Patent number: 6547908Abstract: A method is shown for manufacturing a polyethylene jacket of the type used in pre-insulated piping systems. A mandrel is first coated with a brittle polymeric coating. A melt profile of polyethylene is then extruded onto the mandrel and spirally wound to produce adjacent windings. The adjacent windings make contact to form a finished jacket which is in engagement with the brittle coating. After the jacket has set, an external compressive force is applied to the tubular member thus formed sufficient to crush the internal brittle coating, thereby freeing the polyethylene jacket from engagement with the mandrel. The jacket can then be removed from the mandrel.Type: GrantFiled: July 30, 2001Date of Patent: April 15, 2003Assignee: Thermacor Process, Inc.Inventors: Thomas Joseph Keyes, James Bass

Patent number: 5792323Abstract: A belt for use on a long nip press for dewatering a fibrous web includes a base assembled by spirally winding a prepared structure strip in a plurality of non-overlapping turns. Successive turns are abutted against and joined to those previously wound by sewing or otherwise bonding along the continuous spiral seam thus formed. The prepared structure strip may be a fabric strip woven from lengthwise and crosswise yarns, which may be monofilament yarns of a synthetic polymeric resin. The fabric strip may be of either a single- or multi-layer weave. At least one side of the base, namely, that side which will be on the inside of the belt in its endless loop form, and which slides over the arcuate pressure shoe component of the long nip press during its operation, is coated with a polymeric resin, such as polyurethane, to render it impervious to liquids, and especially to the oil used to lubricate the surface of the arcuate pressure shoe.Type: GrantFiled: September 7, 1995Date of Patent: August 11, 1998Assignee: Albany International Corp.Inventor: Erik Wilhelm Grondahl

Patent number: 5792296Abstract: An apparatus and method provide for the alternate manufacture of permanent adhesive or repositional linerless labels utilizing the same equipment. Indicia is applied such as by using a flexographic unit in which the print cylinders are immediately thrown-off the web when the unit is turned off. Coating stations apply a repositional adhesive and release coat in the construction of repositional adhesive labels, for example, using a flexo unit in which the print cylinder stays in contact with the web after the unit is turned off to wipe excess adhesive from the print cylinder. In the construction of permanent adhesive labels a coating station for applying a release coat and a release coat curing station, as well as a hot melt permanent adhesive application station, are also provided. The permanent adhesive is applied with a slotted die head having a heat uniformity of +/- five degrees F. across its length, and applies an even adhesive coat thickness of about 0.0005-0.001 inches to +/- about 0.0001 inches.Type: GrantFiled: December 31, 1996Date of Patent: August 11, 1998Assignee: Moore Business Forms, Inc.Inventor: John R.

Patent number: 5788586Abstract: A golf club having a vibration damping device including a club head, a shaft connected to the club head having resonant frequencies over a predetermined range and a rod disposed within the shaft with a viscoelastic material interposed between the shaft and the rod. The rod is flexible and has resonant frequencies over the same frequency range as the shaft such that the shaft and rod vibrate out of phase with respect to each other and thereby deform the viscoelastic material to damp vibrations in the shaft.Type: GrantFiled: January 30, 1997Date of Patent: August 4, 1998Assignee: Roush Anatrol, Inc.Inventor: Paul J. Macioce

Patent number: 5773108Abstract: A containment structure for radially deployable devices in the form of a self-coiling composite band. The composite band is fabricated as a lay up of epoxy resin-impregnated ply layers of cloth material that are wrapped about a mandrel and cured in a specific ordered sequence. The ordered sequence of fabrication steps of applying and curing the resin-impregnated cloth layers to the mandrel provides a desired separation of the cured ply layers of the final composite so that they are located at the outer most regions of the composite and are separated by an intermediate resin layer of desired thickness. This ensures a composite band which is effective to function as a negator-spring or composite clock spring and which also exhibits a good combination of mechanical properties, such as elastic modulus, strength, and resilience. In use, the self-coiling composite band is applied about the periphery of a central hub of a radially deployable device by wrapping it therearound in a reverse curl orientation.Type: GrantFiled: June 14, 1996Date of Patent: June 30, 1998Assignee: Lockheed Martin CorporationInventor: Matthew Casebolt

Patent number: 5755905Abstract: The method of the present invention provides a way to make rolls of high shear strength pressure sensitive adhesive tapes with a transparent to the core appearance in a relatively short time and without the need to subject the rolls to additional method steps. Moreover, the present invention achieves such transparent to the core appearance by sufficiently wetting-out the adhesive on the tape backing to remove microscopic air bubbles entrapped within the harder and less deformable high shear strength adhesive layers. The method comprises a rewinding method and is characterized by the use of a pack roll during rewinding to provide a sufficiently high contact pressure to the non-adhesive side of the tape substantially at the application point of the tape to the tape roll. In one aspect, a sufficient contact pressure is provided by the pack roll so that the pressure sensitive adhesive tape rolls are made with a transparent to the core appearance at the time of the rewinding step.Type: GrantFiled: July 25, 1997Date of Patent: May 26, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: Michael J.

Patent number: 5749985Abstract: Process for optimizing the features of multilayered tubes made of fibrous composite materials, allowing to maintain within the specified limits the limit elongations and stresses which they withstand in response to the applied strains. The process comprises selecting at least two optimized features characteristic of each layer (its thickness and the winding angle of the fibers for example) by starting from an initial tube selected a priori. Through small deviations applied to the parameters, the relations between small deviations applied to the parameters and the variations of the resulting limit elongations and stresses are determined, as well as the inverse relations relating the variations of the limit elongations and stresses to the parameter deviations. Knowing these inverse relations allows, in one or several stages, to find out the deviations to be applied in order to make up the measurable differences between the limit elongations and stresses of the optimized tube and the tube selected a priori.Type: GrantFiled: February 17, 1993Date of Patent: May 12, 1998Assignees: Institut Francais du Petrole, Societe AerospatialeInventors: Charles Sparks, Jacques Schmitt, Guy Metivaud, Marcel Auberon

Patent number: RE36687Abstract: A method and apparatus for manufacturing recyclable paper pallets utilizes spool-shaped laminated supports which are wound on a spool-shaped mandrel utilizing adhesive coated paper strips. In one aspect of the invention, the spool-shaped laminated supports can be glued to conventional upper and lower pallet skin sheets also made of paper material, such as corrugated paperboard. In another aspect of the invention, the spool-shaped pallet supports are utilized in a system in which the pallet is integrated directly into a pre-strapped load. In this system, a slip sheet is strapped directly to the bottom of a load and the slip sheet is glued directly to the upper faces of an array of pallet supports, sufficient to support the load and to provide the spacers or standoffs for subsequent insertion of lifting equipment, such as a lifting fork, beneath the load. The inherent rigidity of the strapped load may be sufficient to compensate for the lack of rigidity of the thin paper slip sheet.Type: GrantFiled: December 4, 1997Date of Patent: May 9, 2000Assignee: Marquip, Inc.Inventors: Carl R. Marschke, Harold D. Welch
