  • Method for light-assisted curing of coatings
    Patent number: 5562953
    Abstract: This invention relates to a method for light-assisted curing of coatings by providing coatings with an enamine content sufficient to enhance the cure rate of the coatings. The coatings exhibit improved weatherability and gloss retention when exposed to light.

  • Method and apparatus for providing privacy/security in a communication system
    Patent number: 4972479
    Abstract: Apparatus and methods are disclosed for providing privacy on communications systems which include radio links, such as cellular telephone, marine radiotelephone, IMTS, and RDSS systems, in a manner which does not require a scrambler/descrambler at each called party location. The apparatus includes a base module having a call diverter connected to the public switched telephone network through two standard telephone lines. A bypass interface circuit is connected to the call diverter between the connections to the two telephone lines to selectively connect a scrambler/descrambler in series with the two telephone lines.In operation, a mobile telephone, such as a cellular telephone, places a call to the telephone number of the first telephone line to cause the call diverter to place the second line off-hook and supply a dial tone from the second line through the call diverter and the first line back to the cellular telephone.
