Abstract: A frame assembly for a canoe backpack carrier comprising of a support rods and cross braces, adjustable webbing and straps, which allows for an individual to carry a canoe of substantial weight over rough terrain.

Abstract: A foamed polyethylene product has an outer sheath of non-foamed polyethylene fused to an underlying foamed body portion. Preferably, the product is produced in an in-line method when the foam body is extruded and subsequently the skin is extruded directly on the body portion. This process only causes limited thermal degradation of an outer layer of the body portion which improves adhesion of the skin to the body portion.

Abstract: A biopsy forceps device encompassing integrally designed parts for opening and closing the cutting jaws of the device and reducing the number of individual parts in the entire device and having features which specifically reduce the number of parts involved in the pivot mechanism, and having features which eliminate projections which may damage equipment used in conjunction with the device, and having features which specifically permit the device to obtain and store more than one tissue sample.

Abstract: A closure system comprised of a passive surface, an engageable surface and an adhesive surface that may be applied to a number or surfaces such as paper and plastic.

Abstract: An extruder for forming elongated articles made of a thermoplastic having a cross-section that varies along their length comprising a moveable means for defining an extrusion orifice.

Abstract: A lift for a vehicle comprising a displaceable support device moveable between a first inground position to a second above ground position for supporting the vehicle, scissor mechanism associated with the displaceable support device for lifting the displaceable support structure and the vehicle, support frame member disposed inground, the scissor mechanism contained in the support frame member where the displaceable support device moves between the first and second positions.

Abstract: The invention relates to methods of forming sintered compacts of low alloy steel composition to high density at ambient temperature. The invention provides for a method of forming sintered powder metal articles by forming the sintered powder metal in a die cavity having a clearance for movement of said sintered powder metal to a final shape with increased density after compaction wherein the formed sintered powder metal article has a compaction length which is approximately 3 to 30% less than the original length.

Abstract: A fluid dispensing device for dispensing fluid on overhead plants comprising a container and plunger. A process for dispensing fluid onto overhead plants using a fluid dispensing device comprising a container and plunger.

Abstract: An entrance device having at least two barriers to permit entrance in one direction comprising a first barrier manually displaceable from a closed position to an open position and a second barrier manually displaceable from a closed position to an open position when said first barrier is being engaged to achieve said second open position wherein said first and second barriers are presented by said entrance device in sequence.

Abstract: A collapsible fishing net device comprising a handle having a first end and second end, and fastening block disposed within said handle and adjacent to said first end; collapsible net frame comprising a hinge means comprising a first hinge arm, and second hinge arm first net frame arm and second net frame arm associated with said first and second hinge arms respectively wherein each of said first and second net frame arms presents a first end which is proximal to said hinge means and second end which is distal to said hinge means; coupler adjacent to said distal end of said first and second net frame arms, said coupler being engageable to couple said first and second net frame arms, fastener operably associated with said hinge means and fastening block to fasten said collapsible net frame to said handle assembly; and net associated with said collapsible net frame wherein said fastening block receives said fastener and said first and second net frame arms are coupled by said coupling means to present a substan

Abstract: An aircraft instrument system that informs the pilot of whether, during the takeoff roll, the aircraft's acceleration rate is sufficient to ensure that V1 speed will be achieved at the expected time (and thus distance), and, if not, how far in distance the aircraft is lagging behind the required acceleration schedule.
