Patent number: 7541095Abstract: The disclosed invention relates to black multi-layer coatings for metallic substrates (1) or substrates having a metallic coating (2) and to articles covered, or partially covered with such coatings. The black coating consists of a black first layer (3) substantially comprised of nickel and a second polymeric silicate inorganic layer (4). The present invention may additionally have a third layer comprised substantially of organic constituents (5). This invention offers properties currently unavailable or insufficient in existing technologies. The present invention provides enhanced corrosion resistant, adherent black coatings which are thin enough to allow application to fasteners while providing a uniform black color, the combination of which have only been available previously with the use of hexavalent or trivalent chromium conversion coatings.Type: GrantFiled: October 26, 2007Date of Patent: June 2, 2009Assignees: Elisha Holding LLC, Kismart CorporationInventors: Wan-Chu Wu, Wei-Liang Yang, Wen-Chi Chang

Patent number: 7160630Abstract: The disclosure relates to a corrosion resistant article comprising a metal body and a protective coating applied on at least one surface of said metal body, said protective coating comprising: (a) a zinc layer comprising metallic zinc; (b) a silicate layer comprising at least one silicate; and (c) a lubricant layer comprising at least one lubricant such as, for example, polyethylene wax. In particular, the disclosure relates to a corrosion resistant bolt and/or nut having a protective coating for use in motor vehicles. The protective coating is substantially free of chromates and phosphates and, hence, environmentally acceptable. The article has an excellent coefficient of friction, temperature resistance and anti-corrosion properties.Type: GrantFiled: May 31, 2005Date of Patent: January 9, 2007Assignee: Elisha Holding LLCInventor: Klaus-Peter Klos

Patent number: 6995484Abstract: A method is disclosed for providing inorganic and/or organic coating compositions onto rotor cores to eliminate soldering during aluminum injection. These coatings can also be applied upon electric motor rotors and/or stators laminates as well as other electronic components such as transformers. The disclosed method provides at least one film or layer of a coating composition within channels or bar slots defined by the rotor of the electric motor core/rotor (depending upon the design of the motor the slots can be defined within the rotor or open ended along the longitudinal axis of the rotor). The coating composition is also typically applied upon all exposed surfaces of the rotor, e.g., within the channels and exterior surfaces of the rotor. The coated rotor is then contacted with a molten metal. The coating composition functions to isolate the laminates (e.g., steel) of the rotor from a molten metal (e.g.Type: GrantFiled: May 24, 2000Date of Patent: February 7, 2006Assignee: Elisha Holding LLCInventors: Robert L.

Patent number: 6705651Abstract: A latching mechanism that uses lubricant impregnated bearings to improve the operation, reduce the corrosion, ease the maintenance, and extend the life of the latching mechanism. The latching mechanism comprises a spindle rotatably disposed in a sleeve that is fixed to a frame (e.g., a door frame). Positioned in the annular space between the spindle and sleeve, the lubricant impregnated bearings separate dissimilar materials and provide a constant source of lubrication. To replenish the bearings, lubricant is introduced into the annular space through a channel in the spindle that communicates between an inlet opening in the end of the spindle and an outlet opening at the annular space. The lubricant impregnated bearings are grooved to enhance lubricant flow and distribution around the bearing surfaces. A shield is attached to the spindle and is disposed around the exterior of the sleeve to prevent debris from entering the annular space.Type: GrantFiled: March 8, 2002Date of Patent: March 16, 2004Assignee: Elisha Holding LLCInventors: Robert L. Heimann, Wayne L. Soucie
