Patent CA-2288297-A1 (CA)
Title: Method of and apparatus for determining authenticity of coins
Inventor: FURUYA YONEZO
IPC: G07D5/08
Filed: 1999-02-25
Abstract: A method of and apparatus for determining authenticity of coins based on difference in surface irregularity pattern of coins. A coin passage is inclined at a predetermined angle, and an exciting coil is arranged near one side wall of the coin passage such that the two magnetic poles of the exciting coil face the coin passage. Two receiving coils having substantially identical characteristics are arranged near the same passage wall such that they are electromagnetically coupled with the exciting coil. The exciting coil is excited at a predetermined frequency, and an influence of a demagnetizing field caused by eddy current induced on the surface of a coin is detected by the receiving coils. The level of the demagnetizing field varies depending on difference in surface irregularity pattern of coins, and thus authenticity of coins can be determined based on the difference in surface irregularity pattern. This can be attained with a simple, inexpensive arrangement.      Even those coins which are almost identical in material, outside diameter and thickness can be discriminated from one another based on the difference in surface irregularity pattern.
Patent CA-2290657-A1 (CA)
Inventor: BRUIN JAN ANTHONIE
IPC: A61K35/407
Filed: 1998-05-25
Abstract: The invention relates to the field of transplantation, specifically to the field of transplantation of isolated cells. The invention provides a method to allow cell transplantation as a method to replace organ transplantation. Anti-integrin (poly)peptides significantly block attachment of cells to both vessel walls and tissue in an in vitro binding assay. Blocking of integrins by incubation with blocking (poly)peptides significantly decreases the number of cellular aggregates after in vivo cell transplantation, and has a significant increasing effect on cellular homing in the recipient tissue. Blocking of integrin strongly improves transplanted cell survival in the recipient tissue after transplantation.
Patent CA-2292410-A1 (CA)
Inventor: BLUM JOHN N
IPC: B41J2/18
Filed: 1999-12-10
Abstract: In a continuous ink jet printing system, the printhead is pressurized by the flow of filtered air supplied by the printhead docking station to which it is attached or docked. The printhead docking station has at least one fan for moving air and for transferring the air from the printhead docking station into the printhead. The printhead receives air for the printhead docking station, and directs the air flow to the region around the jet array. The directing of air flow to the region around the jet array can also include reduction of air leakage from the printhead in regions which are away from the jet array region, such as by the use of a seamless cover, and eyelid sealing. Plenum located in at least the printhead and/or printhead docking station serve to distribute the air across the width of the printhead. Filter media located in at least the printhead and/or printhead docking station are used to clean the air supplied to the printhead by the printhead docking station. In this way, filtered air is supplied to the ink jet printhead by the printhead docking station to which it is attached. The use of a one piece printhead cover and seals around the movable eyelid minimize air leakage from the printhead, ensuring the needed air flow in the critical region around the jets.

Title: Mapping arbitrary signals into sonet
Inventor: ROBERTS KIM B
IPC: H04J3/16
Filed: 2000-05-18
Abstract: A synchronizer/de-synchronizer maps continuous format signals of an arbitrary rate into frames of pre-selected single common rate, such as SONET frames, with no bits changed and very little jitter or wander added. In this way, the continuous format signal may be carried transparently as a tributary of a SONET network. Each frame comprises a definite number of fixed stuff bits, including transport overhead bits and reminder fixed stuff bits. A frame also comprises an adjustable number of adaptive stuff bits, resulting from the phase difference between the arbitrary rate and the common rate. A mapping function is performed in a tributary unit shelf of a SONET transport shelf, and the reverse mapping function is performed in a similar way at the far end of a SONET connection. The stuff bits are spread uniformly within the frame.

Filed: 2000-07-19
Abstract: During on-line product design and ordering, a user creates a visualized set of selected customized aspects, resulting in a series of instructions on how to manufacture the customized item. These instructions for the sourcing of inputs, manufacturing instructions, shipping, packing, customs, and billing of a customized order are stored in a single XML  file that has been translated into all of the languages of the relevant locales. The system then generates all of the required documentation for each step in the supply chain. Consequently, the inputs and manufacturing may be performed in a locale that does not use the same language as the originating locale of the order, since the bill of materials is multi-lingual.

Abstract: A housing system for aquatic animals has a shelf-like rack holding tiers of individual tanks or aquariums (aquaria), each removably suspended from structural members that engage flanges of the tanks. The tanks are tilted inwardly of the rack and have covers with fittings on the higher or outer side, that intercept flow between a supply and a drain to inlet water when the tank is in the rac k and to recycle the water at any tank position that is unoccupied. The inside bottom  of each tank is contoured, for example with a longitudinal trough, so sediment collects at a low spot on the lower or inner side, where a drain inlet is placed to provide a drainage outlet that opens at a velocity increasing restriction at  which sediment is entrained. The drain has a spring biased valve that opens the drain only when the tank is fully inserted in the rack. Water supply, water drain and air supply conduits are integrated using an extrusion or multiple passage condui t for air supply, water supply and water return at the interception point of the tank water inlet. The housing system is apt for zebrafish for laboratory experimentatio n.

Abstract: A carbon composite structure, for example, an automotive engine piston, is made by preparing a matrix comprised essentially of a mixture of non crystalline particulate soluble in an organic solvent and a binder that has a liquid phase. The non crystalline particulate also contains residual carbon hydrogen bonding. An uncured structured is formed by combining the matrix mixture, for example, carbon fibers such as graphite dispersed in the mixture and/or graphite cloth imbedded in the mixture. The uncured structure is cured by pyrolyzing it in an inert atmosphere such as argon. Advantagesoulsy, the graphite reinforcement material is whiskered prior to combining it with the matrix mixture by a method involving passing a gaseous metal suboxide over the graphite surface.
