Title: Production of Nitrides of Actinide Metals.
IPC: C01B21/082
Filed: 1967-05-10
Abstract: 1,188,011. Plutonium compounds; nuclear fuel. W. R. GRACE & CO. 10 May, 1967 [1 June, 1966], No. 21809/67. Headings G6C and G6R. [Also in Division C1] Actinide metal nitrides, i.e. oxynitrides, carbonitrides, carboxynitrides, or mono-, di- or trinitrides of, in particular, U, Th, Pu, are prepared by heating in an atmosphere of nitrogen either (a) the oxide of the metal in colloidal form in the presence of colloidal carbon or (b) a carbide of the metal formed by heating in an inert atmosphere in the presence of colloidal carbon the oxide of the metal in colloidal form. The actinide oxide may be in admixture with an oxide of another metal, e.g. Zr, Al, Ti, Nb, Y, Be, Ta, Mg, Si, V, W, Ce, Yb, Gd, so that mixed nitrides are obtained. The nitrides produced may be densified by heating in an inert atmosphere, e.g. a rare gas, at above 1500 C., e.g. 1800-2000 C. said atmosphere may contain a small quantity of nitrogen to counterbalance disproportionation of the nitride. Nuclear fuel may be made by coating the final product with carbon, by heating to 1000-1400 C. in an inert gas, introducing a gaseous hydrocarbon, e.g. CH 4  at that temperature, increasing the temperature to 1750-2200 C. while maintaining the hydrocarbon feed and removing the coated product.

Title: Improvements relating to flight conveyor installations
IPC: B65G19/14
Filed: 1949-08-23
Abstract: 666,038. Endless conveyers. HAPMAN, H. W. Aug. 23, 1949. No. 21854/49. Class 78 (i). A flight conveyer installation for serving a material processing apparatus comprises material loading and unloading stations, a conveyer conduit system including a supply conduit portion extending from the loading station to the inlet of the processing apparatus, an intermediate portion extending from the said inlet to the outlet of the processing apparatus, a discharge portion extending from the said outlet to the unloading station, a return portion extending from the unloading to the loading stations, and an endless flight conveyer extending through said conduit portions. Fig. 1 shows an installation for conveying material to a wet processing apparatus 11 and then conveying the processed material to a disposal station 12. Material is fed into a conduit 13 through a hopper 14 and conveyed by a flight conveyer chain 15 passing round a sprocket 16 driven through reduction gearing 18 by an electric motor 23. The chain preferably has flight discs of rubber operating in a metal pipe in the presence of water, the latter serving to lubricate the edges of the discs. The conduit 13 comprises a portion 15 leading to the inlet 25 of the apparatus 11, a portion 26 leading from this .to the outlet 27 of the apparatus 11, a portion 28 leading to the unloading station 12, and a portion 29 leading to the hopper 14. Material on reaching the inlet 25 falls into the apparatus 11 and after passing to the outlet 27 is conveyed to the station 12 along the conduit portion 28. Surplus liquid in the material conveyed along the conduit portion 28 returns along the conduit 31 to the processing apparatus 11. Material is forcibly dislodged from the chain 15 as it passes the inlet 25 by a vibrator 35 consisting of a hammer 38 carried on the free end of a spring arm 36 secured to a support 37. This hammer is moved up and down so as to hit the chain by eccentrically-mounted weights (not shown) on a shaft 39 which is journalled at 40 on the arm 36 and rotated through pulleys 41, 43 by a motor 44. Fig. 2 shows the application to a sifting process, wherein material fed into a hopper 52 is conveyed by the flight conveyer chain 61 along a conduit 51 to a conduit 55 from which it falls into a shoot 68 leading to sifting apparatus 69 comprising a screen 70 reciprocated through belt-and-pulley gearing 73, 74 by an electric motor 76. The sifted material passes down a hopper 71 to a conduit 57 where it is picked up by the chain 61 and conveyed to a discharge station 59.

Title: Controllable pitch propeller
IPC: B63H3/08
Filed: 1971-04-19
Abstract: 1341473 Variable pitch screws J M PEDERSEN 19 April 1971 [12 Feb 1970] 21856/71 Heading B7V A fluid pressure servomotor control system for adjusting the pitch of the blades 20 of a variable pitch marine screw, comprises a power output piston 39 mounted on a hollow shaft 38 housing the pilot valve spool 62 which is urged to the right by spring 69, and to the left by control pressure applied through a rotary coupling 14, the arrangement being such that upon movement of spool 62 the piston is moved to a corresponding position by power fluid which is also admitted through coupling 14. In modifications (Figs. 4, 5 and 8, 9, not shown) the spool is urged to a central position by a pair of oppositely acting compression springs and the control pressure unbalances the spool. Axial movement of the output shaft 38 is converted into rotary movement of blades 20 by a sliding cross-head 33 having inclined slots 35 which co-operate with eccentric bosses 28 on the blades. A spring 60 urges the mechanism into its full pitch forward drive position in the event of a failure of the hydraulic system. The rotary coupling comprises a stationary part provided with radial bores 94, 102, 103 and 114 which communicate via annular grooves 112 and bores in a rotary part 13 which is secured to a tail shaft 16. Thus the whole apparatus can be easily fitted to an existing vessel not originally built with a variable pitch propeller. Figs. 6, 7 and 11-13 (not shown) illustrate a number of different couplings incorporating floating seals which allow for a small degree of eccentricity in shaft 16. Fig. 15 illustrates a schematic system in which the pitch angle is indicated at a remote station by measuring the pressure inside hollow shaft 38, and the pitch is controlled automatically in accordance with engine temperature. Oil from the interior of shaft 38 is returned via bores 97, 98, 99, 56, 101 to outlet bore 103 which feeds a lubricating passage (not shown) in the tail shaft bearing.

