Abstract: A method and apparatus for preventing recognition by a telephone system of a telephone dialing signal which inverts at least a portion of the telephone dialing signal in response to receiving the telephone dialing signal. Consequently, an inverted dialing signal is produced and is combined with the telephone dialing signal. Voice and data signals are unaffected. The telephone dialing signal is then connected to the telephone system and is unrecognizable as a valid number.

Abstract: In an apparatus for processing and serially dispensing discrete groups of documents, a system for identifying and sequentially arranging a plurality of coded documents traveling in a stream. The documents are conveyed individually from a source to a release position and, during the time that they are being conveyed, they are scanned to determine the presence of a document and also to read code which appears on the document. That information is stored in a processor. Documents are retained or released at a document retention gate depending on the nature of the code read from the document. A document accumulator is spaced down stream from the retention gate and includes an accumulation gate and a scanner to determine presence of documents at the accumulation gate. Documents pass through the system and exit from the accumulation gate depending on the code from each document.
