Abstract: 756,590. Adding liquids to spinning solutions. ALGEMENE KUNSTZIJDE UNIE N.V. Feb. 23, 1954 [April 17, 1953], No. 5329/54. Drawings to Specification. Class 2 (2). A predetermined proportion of a lowviscosity liquid is added automatically and continuously to a stream of a viscous spinning solution by suction into a pipe through which the spinning solution is pumped by means of two gear pumps in tandem, the point of introduction being located between the pumps and the pump preceding this point having a smaller capacity than the one following it. In the example a viscose spinning solution is supplied under pressure from a reservoir through a main supply pipe, and about one-eighth of the rate of flow through the main supply pipe is shunted through a shunt pipe in which is located a pump adjusted to deliver 144 cc./min. of viscose through the shunt. About 12 cm. further along the shunt is a second pump adjusted to a capacity of 168 cc./min. As a result 24 cc./min. of a dyestuff solution or a pigment suspension is drawn from a reservoir, through a supply pipe communicating with the portion of the shunt between the two pumps, and is added to the stream of viscose solution flowing through the shunt. The shunt and the main viscose supply pipe discharge the viscose into a mixer from which the dyed or pigmented viscose is delivered to the spinning machine. The system dispenses with a metering pump for the low viscosity liquid to be added. Specification 374,356, is referred to.

[Class 83 (iv)] [Also in Group XI] To reduce the effect of the unavoidable embrittlement produced in a filament-supporting rod when a filament is welded thereto the embrittlement is localised by providing the supporting rod 7, Fig. 1, with an intermediate portion 20 which is deformed into an angle section to form a flange 22, Fig. 4, in a plane of transverse stress and a flange 21 extending cross-wise of the flange 22, the filament being welded to the side of the cross-wise flange which is remote from the flange 22. As shown, the supporting-rod 7 is of circular cross-section with an intermediate portion 20 of its length deformed into a T-shaped cross-section. across which the coiled end of a filament 18 is welded. The end of the filament is reinforced by a short metal rod or spud 19 which is gripped tightly by the convolutions of the coil. Welding is effected by a pair of electrodes 23, 24 of which the lower electrode 23 is slotted to receive the T-shaped portion of the filament supporting wire and provide a clearance around the flange 22 so that the heat is localised substantially across the top flanges 21 in contact with the filament 18. The upper electrode 24 has a transverse semi-circular depression to receive and engage the adjacent end coil of the filament. Each electrode is preferably of the material which is in contact with it during welding, e.g. molybdenum for the electrode 23 engaging the filament supporting rod 7 and tungsten for the filament-engaging electrode 24. During welding, the end portion of the filament is welded to the support 19 at a point remote from where they separate, thereby ensuring that the part of-the filament adjacent the latter point is free from embrittlement.
