Abstract: The clear chaffer fuel canister of the present invention allows the users to determine the hours of burn time remaining in relation to the volume of fuel remaining. Visual indicators on the clear base vessel correspond to the predetermined burn time remaining. The volume of fuel, as it reaches the visual indicators provides the user a quick and reliable means of determining the burn time remaining with the clear chaffer fuel canister. The burn time remaining is an essential feature, as clear chaffer fuel canisters are generally used in the food industry in maintaining the proper temperature of prepared food. The burn time remaining provides an indication to the users and allows the users to determine the optimal time to replace the clear chaffer fuel canister and maintain the appropriate temperature of the displayed food.

Abstract: An improved shear cutting blade comprising a plurality of opposing countersunk fastener holes and four cutting edges is disclosed. Four cutting edges and two mounting surfaces are provided, along with threaded, countersunk holes to allow fasteners to secure the blade in multiple orientations. The blade is ideally utilized in a compacting and baling process, wherein loose scrap metal and other material are pressed from a collection point and into a compaction chamber, wherein the blade is passed over the material as it is pressed into the chamber, shearing the debris into a compact, baled form. The blade can be rotated and secured against either mounting surface, and rotated to allow use of any of its four cutting edges, providing reusability and improved service life of a single blade during operation.
