Abstract: A nest may have a horizontal base forming a plurality of openings and a plurality of tubular members extending downwardly from the horizontal base. Each of the tubular members may have a side wall defining a well in communication with an opening of the plurality of openings. In some embodiments, the side wall has a counterbore extending from the opening at an angle relative to a longitudinal axis of the tubular member, the counterbore having an inner surface defining a continuous circumference or perimeter. In some embodiments, the side wall has an inner surface with an upper portion defined by a series of radii of curvature providing a continuously curved surface extending from the opening and reducing a diameter of the well.

Abstract: A cabinet for a workspace definition system is provided which comprises a housing defined by a rear wall, a pair of side walls, a top wall and a bottom wall interconnected together to form an integral unit surrounding an interior chamber. One of the top wall, the rear wall and the side walls further comprises a port, and a length of electrical/data conduit extends through the port into at least one of the rear wall, the side walls, and the interior chamber of the cabinet. One of the top wall, the rear wall and the side walls can also have an electrical/data receptacle mounted therein and accessible from the outside of the cabinet. The electrical/data conduit is thereby passed into the walls and the interior chamber of the cabinet in a concealed manner to provide operability to components stored within or adjacent to the cabinet.

Abstract: An improved workspace management system for dividing a space into separate work areas comprises a rigid structural framework formed of rigid rectangular frames rigidly joined together at the edges thereof to form at least one work area. Each of the frames has outer faces on opposite sides thereof and openings on the opposite sides of the frames and a plurality of interchangeable tiles, with each of the tiles having a connector cooperating with the openings on the frames for removably mounting the tiles to the frames for ease of placement on and removal from the frames. The tiles are mounted to the outer faces of the frames to substantially cover both sides of the frames from a bottom portion thereof to a top thereof in juxtaposed parallel relationship.

Abstract: A catheter is disclosed which is capable of cutting obstructive tissue from a vessel of a living body while shielding a portion of the wall of the vessel from being exposed to the cutting blade at the catheter's distal end. An essentially continuous outer surface at the catheter's distal end allows it to be readily advanced through an introducer sheath and through a tight stenosis in an artery. The shield at the catheter's distal end could subtend an arc from as little as 45 degrees to as large as 270 degrees depending on the extent of the vessel wall that is to be protected from being cut. A vacuum source at the catheter's proximal end can cause a suction to exist at a cutout at the catheter's distal end in order to pull obstructive tissue into the cutout as the cutting cylinder is pulled back in a retrograde direction, this suction being capable of enhancing the removal of the obstructive tissue.

Abstract: A double antibody sandwich immunosorbent assay for detecting alpha-1-antitrypsin (.alpha..sub.1 AT) comprising the steps of: (1) reacting (a) a first-species-of-animal antibody to .alpha..sub.1 AT with (b) a solid substrate; (2) reacting (a) .alpha..sub.1 AT in a sample suspected of containing .alpha..sub.1 AT with (b) the first-species-of animal polyclonal antibody to .alpha..sub.1 AT; (3) reacting (a) a second-species-of-animal antibody to .alpha..sub.1 AT with (b) the .alpha..sub.1 AT in a sample suspected of containing .alpha..sub.1 AT; (4) reacting (a) a labelled antibody comprising a first-species-of-animal antibody to an antibody from a second species of animal with (b) the second-species-of-animal antibody to .alpha..sub.1 AT; and (5) detecting the amount of labelled first-species-of-animal antibody to antibody from the second species of animal that reacted with the second-species-of-animal polyclonal antibody to .alpha..sub.

Abstract: An artificial structure for attracting fish, which structure includes a ballast and anchoring subassembly having an elongated trunk detachably and pivotally connected thereto and extending in a generally vertical direction therefrom. A plurality of elongated leaf fronds are each centrally engaged with the trunk at longitudinally spaced intervals along the trunk.
