Flight reentry experiments define the total heating on a large blunt-nosed body by means of imbedded thermocouples. The thermocouples, installed in a beryllium layered forebody, were designed to provide minimum feasible disturbance of local heat flow with accurate depth control of the thermocouple junction locations.
Algesimeter which incorporates a standard sensory needle with a sensitive micrometer, measures needle point depth penetration in pain tolerance research. This algesimeter provides an inexpensive, precise instrument with assured validity of recordings in those biomedical areas with a requirement for repeated pain detection or ascertaining pain sensitivity.
Study determines optimum fastener insert size and shape, type of embedding cement, diameter, undercut and depth control by fiber glass plug in a honeycomb structure for maximum tensile strength The best potting compound is 5-5-1 weight mixture of epoxy resin, curing agent, and milled glass fibers.

Hydrogen-oxygen rocket engine used to test acoustic liner with isolated resonators and variable cavity depths
Effects of shallow liquid depths on lateral sloshing in cylindrical tanks under weightless conditions
Computer program for finite difference equation analysis of in-depth response of materials exposed to high temperature environment
Junction depths measurement in semiconductor devices by drilling with rotating sphere
Energy deposition by monoenergetic unidirectional proton beams incident on polystyrene phantom, obtaining centerline depth dose curves
Simulated low gravity liquid sloshing in cylindrical tanks, emphasizing small liquid depth and smooth wall viscous damping effects
Mafic and ultramafic inclusions as clues to depth of origin of basaltic magmas in earth mantle, noting estimation of geothermal gradients
Imaging technique for generating holographic depth range contours
Microwave interferometer system controls the cutting of plastic materials to a prescribed depth. The interferometer is mounted on a carriage with a spindle and cutting tool. A cross slide, mounted on the carriage, allows the interferometer and cutter to move toward or away from the plastic workpiece.
