Title: Process of and apparatus for the dyeing or analogous treatment and subsequent handling of yarn packages
IPC: D06B5/16
Filed: 1923-10-12
Abstract: 227,201. Brandwood, J., Brandwood, T., and Brandwood, J. Oct. 12, 1923. Circulating or passing fluids through materials on perforated tubes.-In a process and apparatus for the treatment of yarn in wound form such as cheeses, with dye liquids &c., the cheeses 13, Fig. 1, are placed on tapered, fluted or tubular perforated spindles 11 fitting in holders 14, 15 screwed to the upper plate 6 of a chamber having a circular flange member so that the apparatus may be placed in a dyeing keir as described in Specification 190,760. Each holder is provided with an inwardly-projecting slide member 16 to engage between two flutes of the dyeing spindle and a thumbscrew 19 to keep the spindle in position. The upward movement of each spindle is limited by a plate 20. Washers 21 are first placed in position, then cheeses are placed on the spindles and these may be compressed by the devices described in Specification 224,683. Dye liquor is then forced into the chamber 5 through openings 7 by a pump, and proceeds along the flutes &c. of the spindles through the cheeses into the dye bath, as described, for example, in Specification 210,661. The flow of liquid may then be reversed. The thumbscrews 19 are then removed and pressure is applied to the tops of the spindles to force them downwardly, the cheeses remaining stationary. Owing to the taper of the spindles, the cheeses are loosened and may easily be removed. They are then dried, and to prepare them for further handling their bores are expanded by means of a conical metal tool shown in Fig. 5, which is recessed to receive a wooden or other central holder 27. The tool being first introduced into the bore of a cheese, this cheese can readily be placed on the holder. The spindles may be pressed downwardly by n pressure member 22, Fig. 4, having a recess 23 to receive a pin on a pressing lever pivoted on a central rod. Lugs 24 on the member 22 may engage slots in the spindles. The invention may be applied to yarn packages placed singly on spindles.

Abstract: 521,342. Indicating - apparatus. BAILEY METERS &. CONTROLS, Ltd. Sept. 12, 1938, No. 26602. Convention date, Sept. 11, 1937. [Class 106 (iv)] [Also in Groups XXIX, XXXV and XXXVIII] Apparatus for determining and/or controlling the ratio between two variables comprises. two members 7 and 12 respectively angularly displaceable from normal positions in dependence on the magnitude of two variables, a third member 19 or 50 being jointly positioned by the two members and having a neutral position from which it is displaced if the displacement of one member is not proportionate to the displacement of the other member, and a link 23 or 5 is secured to this point controlling means which vary the relativeeffective lengths of the two members 7 and 12 from their pivots to resore the third member to its neutral position, and further means which effect an indication or control of the ratio. In the examples shown the variables are rates of fluid flow in conduits 1 and 2 and the members 7 and 12 are operated by fluid flow meters of known construction. In the first example the link 23 operates a valve 24 which controls a servomotor 28 which adjusts a link 20 in slot 11 to restore member 19 to its neutral position. The valve 24 also operates an indicator 4 through a Bourdon tube and a control valve 6 through a bellows. In the electric construction the link from member 50 operates electric contacts 58<SP>1</SP> and 57<SP>1</SP> which control motors 63<SP>1</SP> and 67<SP>1</SP> which are in parallel. These motors operate a control valve 66<SP>1</SP> and an indicator 4. Motor 63<SP>1</SP> also operates a cam 65<SP>1</SP> which operates linkage to alter the leverage of members 7 and 12 and restore the end of link 51 to the neutral point. In the second example the link 51 slides in a slot in the third member 50 forming a mechanical alternative to the construction in the first example in which a link slides in a slot in member 7.
