Title: Closed system virtual postage meter
Inventor: RYAN FREDERICK W
IPC: H04L9/32
Filed: 1998-12-16
Abstract: A system and method for evidencing postage on a mailpiece includes a printer module transmitting to a remote data center a request for indicia data. The data center includes a processor, a database and a secure coprocessor. The database includes user account data. The request includes postal value for a selected number of indicia to be printed by the printer module. The data center verifies that the printer module is authorized to request the postal value and retrieves user account data stored in a database. The data center verifies the user's account data includes sufficient funds for the number of indicia requested, debits the user's account data for the total postal value requested and then generates a digital token for each of the indicia. The digital token is generated from information relating to each of the indicia including information unique to each of the indicia. The data center transmits to the printer module the requested indicia data including postal value and digital token for each of the indicia. The printer module prints the received indicia.:

Title: Configuration of cooling channels for cooling the trailing edge of gas turbine vanes
Inventor: HULTGREN KENT GORAN
IPC: F01D5/18
Filed: 1998-03-25
Abstract: An apparatus for cooling the trailing edge portion of a gas turbine vane. Two radially extending passages connected to the outer shroud direct cooling fluid to a plenum formed about mid-span adjacent the trailing edge. Two arrays of cooling fluid passages extend from the plenum.      One array extends radially outward toward the outer shroud while the other array extends radially inward toward the inner shroud. The plenum distributes the cooling fluid to the two arrays of passages so that it flows radially inward and outward to manifolds formed in the inner and outer shrouds, The manifolds direct the spent cooling fluid to a discharge passage.

Title: Improved boot and method of making such a boot
Inventor: SADR CHANGIZE
IPC: B29C49/42
Filed: 1997-01-21
Abstract: A blow molded product which is generally tubular having first and second open ends and, a bellows section intermediate said first and second ends, so that said product is flexible, has a skirt adjacent one of said first and second ends. The bellows section is formed in a blow molding operation and the skirt section is formed by compression molding. A preferred embodiment of the product has a rib extending internally of the wall of the blow molded section to strengthen the transition region between the bellows section and the skirt section. The steps of the process include confining a parison in a mold and then introducing a core into the parison in the mold. The core moves thermoplastic material axially and possibly also radially and circumferentially.      This process enables molding of a product with an external surface which may be substantially cylindrical with an internal surface which has lobes, ribs, or other internal projections.
