Abstract: A belling machine (1) forms end sockets equipped with an integrated seal on pipes (3) made of thermoplastic material using a forming mandrel (4) on which an annular seal (5) was previously placed, diametrically expanded, coaxially and in a predetermined position. A loader (8) for loading the annular seal (5) on the mandrel (4) is able to move between a arming position, in which the loader is spaced from the belling axis (b) and does not interfere with the mandrel (4) movement along the belling axis (b), and a loading position, in which the loader is coaxial with the belling axis (b) and is located between the mandrel (4) back position, disengaged from the pipe (3) and the mandrel (4) forward position, inserted in the end (30) of the pipe (3). An annular seal (5) is placed in a positioner (10) which holds it in an operating position for the action of an arming device (9).

Abstract: A mold core is provided for producing an overmolded flexible valve. The mold core comprises a mold body, a piston assembly, a piston retaining means, a collet bit positioning means and at least two collet bits. The mold core has a cylindrical void in a distal end and has a pressure means communicated with the cylindrical void. The piston assembly has a piston head sized and adapted for axial movement in the cylindrical void, with a piston shaft extending axially from the head. The shaft is tapered from a larger first diameter at one end to a smaller second diameter at the other end. The piston retaining means has a bore through it to allow insertion of the piston shaft. Each of the at least two collet bits has an inner cylindrical tapered surface segment, the taper of the surface segment being essentially the same as the taper in the piston shaft, and an outer cylindrical surface segment, sized and adapted to be inserted inside the flexible valve.

Abstract: Disclosed is a method for the manufacture of film made of polymer based material that is particularly well suited to open-pore type cross-linked polymers. The disclosed method comprises the following steps: the making of a cell C comprising, between a substrate S.sub.1 and a substrate S.sub.2, a compound comprising a precursor of the polymer P, at least one of the substrates S.sub.1 and/or S.sub.2 being soluble in a solvent .SIGMA..sub.1 and/or a solvent .SIGMA..sub.2, said solvent .SIGMA..sub.1 and/or said solvent .SIGMA..sub.2 being a non-solvent for the polymer P; the polymerization of the polymer P within the cell C; the immersion of the cell C in the solvent .SIGMA..sub.1 and/or the solvent .SIGMA..sub.2 so as to eliminate the substrate S.sub.1 and/or the substrate S.sub.2. Applications: liquid crystal devices, molecular sensors.

Abstract: The present invention pertains to a device for preparing and feeding a monolithic ceramic mass into a metallurgical melting vessel, including a mixer 30 and a feeding device 32, characterized in that the mixer 30 and the feeding device 32 are designed as a compact unit 28 for arrangement above the metallurgical vessel, wherein the mixer 30 and/or the feeding device 32 are arranged relative to one another and movably such that the mass prepared in the mixer 30 can be directly introduced at any desired point of the metallurgical vessel via the feeding device 32.

Abstract: A process and apparatus for the commercial sterilization of thin-walled, high-profile plastic containers, which are hermetically sealed with an easy-peel aluminum foil/plastic-coated lid stock material. The apparatus is a rack of molds, each mold having a recessed groove to support the lip of the plastic container and a mold lid having a rigid portion covering the lid and a resilient portion inside the rigid portion to permit the lid of the plastic container to expand in a controlled manner during sterilization. The rigid portion of the mold lid can be angled to fit the contour of the expanded container lid.

Abstract: A method and tool for fabricating composite shafts with at least one flared end. The tool includes a specially adapted end fitting for each flared end which define the angle and direction of flaring. The end fitting includes structure for conforming/compacting the composite material at the flared ends either during and/or after the composite build-up is completed and during cure. The conforming/compacting insures that the external surfaces of the flared ends achieve dimentional control and a machined like quality without the necessity of machining.

Abstract: A flange made of fiber-reinforced thermosetting synthetic resin comprises at least one flange section extending in an axial direction, which is fitted, or can be fitted, on a tubular part to be provided with a flange. The flange section joins the inside face of the flange which, together with an outside face of the flange, defines the flange. The flange has several fibre-reinforcement layers laid around each other and extending in an axial direction, and which are spirally wound up. The flange section extending in the axial direction also consists of fibre-reinforcement layers and thermosetting synthetic resin. In the region of the angular intersection between the inside face of the flange and the flange section extending in the axial direction, there is situated a reinforcement layer which prevents crack formation and which extends from the inside face of the flange to the flange section extending in the axial direction.

Abstract: A mould portion and/or protective element of the type consisting of a material subjected to deformation is disclosed. A method and a device for manufacturing such a mould portion and/or protective element are also disclosed.The mould portion and/or protective element is preferably intended to be used as a mould portion in moulding an article and/or as a protective element to prevent access of soil and water to a surface portion of the article during transportation and storage thereof.Such materials subjected to dimensional changes as can be used as mould portions and/or protective elements present the advantages of being inexpensive and permitting removal of the article without difficulty. One such material is for example cellular plastics. The dimensional changes, however, have entailed so great difficulties in using mould portions and/or protective elements of such materials that they have made the use of the material impossible.

Abstract: An insulated pipe joint and a method for producing the joint in which first and second tubular portions are joined through an insulating member disposed in a gap between the first and second tubular members. The first tubular member has a flange portion at one end thereof while the second tubular member has a cap portion which accommodates the flange portion of the first tubular member with the gap being formed between the cap and flange portions. The insulating member disposed in the gap hermetically couples the first and second tubular members while electrically insulating them from one another.

Abstract: The present invention is directed to an article and processes for repairing fluid (e.g., liquid and gas) leaks in pipes, including, for example, bell and spigot joints.The device and process of the invention incorporates an elastomeric sleeve that extends around the pipe and longitudinally to either side of the leak. The sleeve contains a resin injection port with means to prevent escape of resin at a pressure above a predetermined pressure, and a fluid venting port with pressure-relief means to permit the escape of fluid at a predetermined pressure above the pressure in the pipe to be repaired.

Abstract: A die cavity is delineated by the surfaces of a pair of die members and the threaded surface of a first of a pair of thread engageable members, one of the die members thread engaging a part of the threaded surface. A synthetic polymeric resin is injection molded in the cavity to produce a second member in precise thread engagement with the first member and the cavity is then opened to release the thread engaged members.
