  • Patent number: 7771577
    Abstract: Processes for forming a coating on electroconductive flat blanks having two major surfaces and sheared edges are provided. Also provided is a process for forming a multi-composite coating on a pre-sheared, electroconductive, flat blank having two major surfaces and sheared edges. Methods for forming and coating metal blanks are also provided. The present invention further provides a pre-sheared, flat electroconductive blank having two major surfaces and coated with a multi-layer composite coating composition on one major surface.

  • Patent number: 6396851
    Abstract: A method of facilitating telephony communications over a packet-switched network includes detecting signaling tones in an audio stream and blocking them from the stream in response to the detecting. After the blocking, the audio stream is sent over an undependable channel in the packet-switched network. The detected signaling tones can be sent over a dependable channel instead of the undependable audio channel.
