Direct indication of particle size in fluidized beds
Differential pressure measurements indicate particle size and particle size distribution in fluidized beds. The technique is based on the relationship between bed particle size and the intensity and frequency of fluctuations. By measuring the fluctuations, an estimate of average particle size of the fluid-bed material can be made.

Circuit counts pulses and indicates time of occurrence of slow pulses
Counter includes one section which counts the first several pulses, and a second section which counts pulses from a clock between the beginning of a sampling interval and the receipt of the first pulse by the circuit. The number of clock pulses indicates receipt time of the first pulse.

Simple test indicates degree of cure of polyimide coatings
Qualitative test involves immersing a coated cable in methyl-2-pyrrolidone and removing it in one to three minutes. Evidence of any cracking, peeling, or other defects that shows under 20-power magnification indicates that the coating has not been completely cured.
