Abstract: Stabbing accidents are prone to occur to people handling needles, for example when recapping a needle or when trying to remove a needle from a syringe. A device is provided for safe and automatic removal of a needle from a syringe aimed to prevent stabbing accidents. The device is arranged to grab hold of and rotate the needle of a syringe. The needle, after being rotate off the syringe is discarded into the device by releasing the grip on the needle. The device rotates two rotating gears relative to each other to move grippers towards the needle, and rotates the two gears together to rotate the needle relative to the syringe which may be held by the user.

Abstract: A method and apparatus for defining a spray pattern to reduce the variation in the metering, targeting, distribution, and atomization of the fuel output of a fuel injector. The fuel injector contains a closure member extending along the longitudinal axis of the injector. The closure member can be positioned contiguous to a seat to occlude fuel flow. A sealing radius is defined when the closure member is in this position. The closure member can also be positioned such that it is not contiguous to the seat, thereby permitting fuel flow. A plate is disposed proximate to the seat with a first and second face, the first face facing the seat. An inlet is located on the first face of the plate, and at least one chamber is disposed on the second face of the plate. The inlet and the at least one chamber are in fluid communication. An orifice disc is disposed in a confronting arrangement with the second face of the plate such that each chamber is located proximal to each orifice.
