    摘要: The postage meter terminal has the ability to telecommunicate with a remote central computer for the principal purpose of remotely resetting the funding registers of the postage meter terminal. During the telecommunication and subsequent to completing meter recharge, the postage meter terminal can be remotely inspected by the central computer. The terminal includes a microprocessor control system which is programmed to generating inspection data and store that data in a memory unit. The microprocessor control system also includes a random number generator for generating a random number within a limited range. Each number within the range of random number selections corresponds to a respective scrambling technique executable by the microprocessor system. The method of remote inspection is carried out by the microprocessor control system storing desired inspection data in the terminal memory unit generating a random number and then creating a data word of the inspection data and the random number. The data word is then partitioned into a first and second partition. The first partition of the data word including the random number selection at a predetermined bit location within the first data word portion. The second partition of the data word is scrambled pursuant to the scrambling techniques which corresponds to the random number. The data word may then be encrypted utilizing the encryption key which was generated during the remote reset process and communicating the data to the central computer via the communication port. The central computer can then decrypt the encrypted data word since it is aware of the encryption key used to complete the remote meter reset. The central computer then retrieves the random number and descrambles the second portion of the data work according. The central computer is thereby informed of the inspection data for that particular postage meter terminal.

    摘要: A process for installing a liner in a generally horizontal pipe section includes the steps of: providing a hollow generally cylindrical folded pipe liner having a reduced cross section sized to allow the liner to be slidably drawn into the pipe section from an upstream end to a downstream end; pulling the folded liner through the pipe section leaving end sections of the liner extending from the upstream end and the downstream end of the pipe; snaking a pull wire through the liner; pulling an air hose and a steam hose through the folded liner from the downstream end to the upstream end; providing a floating plug assembly including at least two disk shaped expanders; attaching the steam hose to the floating plug assembly downstream of the disk shaped expanders; attaching the air hose to the floating plug assembly upstream of the disk shaped expanders; inserting the floating plug assembly into the liner at the upstream end; and providing steam to the steam hose and cooling air to the air hose, while pulling the floating plug assembly through the liner to progressively heat the liner to a softening point downstream of the disk shaped expanders, and expand the liner to fill the pipe and cool the expanding liner upstream of the disk shaped expanders.

    摘要: A method for printing a postal indicia on a mailpiece includes moving a printing mechanism and the mailpiece relative to each other during a plurality of passes; and printing with the printing mechanism at least a corresponding portion of the postal indicia during each of the plurality of passes, each of the corresponding portions being in overlapped relationship to the other corresponding portions so that the combined effect of the corresponding overlapped portions is a postal indicia which is detectable by a facer/canceler machine as a valid postal indicia. Furthermore, during no more than one of the plurality of passes is its corresponding portion of the postal indicia detectable by the facer/canceler machine as the valid postal indicia. An apparatus incorporates the above method.

    摘要: A method and apparatus for generating cryptographic keys for a postal manifest and for synchronizing cryptographic keys for transmitting postal data securely on a communication link is presented. The techniques for generating a key and for synchronizing keys use the same apparatus but use slightly different data to create a cryptographic key.The postal data center maintains a unique set of data for each server station. Using this set of data along with a manifest sequence number (or communication transaction number) and the date, a cryptographic key is created. Each server station stores a fixed master key, KO, a permutation table, Pt, and ID, and GMT date. Using the manifest sequence number (or the communication transaction number) a row of the permutation table is altered and the master key KO is scrambled with the permutation table top get a new key K2. With K2, the date, server ID, and manifest sequence number (our communication transaction number) are encrypted. The result of this encryption yields another key K3. K3 is then used for encrypting the postal manifest or for communicating with a postal data center.
