Patent number: 8287787Abstract: The present invention generally relates to a cooling process and system that can be utilized in the manufacture of flexible elongate extruded materials, such as tubing or jacketed electrical wire and cable. More particularly, the present invention relates to a cooling trough for cooling flexible elongate extruded materials after extrusion. Cooling trough embodiments have a base, a wet cooling chamber above the base, and an air dry chamber above the wet cooling chamber. The base contains a reservoir for collecting and storing a cooling liquid. An extruded material, such as a cable, enters the wet cooling chamber, where the cooling liquid from the reservoir is sprayed onto the material, the material is then passed to the air dry chamber where it is dried.Type: GrantFiled: July 27, 2011Date of Patent: October 16, 2012Assignee: Cerro Wire LLCInventor: Douglas P. Henderson

Patent number: 6939709Abstract: A multi-well plate assembly has a well plate with a plurality of closed-bottom, open-top wells of substantially uniform square cross-section between the closed bottom and the open top. An insert plate is nested with the well plate and has a top wall substantially covering the open tops of the wells. Inserts project down from the top wall and into the respective wells, such that each insert is nested in a corner of the well. Access ports are formed through the insert plate for alignment with a corner of the respective well opposite the insert. The access port is formed partly through the top wall of the insert plate and partly through the sidewall of the insert.Type: GrantFiled: August 26, 2003Date of Patent: September 6, 2005Assignee: Becton, Dickinson and CompanyInventors: Douglas P. Henderson, Alan Trieber

Patent number: 5801055Abstract: A multi-well culture dish assembly is provided which includes an insert having rows of frustoconical enclosures and a well plate in which the enclosures are suspended. The insert includes a top wall having a peripheral flange, the enclosures being integral with and extending downwardly from the top wall. Each enclosure includes a radial opening which extends into the upper portion of the enclosure. Rows of openings are formed in the top wall of the insert, and respectively adjoin the radial openings in the enclosures. The relatively large pipette openings are formed by the adjoining openings. The well plate may include rows of cylindrical wells. The enclosures are positioned within the wells and are radially offset with respect thereto. The openings within the top wall of the insert are in registration with the wells when the insert is mounted to the well plate.Type: GrantFiled: September 10, 1997Date of Patent: September 1, 1998Assignee: Becton Dickinson and CompanyInventor: Douglas P.

Patent number: 5285907Abstract: This invention involves racks or tray arrays for use in clinical laboratories, in particular, to support tubes and other containers holding body fluid specimens. The invention allows the user to "build" racks or arrays of larger and/or smaller capacity, depending upon the user's requirements, by rapid snapping together of a plurality of identical modular tube units. The racks or units may have a variety of size openings for accommodating different size specimen containers, and containers of different configuration. Thus, the user can maintain stable support of a great many containers simultaneously for handling in the laboratory, thus avoiding the danger of dropping or spilling specimens. The arrangements of the invention may be comprised of reusable, autoclavable moldable plastic materials, or less expensive throw away moldable materials. The individual components making up the tube rack array may be of a variety of geometric configurations.Type: GrantFiled: May 14, 1992Date of Patent: February 15, 1994Assignee: Becton, Dickinson and CompanyInventors: Larry A. Franchere, Douglas P. Henderson
