Abstract: The present invention relates to an apparatus for supplying bottom-blown gas through a porous plug in ladle for molten metal refining. A gas supply pipe 3 is connected to a bottom-blowing porous plug 2 attached at the bottom of a ladle 1. An accumulator tank 11a, which is provided in parallel with the gas supply pipe 3. The bottom-blown gas is accumulated into the accumulator tank 11a, and blown into the ladle 1 to agitate the molten metal through the gas supply pipe 3 during refining. After the refining is finished, the switching valve 4 of the gas supply pipe 3 is closed, the switching valve 4a of the accumulator tank 11a is opened and the bottom blowing of a small amount of gas is supplied, and the blowing apparatus 10 is separated from the gas supply source 6 by removing the joint 5. The bottom blowing of a small amount of gas for a long period of time prevents the molten metal from permeating into the ventilating pores of the bottom blowing porous plug after the refining, so that the solidification of molten metal in the ventilating pores of porous plug and the clogging of the pores can be avoided. Thereby, the repeated use of porous plug is made possible without the replacement of the porous plug.

Title: Catheter centering device
Inventor: STINSON JONATHAN SWIFT
IPC: A61F2/958
Filed: 1998-03-19
Granted: 2002-12-03
Abstract: A medical device (10) for treating a body vessel (42) with a radioactive source (16) includes an elongated tubular catheter (14) and an axially flexible support structure (12) on a distal end of the catheter (14). The catheter (14) has proximal and distal ends, and a lumen (18) for receiving a radioactive source (16). The support structure (12) is formed from a plurality of filaments (22) which are helically wound and interwoven in a braided configuration and has a plurality of alternately spaced unconstricted (32) and constricted (30) regions. The unconstricted regions (32) are radially compressible and self-expandable from a positioning diameter when the device (10) is in a positioning state to a vessel-engaging, treatment diameter which is greater than the positioning diameter when the device(10) is in the treatment state. The constricted regions (30) are engaged with the catheter (14) and concentric with the unconstricted regions (32). When in the treatment state the support structure (12) causes the catheter (14) to be substantially radially centered within a vessel (42) so radiation is uniformly applied to the vessel (42) during treatment.

Abstract: A coupling assembly (10) for leak proof connection of the ends of two lengths of pipe or tubing. One end of a first pipe (12) is coupled to a coupling box (18) which is connected to or integrally formed on the end of a second pipe (14). The coupling box (18) has threads for engaging a nut (24) for securing the coupling. The coupling box (18) has a bore for receiving the end of the first pipe (12). The end of the first pipe (12) has an outer tapered surface for engaging an inner tapered surface of the coupling box (18) to form a metal to metal seal between the first pipe (12) and the coupling box (18). The bore also contains an engager (20, 22) for coupling the nut to the first pipe. The engager includes a split ring (20) which has a longitudinal slot. The split ring has internal circumferential projections or gripping teeth (80) which are aligned with external circumferential projections or gripping teeth (38) on the end of the first pipe (12). As the nut (24) is tightened, the split ring (20) is compressed so that the gripping teeth (80) of the split ring are brought into engagement with the gripping teeth (38) of the first pipe. The split ring (20) and the first pipe (12) are then moved relative to the coupling box (18) so that the outer tapered surface (40, 41) at the end of the pipe is forced into metal to metal sealing contact with the inner tapered surface (50, 52) within the bore of the coupling box (18).
