 3 via filter 4. Replenishment for leakage is effected from a source 5. When a solenoid valve 7 is opened by the closure of a relay 18, 19 actuated by a pressure switch 8, provided a second relay 16, 17 is closed. However, this is opened in response to a signal from a liquid detector 10 placed preferably in the bottom of the container 1. As shown the detector comprises a temperature responsive resistor in a bridge circuit, heated by the bridge current to a temperature which depends upon whether it is surrounded by gas or liquid. Alternatively it may be a capacitor in a bridge, the gas or liquid forming the dielectric, a photoelectric level detector or a float switch. The two relays comprise an AND gate.
