Title: Mine roof supports
Inventor: DUNCAN ANGUS WELLESLEY
IPC: E21D15/58
Filed: 1952-05-27
Abstract: 754,107. Hydraulic pit props. MINING ENGINEERING CO., Ltd. May 13, 1953 [May 27, 1952 ; June 23, 1952], Nos. 13462/52 and 15807/52. Class 20(2). [Also in Group XXIX] Energy derived from pressure on yielding mine roof supports due to roof subsidence is stored and used to supply mechanised power to mining implements. In one modification an hydraulic pit prop has a hollow ram 2, Fig. 1, serving also as a reservoir in which is housed an hydraulic accumulator 4 and a rotary valve 7 having passages to connect the prop cylinder 1 through a tube 10 to the accumulator so that when the prop takes the weight of the roof the accumulator is charged. To release the prop the valve 7 is turned to connect the cylinder 1 by a passage 11 to the reservoir and to shut off the accumulator and when the prop is set in a new position it is engaged with the roof by a hand pump 13 and the final supporting pressure is furnished by the accumulator which is connected through the valve 7 to the cylinder 1. The accumulator comprises a piston 6 containing a spring which may be air. In another modification the combined ram and reservoir 22, Fig. 2, is provided with a piston head 23 below which extends a skirt 25 acting as a limiting' stop and containing an auxiliary cylinder 27 having a piston 29 connected by a hollow piston rod 30 to a piston 33 in the ram 22. The accumulator 21 is in the lower end of the cylinder 20. This prop is first set up by compressed air admitted at 35 above the piston 33, which forces liquid from the ram reservoir 22 through the hollow rod 30, the cylinder 27, the control valve 37 to the cylinder space below the head 23 to extend the ram 22 against the roof. The valve 37 is then turned to connect this cylinder space to the accumulator which is thus charged by subsidence of the mine roof. To release the prop the valve 37 is turned to connect again the cylinder space to the reservoir via the auxiliary cylinder 27. The pressure in the accumulator is then used to reset the prop by turning the valve 37 to connect it to the upper side of the piston 29 and to connect the lower side of this piston to the cylinder space. The piston 29 and thus also piston 33 are forced down and the piston 33 forces fluid through the rod 30 cylinder 27 to the cylinder space to set up the prop by acting on the differential areas of the ram provided by the extension 25. The valve 37 is now turned to connect both sides of the piston 29 to the reservoir and to connect the accumulator direct to the cylinder space to apply its force to the full area of the ram 22. In Fig. 3 (not shown) a conveyer is moved by pressure fluid from the accumulator. In Fig. 4 (not shown) these props move each other forward alternatively by crossed links 45 having hydraulic rams 46 operated by pressure fluid from the accumulator of one of the props.

Title: Improvements in free piston gas generators
IPC: F02C5/08
Filed: 1946-05-07
Abstract: 611,767. Free-piston internal-combustion engine gas generators. VICKERS-ARMSTRONGS, Ltd., and DAVIS, D. E. May 7, 1946, No. 13814. [Class 7 (i)] In a free piston internal-combustion engine gas generator of the kind in which compression of air takes place on an outward stroke of a coaxial pair of free pistons reciprocating in a common combustion cylinder and carrying at their ends remote from the combustion cylinder piston-like enlargements reciprocating in end compression and cushion chambers the inner ends of the compression and cushion chambers being utilized as pre-compression spaces in conjunction with the inner ends of the pistonlike enlargements which inner ends draw in and displace a volume of air at each cycle which is greater than the compressor swept volume, the pre-compression space in each compression and cushion chamber is connected to the compression space in the chamber through an airsuction chamber which communicates with the pre-compression space through ports controlled by a part of the free piston assembly, with the compression space through non-return valves and with the atmosphere through suction valves, the arrangement being such that the effective suction stroke in the pre-compression space shortens as the re-expansion of air in the suction chamber increases with working pressure. As shown, suction chambers 9 communicate through ports 10 with pre-compression spaces 8 at the rear of compressor pistons 3. The pistons 3 compress air drawn from the suction chambers through valves 11 during the outward stroke and deliver through a cooler 20 into the engine casing 21. The suction chambers also communicate by ports 18 with cushion cylinders 5. Air enters the chambers through suction valves 12 and ports 13 which may have suction silencers. A pipe 14 interconnects the chambers and from this pipe 14 a pipe 15 with a throttle valve 16 leads to atmosphere. The valve 16 may be operated by the main control of the gas generator or automatically. In a modification, cushion pistons are formed as enlargements of a free piston assembly between compressor pistons and combustion pistons. When the ports 10 are closed towards the end of the inward stroke stabilising cushion spaces are formed at the ends 19 of the spaces 8. By varying the opening of the valve 16 the amount of precompression created by the piston enlargements 3 working in spaces 8 can be varied. An analysis of the pressures and conditions in the gas generator under three stages of working are given in the Specification, the three stages corresponding to three positions of the throttle valve 16 are as follows : (a) valve fully closed ; (b) valve partly open; (c) valve fully open. The initial pressure in the main cushions is approximately equal to the pressure in the stabilising cushions. The suction chambers act as breather spaces and reduce noise. Specification 595,878 is referred to.
