  • Patent number: 6003711
    Abstract: A drink through cap that removably attaches to a drinking cup or mug. The cap has a plate-like body with a drink through hole. A raised edge extends upwardly from the periphery of the body. A disk-shaped insert is rotatably supported on the body and has a drink through area that can be aligned with the drink through hole in the body for drinking and unaligned to prevent spilling. Tabs fixed to the insert extend over the raised edge of the body where they can be rotated to the raised open stop to align the holes for drinking, or rotated to the closed stops for nonalignment of the holes for safety. Further, the tabs can be placed over the open stops to provide a latched open condition and can be placed over the closed stops to provide a latched closed condition.

  • Patent number: 5050510
    Abstract: An apparatus and method of burning trash containing aluminum in a furnace having a moving grate and inclined trays. The grate has an upper and lower part. The inclined trays are provided with one or more inclined plates. The inclined plates are supported on the trays below the upper part of the grate and above the lower part of the grate. Ash and molten aluminum falls through the upper part of the grate, onto the inclined plates, the ash slides off the plates and the aluminum remains on the plates. The plates have holes therethrough to allow air flow for combustion. Some blockage of the holes by aluminum will result over time, but not enough to significantly restrict the flow of combustion air to the combustion area. The trays are removed through the side walls of the furnace for removal of the aluminum when necessary.
