LawReader just ran across this news report from some twenty years ago. The scientist is the older brother of LawReader’s Senior Editor Judge Stan Billingsley.

GLM-33 : D-C Proportional Oven Temperature Controller Investigators at the University of Texas Medical Branch, Galveston, are conducting extensive research in the area of biochemical pol: lastants, The investigative effort requires the use of a constant temperature oven, Conventional A-C control methods, such a silicon controlled rectifiers, create excessive electrical noise, which interferes with other instrumentation being used for the investigation. A d-c powered, proportional controller capable of maintaining a constant temperature from 750 to 225% 0,20c was needed. Power consumption of the oven i s 25 to 35 watts full Soad, at 24 to 28 volts and 1 – 1.5 amps.

Upon accepting the problem, the SwRl BATeam initiated queries to the NASA centers. Mr. S. W. Billingsley, Goddard Space Flight Center, provided a simple, economical solution which would meet the problem originator’s specifications. Schematics of the GSFC design were obtained and the device fabricated as part of the tearn8s application engineering effort.
