The device includes wedge component having an outer surface contacting the inner surface of a rim and a tapered inner surface contacting a similarly tapered surface of the spindle, is displaced axially relative to the tapered surface of the spindle. Such axial displacement is translated into a radial displacement of the wedge component as a consequence of the wedge effect between the tapered surface of the wedge component and tapered surface of the spindle. If the wedge component is displaced radially outward, its outer surface pushes against the inner surface of the rim and the rim is clamped through the frictional force between the inner surface of the rim and the outer surface of the wedge component.

Abstract: An improved apparatus for manually manipulating a surgical laser beam is disclosed. The preferred embodiment of the invention includes a mirror nominally positioned at a 45 degree angle to the incident laser beam, a joy stick for manipulating the mirror, and a linkage interconnecting the two. The mirror is mounted to allow it to rotate about two mutually perpendicular and intersecting axes. The linkage operates to direct the reflected laser beam in two orthogonal dimensions such that a ratio between the movement of the reflected beam in each dimension is equivalent to the ratio of the movement of the joy stick in each dimension. This yields a reflected laser beam that moves a distance proportional to the amount of motion input to the joy stick. The reduction or amplification ratio between the input motion and the reflected laser beam motion remains constant, regardless of the direction of motion.

Abstract: A shock absorber mount is described as having two pressed fittings which are mounted in end-to-end relationship. Each insert has two rigid, radially spaced cylindrical sleeves which are separated by a resilient rubber insert. The inner sleeve of the vertically lowermost fitting, when the fittings are properly mounted on, for example, an automobile frame, extends upwardly beyond the associated outer sleeve and is coated with rubber to enter a hollow bore formed by the inner sleeve of the upper fitting. The extension allows the lower fitting to initially absorb an upwardly applied axial force until it moves into shock absorbing relation with the upper fitting. The extension also acts to bolster the radial shock absorbing characteristics of the upper fitting to provide improved shock absorbing characteristics of the mount; namely, low axial shock absorption and high radial shock absorption.