Abstract: 1,218,954. Detecting cracks in helicopter rotor blades. UNITED AIRCRAFT CORP. 9 May, 1968 [22 May, 1967], No. 21961/68. Heading B7W. [Also in Divisions G1 and H1] Apparatus 24, mounted in a preferred embodiment in communication with the hollow interior of a pressurized helicopter rotor blade structure comprises a rigid substantially circular casing 35, having a transparent cap member 30, with spaced circumferential opaque stripes 76 thereon sealed at 60, adjacent its open end, to a base-plate member 32, having a cylindrical end portion 46, a threaded stem portion 36, conduits 164, 162, 160 recessed aperture 108 and an annular, peripheral groove 54, said baseplate 32 and said transparent cap member 30 co-operating to define a sealed chamber 34, which communicates with a hollow helicopter rotor blade 22 containing the gas whose pressure is to be monitored, via conduits 164, 160 and 162 and houses a readily replaceable, pressurized, reference capsule 90, which comprises a hollow member 92, bellows 120, positive stop cylinder 130, a fixed rigid member 100 constructed from stem portion 102, shoulder section 106 and circular plate portion 104, said capsule carrying two series of stripes 93 and 94 corresponding to said spaced stripes on transparent portion 30, and being readily detachable from recessed aperture 108, and apparatus test button and plunger mechanism 200, Fig. 7, which opens chambers 34 and 150 to the atmosphere. When operating, gas from the rotor blade 22 enters sealed chamber 34 and chamber 150, the latter being formed from members 100, 92 and bellows 120, through filter 166 and conduits 162, 160 and 164, the pressure of said gas being greater than that contained within chamber 122 of reference capsule 90 to thus cause the latter to move downwards guided by circumferentially spaced, axially extending ribs 82, by bellows 120 extending so that surface 140 of hollow member 92 abuts surface 48 of cylindrical end portion 46, Fig. 4. In this position, stripes 94 lie behind stripes 76. Reduction in gas pressure due to cracks in the blade or rupture of apparatus 24 reduces the gas pressure differential between chambers 34, 150 and chamber 122 resulting in the capsule rising through contraction of bellows 120, the movement being limited by the abutment of shoulder section 106, with positive stop cylinder 130, so causing stripes 94 to align with windows 74 (Fig. 5) to provide a visual indication to loss of pressure. Since the gas pressure in chamber 122 of replacement capsules 90 and the position of member 100 of capsule 90 relative to window member 72 is kept constant capsules 90 may be interchanged without calibration. To provide a supplementary warning in a pilot's cockpit, electrical contacts (not shown) may be installed on the capsule and on transparent casing lid 35, and/or on base 32, to operate warning lights. As an alternative to sealing device 60, 0-rings may be placed either side of a thread connection (300, Fig. 8, not shown) co-operating cap member 30 and base-plate 32.

Title: Two speed coaster brake for velocipedes
IPC: B62L5/08
Filed: 1955-07-29
Abstract: 772,396. Coaster hubs. BENDIX AVIATION CORPORATION. July 29, 1955 [Aug. 2, 1954], No. 22039/55. Class 136(2). [Also in Group XXIV] A two-speed coaster brake for velocipedes comprises a driving sprocket 38 and member 17 rigid with an exteriorly threaded sleeve 39 carrying a direct drive clutch member 41 having teeth which can be engaged with a driven clutch member 24 secured to a driven hub 19, and planet gears 27 meshing internal teeth on the member 17 and a fixed sun gear 25, the planet gears rotating on studs fast with a sleeve 16 having externally threaded engagement with a reduced drive friction clutch member 31 which can be engaged with the driven clutch member 24. A locking ball 45 in a hole in the sleeve 39 co-operates with the direct drive clutch member 41, and with a spring biassed sleeve 47 engageable by the reduced drive clutch member 31, in such a way that only one of the two clutches can be engaged at the same time. A spring drag ring 44 surrounds the direct drive clutch member 41 and frictionally engages the driven hub 19, and a spring ring 36 surrounds the reduced drive clutch member 31 and has projections 37 engaging a part rotating with the driven hub 19. In use, an operator can change from the direct drive position shown in Fig. 1 to the reduced drive position by momentarily stopping pedalling. The driving member 17 is thus stopped, but the hub 19 continues to rotate and, through the spring drag ring 44, screws the direct drive clutch member 41 out of engagement to the left. The locking ball 45 is then released so that as soon as the operator recommences pedalling, the reduced drive clutch member 31 is screwed to the left along the sleeve 16 into engagement with the driven clutch member 24. When moving to its engaged position, the reduced drive clutch member 31 engages the sleeve 47 and moves it to the left in such a position that the ball 45 is forced radially outwards to hold the direct drive clutch member 41 in its disengaged position. To reengage direct drive, the operator again stops pedalling, and preferably turns the driving member 17 slightly backwards, in order to screw the reduced drive clutch member 31 to the right and disengage it from the driven clutch member 24. The sleeve 47 is then moved by its spring to the right so that the ball 45 is released. The direct drive clutch member 41 is then free to be re-engaged with the driven clutch member 24, as soon as the operator re-commences pedalling so that it is screwed to the right. If the operator back-pedals, the reduced drive clutch member 31 is screwed to the right to engage teeth on its end with teeth 35 on an expander member 9 which is thereby forced towards an expander 4. Brake shoes 12 are thus forced outwardly against the inside surface of the surrounding hub 19.

