Abstract: INTERFEROMETRIC METHODS FOR DEVICE FABRICATION Abstract The invention involves new etch monitoring and thickness measurement techniques which are more accurate than previous techniques.  In accordance with the invention, the etch depth of a substrate region undergoing etching is monitored, or the thickness of the region is measured by impinging the region with light and detecting the intensity of the reflected light.  In contrast to the previous techniques, the incident light is chosen so that a substrate region underlying, and/or a patterned substrate region overlying, the substrate region of interest is substantially opaque to the incident light, which precludes the formation of signals unrelated to etch depth or thickness.

Abstract: Abstract of the Disclosure Apparatus and Method For Turning a Track Bushing Apparatus and method of turning a bushing of a track chain link assembly is disclosed which enables the bushing to be turned in place in the link assembly, thereby eliminating the need to disassemble the link assembly in order to effect the bushing turn.     The apparatus includes clamping means having three jaws for clamping the bushing, each of which has a deformable insert of an aluminum alloy so that, upon application of the clamping force, the shape of insert can change to accommodate one-sided sprocket wear on the bushing and insure intimate clamping contact therewith.  Each of the deformable inserts is supported on an arcuate surface of a support block which has apertures and grooves for providing space into which material of the insert can extrude to facilitate the ability of insert to conform to the bushing.         The grooves are oriented longitudinally so as to provide a mechanical interlock between the insert and the support blocks, thus eliminating any slippage between the block and insert as the links are being rotated.

Abstract: ABSTRACT     Provided is a pipe end protector for protecting the threads and end face of a pipe end.  The pipe end protector comprises a substantially open-ended metal sleeve and a cast polyurethane liner chemically bonded to the surface of the sleeve closest to the threads.  The liner is configured, dimensioned and contoured during the casting thereof so that the surface of the liner facing the threads threadedly receives such threads.  The sleeve is provided with a radially extending annular end face portion for covering the end face of the pipe.  The liner is provided with a radially extending annular end face portion for bearing against the end face of the pipe end.  The pipe end protector of the present invention is particularly suited for use during mill operations, since it allows for both hydrostatic pressure testing and drift testing with the protector in place.  Also provided is a pipe end closure for protecting against ingress of foreign material such as snow.          The pipe end protector can be adapted to protect pipe ends having either external or internal threads.
