Abstract: 738,987. Elastic fluid turbines. WILLIAMSON, D. D. Dec. 4, 1953 [Dec. 5, 1951], No. 30868/52. Class 110 (3). In an elastic-fluid turbine, for example a gas turbine, of the inward radial-flow type, a guide vane assembly is mounted on the stator, the assembly having at least two sets of guide vanes, the vanes of one set having a different angle of inclination to the radial direction from the vanes of the other set, the assembly being movable so as to bring one or more of the sets of guide vanes into the path of the gas entering the rotor. The set or sets of guide vanes operative at any time is or are the only guide vanes controlling the direction of gas entering the rotor. The gas turbine shown has a rotor 11 with vanes 14 and is mounted in a stator 10. The guide vane assembly 20 is annular and comprises three sets of vanes 25, 26, 27, the assembly being movable axially by means of the rod 22 so that one or more of the sets of vanes is or are in line with the rotor vanes. The vanes 25, 27 are inclined on opposite sides of the radial direction and the vanes 26 are radially directed, the rotor being rotatable in either direction when the vanes 25, 27 are operative, and when the vanes 26 are operative, no torque is applied to the rotor by the gas passing therethrough. The set of radial vanes 26 may be dispensed with, the " stop " condition being obtained with the vanes 26, 27 extending equally into the gas flow path. Specifications 618,193, 691,144 and 696,817 are referred to.

Abstract: 907,920. Conveying articles through tanks. UDYLITE RESEARCH CORPORATION. Sept. 8, 1960 [Nov. 23, 1959], No. 31025/60. Class 78 (1). Racks 24 containing workpieces to be treated in tanks 22 are passed step-by-step along the tanks by a reciprocating cammed pusher. Pusher bar 84, Figs. 2 and 4.-A basket 24 is carried at the end of arm 60 pivoted at 70 to carriage 58 running on rail 42 parallel to the length of the tanks. Arm 60 carries cam follower 120, the roller thereof resting on cam 128 secured to pusher bar 84. Pusher bar 84 is caused to reciprocate by a fluid cylinder along guide 86, the pusher bar making engagement with arm 60 in two ways; pusher 88 on bar 84 engages lug 80 on carriage 58 to give the carriage a translational movement forward, the pusher 88 pivoting on the return movement to leave the carriage one step forward, and cam 128 on pusher 84 engaging follower 124 to raise the arm 60 as the latter progresses in its step forward. Thus, as the arm 60 goes forward it is raised, so that basket 24 can clear a partition between two tanks and then drop down into the next tank. Fluid drive, Fig. 6.-Fluid cylinder 104 operates pusher bar 84, being connected thereto by bar 114, and additionally operates pusher arms 94 secured to shaft 96, being connected thereto by arm 112, so that pusher bar 84 progresses the carriages step-by-step along the straight path and then the carriages are pushed around the bends by an arm 94. Modified cam 128, Fig. 9.-Cam 128 is furnished with a secondary cam 144 coupled thereto by pin-and-slot arrangement 150, 154. The two cams move together on the forward movement of pusher bar 84 and, on the return journey of the pusher bar, plunger 168 is operated to retain cam 144 in its advanced position (as shown), cam 128 returning with the retracting pusher bar whilst leaving carriage 58 with its follower 120 on top of cam 144. In this way, the pusher bar reciprocates whilst leaving the arm 60 of a carriage 58 in the raised position, the respective rack 24 remaining in the abovetank position.

Nov. 13, 1936, No. 31081. [Classes 78 (i) and 78 (iii)] Apparatus for stacking articles of the type described in Specification 450,251, comprising a series of racks each having a number of article supports disposed one above the other and being movable vertically to bring any of the supports to a loading level, and means for conveying the article to a rack-loading position, is characterized by the provision of means for feeding articles into two or more racks simultaneously. In one embodiment in which pallets carrying freshly-made tiles are delivered to two drying racks, a series of racks 50, Fig. 1, are arranged adjacent an endless conveyer 55 along which the pallets are fed from a tilemaking machine, the racks being suspended in pairs by ropes 54 so as to counterbalance one another. The pallets are positioned on the conveyer in pairs opposite the rack supports by a device as shown in Fig. 4, and are fed into the racks by means shown in Fig. 2 carried on a truck 58 which runs on rails in front of the conveyer. As the first of a pair of pallets is moved along by the conveyer, it engages and tilts a member 110, Fig. 4, about its pivot 111 on the truck and is held stationary on rollers 70 by a stop 112. The tilting of the member 110 brings a stop 113 and trigger 114 into the path of the succeeding pallet. This pallet depresses the trigger and is then held by the stop. With the two pallets thus positioned, they are fed into the racks by fingers 11, Fig. 2, pivotally mounted on a cross-head 10. This cross-head is carried by a rack 33 which is slidably mounted on the truck and engaged by a pinion 32 rotated through a chain 116, lever 28 and roller 27, by a cam 26 on a shaft 24 which is driven through a clutch by a motor 23 when the trigger 114 is depressed as described above. After a predetermined number of feeding operations corresponding to the complete loading of one shelf, the weighted arm 45 of a lever 43 falls under the control of a cam 132 driven from the shaft 24, whereby a lever 47 is rotated about its pivot 132, Fig. 5, on a bracket 131 adjacent the racks, to depress a rod 134 slidably mounted on the bracket and, through arms 137, 138, move the racks to bring the next shelf in line with the feeding device. These arms 137, 138 are pivotally mounted on the rod 134 and engage teeth 337, 338 respectively, on the racks when they are suitably positioned by projections 237, 238 on an adjustable plate 140. The means for feeding the pallets from the conveyer may comprise a hydraulic ram.

