An alignment system for aligning an ingot of semiconductor or solar-grade material is provided. The alignment system includes a mounting block for attachment to the ingot, an optical device for aligning a predetermined centerline of the ingot with a reference line, and adjustable supports configured for supporting the ingot on at least four support points and configured to adjust the position of the ingot. The mounting block is movable between a horizontal position and a vertical position.

System and method for aligning an ingot with mounting block

A method of aligning an ingot of semiconductor or solar-grade material with a mounting block includes supporting the ingot using adjustable supports, aligning a predetermined centerline of the ingot with a reference line using a laser, and attaching the mounting block to the ingot such that the predetermined centerline remains aligned with the reference line.

Methods for aligning an ingot with mounting block

Traffic control devices are employed for providing temporary delineation and demarcation of traffic lanes in order to guide the flow of traffic through detours, construction areas, and the like. Normally, ballasts used with traffic control elements have been bags containing a stabilizing material such as sand. Such traffic control elements are subject to improvement. They do not permit the stabilizing material to be spread uniformly across the bottom of the traffic control element. Sandbags become lodged against one side of the traffic control element during assembly, or they are thrown against one side on impact. And none of the stabilizing materials in use lend themselves to disassembly and transportation when the traffic control elements are moved to a new hazardous site. Such shortcomings are overcome by the improvement herein.
