  • Publication number: 20030126215
    Abstract: A self-destructing document or e-mail messaging system is provided that automatically destroys documents or e-mail messages at a predetermined time by attaching a “virus” to the document or e-mail message. A virus in the form of a Trojan horse is attached to file (such as an e-mail message or document) when it is created. The virus contains a portion of executable code or an executable program which instructs the computer to overwrite and/or delete the file to which the virus is attached at a desired time. Since the virus is attached to the file, it will travel with the file even when the file is copied, forwarded, or saved to disks or tape drives.

  • Patent number: 3950495
    Abstract: An improved method for the continuous production of stable aqueous ammonium polyphosphate compositions which are useful as fertilizers and fire retardants. Wet-process superphosphoric acid which is primarily in the orthophosphate form and anhydrous ammonia vapor are combined in a pipe reactor wherein the exothermic ammoniation of the acid and the conversion of a portion of the orthophosphate to polyphosphate caused by the heat liberated in the exothermic ammoniation reaction occur. A stream of the acid is introduced into the interior of a stream of ammonia vapor in the pipe reactor in order to avoid corrosion of the pipe reactor.Water is added to the reaction mixture to quench the conversion reaction and to provide the amount of water that is required in the desired final composition. The resulting stream is combined with a cooler stream of the desired final stable aqueous ammonium polyphosphate wherein the polyphosphate is cooled and the ammoniation is completed rapidly.
