  • Publication number: 20100123067
    Abstract: A deployable and stowable bow caddy has an upper support section with a pair of horizontal members for supporting a bow without damage to any delicate components extending from the bow. The upper support is supported by a lower section which may be sub-divided into further smaller sections for more convenient storage and carriage. The support components may preferably be hollow tubular construction for strength and light weight. The handle sections will preferably be coated with a protective elastomeric coating which will not only prevent any damage to the bow, but will prevent the bow from sliding while the bow is being supported.

  • Publication number: 20100123056
    Abstract: A deployable stowable shotgun/rifle rest & fishing rod holder includes a common lower section which may preferably be hollow tubular construction and having a pinched tip for resistance to any deformation upon being inserted into the soil, and two upper sections which are not expected to be simultaneously needed, one section for a shotgun/rifle rest and one section for a fishing rod support, enables greater utilization of the common lower section.

  • Patent number: 6516697
    Abstract: An improved spent shell carriage container, storage and dispensing hopper system provides two structures which can be added to a standard sized bucket, one structure through direct mounting and the other through drop insertion, to produce a spent shell carriage container and dispensing hopper. The direct mounting structure is simply a latch to hold a lower portion of the drop in structure in the closed position. The drop in structure includes a first member which can be shaped to gather support from the inside of the bucket to provide an angled approach to a second member acting as a door. The second member is sized as a partial cup to prevent, limit and stabilize the spent shells appearing and passing through the opening so that a hand sized accumulation will be available for quick manual engagement and loading on the reloading equipment.

  • Patent number: 6305406
    Abstract: A spray hood device for containing a fluid spray leak in a fluid-based cooling system. A cover member surrounds a given component subject to a fluid spray leak, containing fluid sprays, preventing the fluid sprays from reaching equipment therebelow and minimizing fluid leakage damage.

  • Patent number: 5975114
    Abstract: A system, method and apparatus for detecting a fluid leak in a fluid based cooling system and purging the fluid therein under various conditions. The system, method and apparatus detect fluid levels in the cooling system, fluid pressure in the cooling system and fluid spraying and dripping from the cooling system. Upon an affirmative determination of low fluid levels, low fluid pressure or fluid spraying and dripping from one or more locations in the cooling system, the device automatically purges the fluid from the cooling system. Accordingly, in an overhead fluid-based cooling system, any damage to objects below from having fluid leaked thereon is minimized.

  • Patent number: 5495969
    Abstract: A gun rack engages the rear of the back seat of a sports vehicle and enables weapons to be carried in a manner tilting toward the front of the vehicle. The rack has no middle struts which would interfere with the scope of rifle and thus allows the rifle to be carried scope down, a much more stable configuration. The rack of the present invention is completely foldable from and to a storage position, and contains specialized structures to enable tie down. Tie-downs are made with respect to eyelets which exist in the rear of sports vehicles, and tie down is effected through the use of quick release straps. Tie down is achieved both at the upper and lower end of the rack of the present invention. Self tying is achieved through a wrap-around strap, or through a decorative over cover. The decorative over cover helps to disguise the presence of the weaponry and thus to reduce the incidence of theft.

  • Patent number: 5190281
    Abstract: The present invention is directed to a vertical stacking system comprising an apparatus and method to control stack formation based on a non-contact sensing of the reaction of the feed conveyor to the forming stack. In accordance with the invention a stream of signatures is fed by the feed conveyor onto a support surface. There is an upper feed extension of the feed conveyor located above the support surface. The stack is formed between the support surface and the feed extension. The top of the stack is adjacent to the upper feed extension. The location of the extension is determined by the location of the top of the stack. The non-contact sensing means senses the location of the feed extension and generates a location signal. This location signal is used to control a slide drive which moves the support surface.
