Title: Integrated method for protecting logs and green lumber from sapstain, mould, and decay
Inventor: YANG DIAN-QING
IPC: B27K3/00
Filed: 1999-05-26
Abstract: The present invention relates to an environmentally acceptable wood protection system for treating wood against sapstain, mould and decay. The wood or wood product is treated with a biocontrol agent having a high pH tolerance and an alkaline solution. Biocontrol agents that do not discolour wood may be introduced onto wood or wood products to prevent sapstain and mould. The biocontrol agent grows on the wood surface and protects the wood against attack by stain or decay fungi. The application of an alkaline solution containing a biocontrol agent having a high pH tolerance to the wood product is very effective in controlling stain or decay fungi. The alkaline solution raises the pH of the wood to a level which impedes growth of other wood-inhabiting fungi but does not inhibit colonisation of the wood by the biocontrol agent.

Title: Carbon monoxide automatic furnace shutdown
Inventor: NICHOLSON LEROY E
IPC: F23N5/24
Filed: 1999-06-15
Abstract: An automatic safety system for a fluid fuel air heating furnace. The safety system utilizes a double-sided carbon monoxide sensor for detecting unsafe levels of carbon monoxide interiorly and exteriorly of the furnace's heated air duct and a single-sided carbon monoxide sensor for detecting unsafe levels of carbon monoxide interiorly of the furnace's flue pipe.      The sensors employ carbon monoxide detector chips which are electrically conductive in normal conditions, but become non-conductive when exposed to levels of carbon monoxide that are deemed unsafe for humans. The sensors are incorporated in an electrical circuit for energizing a solenoid valve which valve, when energized, opens to permit fuel flow to the furnace. Detection of unsafe levels of carbon monoxide will result in the sensors becoming non-conductive, thereby causing the solenoid valve to become de-energized and to close thereby preventing fuel flow to the furnace.

Title: Method to sequence changes for ip network configuration
Inventor: MAZUMDAR SUBRATA
IPC: H04L12/56
Filed: 2000-04-11
Abstract: Updating of routers is achieved by insuring that the scheduling of router updates is such that a zone of turbulence that occurs where the updating takes place does not prevent reaching any router that may be in need of updating.     For IP routers that have a task scheduling capability, this is achieved by estimating the time for communicating update information to all routers that need to be updated, adding that estimate to time of day, and transmitting the update specifications. In arrangements where routers do not have a task scheduling capability, updating is sequenced. One embodiment creates a set of traceroute trees that cover the nodes to be updated, and leaf nodes of the trees are taken up at random, placed in an ordered list and deleted from the trees. Another embodiment is more tree centric, in that once a starting node is identified (and its associated tree), all of its nodes are considered before progressing to another tree. A third embodiment takes advantage of the fact that is a node to be updated in not reachable when its updating is to be done, a second try that follows a delay is likely to succeed.

Title: Dynamic web page caching system and method
Inventor: CORCORAN MICHAEL
IPC: G06F17/30
Filed: 2000-07-11
Abstract: A system for caching dynamic web pages has caching software which intercepts requests for resources from a web server. The caching software determines whether the resource might be cached and, if so, whether it has been cached. If the requested resource has been cached then the caching software redirects the request to the cached resource. If not, the caching software passes the request to the server and waits for the server to forward the resource to the user which requested the resource. The caching software makes and caches a copy of the resource. In preferred embodiments the caching software plugs into the server software. The system can maintain accurate logs of requests for resources. Caching can be dependent upon the query string, header information and/or cookie information.      The system can be used to provide increased performance in serving dynamic data.
