A centrifuge includes a power exchange rotor of efficient design which is provided with at least one channel member for guiding the flow of material therethrough from a first end exposed to a source of the material, which is a feed source in a rotor used as a feed accelerator and is material discharging from the bowl treating zone in a rotor used in power recovery. The channel is so formed as to c...

A device for untwisting the end of a yarn in a pneumatic yarn splicing apparatus comprising a yarn end untwisting nozzle pipe for jetting a compressed air in the direction toward the axis of the pipe so as to cause the yarn end to be untwisted, in which the point at which the yarn is inserted in the opening of the pipe can be determined by a positioning member mounted adjacent the opening.

A yarn splicing nozzle unit in which ends of two yarns are spliced by applying compressed fluid thereon. A yarn splicing hole of the yarn splicing nozzle unit is divided in a axial direction thereof to form two yarn splicing chambers having their axes displaced from each other, a yarn inserting slit is formed commonly to the two yarn splicing chamber and compressed fluid jetting holes for jetting ...

A yarn splicing apparatus including a yarn end untwisting device wherein ends of two yarns are untwisted and spliced by an action of fluid. An untwisting nozzle pipe of the untwisting device is mounted on a block independently and removably mounted on a yarn splicing body block having a yarn splicing hole.

An apparatus for forming composite, fiber/resin components from fibrous, resin-impregnated tape comprises a gantry 11 for positioning a tape applicator head assembly 413 over a mold structure 412, which defines a mold surface of planar or contoured configuration. A control system is employed to control the movement of the tape head 413 over the mold surface 412 comprising a programmable means for ...
