20080249550 | Miniature disposable safety scalpel - A disposable safety scalpel comprises a handle and a blade carrier, which fit together such that the blade carrier can shift between a retracted position whereby a front portion of the handle covers or otherwise blocks contact with the sharp edge of the blade, and an extended position whereby the sharp edge of the blade protrudes beyond the handle. The handle has a substantially flat base portion that can be held by the forefinger of the surgeon for shifting of the carrier with the thumb between retracted and extended positions. When the carrier and blade are extended, the surgeon can hold only the base of the handle between the thumb and forefinger for cutting during surgery. The shifting between the retracted and deployed positions with only the fingers of one hand can be readily accomplished even in the presence of slippery fluids during surgery. | 10-09-2008 |
20090208355 | Radial piston fuel supply pump - A high pressure radial piston fuel pump is featured having an hydraulic head with two individual radial pumping pistons and associated pumping chambers, annularly spaced around a cavity in the head where a rotating eccentric drive member with associated actuation ring are situated. A rolling interaction is provided between the actuation ring and the inner ends of the pistons for intermittent actuation. Relative rotation is provided between the actuation ring and the drive member. Each piston has a piston bore that has a centerline that intersects the actuation ring but is offset (X) from the drive axis as viewed in cross section perpendicularly to the drive axis and the piston bore centerlines are parallel to each other but offset (Y) from each other as viewed in longitudinal section along the drive axis. | 08-20-2009 |

Also, a safety biopsy instrument with a handle, body and removable blade cartridge with a distal opening, a tubular blade having a sharp edge, and a resistance member disposed between a front shoulder and rear wall to bias the blade edge away from the distal opening. Forward movement of the body relative to the handle causes the resistance member to compress between the rear wall and front shoulder and the blade edge to travel distally. | 02-18-2010 |
20110054398 | Medical syringe with retractable needle - A piston in a syringe barrel has a cavity that opens toward the distal end of the barrel. A needle assembly has a hub, a hollow needle fixed in the hub, and a spring seated between the distal end of the barrel and the hub. A membrane is between the hub and the opening of the piston. A locking member is lodged between the barrel and the needle assembly, holding the needle assembly within the barrel to compress the spring. The piston is displaceable through functional positions in which the piston (a) forces serum out through the needle, (b) urges the membrane against the hub, and (c) dislodges the locking member thereby releasing the needle assembly such that the spring displaces the hub and at least a portion of the membrane into the cavity and withdraws the needle tip into the distal end of the barrel. | 03-03-2011 |
20110126804 | Common rail fuel pump with combined discharge and overpressure relief valves - A high pressure piston fuel pump having a discharge check valve between the pumping chamber and a pressurized fuel reservoir and a pressure relief valve between the fuel reservoir and a passageway in the housing, wherein the discharge check valve and the pressure relief valve are contained within a single fitting assembly affixed at the pump housing. A first end flow passage is in fluid communication with the pumping chamber and provides an inlet to the discharge check valve and an outlet from the pressure relief valve. A second end flow passage is in fluid communication with the fuel reservoir and provides an outlet for the discharge check valve and an inlet for the pressure relief valve. Advantages include the ability to pre-test the outlet check and pressure relief prior to assembly into the pump housing, and improved flexibility of the outlet fitting location. | 06-02-2011 |
20110303195 | Single piston pump with dual return springs - Pump piston seizures caused by excessive side loads produced by the uneven loading of a large piston return spring are prevented by separating the tappet return function from the piston return function, thereby minimizing the spring force acting on the piston. Separate and distinct biasing means perform the respective functions. Preferably, a stronger, heavier load outer spring is mounted between the pump body and the tappet, such that it imparts no load and therefore no side loads to the pumping piston. A weaker, lighter load inner spring imparts less side load to the pumping piston than a conventional piston return spring, because the inner spring need not carry any tappet load. During both the pumping and charging strokes of the piston, the piston return spring can assist the tappet return spring, but the tappet return spring does not assist the piston return spring. | 12-15-2011 |

20150339245 | Adaptive Scheduling Queue Control For Memory Controllers Based Upon Page Hit Distance Determinations - Methods and systems are disclosed for adaptive scheduling queue control based upon page hit distance determinations. A threshold occupancy value is determined for a window of previous access requests to a memory and used to adaptively control a number of access requests stored in a scheduling queue buffer. For certain embodiments, a page hit distance (PHD) determination for each access request and historical page hit distance data is used to adjust the threshold occupancy value that determines the number (N) of access requests stored in the buffer prior to removing an access request and using it to access the memory. For each access request, the page hit distance represents the number of previously received access requests since the last access request to access the same page of memory. An average PHD can be determined over a number (M) of previous access requests and used to control the threshold occupancy value. | 11-26-2015 |
