Title: Improvements in or relating to fluid pressure intersifiers
Inventor: MARTON-FALVY IVAN CHARLES DE
IPC: F15B11/032
Filed: 1963-03-18
Abstract: 958,018. Fluid pressure intensifiers. E. MATHEWS ENGINEERING CO. Ltd. March 18,1963, No. 10612/63. Heading F1P. A fluid pressure intensifier comprises a stepped intensifier piston 38 slidable in a cylinder 14 and also on a fixed tubular stem 28 which passes through the cylinder and is secured to the end flange 13 of a ram cylinder 10 having a ram 23 slidable therein, and an axial bore 33 within the stem 28 provides through radial ports 37 an inlet to the larger end of the intensifier cylinder and through ports 36 and a further bore 34 an outlet from the smaller end of the intensifier cylinder leading into the ram cylinder 10. A head 21 closes the larger end of the intensifier cylinder and has an internal recess 45 the mouth of which is engaged in the position shown by a packing ring 48 on a boss 47 secured to the end face of the piston 38. In operation a valve 52 is operated to connect an outlet 27 from the ram cylinder 10 to drain, and to supply pressure fluid to the bore 33 where it flows through ports 35 and 36 to displace the ram 23. An increase in pressure due to greater ram resistance acts on the boss 47 to move the stepped piston 38 against the springs 44 thereby closing the ports 35 and uncovering the full area of the piston to the pressure fluid. When the valve 52 is reversed pressure fluid passes to the ram inlet 27 to return the ram and stepped piston, fluid trapped between the recess 45 and the boss 47 passes out through a non-return valve 51.

Abstract: 1,045,483. Conveying solids in liquids; ejectors. MERZ & McLELLAN SERVICES Ltd. June 11, 1963 [March 22, 1962], No. 11043/62. Headings F1E and FIR. An arrangement for conveying slurry, for example water mixed with fly ash, sand or silt, in a generally horizontal direction includes a generally horizontal channel or trough and means for causing the slurry to travel along it in helical paths. Fly ash from a power station is transported by railway wagons 14, Figs. 1 and 2, to a siding 11. Flexible hoses 15, each having a valve 17, convey compressed air to the wagons 14 from a main 13 and thereby force the ash therein into flexible hoses 16 connected to ejectors 19. The ejectors 19 are arranged in pairs, each pair being associated with two wagons 14 and supplied with water from a high pressure ring main 12 through a valve 20 and a changeover cock 21, the cock 21 allowing the water to pass to one or the other ejector to entrain the ash therewith and form a slurry which is fed through a pipe 22 into a trough 10. The trough may be 200 feet long and arranged end to end with a second trough (Fig. 3) to form an unloading station approximately 450 feet in length, which station is capable of dealing with about 20 wagons at one time, the change-over cocks 21 being set, for example, to supply water firstly to the ejectors associated with the odd-numbered wagons 14 and then to the ejectors associated with the even-numbered wagons 14. The pipes 22 discharge the slurry below the fluid level in the troughs and in such direction as to cause helical flow therein, which flow may be assisted and agitated by water jets and compressed air jets placed between each pair of pipes 22. The helical flow may be further assisted by allowing the base of each trough to extend for more than the semi-circle shown. The inner surface of each trough may, at selected positions, be formed or lined with wear-resistant material. Each trough has one or more overflow pipes (not shown) and automatic make-up valves (not shown). Two pumps 30 each having a suction pipe 31 and placed at the centre of each trough 10 pump the slurry to a pipeline. Two stand-by pumps 32 are provided. The slurry may be discharged from the troughs by ejectors. In a modification (not shown) a trough is placed between two sidings, and the delivery pipes from the wagons enter the trough from both sides but with their ends close to the same wall of the trough.
