20060037889 - Apparatus for reclamation of precious metals from circuit board scrap: The present invention springs from the discovery that mild acids could be utilized to shear undesired metals away from desired precious metals that have been plated onto circuit board runners or contacts. This shearing action occurs at a high rate when metal scrap segments are immersed in mild acid and...

20060037888 - Cross circulation mail sorter stacker design with dual ported input, and method of operating the same: A new and improved mail sorting system, which is able to dramatically increase the throughput sorting volume of mail pieces or articles, comprises the incorporation of a plurality of cross-circulation path (CCP) conveyors within a conventional looped or folded conveyor belt system whereby, in effect, mail pieces or articles can...

20060037890 - Environmentally safe promoter for use in flotation separation of carbonates from minerals: An environmentally safe composition of matter for use as a promoter chemical in flotation separation of carbonates from industrial sand is disclosed. The promoter chemical replaces the standard petroleum sulfonate, glycol ether and nonphenol used in promoter chemicals with biodegradable substitutes permitting the waste from flotation separation to be disposed...

20060037891 - Screen assemblies utilizing screen elements retained in perforated troughs: A screen assembly is disclosed for use with vibratory separators. The screen assembly includes a structural frame mounted to a vibratory separator into which a plurality of lightweight and flexible screen elements are inserted into multiple rows of perforated troughs which have geometric shapes. The perforated troughs are bonded to...

20060037892 - Apparatus for optically analyzing products such as fruit having indirect illumination: An apparatus for optically analyzing products such as fruit for automatic sorting, includes a device (1, 2) for conveying the products in a continuous line in a longitudinal direction, at least one station for optically analyzing the external surface of the products, a device for illuminating the products having at...

20060032790 - System and process for break detection in porous elements for screening or filtering: A detector for breaks in screens and filters employed in material separators includes a transmitter of RF signals and a receiver of RF signals located to either side of a screen. The separator includes a chamber having a barrier to RF signals with a path through the barrier being defined...

20060032791 - Screen device: A screen device includes a screen for receiving papermaking raw materials and a stirring member facing an outer surface or inner surface of the screen and rotating to wash a mesh of the screen, so that foreign materials are removed from the papermaking raw materials. The screen includes slits elongated...

20060021916 - Method for the flotation of contaminants from an aqueous fibrous suspension: Method and flotation vessel for removing contaminants from aqueous fibrous suspension. Method includes damming up fibrous suspension at head level above base of flotation vessel, forming a bubble flow of gas bubbles rising counter to field of gravity in dammed up fibrous suspension, and guiding fibrous suspension crosswise to bubble...

20060021917 - Method and apparatus for processing toothbrushes: A method of processing toothbrushes includes supplying a plurality of toothbrushes with tufts of bristles attached to heads of the toothbrushes. Similar portions of each of the toothbrushes differ in color from each other. A color of the portion of each of the toothbrushes is determined. The toothbrushes are reorganized...

20060021918 - Arrangement for separation of particles, and a separation method in connection with a process for manufacturing power cables: The invention relates to an arrangement for separating particles from a flow of pellet-shaped or granular elements that are fed from a source to a subsequent workstation for processing the said elements. The invention is characterized in that the said arrangement comprises a screen arrangement that is arranged downstream of...
