Abstract: A conveyor mechanism conveys a powder along a path. A first camera device arranged above the conveyor mechanism detects movement of a recognizable feature on an upper surface of the powder over a period of time. A velocity of the powder can be determined based on the movement of the recognizable feature over the period of time. A device can be used to generate the recognizable feature. A first light-emitting device can illuminate the upper surface to aid detection of the recognizable feature. A second light-emitting device can project a contour line on the upper surface, and a second camera device can be used to detect a position of the contour line. A cross sectional area of the powder can be correlated based on the position of the contour line.

Abstract: An exemplary implementation of a powder product unloading and storage apparatus has a single, preferably sealed cabinet, such as a glove box, for holding, accessing, and unloading the contents of a drum into the cabinet, wherein the cabinet includes a system for minimizing, ameliorating or eliminating the release of dust to the atmosphere. A rotary spout dispenses and directs the product entering into the cabinet to a preselected storage hopper which has been selected from a plurality of storage hoppers. The plurality of storage hoppers are preferably all held within a closed or filtered environment such that release of product to the atmosphere is reduced, ameliorated, or eliminated.
