Expert improved a lab prototype system into a commercial, reliable automatic concentration controller, which was used successfully in many textile finishing mills to control concentrations of chemical used for bleaching and for dye oxidation. Plant personnel operated it and performed routine maintenance.

Expert led the project of expanding a laboratory gas meter (mass spectrometer-based) into an automated continuous gas monitor, suitable for monitoring up to three gas components simultaneously if they are separable by mass. This required adding an ion pump to a mechanical vacuum pump system, along with a built-in oven for de-gassing.

Expert has created laboratory prototypes of semiconductor circulators, utilizing the Hall effect. This work was done using germanium samples, each equipped with six alloy-junction gold terminations. An electromagnet was also used. (Single crystal silicon was not readily available at the time.)
By adding Esaki diodes to overcome losses, a unidirectional passive transmission device was made and tested. Both of the above devices were published in IEEE publications, and one in the BSTJ.

Expert designed and built a production machine to apply electrets continuously to an open width nonwoven sheet, as part of a melt-blown production line. This involved designing the housing, the cabling, and the corona generators to accommodate 7,000 volt power, needed to create the electrets.

Helped a nonwoven manufacturer to develop an improved termination that would eliminate an undesirable corona discharge that was occurring frequently
where their high voltage feed terminated at their corona discharge bar.Helped a second nonwoven manufacturer eliminate a corona 'leak' inside a corona current metering panel.
Helped one of the above manufacturers develop a system to feed corona current to some twenty areas over a twelve foot distance. System had to be accessible for routine maintenance and component replacement.Trained 40 maintenance personnel (at a dog food production facility) in understanding and maintaining electrical control equipment, including contactor/relay circuits, programmable controllers, motors and motor controls. Only a half dozen of them had any prior electrical training.

Expert may consult nationally and internationally, and is also local to the following cities: Charlotte, North Carolina - Asheville, North Carolina - Gastonia, North Carolina - Augusta, Georgia - Athens, Georgia - Columbia, South Carolina - Greenville, South Carolina
