Title: Filling apparatus
IPC: F17C5/00
Filed: 1961-01-30
Abstract: 913,948. Delivering measured quantities of liquid. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Jan. 30, 1961 [Feb. 1, 1960], No. 3435/61. Class 106 (5). A free-piston type dispenser 30, 31, particularly for filling steel bottles with liquefied gas such as butane, has stops 38 or 59 at one or both ends of the cylinder 31 to control pneumatic valves for reversing the supply and delivery lines to the cylinder. After the bottle to be filled is connected to a line 10, pneumatically-operated drain valves 8 and 7 are opened in succession by valves 3 and 4 to drain liquid and then gas or air from the bottle. When a starting valve 2 is pressed, compressed-air from a line 1 moves a valve 16 into the position indicated by dotted lines and air flows to a fill valve 9 and through a valve 22 to valves 24 and 25 which connect the delivery end of the cylinder 31 to the fill valve and supply the liquid under pressure from a supply line 28 so that the piston 30 forces the liquid above it into the bottle. When the piston reaches the top of the cylinder, it moves the stop 39 to change-over a valve 39 and air is supplied to a plunger 44 to operate a counter 46, to the valve 22 to change it over and, through a ball valve 49, to the valve 16 to move it back to its original position. The bottle just filled is replaced or the line 10 is switched to another bottle and a similar cycle is re-started by actuating the valves 3, 4 and 2, but the delivery to the fill valve is from the lower end of the cylinder. When the piston strikes the lower stop 59, the valves are returned to their original positions and another counter 66 is operated by a plunger 64. The valves 2, 3, 4 may be operated automatically by a cam-shaft with three cams. The stops comprise a rod 86 which operates the slide 90 of the pneumatic valve 93 and the rod and valve are mounted in a member 77 mounted for axial movement in the cylinder cover 70. The member 77 is adjustable by a wheel 76 in screw-threaded engagement with a bush 72 and having a flange 80 engaged with the member 77. A spring-loaded ball 82 engages in bores 81 arranged in a helical line on an extension of the wheel. The wheel may be adjusted by hand or by temperaturemeasuring means that compensate for temperature fluctuations. The adjustability of the stops may be omitted if means are provided for keeping the temperature of the liquid constant. The piston 30 is provided with packing and with a scraper ring.

Abstract: 395,976. Testing abrasive qualities of materials and testing lubricants. TIMKEN ROLLER BEARING CO., Denber Avenue, Canton, Ohio, U.S.A. Feb. 9, 1933, No. 3958. Convention date, March 13, 1932. [Class 106 (ii).] A testing-machine has a rotatable test ring 28 'and a pair of levers 30, 33 pivoted one upon the other, the upper lever 30 carrying a test block 41 adapted to make line contact with the test ring 28. The latter, Fig. 2, is clamped by a nut 29 to the tapered portion 27 of an arbor 4 which is driven by pulley 5 and belt 6 and which is supported in roller bearings 13. The upper lever 30 is suitably weighted at 43, Fig. 1, and is fulcrummed on knife edge 31 of lever 33 ; and the fulcrum 35 of the lower lever being exactly beneath knife edge 31. Block 34 has a transverse knife edge 36 resting on block 38 to give universal action. A pointer 44 on lever 33 reads against a scale 45 and lever 33 is so balanced that normally it lies horizontally. As ring 28 rotates, it tends to move test block 28 laterallv and exerts a force on knife edge 31 so that lever 33 is rocked. The weight at end 43 of lever 30 being known, by placing weights at end 43 of lever 33 sufficient to bring it back to the horizontal, the frictional moment is known. Screen 46 normally holds lever 33 horizontal, but is adjusted the necessary amount during a test. Oil is supplied from a pipe 62. To test the qualities of different lubricants, the same test block 41 and the same weight at the end 43 of lever 30 are used and the different lubricants are supplied from pipe 62. In a modification the test block 41, instead of being attached firmly to lever 30 as by wedge 42, Fig. 1, is fastened to a carrier which is pivoted by a knife edge on to the lever 30. A test bearing 47 for ascertaining the abrasive (wearing down) property of the lubricant comprises two cones 48 mounted on a shaft 50 and spaced by a ring 49. Between these cones and cups 53, spaced by ring 54, are roller bearings 55 in cage 56. Engaging over extensions of shaft 50 are slots 57 of two levers 58, pivoted at 59 and weighted at 61. The normal weights of the parts keep the cups 53 in engagement with the test ring 28 driven by shaft 4 as above described. Oil is supplied to bearing 47 by pipe 63. The amount of wear in bearing 47 is ascertained by weighing and measuring the bearing after it has run for a specified time.
