Abstract: 332,783. Bamag-Meguin Akt.-Ges. Oct. 27, 1928, [Convention date]. Gas-producers.-In an automatic arrangement for reversing the hydraulic cylinder 2 of the stop valve 1 of an intermittent, gas producer, in which a continuously revolving shaft 18 effects the reversal in a definite serial order, the movable jet tube 13, which terminates in a nozzle 14 and conveys the fluid pressure medium, is brought by means of levers 19, 20, coacting with cams on the control shaft 18, into the two end positions for admitting the pressure medium to the ends of the control piston 12. In the position shown, the space between the heads of the piston 12 puts the upper part of the cylinder 2 into communication with a pressure accumulator 6, fed by a pump 10, through pipes 4 and 7, thereby closing the valve 1. When the piston 12 is moved to the bottom of its cylinder on the reversal of the jet tube 13, 14, the fluid above the piston 2a escapes to the return fluid tank 9 whilst pressure fluid from the accumulator passes through pipe 5 to the cylinder 2 to raise the piston 2<a> and open the valve 1. The jet tube 13 may be of a springy nature and coiled as shown, and communicates with the pressure accumulator 6 through the pipe 16; alternatively, the jet may operate from a separate source of fluid pressure. The shaft 18 is fitted with a pair of stepped cams 17 operating through levers 19, 20 and suspended links 22, 23 to move the jet tube alternately to its end positions, these being located by stops 27, 28.

A nuclear reactor with a cylindrical core including a moderator of solid material formed with ducts extending parallel to the longitudinal axis of the core and serving to contain fuel elements and to conduct fluid coolant, is provided with coolant directing means arranged to direct the coolant in a manner tending to maintain the sheaths of all the fuel elements at approximately the same temperature. In one arrangement, Fig. 4, baffles 9, 11 are arranged adjacent the end faces of the moderator block so that coolant flowing from an inlet 7 is directed radially over the inlet face of the moderator block. The baffles 9, 11 are preferably adjustable in a longitudinal direction, as by the rack and pinion devices shown. In another arrangement, Fig. 5 (not shown), coolant passes from an inlet to the centre fuel channels, and on reaching the other end of the channels is reflected by the pressure vessel into the outer channels whence it passes to an outlet located at the same end of the moderator block as the inlet. In a variant of this arrangement, Fig. 6, coolant passes from an inlet 7 through the centre channels, is deflected by a baffle 22 into the intermediate channels, and is deflected by a further baffle 21 into the outer channels and passes from them to the outlet 8. Tubes 19 pass through the surrounding pressure vessel and some of them pass through the baffle 21 to allow fuel elements to be inserted into and removed from the channels. In another arrangement, Fig. 8, two similar reactor cores 1, 1<SP>1</SP> are coaxially disposed with a coolant inlet space 23 between adjacent faces of the cores. Outwardly of the inlet space is an annular supply duct 24 formed with openings 26 uniformly distributed around its periphery and leading from the dust to the inlet space 23 so that in operation coolant enters the supply duct 24 and flows radially into the space 23 through the openings 26. Reference has been directed by the Comptroller to Specification 755,291.

Abstract: 1433253 Centrifugal separators and classifiers DONALDSON CO INC 1 June 1973 [12 June 1972] 26178/73 Heading B2P In a centrifugal separator, classifier, or scrubber or pneumatic conveying tube, a vortex is imposed upon a primary flow of particleladen gas by a vortex-forming device 20, Figs. I and 3, including an annular hub member 22 having spaced nozzles 34 leading to the periphery of the member and supplied with auxiliary gas under pressure, the nozzles being positioned to discharge jets of gas 36 whose axes lie in one or more planes generally perpendicular to the direction of primary flow and are generally tangential to the periphery of the member 22, the vortex created submitting the particles to centrifugal force thereby causing them to be separated or classified. The apparatus of Figs. 1 and 3 constitutes an air cleaner having a cylindrical housing 10, an open dirty air inlet end 11, an axially located clean air discharge tube 12 and dirt discharge tube 17 tangential to the housing and provided with a slotted automatic evacuator rubber valve 18. The annular hub member 22 forms part of a closed cylindrical casing 21 having end caps 21a, 21c and a tubular centre portion 21b. The casing 21 is mounted in the housing 10 by conduit members 24, 25. Conduit 25 is in communication with the interior of the casing and is connected to a compresor 27 which supplies air or other gas under pressure to the casing interior. The latter communicates with the nozzles 34 through L-shaped pockets 32 formed in the wall of the hub member. The nozzles 34 are formed as orifices in radially extending wall portions 33 of the hub member. Extending in a downstream direction from the innermost edge of each wall portion 33 is a ramp surface 35 that is curved in a radially increasing manner to enhance the attachment of the adjacent jet to the surface of the hub member thereby constricting the vortex created by the jets. In a modification, the dirty air inlet may be tangential to the housing 10. Fig. 8 shows a particle classifier with a vaned inlet 41 and a vortex forming device 42. Suction is applied by a blower 45 to a fine fraction outlet 46, the fine fraction being collected by a filter 47 and deposited in a container 48. The coarse 'fraction is drawn through a tangential outlet 49 by suction applied by a blower 50 and is separated by a filter 51 and deposited in a container 52. Fig. 10 discloses a reverse-flow air cleaner with an open top dirty air inlet end, a vortex forming device 56, a clean air outlet conduit 58 and a dirt collector 59. In the case of a scrubber, liquid is sprayed through the nozzles in conjunction with the air jets.

Sept. 18, 1931, No. 26212. [Classes 7 (iii), 7 (iv), and 7 (vi).] Fluid thermostatic devices provided on the engine cylinders are arranged to close the throttle, retard the ignition, or enrich the mixture when the temperature exceeds a predetermined maximum, while normal actuation of these controls is permitted at lower temperatures. If liquid of a boiling-point equal to the limiting temperature is used in the thermostatic bulbs, the vapour produced when boiling occurs will actuate the engine controls when any one of the cylinders becomes too hot. If, however, gas is used instead of liquid, the gas pressure due to one cylinder becoming hot will be equalized with the gas pressure in the bulbs of the remaining cylinders, and the controls will be affected only by the average temperature of all the cylinders. The Figure shows a radialcylinder engine provided with thermostatic bulbs 3 on the cylinders, each connected by a tube 4 to a bellows 7, the outer end of which is connected by a bell crank 9 to adjustable control rods 11, 12, 13 leading to the throttle, ignition, and mixture controls respectively.
