Abstract: An apparatus for coating the surface of a lens includes a carousel having a central hub and a plurality of arms. A drive shaft is mounted to each arm, with a magnetic clutch and a lens holder being operatively attached to the drive shaft. The carousel is configured to be raised, rotated, and lowered into a series of workstations for processing the lens in a predetermined sequence. A workstation has associated therewith a spin drive attached to a reciprocating arm assembly. The spin drive includes a magnetic clutch which may be coupled to the magnetic clutch of any one of the arms on the carousel, such that a rotation generated by the spin drive is transferred to the drive shaft, and the lens holder. The arm assembly is capable of being extended and retracted to selectively engage and disengage the carousel.

Abstract: The present invention relates to a decorative water display having many degrees of freedom. The water display has one or more water display nozzles mounted so that the direction of the nozzle may be controlled such as by a computer. In the preferred embodiment, the pressure of the water delivered to the nozzle may also be controlled as desired. Also controllable with the nozzle direction is appropriate lighting to illuminate the discharge from the nozzle for night time use. The elevation of the entire assembly is controllable, preferably between an operative position, a withdrawn position totally below the water surface and a service position extending above the water surface. Various embodiments and features are disclosed.

Abstract: A ring blade and drive system, and method of using same, for harvesting bone-tendon-bone ligament grafts having substantially cylindrical bone plugs. The ring blade disclosed is a circular ring having a predetermined arcuate gap formed in its periphery. The drive system includes a blade holder to peripherally hold the ring blade and a fixed-center oscillating mechanism to oscillate the ring blade about its axis within a predetermined arcuate range of motion. The ring blade structure enables the production of a substantially cylindrical bone plug of unlimited length. Harvesting of a bone-tendon-bone ligament graft is facilitated with the ring blade and method disclosed which enables the ring blade to be placed partially around a tendon segment to create bone plugs aligned with the tendon fibers included in the defined tendon segment. The cuts into the bone may be initiated into the bone at either end of the tendon segment from the tendon side through to the exterior of the bone to which the tendon is attached.
