Patent CA-2427830-A1 (CA)
Inventor: KUCHEROVSKY JOSEPH S
IPC: A24D1/02
Filed: 2001-11-13
Abstract: A process for reducing the permeability of a paper wrapper (14) used in the construction of a smoking article (10) is disclosed. The paper wrapper (14) is treated with a film-forming composition (52) that forms treated discrete areas (18) on the wrapper. The treated discrete areas (18) have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article (10) made with the wrapper (14). In accordance with the present invention, the film-forming composition (52) is applied as multiple layers (31, 33, 35) to the paper wrapper 14). After each application step, the wrapper (14) is dried. Applying the film-forming composition (52) to the paper wrapper (14) in multiple layers (31, 33, 35) minimizes distortion and other adverse affects that may occur to the wrapper (14).

Title: Mirroring network data to establish virtual storage area network
Inventor: OHRAN MICHAEL R
IPC: G06F17/30
Filed: 2002-06-25
Abstract: Mirroring data to provide a virtual storage area network (340) using policing protocols (311, 321) and mirror engines (317, 327) without a physical shared storage node. The mirror engines (317, 327) are found at each server computer (310, 320) in the network (301) in order to mirror the data between mass storage devices (319, 329) of the servers (310, 320) as the servers receive and execute write operations, which results in each mass storage device containing the same stored data. The policing protocols (311, 321) prevent data corruption by not allowing more than one server (310, 320) at a time write to a file of data. If one server (310, 320) experiences failure and is incapable of providing access to network data, the other server or servers can service all read requests, since all network data is accessible by all servers. Unlike conventional storage area networks, there is no physical shared storage node and, accordingly, the costs of obtaining and operating the virtual storage area network (340) are relatively small.
