  • Bloom-resistant benzotriazole UV absorbers and compositions stabilized therewith
    Patent number: 6380285
    Abstract: Benzotriazole UV absorbers substituted with a ultra long ester or amide moiety wherein the ester or amide group is a hydrocarbyl group of 25 to 100 carbon atoms or is a group of alkyl of 25 to 100 carbon atoms interrupted by 5 to 39 oxygen atoms and terminated with an omega-OH or an omega-OR group exhibit excellent stabilization efficacy while they concomitantly do not bloom when incorporated into polyolefin films. These benzotriazole UV absorbers also provide excellent protection to white, dyed, dipped, unscented and/or scented candle wax from discoloration and degradation.

  • Card cage shielding contactor
    Patent number: 5856632
    Abstract: A card cage shielding contactor for being interposed between a circuit card bracket and a computer chassis to enhance an electrical shielding connection between the circuit card bracket and the computer chassis when the card cage bracket is juxtaposed with the computer chassis, the card cage shielding contactor including a relatively thin, flexible sheet of electrically conductive material having a multiplicity of contactors in the form of resiliently deflectable fingers located along bands in the sheet and projecting from the bands to establish contact forces enhancing electrical shielding contact between the circuit card bracket and the computer chassis through the card cage shielding contactor.
