Abstract: 1406650 Mixing apparatus; Fluid-energy mills; Pneumatic separation CROWN ZELLERBACH INTERNATIONAL INC 6 Dec 1972 [31 Jan 1972] 56376/72 Headings B1C, B2A and B2H [Also in Divisions B1, B8 and F4] In apparatus for mixing de-agglomerating, separating and transporting fluid-entrained particulate material, the fluid enters at 43 and issues from an annular slit 37, entraining particles from hopper 10 and attaching itself to surface 35 whereby it passes along a first flow path 11 at the end of which it encounters a fluid curtain issuing from an annular slit 16. Particles undergo de-agglomeration and intense mixing in the zone of the curtain. Fluid from the slit 16 together with any particles entrained thereby then attaches itself to the surface 17 whereby it is guided into a second flow path 21 and the entrained particles art deposited in a collector 22. Particles having sufficient momentum at the end of the first flow path may pass through the curtain and fall into a collector 27; or if their momentum is greater still may be entrained by fluid issuing from an annular slit 26, which attaches itself to a surface 68, 24 and conveys the particles through a conduit 25 to a further collector (not depicted). The widths of the slits 37, 16, 26 are screw-threadedly adjustable (Figs 2 and 3, not shown) and the assembly consisting of nozzle assembly 15 and arm 95, (together with conduit 25 and collector 27) may be axially adjusted by crank 98 to position slit 16 in relation to the flow attachment surface 17. The collector 27 may be open at 90 as shown, to entrain atmosphereic air, or may be closed and have a tangential inlet (92, Fig 5 not shown) for fluid entrained or under pressure, and a tangential outlet (93) for fluid and entrained particles. Examples and applications relate to the. separation of polyethylene fibres from water and sand, de-agglomeration of polyethylene fibres intended for making synthetic paper, separating and opening of rayon staple fibres, mixing of fibres of polyethylene and rayon, the coating of transported particles by vapours or powders, and the transport of ground metallic ores, metal particles, wood chips, cellulose fibres and cereal grains.

Abstract: 1,207,580. Rotary vane filters. G. GAUDFRIN. 2 Dec., 1968 [1 Dec., 1967], No. 57035/ 68. Heading BID. A filtering installation comprising a housing 2 divided into compartments by partitions and including filter vanes 6, 6a rotatable about an axis 19 and adapted to "hurdle" the partitions, as in Specification 1207579, incorporates: an air compressor 4 for maintaining a pressure P; a throttle 18 or 18a in the filter outlet 12 or 12a; and a regulator 17 or 17a for adjusting the throttle in response to a parameter of a liquid under treatment. As described, an upstream working air pressure P is maintained substantially constant by a throttle 14' and liquid column 14". Relatively concentrated filtrate from filter vanes 6 in mother-liquid-compartment 5 outflows at 12. Throttle 18 maintains a pressure p (< po = atmospheric) and is controlled via line 118 in response to the liquid level sensor 117 in a mother liquor supply reservoir 8. A throttle 16 in supply line 9 is controlled by a level sensor 115 in compartment 5. Thus a correct throughput level is maintained. Similarly, the wash flow-rate through vanes 6a in compartment 5a is controlled on the input side by throttle 16a and level sensor 115a; and at the output side by throttle 18a in response to a device 17a (e.g. a pH meter) which determines the solids concentration in the output wash liquid, and hence the degree of clogging of vane 6a. Line 13 supplies air for backflushing of clogged vanes. U.S.A. Specifications 3061477 and 3056504 are mentioned.

Abstract: 1,111,070. Testing coins. EDDY MATCH CO. Ltd. 30 Dec., 1966 [11 Feb., 1966], No. 58267/66. Heading G4V. A coin testing device comprises walls 10, 11 defining a coin passage, a rim gauging means 13 for testing the thickness of a coin at the periphery thereof and body gauging means 15 for testing the thickness of a coin inwardly of the periphery, the rim and body gauging means interlocking to normally hold the body gauging means in a blocking position. The rim gauging means consists of a member 14 pivoted at 25 and having an enlarged head 33 projecting into the coin passage. The head 33 has a centre of curvature 34 and is located opposite an adjustable stud 39. Insertion of a coin having a thickness greater than the spacing between the stud 39 and head 33, pivots the member 14 to release the body gauging means. The latter consists of a pawl 16 pivoted at 24. If the diameter of the coin is less than the spacing between the head 33 and surface 44 of the pawl, the member 14 returns to lock the pawl in its blocking position before the coin reaches the pawl. If the diameter is sufficiently large and the coin is sufficiently heavy, the coin strikes the surface 44 and pivots the pawl to permit the coin to continue down the passage. However, if the thickness of the coin inwardly of the rim is larger than a predetermined amount the coin jams between an extension 17 on the pawl and a bifurcated member 51. The latter is slotted at 55, 56 whereby it may be adjusted in position by screws 54, 57. The member 14 carries a chain 43 to dampen oscillations therein.

Abstract: 1312367 Fancy yarn CHAVANOZ SA 16 Dec 1970 [20 Feb 1970 25 Nov 1970] 59767/70 Headings D1D D1F and D1W A process for the manufacture of a fancy yarn by the false twist assembly of at least two yarns of which at least one is overfed relative to the or each other yarn is characterised by the step of binding the effect yarn obtained by feeding a third yarn with the said two yarns to a twist blocking device where the three yarns are combined. The overfed yarn is called the effect yarn and the third yarn the binding yarn. In operation, a core yarn 101 is taken from a bobbin 102 and fed, preferably through a hollow spindle 104 carrying a package of effect yarn 106, to the hollow rotating spindle 112 of a package 109 of binding yarn 110. An effect yarn 106 is taken from a package 105 on the spindle 104 and overfed, relative to the core yarn, to the spindle 112 carrying the binding yarn. The core yarn 101 and effect yarn 106 are fed through the rotating spindle 112 to a twist blocking device 111. A binding yarn 110 is taken from the package 109 and fed through the rotating spindle 112 to the twist blocking device 111, where the three yarns are combined and the fancy yarn produced is taken up on a package 113. The twist blocking device is fixed to the spindle 112 either at the upstream end or at the downstream end thereof and may comprise one or more grooved rollers 12, 13 around which the yarns pass, see Fig. 2. The rollers 12, 13 may be idler rollers or may be fixed. In a further embodiment, the rollers are replaced by pins. In the case that the twist blocking device is fixed at the upstream end of the spindle 112, a guiding tube is provided around the twist blocking device. The overfeed of the effect yarn is preferably controlled to be regular or irregular, and similarly the take up of the fancy yarn is controlled to be regular or irregular. The yarns used may be of natural, artificial, synthetic or mineral fibres, and may be in the form of continuous filament yarns, spun yarns or rovings. In a further embodiment, the effect yarn is in the form of a ribbon or web of paper or textile material. When a roving is used as the core yarn or the effect yarn it may be fed directly from a drawing frame.
