Title: System for accounting for postage expended by a postage meter having data security during editing of accounts
Inventor: MAMONE JOHN R
IPC: G06Q20/20
Filed: 1986-12-24
Granted: 1991-02-05
Abstract: ABSTRACT OF THE DISCLOSURE      A system for accounting for postage expended by a postage meter.  The system includes a keyboard and display for entry of commands and postal information, a printer, a memory for storing account records and program data, the memory further including a non-volatile memory for storing account records and other data, an interface to an electronic postage meter, and a processor including a CPU.  The processor controls an electronic postage meter through the interface in accordance with the program data and entered postal information to set the meter and then responds to signals from the meter to update account records.  The processor may also edit selected account records in accordance with entered information.  In one disclosed embodiment the system responds to an operator request to print the account data base by repetitively scanning the account data base and sequentially printing accounts.  In another disclosed embodiment the system stores images of accounts to be edited in selected regions of non-volatile memory before beginning to edit the account.  These embodiments increase the security of the data in the accounts by avoiding exposure to data loss due to power failures or transients while accounts are being processed.  In another disclosed embodiment a record of edited accounts is maintained by the system to allow a service technician to detect unauthorized editing of accounts.  In still another disclosed embodiment the system tracks the contents of the postage meter ascending register to detect off-line meter usage.

Filed: 1987-04-06
Granted: 1990-12-11
Abstract: ABSTRACT   The present invention relates to single and twisted pair transmission line wires wherein the effective electrical diameter of the primary conductor is increased.  This is accomplished by wrapping conductive foil or conductive foil laminated to a substrate layer onto a primary conductor with a diameter less than 20 mils wherein the foil is in contact with the conductor and has an outer insulating cover.   This may be done by either spiral wrapping or by longitudinal wrapping around the electrical conductor.  This invention provides a desired characteristic impedance along the length of the wire(s) and allows easy removal for standard termination and increased cut-through resistance.

Title: System and method for removing volatile components from an aqueous medium
Inventor: ROBBINS LANNY A
IPC: C02F1/20
Filed: 1987-06-25
Granted: 1992-03-10
Abstract: ABSTRACT     A system and a method are disclosed for removing dissolved organic impurities, such as gasoline or other hydrocarbons, from contaminated water.  The contaminated water is fed into a stripper column, operated under a vacuum, to enable the water to enter the column at its boiling point.  Steam, as a vaporizing gas, strips the impurities out of the water and the overhead vapor phase is compressed to boost it to a higher pressure, so it can be condensed to vaporize part of the bottoms stream from the column.         Since the bottoms stream is mostly water, the vapor generated is the steam used to strip impurities from the water.     34,818-F

Abstract: "PROCESS FOR EXTRACTING PARAFFINS FROM THEIR MIXTURES   WITH ALKANESULPHONIC ACIDS"            ABSTRACT OF THE DISCLOSURE            In preparing alkanesulphonic acids by sulphoxidation of n-paraffins containing between 12 and 18 carbon atoms,  using UV radiation to initiate the reaction (light-water process), a mixture is obtained which spontaneously allows a substantial part of the unconverted n-paraffins to separate from a mixture containing the alkanesulphonic acids together with water, sulphuric acid and n-paraffins.  The aforesaid mixture is fed with one or more alcohols having four or less than four carbon atoms,  preferably isopropanol,  to form a two-phase mixture.  The two-phase mixture is extracted with supercritical CO2, which extracts the n-paraffins, these being recycled to the sulphoxidation process.  The paraffin-free product is suitable for preparing alkanesulphonates of the desired type by neutralisation with suitable bases.
