Patent number: 6312548Abstract: The bonding of components is facilitated by a conductive pattern which generates heat upon being irradiated with microwave or RF energy. The electrically conductive pattern is positioned on a first component surface and a curable resin having adhesive properties is applied thereto. A second component surface is placed in contacting relation with the resin and the conductive pattern is irradiated with microwave or RF energy to facilitate curing wherein the components are bonded together along the pattern. The conductive pattern can be utilized without adhesive resin wherein heat generated via the application of microwave or RF energy causes components to fuse together. The conductive pattern can be enveloped by polymeric material, wherein the polymeric material becomes the adhesive for bonding components when microwave or RF energy is applied.Type: GrantFiled: March 29, 1996Date of Patent: November 6, 2001Assignee: Lambda TechnologiesInventors: Zakaryae Fathi, Richard S. Garard, Jianghua Wei

Patent number: 6302993Abstract: The invention provides a process, and product thereof, for forming a chemically resistant fusion bonded between chemically dissimilar materials by use of an acid-based terpolymer for protective garments. The olefin terpolymers are preferably copolymers of an olefin, an acid and an ester. The process involves placing the olefin terpolymer film between two dissimilar films such as a facepiece and the fabric material of the garments and applying heat and pressure. The resulting fusion bonded film composite is strong, flexible and upon the application of sufficient stress exhibits total cohesive rupture failure.Type: GrantFiled: October 1, 1998Date of Patent: October 16, 2001Assignee: LakeLand IndustriesInventors: W. Novis Smith, Joel McCloskey, Kelly Bradford

Patent number: 6238805Abstract: A low-stress interface between materials having different thermal coefficients of expansion and method for fabricating same includes using a laminated composite layer having a lateral thermal coefficient of expansion (TCE) that is matched to the TCE of another layer of material that is joined thereto. Using a laminate material having a lateral TCE similar to the TCE of the material to which it is joined equalizes the lateral thermal expansion of the two materials at the interface therebetween and minimizes the stress placed on the material that joins the two materials. Furthermore, the layer of material to which the laminate is joined can also be a laminate.Type: GrantFiled: October 8, 1999Date of Patent: May 29, 2001Assignee: Agilent Technologies, Inc.Inventor: Phillip W.

Publication number: 20010000585Abstract: This invention relates to making nonwoven fabrics which are durable for machine washing and durable for other wet and hard use or abusive applications. The inventive fabrics comprise two layers of fabric sheet bonded together at closely spaced locations where the bonding includes fibers from both fabrics thoroughly involved with the binder. The inventive fabrics retain the qualities of a spunlaced nonwoven fabric which include low cost, comfort, drapability, softness, absorbency, breathability and others while having the durability comparable to traditional knitted or woven fabrics.Type: ApplicationFiled: December 7, 2000Publication date: May 3, 2001Inventors: Charles C. Cruise, Robert H. Peterson, James T. Summers

Patent number: 6210522Abstract: An adhesive bonding laminate includes a first thermoplastic adhesive film that is capable of adhesively bonding to an epoxy coating and a second thermoset adhesive film that is capable of adhesively bonding to a passivated surface of a substrate. The first thermoplastic adhesive film is adhesively bonded to the second thermoset adhesive film. Ink jet printheads, ink jet print cartridges and methods of attaching a flexible circuit to substrate employ the adhesive bonding laminate.Type: GrantFiled: June 15, 1999Date of Patent: April 3, 2001Assignee: Lexmark International, Inc.Inventors: Jeanne Marie Saldanha Singh, Paul Timothy Spivey
