Patent for a new and improved nut lock. This design calls for a grooved nut and bolt to hold a pin between the two while the bolt is screwed onto the nut. Depending on whether or not the pin is in said grooves, the nut may or may not be removed from the bolt, which increases the worker's control over the nut and bolt and prevents unintended loosening.

An aerial radiological survey of the Superconducting Super Collider Laboratory and surrounding area, Waxahachie, Texas. Date of survey: July--August 1991
An aerial radiological survey was conducted over the Superconducting Super Collider Laboratory (SSCL) site from July 22 through August 20,1991. Parallel lines were flown at intervals of 305 meters over a 1,036-square-kilometer (400-square-mile) area surrounding Waxahachie, Texas. The 70,000 terrestrial gamma energy spectra obtained were reduced to an exposure rate contour map overlaid on a United States Geological Survey (USGS) map of the area. The mean terrestrial exposure rate measured was 5.4 {mu}R/h at 1 meter above ground level. Comparison to ground-based measurements shows good agreement. No anomalous or man-made isotopes were detected.