Abstract: 599,317. Underpinning buildings; building-blocks; foundations. PRYKE, F. Aug. 29, 1945, Nos. 22279/45 and 23288/46. [Classes 20(ii) and 87(i)] [Also in Group V] Buildings are underpinned and damaged foundations &c. replaced by removing spaced small portions of the damaged part of the structure, erecting piers in the openings thus formed, which act as a shoring support during the removal of the remainder of the damaged structure, and finally passing metal reinforcing rods through aligned passages in the piers and embedding the whole-piers and reinforcementin concrete to form a new beamlike underpinning structure. The piers F are built mainly of superposed channel - section blocks A, of reinforced concrete, which may be arranged in various ways, the cross limb of the channel having a central hole A2 to act as a vent to prevent the formation of air pockets when the piers are embedded in concrete. Flat bearing plates B (with vent holes B<1> when required) are also used in the piers which may finally be made up to the required height with ordinary bricks H. The reinforcement D is passed through the channels, which extend in the direction of the wall above, and supported on rods passed through small holes A<3> in the side limbs of the blocks A. Inner and outer forms are then erected and the whole embedded in concrete, the inner form being conveniently of brick and the outer form preferably spaced slightly from the outer faces of the piers to provide an unbroken face of concrete along the length of the structure. Damaged brickwork at any height may also be replaced by the method of the invention and the final structure can then be used as a lintel and the brickwork below it removed to form a doorway &c. if desired, or the concrete may be used as an anchorage for tie bars holding the sides of the building together. The blocks A, which may also be of other material such as steel, plastic &c. of sufficient strength, may be rectangular in plan or, to safeguard against air pockets still further, of rhomb shape as shown in Fig. 11. When underpinning thick walls each pier may be built of two or more sets of blocks A side by sides, the flat plates B extending over the double &c. sets of blocks A and having when required two or more vent holes Bl.

[Also in Division B7] In an overhead conveyer comprising carriages 3 driven along a rail 1, by an endless chain 5 to which the carriages are clamped, between work stations, and having load carriers 8 suspended therefrom, each carriage 3 has a device 6 which determines at which station a load carrier 8 is to be released from the carriage 3, and each work station has a carrier-receiving device AN and a device AG for depositing a carrier 8 on a carriage 3, the devices AN, AG comprising carriersupporting bars 15<SP>1</SP>, 15 movable transversely towards and away from the rail 1. Each carriage 3 has a suspension device 7 clamped to the chain 5 and having pivotal carrier-holding bars 12, 13. The carrier-supporting bars 15<SP>1</SP>, 15 are carried by members 14 pivoted about an axle 41 secured to the rail 1. In operation, a sensing member 9 at the work station co-operates with the determining device. 6 to pivot a lever 10 so that a roller 11 on the lever abuts a part 77 of the suspension device 7 to open the holding bars 12, 13. The carrier 8 thus drops on to the bar 15<SP>1</SP> of the receiving device AN, which bar 15<SP>1</SP> pivots away from the rail 1 under the carrier weight. The carrier is later transferred to the bar 15 of the depositing device AG. A button 22 is then pressed so that, as an empty carriage passes the device AG, contacts 24, 25 are closed to activate an air cylinder 16 to pivot the member 14 such that the carrier 8 is picked up by the carriage 3. An index 31 at the device AG is used to transmit destination data to the device 6 and, for this purpose, has teeth which correspond with feelers on the destination device 6, and is pivoted upwards by contact with the carriage 3. In a second embodiment each device AN or AG comprises a manually pivoted member (124, Figs. 3, 4) connected to a locking bar (129) which engages a holding bar (130) on the rail 1 when the member (124) is in its end positions. The locking bar (129) pivotally supports cams (135, 136) operative to lift the bar (129) from engagement with the holding bar (130). In a third embodiment (Figs. 5 and 6), the devices AN, AG comprise a member (226) mounted on a beam (225) which slides in a guide (230).
