Patent CA-2459471-A1 (CA)
Title: Method of continuously casting electrical steel strip with controlled spray cooling
Inventor: WILLIAMS ROBERT S
IPC: B22D11/06
Filed: 2002-09-13
Abstract: A method for continuously casting grain oriented electrical steel is disclosed. This method utilizes a controlled rapid cooling step, such as one using a water spray, to control the grain orientation in the finished product.  The product formed not only has the appropriate grain orientation but also has good physical properties, for example, minimized cracking. In this process, after a continuously cast electrical steel strip is formed, the strip undergoes an initial secondary cooling to from about 1150 to about 1250~C, and finally undergoes a rapid secondary cooling (for example, by water spray) at a rate of from about 65~C/second to about 150~C/second to a temperature of no greater than about 950~C.

Inventor: YOWARD NICHOLAS LLOYD
IPC: B01D29/33
Filed: 2002-12-10
Abstract: A filter assembly comprises a filter (10) defining path for fluid passing to or from the filter (10). An adaptor (11) is connected to the filter (10) and provides a continuation of the path. The adaptor (11) is for mounting the filter (10) on a mounting plate (12) and carries one or more sealing rings (30, 37) that are engageable with the mounting plate (12). The adaptor (11) is made from a plastics material and one surface of the adaptor (11) is reinforced by contact with an annular reinforcing member (31) which may be o f metal, particularly steel. This allows the flow path provided by the adaptor (11) to be maximized.

Title: Bag having reclosable seal and associated methods
Inventor: SOLOMON GEORGE
IPC: B65D33/20
Filed: 2004-03-02
Abstract: A bag (20) having a reclosable sealer (22) and methods of forming and using the same are provided. The bag (20), for example, can include a tube body having a plurality of laminated layers. A reclosable sealer (22) can be attached to a first wall (21) of the tube body. When the bag (20) is in an open bag position, a first portion (35) of the reclosable sealer (22) is separated from a second portion (45) of the reclosable sealer (22). When the reclosable sealer (22) is in the closed seal position, the first portion (35) of the reclosable sealer (22) contacts the second portion (45) of the reclosable sealer (22) forming a seal to thereby allow the bag (20) to be readily opened and closed. Peripheral portions (49) of the bag (20) can remain unsealed after initial opening when the reclosable sealer (22) is in the closed seal position to indicate that initial opening has occurred and the tampering with the bag (20) may have occurred.

Title: Automatic refill of a virtual postage meter
Inventor: SARIN MANU
IPC: G07B17/00
Filed: 2002-09-11
Abstract: A method and system for dynamically optimizing the amount of an automatic refill of a shared virtual postage meter is disclosed. A desired time between refills is predetermined based on the capacity of the system to perform refills, the time required to process a refill, and the impact of performing a refill on the overall performance of the system. A refill amount candidate is then determined based on the predetermined desired time between refills, the elapsed time since the last refill and the amount of the last refill. The determined refill amount candidate is then further validated to insure that it falls within a range of a predetermined minimum and maximum refill amounts.  One validated, the refill amount candidate is the optimal refill amount, and the shared virtual postage meter is refilled accordingly.

Title: Skin lesion exciser and skin-closure device therefor
Inventor: BANBURY MICHAEL KENNETH
IPC: A61B17/08
Filed: 2002-09-30
Abstract: A skin lesion exciser including a moving blade, wherein excision of a skin lesion placed in proximity to the blade is effected by movement of the blade against the skin, a moving engagement portion, wherein the blade and the engagement portion have coincident movement, and a skin-closure device having an open condition prior to excision of the skin lesion, and a closed conditions in which the device holds the skin closed after excision of the skin lesion. The device is in engagement with the engagement portion during movement of the blade, and the device is moved from its open to its closed condition in response to movement of the engagement portion. The excision of the skin lesion and the closure of the skin are substantially simultaneous.

Title: Steering damper device
Inventor: GOGO KAZUHIKO
IPC: F16F9/06
Filed: 2004-08-09
Abstract: To provide a steering damper device having a desired damping characteristic in which a gradually increasing damping force is generated according to the turned angle when a handle is turned, and the damping force is not generated when the handle is returned using an inexpensive cylindrical damper of a simple structure. A cylindrical damper is disposed between a head pipe for rotatably supporting a steering stem and a fork bridge of a front fork so as to be the shortest when the handle is at a neutral position. The cylindrical damper is connected to the head pipe and the fork bridge via spherical joints. The cylindrical damper generates the damping force when being expanded. Since the cylindrical damper is expanded when the handle is turned either directions, left or right, a damping force is generated.

Title: Thermoplastic fluoropolymer-coated medical devices
Inventor: CLEEK ROBERT L
IPC: A61L27/34
Filed: 2003-08-05
Abstract: A medical device provided with at least a partial surface coating of a thermoplastic copolymer of tetrafluoroethylene and perfluoroalkylvinylether that is free of cross-linking monomers and curing agents. The fluoropolymer coating is preferably an amorphous thermoplastic, is highly inert and biocompatible, has elastomeric characteristics that provide desirable mechanical properties such as good flexibility and durability. These characteristics allow the coating to be considered "functionally transparent "  because it withstands mechanical deformations required for the assembly, deployment, expansion, and placement of medical devices, without any adverse effect on the mechanical and biological functionality of the coated device.  Further, its inertness, derived from the perfluorocarbon structure, contributes to its functionally transparent nature. The coating can be provided with various liquid or solid additives, can be loaded with large quantities of additives including a wide range of therapeutic agents, and has excellent drug elution characteristics when elutable additives are used. The desirable mechanical characteristics are surprising given the absence of cross-linking monomers and curing agents that would otherwise render such materials inadequately biocompatible. The perfluoroalkylvinylether may be perfluoromethylvinylether, perfluoroethylvinylether or perfluoropropylvinylether.
