Publication number: 20030234469Abstract: An apparatus for forming a tube construct from a planar sheet matrix includes a stand supporting two opposing mounts and spanning between the opposing mounts are a mandrel, a porous rod, and a spring-loaded roller held in parallel arrangement; a guide for aligning and engaging the mandrel on the opposing mounts; and a means for imparting a tangential force on the planar sheet matrix to prevent wrinkling. The porous rod has a lumen running its length and has pores that communicate between the lumen of the porous rod through to the surface of the rod for water to uniformly pass through. The spring-loaded roller runs along the length of the porous rod creating a line of contact between the roller and the mandrel. The mandrel is contacted with a planar sheet of matrix and is rotated such that successive portions of the matrix contact the porous rod and become lightly moistened by the water passing through the pores of the porous rod and become wrapped around the mandrel to form a tube construct.Type: ApplicationFiled: December 19, 2002Publication date: December 25, 2003Applicant: Organogenesis, Inc.Inventors: Maury D. Cosman, Kristen Billiar, Ryan Mercer, Bruce Miller

Patent number: 6640587Abstract: A mold for shaping end portions of glass tubes has first and second mating members which define a contoured bore into which the heated tube fits. Each member has a longitudinal bore from which extend radial bores opening into the interior cavity of the mold containing the tube. Each member also has radial vent bores for venting gases and vapor to the outside. Each longitudinal bore is connected to a lubricant, such as water, supply, which is applied to the surface of the tube through the radial bores.Type: GrantFiled: September 29, 2000Date of Patent: November 4, 2003Assignee: Lucent Technologies Inc.Inventors: David B. Hollesen, Peter M. Mueller, Gerald P. Nunnally, Ivan Pawlenko, Larry Samson

Patent number: 6589042Abstract: An apparatus for shaping thermoplastic materials or for laminating backing parts includes a turntable driven by a rotary drive and having rests for receiving supporting devices for lower molds or backing parts. The turntable has a plurality of receiving places which can enter alternately into a preliminary blowing box, where a molded part can be shaped in conjunction with an upper mold arranged on an upper table. The preliminary blowing box has a front wall with an opening, facing the rotary drive. The turntable has a separating wall with flanges on both side which engage a wall indentation which surrounds the rotary drive and consequently bounds the preliminary blowing box, in order to seal the opening. A seal which can be shaped by means f a pressure medium and can be pressed against the separating wall is located in the front wall of the preliminary blowing box about the opening.Type: GrantFiled: February 28, 2001Date of Patent: July 8, 2003Assignee: Paul Kiefel GmbHInventors: Gernold Stämmler, Kurt Rosenmayer, Reiner Huber

Patent number: 6540501Abstract: A method for creating decorative patterns on surfaces of cured concrete blocks includes a plurality of texturing elements secured to one or more rotatable shaft via a plurality of flexible support cables. Upon rotation of the shaft, centrifugal force causes the secured texturing elements to radially extend from the shaft. The blocks are preferably positioned such that the rotating texturing elements repeatedly come into contact with particular surfaces of the blocks, thereby forming a textured or antiqued pattern on such block surfaces. In a particular embodiment, the rotatable shaft is reciprocally moved in a direction parallel to the block surfaces to be patterned, whereby an entire block surface is exposed to the rotating texturing elements.Type: GrantFiled: November 21, 2000Date of Patent: April 1, 2003Assignee: Allan Block CorporationInventor: Timothy Allen Bott

Patent number: 6419475Abstract: A method for treating a roller cover includes the steps of positioning an element with respect to a roller cover and removing a portion of the roller cover with the element to form a pattern on the roller cover. The process for treating roller covers for a paint roller may also include the steps of providing a surface, forming a pattern on the surface, heating the surface, and contacting the roller cover with the heated surface. The heated surface is a metal. The heat is transferred from the heated metal surface to the roller cover when the heated metal surface contacts the roller cover. The heated surface sears or melts the nap of the roller cover. The surface can be provided with a pattern so that a pattern can be placed into the nap of the roller cover. An apparatus used to treat the surface of a roller cover includes a surface having a desired pattern therein. A holder for a roller cover holds or presents the roller cover to the surface. A heater is attached to the surface.Type: GrantFiled: October 1, 1999Date of Patent: July 16, 2002Assignee: Wagner Spray Tech CorporationInventors: George H. Wakat, Alan Neumann

Patent number: 6394783Abstract: An apparatus for thermoforming a thermoplastic article comprises an extrusion die for extruding a sheet of thermoplastic and a rotating wheel having at least one mold member. The mold member includes a male mold or forming cavity for receiving at least a portion of a substantially non-oriented (i.e., non-tensioned) thermoplastic sheet. The mold member is selectively heated and/or cooled during thermoforming to maintain the sheet in a molten or thermoformable state. The mold member also comprises a stripper plate maintained at a predetermined temperature or temperature distribution for inducing a predetermined degree of crystallinity to the sheet. The stripper plate enables the articles to be separated from the mold without distortion. In one embodiment, the thermoformed article has at least two and preferably at least three distinct regions of thermally-induced crystallinity.Type: GrantFiled: March 27, 2000Date of Patent: May 28, 2002Assignee: Apex Research Ltd., Inc.Inventors: Edward J.

Patent number: 6250908Abstract: An apparatus is disclosed for making a conduit or pipe. An extruder is provided for producing a strip of continuous thermoplastic. A winding drum receives the strip and helically winds the strip around the drum's perimeter to form a conduit having an inner diameter corresponding to the outer diameter of the drum. The drum includes a core tube surrounded by a plurality of rollers which define the outer diameter of the drum. The rollers rotate to advance the strip around the drum. A plurality of support columns are used to support the roller at each end. A hub assembly is used to movably support the support columns in slidable engagement. The support columns are radially displaced by the hub assembly between two positions, in order to vary the outer diameter of the drum between two diameters.Type: GrantFiled: February 23, 1999Date of Patent: June 26, 2001Assignee: The Lamson & Sessions Co.Inventor: George J.
