摘要： A hydrotapping power unit is disclosed that is operable to hold a hydrotapping tool in a home position adjacent a part while the latter is being hydroformed in a die cavity, to then advance the tool to pierce a hole in the hydroformed part while the part remains in the die cavity and under pressure and then continue to advance the tool to inwardly extrude the part about the hole, to then further advance while also rotating the tool at a feed rate equal to the thread pitch of the tool to thereby form a thread in the pierced hole, and finally retract while also rotating the tool but in the reverse direction and at the same feed rate to release the tool from the threaded hole. The power unit for performing these operations includes a linearly moveable shaft for holding the tool, a powered device for rotating the shaft, another powered device connected to the shaft by a lead screw connection having a thread pitch equal to that of the tool, and a third powered device that is adapted to intercept and prevent shock loading on the tool from the piercing operation and thereby on the shaft from reaching the lead screw connection.

摘要： A method is provided for joining tubes. An outer tube and an inner tube are provided. An end of the inner tube is inserted into an end of the outer tube to form an overlapped region of tube wall and form a pressure tight joint between the tubes. The overlapped region of the tubes is heated. The tubes are placed in pair of dies having a die cavity adjacent to the outer tube. Pressure is introduced into the tubes to expand the overlapped region of the tubes outwardly into the die cavity and thereby form an interlocking joint between the overlapped region of the outer tube and the inner tube.

摘要： A mandrel assembly is provided for insertion into a hollow tube to support the interior walls of the tube during bending of the tube in a tube bending apparatus. The mandrel assembly includes at least one mandrel segment that is adapted for positioning within the tube and has an exterior support surface for supporting the interior walls of the tube during bending. The mandrel segment is anchored at a fixed axial location within the tube by an anchoring device that is radially expandable and retractable between an expanded condition in which an anchor shoe is engaged with the interior wall of the tube and a retracted condition in which the anchor shoe is loose within the tube. A mandrel support rod is attached to the anchoring device for inserting and withdrawing the anchoring device into the tube when the anchor shoe is retracted.

摘要： Improved apparatus for unclogging a toilet. The apparatus includes a resilient sealing ring shaped generally to conform to the shape of the rim of a toilet, a support plate attached to said sealing ring configured such that a force exerted on the support plate is transmitted to the sealing ring to compress the sealing ring against the rim of the toilet forming a substantially airtight seal around the toilet bowl. The apparatus further includes a sealing device insertable into the toilet tank including a sealing surface configured to form a substantially air tight seal over the vent tube, said sealing device further including a member configured to mechanically block the operation of the valve such that air is substantially prevented from escaping from the bowl through the tank when the sealing ring is compressed.
