Abstract: 787,109. Filters: gravity-separation apparatus. BARNES DRILL CO. Feb. 3, 1956 [Feb. 23, 1955], No. 3481/56. Class 46. [Also in Groups XXIV and XXX] Liquid, e.g. machine-tool coolant, is discharged at 14, Fig. 1, into a receptacle 53 forming the lower end of a shoot 54 up which coarse chips are conveyed by scrapers 65, Figs. 1 and 2, secured to chains 66 which are moved by sprockets 67 fixed to a rotating shaft 28. Liquid with finer solids passes sideways through semicircular openings 63 in the sides of the receptacle 53, each covered by a circular screen 51 secured to the shaft 28, into a pocket formed by two imperforate discs 27, loose on the shaft 28, and by part of an intermittently-travelling sheet of paper or the like 12. Filtrate gravitating through the sheet 12 is collected in a tank 15. The paper 12 is held against the discs 27 and moved, together with the discs, when necessary, by an endless conveyer 20 comprising transverse parallel wire slats 21, Fig. 2, each joined by endloops 22 to an adjacent slat and engaging notches 29, Fig. 1, in two driving sprockets 25. When the level of the pool of liquid 11, Fig. 1, rises above a predetermined point a float 44, Fig. 2, closes a switch 48 by means of a cam 47, whereby, a ring magnet 38, Fig. 6 (fixed to the wall 17 of the tank 15), is energized. The energized magnet grips a ring gear 37 (otherwise loose on the rotating shaft 28) so that the motion of a sun gear 35 secured to the shaft is transmitted to a planet-carrier 39 which is in the form of a sprocket loose on the shaft 28. The sprocket 39 drives, through a chain 40 and other gearing, the conveyer-driving sprockets 25 so that a clean portion of paper 12 is moved along to form the bottom of the pool 11, whereupon the liquid level falls and the magnet 38 is deenergized. The used sheet is collected at 32. Each circular screen 51 is continuously cleaned by a back flow of compressed air supplied at 75 to a tube 74, Fig. 2, communicating with a radial slot 73, Fig. 1, in the side wall of the shoot 54.

Abstract: 1,014,711. Gas liquefaction process. PHILIPS GLOEILAMPENFABRIKEN N.V. Jan. 31, 1964 [Feb. 4, 1963], No. 4222/64. Heading F4P. A permanent gas to be liquefied is supplied periodically from a pressure vessel 1, Fig. 1, through a valved duct 2 to a condensation chamber 4 cooled by a cold gas refrigerator 3 and from which condensed gas is run into a collecting chamber 6 having a valved outlet duct 7 leading to a storage container (not shown) operating at about ambient pressure, the gas supply valve 8 being closed after a predetermined time and condensed gas in chamber 4 being further cooled by the refrigerator 3 until the pressure therein and in chamber 6 falls to that of the storage container after which the outlet valve 9 is opened to effect discharge of chambers 4, 6. Valve 9 is then closed and valve 8 opened at the start of the next condensation cycle. As shown, valve 8 is controlled by a device 10 responsive to the level of liquid in chamber 6 and valve 9 is controlled by a device 11 responsive to gas pressure in chamber 6. In a modification the valves are controlled by a timing device. In a further modification a gas supply duct 32, Fig. 3, leads to a condensation chamber 34 cooled by a refrigerator 33 and from which condensed gas is run through one or other of valved ducts 35, 36 to cooling chambers 37, 38 cooled by refrigerators 45, 46 and having valved outlet ducts 39, 40 leading to a storage container (not shown). In operation valves 41, 42 are initially closed, valve 43 is closed and valve 44 open until such time that pressure in chamber 37 is reduced by the cooling thereof sufficient to allow outlet valve 41 to be opened by pressure responsive control means 48. The resulting drop in level in chamber 37 then causes control means 47 to close valve 43 and open valve 44 thereby allowing cooling of liquefied gas to be continued in chamber 38.

Abstract: 910,181. Shoe bottom presses. BRITISH UNITED SHOE MACHINERY CO. Ltd., and BARKER, W. A. Feb. 10, 1959 [Feb. 11, 1958], No. 4353/58. Class 17 (1). Apparatus for pressing a sole unit, comprising a forepart joined to a heel breast flap by a shank portion, against a shoe having a high heel, has a first resilient fluid-containing pad 8 to press the shank portion and breast flap, and a second resilient fluid-containing pad 10 connected to the first pad by a conduit 28 and supporting a resilient pad 4, 6 for pressing the forepart, so that in operation the forepart pad pressing on the second pad causes fluid to flow to the first pad which becomes distended to conform to the shape of the shoe and presses the shank and the heel breast flap. The pad box 2 coinprising a forepart 2a and cradle part 2b which is hinged at 2c and adjustable heightwise by engaging pin 2e in the desired setting hold 2d, holds a solid hard rubber forepart pad 4 resting on a softer pad 6, and a separate distensible fluid-containing pad 8. The box is movable heightwise on links 18, 20, 22 and the forepart rests on a rubber fluid-containing pad 10. When the shoe is pressed downwardly, by means not shown, fluid passes via conduit 28 from pad 10 to pad 8 which becomes distended and presses the sole at the shank, and the heel breast flap. The part 8e of pad 8 which engages the heel breast is thicker than the part which engages the shank. A leather cover 30 is applied over pads 4 and 8. The heel is supported on a platform 32 carried by links 36, 38 and urged upwardly by a spring, and clamped by a dilatable rubber pad 40 which is mounted in a cradle 42 pivoted on a carriage 46 movable fore and aft. Operation of a treadle, not shown, acts on a bellcrank 50, 54 to move the carriage 46 towards the shoe along slideway 48, and actuates a trailing pawl 64 which engages fixed teeth 66 to prevent movement away from the shoe. As the cradle 42 moves to the dotted line position it rocks and causes pawl 68 to engage teeth 66a and prevent further movement towards the shoe. When pressure is applied to the shoe fluid passes from pad 10 via conduit 70 to pad 40, balancing the pressure exerted by pad 8. Platform 30, which normally projects beyond the heel breast face to engage the lower end of the heel breast flap, is moved to the right, Fig. 1, against spring 72, as pad 8 expands. Specifications 408,953 and 801,545 are referred to.
