Title: Improvements relating to hydraulic accumulators
IPC: F15B1/10
Filed: 1945-02-09
Abstract: 588,332. Hydraulic accumulators. ELECTROL, Inc. Feb. 9, 1945, No. 3342. Convention date, March 23, 1944. [Class 69 (ii)] In a hydraulic accumulator a cylindrical receptacle 10 closed at one end contains a flexible metal bellows 12 secured within the cylinder, one of the securing members being in i the form of a sleeve 15 extending axially within the bellows 12 and provided with an opening 22 which is encircled by a resilient ring 25 ; the latter when coming into contact with the upper plate 26 of the bellows makes a liquidtight seal between the sleeve interior and the bellow space. The flexible bellows 12 move axially in and are secured at their flared end within the cylinder 10 by means of the sleeve 15 and the annular ring 14. Oil under pressure enters the bellows space through the screwed hole 22 in the upper end of the sleeve 15 compressing the air in the cylinder 10. When the pressure in the hydraulic system drops, the bellows collapse to the limit where the plate 26 is forced against the valve ring 25, trapping the remaining oil in the bellows and eliminating the possibility of complete collapse of the bellows structure.

Abstract: 1,171,492. Boilers heated by hot liquids. BABCOCK & WILCOX CO. 23 Jan., 1967 [21 Jan., 1966], No. 3377/67. Heading F4A. [Also in Division G6] A vapour generator comprises a vertically elongated pressure vessel 112 containing annular banks of U-tubes 138 through which a heating fluid, such as pressurized water, used as a coolant for a nuclear reactor (not shown), flows from annular inlet chamber 122 to central outlet chamber 124. Feedwater, from inlet pipe 172 is sprayed from distributer 174 into chamber 168 where it mixes with and causes to condense, part of the steam generated in the generating space 116, which steam enters chamber 168 through openings 176, the heated feedwater which is at substantially saturation temperature then passing through downcomer 178 to be distributed through outlets 180 over the U-tube banks 138. Steam, generated rises to the top of generating space 116, part then passing through the openings 176 to feedwater inlet chamber 168, and the remainder passing through annular passageway 154 between the wall of the vessel 112 and inner cylindrical wall member 152, to annular superheater passageway 156 formed, about the inlet ends of the U-tube banks 138, where the heating fluid is hottest, between the baffles 148, 150 and the wall of vessel 112. The superheated steam then leaves through nozzles 160. In modifications (Figs. 2 and 3) the heating fluid inlet and outlet chambers are at the top of the pressure vessel, the feedwater being supplied at the bottom, the superheating space being defined by baffles as an upper annular space (356) about the inlet limbs of the heating fluid tube banks (Fig. 3) or as an upper central space (256) about the inlet limbs, when these are formed within the outlet limbs of the annular U-tube banks (Fig. 2). In this latter case the superheated steam exits through a double-walled insulating pipe assembly (259) to an exit nozzle at the lower end of the vessel.

As shown, the arrangements 3, 3<SP>1</SP> each comprising sixteen devices 9 are guided over the film heating location by guides 6, 6<SP>1</SP>. Each device 9, Fig. 2, supports a beam 27 having an internal heating element 28 and protected by an intermittently movable polytetrafluorethylene cloth wound on rollers 29, 30. Each device 9 has two axles 14, 15 each carrying a pair of toothed wheels 16, 17 and 18, 19, Figs. 2 and 3, engaging toothed belts 20, 21 and 22, 23 of finite length extending around the respective wheels of adjacent devices 9. Each wheel 17, 19 is formed adjacent a side plate 10 with a circumferential groove 24 and an outwardly projecting portion 25, Fig. 3, which extends through an aperture in the plate 10, the aperture being shaped to correspond to the cross-section of the wheel. Rotation of the wheels 17, 19 is prevented by engagement of the teeth of these wheels in the apertures. Slight axial displacement of the wheels 17, 19 causes the grooves 24 to align with the apertures 26 and ungrooved wheels 16, 18 to be disengaged from engagement in a side plate 11 so that the wheels can be rotated to wind thereon or unwind therefrom portions of the belts 20, 21, 22, 23 to adjust the distance between successive devices 9 to alter the distance between successive seals. Curved guides 26 prevent disengagement of the belts from the wheels. Each device 9 carries a flexible rubber flap 31 the end 32 of which projects beyond the operative surface 27<SP>1</SP> of the beam 27. The flaps 31 of opposed devices 9 are deflected to the position 31<SP>1</SP> as the units encounter each other so that any tension in the film 2 at the heating location is eliminated. A perforating blade 33 is provided on each of the units 9 of one loop only to maintain the film 2 in position. Alternatively, at this location, the devices 9 of each loop may be provided with flaps similar to the flaps 21. The heated film layers are pressed together to effect sealing by two rollers 7, 7<SP>1</SP> at least one of which is cooled. In a modification, the beams on the arrangement 3<SP>1</SP> only have heating elements, the beams on the arrangement 3 acting as counter pressure elements.
