Title: Fixed Increment Advance of Face Conveyors
Inventor: GUPPY GEOFFREY ALBERT
IPC: F15B11/12
Filed: 1966-02-22
Abstract: 1,160,451. Advancing mine face conveyors. COAL INDUSTRY (PATENTS) Ltd. 21 Feb., 1967 [22 Feb., 1966], No. 7729/66. Heading E1P. A double acting hydraulic ram 1, especially for acting with other rams (not shown) to advance a conveyor 2 towards a mine face 2A, has a control circuit associated therewith including means whereby a predetermined volume of liquid may be delivered to the ram to thereby cause a predetermined incremental extension thereof and a predetermined advance of the conveyor. The means for delivering the predetermined volume may be a floating piston 11 slidable along a cylinder 10 when pressurised on one side to force liquid from the other side into the ram, or alternatively, Figs. 5 and 6 (not shown) an accumulator charged from a constant pressure supply or having a fixed volume discharge when charged from a supply above a set minimum. The volume delivered by the piston or accumulator may be adjustable. The circuits of each ram are connected to a pressure line 8 and a return line 9 by way of lines 17, 18 and a control valve 16 normally arranged (as shown) to connect both sides of the piston 11 to the return line 9. To fill the right hand cylinder chamber the valve 16 is shifted to the left, whereafter shifting of the valve to the right causes liquid to flow through lines 15, 13, 13A to open a pilot valve 20 and force the piston 11 to the right so that the contents of the cylinder 10 are dispensed to the ram 1 through the valve 20. A valve 3 operable to extend or contract the ram independently, e.g. for advancing a roof support 1A, is provided. The valve 3 conducts the liquid expelled from the ram during extension back to the pressure line 8. In a modified circuit, Fig. 2 (not shown) the valve 3 normally completely isolates the ram from the pressure and return lines 8, 9 and a further pilot operated valve (31) returns liquid expelled from the ram during incremental extension. Alternative circuits, Figs. 3 and 4 (not shown) for controlling the charging and dispensing of liquid from the cylinder 10 are described. In one such circuit pilot operated valves are provided which are actuated by operation of main valves associated with adjacent or remote ram circuits, the operation of the main valves being effected by the passage of a mineral cutting machine guided along the conveyor.

In a manometer type depth gauge a pipe 16 extends into a liquid, the depth of which is to be measured and is associated with a calibrated indication tube 1 and the pressure exerted by the liquid will cause a small expansion or contraction to be exerted through the piping to a mercury reservoir 3 so as to slightly raise or lower the mercury level in a differential reservoir 2 and this small movement forces a light liquid above the mercury up a small line in the indication tube 1 to execute a proportionally larger movement than that of the mercury in the larger diameter reservoir 2. A suitable light liquid may be composed of 1 part glycerine to three parts water dyed with a fluorescine dye. Should an excessive expansion, due to a choked pipe, produce an overload pressure such pressure is communicated via a pipe 18 to a tube 22 forcing the mercury from tube 22 up a tube 27 so that the mercury and air bubbles, that are forced through the mercury, are driven into a baffle tube 32 where the mercury is trapped by the baffles 42 and returned to the tube 27, the air escaping to atmosphere through two passages 36, 37.

IPC: B24B21/14
Filed: 1953-03-27
Abstract: 726,584. Endless band grinding or polishing machine. McCARTHY, H. A., and STRUCKMAN, E. March 19, 1954 [March 27, 1953], No. 8534/53. Class 60. In a machine for grinding and/or polishing external surfaces, e.g. lengths of metal tubing and the like, having an endless travelling band serving as a carrier for the grinding and/or polishing compound the endless band is supported in contact with the work by a freely deformable surface forming the periphery of a pulley and constituted by a hollow rubber or other flexible tube or tyre the interior of which is at or substantially at atmospheric pressure. A machine for grinding and/or polishing the exterior surface of tubes, rods, &c., e.g. preparatory to electroplating, comprises a worktable 1 mounted on a pedestal base 2 in such manner that it can be raised and lowered relatively to the base, swivelled in a horizontal plane for angular adjustment and moved horizontally in relation to the base. On the upper face of the work-table 1 is mounted a horizontal structure 7 designed to act as a bed along which a trough-like carriage 8 can be reciprocated, the overhanging portions of the structure 7 being supported by struts 11. The carriage 8 is provided with headstock 9 and tailstock 10, and is reciprocated by a drum 12 driven, through reduction gear 14 by a reversible motor 13, the drum being connected with opposite ends of the carriage by flexible belts, wires or chains; reversal may be effected by the user or automatically. The endless burnishing band 17 is supported by an idler pulley 18 and by a non- inflated rubber tyre 15 secured by side plates 16 on a spindle 4. One end of the spindle 4 is supported by an upright 3 extending upwardly from the rear of the pedestal base 2, and the other end is supported by a vertical arm 5 on the outer end of a horizontal sturt 6; the spindle 4 is driven by a motor 25 through belt 26 and stepped pulley 27. The idler pulley 18 is carried by a horizontal bar 19 mounted in a block 21 vertically adjustable, so as to tension the band 17, in a support 20, secured to the pedestal base 2, by a wire 22 one end of which passes over a pulley and is attached to the upper side of the block 21 and the opposite end of which is wound upon a spool within a casing 23 mounted on the strut 6, the spool being rotated by a crank handle 24. When the tyre 15 is stationary, the tensioning of the belt 17 causes partial collapse of the tyre, but when the tyre is revolved at working speed, the tyre is stiffened up by centrifugal force and substantially increases the tension of the band. During the initial stage of the operation the band 17 runs in a plane coincident with the axis of the work A; subsequently, the worktable 1 is swivelled so that the work is diagonally disposed, thus removing scratches. Three bands 17 may be provided for rough grinding or polishing, finer grinding or polishing and finish polishing respectively, the work being moved into position beneath each band in turn by imparting transverse movements to the work-table.
