Abstract: A method of fusing a joint between two bones, comprising boring a hole through one of the bones across the joint therebetween and into the other bone, placing the leading end of a screw into the hole, where the screw has a threaded region having a pitch that is larger toward a leading end of the screw and smaller toward a trailing end of the screw, and driving the screw into the bone until the threaded region spans the joint.

Abstract: A dunk tank seat release mechanism is disclosed including a support that is disposable proximate the rear of a dunk tank. A seat is hingably attached to the support and is alternatable between generally horizontal and collapsed positions. A releasable gripping mechanism holds the seat in a generally horizontal position and includes a pair of opposing, pivotably interconnected stationary and movable jaws. A stationary handle is fixed to a stationary jaw and a movable handle is pivotably attached to the movable jaw. The jaws are biased closed when the movable handle is closed relative to the stationary handle to hold the seat. An actuator member extends between the stationary and movable handles generally laterally of the tank. The actuator member has a thickness between the handles such that a spacing of at least 3/8" is provided between the actuator member and the movable handle. A target is mounted to the actuator member to face generally forward of the tank.
