Title: Combined drawing and extrusion process - for metal tubes
Inventor: JACKSON ROBERT GARRISON
IPC: B21C1/00
Filed: 1972-02-21
Abstract: A tube which has been annealed is drawn longitudinally in a traction appts. to reduce its cross-section under cold-working condns. and in a plastic state.

Title: Centrifugal separator - for gas purificn by inward swirling flow bounded by contrarotating vortex flows
Inventor: SCHMITZ HUGO
IPC: B01D45/16
Filed: 1972-06-29
Abstract: A centrifugal separator for waste gases admits the gases through openings in the circular side walls to produce a swirling helical flow, directed inwards, with the extraction of the purified gases in the centre.

Title: Forming skeins for dyeing - by dividing hank winding into portions and securing skeins around each portion
Inventor: BABA TOMOKIYO
IPC: D05B5/00
Filed: 1973-10-26
Abstract: A bunch of continuous hank yarns are wound into a hank on pref. a former, and the hank is divided into separate hank portions around each of which loops of skein yarns are formed. Pref. a needle enters the hank between a pair of adjacent windings and two curved guide tubes are pivoted so that they pass between adjacent pairs of hank windings on opposite sides of the needle and their free ends coincide adjacent an eye in the needle, whereby the groups of windings between the needle and each guide tube define hank portions. A bunch of skein yarns are then fed pref. pneumatically through one guide tube such that they pass through the needle eye and into the other guide tube. When the needle and guide tubes are withdrawn from the hank the skein yarns form skeins around each of the hank portions and the free ends of the skein yarns afe tied together by a convensional device to form skein loops. By dividing the hank into small portions and securing smaller skein loops around then the yarns can be more uniformly dyed in a subsequent skein dyeing process.
