Title: Improvements in or relating to filtering or straining apparatus
IPC: B01D29/00
Filed: 1932-03-22
Abstract: 396,156. Filters or strainers. BELDAM, W. R., Lascar House, Staines Road, Hounslow, Middlesex. March 22, 1932, Nos. 8509 and 9414. [Class 46.] In strainers formed of wire 39 coiled on a support, scraping blades 43 are provided projecting into the grooves between the coils to a depth less than the thickness of the wire, the straining wall and scraping blades being adapted to be moved relatively, preferably both axially and peripherally. The strainer comprises a casing 1 in which is rotatably mounted a shaft 21 bearing a circular base 33 carrying rods 35 whereon the wire 39 is coiled. A bar 41 having threads forming the scraping blades 43 is adapted to engage the coils. The bar 41 is mounted on a spindle 45 and springs 47 urge the blades against the coils. On rotation of the strainer, the bar 41 is gradually moved down, but, on a cam 51 forcing the blades out of engagement with the coils, the bar is forced up by a spring 49. Alternatively the upward movement may be effected by a cam. Or the cams may be omitted and the bar moved up by reversing the direction of rotation. The strainer may be fixed and the blades movable therearound. The bar 41 is tapered in cross section and widest at the side adjacent the coils so as to dig under the dirt. The blades may project little more than half the thickness of the coils and where the support is substantially circular in cross section, the face of the bar may be concave. After removal of the blades from the wire, the strainer may be moved so that the blades re-engage with a cleaned part so as to avoid pressing dirt through the wire. The cleaning may be intermittent so as to avoid electrolytic action. The wire may be wound in a helical thread formed on the support. The support may comprise an apertured cylinder having ribs whereon the wire is coiled. One rib may be omitted so as to provide a flattened part on the coils at which the blades run out of engagement with the coils and are then moved up by the spring 49. Or the wire may run under a rod at this point so as to provide a depressed portion down which dirt may be discharged to a sump. The support may comprise a two-start or multi-start thread 38, 40, Fig. 7, and the wire 39 may be wound on one thread 38 leaving spaces opposite the other thread or threads 40 into which the blades project. Further wires 61, 63, Fig. 8, may be wound in the threads 38, 40 and the wire 39 is then wound on the wires 61, 63, with or without gauze, cloth, or paper interposed

Title: Improvements in or relating to ring or other spinning frames
IPC: D01H1/38
Filed: 1929-03-16
Abstract: 329,432. Lees & Co., Ltd., A., and Taylor, R. March 16, 1929. Building-motions.-In ring or other spinning frames a delay or lost motion mechanism is provided in the heart-cam shaft gearing so that when the frame is started a " bunch " is wound at the base of the bobbin and the building- motion mechanism thereafter brought into operation. In the arrangement shown in Fig. 1, the delay mechanism comprises a catch-box, of which the part 8 is driven by a pinion 26 and rotates upon a sleeve 10 fast on the heart-cam shaft 6, and the part 7 is slidable on the shaft 6 and is operated by a lever 20. The part 7 is connected to the sleeve 10 by a coil spring 19, Fig. 2, and is provided with an arm 18 adapted to engage stop-pieces 13, 14 on the sleeve 10. In the position shown in Fig. 2 the spring is unwound ; before starting the machine the part 7 is slid into engagement with the part 8 so that the shaft is not driven until the spring is wound by the rotation of the part 7 and the arm 18 is looked against the stop-piece 14 by a spring- pressed catch 15, whereby a bunch is wound before the normal traverse is commenced. Upon completion of the winding, the part 7 is withdrawn and the spring 19 uncoils until the arm 18 engages the stop-piece 13. In the arrangement shown in Fig. 4, the catch-box also comprises two parts corresponding to the parts 7, 8, projections 39 on the slidable part engaging slots 40 in a member fast on the heart-cam shaft 6 to effect the drive. The delay action is effected by the withholding of the slidable part by means of a lever 36, which engages a lever 47 until released by an adjustable stop 32 on a wheel 28 driven by a wheel 27 on the other part of the catch-box, whereupon a spring effects the engagement of the two parts of the catch-box and the projections 39 and slots 40 and the shaft 6 is driven. This movement also removes the wheel 28 from the wheel 27 by reason of the raising of its supporting lever 29 by a lever 44 carried by the yoke 43 of the lever 47, the wheel 28 being rotated by a weighted chain 33, which is wound up during the initial movement, until a stop 31 thereon engages a fixed stop 35.

Abstract: 907,068. Fluid-pressure servomotor-control systems. FISHER GOVERNOR CO. March 9, 1961 [Aug. 1, 1960], No. 8702/61. Class 135. A pneumatic flapper-nozzle valve positioner comprises an arcuate beam 16, Fig. 4, which receives an input signal from a bellows 114 and a feedback signal from a cam 92 to locate a flapper 82 with respect to a nozzle 66. The bellows 114 acts through a fulcrum member 106 which with a fixed fulcrum member 100 defines the X-axis about which the feedback force rotates the beam while the fixed fulcrum member 100 and the cam 92 define the Y-axis about which the input force rotates the beam. The said axes are at right angles to one another. The nozzle back pressure is fed to a supplyexhaust relay valve, the output signal from which is transmitted for example to a diaphragm motor valve and to a pressure gauge. The beam 16 acts on the resiliently supported flapper through a fulcrum member 84, Fig. 3, and the flapper is rotationally adjustable to vary the proportional band. If the flapper is located above one quadrant of the beam direct action is obtained and if above the other quandrant reverse action is obtained. The cam 92 which acts on the beam 16 through a roller 88 may be contoured to give a linear or other than linear relationship between the input and output signals.
