Patent GB-2008653-A (GB)
Title: Method of Driving Sheet Piles into a Rock Substratum
IPC: E02D17/16
Filed: 1978-10-13
Abstract: Problems arise when erecting a sheet pile on rock substratum and subsequently anchoring the piles. If a channel is blasted, this has the draw- back that the over burden has to be initially cleared prior to blasting and then replaced subsequently. In addition, the piles when secured in the blasted channel when refilled with concrete and the anchors in the rock substratum are not as securely supported as piles driven into normal substratum. A method of erecting sheet pile and a method of anchoring the sheet pile is disclosed where the substratum is shattered by blasting sufficiently to allow the piles and the anchors, which are also piles, to be driven into the rock substratum. Each method involves drilling bore holes 2 and inserting a water tight charged container 10 into these and determining the volume of charge 12 relative to container volume such that the rock substratum 6 surrounding a bore hole after detonation is not significantly damaged in its external form but has a shattered internal structure allowing pile driving. <IMAGE>

Patent GB-2019043-A (GB)
Title: Pressure Operated Hydraulic Control Valve
IPC: F04B1/29
Filed: 1979-04-05
Abstract: A pressure operated control valve operative to regulate the flow of fluid to an hydraulic modulating cylinder having a fixed hydraulic bleed which cylinder operates a mechanism for varying the displacement of a compressor of an automotive air conditioning system to maintain a predetermined control or system pressure. The system pressure continually surrounds a sealed bellows 330 seated in the closed end of a tubular bellows cover 310. High pressure fluid is continually supplied to the control valve which has a ball 385 and seat totally to restrict fluid flow to the modulating cylinder when the system pressure exceeds the setting pressure of the valve. When the system pressure drops below the setting pressure, the bellows extends against an axial pin 348 which forces the ball from its seat, thus allowing high pressure fluid to flow to the compressor modulating cylinder operating the compressor mechanism and reducing the stroke of the compressor pistons. When the system pressure returns to the setting pressure, the bellows retracts moving the ball toward its seat thereby reducing the hydraulic fluid flow to the modulating cylinder. <IMAGE>
