Patent number: 6007656Abstract: In the manufacture of a structural member comprising a thermoplastic composite core with an exterior reinforcing layer, the core member is initially extruded in the shape of a profile. The profile is then contacted with reinforcing fiber and resin to form the exterior reinforcing layer. The exterior thermosetting layer is cured to form a reinforcing layer. The structural member is preferably manufactured using a pultrusion method in which a tractor device is used to provide linear movement of the profile from the extrusion head to the exterior coating operation. The fiber-reinforced thermoset is coated on the entirety of the exterior of the profile or is applied only on a portion of the profile requiring reinforcement in a defined load-bearing direction. The preferred thermoplastic core comprises a polymer-fiber composite material.Type: GrantFiled: July 26, 1996Date of Patent: December 28, 1999Assignee: Andersen CorporationInventors: Kurt E.

Patent number: 5976649Abstract: An improved method is disclosed for the fusing, joining or seaming of cellulosic materials. The method utilizes a hydroxide solution of selected organometallic compounds or metal oxides to rapidly crosslink opposing, overlapping cellulosic surfaces to provide secure seams. In particular, the invention is directed to the production, either on-line or off-line, of tubular cellulosic casings for the manufacture of sausages and sausage-like products. The seams according to this invention have such high shear strength that extremely narrow bond widths are possible. The narrowness of the bond site eliminates or minimizes striping or discoloration of the finished product.Type: GrantFiled: September 23, 1997Date of Patent: November 2, 1999Assignee: Kraft Foods, Inc.Inventors: David F.

Patent number: 5976285Abstract: A method of manufacturing a downhole electrical cable is described. The method comprises arranging an elongate member adjacent to a flat elongate sheet of material, where the length of the elongate member is greater than the length of the flat elongate sheet. The elongate sheet is then formed into a cylindrical shape around the elongate member, and the adjacent longitudinal edges of the cylindrical shape are joined, preferably by seam welding, to form the elongate sheet into a tube with an end of the elongate member adjacent each end of the -tube. Thereafter, an elongate conductor is connected to one end of the elongate member, and the other end of the elongate member is pulled to draw the elongate conductor through the tube until the elongate member is removed from the tube and the elongate conductor is located within the tube. At this final point in the method, an end of the elongate conductor is adjacent each end of the tube.Type: GrantFiled: November 25, 1997Date of Patent: November 2, 1999Assignee: Wood Group Production Technology LimitedInventor: Peter Martin McKee
