Abstract: 1277581 Variable-ratio control CARDING SPECIALISTS (CANADA) Ltd 28 Aug 1969 [3 Sept 1968] 41750/68 Heading F2D [Also in Divisions D1 and G3] The count of slivers in a carding machine is controlled by feeding the sliver between sensing means 5, 6, Fig. 1, whose surfaces are normally a given distance apart in relation to the setting of a control valve 9, causing variation in the distance between the surfaces to be magnified by lever means 7 to provide accurate control of the valve and causing the valve to adjust a fluid motor which varies the speed of control means 17 feeding material to form the sliver, the position of the control means corresponding with a given speed ratio without corresponding to a given position of the sensing means. In the preferred embodiment, the lever means consists of a bell-crank 44, Figs. 2A and 2B, pivotally connected at 62 to a lever 67 having a normally-fixed pivot 72 adjustable by a hand wheel 101 whereby the position of the sensing means may be adjusted without altering the speed ratio. The hand wheel is connected to the pivot by a screwed member 96a, a spring-loaded lever 94 and an eccentric shaft 84 which adjusts a lever 76 carrying the pivot 72. Gearing (not shown) interconnects the pivots 62 and 72 and the pivot 62 is mounted in bearings combined with sprag clutches to ensure that the pivots always rotate in the same sense to avoid breakdown of the lubricating film and false brinelling. An eccentric mounting 52 for the roller 5 of the sensing means in the bell-crank 44 permits a coarser adjustment of the position of the sensing means by a hand control 55. To allow the sliver to be released from the sensing means when a blockage has to be cleared, a handle 106 is rotated through 180 degrees to impart substantial movement to the shaft 84 and hence to the lever mechanism. A recirculating or planetary ball or roller bearing system 112, 113 supports a spring-loaded spool 111 in the control valve which adjusts the piston 135a of a fluid motor connected to a system of rollers which shift a belt axially on coned pulleys 144, 145 and also maintain the belt in tension. The shaft 167 on which the belt 144 is mounted is coupled to the drive for the carding machine and has a gap 172 through which the belt may be replaced after the pulley has been axially displaced. The other pulley is mounted at one end of a shaft which forms the input to the variablespeed gear and also drives a twin piston reciproeating pump 132b supplying the motive fluid for the control system. An axially-adjustable helically-grooved plug 130a receives part of the pump output to act as a variable resistance and make the supply to the control valve independent of temperature and viscosity variat ons.

Abstract: 1,184,670. Centrifugal classifiers. ALPINE A.G. 25 Sept., 1967, No. 43602/67. Heading B2P. A fluid flow classifier for separating material according to size comprises a stationary classifying chamber having a peripheral wall 15 extending substantially continuously around a classifying rotor 2 between the side walls of which classifying fluid 11, e.g. air or water, flows radially inwardly. The fluid enters the classifier housing through a channel 28, flows through openings 12, 34 in both sides of the classifying chamber, is accelerated to the peripheral velocity of the classifying rotor 2 by radial blades 13 on the rotor and flows through annular gaps 14 between the side walls of the rotor and the chamber wall 15. The material to be classified is fed through a channel 10, enters the classifying chamber through an opening 29, is accelerated by the vanes 13 and enters through one of the gaps 14 into the space 18 between the wall 15 and the rotor 2. In the space 18 the material is whirled up and separated by the entering classifying fluid air so that the coarse particles 27 are carried around towards an exit slot 22 in the chamber wall 15 and discharged through a duct 23 to which a pneumatic suction device may be connected to assist discharge. The fine particles 21 pass with classifying fluid through the rotor to be discharged through a central discharge duct 4. A branch 24 of the classifying air stream flows through the gap 25 between the rotor 2 and the duct 4 to prevent material entering the gap when the classifier is being shut down. A flared ring 26 is mounted on a side wall of the rotor to prevent unseparated material from the upper part of the classifying chamber from falling into the annular gap 25. By narrowing the exit slot 22 the coarse particles may, as a whole or partially be made to recirculate several times so as to improve separation. The interior of the rotor may be provided with radially extending zigzag shaped channels between its side walls. In a modification, the material to be classified is fed through an opening in the peripheral wall 15 of the chamber in a direction radially of the rotor and the coarse particles are discharged in an axial direction by a worm conveyor.

Abstract: 939,861. Endless conveyers. HEAD WRIGHTSON & CO. Ltd. Dec. 14, 1961 [Dec. 20, 1960], No. 43801/60. Class 78 (1). A sintering machine comprises pairs of rails 11, 12 which support a series of independent wheeled pallets 14 arranged in abutting relationship to form an endless belt. The curved ends of the rails 12 overlap the curved ends of the rails 11 and are secured at both feed end F and discharge end D to brackets 21 welded to connecting plates 22 which are secured to plates 23 fixed to the main framework 13. Shims 24 may be used between the rails and the brackets 12. The lowermost quadrants of the rails at both ends of the machine are formed to a curvature which is calculated to a law : # = (S/a)2  where # = the angle of inclination of the tangent to the curve in radians. S = the length of the periphery of the curve. a = constant which is dependent upon the unit of length used for " S." The curvature so formed is such that, during movement over these curved portions of the rails, the pallets are constrained to pivot about their central transverse axis, and adjacent ends of the pellets, during movement, are caused to roll upon one another instead of sliding relative to one another as would be the case with rails constructed as segments of a circle. The uppermost quadrants of the rails are formed as a true segment of a circle but have associated therewith cams 39, 40 for co-operating with rollers 31 of the pallets which are caused to pivot immediately prior to moving on to the upper straight section of the rails and immediately after leaving the straight section. The trailing rollers 32 of the pellets, due to portions 42 of reduced diameter, do not engage the cams 39, 40 and therefore follow the normal curvature of the rails. Pallet construction and drive.-A body casting 25 has end plates 28 bolted to it, the plates having projections 29, 30 for mounting the rollers 31, 32, and arcuate outer faces 37 for abutting engagement with faces of adjacent pallets. Inner faces 38 are formed for engagement by drive sprockets 16 provided at the feed end F of the machine. Grate bars 26, side plates 33 and sealing bars 35 are provided.
