Abstract:
1. A filter support casing and filter for providing powder into a Bernoulli flow system, the filter support casing and filter comprising: an upper end and a lower end, the upper end having an opening therein; a filter support casing extending downward from the upper end; a filter supported within the casing; the filter support casing and the filter defining an internal volume within both the filter support casing and the filter; the volume exposed to the opening in the upper end; the casing comprising two concentric elements, a first inner elements and a second outer element, that rotate with respect to each other and which slide with respect to each other; the first inner element contiguous with the filter, and enclosing the filter with arms extending from a top of the first inner element to a bottom of the first inner element, the arms providing an open area between arms between the top of the first inner element and the bottom of the first inner element; the second outer element in sliding and rotating relation with the first inner element and enclosing the first inner element with arms extending from a top of the second outer element to a bottom of the second outer element, the arms in the first inner element providing an open area between arms between the top of the second outer element and the bottom of the second outer element, wherein relative rotation between the first inner element and the second outer element alters gas pressure between the first inner element and the second outer element.
