Title: Fuel injector with pressure bleed-off stop
Inventor: DELANEY TIMOTHY E
IPC: F02M61/20
Filed: 1996-06-27
Abstract: A fuel injector (10) with a hydraulically actuated needle check (40) includes a fuel pressurization chamber (26) positioned between a low pressure fuel supply passage (33-37) and a nozzle supply bore (29). A portion of the low pressure fuel supply passage defined as a fluid supply chamber (36) is in direct fluid communication with the fuel pressurization chamber (26) via a bleed hole (50). A bleed pin (41) extends into the fluid supply chamber (36) adjacent the bleed hole (50). The bleed pin (41) is movable between a first position in which the bleed hole (50) is open and a second position in which a portion (52) of the bleed pin (41) closes the bleed hole (50) when the hydraulically actuated needle check (40) moves between its closed position and its open position, respectively. A supply valve (38) is positionned in the low pressure fuel supply passage (37) between the low pressure fuel supply chamber (36) and the fuel pressurization chamber (26) in order to prevent the back flow of fuel from the pressurization chamber (26) into the supply passageways. When in operation, the movement of the needle check (40) serves to open and close the bleed hole (50) at precise times in order to both produce pilot type rate shaping at the beginning of each injection event and cause the abrupt termination of fuel flow out of the nozzle (27) at the end of each injection event.

Title: Collapsible boating anchor
Inventor: NORCLIFFE JOHN BARRY
IPC: B63B21/24
Filed: 1997-03-15
Abstract: An easily resettable collapsible anchor comprises a spindle 10 connectible by a hole 12 at one end to a cable and having three flukes 14 pivotally connected to its other end. A cam surface 38 on each fluke contacts one end of a sleeve 26 which is located on the spindle by a multiplicity of spring-loaded balls 28 housed in the sleeve and engaging in a helical groove 24 in the spindle. The cam surfaces can displace the sleeve axially along the spindle against the action of the balls to allow each fluke to pivot from the operative position shown into a collapsed inoperative position when a pull greater than the normal working load is exerted on the cable. This usually requires use of the boat's engine. The anchor can be reset so as to bring the flukes back into operative position by simply screwing the sleeve along the spindle until it is clamped against the cam surfaces. A loose collar 42 which snaps radially onto the spindle and has an end-flange 44 is reversible end-for-end to lock the anchor against collapse if desired.

Abstract: A downhole rotary cutting tool (10) comprises a tubular body (12) and a pair of pivotally mounted blades (14,15) movable between a retracted position as in figure 4 and an extended position as shown in figure 1. The upper cylindrical portion of the body (12) contains an annular blade actuating piston (16), normally biased in the blade retracted position by a spring (18). The piston (16) is movable in response to elevated fluid pressure within the body (12). The lower face of the piston (16) is attached to the upper ends of two dowels (20,21) which extend through the body (12) and contact a cam member (22) which is axially movable on a rectangular body portion (24) extending below the cylindrical portion (12). The cam (22) includes two axially extending fingers (26,27) for engaging cam surfaces of the respective blades (14,15). The blades (14,15) are biased in the retracted position by respective torsion springs (32) and can pivot around pin (28). Increased fluid pressure causes piston (16) to act against spring (18) which in turn causes the dowels (20,21) to move downwards and cam against the legs of the blades pushing the blades (14,15) into the extended position. The angular extension of the blades (14,15) can be controlled by the variation of the fluid pressure. Drilling fluid can be injected through ports above and below the blades serve to assist the cutting action and carry cuttings to the surface.
