Abstract: An apparatus for the control of fluid flow through a valve. A single shaft-mounted cam moves translationally along the length of the shaft, stopping sequentially at positions adjacent to and in operative engagement with an actuator disposed on or near a valve body. Once in position with a predetermined valve, the cam, which is also coupled to a rotational member, is rotated, thus causing an eccentric portion of the cam to engage the actuator in such a way so as to force the valve to open or close. A flow detection system is integrated into a main fluid transport conduit, allowing sensed flow variations to be sent to a controller. The controller uses a comparison algorithm to determine what fluid settings in the valve are necessary to effect a desired fluid flow through the valve, and prepares an input signal to be sent to one or more motors controlling the translational and rotational motion of the cam.

Abstract: Snow skis having asymmetrical edges to make turning easier while telemark or alpine skiing. Each ski has concave, curved lateral edges. These lateral edges are asymmetrical, in that the medial edge of each ski is substantially longer than its outer edge. In addition, the point of maximum side cut on the outer edge is adjacent to the toe area of the skiers boot, while the point of maximum side cut on the medial edge is adjacent to the middle of the ski boot to facilitate easier turns while telemark skiing.

Abstract: The present invention provides a molded boat hull with a novel structural stiffening system. The boat hull has a number of laterally positioned compartments molded into the inner shell with vertical partitions that are integrally welded to the outer shell and are interconnected to each other and to the transom. A keel plate and a transom support are molded into the transom, the inner wall, and a bridge along the longitudinal center line of the boat. A keel support beam is placed along the keel, connected to the keel plate, and adhered into a channel in the boat hull inner shell. A pair of stringer braces is assembled between the integral stringers to provide transverse stiffness of the boat hull.
