Abstract: The present invention is an improved mechanical linear locking device, with a single locking coiled spring. When firmly coiled, the single locking coil spring is able to grip a smooth rod and prevent axial motion. When the single locking coil spring is uncoiled, slightly, it releases its grip on the smooth rod, allowing axial motion. The single spring linear adjusting lock device is used in an armrest with memory. The present invention uses a rod, a return spring, an annular bearing, a sleeve, a two-piece housing, a coil spring, a bushing, and a cylinder with protruding trunnions.

Abstract: A sealing system for a pump having a plunger includes a housing having an internal chamber adapted to receive a portion of the plunger. Primary and secondary seals are located within the internal chamber and adapted to sealingly engage the plunger. The primary seal communicates with the fluid being pumped. A barrier fluid chamber contains a barrier fluid in contact with the primary seal and the secondary seal. A pressure referencing device has an inlet port in communication with the pumped fluid and an outlet port providing fluid at a pressure magnitude equal to a peak pressure of the pumped fluid. A pressurizing device is in communication with the fluid at the peak pressure and the barrier fluid to maintain the barrier fluid pressure at a magnitude greater than the peak pressure of the pumped fluid such that the pumped fluid is restricted from leaking past the primary seal.

Abstract: A sealing system for a pump includes a housing having an internal chamber adapted to receive a portion of a plunger. A primary seal is translatable within the chamber in sealing relation with the housing. The primary seal includes first and second elastomeric members adapted to sealingly engage the plunger. The first and second elastomeric members are spaced apart from one another a distance greater than or equal to a maximum stroke of the plunger. A secondary seal is spaced apart from the primary seal and adapted to sealingly engage the plunger. A chamber contains a barrier fluid in contact with the primary seal and the secondary seal. A pressurizing device maintains a pressure of barrier fluid at a magnitude greater than a peak pressure of a fluid pumped by the plunger such that the pumped fluid is restricted from entering the barrier fluid chamber.

Abstract: Disclosed is a dynamic winged animal device which includes a body and a lift member which defines a right wing and a left wing. The wings further include a fixed curvature over at the leading edge of the wings to provide airfoil characteristics and movement of the wings of the particular animal being portrayed. A spar or support is attached to the outer portions of the wings and provides a flexible support base for the natural movement of the wings in the air. The distance between the center portion of the wing span and the spar may vary during flight.

Abstract: A decoy is described in which a base is formed as a silhouette of at least one animal. A preferred form includes an image of one animal visually identifiable on the base and part of at least a second animal on the same base, thereby creating a visual image of at least two animals. In one preferred form, the sheet includes opposed liners separated by internal flutes forming elongated chambers extending at least partially across the sheet. A seal closes ends of a number of the elongated chambers renders the base buoyant in water. A support member is shaped to be frictionally received within one of the elongated chambers to extend from the base to a remote end. In a preferred form, a ballast member is mounted at the remote end of the support member.

Abstract: A one person hunting blind is described in which an elongated rigid substantially water tight shell includes a bottom wall, longitudinal side walls, bow and stern end walls joining the side walls, and a top deck wall. The walls define an open occupant receiving compartment. The top deck wall includes an opening extending from the stern end toward the bow end, openly communicating with the occupant receiving compartment. The walls are shaped to receive a single occupant in a supine position with the occupant's legs and feet being covered by the top deck wall. In a preferred form, a wheel mounting member is provided on the shell between the bow and stern end walls and at least one wheel is removably mounted to the wheel mounting member and engageable with a ground surface to facilitate moving the shell over the ground surface. Floats are provided in a preferred form of the blind.

Abstract: A water craft with a removable duck blind cabin house assembly is described. A circumferential gunwale defines an open passenger compartment with a sole deck surface below and inboard of the gunwale. A duck blind cabin house structure is removably attached to the hull along the perimeter of the gunwale to selectively enclose the passenger compartment. A duck blind camouflage receiver is provided on the cabin house structure for releasably mounting camouflage materials about the craft. Mounting members on the hull and cabin house structure (a) secure the cabin house structure to the hull in a first condition at least partially covering the hull and forming the passenger compartment so the water craft may be utilized as a duck blind, and (b) release the cabin house structure for removal from the hull for use as an open boat.

Abstract: A decoy is described using a photographic decoy image on at least one surface of a relatively flat decoy body. The photographic image includes a low glare coating to minimize reflection. The body is preferably formed of a weatherproof plastic material. The preferred material is polyethylene and an alternate material is ABS plastic. Either the preferred or alternate material may be co-extruded with a darkened core layer of recycled, reground material and light colored surface areas of virgin material. The surfaces are treated, preferably by a corona discharge treating system, to produce a printable surface area. A four color printing process is used to transfer the photographic images of the animals onto the treated surface. Ultraviolet inks are used for this purpose. A fifth coat of transparent ultraviolet ink mixed with fine silica is used to produce an extremely low reflective surface on the image. A stake is fitted through appropriate stake receiving apertures for upright forms of the present decoy body.
