Gilbert G. Berg 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).

  • Process for producing high gloss laminates using a vapor barrier at each end of a laminate assembly
    Patent number: 4599127
    Abstract: A laminate assembly, containing press plates having smooth polished sides and laminate stack-up sets, for producing high gloss laminates, is molded using a vapor impermeable barrier layer positioned between stack-ups in the stack-up set next to the exterior press plates, so that during the fast heatup of that stack-up set during molding, vapor travel toward the interior of the assembly is controlled, preventing vapor buildup, and low gloss areas on certain laminates.

  • Method utilizing ultrasonically induced cavitation to impregnate porous sheet passing through a resin bath
    Patent number: 4552781
    Abstract: A method of impregnating a flexible, porous cellulosic sheet material involves passing the sheet through a low viscosity resin and across the resonant vibrating surface and through a cavitated zone in close proximity to at least one completely immersed ultrasonic wave generator, operating at a frequency and radiated power level effective to provide a combination vibratory pressure on the resin and cavitation effect causing degassing and heating of the resin, followed by passing the impregnated sheet through a drying means.
