Publication number: 20090178361Abstract: Thermoplastic materials are now extruded with the final, desired cross sectional profiles and often have protective surfaces of a polyvinylchloride shell co-extruded on one or more than one of their outer surfaces. These profiles typically have hollow axial channels or cores running the length of the extrusion which applicant has found can be used to increase the rigidity of such profiles by inserting reinforcing members into such axial channels and fixedly securing the reinforcing member to the profile by mechanical fastening means and thereafter using such profiles to construct rectangular frames for windows, doors, casement and the like. The technique allows such reinforced profiles to be employed in frames where the mechanical loadings on such frames would otherwise prevent the use of such extruded profiles.Type: ApplicationFiled: December 5, 2007Publication date: July 16, 2009Inventor: Kuei Yung Chen

Each of the layers may enhance one or more of the desired guide wire characteristics, with the combination of layers providing the desired combination of guide wire characteristics. Each of the layers may be provided over the entire guide wire, or only over selected portions of the guide wire. Further, selected layers may be co-extruded over the guide wire, which may reduce the manufacturing costs associated therewith.Type: GrantFiled: March 13, 1998Date of Patent: January 22, 2002Assignee: Scimed Life Systems, Inc.Inventors: Jon A. Meyer, Maura Rooney, Richard J. Quigley, Thomas F. Mirarchi

Patent number: 6287406Abstract: Methods for preparing a panel unit having a panel and a frame in which a first molding piece is formed by engaging an extrusion port of an extrusion molding die with a peripheral edge of the panel and extruding an extruded molding material along the peripheral edge of the panel. The extruded molding material preferably simultaneously bonds to the peripheral edge. Waste pieces may be eliminated from the first molding piece after bonding the first molding piece to the peripheral edge and the frame may be completed by adding an additional molding piece to provide a continuously formed frame around the peripheral edge. The first molding piece may be formed by continuously moving the peripheral edge relative to the extrusion port in a predetermined orbital path. The peripheral edge of the panel may be subjected to a primer treatment before engaging the extrusion port.Type: GrantFiled: January 14, 1999Date of Patent: September 11, 2001Assignee: Tokai Kogyo Kabushiki KaishaInventors: Toshikazu Ito, Yoshihiro Suita

Patent number: 6280554Abstract: The method consists of introducing the dripper units (1) one after the other inside a conduit (2) while the latter is being formed in an extruder (10), then calibrated in a calibrator (13), heat welding the dripper units (1) to the inner wall (3) of the conduit (2) gradually as it progresses downstream of the extruder (10), then cooling the conduit (2) and perforating it opposite each dripper unit (1) to make it communicate with the exterior. According to the invention, the heat welding operation is executed downstream of the calibrator (13) by pinching the dripper unit and the wall of said conduit between first and second opposing surfaces (20, 22b) one of which is driven at the speed of progression of the conduit (2) and the other is arranged on a fixed support member (16) forming a feed guide for the dripper units (1). The dripper units are presented for the pinching operation one after the other contiguously by their ends.Type: GrantFiled: June 30, 1999Date of Patent: August 28, 2001Assignee: Swisscab S.A.Inventors: Gilles Lambert, Bruno Buluschek

Patent number: 6273977Abstract: A method for making cable of at least two thermoplastic insulated electrical conductors by thermal bonding. Two electrical conductors are moved into an extruder and are coated independently with heated thermoplastic insulation which maintains concentricity of each conductor with respect to the surrounding insulation. The insulated conductors are held in a spaced relationship until the insulation sets and then the heated insulated conductors are touched together causing the heated insulation to fuse together thereby joining them.Type: GrantFiled: April 13, 1995Date of Patent: August 14, 2001Assignee: Cable Design Technologies, Inc.Inventors: Scott W. Harden, David R. Harden

Patent number: 6248199Abstract: Cards, labels and the like containing embedded microcircuits or other elements are fabricated in a continuous process by introducing microcircuits between ribbons of extruded material, pressing the ribbons into adhesion with each other while in a plastic state thereby to make a continuous composite sheet containing the microcircuits, cooling the composite sheet to solidify the extrudate material, and cutting out cards from the composite sheet, each card containing a microcircuit. The microcircuits may be introduced between the extruded ribbons on a continuous carrier sheet which may also serve as a printed circuit substrate for the microcircuits. Alternatively, the microcircuits are inserted as discrete units between the extruded ribbons by a suitable robotic device.Type: GrantFiled: April 26, 1999Date of Patent: June 19, 2001Assignee: Soundcraft, Inc.Inventor: Joel R.
