A method for introducing yarn into a pneumatic yarn texturizing means, in which the yarn is positioned across the inlet orifice of the texturizing means, a stream of fluid is forced against the yarn to introduce it into the orifice in the form of a loop and a yarn cutting device, located downstream of the orifice in the direction of movement of the yarn, is actuated, its operation being synchronized with that of the fluid stream.

Method for introducing a yarn into a pneumatic yarn texturing means

Hollow fiber apparatus for the fractionation of fluid, especially useful as an artificial kidney, is disclosed, characterized principally in that it comprises:

Hollow fiber apparatus for the fractionation of fluid especially useful

The invention concerns an improved hollow fibre apparatus for the fractionation of fluid, comprising; a mandrel, sealing elements located at the ends of the mandrel and by which the hollow fibres are held, the fibres extending from one sealing element to the other, at least one of these sealing elements being traversed by the hollow fibres so that open ends of the fibres are exposed at an outer side of such sealing element, a casing, which is arranged at least around the hollow fibres and the sealing elements and defining a chamber between the inner wall of the casing, the opposing inner sides of the sealing elements and the mandrel, first inlet and/or outlet means for introducing and/or discharging of fluid through the inside of the hollow fibres, and second inlet and outlet means for introducing and discharging of fluid into the chamber outside the fibres, said second inlet and outlet means opening into and from the chamber at the periphery of the mandrel and adjacent the inner sides of each sealing element.

Hollow fibre apparatus

A process and apparatus are disclosed for the simultaneous preparation of several hollow fiber devices especially useful for fluid fractionation operations, wherein at least one hollow fiber is wound around means, at least three in number, located in different planes thereby obtaining with this fiber an envelope having a polygonal section, which can be cut in at least two places as it is formed, so as to obtain at least two distinct groups of hollow fiber lengths. Various specific embodiments are described.

Method and apparatus for simultaneous production of plural hollow fiber

The invention concerns hollow fibre apparatus for the fractionation of fluids which comprises,

A device for introducing yarn into a pneumatic yarn texturizing means, in which the yarn is positioned across the inlet orifice of the texturizing means, a stream of fluid is forced against the yarn to introduce it into the orifice in the form of a loop and a yarn cutting device, located downstream of the orifice in the direction of movement of the yarn, is actuated, its operation being synchronized with that of the fluid stream.
