Title: System and method for backing up computer files over a wide area computer network
Inventor: MCCLAIN FRED W
IPC: G06F13/00
Filed: 1997-11-28
Abstract: A system backs up computer files to a remote site (12) via modem (16). Files of a user computer (24) that are found in a common library (20) at the remote site (12) are not copied to the remote site, whereas files not in the library (20) are copied to the remote site. Then, periodically the user computer (24) determines which blocks have been changed, and the user computer (24) transmits only changed blocks to the remote site (12). The blocks are gathered in "chunk" files (76), and when a chunk file reaches a predetermined size (78), it is transmitted to the remote site (12) for updating the back up version of the respective file. The process then resumes identifying changed blocks. In addition to flagging the changed block for transfer, the process resynchronizes the local data file with the backed up version using a two-step comparison, first comparing the first two characters in the block with a prestored character set, and then, if the first comparison results in a match, comparing a digital signature of the changed block with a pre-stored signature. If either comparison results in a mismatch, the test is repeated using, as the first byte of the test block, the next byte in the sequence.

Title: Plasminogen activator as an anti-inflammatory agent
Inventor: STRINGER KATHLEEN A
IPC: A61K38/49
Filed: 1998-01-29
Abstract: Plasminogen activator acts as an anti-inflammatory agent by inhibiting generation of superoxide anion by a mechanism that is not related to L-arginine, is not dependent on thrombolytic activity, and is not a function of oxygen free radical scavenging. Moreover, in in vivo models of inflammation, treatment with plasminogen activator reduces edema without inhibiting neutrophil infiltration in in vivo models of inflammation.
Patent CA-2279164-A1 (CA)
Title: Non-hazing uv curable powder coatings containing crystalline resins
Inventor: MUTHIAH JENO
IPC: C08F2/46
Filed: 1999-07-30
Abstract: This invention provides a UV curable powder coating composition comprising a particulate blend of a non-crystalline unsaturated polyester base resin, a crystalline unsaturated crosslinker resin co-polymerizable with the base resin, and a photoinitiator, that exhibits reduced or eliminated having in the cured coating formed therefrom upon being cured at low temperatures demanded by certain heat sensitive substrates. This is accomplished by incorporating in the powder composition a recrystallization or haze inhibitor which is comprised of a crystalline epoxy resin. When this powder blend is melted for curing, the crystalline crosslinker resin visually appears to separate and recrystallize out of the molten powder less completely than it does in the absence of the recrystallization or haze inhibitor. This prevents a visible haze from developing on the surface of the coating upon curing with UV radiation.

Title: Gated power time division downlink for a processing satellite
Inventor: LINSKY STUART T
IPC: H04J3/00
Filed: 2000-02-28
Abstract: The present invention provides a method for reducing power consumption in a satellite downlink transmitter (100).      The method includes the steps of defining a frame structure for use on a downlink, and further defining a traffic body (218, 220, 222) and an overhead body (212, 214, 216) in the frame structure (202, 204, 206). The method further determines the amount of time required to transmit the traffic body ("the traffic transmit time") and the amount of time required to transmit the overhead body ("the overhead transmit time"). Subsequently, the method activates a transmitter for the overhead transmit time to transmit the overhead body (212, 214, 216) including the synchronization information. Thus, a ground station may acquire synchronization and lock onto the downlink. The method then, however, selectively deactivates the transmitter for the traffic transmit time. The method thereby transmits the overhead body (212, 214, 216) in every frame (202, 204, 206), but may save power by not transmitting the traffic body (218, 220, 222) of the frame.
