Filed: 1972-01-27
Abstract: 1408153 Axial-flow fans ROLLS-ROYCE (1971) Ltd 17 Jan 1973 [27 Jan 1972] 3903/72 Heading F1C A mechanism for varying the pitch of a blade of an axial-flow machine rotor is mounted to rotate with the rotor and includes a piston and cylinder which are hydraulically movable relative to one another, the piston or the cylinder being connected to means adapted to actuate a pair of cam plates having oppositely inclined cam surfaces so that movement of the piston or cylinder rotates the cam plates in opposite directions, the rotation being transmitted to means engaging the rotor blade so as to rotate the blade on its longitudinal axis, the piston and cylinder being positioned so that the piston and/or cylinder is movable under centrifugal forces to produce torque in the mechanismopposing the centrifugal twisting moment exerted on the blade during rotation of the rotor. The roots 14 of the variable-pitch fan rotor blades of a gas turbine engine are each splined to a member 15 which is journalled in the rotor disc 16 via a bearing 17 and carries a bevel pinion 18. A hydraulically actuated piston 21 within a radially extending cylinder 20 acts via rollers 32, 33, 34 and cam plates 35, 36, 37 to twin bevel gears 47, 48 in opposite directions, thereby turning the fan blades in unison via the bevel pinions 18. The centrifugal force acting on the piston 21 and tending to move it radially outwards produces a torque on each bevel pinion 18 which balances the inherent centrifugal twisting moment tending to feather the corresponding fan blade.

Title: Device for rewinding clockwork toys
IPC: A63H29/04
Filed: 1931-02-09
Abstract: 362,763. Toys. TRUBERT, R., 2, Rue de l' Arsenal, Arras, Pas-de-Calais, France. Feb. 9, 1931, No. 4011. Convention date, Feb. 13, 1930. [Class 132 (iii).] Railways.-A device for rewinding the spring mechanism of clockwork toys comprises a part of the surface over which the toy is adapted to run, means for holding the toy against motion in the direction in which the mechanism tends to drive it, and means for moving said surface part to cause a movement of the spring mechanism in the opposite direction to that in which the mechanism moves in operating the toy. As shown in Fig. 1, a toy locomotive is maintained by a buffer 7 on a length of track formed by an endless band 3 of rubber or other resilient material. The band is mounted on drums 1, 2 and supported by rollers 4, 5. By rotation of the drums, either manually or by a motor, the wheels of the locomotive are rotated and its clockwork mechanism is rewound. When the mechanism is fully wound, the force exerted by the locomotive against the buffer overcomes a spring detent 10, or a counterweight, rotates the buffer into inoperative position and allows the locomotive to proceed. The rotation of the buffer may serve to break the circuit of the electric motor driving the band. In a modification, Fig. 4, the locomotive is arrested on the band 3 by the engagement of a V-shaped shoe 19, on the locomotive, between a pair of converging contacts 15, 16. The shoe is formed of spring metal and electrically connects the contacts 15, 16 to complete a circuit containing the motor that drives the band. When the mechanism is fully wound, the shoe escapes past the ends of the contacts, and the locomotive proceeds.

Title: Collecting device for producing long wire rod coils
IPC: B65H54/76
Filed: 1975-01-30
Abstract: 1456961 Coiling wire rod MOELLER & NEUMANN GmbH 30 Jan 1975 [23 Feb 1974] 4027/75 Heading D1T Wire rod, supplied in the form of overlapping non-concentric turns 12, are fed by a conveyor 13 to a vertically displaceable centering mandrel 4. Above the centering mandrel 4 are two part-conical members 2a, one on each side of the mandrel 4. The part-conical members 2a jointly define a cone into which four ledges 4a at the upper end of the mandrel 4 can extend. The part-conical members 2a form part of two pivotal arms 2, each generally U-shaped in cross-section and pivotable about axes 17. Figs. 1 and 2 show in full lines the pivotal arms 2 in their upper coil collecting setting; and in broken lines how the pivotal arms 2 can be swung downwardly to a coil release setting 2b'. When the arms 2 are swung downwardly to the broken line setting 2b' the coil 5 does not immediately descend since it remains supported at four points by four interceptor arm means 1 also pivoted about the axes 17, there being an interceptor arm means 1 on each side of each arm 2. When the arms 2 have been swung out of the way of the coil 5, the interceptor arm means 1 swing downwardly to the setting 1' and the coil 5 then drops onto. a collecting plate (not shown) while being guided by the mandrel 4. The mandrel 4 is then lowered to permit the coil to be released for lateral conveyance. During downward movement of the mandrel 4 all of the arms 1, 2 can be rotated back to their starting position, whereupon formation of a next following coil can be initiated.  The downward swing of the pivotal arms 2 is not impeded by the. mandrel 4 because the part-conical members 2a have recesses 2c that permit the members 2a to swing downwardly over those ledges 4a that would otherwise obstruct the movement of the partconical members 2a.

