Title: Two-part extruder head for extruding at an angle to the machine axis - with one part having a groove engaged by the acutely angled end of the other part
Inventor: SCHMIDT WALTER
IPC: B29C48/07
Filed: 1975-10-08
Abstract: A screw-extruder head, allowing the extrudate to issue at an angle w.r.t. the machine axis, comprises 2 parts between which the extrusion cpd. is conveyed in ducts in the contact faces, and which are clamped together by screws and a bar with holes. The contact face of the two components is a plane inclined at the same angle under which the extrusion cpd. issues from the extruder. That part facing the extruder has a groove into which the acutely angled end of the other part engages. The extruder head construction is less subject to wear and tear by the extrusion cpd., esp. when this contains solids e.g. fillers, than prior-art extruder heads. This saves machine maintenance costs and ensures better homogenisation of the extrusion cpd. There is less tendency of the extruder head being fouled by polymer remaining in the head.

Title: Fluid treatment of fabrics, integral with other processes - comprising first aq. fluid followed by organic solvent to (partially) replace water
Inventor: SCHUIERER MANFRED
IPC: D06B9/00
Filed: 1977-01-25
Abstract: In a fluid-treatment process for textile goods, the fabric is subjected to a aq. fluid in a first stage and, in a second stage, at least part of the water is mechanically displaced by the application of an organic solvent. The first treatment stage is incorporated in a finishing process, such as fulling a fabric with a woollen content. Preferred solvents used in the second stage are perchloroethylene/methylene chloride or fluoro hydrocarbons. As the fluids use in the first and second stages cannot mix, they are drawn separately from each stage and the organic solvent is distilled in two stages with the sepd. water added in the second distillation stage. The organic solvent is sprayed on the fabric in the second stage of the process and the fabric is then dried with the help of saturated steam and the fabric glazed durign the drying stage. The system reduces the amt. of treatment fluid used, and allows it to be incorporated and integrated in other fabric-finishing processes.
