  • Patent number: 8845898
    Abstract: An auxiliary power unit includes a gearbox housing portion and a filter housing portion providing an integral housing. A filter cavity is provided in the filter housing portion. A surface circumscribes the filter cavity. A scupper includes a passage extending from the surface to an opening on an exterior surface of the integral housing. A sealing region between the scupper and the filter cavity is configured to fluidly isolate the scupper and the fuel filter cavity from one another. In one example, the filter cavity receives a fuel filter cartridge. A cap is secured to the filter housing portion and encloses the filter cavity when in a secured position.

  • Publication number: 20100175300
    Abstract: An interactive, mobile decoy system uses a bent wire framed assembly with two parallel support runners which transition rearward in an 180 degree arc toward the center of gravity of the support runners and terminate at a junction block. The block joins a support mechanism with a decoy attaching point. A pull mechanism incorporates a pivoting decoy mounting point for causing a decoy mounted thereon to realistically simulate the feeding motions of game fowl in general and wild turkeys in particular, especially a strutting motion of a male and a feeding behavior of a hen.
