Patents by Inventor Boyd A. Barnard

Boyd A. Barnard has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6036997
    Abstract: This invention relates to improved polymer-pressure sensitive adhesive combinations, particularly in the form of laminates, and methods of producing same. This invention improves the bond strength of the pressure sensitive adhesive to the polymer layer by priming the polymer surface with a curable urethane primer before applying the pressure sensitive adhesive to the polymer surface. If the polymer surface is not "active" to the curable urethane primer, the polymer surface is first activated with a silicon-containing treating agent. The laminates of this invention have superior bond strength, especially longterm bond strength. Of particular interest are the embodiments of this invention wherein the polymer is a silicone foam and the pressure sensitive adhesive is either acrylic or silicone adhesive.

  • Patent number: 5658634
    Abstract: A lightweight and resilient heat barrier laminate which provides sound and vibration dampening. The laminate has a density less than about 5 lb/ft.sup.3 and a total thickness of no greater than about 1 inch. The laminate includes a first metal foil having high heat conductivity and a first batt of insulating nonwoven fiber material having a thickness of at least about 0.03 inch. The first batt is an outermost layer of the laminate which is adhesively bonded to a first side of the first metal foil. The laminate also includes a second metal foil and a second batt of insulating nonwoven fiber material different from the material of the first batt. The second batt has a thickness of at least twice as thick as the first batt and is adhesively bonded to a second side of the first metal foil. The second metal foil is an outermost layer of the laminate, has high heat conductivity, is in contact with the second batt of insulating material and can be in contact with a carpet.

  • Patent number: 5408071
    Abstract: A heat distributing device which includes a concentrated heat source and a stack of metal foils wherein the heat source is encapsulated between two of the layers of metal foil. The heat source can be a resistance heated wire which extends linearly and has a free end spaced inwardly from an end of the stack. The outer edge of the stack can be open or sealed. The stack can include metal wool and/or insulating material between layers of the metal foil. The heat distributing device can be used to provide uniform heating across an outermost layer of the metal foil. For instance, the heat distributing device can be used to heat a side-view mirror of an automobile.
