Publication number: 20100264070Abstract: 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 to 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.Type: ApplicationFiled: June 29, 2010Publication date: October 21, 2010Applicant: SPECTRAMET, LLCInventors: Edward J. Sommer, JR., David B. Spencer, R. Lynn Conley, Richard E. Hill, Robert H. Parrish, Charles E. Roos

Publication number: 20100219109Abstract: Disclosed herein is the use of differences in x-ray linear absorption coefficients to process ore and remove elements with higher atomic number from elements with lower atomic numbers. Use of this dry method at the mine reduces pollution and transportation costs. One example of said invention is the ejection of inclusions with sulfur, silicates, mercury, arsenic and radioactive elements from coal. This reduces the amount and toxicity of coal ash. It also reduces air emissions and the energy required to clean stack gases from coal combustion. Removal of said ejected elements improves thermal efficiency and reduces the pollution and carbon footprint for electrical production.Type: ApplicationFiled: February 25, 2010Publication date: September 2, 2010Inventors: Charles E.

Publication number: 20100111252Abstract: 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.Type: ApplicationFiled: October 26, 2009Publication date: May 6, 2010Applicant: Spectramet, LLCInventors: Edward J.

Patent number: 7286634Abstract: A method and apparatus are disclosed for screening articles such as baggage, utilizing a computerized touch sensitive screen or other computerized pointing device for operator identification and electronic marking of objects within the article to be further examined. Baggage is electromagnetically scanned while traveling on a conveyer and an electronic image is taken of each article and stored in a computer. The present system utilizes a plurality of visual display devices, each with an examiner, which are likely located remotely of the screening operation. Each examination continues independently of the scanning such that there is no interruption in the flow of articles should an examiner detect an object of interest and worthy of further examination, either by screen or by physical examination.Type: GrantFiled: September 10, 2004Date of Patent: October 23, 2007Assignee: Select Technologies, LLCInventors: Edward J.

Patent number: 7244941Abstract: A method and apparatus for screening articles utilizing a plurality of operators, with each operator utilizing an interactive display to identify and electronically mark objects within an article to be further examined. An operator positioned at an interactive display views electronic images of an article to be screened after it has been conveyed past a sensor array which transmits sequences of images of the series either directly or through a computer to the interactive display. The operator selects objects within the article displayed on the screen for further examination using the interactive feature of the display thereby registering the objects selected within the computer. The computer then provides sequential information identifying actions to be taken and information and data to be recorded.Type: GrantFiled: March 14, 2006Date of Patent: July 17, 2007Assignee: National Recovery Technologies, Inc.Inventors: Charles E.

Patent number: 6610981Abstract: Method and apparatus for sorting plastic materials on a recycling operation wherein near and infrared energy illuminates particles of flake plastic including such as PET, PVC and PS transported along a conveyer line and the contaminant ingredients are identified and ejected from the stream of preferred particles. More accurate sorting, and thus a higher quality sort may be performed where the contaminant materials and the preferred materials are identified by comparing ratios of levels of signals of energy transmitted through or reflected from the particles, the levels of signal being obtained by filtering the energy from the particles through bandpass filters, one filter of which is centered on the absorptive peak of a contaminant and another filter is centered on a frequency exhibiting the energy level of the preferred material equal to that occurring at the center of the filter for the contaminant absorptive peak.Type: GrantFiled: April 24, 2001Date of Patent: August 26, 2003Assignee: National Recovery Technologies, Inc.Inventor: Edward J.

Patent number: RE40394Abstract: A method and apparatus are disclosed for classifying materials utilizing a computerized touch sensitive screen or other computerized pointing device for operator identification and electronic marking of spatial coordinates of materials to be extracted. An operator positioned at a computerized touch sensitive screen views electronic images of the mixture of materials to be sorted as they are conveyed past a sensor array which transmits sequences of images of the mixture either directly or through a computer to the touch sensitive display screen. The operator manually “touches” objects displayed on the screen to be extracted from the mixture thereby registering the spatial coordinates of the objects within the computer. The computer then tracks the registered objects as they are conveyed and directs automated devices including mechanical means such as air jets, robotic arms, or other mechanical diverters to extract the registered objects.Type: GrantFiled: November 3, 1997Date of Patent: June 24, 2008Assignee: National Recovery Technologies, Inc.Inventors: Charles E.

Patent number: RE36537Abstract: An automated interrupt driven system which employs a circular buffer is used to sort materials based on differing electromagnetic radiation absorption and penetration characteristics. The system has a conveyor and a source of electromagnetic radiation which radiates materials travelling along the conveyor. A controller samples detector outputs at various times to evaluate the absorption and penetration characteristics of the materials to be sorted, based on a plurality of samples. Portions of the materials are ignored to obtain accurate readings from the detectors. Based on the detected penetration and absorption characteristics, the controller activates ejection mechanisms causing materials of different compositions to be deposited into different bins. The controller executes interrupts to cause detection, ejection, testing, and system history maintenance at required times.Type: GrantFiled: February 18, 1997Date of Patent: February 1, 2000Assignee: National Recovery Technologies, Inc.Inventors: Edward J. Sommer, Jr., Michael A. Kittel, James R. Peatman
