Abstract: 951,051. Step-by-step lifting jacks. D.D.R. RANKIN, and K. E. ANDERSON. Jan. 6, 1960, No. 39953/59. Heading B8J. [Also in Divisions E1 and F2] In a step-by-step lifting jack in which lifting is effected by relative movement of a screw 12 and the jack casing 4, the screw is lifted by a wedge 27 acting on a nut 22 through a vertically movable abutment member 19. As the screw is raised, a nut 21 is rotated so as to remain adjacent a fixed abutment 18. As the wedge is withdrawn, the position of the screw is maintained by the nut 21 engaging the abutment 18, while the nut 22 is rotated so as to follow the abutment member 19. The wedge is driven by a piston 34 which also drives the nuts 21, 22 through link 68, slide block 66 driving chain 60 through a yielding tooth 67 (not shown), sprocket 59, oscillatory shaft 49, sprockets 48, 51 and chains 45, 50. Coupling of the sprockets 48, 51 to the shaft 49 is effected by pawls 56, 58. Reversing pawls 71, 72 (not shown) are associated with the pawls 56, 58 and may be adjusted to allow a single reverse step to be effected before the pawls are returned to their normal position by trip levers 90, 92. In some of these operations there is lost motion.

Abstract: 1,268,972. Refining sugar. BIRD MACHINE CO. Aug. 18, 1969[Aug.20, 1968], No.41208/69. Heading C6B. A method of treating a magma of sugar crystals to remove surface impurities from the crystals, drain the syrup from the mass of crystals, and wash the syrup from the crystal faces, comprises feeding the magma continuously to a rotary impervious centrifuge bowl 20 to form a pool in which all or most of the sugar crystals separate from the liquid under centrifugal force to form a bed held against the inner surface of the bowl by centrifugal force, draining liquid from the pool continuously, e.g. via openings 42, to maintain the pool volume substantially constant, scrubbing the crystals in the bed by pushing and tumbling them along the surface of the bowl towards a sloping surface 22, along which the crystals are moved to separate them from the liquid which drains back into the pool, and continuing the pushing and tumbling movement of the crystals along a cylindrical screen drum 24, which adjoins the smaller radius end of the surface 22, while draining further liquid from the bed through the screen drum. During passage of the bed through the screen drum water or steam is preferably sprayed on to the bed from nozzle outlets formed in a rotatable core 30, the water or steam being supplied by a pipe 34. The pushing and tumbling of the crystals along the various surfaces 20, 22, 24 is effected by a conveyer having helical flights, preferably in the form of a double helit 28 provided on the core 30, the drum formed by surfaces 20-24 and the core 30 being rotated at different speeds to provide the desired conveying action. Supply of magma to the pool is effected by a pipe 14 surrounding the pipe 34, via apertures in the pipe 14 and apertures 32 in the core 30. The liquid drawn from the pool via openings 42 passes into one compartment of an outer casing from which it drains at outlet 40, further compartments being provided in the casing to receive different fractions of the liquid washed from the crystals in the screen drum and leading to outlets 56, 54, respectively. The refined crystals are discharged at outlet 38. Additional water or steam spray may be supplied by a manifold 60 for cleaning the screen drum.

Abstract: 850.782. Pit-props. BARKER, R. E. May 12, 1959 [Dec. 23, 1958], No. 41513/58. Class 20(2) A telescopic pit-prop has one of more collars 1 frictionally gripping the inner prop-member p to sustain the load. A wedge 7 and a block 9 act together to pull the portion 6 of one end of the collar through a slot 4 in the other end, to tighten it. A corner-piece 10, located by a lug 11 engaging the aperture 5 provides clamping substantially around the whole circumference of the prop-member. A lining 12, preferably of a copper-lead alloy increases the frictional grip. In another form of collar, (Fig. 4 not shown) an eccentric cam provides the wedging action. One of each type of collar is normally provided, the Fig. 1 type providing the initial tightening of the prop and the cam type a finer adjustment of yield pressure.

[Class 83 (iv)] [See also Group II] In machines for reducing or compacting the volume of hollow bodies e.g. metal containers, tin boxes, canisters, &c. of the type in which one or more rotary elements cooperate with a stationary, yielding, and /or adjustable serrated member or members, the rotary elements are formed of toothed discs 6 loosely mounted on a driving- shaft 1, relative rotary movement of the discs being prevented by projections on the sides of each disc, or of certain discs, engaging recesses in an adjacent disc or discs, while the discs are driven by being secured through tie-rods 7 to end discs 8 fixed to the shaft 1. The projections, e.g. of rectangular or arcuate section, may be formed integral with the discs or may be plugs projecting from one or both sides of the discs. The serrated members 11 are secured to an arm 13, Fig. 2, pivoted at 14 and secured at its lower end between a spring-pressed rod and an adjustable screw-threaded rod. To facilitate removal and insertion of the discs 6 without removing the shaft 1 from its bearings 2, the discs are formed in equal or unequal sections connected e.g. by dovetailing, the end lining-plates of the machine framework being also formed in sections 15, 15<a> for the same purpose. The preferred arrangement of the working parts relatively to one another is described in detail.

The auger 21 is axially movable relative to the auger 12 to open or close the lower end of shaft 20, and is fed from a hopper 28. When forming piles, relatively thin, soil-penetrating grout may be pumped through the shaft of auger 21 to form an enlarged foot for the pile and to strengthen the soil around the periphery of the pile. The cutter 22, rotated by auger 21 compacts the material introduced. In a modification, the cutter 22 has a hydraulically controlled radially extendible blade so that the cavity formed may be given an enlarged base.
