Expert in Process Control; Motor Synchronization & Control; Machine Control; Corona Generation (high voltage)
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
