  • Patent number: 6641019
    Abstract: A fastener driving tool includes a magazine comprised of a plurality of fastener slides, each of which carries a fasteners of a different size. The magazine is designed so that an operator may to choose to drive fasteners from any of the fastener slides. In one embodiment, the fastener slides are arranged around a central core. A rod supported by the tool's base and driver fits within the central core and provides an axis of rotation for the magazine. During rotation of the magazine, each slide can be aligned with the driver. Alignment of a slide is maintained by a position locking means. A feed means in each slide forces the fasteners down the slide and into the driver. In another embodiment, the fastener slides are arranged next to one another in the magazine. Each slide can be aligned with the driver by shifting the magazine laterally. A position locking means keeps the magazine in the proper alignment once a particular fastener slide has been chosen.

  • Patent number: 6602464
    Abstract: A method and apparatus are provided for minimizing the emissions of odorous gases and fatty acids generated by digestible and odiferous waste. The apparatus includes a treatment comprising oil, activated carbon and a base buffering agent. The apparatus also includes a system for delivering the treatment through a low pressure output, such as a low pressure manifold with a plurality of delivery pipes. A starter plank made of concrete, used for mounting the apparatus on a wall and a flotation board, made of foamed polystyrene board, directs the flow of the treatment onto the surface of the waste. The method includes the steps of applying oil and activated carbon to the surface of liquid waste and injecting a base buffering agent below the surface of the oil/activated carbon layer. The oil and activated carbon create a seal that prevents odorous emissions from entering the air space above the liquid waste and the base buffering system neutralizes the acidic waste.
