Title: Armistead M Long: Innovator in Bulk Material Sampling Technology
Introduction
Armistead M Long is a notable inventor based in Knoxville, TN (US), recognized for his contributions to the field of bulk material sampling technology. With a total of 3 patents, Long has developed innovative solutions that enhance the efficiency and accuracy of material sampling processes.
Latest Patents
One of Long's latest patents is the "Control system for belt sample cutters." This apparatus is designed to extract cross-sectional samples of bulk material from a moving belt conveyor using a rotating sample cutter. The sample cutter is driven around a circular sampling path by a pair of double-acting pneumatic cylinders, which are connected to angularly offset crank throws. The fluid flow in and out of each pneumatic cylinder pressure chamber is independently regulated based on the respective cylinder rod position and direction of movement. This allows both chambers to be simultaneously open to the pressure supply or to the atmospheric vent for a brief rotational arc.
Another significant patent is the "Belt conveyor cross-stream sampling system." This method and apparatus provide a means for cross-stream sampling of bulk material distributed as a mounded continuum in a trough formed along the length of a belt conveyor. A rotating cutter passes transversely through the traveling bulk material continuum to extract nearly all material on the belt in a swath between transverse, parallel cutting planes. Rigid skirting is provided to overlay both lateral edges of the belt, ensuring full surface contact by the cutter and maximizing small particle retrieval.
