Abstract: 1,093,361. Shaft couplings. MIRRLEES NATIONAL Ltd. Aug. 21, 1964 [May 31, 1963], No. 21790/63. Heading F2U. In a vibration damping shaft coupling for diesel marine drives, comprising coaxial input and output members 14, 23 which define an annular space filled with hydraulic fluid, across which extend alternate radial vanes 20, 24 mounted on the input and output members 14, 23 respectively, restricted fluid flow between the alternate high and low pressure inter-vane spaces provides torsional damping, pressure release means permit relative angular displacement between the input and output members under load and prevent transmission of torsional oscillations, and when the relative angular displacement exceeds a predetermined value, high pressure hydraulic fluid is admitted through bores 11b, 11c and recesses 14a to apply a restoring torque to the vanes. One of a pair of annular galleries at the ends of the coupling (not shown) is connected through holes 15f to alternate inter-vane spaces, the other gallery being connected through holes 13f to the remaining spaces. Above a predetermined angular displacement, a recess 14b and a bore 14c connect the low pressure spaces to a low pressure relief valve (not shown). Diametrically opposite the recess 14b, a pair of angularly and axially spaced bores 14g with separate non-return valves co-operate with bores 14j and recesses 14h in the adjacent vane 24 to connect the high-pressure spaces to a high pressure relief valve which remains closed up to a predetermined steady pressure but opens when subjected to a fluctuating pressure of lower value. The ends of vanes 24 carry lateral sealing strips 24a. Restricted flow between the high and low pressure spaces is past the vane tips and may also be through restricted passages in the input and/or output members.

Agglomerating p r o - cesses. - Improvements are effected in the apparatus for roasting ores described in Specifications 1 7 3 4 3 / 0 7 , 17344/07, and 25985/07. Fig. 2 shows a side elevation of the improved mechanism. The gratebottom ore carriers or pallets 6 are driven along the rails 9 by means of the sprocket-wheels 19 and return along rails 10 propelled by the sprocketwheels 20 set in motion by the upper row of pallets. The sprockets 20 are mounted on a shaft 32 resiliently held by springs 36. The emptied pallets are filled under the hopper 41 and the ore is ignited by the projection of solid flaming carbonaceous powder from the igniter 39<a>, Fig. 19. This comprises an open-bottomed box 60 suspended over the frame and a duct 62 supplying finely powdered carbonaceous material in an air current, the volume and pressure of the stream being controlled at the nozzle 63 by devices 67 and dampers 66. Air is drawn through the pallets, air-boxes 40, and pipes 44 by means of the fan 42. The sintered ore is discharged on the shoot 37a. The gears are secured to the outer sides of the sprockets 19, and the gearing parts are made readily accessible and replaceable. The weight of the loaded pallets is borne by the wheels 8 on the rails 9, an air-tight joint with the air-boxes 40 being secured by means of laterally adjustable packing-strips 45, Fig. 12. The strips may be secured in rabbets so as to bear against the flange 14. Engaging with the teeth of the sprockets 19, 20 are rollers 17 which permit the wheels 8 to roll on the curved guides 37, 38 whilst the pallets are being directly propelled. Each pallet frame has side walls 11, Fig. 12, and skirt walls which successively seal the ends of the air-boxes. Grate-sections 7 rest on ledges on the pallet frame and may be secured by pins 25<a> inserted in the walls 11. The spaces between the grating bars are longitudinal to allow of cleaning by means of bars 53, Fig. 15, with hooks 56 loosely engaging a cross-bar 54 and fingers 55 dipping into the grooves. Accidental backward movement of the pallets disengages the hooks from the cross-bar.

