    摘要: A method and machine for flanging tube ends, the machine having pivotal inner (22) and outer (30) forming tools which flange one end of a thin metal tube (21) specifically to form a rotatable drum for laundry machines. The tools are actuated by hydraulic rams (A), (B) and (C) and the rams are actuated at different rates of movement under the control of a computer so that as forming is effected by moving both sets of tools from dispositions on a cylinder to dispositions on a disc the inner forming tools (22) have their pivot points 24 changed relative to pivot points (31) of the outer forming tools (30) resulting in relative sliding between inner and outer forming tools. The flange (51) formed has two sets of ribs, one set extending outwardly away from the tube (21) and the other set extending inwardly within the tube (21) and parts of the flange between adjacent ribs lying in a plane substantially at right angles to the wall of the tube (21).

    摘要: This connection system has particular application to releasably securing a flexible catheter to a rigid portal outlet stem received in the catheter lumen. The system includes a radial enlargement on the outlet stem and a retainer sleeve having a tubular distal segment which encircles the catheter at a location adjacent to the free end of the stem therein and a proximal segment which is composed of a pair of mirror image, hinged together, semicylindrical clamping sections, one of which is an integral extension of the distal sleeve segment and the other of which can be moved between open and closed positions so as to enable the sections to clamp around the stem enlargement and a segment of the catheter encircling the stem. A locking ring snugly encircles the sleeve and is slidable therealong between a locking position wherein it tightly engages around the sleeve clamping sections and an unlocking position wherein it encircles the distal sleeve segment. The system assures a secure, fluid-tight connection of the catheter to the stem and provides strain relief for the catheter.
