Abstract: A specimen package includes a top, a first side, connected to the top, a bottom, connected to the first side, and a second side, connected to the bottom. The package also includes therein an internal separator. The internal separator forms a first compartment and a second compartment within the package. The top includes a window for viewing the first compartment. The bottom includes a second window for viewing the second compartment. The top, the first side, the bottom, the second side, and the internal separator can all be formed by folding a shaped planar sheet. The first compartment can contain a specimen, placeable within the first compartment. The second compartment can contain a label, placeable within the second compartment. The specimen is viewable through the first window, and the label is viewable through the second window.

Abstract: A guide structure is provided for guiding the flow of particulate matter from a source to a distribution manifold. The guide structure includes a generally tubular elbow defining a flow path for the particulate matter. First and second veins are positioned within the elbow so as to lie in the flow path in the particulate matter. A flow tube is positioned between the output of the elbow and the distribution manifold. A forcing cone is positioned within the flow tube adjacent the output thereof to reduce the inner diameter of the flow tube and to increase the velocity of the flow of particulate matter therethrough.

Abstract: A pneumatic seed delivery system is provided, including a bin with a plenum at the bottom separated from the bin by a membrane to permit the upward flow of air from the plenum into the bin, and a tube extending through a side wall of the bin to provide fluid communication from an outer surface of the bin to an inner surface of the bin. One end of the tube is disposed inside the bin and adjacent to the screen, and a second open end of the first seed distribution tube is disposed outside the bin. In this manner, seed in the bin can be propelled up the tube by forcing air into the plenum, passing the air through the membrane and through seed located between the membrane and the first open end of the tube. This seed will then move up the tube and be carried to a remote location for use.
