A pipe fitting having a first body and a second body that together at least partially define a fluid flow passage. The first body defines a first portion of the fluid flow passage that extends from a first end of the fluid flow passage to a first internal opening. The second body defines a second portion of the fluid flow passage that extends from a second internal opening to a second end of the fluid flow passage. The first body has a first interface surface that surrounds the first internal opening, the first interface surface having a plurality of anti-rotation grooves. The second body has a second interface surface that surrounds the second internal opening and engages with the first interface surface. The first internal opening is in fluid communication with the second internal opening. The second interface surface has a plurality of anti-rotation fingers that are each received by and engage with a corresponding one of the anti-rotation grooves. Rotation of the second body relative to the first body is resisted by the engagement of the anti-rotation fingers with the anti-rotation grooves.

A method for fabricating a composite object with a computer-controlled apparatus, and the apparatus therefor. The comprises a reservoir containing liquid, curable first material, means to selectively solidify the first material and means to selectively deposit a second material. The method involves the steps of selectively depositing portions of the second material, and selectively solidifying portions of the first material, such that the solidified portions of the first material and the deposited portions of the second material form the composite object.

A composite part is provided and includes a component, a first set of first composite plies with finite lengths and a second set of second composite plies with finite lengths. A respective end of each of the first composite plies is wrapped around the component in a clockwise wrapping direction and includes first fibers. A respective end of each of the second composite plies is wrapped around the component in a counter-clockwise wrapping direction and includes second fibers.

A hollow-fiber-type blood processing device and methods for its manufacture include a hollow fiber membrane bundle which is obtained by bundling a large number of hollow fiber membranes into a columnar shape. A sheet body is mounted on an outer peripheral portion of the hollow fiber membrane bundle. The sheet body is expandable as a result of being woven from a sheet material. An inner diameter of the sheet body in a natural state where no external force is applied to the sheet body is smaller than the outer diameter of the hollow fiber membrane bundle.

A method for producing a sandwich component, and an apparatus for producing a sandwich component. The method includes providing a plurality of webs of material, applying at least one matrix material to an upper side and/or an underside of at least one of the webs of material, wherein applying the at least one matrix material includes applying the at least one matrix material such in different ways to create at least one zone of the sandwich component having mechanical properties that differ from mechanical properties of other parts of the sandwich component, arranging at least one core layer on one of the webs of material, and pressing the webs of material and the at least one core layer to form the sandwich component such that the core layer is arranged between at least two of the webs of material.

A method for producing a high-pressure tank capable of suppressing break of a surface resin layer due to gas pressure as well as degradation in the tank quality. The method includes winding a thermosetting resin-impregnated fiber bundle around a liner so as to form an uncured fiber-reinforced resin layer thereon, first heating in which the uncured fiber-reinforced resin layer is locally heated at a first temperature so as to leach the thermosetting resin out of the uncured fiber-reinforced resin layer to form the surface resin layer, and the surface resin layer is cured to have cracks generated therein, and second heating in which the tank is entirely heated at a second temperature lower than the first temperature, so that the fiber-reinforced resin layer and surface resin layer are entirely cured, so as to obtain the tank with the surface resin layer locally having cracks generated therein.
