Abstract: A liquid sampler for use in sampling the liquid in a well. The sampler has a tube for containing the sample and an inlet at the bottom and an outlet at the top. An inlet check valve is located at the inlet which has a door configured autonomously to move between open and closed configurations in response to fluid flow through the inlet. In the open configuration, the door is aligned with the axis of the tube to allow fluid to flow into the tube through the inlet from below, and in the closed configuration, the door is positioned transverse to the axis of the tube to block fluid flow from the tube out through the inlet thereby retaining fluid within the tube as the sampler is raised up.

Abstract: The present invention provides compositions and methods for increasing the efficiency of phage display. A first aspect of the present invention is a bacterial strain that stably comprises at least one gene that encodes a protein having a packaging function for a filamentous phage. A bacterial strain of the present invention can be transformed with a phage display expression construct that comprises a coat protein fusion protein or coat protein chimeric protein and used to generate packaged recombinant phage particles in the absence of a helper phage. In some preferred aspects of the invention, the bacterial strain contains ten of the eleven genes of an Ff filamentous phage that encode packaging functions, where a filamentous phage gene not contained by the bacterial strain is a coat protein gene that is provided on a phage display expression construct for the generation of fusion coat proteins or chimeric coat proteins.

Abstract: A novel cut pile fabric (10) and a method of making same is disclosed. The cut pile fabric (10) includes a needled non-woven batt (14) of staple fibers (12) that is processed on a texturizing needle loom (17) from one surface (20) (called a back surface) thereof to form texturized loops (18) on the other surface (22) (called a face surface) of said batt (14). The non-textured back surface (20) of the batt (14) has a backing (24) applied thereto which may be of latex, or the like, with the texturized loops (18) being tigered by a tigering roll (28) to cut, break or fracture a high percentage of the loops. The tigered pile is polished by a polishing roll (34) to remove the crimps in the fibers and to orient the fibers in a direction transverse to the batt (14) prior to being sheared in a shear (36). A dense, plush cut pile fabric is produced.

Abstract: A novel cut pile fabric (210) and a method of making same is disclosed. The cut pile fabric (210) includes a needled non-woven batt (14) of staple fibers (12) that has an integral carrier member (74) formed by fusing a face surface (22) of the needled batt. A texturized surface is formed on the batt (14) using a texturized needle loom (17) which punches through the batt (14) from the one surface (20) (called the back surface) of the batt so that texturized loops (76) project from the carrier member (74). The non-texturized back surface (20) of the batt (14) has a backing (24) applied as by latexing, fusing, or the like, with the texturized loops (76) being tigered by a tigering roll (28) to break, fracture or cut a high percentage of the loops (76). The tigered pile is polished by a polishing roll (34) to remove the crimps in the fibers and to orient the fibers in a direction transverse to the plane of the batt (14) prior to being sheared in a shear (36).