Title: Improvements in or relating to blocks and materials for germinating seeds and growing plants
IPC: A01G9/10
Filed: 1937-02-15
Abstract: A seed-germinating and plant-growing medium in moulded block or loose form comprises sand as its preponderant component and contains an organic binder substantially water insoluble but permitting water to diffuse through the medium.  An albuminous binder may be prepared from scrap leather or leather-board by disintegrating or beating it with water to form an aqueous suspension of leather fibres.  This is then mixed with fine sand and smaller quantities of charcoal and hydrated lime, and water added to form a thick slurry which is heated as it is being formed.  The hot slurry is poured into moulds having foraminous bottoms and allowed to drain and set in a cool or heated atmosphere.  The porous blades may be made in the shape of flower pots, and of animals, bases, lamps &c. on which grass &c. may be grown.  They may also be made in the form of large or small slabs to fit into seed flats or trays.  Corners may be omitted to form recesses or vacant spaces to receive water for the reeds or plants. The charcoal may be omitted and such materials as asbestos, wool, and hair included.  If cellulose fibre is included it is first treated with a fungicidal chemical such as sodium silico-fluoride.  Wool, hair, &c. may be substituted for the leather.  The leather binders may be replaced by glue or the like mixed with formaldehyde, tannin, &c.  Blocks may be formed from a mixture of shredded leather, cellulose fibres or sawdust, asbestos, wool, hair, peat moss &c. with a block-forming composition containing sand and a prepared glue solution.  During drying blocks may be exposed to formaldehyde vapours &c. Fertilizing salts or salt solutions may be sprinkled on the blocks or added to the water in which the blocks are partially submerged.  The side walls may be wrapped with waterproof material. Seeds may be placed on the top of the blocks or in holes in them and covered with sand or with the material removed from the holes.  They may be germinated in a warm dark room and then exposed to sunlight and treated with fertilizer, the blocks and plants being afterwards inserted in the ground or in flower pots.  The blocks may be used for testing germination of seeds. Slips or cuttings may be started in holes in the blocks.  For use in a loose or granular form the ingredients may be mixed in a dry state, or may be mixed in water and then heated, dried, and disintegrated.  Lime or other alkali may be included to neutralize tannic acid, regulate the pH value, saponify grease, minimize the generation of glutinous substance &c. Fertilizers added may comprise bone meal, superphosphate, fish meal &c.

Title: Improvements in brakes, clutches and the like
Inventor: BUTLER HENRY JAMES
IPC: F16D65/18
Filed: 1958-02-13
Abstract: 915,741. Friction clutches. DUNLOP RUBBER CO. Ltd. Jan. 26, 1959 [Feb. 13, 1958], No. 4693/58. Class 80 (2). [Also in Group XXXIV] In a brake or clutch an automatic adjusting device is provided which comprises a pin 11 secured to one of two relatively displaceable portions of a fluid-pressure mechanism associated with the brake or clutch, for example a fluid-tight closure member 7 secured to a non- rotatable torque member 2 of the disc brake illustrated, the pin 11 extending within the movable portion (piston 5) of the fluid-pressure mechanism, resilient means 14 urging the movable portion away from a rotatable member of the brake or clutch against a fixed stop 13 in the movable portion and an interference member or second stop in the form of a helical spring 16 frictionally engaging the pin and adapted to move relative thereto when the displacement exceeds a limited distance. In operation, a sleeve 15 is slidably housed in recess 5c in the piston 5 and is pressed firmly against interference member 16 by a spring 14 such that the piston 5 is free to move for a limited distance by sliding on sleeve 15 such that when the sleeve abuts the plate washer 13 and the clearance between the end of the sleeve and the plate washer together with the clearance between the friction-pad 6 and the disc 1 are both eliminated, the brake is fully applied. As the friction pad wears, the sleeve 15 abuts plate washer 13 and causes the flange of the sleeve to press against the interference member 16 and move the latter down the pin until the brake is fully applied. When the brake is released, the pressure of the spring 14 against the plate washer retracts the piston and friction pad from the disc until the sleeve comes into abutment with the step against which it is normally seated, and the friction pad is thus retracted through the axial distance of the annular space between the open end of the sleeve and the plate washer.
