Patent number: 6455100Abstract: 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: April 13, 2000Date of Patent: September 24, 2002Assignee: Elisha Technologies Co LLCInventors: Robert L.

Patent number: 6399021Abstract: A system is disclosed for inhibiting the corrosion of ferrous and other metals by passivating the metals. The system includes novel buffered compositions which may be applied to metal products, and novel combinations thereof with metals, for preventing or retarding corrosion, as well as methods for applying the buffered compositions to metal products, such that corrosion protection of the products is achieved. The methods include an in-situ application to existing structures with metal reinforcement as well as applications to metal products during manufacture. Generally, the compositions may be in various forms and comprise one or more layers, at least one of which includes a water repellent but water vapor permeable carrier component and one or more pH buffer components. The buffer is selected to produce a passivating pH at the surface of the metal.Type: GrantFiled: June 30, 2000Date of Patent: June 4, 2002Assignee: Elisha Technologies Co LLCInventors: Robert L. Heimann, William M. Dalton, David R. Webb, Nancy M. McGowan

Patent number: 6386601Abstract: 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: August 31, 1999Date of Patent: May 14, 2002Assignee: Elisha Technologies Co LLCInventors: Robert L. Heimann, Wayne L. Soucie
