Use of acrylic sheet molds for elastomeric products
Molds constructed of acrylic sheet are more easily machined than metal, are transparent to ensure complete filling during injection, and have smooth surfaces free of contamination. Technique eliminates flashing on molded parts and mold release agents.

A method for the visual detection of holes in thin polymeric films
Back-lighting polymeric film with polarized light from a polarizing plate and viewing it through a second plate cross-polarized to the back-lighting provides visual contrast between the flaw and the transparent film.

Investigation of an Optimum Detection Scheme for a Star-Field Mapping System
An investigation was made to determine the optimum detection scheme for a star-field mapping system that uses coded detection resulting from starlight shining through specially arranged multiple slits of a reticle. The computer solution of equations derived from a theoretical model showed that the greatest probability of detection for a given star and background intensity occurred with the use of a single transparent slit. However, use of multiple slits improved the system's ability to reject the detection of undesirable lower intensity stars, but only by decreasing the probability of detection for lower intensity stars to be mapped. Also, it was found that the coding arrangement affected the root-mean-square star-position error and that detection is possible with error in the system's detected spin rate, though at a reduced probability.
