Title: Method of inactivating microorganisms in a fluid using ultraviolet radiation
Inventor: KAISER KLAUS
IPC: A23L2/42
Filed: 2001-11-12
Abstract: A method of inactivating microorganisms such as viruses within a fluid such as a biological fluid is disclosed. The method includes the steps of providing a UV reactor, which may take the form of an elongated generally annular reaction chamber surrounding at least one elongated UV lamp, moving the fluid within the reaction chamber in a primary flow directed along the length of the UV lamp, and inducing a circulating secondary flow within the fluid with the secondary flow being superimposed on the primary flow. As the fluid moves through the reaction chamber in the primary flow, it is circulated repeatedly toward and away from the UV lamp in the circulating secondary flow to provide uniform and controllable exposure of the entire volume of fluid to ultraviolet radiation. Microorganisms such as viruses are thus inactivated while desirable components in the fluid, such as proteins, are preserved without the use of a free radical scavenger.

Patent CA-2442190-A1 (CA)
Inventor: WILSON DOUGLAS KENT
IPC: G06F16/955
Filed: 2003-09-24
Abstract: The invention dynamically produces alternate referrer pages substantial ly similar to pages previously viewed, through a web browser, by a visitor who linked to a target web page via a link on the previously viewed pages. When the browser links to the target page, a referrer URL is obtained for the referrer page from which the browser loaded the target page. The referrer URL is stored in a queue. The queue is inspected regularly. If the queue contains an unexamined entry, a request for that entry's referrer URL is executed to obtain the alternate referrer pages. The IP address of the computer running the browser is used to derive a country code corresponding to the IP address. The referrer URL request can be issued through a computer in a geographic region corresponding to the country code so that geographic biasing of the previously viewed pages will be reflected in the alternate pages.</SDOAB >

Title: Welding shielding gas saver device
Inventor: UTTRACHI GERALD DANIEL
IPC: B23K9/32
Filed: 2004-01-21
Abstract: This device significantly reduces major reasons for shielding gas waste primarily in metal inert gas welding. Excess shielding gas stored at the end of each weld in the shielding gas delivery hose connecting the gas source to the welding machine creates a shielding gas flow-surge at the next weld start. This gas flow-surge creates shielding gas waste and can cause poor weld start performance. Other methods employed over the years to reduce shielding gas waste have been either complex, leaked, were not sufficiently robust for the environment, provided only partial solutions or did not provide shielding gas savings for welds longer than about three seconds. This device includes a delivery hose connecting the shielding gas supply to the welding machine, which has a small internal volume and a gas surge-restricting orifice at the gas solenoid end of the hose.

Title: Method and apparatus for finding differences between two computer files efficiently in linear time and for using these differences to update computer files
Inventor: JONES KERRY N
IPC: G06F8/658
Filed: 2004-05-05
Abstract: A method of updating a computer file from an old file into a new file comprises blocking the new file and the old file into fixed-sine blocks, maintaining a window (collection of contiguous blocks) for each file on which lookup preprocessing has been performed, and performing match processing on each new file block in turn (comparing agains t both the old and new windows) using a key-sampling technique combined with approximate matching. For each new file block, the match information is then optimized for coding efficienc y and encoded onto a patch file that describes an algorithm for converting the old file into the new file. The patch file application method and apparatus then performs the algorithm described in th e patch file, The method uses a fixed amount of random-access memory regardless of the sizes o f the two files and uses a temporary mass storage. In addition, the method has a running tim e roughly proportional to the size of the new file and allows the use of parallel processing to reduce the time required. The system and method produce patch files which are smaller than prior systems and methods, and allow the operator of the apparatus to perform an efficiency/effectiveness trade-off.