Title: Improvements in and relating to hop-picking machines
IPC: A01D46/02
Filed: 1937-08-13
Abstract: 486,830. Harvesting hops. THYS, E. Aug. 13, 1937, No. 22307. [Class 6 (iii)] Cut hop bines are placed by attendants, standing on a platform 23, between clamping jaws, one jaw being held open by an overshot toggle action until the lower end of a bine has been inserted when the toggle is tripped by hand. One pair of jaws is carried at each end of cross-bars extending between endless chains G, G, passing over sprockets 2 .... 9. A distance approximating to the length of a bine is arranged between successive cross-bars. The bines as they are drawn upward by the chains are treated by flexible wire fingers extending from bars carried by endless chains travelling round sprockets mounted on pivoted frames 26 .... 29, these frames normally being held up by springs 48 close to the upper run of the chains G, G, but at intervals being swung downwards and held in slightly depressed position by members 50 co-operating with latches 51. The detached hops fall on to filler bars extending between the chains of the frames 26 ... 29 and are carried round until they fall from the lower side of these frames on to a combing device consisting of fingers 58 carried by cross bars extending between a pair of endless chains 56 positioned below the lower run of the chains G, G. This combing device detaches the hops on the other side of the bines and carries them in troughs formed by filling plates between the cross-bars to discharge them on a grid 75 through which the separated hops fall on to the upward run of a conveyer 77. Clusters of hops are broken by the action of the fingers. The bines are dragged to the lower end of the downward run of the chains G, G and pass between rubber covered rollers 62, 63, these rollers being moved apart by cam action to permit the passage of the jaws with the lower portion of the bines and then closed again on the stems : the jaws are opened in the run between the sprockets 9 and 2 by a cam 70, releasing the bines which are discharged by the rollers 62, 63. The hops fall from the conveyer 77 on to closely spaced wire fingers 80 over which they slide with some of the leaves to a separating belt 81, stems and some leaves falling between the fingers to a conveyer 82. The leaves with the hops are held against the belt 81, which is closely meshed, by suction from a fan 86 while the hops fall into a bucket conveyer 87 which passes under a brush 89 to remove the last fragments of stems, the cleaned hops being discharged through a shoot 91 and cross belt 92 to an upward air blast that carries them to a sacking shoot, any heavy impurities falling down against the blast. Specification 3248 /13, [Class 6 (iii)], is referred to.

Title: Improvements relating to variable-speed gears
IPC: B23Q5/34
Filed: 1957-07-15
Abstract: 829,833. Variable-speed gearing. MACHINE TOOL WORKS F. STUDER Ltd. July 15, 1957 [July 14, 1956], No. 22387/57. Class 80 (2). Gearing giving either a solid direct drive or a reduced speed in the opposite direction, particularly suitable for the drive of a machine-tool part by a hand wheel 7, comprises a fixed reaction sun-gear 3a, a driven sun-gear 4 on a driven shaft 2 and a pair of planet pinions 11, 13 on a shaft 10 rotatably carried on the hub of the hand wheel which mesh respectively with the sun-gears 3a, 4. The shaft 10 is secured to the planet pinion 11 and has a conical extension 12 at that end adapted to engage in a conical recess of the pinion 13 and at the other end a screwthread on which is mounted an adjusting- member 16. The member 16 also engages a rod 14 passing through shaft 10 with a head 14a at its other end engaging the pinion 13. When the member 16 is screwed in one direction the shaft is moved to the left to disengage from the pinion 13 and lock on to the hub of the hand wheel 7. The pinion 11 is thus locked and the gear will drive the sun-gear 4 and shaft 2 solid. If the member 16 is rotated in the opposite direction the shaft 10 is moved to the right to free from the hub of hand wheel 7 and lock on to the pinion 13 through the cone 12. An epicyclic reduction is then obtained from the hand wheel 7 to the shaft 2.

Abstract: 637,710. Fluid-pressure servomotor-control systems. DOLE VALVE CO. July 27, 1944, No. 22388/48. Convention date, March 1, 1944. Divided out of 637,643. [Class 135] A mixing valve comprises a housing with hot and cold inlets 11, 12 respectively, and a valve with closure members 30, 31 differentially controlling the passage of the hot and cold supplies to a mixing chamber from which the mixed fluid passes to the outlet 19 past a thermally-responsive element 54. The position taken up by valves 30, 31 is determined by a diaphragm 36 subject to the pressures in the mixing chamber and in an auxiliary chamber 44 which latter is supplied with fluid from the inlet 11 through a passage 47 and from which fluid can leak to the outlet through a passage 50. The leak from passage 50 is controlled by a valve 53 connected to the thermal element 54 so that the pressure in chamber 44 and, hence, the relative amounts of hot and cold fluid allowed by valves 30, 31 to flow to the mixing chamber is dependent on the temperature of the mixed fluid. In a modification, the spring which loads valves 30, 31 is replaced by a further auxiliary chamber, similar to chamber 44, but fed from the cold inlet. The valves 30, 31 are also constituted by two interconnected diaphragms similar to diaphragm 36.
