Abstract: In a personal recreational watercraft, an improvement resides in a suspension mechanism, which permits greater maneuverability and stability, and reduces driver fatigue. To overcome the strong forces, a suspension system is employed which permits up and down vertical movement, while resisting lateral movement and torsional forces. The suspension apparatus also reduces shock effects caused by choppy or rough water.

Abstract: A basin for simultaneous or consecutive dewaxing and curing of denture molds is disclosed. The basin is generally box-shaped and is provided with three vertically-shaped trays of which the topmost remains above the high fluid level. The upper rear portion of the basin has a pivotally-secured frame-arm provided with a plurality of nozzles adapted to spray over the entire area of the topmost tray. The fluid from the nozzles drains back into the basin; a recirculating pump recirculates the fluid back into the nozzles. A separate fluid inlet is provided to fill the basin for curing. The basin is further provided with an upper and lower fluid level-limiting means, a heating element, a thermostat and, preferably, an automatic timer.
