Patent Images
1. A radio facsimile postal system providing privacy in the transmission of a written message from the sender of the message to its intended recipient, comprising:
- first means providing said message for transmission to said intended recipient;
second means cooperating with said first means for generating image signals representative of said message including the name and address of said recipient;
third means responsive to the image signals representative of the name and address of said recipient for providing category code signals uniquely identifying said recipient and for multipleXing said code signals with the image signals representative of said message to form a composite radio facsimile signal for direct transmission to said recipient and in which the code signals precede the message image signals;
fourth means for transmitting said composite radio facsimile signal including the assigned code signal uniquely identifying the intended recipient and the image message signal intended for his receipt into a geographical area in which said recipient is located are in which are located great numbers of other possible recipients of the intended message but each identified by differing category codes; and
fifth means located at the address of the intended recipient for receiving said composite signals and conditioned to reproduce only those messages at his address location which are accompanied by said unique code signal assigned to him;
whereby privacy of transmission is fostered since said image message signal will only be reproduced at the address of the intended recipient to the exclusion of said other possible recipients in the same geographical area into which said composite signal is transmitted and since no intervening human factor forms part of the transmission system.

- first means providing said message for transmission to said intended recipient;
-
2. The system of claim 1 wherein said fourth means includes a microwave transmitter beamed at a relay satellite in synchronous equatorial orbit serving the geographical area in which said intended recipient and said other possible recipients are located.
-
3. The system of claim 1 wherein said fourth means includes a community antenna television network serving the geographical area in which said intended recipient and said other possible recipients are located.
-
4. The system of claim 1 wherein there is also included sixth means for returning said written message to the sender thereof after the generation of image signals representative of the message to further enhance privacy in the message transmission as no human factor need intervene in order to destroy the message after the transmission thereof.
