Title: Improvements relating to gas turbine shaft bearing and sealing assemblies
IPC: F01D11/00
Filed: 1956-05-17
Abstract: 791,934. Stuffing-box substitutes. GENERAL MOTORS CORPORATION. May 17, 1956 [May 31, 1955], No. 15394/56. Class 122 (5). A gas turbine shaft bearing and sealing assembly comprises a casing 22 having at its inner periphery a cylindrical cage 30 housing a sleeve 40 supported by the cage for axial movement but prevented from rotation and carrying a seal ring 41 urged by spring means 48 between the sleeve and the cage into sealing contact with a metal seal ring 19 fixed to the shaft 10. The casing 22 comprises inner and outer plates 26 and 27 separated by heat insulating material 28 and the space 37 between the casing and the first turbine wheel 11 is subjected to compressed air derived from the combustion chamber. The sleeve 40 is sealed to the cage by a piston-ring 42 housed in a groove 52 in the sleeve and bevelled, as at 54, Fig. 5, at its outer periphery to reduce the radially outward pressure on the cage due to the compressed air acting behind the ring. Ribs 46 on the interior of the cage engage notches in radial arms 45 on the sleeve 40. The carbon seal ring 41 is recessed at 56 and urged into sealing contact with the ring 19 both by the spring 48 and the air pressure differential across the sleeve which is located between the ring 19 and a flange 51 of a spacer ring 50 secured to the shaft. If relative movement, between the shaft and the cage, due, for example, to expansion when starting the turbine, tends to move the ring 19 away from the ring 41 and, due to the sleeve 40 sticking in the bore 43 of the cage, the rings are no longer in contact, the sleeve is urged towards the ring 19 either by the air pressure build-up between the flange 51 and the end of the sleeve or, if that is insufficient, by direct contact between the flange and the sleeve. The bearing 14 and the seal are lubricated, and the seal is cooled, by oil supplied through a hollow tie-bolt 60 passing through the shaft 10. The oil passes through a spacer 62, a radial passage 63 in the shaft to a groove 64 in the ring 19 whence it is distributed by passages and ports in the ring to the bearing, the face of the carbon ring 41 and the interior of the cage 40.

Title: Recovery of sulphur dioxide
IPC: C01B17/60
Filed: 1972-04-04
Abstract: 1341174 Removal of SO2 from gas streams UNITED STATES ATOMIC ENERGY COMMISSION 4 April 1972 [28 April 1971] 15500/72 Heading C1A Sulphur dioxide is recovered from a gas stream by mixing the stream with or passing it together with oxygen in an amount at least stoichiometric with respect to the SO2 and then passing the stream into a bed of reactive uranium dioxide particles at a temperature between 300 and 500 C. until the bed is saturated. An inert gas stream containing sulphur vapour may be passed into the saturated bed to regenerate the uranium dioxide and liberate sulphur dioxide. The reactive uranium dioxide is preferably made by reacting uranyl sulphate with sulphur vapour, thus the absorption and regeneration processes can be carried out in sequence using the same bed.

Abstract: 254,705. Goerz Optische Anstalt Akt- Ges., C. P. June 30, 1925, [Convention date]. Gunnery calculators-Apparatus for determining the ballistic values for laying a gun comprises means for setting the observed horizontal distance and height of target by the use of two pointers and corresponding scales, pointers connected with the setting means, and movable over a stationary time curve chart and elevation chart for indicating the fuze setting and gun elevation, and means for correcting the azimuth for the drift of the projectile. As shown in Figs. 1 and 2 a frame 1 mounted on the gun carriage or on a separate support carries a shaft 2a to which is fixed a bevel wheel 2 forming one element of a differential gear 2, 3, 4, 4<1>, the wheel 3 being loosely mounted on the shaft 2a and the pinions 4, 4<1> being carried by a disc 5a also freely mounted on the shaft 2a. The disc 5a is provided on its circumference with helical teeth engaging a worm 8 on a screw spindle 7 operated by a handwheel 9 for setting the height of the target by a pointer 30 on the scale 28, the pointer being formed on an arm 10 engaging the spindle 7 and a guided rod 11. Journaled in the arm 10 are two screwed spindles 12, 13 rotated in opposite directions by gearing 14, 14<1> from a handwheel 15; the spindle 12 is provided with nuts 16, 17 arranged to move in opposite directions by reason of the provision of right- and left-handed screwed portions, and the spindle 13 is provided with a nut 18. The nut 16 has two pointers 16a and 20 for setting the horizontal range on a scale 19 on the arm 10 and for indicating on the fixed chart 29 the fuze time respectively. The nut 17 has a pointer 21 co-operating with the polar curves of equal elevation of the target on a plate 30 carried by the bevel wheel 3 of the differential gear. The plate 30 is set by the worm c and the shaft 2<a> is rotated to keep the pointer 21 on the target elevation line, and the movement is conveyed to a pointer or transmitted direct to the gun to give it the required elevation. The nut 18 on the spindle 13 is provided with a pin 18<a> engaging a slotted arm 22 of a toothed quadrant 23 rotatably mounted on the shaft 2a and engaging a pinion 25 loose on a shaft 32 ; a second pinion 26 loose on this shaft engages teeth 24 on the rim of the bevel wheel 2. The pinions 25, 26 are connected by bevel wheels to planet pinions the shaft of which carries a pinion engaging a segmental rack carrying the pointer for giving the lateral angle of the gun. By this means the setting of the bearing angle is corrected for the drift of the projectile.

A fluid pressure actuator for producing rotary motion of an output shaft 7 comprises a casing 1 in which the shaft is journalled and which has a pair of cylinders 3 provided with a common piston 6 having a central trunnion 15 in the diametral holes of which are slidably mounted a pair of arms 11 securely pinned to the shaft 7, and valve means for supplying pressure fluid to one cylinder or the other to effect axial displacement of the piston and thereby rotational movement of the shaft. In operation a main control valve (not shown) connected to a source of pressure fluid is operated to simultaneously connect one of a pair of ports 24, 38 to the pressure fluid and the other to drain. The ports communicate with a pair of cylindrical valve blocks 19 and 20 disposed end to end within a blind hole 18 in the casing 1 and secured axially therein by a closure plug 21. A floating piston 44 is slidable in a cylindrical recess 43 in the valve block 20 and at the ends of its stroke is arranged to abut the plungers 25, 35 of a pair of normally closed spring urged poppet valves 26, 34. If pressure fluid is supplied through the port 38 the valve 34 is opened and fluid passes to the right hand cylinder, simultaneously the piston 44 opens the other valve 26 to allow fluid to be expelled from the left hand cylinder to drain. If the main valve is moved to a neutral position both poppet valves close to lock the piston. Specification 965,394 is referred to.
