Patent number: 6565946Abstract: A machine which inflates and seals pillows in packaging is compact in overall size, can be conveniently operated to produce varied lengths of strips of inflated pillow-type packaging as needed, can begin production of inflated pillow-type strip packaging immediately after being held out of a production cycle for some period of time, and applies a heated sealing element directly to and in sliding contact with a web of film to securely seal the inlet port of an inflated pillow while the pillow is under pressure and as the web of film is continuously and uninterruptedly advanced through the machine.Type: GrantFiled: March 26, 2002Date of Patent: May 20, 2003Assignee: Free-Flowing Packaging International, Inc.Inventors: Andrew Perkins, Oliver M. Reyes, Philipp Borchard, Nicholas P. De Luca

Publication number: 20030087051Abstract: Insulating packaging material is wrapped or otherwise positioned around the typically temperature sensitive product, with the packing material including, alternatively, 1 ply (FIG. 22; metallized plastic film), 2 ply (FIGS. 23 & 24) and 3 ply (FIG. 25) material, in which some of the 2 ply & 3 ply embodiments include a layer of bubble wrap material having its bubble side placed or laminated against the flat side of the adjacent ply, which adjacent ply can be, for example, a mettalized plastic film or a foam layer or both layers can be included. With such a bubble side arrangement, multitudinous air pockets are formed between the bubbles of the bubble wrap and the other ply's typically flat interfacing surface. A separate layer of bubble wrap also preferably is placed about the interior of the box with its bubble side placed against the interior flat surfaces of the box, with the bubbles forming air pockets with the flat sides, further enhancing the insulating properties of the packaging for the goods.Type: ApplicationFiled: August 1, 2001Publication date: May 8, 2003Inventor: Joseph C. Murray

Patent number: 6555203Abstract: The invention regards a material having a three-dimensional surface built up by bulgings arranged regularly or irregularly mutually adjacently, and which have approximately conical form. It is thus accomplished that the brightness of the material is little dependent on the view angle, in contrast to what is the case with plane surfaces, even if painted with matte camouflage paint.Type: GrantFiled: April 27, 2001Date of Patent: April 29, 2003Assignee: Barracuda Technologies ABInventor: Lars Karlsson

Patent number: 6544624Abstract: A modular fiber reinforced polymer (FRP) composite deck module having one or more hexagonal components and one or more double trapezoidal components. A hexagonal component is a hexagonal cell with all sides being of equal length and forming a hexagonal space. A double trapezoidal component has a top side, a bottom side, a first trapezoid having a first top and a first bottom, and a second trapezoid having a second top and a second bottom. The first and second trapezoidal components are of equal dimensions and configured such that the first trapezoid is inverted resulting in the first top of the first trapezoid is adjacent to the second top of the second trapezoid, thereby creating a center seam and an extensive bonding surface. The double trapezoidal and hexagonal components are made of multiple layers of multi-axial fiber reinforcement and a resin matrix, the layers being continuous throughout the entire shape of the components.Type: GrantFiled: June 13, 2002Date of Patent: April 8, 2003Assignee: West Virginia University Research Corp.Inventors: Roberto A. Lopez-Anido, GangaRao V. S. Hota, Ever J. Barbero

Patent number: 6541095Abstract: The invention relates to a flattened tubular film (1) made of thermoplastic material, in which the inner faces are not welded or glued, and are in mutual contact only over a part of their surface, thus forming a plurality of cells (3) of determined shape, essentially hermetic, containing a gas. The invention also relates to a process for manufacturing such a film, by extruding a preform, introducing a gas into the preform and flattening using at least one cylinder (2) whose surface has a relief such that, during the flattening, the two inner faces of the film come into mutual contact only over a part of their surface, thus forming a plurality of cells of determined shape, substantially hermetic, in which the said gas is imprisoned.Type: GrantFiled: January 15, 1999Date of Patent: April 1, 2003Assignee: Solvay (Societe Anonyme)Inventor: Nicolaas C. Van Der Pouw

Patent number: 6537639Abstract: A buffer air cushion has an outer air cushion and an inner air cushion disposed in the outer air cushion. The outer air cushion is inflated with a smaller inner pressure than that of the inner air cushion so that the buffer air cushion may have better pressure elasticity and shock-absorbing functions.Type: GrantFiled: September 6, 2000Date of Patent: March 25, 2003Inventor: Ing-Chung Huang

Patent number: 6530191Abstract: A support panel for use in an air handling unit for both supporting equipment inside the unit and providing a thermal barrier to the flow of heat into and out of the unit. The panel includes a plastic frame that is enclosed by upper and lower covers to form an internal cavity. Support members are placed in the cavity between the covers to which equipment that is supported upon the panel can be secured. The support members are fabricated of a high strength composite material having a low thermal conductivity. A curable foam is then injected into the cavity to bond the panel components together in assembly. The frame, the support members and the curable foam all have a relatively low thermal conductivity and coact to create a thermal barrier to impede the flow of heat in or out of the unit.Type: GrantFiled: July 13, 2001Date of Patent: March 11, 2003Assignee: Carrier CorporationInventors: Edward T. Rieke, Michael W. Austin
