Title: Harold E Trumbull: Innovator in Particle Feeding Technologies
Introduction
Harold E Trumbull is a notable inventor based in Columbus, OH, with a significant contribution to the field of particle feeding technologies. He holds four patents that showcase his innovative approaches to conveying solid particles under varying pressure conditions. His work has implications in various industrial applications, particularly in gasification processes.
Latest Patents
Trumbull's latest patents include a method of feeding particles from a first region to a second region. This method involves conveying solid particles via an elongate tube from a supplying region at one pressure to a receiving region at a substantially different pressure. Movable sealing zones, which comprise mixtures of solid particles and liquid, contact the inner wall of the tube and are carried along with the particles when forced by a ram from the tube into the receiving region. While the particles and sealing zones are being conveyed into the tube, a gate or an auger at the receiving region may substantially seal it from the tube. Typically, the sealing zones are formed as thin disks or annular layers of fine coal particles and oil, where discrete coal charges are fed into a gasifier unit.
Career Highlights
Throughout his career, Trumbull has worked with prominent organizations, including Battelle Memorial Institute and UOP LLC. His experience in these institutions has allowed him to refine his inventions and contribute to advancements in particle feeding technologies.
Collaborations
Trumbull has collaborated with notable coworkers such as Dean F Poeth and Ronald F Hartung. Their combined expertise has likely enhanced the development and implementation of innovative solutions in their respective fields.
