Louis J. Hillenbrand 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: 4557807
    Abstract: A novel in-mold electrodeposition process is disclosed for the production of plastic parts having conductive polymeric coatings such as polypyrroles or polythiophenes. Parts produced according to the novel disclosed in-mold electrodeposition process would have wide applicability including static free plastic parts shielding devices and circuits. The disclosed process advances the art by enabling the utilization of conductive polymers many of which were heretofore considered too brittle for commercial adaptation.

  • Patent number: 4105014
    Abstract: Acid and base catalyst substances are employed in the photochemical process for collection and retrieval of solar energy wherein a lower energy level isomer (e.g. trans-isomer) of a photochemical isomerizable compound is exposed to solar energy of a wavelength providing a higher energy level isomer (e.g. cis-isomer) of this isomerizable compound and this higher energy level isomer subsequently is transformed to its lower energy level isomer with exothermic release of thermal energy for useful purposes. In this process the transforming or conversion of the higher energy level isomer to its lower energy level isomer is facilitated by the presence of and/or contacting with the acid or base catalyst substance.
