Abstract: A torque transferring and monitoring device includes a coupling having a hub portion, a first rim portion, a first set of spokes radially extending between the hub portion and the first rim portion, a second rim portion spaced apart from the first rim portion and a second set of spokes radially extending between the hub portion and the second rim portion. The second set of spokes are axially spaced apart from the first set of spokes. A plurality of pins are fixed to the first rim portion. Each pin has a portion positioned in an aperture formed in the second rim portion. The pin is clear of the second rim portion when the coupling is in an unloaded state. The pin engages the second rim portion to transfer load between the first and second rim portions when a torque exceeding a predetermined magnitude is transferred through the coupling.

Abstract: A coupling between a driving and a driven shaft includes a rigid tube to which are attached by bonding, in axially spaced apart relation at least two flexible annular elements of elastomeric material, the annular elements being of various shapes; the outer periphery of each ring is bonded to an attachment ring which is attachable to a flange of a connecting hub with each hub mounted or connected to one the shafts; in one form the tube is split axially and is adjustably attachable to the periphery of the rings.

Abstract: The invention is a float platform for aquatic instruction and therapy for use in swim training facilities that includes three basic components, a frame and first and second flotation arms. The frame has a base platform with a first end wall, a second end wall and a back wall secured between the first and second end walls and extending above the base platform and cooperate to partially surround a user support area on the base platform. An unrestricted entry-exit is defined between the first and second end walls above a front edge of the base platform opposed to the back edge of the platform.
