Patent CA-2408948-A1 (CA)
Title: Catheter device
Inventor: BYRNE PHILLIP OWEN
IPC: A61M25/16
Filed: 2001-05-31

Patent CA-2409520-A1 (CA)
Inventor: JACOBS ROSS A
IPC: C21C5/46
Filed: 2000-05-17
Abstract: A method and an apparatus for enhanced metallurgical processing of molten metal includes an enclosable ladle chamber (23) for reducing the escape of heat during transport of the ladle from a manufacturing vessel such as a furnace (13) to an intermediate processing (15) or refining station or during processing or transport to a receptacle vessel such as a tundish (17). The method comprises introducing a refractory body into the ladle chamber (23), the body having an adjusted specific gravity having a reduced steel ballast to refractory material ratio that is less than required for a specific gravity required to buoyantly support the body in the molten metal. Preferably, the ratio provides a specific gravity greater than the specific gravity required to buoyantly support the body entirely in the slag layer. The method includes enclosing the ladle (22) for example, with a lid (90) and maintaining said refractory body in said ladle until substantially termination of the discharge of the molten metal from the vessel. Preferably, the method also includes intermediate refining such as introducing a balancing composition to the ladle before enclosing. The ratio of steel ballast and refractory material used to achieve the preferred specific gravity may also be adjusted in conjunction with other temperature-resistant or corrosion-resistant changes to the refractory body. For example, high temperature alumina may be used as a refractory material in a higher degree than in previously known bodies, a high temperature cement may be used to join the refractory material and ballast components, and a non-wetting agent made of carbonaceous or siliceous material may reduce deterioration of the body during the extended period of steel and slag contact in the ladle.

Pores are provided in the anode body so as to take up the corrosion products. The reinforcing layer can be provided in the actual anode body as a closed surface surrounding the anode material inside or may be provided in the concrete as a layer on top of the anode in an array form at or near the outer surface of the concrete.

Abstract: A hand held device (1) for recording scores of a golf game played by one or more players comprises a VDU (3) which selectively displays reference fairways (30) graphically which permits a player to enter the position of the location of a ball after each shot on the VDU (3) by positioning a cursor at a position (41) on the green (31) or the reference fairway (30) displayed on the VDU (3), which substantially corresponds to the position of the ball on the fairway or green being played. The position of the ball after each shot until the ball is holed is entered on the screen through the cursor. A microprocessor (2) reads the position of the cursor and stores a graphical representation of the progress (37) of the ball along the screen to the hole (29). The microprocessor (2) stores the graphical representation of the reference fairway (30) with the positions (41) of the ball entered through the cursor in a RAM (5) and computes the number of shots to the hole (29). This is repeated for each hole played in a game of golf and a score card for each player is displayed on the VDU(3) at the end of the game. The device (1) may be used by number of pplayers playing a game of golf, and respective score cards are generated for each player and displayed on the VDU. Graphical representations of each player's performance on each fairway can be reviewed after the game.
