Making a reservoir

A process for forming a reservoir 200 comprises blow-moulding a hollow cylindrical extrudate within a mould which may have a serpentine cavity. The extrudate has first and second openings through at least one of which pressurised gas is inserted to effect the blow moulding to expand a portion of the extrudate and to fill a cavity of the mould and form one opening to have a desired internal diameter 252. A portion of the extrudate is cross-linked, preferably with an electron beam, to set the internal diameter and give it shape memory characteristics. The internal diameter is enlarged, preferably to a diameter larger than a connection profile and the end of a connection profile is inserted into it. The internal diameter may be enlarged by insertion of the connection profile. An external stimulus such a temperature or time is applied to contract the internal diameter to compressively seal onto the connection profile. A second connection profile may be applied to the other end of the tube.

BLOW MOLDING METHOD AND APPARATUS

ABSTRACT OF THE DISCLOSURE When blow molding elongated serpentine tubes or similar articles, loading of the mold cavity with the parison can present a problem. The parison can stick against the wall of the mold cavity. Moreover, a large diameter parison must be used, i.e. the parison must have a diameter equal to the total width dimension of the article, and consequently a large volume of flash is produced. The flash must be trimmed and recycled. In order to avoid these problems, inserts are placed in the mold to define portions of the mold cavity, particularly at corners. Air under pressure is fed into passages in the outer surfaces of the inserts and discharged through small orifices in such inserts against the parison to guide and drive the latter fully into the mold cavity. A vacuum can also be applied to the end of the cavity remote from the parison entry point for drawing the parison into the mold.

PVC/CPVC composite pipe with metal interlayer and process for making it

A composite pipe has a metal conduit sandwiched between inner and outer conduits of PVC/CPVC, each of which are adhesively secured to the interlaying metal conduit with a dried, solvent-free thin layer of a thermosetting bilayer adhesive which provides a bond with the metal, which bond fails in cohesive failure. Narrowly defined limits on the thickness of each conduit are found to provide a bendable composite pipe with an aluminum interlayer; and to provide a rigid non-bendable composite pipe with a steel interlayer. Making the composite pipe which meets required ASTM and NSF test considerations requires unexpectedly critical process steps. A process for making the pipe is disclosed, as are PVC/CPVC fittings which allow lengths of pipe to be solvent-cemented in them so as to seal the terminal ends of the pipe against infusion of fluid under pressure in the pipe, thus preventing delamination.

[Solution] The tube in the plate-shaped portion Y1 with respect to the tubular foamed molded article having the tube body X1 and the plate-shaped portion Y1 joined to the outside of the tube body X1. The recessed part 106 is formed in the vicinity of the connection surface with the main body X1. As a result, at the time of mold clamping in the divided mold, the plate-shaped portion Y1 is compressed to the thickness between the cavity surfaces 10a and 10b, and the inner part of the tube main body X1. Even when the space is empty, the convex portion 18 for forming the concave portion 106 functions as a dam against the movement of the bubble cell, and the movement of the bubble cell is prevented by the convex portion 18.

Plastic tube bending method and apparatus

A plastic tube is bent by advancing the tube to position a desired first bend location of the tube at a bending/cooling station, the bend location of the tube having been previously heated by a tube heating assembly sufficiently for bending. The tube heating assembly is moved to a next desired bend location of the tube. Bending and cooling the tube at the first bend location, and heating the next desired bend location, take place in overlapping time windows, before advancing the tube to position the next desired bend location of the tube at the bending/cooling station. Total cycle time for heating, bending and cooling is thereby substantially reduced compared to carrying out heating, bending and cooling sequentially. The apparatus is controlled by PLC or PC-based programs, which effect movement via servomotors and also control other parameters such as heating and cooling times and temperatures.
