Abstract: In a discharge valve device, a protuberance penetrates a vertical channel with a raised portion engaging a channel. Thus when an attempt is made to rotate a cylindrical body in the circumferential direction with a raised portion engaging a channel, contact between the protuberance right side surface and the vertical channel restricts rotational movement of the cylindrical body in the circumferential direction.

Abstract: A Toilet Flushing Apparatus Locking Nut System characterized by affixing a rigid rod to a securing nut that contains multiple rod receiving holes. The locking nut system maintains a secured position by means of resistance created when the rod contacts the toilet flushing apparatus's lifting arm, preventing rotational movement of the securing nut to less than 360 degrees. Multiple rod receiving holes within the body of the securing nut afford the ability to adjust the rod's position—to further reduce the securing nut's rotation travel to less than 360 degrees.

Abstract: A dual flush toilet system includes a mechanism (22) that permits the flush handles (82,84) to be placed at any location on the toilet tank (12) and even on the top (14) of the toilet bowl if desired. The dual flush valve itself preferably comprises a prior art mechanism (20) attached to a pair of exterior handles (82,84) by means of a cable and wire system (60,64). Rotation of an outer handle (82) causes the main float (42) to rise under the influence of first wire (60) thereby causing a small, or low, volume flush to occur. Pushing down on both handles (82,84) simultaneously causes a float lock (34) to rise which in turn allows a lower float (52) to lift and engage the bottom rim (150) of the float mechanism (20) thereby holding the mechanism (20) up longer and causing the entire contents of the toilet to flush thereby creating a larger volume flush.

Abstract: A method for repairing tissue of a selected organ from among heart, brain, liver, pancreas, kidney, glands, and muscles in a patient's body. Adult stem cells that have the capability to repair tissue of the selected organ are recovered by harvesting from the patient's body. The harvested stem cells are then intraluminally applied through a designated natural body vessel. During the time the stem cells are being applied to the targeted tissue downstream, the designated vessel or duct is selectively occluded to increase concentration and pressure of the applied adult stem cells by the vessel.
