Title: Load balancing across the processors of a server computer
Inventor: MARTIN SEAN JAMES
IPC: G06F17/30
Filed: 1996-12-04
Abstract: The present invention relates to a server computer connectable to a network and having a plurality of processors (20, 30, 40) arranged to provide a service to one or more client computers connected to the network. The service involves the provision of blocks of information to a client computer (50), and the processors have access to a data storage (120) in which data for the blocks of information is stored.      According to preferred embodiments of the invention, each processor in the server has block retrieval means (80), employed in response to a request from a client computer (50) for a particular block of information from that processor, to retrieve data from the data storage (120) in order to construct a file representing the requested block of information, the file including references to subsequent blocks of information requestable by the client (50). Additionally load determining means (100) is provided of periodically determining activity data for the processor for inclusion in a load distribution record maintained for all of the processors of the server. Decision means (90) is then used which, for each reference to a subsequent block of information in the file constructed by the block retrieval means (80), is arranged to determine, based on the load distribution record, which processor should service a request from the client computer (50) for that subsequent block of information, and include an address for that processor in the file constructed by the block retrieval means (80). Once the decision means has completed this process, the file is then sent to the client computer (50). In preferred embodiments, the service being provided is the World Wide Web (WWW) service, and the technique is employed on a parallel Web server providing Web pages to clients over the Internet. By employing the technique of the invention, more effective load balancing across the processors of the Web server is possible, thereby enabling problems such as "toasting" of a particular processor to be averted.

Title: Method of converting rendered triglyceride oil from marine sources into bland, stable food oil
Inventor: MAG TED
IPC: A23L33/115
Filed: 1999-01-29
Abstract: Triglyceride oil derived from marine sources, mammalian and fish, is treated with a silica at relatively low temperature under vacuum and is then further treated with a bleaching clay under vacuum and at higher temperature. The silica and the bleaching clay are then separated from the oil. The oil treated by this method is essentially free of proteinaceous materials, phosphatides and mucilage, pro-oxidant metals and very low in colored compounds, and is suitable for deodorizing. The deodorized oil is completely bland, unchanged in the concentration of the long-chain highly unsaturated fatty acids (EPA, DPA and DHA), very low in color, peroxides and secondary oxidation products, free of pesticides and has very good flavor stability.      The method avoids the use of any chemicals, such as in the acid and base treatments required in conventional degumming and alkali refining of oils of marine origin. This avoids the formation of artifacts in the oil and trace contamination with chemicals. It also reduces the number of process steps required to produce deodorized food oil from marine sources, which is advantageous in respect to oil quality, process losses and processing costs. The method is especially environmentally advantageous, since it avoids the need for soapstock and waste wager processing entirely. Refined oil produced by the method is useful as a nutritional supplement and in methods of therapy or medical treatment.
