Title: A device for locking a rotatable shaft to a fixed body
Inventor: WYCLIFFE JOZEF PAUL
IPC: F03B3/18
Filed: 1962-03-05
Abstract: 1,020,384. Remotely controlled fastenings; clamps. ENGLISH ELECTRIC CO. Ltd. March 1, 1963 [March 5, 1962], No. 47807/64. Divided out of 1,020,383. Headings E2A and E2B. [Also in Divisions F1, F2 and G3] In a device for locking a shaft to a fixed body in which the shaft is rotatably mounted, a radiallyexpandable segmental ring coaxial with the shaft is radially contractible to lock the shaft, at least one of the inner and outer surfaces on each segment and the surface or surfaces on the shaft and fixed body which frictionally engage therewith is frusto-conical, spring means between adjacent segments bias the ring towards a radiallyexpanded position, and means move the ring towards and away from its locking position. A machine, Fig. 1, which may be operated as a pump or as a turbine (see Div. F1), is connected by a shaft 11 to a motor-generator 12 and has adjustable guide vanes 16 which, when the machine is operated as a pump, are locked in a suitable angular position by movement of a manual switch 86, Fig. 7, to the lock position to energize a solenoid 62 through a limit switch 91, Figs. 6 and 7. The solenoid shaft moves a shuttle piston (not shown) in a valve 52 to allow oil, received under pressure from a pump 68 through a receiver 67 and stop valve 66, to flow from a pipe 53 into a pipe 50, a ring pipe 49 and pipes 48 to the upper ends of the upper bearings 19 of the vanes 16. Each bearing 19 houses a piston 37, Fig. 3, which is raised by the oil pressure and causes a wedge-shaped locking ring 42, of segments separated by coil compression springs 45, to make frictional engagement with the surface 22b of a link attached to shaft 20 of vane 16. Additionally, the upward thrust of the piston 37 raises the vane 16 until a shoulder (not shown) at the lower end of shaft 20 frictionally engages the lower end of a bearing sleeve (not shown). One of the sides of the locking ring 42 may be cylindrical. Movement of the switch 86 to the unlock position causes solenoid 63 to be energized through the then closed limit switch 92 so that the valve 52 connects the oil delivery pipe 53 to a pipe 54 leading to a sump 69. This allows the piston 37, assisted by a ring 40 loaded by compression springs 41 and restrained by tabs 39, to return to its lower position. The locking device may be associated with a butterfly valve to prevent vibration.

Filed: 1976-11-19
Abstract: 1535797 Regenerating catalyst TEXACO DEVELOPMENT CORP 19 Nov 1976 [7 May 1976 (2)] 48243/76 Heading B1F [Also in Divisions C4 and C5] Granular zeolite catalyst which has been used for cracking hydrocarbons and is consequently contaminated with up to 2% coke is regenerated by burning the coke off in the apparatus shown. Catalyst enters through pipe 103 and is fluidised in the lower part of frusto-conical section 101 by air or other oxygen-containing gas delivered through perforate thimble 105 to create a fluidised bed temperature of 1050-1400‹F. Gas and catalyst overflows from the top of the bed down duct 106, the catalyst is returned to the cracking plant by valve 110 and the gas flows up line 69. A proportion of the catalyst is entrained by the gas and carried out of the bed to the upper part of section 101 of the vessel, where an annular distributor 112 introduces more oxygen-containing gas (equal in oxygen content to up to 10% of the flow from thimble 105) to convert residual CO to CO 2 . The reaction heat is absorbed by the catalyst, most of which falls directly back to the bed while the rest is separated from the gas discharged at 117 by one or more cyclones 113 and returned by line(s) 114 to the bottom of the bed. The catalyst may be exposed to steam to remove residual hydrocarbons before entering pipe 103.

Title: Rectifying apparatus
IPC: H01L25/03
Filed: 1968-10-11
Abstract: 1,243,363. Semi-conductor rectifier assemblies. SIEMENS A.G. 11 Oct., 1968 [12 Jan., 1968; 7 Aug., 1968], No. 48430/68. Heading H1K. A rectifier assembly has an aluminium bus frame 1 for interconnecting a plurality of adjacent semi-conductor components, one of which, 2, only is shown. As described, the frame is a part-annulus so that its side walls 11, 12 are arcuate. Three diodes are mounted on the frame to form half of a 3-phase bridge rectifier, the frame being mounted with a similar but oppositely poled assembly on the bearing plate of an alternator. An apertured spring steel strip 5 is provided between the side walls 11, 12 at the location of each semi-conductor component and presses on the component through an insulating body 4 and head 32 of a connector 31 to hold it in an individual seating 13 in the base of the frame. The component 2 may have a silicon wafer containing one or more PN junctions and held in pressure contact between the end-plates 21, 22 of its housing. A resilient insulating jacket (not shown) may surround each component to be held under slight pressure between the base of the frame and the connection head on the insulating body. If these end-plates are planar the contacting face of connector head 32 should be convex; if one of the end-plates is convex the connector head may be planar. The contacting surfaces may be coated with zinc, nickel or silver. The shoulder on the insulating body 4 has a spherical surface so that with a generally similar part of the spring a universal joint action is produced to give even pressure. To replace a component 2 the spring strip 5 may be rotated about its central aperture until its ends clear the shoulders 111, 112 on the side walls-it can then be lifted clear. These shoulders are localized and have curved surfaces co-operating with dished ends of the spring strip to give positive location to the spring when the assembly is in use. In a variant plane ends of the spring strip fit into grooves in the side walls and are locked there by shearing pieces of the side walls and bending them over as locking lugs. Components are removed by levering against the spring, with a plier-like tool. It is also suggested that the insulating body may be replaced by an insulating coating on the spring.
