Patent CA-2283308-A1 (CA)
Title: Conveyor having a cushioned belt and high speed discharge capabilities
Inventor: BONNET HENRI
IPC: B65G47/94
Filed: 1998-04-16
Abstract: An automated conveyor sortation and item discharge system for conveying and discharging packages at high speeds. A conveyor assembly includes an elongate crowned conveyor belt (20), which conveys parcels in a longitudinal direction defined across slider beds (18) and across discharge stations. The parcels can take three different routes once they reach the discharge stations. They may be allowed to pass the discharge stations and continue to be conveyed by the crowned conveyor belt, or they can be selectively discharged off of the crowned conveyor belt and into discharge chutes located to either side of the substantially straight path of the crowned conveyor belt. Each of the discharge stations includes a selectively indexable fork member supporting a group of idling rollers. The parcels have sliding contact with the slider beds and "rolling contact" with the idler rollers. When a package is in the desired position, the fork member can be indexed to cause some of the rollers to move upwardly and inwardly. This causes the package to tilt about the top of the crowned conveyor belt until the package contacts a withdrawal roller opposing the conveyor belt from the raised rollers. The withdrawal roller draws the package into one of two chutes for sorting purposes.

Patent CA-2288488-A1 (CA)
Title: Method and apparatus for transparently directing requests for web objects to proxy caches
Inventor: COHEN ARIEL
IPC: H04L29/08
Filed: 1999-11-03
Abstract: In order to transparently redirect an HTTP connection request that is directed to an origin server (107) to a proxy cache (110-1), a proxy redirector (104) translates the destination address of packets directed to the origin server to the address of the proxy. During a handshaking procedure, a TCP connection is transparently established between the client (110-1) and the proxy cache. When the client transmits a GET request to what it thinks is the origin server, which request specifies the complete address of an object at that origin server that it wants a copy of, the proxy redirector modifies the complete address specified in that GET request before it is sent to the proxy cache. Specifically, the IP address of the origin server found in the destination field in the IP header of the one or more packets from the client containing the GET request is added by the proxy redirector as a prefix to the complete URL in the GET request to form an absolute URL. The proxy cache determines from that absolute URL whether it has the requested object stored in its cache. If it does, it sends the object back to the proxy redirector, which masquerades those packets as coming from the origin server by translating their destination address to the address of the client and their source address to that of the origin server. If the proxy does not have the requested object, a separate TCP connection is established between the proxy and the origin server from where the object is retrieved and then forwarded over the TCP connection between the client and the proxy. In order to account for the additional number of bytes in the GET request, an acknowledgement sequence number in packets returned from the proxy that logically follow receipt of the GET request are decremented by that number by the proxy redirector before being forwarded to the client. Similarly, a sequence number in packets transmitted by the client subsequent to the GET request are incremented by that number before being forwarded by the proxy redirector to the proxy cache.

Patent CA-2291535-A1 (CA)
Title: Method and apparatus for drilling boreholes in earth formations (drilling liner systems)
Inventor: MAKOHL FRIEDHELM
IPC: E21B7/06
Filed: 1999-12-03
Abstract: A drilling liner having a core bit at its bottom end is carried along with a pilot bit on an inner bottom hole assembly driven by a downhole mud motor. In one embodiment, the motor is powered by mud carried by an inner string. Alternatively, the inner string may be omitted and the flow of mud through the liner powers the motor: this requires a locking tool for locking the motor assembly to the outer assembly. Once an abnormally (high or low) pressured zone has been traversed, the liner is set as a casing, the inner assembly is pulled out, and drilling may be resumed using a conventional tool. Directional drilling is accomplished by having an MWD device for providing directional information and having directional devices on the inner and outer assembly.  These include retractable steering pads. Expandable bits, under-reamers and jetting nozzles may also be used in the drilling process. One embodiment of the invention has a bottom thruster between the mud motor and the drill bits that makes it possible to continue drilling for a limited distance even if the upper portion of the casing is stuck.
