  • Patent number: 9956609
    Abstract: According to some aspects, a system for producing a target molten metal composition is provided. The system includes a sorting device that sorts input pieces of metal based on a control signal. Sorted pieces of metal are melted in a furnace, and a sensor measures the composition of molten metal in the furnace and in response generates a control signal that is sent to the sorting device.

  • Patent number: 8861675
    Abstract: Disclosed herein is a metal sorting device including an X-ray tube, a dual energy detector array, a microprocessor, and an air ejector array. The device senses the presence of samples in the x-ray sensing region and initiates identifying and sorting the samples. After identifying and classifying the category of a sample, at a specific time, the device activates an array of air ejectors located at specific positions in order to place the sample in the proper collection bin.

  • Patent number: 8855809
    Abstract: Systems for sorting materials, such as those made of metal, are described. The systems may operate by irradiating the materials with x-rays and then detecting fluoresced x-rays, transmitted x-rays, or both. Detection of the fluoresced x-rays may be performed using an x-ray fluorescence detector array. The systems may be configured to provide high throughput sorting of small pieces of materials.

  • Publication number: 20130264249
    Abstract: A piece of material that includes low-Z elements is classified based on photonic emissions detected from the piece of material. Both XRF spectroscopy and OES techniques, for example, Laser-Induced Breakdown Spectroscopy (LIBS) and spark discharge spectroscopy, may be used to classify the piece of material. A stream of pieces of material are moved along a conveying system into a stimulation and detection area. Each piece of material, in turn, is stimulated with a first and second stimulus, of a same or different type, causing the piece of material to emit emissions, for example, photons, which may include at least one of x-ray photons (i.e., x-rays) and optical emissions. These emissions then are detected by one or more detectors of a same or different type. The piece of materials is then classified, for example, using a combination of hardware, software and/or firmware, based on the detected emissions, and then sorted.

  • Patent number: 8553838
    Abstract: A system and process for classifying a piece of material of unknown composition at high speeds, where the system connected to a power supply. The piece is irradiated with first x-rays from an x-ray source, causing the piece to fluoresce x-rays. The fluoresced x-rays are detected with an x-ray detector, and the piece of material is classified from the detected fluoresced x-rays. Detecting and classifying may be cumulatively performed in less than one second. An x-ray fluorescence spectrum of the piece of material may be determined from the detected fluoresced x-rays, and the detection of the fluoresced x-rays may be conditioned such that accurate determination of the x-ray fluorescence spectrum is not significantly compromised, slowed or complicated by extraneous x-rays. The piece of material may be classified by recognizing the spectral pattern of the determined x-ray fluorescence spectrum. The piece of material may be flattened prior to irradiation and detection.
