[Also in Groups XII, XXVII and XXIX] A device for introducing a liquid, e.g. lubricating oil into a stream of gas comprises a duct through which compressed gas is passed, valve means positioned in the duct and capable of producing a pressure drop on the gas flowing therethrough and at least one throughway in the duct having its outlet located at a position of reduced pressure produced by the valve means and communicating with a source of liquid the pressure of the liquid being substantially equal to the pressure upstream of the valve means whereby the liquid can flow through the throughway in accordance with the pressure drop produced by the valve means the valve means being so biased as to produce a pressure drop which will produce a liquid and gas mixture of the desired proportions. As shown, the stem 7 of the valve member 6 is a loose fit in the lower wall of the chamber 1 so that there is an air leak from the upstream side of the valve member 6 into the reservoir 10. The valve stem includes a light thin-walled tube 22 closed at its lower end and arranged to be charged with the same oil as the reservoir and to retain a constant volume of oil therein despite the consumption of oil from the reservoir. The device may be modified by replacing the jet 18 by a ring of small diameter holes or jets formed in the shoulder of the seating 5 the holes or.jets being connected by a common pipe 16 to the oil reservoir 10. In place of the hole 20 a small groove may be formed in the seating 5 or in the valve member 6. The valve member may be arranged for movement in directions other than upwardly and downwardly. In such an arrangement the stem 7 would not be able to extend into the reservoir and the damping disc 15 would not be provided.

Abstract: 1376773 Apparatus for treating textile webs E KUSTERS 8 Aug 1972 [14 Aug 1971] 36874/72 Heading D1L A rotatable guide drum 1 [Fig. 2] for use in apparatus for washing textile webs comprises an axle 2, a bearing tube 3 mounted on the axle 2 for rotation therewith, a plurality of bearing bars 4 mounted parallel to and radially spaced from the tube 3 via flexible links 5 to form the material guiding surface of the drum 1, and means for displacing the bearing bars axially of the tube 3 during rotation of the drum to alter the radial displacement of the bars (and thus the web) from the longitudinal axis of the drum. As illustrated each bearing bar 4 may be formed in two halves with a gap 8 therebetween and the links 5 of each half inclined in opposite directions. Alternatively the bars may be formed in one piece with alternate bars round the periphery of the drum arranged with their links 5 inclined in opposite directions (Fig. 9, not shown). The axial displacement of the bearings bars may be occomplished by providing the ends of each bar with rollers 9 guided on an appropriately shaped guide cam 10a (Fig. 3) or by an element 11 displaceable by a controlled drive (not shown) on axle 2 and acting on the bars via articulated members 12 (Fig. 4). The flexible links 5 may be in the form of rigid bars attached to the bars and/or the tube either by means of a pivoting linkage (Fig. 5, not shown) or a fixed resilient mounting (Fig. 7, not shown) or they may be in the form of resilient leaf springs fixedly attached to the bars and the tube (Fig. 6, not shown). The radial displacement of the bars with respect the tube 3 moves the textile web vigourously to and fro in the treatment medium and the simultaneous axial movement of the bars prevents curling of the edges of the web and centres the web on the drum surface. When used for guiding a textile web 20 through a washing liquid chamber the displacement means are preferably arranged to displace alternate bars 4 radially towards and away from the bearing tube 3 and as shown in Fig. 2 the links 5 are inclined at an angle of 45 or less to the axis of the drum so that a relatively large radial displacement of the web is achieved by only a small axial displacement of the bars.
