Abstract: A camouflage cover for equipping an outdoor enclosure with three-dimensional nature effects includes a plurality of elongated nature-effect strands that drape over the enclosure in a substantially vertical arrangement. The vine-like nature-effect strands help conceal hard lines and corners of the enclosure structure. The cover may include adjustment straps that allow a single cover to adapt to a number of enclosure structures. The adjustment straps, where used, may include interwoven cords and cord locks for adjusting tension of the straps. The nature-effect strands may have different camouflage patterns so that an enclosure can have an appropriate camouflage scheme no matter what season or environment. Tiebacks may optionally be used to permit horizontal adjustment of the nature-effect strands, in order to prevent allow free access to windows and doorways. Auxiliary loops may also be provided to allow attachment of additional nature effects by a user.

Abstract: A reinforced archery arrow shaft includes a tubular core, with an attached two-part sleeve either covering the core, or disposed inside the core as a liner. The core may include carbon therein. The sleeve includes at least one higher-density front section formed from a fabric material, which is wrapped around and affixed to the core. The sleeve also includes a lower-density rear section wrapped around and affixed to the core behind the front section. The sleeve fabric may have a decorative design or pattern on the exterior surface thereof. The higher density of the front section provides front-of-center weight distribution in the finished arrow shaft. Optionally, accessories may be attached to the arrow shaft to form an arrow.

Abstract: A collapsible and portable enclosure, for providing covering concealment to a user, includes one or more flexible plastic window panels which function as one-way mirrors during daylight hours. The enclosure includes a fabric cover having at least one side wall, and a support structure for supporting the fabric cover. The support structure may include a plurality of collapsible hub-and-strut assemblies. The fabric cover has at least one window opening formed through the side wall, and a flexible panel extending across the window opening. The flexible panel has a partially reflective exterior surface which partially reflects light and partially transmits light, allowing the flexible panel to effectively function as a one-way mirror. Optionally, the flexible panel may be removable and replaceable, allowing a hunter to shoot through the panel and to replace it later.

Abstract: Scent-suppressing fiber to be woven into articles of clothing or other equipment formed of fabric to inhibit or eliminate the emission of scents when the wearer is in the vicinity of wildlife. The fiber is a conventional thread coated with carbon. A fabric sheet is formed completely of woven carbon scent-suppressing fibers, or alternatively may be formed of carbon scent-suppressing fibers interwoven with conventional fibers. The resulting fabric sheet is formed into articles of clothing to suppress scent emission that highly sensitive wild creatures can detect. Because the fiber is structurally a part of the clothing article, its cost is less than if the scent-suppressing fiber were applied superficially, as in a sandwich type layering system. Also, because the fiber is continuously present in the material, the scent-suppressing capability covers the entire garment and is not limited only to large surface areas.

Abstract: In a method of making an arrow shaft, a fabric section is placed around a hollow tubular core, and is affixed thereto. The core may include carbon therein. An adhesive or protective composition, associated with the fabric, is cured to adhere the fabric to the core. The adhesive may be impregnated into the fabric prior to its placement on the core, or may be applied to the fabric by methods such as spraying, dipping, brushing, or powder coating. The shaft may be treated to make the exterior surface smooth after curing. A reinforced archery arrow shaft made by the method includes a tubular core and an attached fabric sleeve covering the core. The fabric is wrapped around and affixed to the core. The sleeve fabric may have a decorative design or pattern on the exterior surface thereof. Optionally, accessories may be attached to the arrow shaft to form an arrow.

Abstract: A method of applying a decorative undercoat and a sound-dampening elastomeric outer coating onto a workpiece may be used on a workpiece that is expected to movably contact another adjacent component when used as part of an assembly. The workpiece may be roughened through sanding by machine or by hand, and then may be sprayed with a base paint coat. The workpiece is then placed in a baking chamber where the base coat is allowed to partially cure so that a subsequent coating will adhere thereto. The workpiece is then coated with an image bearing film, and is then again heated to cure the decorative image-bearing film. Then, the workpiece is sprayed with an elastomeric coating over the dried decorative film and allowed to final cure in a baking chamber.

Abstract: A portable hunting blind or enclosure, to provide cover to a hunter or naturalist in the field, is provided with a scent-dampening liner. An enclosure according to one embodiment includes at least one wall, and a lining material disposed on a surface thereof. In the described embodiment, the lining material includes a binder and a multiplicity of carbon particles interspersed in the binder. The liner may be directly affixed to an inner wall surface. Alternatively, the lining material may be affixed to a separate fabric surface, which is attached to the inner wall. In another aspect, the enclosure includes screen panel sections pivotally connected in a sequence. In still another aspect, a tent-like structure is formed of flexible fabric and includes a roof section and a support structure.

Abstract: A food marinating apparatus includes a substantially cylindrical canister and a base unit including a motor, a plurality of rollers, a vacuum pump, and a control panel. The base unit is operable to rotate the canister thereon. The vacuum pump is provided for reducing the ambient pressure inside of the vessel, to improve marinade absorption by the food. Food such as meat or fish will receive marinade more quickly under low pressure than under atmospheric pressure, and additionally, by rotating the containment vessel, the food is agitated in the presence of the marinade, for a higher degree of marinade absorption.

Abstract: A wild game feeding apparatus includes a support structure, a food distributor, and a collapsible reservoir. The reservoir is made collapsible in order to minimize the size of the apparatus for ease of storage and transport. Wild game feed, such as corn, wheat, or other particulate food is loaded into the collapsible container, whence it exits out of the bottom of the container and contacts the distributor. The distributor includes a rotating plate for distributing the food in a limited radius from the feeder apparatus. Optionally, the apparatus may include a control mechanism including a timer, to actuate operation thereof at specific time intervals which are pre-set by a user.

Abstract: A stove for outdoor use includes a hollow shell formed from heat-tolerant material, and a substructure for supporting the shell. The stove also includes a burner assembly, operatively attached to the shell or to the substructure, and a vessel support rack for placement on the shell. The support rack is formed from multiple interconnected segments.

Abstract: An outdoor heating apparatus, for warming the ambient air of a pre-selected area, includes a movable table attachment. The height-adjustable tabletop ergonomically enhances the surrounding area to accommodate the needs of various users, and an optional sectional heat transfer dome lowers shipping and packaging costs and reduces storage space. While the heating apparatus operates in a manner similar to that of traditional outdoor heaters, a fillable reservoir in the base member provides additional stability after the apparatus is assembled.
