Title: Apparatus for heat fixing of continuous multifilament
Inventor: O'BRIEN PATTON THOMAS
IPC: D02J13/00
Filed: 1969-03-28
Abstract: An apparatus for heat fixing of a continuous multifilament roving or strip (18) which has for example been previously cold and/or hot drawn in one or more drawing stations, the essential feature of which is that the strip is taken backwards and forwards over guide rolls (20) to give an extended path through a suitably insulated chamber or oven (10) in such a way that it passes on both the forward and return paths over chambers (38) into which hot air is introduced by means of the fans (42) and out of which the air flows directly onto the strip (18) by means of a series of openings or nozzles distributed over the top and bottom faces of the chambers facing the moving strip. The chamber height decreases from one end to the other in the opposite sense in alternate chambers. The heated strip then preferably passes into a water bath through which it is guided by tensioning rolls which maintain the strip at constant length while it is cooled down to its stable form, prior to cutting it up to form staple fibre.

Title: Melt stirring for desulphurising of pig iron
Inventor: EICHBAUM GERHARD
IPC: F27D27/00
Filed: 1970-04-28
Abstract: Reduction of the S content in pig iron, based on the intermixing of molten metal and slag as the result of waves induced on the melt surface, consists of the generation of a wave in the melt where the slag is kept on the surface, a liquid metal flow being effected across the direction of the travel of this wave. This is effected by means of a mechanical stirrer, the cross wave being formed as the result of a suction effect behind the stirrer. The method achieves optimum desulphurising agent - melt contact.

Title: Heat treatment appts for metal workpieces, - with a molten salt quenching bath, the water content of which is automatically cont
Inventor: KEOUGH WILLIAM ROBERT
IPC: C21D1/74
Filed: 1971-10-01
Abstract: Heat treatment appts. for metal workpieces has an adjustable oven atmosphere which is desirably at overpressure. The preheating chamber has an inlet at the same height or less than the height of the inner base of the chamber oven. A cleansing passage is provided to remove rising vapours from the drop shaft and prevent them from entering the oven chamber, as well as to prevent contaminants from penetrating into the quenching bath. This is effected by passing in gas at overpressure through one opening and sucking it off through a second opening above the first opening. A control mechanism regulates the concn. of the quenching bath and feeds in water from a flushing vessel as a function of the salt concn. in the quenching bath, if this exceeds a predetermined value.
