Title: Apparatus for removal of heavy objectionable material from cereal, legumes and otherfood products
IPC: B07B4/08
Filed: 1946-06-17
Abstract: 646,698. Pneumatic separators. SUTTON, STEELE & STEELE, Inc. June 17, 1946, No. 5190/49. Divided out of 646,639. [Class 117] In the separation of a mass of heavy refuse particles and lighter particles in e.g. a mass of cereals or legumes, by feeding the mass from a shoot 18 on to a rapidlyreciprocating pervious inclined deck 2 through which air is forced upwardly as by a fan 24 to effect a preliminary separation of the heavier from the lighter particles, a final separation is effected during flow through a continuously open outlet passageway 5 transversely contracted relatively to the deck 2 by forcing air upwardly into the passageway. The air is caused to flow simultaneously in two directions as by a deflector plate 10 forming the roof of the passageway, the plate being of convex shape so as to deflect the air in opposite directions to force the lighter particles inwardly for discharge at the lower end of the deck and the heavy refuse particles outwardly. A wall 8 at the lower end of the deck is adjustable vertically to predetermine the depth of the bed of particles on the deck. Banking bars or walls 4 extend inwardly from side walls 3 to terminate in the outlet passageway 5. As shown, the deflector plate 10 is pivotally suspended on pivots 15 which are so arranged and the curvature of the plate is such that its underside is disposed nearest the bottom of the passageway at a point adjacent but short of the open outer end thereof. The position of the plate is adjusted by adjusting the balance weights 10b. Alternatively, the weights 10b may be omitted. In another modified form the deflector plate is provided with a convex face which is preferably in the form of an arc of a circle. the plate being secured to a carrier member adjusted vertically by means of a vertical rack and gear wheel. To provide a roughened surface for the deck, it is composed of woven wire having laterally spaced warp strands 41, Fig. 5, crimped over each weft strand 42 to the extent of a semi-circle, the lateral opening of the weft strands being equal to the diameter of the strands. The top surface of the warp strands is roughened by transverse grooves 43. In a modification of the machine suitable for the separation of meats from the hulls of cotton seeds the height of the banking bars 4 is decreased and the height of the walls 3 increased so that they extend above the walls 9. The feed 18 is placed at the lower end of the deck, the lighter particles flowing off over the banking bars 4 at either side of the passageway 5 through which the heavier particles are discharged. Specification 207,094, [Class 117], is referred to.

Abstract: 454,092. Spray carburetters. GREENWOOD, J. H., 33, North Valley Road, Colne, Lancashire. Feb. 19, 1935, No. 5274. [Class 7 (iii)] A rotary fuel valve which is connected to operate simultaneously with separate air and mixture valves remains closed during an extended movement which re-opens the air and mixture valves. Fuel supplied through a passage 8, Fig. 4, past a rotary valve 7 to an adjustable nozzle 2 centrally disposed in a mixing chamber A mixes with air drawn past a valve lla which is connected by a link 16, Fig. 1, with a throttle valve 11. The link 16 carries a bowl 16c engaging in a slot in one arm of a bell-crank lever 17 loosely mounted on the shaft of the valve 7 and adapted to turn that valve through an arm 18 angularly adjustable with respect to the lever by screws 18b. During idling, the second arm of the lever 17 rests, through a screw 21 on an arm 22 to maintain the valves 11, 11a slightly open and additional air traverses a byepass 14, 14a, around the air valve 11a, under control of an adjustable valve 13. The arm 22 is pivoted on a bracket 23 and may be rotated to bring a notch therein beneath the screw 21. This permits the lever 17 to close the fuel valve completely and turn the valves 11, 11a beyond their closed position to allow air only to enter the engine cylinders. Oppositely rotating fans a, b promote mixing of the fuel and air.
