摘要： The invention relates to a method and an apparatus for manufacturing an extruded plastic product, the apparatus comprising at least one rotor (1) and at least one stator (2, 3) with a feed gap (4) provided between them, a groove (7) being situated on the other side of the feed gap (4), the groove pressing the material to be extruded out of the apparatus when the rotor (1) is rotated. The cross section of the groove (7) remains substantially unchanged. At the opposite side of the feed gap (4) there is positioned a countergroove (8) in such a way that a processing cavity consisting of the grooves (7), the countergrooves (8) and the clearance between them decreases at least partially continuously along the axis of the extruder. The deformation energy of the material can thus be kept as small as possible due to the unchanging cross section of the groove (7), and the material stays in the groove (7) due to the placement of the flights (7a, 8a). The material is made to move rotatably, which enables the manufacture of a laminar plastic product (11). Further, materials that would otherwise be difficult to process can also be extruded effectively.

摘要： A multilayer composite pipe structure is described. The multilayer composite pipe comprises a hollow inner conduit, a first layer of adhesive, a metallic intermediate layer, a second layer of adhesive, as well as, the outer thermoplastic layer, respectively. The hollow inner conduit is made from any rigid thermoplastic material. The outer thermoplastic layer is made from a rigid, amorphous thermoplastic polymer. This multilayer composite pipe is pressure bearing. In one embodiment, the multilayer composite pipe is solvent cementable; whereas in another embodiment, the multilayer composite pipe is heat fusible. In still yet another embodiment of the invention, the multilayer composite pipe is bendable. Furthermore, the multilayer composite pipe can be used in a fluid conduit system with fittings with an optional insert.

摘要： A pipe joint for fiber reinforced composite pipe (10, 13) has internal and external matching tapers (11, 14) with a low taper angle. A half round helical groove (16) is formed in each of the internal and external tapers (11, 14) for receiving several turns of a ductile key (17). Deformation of the key (17) in shear redistributes longitudinal loads along the length of the pipe joint. The outer member of the pipe joint (13) has a high stiffness so that internal pressure in the pipe presses the tapered surfaces (11, 14) together so that the resulting friction enhances the longitudinal load carrying capability of the joint. High external stiffness may be provided by winding the external moiety of the joint with high modulus of elasticity fiber.

摘要： The invention relates to an extruder with which material is extruded through a tool (2). Fluoropolymer is used between the extrusion material and the tool (2) for reducing friction between the material and the tool. At least the surface of the tool (2) against fluoropolymer is of a material whose thermal conductivity is greater than the thermal conductivity of ordinary tool steel. Therefore the friction heat generated can be conducted efficiently away from the interface between the tool (2) and the extrusion material towards the tool (2), whereby the wear of fluoropolymer can be reduced and thus the durability of the tool (2) can be improved. In that case the extrusion product will slip evenly out from the tool (2), whereby the surface of the product is essentially smooth without transverse microscopic stripes repeated at a specific wave length.

摘要： A guiding catheter for use in coronary angioplasty and other cardiovascular interventions incorporates a plurality of segment of selected flexural modulus in the shaft of the device. The segments which have a different flexibility than the sections immediately proximal and distal to them, creating zones in the catheter shaft which are either more or less flexible than other zones of the shaft. The flexibility and length of the shaft in a given zone is then matched to its clinical function and role. A mid-shaft zone is significantly softer than a proximal shaft or distal secondary curve to better traverse the aortic arch shape without storing too much energy. A secondary zone section is designed to have maximum stiffness to provide optimum backup support and stability.