IPC: G05G7/04
Filed: 1967-07-08
Abstract: 1,174,855. Brake linkages; linkwork. VAUXHALL MOTORS Ltd. 20 June, 1968 [8 July, 1967], No. 31539/67. Headings F2E and F2K. A variable ratio lever mechanism having an increasing mechanical advantage during a stroke is mounted on a stationary part of a motor vehicle axle and is connected by an output linkage to the brakes of the wheels carried by the axle. The lever mechanism comprises a bellcrank lever 30, Fig. 2, connected by one of its arms 28 via cable 22 to a hand brake lever (not shown), and pivotally connected at the end of the other arm 32 to an arm 34 of a second bell-crank lever 36 mounted on a fixed pivot 38 whose other arm 40 is connected via compensation lever 64 to output cables 24, 26 connected to the wheel brakes. The lever 30 is also pivotally mounted on one arm of a control bell-crank lever 42, itself pivotally mounted at 44 on a ratchet lever 46 mounted on fixed pivot 38, the lever 42 being biased by spring 48 to a position in which it contacts stop 62 on lever 46. The free end of the lever 46 is provided with a pivotally mounted pawl 50 biased by spring 54 into engagement with a ratchet 52, but which may be held out of engagement with the ratchet by a cam surface 60 on the bell-crank lever 28. In operation, with initial pull on the hand brake and cable 22 the lever mechanism pivots as a whole about fixed pivot 38 to provide an initial quick take up of slack, Figs. 3, 4 (not shown), the pawl being held by cam surface 60 out of engagement with the ratchet. Subsequently the spring 48 begins to yield so that the mechanism changes to a condition in which the pawl is engaged with the ratchet, Fig. 5 (not shown), so that with increased pull on the hand brake, pivotal movement of the lever 30 takes place about an instantaneous centre which moves progressively away from fixed pivot 38 towards the connection between the levers 30, 36, Figs. 6, 7 (not shown), thereby producing an increasing mechanical advantage during the final movement of the lever 30. The lever mechanism is mounted on the rear axle 12, Fig. 1, of a vehicle resiliently supported, by leaf springs 14, on the frame 16. The axle contains a differential gear mechanism for supplying a drive from a propeller shaft 18 to driven rear wheels 20 of the vehicle.

Title: Improvements relating to penstocks, sluice gates, sluice valves and the like
IPC: E02B9/02
Filed: 1936-11-19
Abstract: 485,122. Sluice-gates. DEANE, H. J. Nov. 19, 1936, No. 31726. [Class 68 (ii)] Sluice-gates, penstocks, &c. are opened and closed automatically through differential or epicyclic mechanism in dependence upon relative and actual water levels upon the two sides of the gate &c, Pulleys A, A<1> or conical shafts are connected to floats on opposite sides of the sluice-gate in such a way that movement of the floats in the same direction causes movement of the pulleys in opposite directions. The pulleys each drive bevel wheels B, B<1> of epicyclic gear including planet pinions C, C<1> on the carrier arm L. Movement of the arm L is thus dependent only upon the relative levels of the water and not upon their absolute levels. When the relative levels differ sufficiently, the consequent movement of arm L causes contactor D to close circuits through spaced switch members to open or close circuits through electromotors adapted.to open or close the gate. A contactor D<1> connected to one of the bevel wheels and thus dependent upon absolute level of one float, may also close a circuit through one of the motors. Contactors D, D<1> are both adjustable. The closing of the contactors may operate indicators showing the necessity for operation which may then be effected manually. The arms F and F<1> co-operating with contactors D, D<1> may be adjustable.

Abstract: 533,875. Stretching. ALUMINUM CO. OF AMERICA. Dec. 7, 1939, No. 31733. Convention date, Dec. 14, 1938. [Class 83 (iv)] In a machine for stretching sheets, plates or strips, the sheets &c. are gripped by devices each consisting of opposed jaws one or both of which incorporate a number of interconnected self-adjustable sections so that uniform distribution of the tensile forces may be imparted to the sheet despite irregularities in the thickness thereof. The sheet is placed between the jaws of a pair of stretching heads movable on a track 2, one of the heads being adjustable by motordriven screws and the other 3 being operated by hydraulic or like rams to stretch the sheet. Each head has a number of upper and lower jaw sections 8 which are slidable on the outwardly converging inclined plane surfaces of the'recess in the head, the jaws are provided with serrated inserts 27. The lower sections rest by gravity on the lower inclined surface and the upper sections have T-slots 28a and are held in relatively free sliding engagement with the upper inclined surface by T-shaped keeper bars 28 disposed centrally of the jaw sections and shaped to allow small angular displacement of the sections. The sections are each moved into clamping position by separate push rods 25 and levers 21, which are actuated through separate springs 17 by a flanged beam 16 which is connected at each end to links 15 operated through bell crank levers 13 by air cylinders 10. The springs are adjustable by screws 19 through seats 18. When the cylinders 10 are operated the sections angularly adjust themselves in the planes of the inclined surfaces of the recess in the head to engage work of irregular dimensions. The ends of the sections are connected by swivel pins 30 to prevent adjacent edges of the sections from being displaced independently of each other. Similar pins are provided between the outside sections and retaining plates 29. The pins may be retained in their bearings by dowel pins.
