Patent CA-2303119-A1 (CA)
Inventor: SANKARAN SUBBIAH
IPC: B65H19/28
Filed: 1998-07-13
Abstract: Apparatus and a process for the high-speed coiling of an aluminum strip. The high speed coiling can be accomplished throughout a continuous casting process without slowing the coiling as the present invention enables the transfer of the moving strip from one coil to an empty mandrel without slowing the line speed. Since line speeds can be approximately 3600 feet per minute, this represents an advance in process technology. Generally, the transfer of the moving strip is accomplished using a very high speed knife (28), and a belt wrapper (24). The moving strip is accumulated on one mandrel (2) to form a coil, the coil is moved away from the knife and a second mandrel (4) is brought into position. The knife is positioned at the moving aluminum strip and accelerated to cut the strip and deflect it to a tucking roll with a moving belt. The moving strip is forced around the second mandrel and starts to wind to form a coil. The completed coil is removed and the process is repeated.

IPC: B21B31/10
Filed: 2000-04-26
Abstract: The invention refers to a straightener for rolled ferrous products, of the type in which a framework (11) comprises a pair of opposed shoulders (12, 13) which support two sets of rolls, a top set (14) and a bottom set (15), which define between them a straightening path for straightening said rolled products. According to the invention, said opposed shoulders (12, 13) may be translated horizontally between a closed, operative, position of containment and support of said rolls (14, 15), and an open, non-operative, position, in which said sets of rolls (14, 15) may be removed for replacement with other sets of different rolls.      Moreover provided are supporting and transporting means, which are independent of the aforesaid framework (11), for supporting said sets of rolls (14, 15) in said open, non-operative, position of the shoulders (12, 13).
Patent CA-2307008-A1 (CA)
Title: Method and system for a session allocation manager ("sam")
Inventor: FOULKES JONATHAN
IPC: H04L29/08
Filed: 2000-04-28
Abstract: A Session Allocation Manager ("SAM") manages multiple client connections to a limited number of host terminal sessions. The SAM also minimizes the latency involved in creating and terminating a host session. The SAM may reside on a server in the communication path between the client and the host session.  Host data objects may use the SAM to associate a client connection to a host session. The SAM monitors the session activity and enforces inactivity timeouts. The SAM  also attempts to reestablish a host session when it fails. In an environment having only a limited number of available terminal sessions, the SAM may control the session by creating a session window. A connection mechanism directed by the client may then request a session window from the SAM. If multiple clients ask for the same connection mechanism, the SAM may dedicate a particular session window to a particular type of connection mechanism.

Title: Wireless ceiling communication bus system
Inventor: FRECSKA SANDOR A
IPC: H04L12/28
Filed: 2000-08-09
Abstract: A wireless communication bus system for transmitting electromagnetic signals to and from devices located in defined areas of a managed building space partitioned into a plurality of rooms is disclosed. A controller device located above a ceiling grid system generates electromagnetic signals to control operation of the devices through a plurality of wireless transmitter/receiver modules, also located above the ceiling grid. The wireless transmitter/receiver devices together form a wireless communication bus and relay electromagnetic control signals between the controller and the controlled devices. Wireless repeater transmitter/receiver modules can also be added to the wireless communication bus to relay electromagnetic signals between other wireless transmitter/receiver devices that form part of the wireless bus. Each wireless transmitter/receiver module has a unique address that can be selected by the controller in order to relay an electromagnetic signal to a device that is closest to the wireless transmitter/receiver module. The wireless transmitter/receiver modules operate on different frequencies set by the controller to enable direct communication with targeted devices.

Title: Container transfer terminal system and method
Inventor: ARNTZEN JOHN
IPC: E02B3/20
Filed: 1999-03-08
Abstract: A terminal and system for the automatic computerized unloading of containerized cargo from container ships to trucks, railroad cars, other ships or storage. The terminal system (10) is equipped to store or transfer unloaded cargo automatically by using independent container transfer vehicles (26).  The cargo ships (20) are moored between quays (22) of a terminal building constructed in or adjacent to a waterway. Independent container transfer vehicles (26) on an overhead transverse beam (28) system lift a container (18) up and away from a ship and transfer it to the elevated ground rail (72) system without changing the container orientation, and then shuttle on elevated ground conveyance rails to other areas of the terminal to distribute the container to the pertinent transportation system (railcar, truck, another ship) or to storage (40). Containers can also be unloaded from trucks and railroad cars and transported to a berthed ship utilizing the same transportation system. Remotely controlled docking modules (199) may be used to guide an incoming ship into the quay and to assist in engaging the ship's hull onto a bow mooring assembly (144). Side fenders (162) positioned in the quay moor the ship and maintain its position within the dock during cargo transfers. A rapid fueling system refuels the ships. The terminal can be located on land or offshore in any navigable waterway with either an access tunnel or a causeway for truck and rail access from land.

IPC: H04L12/42
Filed: 2000-11-03
Abstract: In the bus switch system of the invention, with the adapter, the first input and first output registers in cascade connection on the data transferring bus of bus switch compose a shift register.      Also, with the bridge, the second input and second output registers in cascade connection on the first data transferring bus compose a shift register. This allows data to be transferred to the adjacent adapter at one clock cycle, thereby the clock rate in data transfer is made faster. Also, the data transfer on the first and second data transferring buses is conducted in one direction and the input/output control is optimally conducted by the first and second control means. Thereby, the switch control in data transfer is made easier.

The proposed method and system feature transporting such a pre-assembly through a processing zone, and, within that zone, creating within the pre-assembly both cyclic compression and cyclic heating compression is effected principally utilizing distributed pairs of opposing pinch rolls which act on transported material either through independent platens, or through surface materials which become incorporated in a final pressed-wood product. Cyclic heating is effected through use of microwave wave-guides interleaved effectively with the pressure-applying pinch rolls.

Title: Vector construction by host cell-mediated recombination
Inventor: PERKINS EDWARDS L
IPC: C12N15/10
Filed: 1999-06-17
Abstract: Described are methods and materials which enable rapid, efficient, and scalable cloning of one or more specific target nucleic acid molecules into suitable expression vectors without the need for performing an in vitro ligation step. The invention takes advantage of gap repair mechanisms to produce the desired expression vector(s) in host cells capable of mediating intermolecular homologous recombination. Specific target nucleic acids are cloned by producing expression vector intermediates containing two sequence-specific recombination regions, each of which is substantially homologous to a specific recombination sequence flanking the desired target nucleic acid, through a nucleic acid amplification process using primers which each include a different 5' sequence-specific recombination sequence which lacks complementarity with the base vector and a different 3' priming portion substantially complementary to a primer binding site in the base vector.
