摘要： Si material, which has been considered to be very brittle, and hard to bend, is heated to at least its brittle-ductile transition temperature. A bending moment is applied to a heated portion of the Si material so that a slip deformation is generated. Whereby it is possible to perform bending, and to greatly improve a degree of freedom for machining the Si material. The Si material has a brittle-ductile transition temperature which transfers from a brittle to a ductile state at its brittle-ductile transition temperature. At the transition temperature or more, the Si material is in a state that a slip can to be generated between its crystals in response to a bending torque applied thereto. Thus, when a bending moment is applied to the heated portion of the Si material which is heated to the transition temperature or more, a slip is generated between lattices or between crystal grains in the heated portion, so that the Si material is deformed.
摘要翻译：被认为是非常脆的且难以弯曲的Si材料被加热到至少其脆性 - 延性转变温度。弯曲力矩施加到Si材料的加热部分，从而产生滑动变形。由此可以进行弯曲，并且大大提高了Si材料的加工自由度。 Si材料具有脆性 - 延性转变温度，其脆性 - 延性转变温度从脆性转变为延性。在转变温度以上时，Si材料处于响应施加于其的弯曲转矩而在其晶体之间产生滑移的状态。因此，当加热到转变温度以上的Si材料的加热部分施加弯曲力矩时，在加热部分的晶格之间或晶粒之间产生滑动，使得Si材料变形。

摘要： A machine and method for forming a spring coil in a length of hollow, cylindrical thermoplastic tubing comprises clamping the ends of a predetermined length of cylindrical thermoplastic tubing between first and second opposing spaced clamping members. In the machine, these clamping members include aligned first and second sections of a mandrel. These first and second clamping members then are rotated relative to one another by a predetermined amount selected to be slightly in excess of 360°, while the mandrels are simultaneously moved toward one another, to shorten the distance between the ends of the length of tubing, while the coil is formed. At the end of this relative rotation, the mandrel sections engage one another. The clamped tube, with the coil now formed around the mandrels, is rotated and simultaneously heated to the thermosetting temperature of the tubing. After a sufficient time to establish thermosetting of the coil, the heat is removed. Rotation continues while the tube is cooled. Following the cooling cycle, the apparatus operates to release the tubing with the formed coil in it from the machine.

摘要： An apparatus is disclosed for thermosetting thermoplastic tubes in a predefined shape having at least one bend. The apparatus includes an oven with an interior chamber which is heated to a temperature approaching that at which the tube thermally deforms. An elongated former has a channel dimensioned to receive the tube, and this channel has the predefined shape. A thermally absorbent coating is disposed only on a surface of the former adjacent to and extending across each bend of the former. This thermally absorbent coating locally adds the thermal energy required to reset the memory of the tube at the bend location. A conveyor extends through the oven chamber from an inlet end and to an outlet end of the oven, and the former is attached to the conveyor.

摘要： A machine and method for providing a folded liner for insertion into a pipe, comprises an upper section and a lower section. A flattened heated thermoplastic liner is fed downwardly through the upper section to the lower section, where it is redirected and fed substantially horizontally from the lower section. The flattened liner introduced to the upper section is broadly indented at one side of the liner and is then more acutely indented to provide loops disposed side-by-side in a substantially horizontal direction. The lower section reorients the loops so that they are stacked side-by-side in a substantially vertical direction. The liner is cooled as its leaves the lower section to maintain its cross-sectional configuration. The upper section is separable from the lower section, and portions of the upper and lower sections are displaceable and removable to facilitate insertion of the liner into the machine and removal of the machine from the liner.

摘要： An endotracheal tube having utility in one lung ventilation has a curvature of predetermined radius formed in its distal end so that it is easily introducible into a left bronchus or a right bronchus of a trachea. The curvature is produced by first inserting a straight copper tube into the distal free end of a conventional straight endotracheal tube. The copper tube is then bent into the desired radius of curvature and the distal end of the endotracheal tube is inserted into an oven at a temperature of about one hundred seventy degrees to soften the thermoplastic materials of which the endotracheal tube is made. After the thermoplastic materials have softened and conformed to the curvature of the copper tube, the distal end is allowed to cool and the copper tube is then removed therefrom. When cooled, the distal end of the endotracheal tube maintains its curvature when the copper tube is withdrawn due to the thermoplastic quality of the materials from which the endotracheal tube is made.

摘要： A method and apparatus for making a pipe liner and the pipe liner itself. A thin walled pipe liner, after being provided cooled from a spool or extruded in tubular form and cooled, is deformed to a smaller cross section at ambient temperature. The pipe liner is then encased and held in its reduced cross section deformed shape by a protective sleeve which is co-extruded directly over the pipe liner. The sleeved pipe liner may then be wound on a drum for transport to a remote location. Ducts for water may pass through the pipe liner. Other ducts, for example, for fiber optics, may pass through the sleeve either within or outside of the deformed pipe liner.

摘要： Apparatus for molding an annular article, such as a radiator hose, from an organic material, such as an elastomeric material, the apparatus having a mandrel with an external surface against which an inner surface of the article is molded. The mandrel also has an end extension of reduced radial extent and an end cap is releaseably secured to the extension to provide a generally transversely extending annular surface against which an end of the article is molded. The end cap has a passage extending therethrough at a location adjacent to an adjacent portion of the extension and in a plane extending generally transversely to a longitudinal centerline of the article, and the shank of a generally J-shaped locking member is slidably inserted in the passage. The locking member is resiliently biased towards a position where a portion of the locking member disengageably engages an annular recess in the extension to lock the end cap in position relative to the extension.
