Patent number: 7223469Abstract: Moldable capsules of a conductive loaded resin-based material are created. The moldable capsules include a conductive element core radially surrounded by a resin-based material. The conductive loaded resin-based material includes micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The conductive element core includes between about 20% and about 50% of the total weight of the moldable capsule in one embodiment, between about 20% and about 40% in another embodiment, between about 25% and about 35% in another embodiment, and about 30% in another embodiment. The micron conductive powders are formed from non-metals, that may also be metallic plated, or from metals, that may also be metallic plated, or from a combination of non-metal, plated, or in combination with, metal powders. The micron conductor fibers preferably are of nickel plated carbon fiber, stainless steel fiber, copper fiber, silver fiber, or the like.Type: GrantFiled: July 1, 2004Date of Patent: May 29, 2007Assignee: Integral Technologies, Inc.Inventor: Thomas Aisenbrey

Patent number: 7166354Abstract: The present invention provides a metal coated fiber with excellent coating strength and corrosion resistance, and a conductive resin composition with excellent conductivity. A feature of a metal coated fiber of the present invention is that following provision of a metal coating on the surface of the fiber, heat treatment is conducted at a temperature greater than the crystallization temperature but less than the melting temperature of the fiber. Gradual cooling is preferably performed following the heat treatment. Furthermore, a conductive metal coating may be provided as the metal coating, and an additional corrosion resistant metal coating then laminated onto the surface of the conductive metal coating. In addition, a feature of a conductive resin composition of the present invention is that metal coated short fibers, formed by providing a conductive metal coating on the surface of a substrate fiber formed from a synthetic resin and then conducting heat treatment, are mixed into a substrate resin.Type: GrantFiled: October 26, 2001Date of Patent: January 23, 2007Assignees: Mitsubishi Materials Corporation, Japan Electric Metals Corporation, LimitedInventors: Makoto Tsunashima, Yuusuke Maeda, Nobuo Furuya

Patent number: 7132378Abstract: Improvements in the high-temperature wash durability and discoloration levels for fabrics having topically applied silver-ion treatments (such as ion-exchange compounds, like zirconium phosphates, glasses and/or zeolites) are provided. Such solid compounds are generally susceptible to discoloration and, due to the solid nature thereof, are typically easy to remove from topical surface applications, particularly when laundered at elevated temperatures. The inventive treatment requires the presence of a specific cross-linked binder, either as a silver-ion overcoat or as a padded-on component of a cross-linked binder admixed with the silver-ion antimicrobial compound. In addition, specific metal halide additives (preferably substantially free from sodium ions) may be utilized to combat the discolorations typical of such silver-ion formulations.Type: GrantFiled: April 23, 2003Date of Patent: November 7, 2006Assignee: Milliken & CompanyInventors: Jason Kreider, Shulong Li

Patent number: RE39490Abstract: A security device having multiple security features is used with an item, such as a secure document, ticket, label or tag, to authenticate the item and/or encode data pertaining to the item. One example of the security device includes a carrier substrate, a metallic layer disposed on the carrier substrate, and a magnetic layer disposed on the metallic layer in substantial registration with at least a portion of the metallic layer, thereby providing both metallic security features and magnetic security features. The metallic layer and the magnetic layer also form graphic or visually identifiable indicia on the carrier substrate to provide a visual security feature. According to one method, the metallic layer is applied to the carrier substrate, the magnetic layer is applied to the metallic layer, and the layers are etched to form the graphic indicia. The magnetic layer can, in one embodiment, include a magnetic chemical resist that is printed on the metallic layer in the form of the graphic indicia.Type: GrantFiled: July 1, 2003Date of Patent: February 20, 2007Assignee: Technical Graphics, Inc.Inventors: Paul F.
