Title: Dynamic cache replication in a network through reverse tree generation
Inventor: BUYUKKOC CAGATAY
IPC: G06F13/00
Filed: 1998-05-19
Abstract: The distribution of replica caches of information is dynamically optimized among the regions of a network, based upon the changing usage patterns. Initially, a single server in a first region stores the primary copy of information. A router in the first region receives service request messages from the plurality of users throughout network, directed to the server storing the primary copy. To determine if it is justified to deploy a replica cache, the router transmits a monitor request message to other routers in other regions of the network, requesting them to monitor all service requests in their respective regions, being directed to the primary copy in the first server. The first router then computes an optimum assignment of a replica copy of the information, for storage in at least one newly assigned server in the network. The first router transmits a replication message to the newly assigned server, to enable it to store the replica copy of the information and provide service to user terminals in a newly assigned set of regions of the network. The first router also transmits an assignment message to the other routers in the network, to enable them to redirect traffic from their respective regions to either the newly assigned server or to the first server.

Title: Spreader assembly
Inventor: TRUAN CHARLES JOSEPH
IPC: E01C19/20
Filed: 1998-05-21
Abstract: A spreader assembly for spreading materials such as, for example, salt seed or fertilizer. The spreader assembly includes a motor and transmission drive assembly which is mounted outside of the hopper to protect the motor and drive assembly from corrosive materials in the hopper. The transmission motor assembly allows a small motor with high revolutions per minute to be used and still supply the necessary torque needed to properly spread material. The spreader assembly also includes a modular mounting frame system which allows the frame to be mounted to vehicles of different sizes. The frame allows pivoting of the spreader about one axis and latching to a latching bar to secure the spreader assembly in the latched position. Rail mounting brackets are disclosed which permit mounting of the frame to the bed rails of a vehicle without the need to drill holes in to the bed rail. A rub bar is provided to prevent the spreader assembly from being pivoted when the hopper is full of material which could lead to damage to the support frame or vehicle. A unique top is provided to cover the hopper. The top employs the air flow over the top to prevent the top from being blown off of the hopper.

Patent CA-2256408-A1 (CA)
Title: Automated document classification system
Inventor: MEHRLE JOSEPH P
IPC: G06F17/30
Filed: 1997-05-16
Abstract: A program is used to scan electronically the unclassified legal document for citations.      Citations are stripped and normalized.      Utilizing a matching sofware program, the stripped and normalized citations are compared to the seed citations in the control file for matches. For each match which occurs, each new classification with which the seed citation was associated is stored in memory along with a numerical initial classification score of zero, and each previously-identified classification results in the classification score being incremented. Simple heuristic rules based upon the knowledge and experience of legal analysts are employed to increment the classification scores based on the seed citation matched. After all citations have been checked against the seed citations, all classification scores are checked against a threshold value. If the classification score for any particular classification is greater than or equal to the threshold value, then the classification key and the hierarchical document key associated with the classification are inserted into the legal document utilizing a write soft-ware program.

Title: Process and device for casting steel from an immersion nozzle
Inventor: SCHEMEIT HANS-JUERGEN
IPC: B22D41/50
Filed: 1997-05-29
Abstract: The invention relates to a process and a device for controlling the flow dispersion of a molten metal, in particular steel, which is conveyed from a melt container via a first immersion outlet part which has a polygonal, oval or circular cross-section, and an intermediate member through the second immersion outlet part which has an elongate cross-section, and flows into a stationary mould to produce slabs.  The process is characterised by the following steps: (a) the central volume flow is reduced in the intake region of the second outlet part; (b) at the same time the angle of expansion (.delta.) of the fluid jet is increased to such an extent that return flow in the lateral region of the intermediate member and the second immersion outlet part is substantially stopped; and (c) when the melt leaves the second immersion outlet part, it flows at a velocity profile with velocity vectors which are smaller in the opening centre than in the regions of the small faces. The device is characterised in that in the region of the central axis (I) of the immersion outlet, the intermediate member (31) and/or the intake (22) of the second immersion outlet part (21) is equipped in such a manner that the main flow of melt (S) leaving the first immersion outlet part is throttled.

Patent CA-2261761-A1 (CA)
Inventor: BURNISTON IAN
IPC: G01N15/06
Filed: 1997-07-23
Abstract: A component is washed with a fluid to release particulate contaminant. The particulate-containing fluid is passed through a screen (22) having a known number of apertures of identical known size. The change in pressure caused by the accumulation of particles in the screen is measured and compared with the pressure when the screen is clean. From this, a control system (54) determines the number of particles in the fluid having a size greater than the aperture size. This is related to a unit volume by measuring the volume of fluid passing through the screen (22). If the screen blocks before all the fluid is passed through the screen (22), the fluid is pulsed in forward and reverse flow to re-distribute the particles on the screen. The fluid is then back washed from the screen to a second screen (28) having a known number of apertures of identical size. The number of particles per unit volume having a size greater than the size of the apertures of the second screen is then determined. If the second screen (28) blocks, the second screen (28) is pulsed and the fluid back washed to a third screen (32) having a known number of apertures of identical size. The number of particles per unit volume having a size greater than the size of the third screen (38) is then determined. These values are displayed by the control system (54).

Inventor: GAILUS DAVID W
IPC: B41J2/16
Filed: 1995-03-17
Abstract: In the embodiments of the simplified ink jet head described in the specification, a carbon body is formed with ink passages, such as internal passages (19, 21, 25) extending through a carbon plate (26), pressure chambers (2) on one side of a carbon plate (26), flow-through passages (24) on the other side of the same plate and ink supply passages (19, 25), and a piezoelectric plate (23) is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive.  The piezoelectric plate (23) may have a conductive coating on one side which is photo-etched to produce an electrode pattern corresponding to the pattern of the pressure chambers in the carbon plate.  An orifice plate (13) may have specially profiled orifice openings (12) to assure axial projection of drops and may be affixed by a thin layer of epoxy adhesive to a carbon plate (26) having orifice passages (21) supplying ink from the pressure chambers (20) to the orifices (12).  Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate (23) and, to assure grounding of the piezoelectric plate, a conductive epoxy adhesive may be used to bond the piezoelectric plate to the carbon plate.  Moreover, since the carbon plate is porous, it can provide a communication path (76) between a vacuum source (77) and an air-permeable, ink-impermeable layer (75) on the ink passages to remove dissolved air from the ink in the passages.  In one alternative embodiment, an ink jet head assembly contains two separate carbon pressure chamber plates, a carbon manifold plate and a carbon collar to retain the carbon plates in an assembly.
