| 141 | Aeration separator | US195719 | 1988-05-18 | US4946044A | 1990-08-07 | John R. Havrilla |
| An aeration separator for separating lighter and heavier materials in a separation chamber in which the material flows through a downwardly sloping passage in the lower region of the separation chamber toward a lower discharge while air flows upwardly through the material to aerate and agitate it to separate the lighter particles and direct them to an upper discharge. | ||||||
| 142 | Method and apparatus for removing veneer from reworked medicine tablets | US681528 | 1984-12-14 | US4565326A | 1986-01-21 | Willard D. Varley |
| The invention is a method and apparatus for removing veneer coating shards from granular, medicinal formulations which are being reworked. The formulation is ground up, sifted to remove the smaller pieces which do not contain veneer shards, and then placed into an air suspension under an inverted funnel-like separator cone. The separator cone has air outlets for the air suspension apparatus, as well as a vacuum inlet, adjacent its upper end. The light veneer shards ride up the sloped walls of the separator cone, and they are sucked into the vacuum inlet, thereby removing them from the granulation. | ||||||
| 143 | Grain cleaning device | US301072 | 1981-09-10 | US4384953A | 1983-05-24 | Wayne Christian |
| A grain cleaning device is provided which separates foreign material from grain by aspiration. The aspiration force is developed by a fan which is attached to the grain cleaning device. The device includes a housing, a grain inlet in said housing, a louvered grain slide located within said housing, an opening within the housing which is compatible with the fan, air intake holes within the housing and adjustable covers for said air intake holes. The grain enters the grain cleaning device through the grain inlet and travels down the louvered grain slide. The fan which is located above the louvered grain slide acts as an aspirator and removes the foreign material from the grain which has a density less than the density of the grain. The foreign materials are drawn up through the fan and out an exhaust vent. The housing includes a grain slide housing and a chimney, the chimney being attached to the top of the grain slide housing. The grain slide and grain inlet are located in the grain slide housing and the fan is attached to the chimney. The grain slide extends from below the grain inlet at an angle to the bottom of the grain slide housing. The grain after being cleaned falls out of bottom of the grain slide housing into a pit, grain elevator skirt, etc. | ||||||
| 144 | Conveying and classifying of particulate substances | US935108 | 1978-08-21 | US4203833A | 1980-05-20 | Heinrich Wagener; Karl-Heinrich van Heek |
| A method and an apparatus are disclosed for classifying particulate substances. A mix of heavier and lighter particles is confined between upwardly divergent side walls and a fluidizing gas is blown into the mix from below. A conveying conduit is arranged below the sidewalls and has vertical conduit portions which have upper open ends communicating with the space between the sidewalls. A classifying gas is blown through the conduit and the conduit portions at a pressure which is higher than that of the fluidizing gas to keep the lighter particles from entering the upper open ends, but which is sufficiently low so that the heavier particles can overcome the pressure of the classifying gas and drop through the upper open ends into the conveying conduit from which they are periodically expelled by bursts of a transporting gas. | ||||||
| 145 | Method of sorting fluidized particulate material and apparatus therefor | US939811 | 1978-09-05 | US4194971A | 1980-03-25 | Jan M. Beeckmans |
| Fluidized particulate material in an elongated fluidizing bed is separated by means of paddles, on an endless chain running around sprockets, urging at least an upper portion of the fluidized bed towards one end of the bed to enrich that end with lighter particles and the other end with heavier particles. The particles thus separated are removed from the ends of the bed by, for example, flowing over weirs. In one embodiment only the paddles passing along the underside of the chain dip into the fluidized bed while in another embodiment the whole chain and all of the paddles are immersed in the fluidized bed. | ||||||
| 146 | Apparatus for purifying a suspension of fibrous material | US927558 | 1978-07-24 | US4190522A | 1980-02-26 | Josef Tra |
| Apparatus for removing impurities entrapped in a suspension of fibrous material includes a fluidized bed chamber having opposite ends, a top wall, and a perforated bottom wall. An inlet feeds the suspension to be purified to a diffusing chamber which imparts laminar flow thereto and, in turn, feeds the suspension to the fluidized bed chamber through one end thereof for flow across the bottom wall toward the other end. A pressure chamber is positioned below the fluidized bed chamber and communicates with the bottom wall thereof, the pressure chamber having a plurality of walls thereacross dividing the same into a plurality of sections. A manifold has branches communicating with each section of the pressure chamber for introducing a fluidizing agent under pressure thereto for upward flow through the perforations in the bottom wall and through the suspension therein thereby to separate impurities from the suspension by flotation. A separation chamber has a forward end communicating the other end of the fluidized bed chamber for receiving the suspension therefrom and has top and bottom walls and a rear wall. A light impurities withdrawal conduit extends upwardly from the top wall of the separation chamber in the forward region thereof for removing separated impurities from the suspension which have relatively low specific gravity and float to the top thereof. A fibrous suspension withdrawal conduit extends from the rear upper region of the separation chamber for removing the purified fibrous suspension therefrom, and a heavy impurity withdrawal conduit extends from the lower region of the separation chamber for removing separated impurities from the suspension which have relatively high specific gravity and settle to the bottom wall of the separation chamber. | ||||||
| 147 | Apparatus for use in producing a fluidized bed of granular material | US805444 | 1977-06-10 | US4146466A | 1979-03-27 | Roland P. Chapman |
| A fluidizing tank for granular refractory material has a porous bottom wall that is displaceable downwardly from a bottom edge of the tank in order to define a gap through which contaminating precipitated particles can fall from the tank, preferably aided by a downward slope of the porous wall. A receptacle housing the tank contains a vibratory sieve for separating the particles from the material falling from the tank so that the sieved material may be returned to the tank, preferably directly by mechanical or suction transfer from the bottom of the receptacle. | ||||||

| A process and system for the segregation and separation of mixed office-paper-waste material which comprises: shredding the waste material to a uniform size; forming a fluidized bed of the shredded waste material in a vertical column by an upwardly flowing, high-volume, low-pressure air stream, to divide the material into distinct layers in the column; and separating and removing the layers from the column with lateral airflow. | ||||||
| 149 | Apparatus and method for particle separation and grading | US707446 | 1976-07-21 | US4115256A | 1978-09-19 | Hotze Jan DE Zeeuw |
| Apparatus and method for separating fly ash into its major constituents; namely, metal, carbon black, cenospheres and dust. The metal is separated by passing the fly ash through a magnetic field at least a part of which has an alternating polarity. The non-magnetic constituent is separated into conductive and dielectric constituents with a high tension separator and the conductive constituent, chiefly cenospheres, is then graded by size. The grading is effected by passing the non-magnetic, conductive fly ash constituent through a cross-flow of ionized air which suspends the cenospheres at different levels according to their weight and size. The apparatus and method has general utility, with obvious modifications, to the grading of particles other than cenospheres. | ||||||
