Abstract: This invention relates to a positive displacement pump which allows a liquid additive (such as liquid fertilizer) to be introduced into another liquid stream (such as water) and to be mixed in a constant proportion. One end of the pump can be connected to a faucet and the other end to a typical garden hose or other device. Water enters the pump through a faucet and is redirected (bent) by an upper stator which allows the water to rotate turbine vanes. The turbine is rotatably connected to a cam and the rotation of the cam moves pistons which allows liquid fertilizer to be drawn in from its reservoir. The liquid fertilizer flows through a tube and into one of two pistons. Then, the liquid fertilizer is dispelled through one of the exit tubes through the pumping action of the pistons. The water which was used to turn the turbine then combines with the liquid fertilizer as it comes out of the exit tubes and a water/fertilizer mixture is created.

Abstract: The spacer element (10) includes a central portion (16) and two end portions (18, 20). The spacer element is generally cylindrical in configuration and the two end sections are adapted to receive and hold a portion of radioactive seed elements (12, 14). The spacer element comprises two half-portions (22, 24) joined by a hinge element (26) positioned along a longitudinal edge of the spacer element. The two half-portions rotate about the longitudinal hinge element, moving from an open position, in which the radioactive seeds can be loaded by an operator into the spacer element, to a closed position, in which the radioactive seeds are held in the spacer element. A plurality of seeds and spacers can thus be conveniently assembled into a series string thereof for loading into a needle and subsequent insertion into the prostate.
