Abstract: An apparatus and method for cleaning a lens system utilizes a rotating turntable that sequentially moves a plurality of lenses parallel to a shielding plate from a preexposed position to an exposed position located adjacent an aperture in the shielding plate. The apparatus includes a first manifold for directing a first flow of gas across a surface of a lens located at the preexposed position, and a second manifold for directing a second flow of gas across a surface of a lens located at the exposed position. First and second vacuum nozzles remove, respectively, airborne particles within the first and second gas flows. An additional nozzle mounted adjacent the aperture provides an ionized gas.

Abstract: A device for locating and orienting objects at a precise location includes a lever pivoted to a fixed support. The lever supports a first urging member arranged at a first preselected distance from the pivot axis. A second urging member is pivoted to the lever at a second predetermined distance from the pivot axis. Pivoting of the lever causes the urging members to urge the object into the desired precise location and orientation.

Abstract: An apparatus for centering a deflection yoke in a support ring includes a spindle having a tapered portion and a cylindrical portion. A spider, having radial arms, is centered on the spindle. A planar member includes an inset which is centered on the spindle, and is supported on the radial arms. The inset centers the support ring on the spindle. The tapered portion centers a yoke on the spindle whereby the yoke is centered in the support ring. Holding members are in the support ring, and hold the yoke centered in the support ring.
