Abstract: An improved screw-type extruder intended to increase the output obtainable from a machine of certain dimensions while maintaining a satisfactory quality of the material extruded. This result is obtained by providing in the homogenization zone a thread crossed by a multitude of narrow passages, and in the feed zone means for overfeeding the plasticizing zone. These overfeeding means may, for example, consist in providing in this zone a cylinder grooved longitudinally or spirally or a double-screw section producing a forced pushing of the material toward the plasticizing zone.

Abstract: This invention relates to a composition containing (A) a bridging agent, (B) a hydrocarbon oil and (C) an organopolysiloxane fluid, in which the organopolysiloxane fluid (C) is immiscible with hydrocarbon oil (B) in the absence of bridging agent (A) and a process for treating organic fibers therewith. The bridging agent is obtained from the reaction of a hydrolyzate of a diorganodihalosilane with a primary, secondary or tertiary alcohol, in which the hydrocarbon group of the alcohol is a saturated or unsaturated branched chain or an unsaturated linear chain and contains from 12 to 28 carbon atoms.
