Abstract: The invention deals with problems arising in lubrication of the helical cam grooves of cam drums used in thread traversing mechanisms of winding machines. The drum (10) is provided with an internal space (18) acting as a lubricant reservoir. A passage (26) extends between the space (18) and the groove (16) so that centrifugal force urges lubricant outwardly along the passage (26) from the space (18) towards the groove 16). Flow along the passage (26) is controlled by a porous sintered metal body (32) which permits a desired degree of a given lubricant to pass along the passage (26) at a given rotational speed.

Abstract: A field effect transistor (1) bias circuit is presented which exhibits a low impedance for small signals and a high impedance for large signals. This circuit uses an operational amplifier (6) to provide a temperature compensated low inpe- dance voltage source for the gate bias which is optimal for small signal operation. In the presence of a large signal, the gate begins to draw current. This causes the operational amplifier to saturate and transforms the bias circuit into a high impedance source, which is optimal for large signal operation.

Abstract: An elastic fiber having improved elastic properties has the following properties:
     (a) each elastic fiber is composed of at least two thermoplastic polymers,   (b) at least one of the thermoplastic polymers has crystallinity capable of forming a row structure.   (c) at least one other of the thermoplastic polymers has crystallinity capable of forming lamellar crystalls, and   (d) each elastic fiber has a row structure.   
     These fibers can form an elastic fibrous assembly. The assembly, which can be used as a material for clothes, can be produced by extruding a combined polymer melt of at least two thermoplastic polymers including polymers (b) and (c) through a mesh spinneret (7) including- many closely arranged small openings and having an opening ratio (a) of at least 10%. Extrusion is carried out while generating Joule heat in the partitioning members of the spinneret, for example by supplying electric current through copper plates (8) to the spinneret (7). The vicinity of the extrusion surface of the spinneret is cooled by supplying a cooling fluid such as air from a feed device (11). The melt is converted into fine streams by the partitioning members. The solidified fine streams (13) are taken up, for example by a take-up roller (12), and are heat-treated by suitable means (14).
