20080264837 | CHROMATOGRAPHY COLUMN WITH PACK, UNPACK, AND CLEAN-IN-PLACE FEATURES - A preparative chromatography column is equipped with one or more valves that can each be used to both inject a column packing into the column or withdraw used packing from the column, in addition to cleaning the supply and discharge lines associated with the valve itself, all by moving a movable plug within the valve body and all without protruding into the column interior. Each valve is mounted on the lateral wall of the column just above the filter plate at the column floor, and the plug is movable between a closed position in which the end surface of the plug is flush with the inner wall of the column and an open position in which the plug is recessed within the bore. Each valve has two additional ports in its valve body, positioned such that when the plug is closed, both ports are open to the valve bore, and when the plug is open, at least one of the ports is open to the bore. The position of the plug within the valve bore determines the valve function. | 10-30-2008 |
20090071881 | Method for Production of Bulk Concentrate for Extracting Precious Metals - This invention relates to methods for producing bulk concentrate for precious metal recovery from clay-salt residues of plants processing potassium-magnesium ore and rock salt, usable for recovery of components in the form of sedimentary and floated particles, wherein the liquid phase comprises components varying in solubility and density. The method is cost-effective and includes a three-stage hydro-cycloning applied to slimes with S:L=1:3 ratio, carried out sequentially via 10, 7, and 5 degree hydro-cyclones. The bulk concentrate is mixture of sedimentary and floated materials, insoluble in water slimes residue. The second hydro-cyclone discharge, being a salt solution and floated part of the residue with natural and artificially-made organic structure, is forwarded to the third hydro-cyclone for extracting the floated fraction via a discharge fitting and further mixing with concentrates of the first and second hydro-cyclones, formation of the bulk concentrate. The salt solution is extracted via a sand fitting. | 03-19-2009 |
20100044282 | DEFLECTOR DEVICE FOR COAL PIPING SYSTEMS - A deflector device for improving particle distribution within a coal piping system includes a base defining an outer circumference. The base is configured to be mounted inside a pipe such that the base extends partially around the inner circumference of the pipe with the circumferences of the pipe and base being substantially aligned concentrically. A deflector extends radially inward from the base. The deflector is configured to direct a concentrated flow of coal particles toward the center of the pipe. | 02-25-2010 |
20120248013 | Eddy Current Separator - An eddy current separator (“ECS”) separates electroconductive and non-electroconductive materials. The materials can include “fines” having diameters less than about 10 millimeters. The ECS includes first and second hubs coupled to opposite ends of a magnet support tube. Magnets are coupled to the magnet support tube, substantially between the hubs. A motor coupled to one or both of the hubs rotates the magnet support tube and magnets to generate an eddy current in electroconductive material conveyed proximate the separator. The material in which the eddy current is created is repelled and projected away from the ECS along a predictable trajectory. An eddy current is not generated in nonconductive material conveyed proximate the separator. Therefore, that material is not projected away. A jacket tube may house the magnets and contain centrifugal forces of the magnets during rotation thereof That tube may comprise a Ti60 titanium alloy or other material. | 10-04-2012 |

20080290006 | Systems and methods for optimizing a single-stream materials recovery facility - Systems and methods for sorting a plurality of recyclable items in a single-stream materials recovery facility (SSMRF) are provided. In some embodiments, a system includes an infeed conveying system, a fiber transfer conveyor, a container transfer conveyor, and a glass sorting and conveying system. The system further includes a controller configured to obtain total weight and volume of recyclable items at the infeed conveying system. The controller estimates a percent weight of fiber items and a percent weight of non-fiber items relative to the total weight. Based on the estimates, the controller controls speed of at least one of the infeed conveying system, the fiber transfer conveyor, the container transfer conveyor, and the glass sorting and conveying system. | 11-27-2008 |
20090101548 | Method of Sorting Postal Items in Flip/Flop Mode - A method of sorting postal items for preparing postman's walks on a postal sorting machine having an inlet and a set of sorting outlets includes loading a first batch of postal items and a second batch of postal items consecutively into the inlet of the machine, and directing the postal items of the first batch towards a first subset of sorting outlets, and the postal items of the second batch of postal items towards a second subset of sorting outlets that is separate from the first subset of sorting outlets; and while the postal items of the second batch of postal items are being directed towards the second subset of sorting outlets, reloading the inlet of the machine with the postal items taken from the first subset of sorting outlets, and, while the postal items of the first batch of postal items are being directed towards the first subset of sorting outlets, re-loading the inlet of the machine with the postal items taken from the second subset of sorting outlets. | 04-23-2009 |
20090206014 | Memory Module for Flat Objects - A storage module for flat articles, has a storage region for a stack of articles, an introduction unit for the introduction of articles from an article stream into the storage region, and a draw-off unit arranged at the same end of the stack as the introduction unit, for drawing off articles from the storage region. The storage module has a movement device for moving the stack away from the introduction unit toward the draw-off unit. The storage module thus provides for an intermediate storage of the articles, which is protective of the mail items. | 08-20-2009 |

20110100884 | DE-INKING SCREEN WITH AIR KNIFE - A material separation system includes a separation screen and an air directing device positioned above the separation screen. The separation screen has at least one rotating shaft, wherein the separation screen transports the relatively rigid material and relatively flexible material to the rotating shaft. The air directing device directs air towards the separation screen such that the relatively flexible material is blown beneath the rotating shaft in a first material stream, wherein the relatively rigid material continues on the separation screen past the rotating shaft in a second material stream. | 05-05-2011 |
20130175207 | Oversized Material Removal System and Method - A material removal system for removing oversized materials from a material stream. This material removal system comprises a first transfer system that is used to transport a material stream, a pulley separator, and a gap that is at least as small as the length of the oversized materials that are to be removed from the material stream. Moreover, the pulley separator comprises a rotatable outer shell that has a tubular width and circular cross-section. The pulley separator is located at a discharge end of the first transfer system to create a gap that is at least as small as the length of the oversized materials to be removed. | 07-11-2013 |

20110297591 | CONVEYOR SYSTEM FOR SEPARATING MIXED RECYCLED MATERIALS - A conveyor system for separating mixed recycled materials containing lighter and heavier recycled materials employs an inclined conveyor belt with a series of rows of rotating beaters striking the underside of the conveyor belt. A feeder mechanism deposits mixed recycled materials onto the midsection of the conveyor belt. Heavier recycled materials are bounced from the conveyor belt and tumble to the lower end, while lighter recycled materials are carried by motion of the conveyor belt to its upper end. | 12-08-2011 |
