Abstract: 649,723. Walking toys. SHAKESHAFT, J. E. Oct. 28, 1947, No. 28705. [Class 132 (iii)] A walking toy comprises a body part 1, advanced by external means, to which are pivoted leg parts which, as the body is advanced, alternately engage a surface and are caused to swing rearwardly while the other leg part swings forwards and is characterized in that the leg parts comprise two pieces 3, 5 pivoted together, the provision for each leg part of an over-centre spring linkage connecting the two pieces together and arranged to hold the two pieces in an extended and in a partly folded position and abutments on the body-piece which operate to make and break the linkage at the opposite extremities of swinging movement of the leg parts. The upper parts 3 of the leg parts are pivoted on the body part 1 and engage cranks 24 which operate arms 22 oppositely to their adjacent leg parts as shown. The leg parts 5 are pivoted to the parts 3 and also connected to the part 3 by a spring 12 and an over-centre linkage 8, 10. The leg parts are interconnected by a pivoted bar 18, whose ends 20 engage the parts 3, so that as one leg part swings forward the other swings back. As one of the leg parts swings back in contact with the ground it is held straight until the link 10 strikes the abutment 13 when it bends and is then swung forward until the links strike the lever 14 and the leg part straightens. The figures may be supported by a wheeled truck which it appears to pull along.

Abstract: 287,262. Lessing, R. Jan. 11, 1927. Pneumatic separating.-In the separation of powdered granular material, such as coal, pigments &c. the material is fed into a tubular vessel up which is moving a current of gas which removes the finer ingredients and passes upwards into a tubular extension having one or more ports for the removal of middlings the dust being carried off by the gas current and deposited in a suitable collector. In a two-stage apparatus by which the middlings from the first stage are subjected to a separating operation, the material is fed from a hopper 10 by a conveyer 11, shoot 12 and control flaps 13, 14 to the vertical tube 1 which is of uniform circular section over the length AB and tapers downwards to C near the shoot 16 by which the coarse particles are discharged to a sealed bin 17. In the upper part, the tube merges at D into a rectangular sectioned portion extending to E and having a middlings discharge opening 20 in an enlarged part F. Above E the tube narrows towards the dust collector 3 of the cyclone type. The gas returns by way of the pipe 4, fan 5 and tubes 6 and 7, with control valves 18, 19. At the bottom of the tube is placed a grid 15 on to which the coarse material falls, being subjected to a current of gas from the bye-pass 6. The middlings from the openings 20 are treated in similar apparatus, the separating tube being modified by the insertion of a constricting member 28, and the middlings being discharged by a launder 30 and pipe 31. In each stage a number of middlings discharge openings may be provided. Pipes 8, controlled by valves 22, leading from the main gas stream may carry an aspirating current into the middlings discharge tubes. Flow actuated devices 27 of ordinary construction may be provided to regulate the gas current. Inspection doors 36 - - 39 may be fitted at suitable points.

Abstract: 715,773.. Vibratory mechanism. BARKER & SON ENGINEERS, Ltd., W. H. Dec. 3, 1952 [Dec. 11, 1951], No. 28998/51. Class 80 (4) In order that a spring-supported screen which is vibrated by a motor-driven out-ofbalance pulley is not vibrated at its resonant frequency while the. motor is increasing or decreasing speed, the pulley is arranged, to become unbalanced only at speeds greater than the resonant speed. A mass c fixed to the pulley is balanced at low speeds by a mass d loose on the pulley shaft, the mass d being held in its balancing position during rotation by a spring f against a stop e on the pulley. The masses c, d are interconnected by links g whose pivot carries a weight h so that at speeds above resonance the centrifugal force on the mass h overcomes the spring f and moves the mass d out of its balancing position to rest against a further stop so that the pulley is then unbalanced and vibrates the screen. The screen is suspended by spring- supported rods and has therethrough a shaft carrying two vibration pulleys, one of which is belt-driven from a stationary electric motor.
