Patent CA-2324945-C (CA)
Inventor: KATZ JOSEPH
IPC: B24C5/04
Filed: 1998-03-21
Granted: 2004-09-07
Abstract: A high speed fluid jet nozzle made at least in part of a porous material and configured so that the porous part of the nozzle is surrounded at least in pan by a reservoir containing a lubricant fluid. As a cutting fluid passes through the nozzle, lubricant from the reservoir is drawn through the porous material and lubricates the surfaces of the nozzle exposed to the fluid jet. The invention not only resolves the main difficulties of the prior an relating to nozzle wear, it expands the use and applications of high speed fluid jet cutters. By reducing wear of a jet nozzle, it is possible to increase the jet speed and reduce the nozzle diameter even further than the prior art, allowing much higher precision, deeper cutting, and usage on difficult to cut material such as ceramics. The invention thus provides a reliable but yet very simple method for preventing nozzle wear.
Patent CA-2325090-C (CA)
Inventor: TEZUKA HIROSHI
IPC: H04B10/00

Granted: 2008-02-05
Abstract: An optical transmission system allowing precise error rate evaluations is disclosed. A transmitting element performs error-correction coding and transmits an error-correction coded transmission signal. A receiving element decodes the reception signal to produce decoding failure information when a decoding failure occurs, and calculates a number of errors after the error correction decoding based on the decoding failure information. The number of errors is determined based on an error-correcting capability of the error correcting code when the calculated parity information does not perfectly match the extracted parity information.

Title: Coil car with internal walkway
Inventor: AL-KAABI MOHAMMED
IPC: B61D17/10
Filed: 2000-12-15
Granted: 2008-09-09
Abstract: A coil car has a pair of deep side sills and a trough structure mounted to, and suspended between, the deep side sills for carrying coils. The side sills extend between the rail car trucks and act as a pair of deep side beams for carryin g vertical loads. The deep side sills are arranged to extend above and below the center sill of the coil car to give vertical stiffness to the coil car. The top chord membe rs of the side sills are outwardly splayed relative to the bottom chord members of the side sills. Cross-bearers extend outwardly and away from the center sill to attach to th e side sills. The trough structure has three parallel, longitudinally extending troughs - a central trough lying between two laterally outboard outer troughs. Each trou gh is shaped to cradle steel coils, or other similar loads, between its inwardly a nd downwardly sloping shoulder plates. The shoulder plates are lined with cushioning to buffer coils during loading or travel. The outboard troughs are mounted abov e longitudinally extending stringers and are carried at a greater height relative to top of rail than the central trough. The car has coil stops to discourage longitudinal shifting of loaded coils. The coil stops have rollers to facilitate repositioning during loading, and a mid-span step and handgrabs to facilitate climbing over the coil stop by personnel walking along the trough structure.

Abstract: A method and mechanism are provided for creating. maintaining, and using a hierarchical index to efficiently access information in a relational system based on pathnames, thus emulating a hierarchically organized system. Each item that has any children in the emulated hierarchical system has an index entry in the index.  The index entries in the index are linked together in a way that reflects the hierarchical relationship between the items associated with the index entries. Pathname resolution is performed by following direct links between the index entries associated with the its in a pathname, according to the sequence of the filenames within the pathname. By using an index whose index entries are linked in this manner, the process of accessing the items based on their pathnames is significantly accelerated, and the number of disk accesses performed during that process is significantly reduced.

IPC: B65D30/08
Filed: 2002-02-15
Granted: 2010-05-04
Abstract: A bag having a built-in closure tab is defined. The closure tab is formed from the outer layer of the laminate which makes up the bag. When a user of the bag wishes to close the bag, the user folds or rolls the sides of the bag together down the side of the bag having the tab. The tab is partially separated from the rest of the outer layer of the laminate. A pressure sensitive adhesive disposed on the interior surface of the tab is used to affix the tab to the rolled down portion of the bag, preventing unwanted opening of the bag. The tab may be affixed and removed from the rolled down portion a number of times, thereby allowing the user to open and reseal the bag as many times as desired.
