Abstract: A reusable spacer tool comprises a pair of opposed spacer members each having a plurality of ears projecting from a base portion toward the opposite member, the ears being arranged for reception in the joints between adjacent blocks to space apart edges of the blocks when the spacer members overlie opposite faces of the block at the corners, and tie means extending between the spacer members and removably secured thereto releaseably hold the members against opposite faces of the blocks.

Abstract: An illumination system particularly useful for inspecting a workpiece by an optic scanner includes darkfield illumination produced mainly by two elongate light sources each having a reflector focussing member and a lenticular lens sheet spreading the light from its light source over its reflector focussing member to produce an approximate image of its light source on the line to be scanned. The illumination system further includes brightfield illumination produced mainly by a third elongate light source mounted laterally of the scanner optic axis, a refractive focussing member, and a further lenticular lens sheet producing an approximate image of the third light source on the line to be scanned. A beamsplitter aligned with the scanner optic axis reflects the light from the refractive focussing member towards the workpiece, and conducts therethrough both the darkfield and brightfield illumination reflected from the workpiece to the optic scanner.

Abstract: An apparatus for cutting glass produced in a continuous flow process is disclosed. The apparatus includes a cutting and/or scoring means, a linear step motor means, a rail means, an actuator for elevating a cutting and/or scoring means, and a control means. The apparatus will position the cutting means accurately and quickly, because the linear step motor is utilized and, thus, the amount of cullet will be reduced.

Abstract: A method and apparatus for progressive user interactive exercise of the eyes, utilizing a computer connected to a computer display terminal having a screen, featuring Eye Movement, Fusion and Focusing Exercises and Apparatus that can be used separately or as a single unit. The Eye Movement and Fusion Exercises and Apparatus, therefore, have the option of giving the user a quantitative result indicating the user's level of accomplishment. The Eye Movement and Fusion Exercises offer a range of progressively more difficult choices. The quantitative results can be weighed to give a higher or lower score, depending upon the level of difficulty chosen for an exercise, and can also be cross-referenced with other responses to form reports.

Abstract: An axle suspension system for a wheeled vehicle is disclosed. The system includes a frame, a frame connection member, a beam assembly, a torque box and an air bag connection. The beam assembly is lightweight, cost effective, and efficient because the beam assembly utilizes a box beam structure in conjunction with the torque box structure which provides for substantially even distribution of axle deflections throughout the entire beam assembly.
