Abstract: A wireless, redundant, secure, real-time, network for a proprietary interactive data transfer system having a remote terminal and a host data center, such as an automated teller banking system, is disclosed. Controllers for the remote terminal and the host data center receive the proprietary language messages and packetize and encrypt the messages for sending over the best wireless carrier among the plurality of wireless carriers the controllers are connected to. The wireless control protocol monitors the communications to provide for selection of the most reliable communication carrier for any part of a transmission. Each network segment of the signal path has at least one state-controlled gate which reports the status of that signal path. Real time transmission and acknowledgment of securely packetized messages on wireless communications carriers via an object oriented coding control application provides for reliable datagram transfer independent of the reliability of any one signal path.

Abstract: The organic chemical waste content of contaminated materials such as soils and debris is immobilized by mixing such wastes with an agent consisting of a mixture of particulate rubber and biogenic amorphous silica. Where the semi-volatile content of the waste is known to predominate a greater portion of particulate rubber is advantageous and where such waste is known to be entirely semi-volatile organic material such agent advantageously consists essentially or comprises particulate rubber. Conversely, where the organic content of such wastes is predominately volatile organic material a greater portion of biogenic amorphous silica should be employed and where such organic waste is known to be entirely volatile organic such additive is advantageously biogenic amorphous silica.
