| Number | Title | Issue Date |
| 7296687 | Methods of separating feed materials using a magnetic roll separator Methods include separating feed material containing magnetic particles and non-magnetic particles using a belt and magnetic roll separator that has an idler roll and a magnetic roll carrying magnets and the methods involve positioning a feed pan or slide for directi... | 11/20/2007 |
| 7267233 | In-line classifier for powdered products A classifier for classifying particulates entrained in a flowing stream of gas is configured such that a change of direction of gas flow causes particles to impinge upon a target, heavier particles being trapped in a downwardly extending fluidized trap. The classifi... | 09/11/2007 |
| 7128216 | Closed air circulation system The invention relates to a closed air circulation system for an apparatus used for sorting wood chips, containing chips in a variety of sizes and/or fines particles, in a wood chips processing chamber, in separate fractions by means of a gas flow, which is delivered... | 10/31/2006 |
| 5271506 | Apparatus for separating fruits or vegetables from debris An improved apparatus for sorting agricultural products such as vegetables or fruits from dirt clods, rocks, or other debris, without bruising the desired product. The mixture of desired product and undesired debris is transported by conveyor and allowed ... | 12/21/1993 |
| 4744470 | Apparatus for separating agricultural produce from spurious matter Apparatus for separating a mixture of agricultural products and stones including an impact element defining an impact surface, which element is operative to absorb appreciable kinetic energy from stones but to absorb a significanty lower amount of kinetic... | 05/17/1988 |
| 4572378 | Separation method and apparatus Apparatus and method for separating discrete items of different materials from a mixture. The mixed items fall vertically from a feeder device onto a plate spinning about a vertical axis. According to their difference in material, the items rebound with d... | 02/25/1986 |
| 4324336 | Separating apparatus An apparatus for separating objects of a particular kind from other objects, e.g. stones etc. from potatoes during harvesting, wherein the objects fall in a stream past a detector for objects of said particular kind and, after detection of an object, a se... | 04/13/1982 |
| 4281766 | Method and apparatus for sorting bodies of different densities To sort first bodies from a mixture of first and second bodies in which the first bodies, for example potatoes or other root crop, are less dense than the second bodies, for example stones harvested simultaneously with the root crop, the mixture is droppe... | 08/04/1981 |
| 4267930 | Raisin separating device A batch of raisins in which moldy raisins are mixed with sound ones is immersed in a hot water bath, causing the moldy raisins to assume a mushy and sticky texture while leaving the texture of the sound raisins substantially unaffected. The batch of raisi... | 05/19/1981 |
| 4162011 | Apparatus for sorting fruits and vegetables Apparatus for sorting firm whole fruits and vegetables from those which are soft and broken by sliding or rolling the specimens to be sorted down an inclined plane to impart momentum and velocity and then dropping them on a rearwardly moving conveyer belt... | 07/24/1979 |
| 4141450 | Method and apparatus for sorting mixtures of materials by ballistic effect and differential adherence The sorting method includes moving materials at a certain horizontal speed such that on falling their points of impact are disbursed over a moving sorting belt in such a manner that the materials become located at points which are sufficiently different t... | 02/27/1979 |
