摘要： The method for manufacturing turbulators predisposed to be used in heat-exchanger or similar devices provides to prearrange a first twisting head (11) and a second twisting head (21) along a working direction (A) in a position coaxial according to a longitudinal axis (A1), to feed a portion of elongated shape material (100), for example wire or band, unwinding from a feed device (2) towards a load device (3); to feed said portion of said elongated shape material by means of a feed device (2) carrying auxiliary unwinding means (24) to arrange said fed portion (101, 102, 103) of filiform material in U-shape; to lock one end of the portion of material (100) to the first twisting head (11), and an opposite part of the portion of material (100) to the second twisting head (21). Subsequently, a relative rotation motion is operated between the first twisting head (11) and the second twisting head (21) according to the longitudinal axis (B1) and then the portion of material (100) so twisted is extracted.

摘要： A method is disclosed for fabricating a hollow bar (10) that forms elements of a grille or railing of a metalwork piece where the bar is twisted manually, machine-assisted or automated machinery, into a spiral form for decorative or ornamental purposes. By providing the hollow bar (10) to be comprised of separate longitudinal parts (200, 202) which may be hinged-joined to complementarily fastened to each other to form the hollow bar (10), the longitudinal joint means (204, 206) are thus amenable to increased torsional stress, such that each of the parts (200, 202) may be twisted without breaching the material's fatigue limit and the bar (10) as a whole capable of being twisted with more spiral turns within its elasticity limits. The twisted bar may thus be released for re-working for adjustments or re-installation. A number of exemplary joint embodiments, internal and external bracing accessories are also disclosed to cater for the different longitudinal part fabrication, e.g. by extrusion or roll-milling.

摘要： A heat exchanger has a first thermally conductive tube for conducting a fluid and a second thermal conductive tube for conducting a fluid. The first thermally conductive tube forms a first loop while the second thermally conductive tube forms a second loop. The first loop neighbors the second loop.

摘要： There is provided a plastic working machine for plastically working a tube (33) by employing tube holding and spinning means for holding and spinning the plastically workable tube (33) around the axis of the tube (33) and first and second plastic working tools (57,58) which face to each other so as to pinch the tube (33) in the radial direction of the tube (33) and which are movable along the radial and axial directions of the tube (33) while being pressed against the tube (33). The plastic working machine executes a step of plastically working the tube (33) by the first and second plastic working tools (57,58) by continuously spinning the tube (33) around the axis thereof and by applying compressive load or tensile load along the axial direction of the tube to the tube (33).

摘要： Piston rings are described which comprise a single ring (10) in a co-operating piston ring groove (11), the piston ring being planar, having a dished section, and a planform giving desired radial pressure distribution on a co-operating cylinder wall and which ring is made from a steel resistant to stress relieving at the piston ring operating temperature. The dishing may be either positive or negative and may lie in the range from 0.025 to 0.75 mm. A method and apparatus are also described for the manufacture of such rings.
