Abstract: A system and process for sorting and conveying articles consisting of discarded tires and debris from one site to another site. The system and process receives articles in bulk, and concurrently singularizes and conveys the separated articles. Various physical characteristics of the individual articles, such as weight and size, are determined as the articles are continuously conveyed. Those articles having a physical property outside of a predetermined parameter range are ejected from the system. The remaining articles are then accumulated into groups of articles based on a physical characteristic of each article such that the sum of the physical characteristics of the articles of each group will be above a minimum and not exceed predetermined maximum values. The group of articles is then conveyed as a unit out of the system for a following operation such as disposal of the articles.

Abstract: An automatic article stacking system wherein a plurality of articles to be stacked are arranged in layers prior to being stacked. The layers are advantageously arranged horizontally orthogonal to one another so as to enhance the stability of the stack. A measurement system is provided for determining whether any of the articles exceeds a predetermined size limit. In one embodiment which is arranged for stacking egg cartons, a determination that the egg carton exceeds the predetermined size limit signifies that the egg carton is open and, therefore, not in a form suitable for stacking. The open egg carton is conveyed under an elevator which accumulates the articles to be stacked, and to a discharge area. Thus, closed egg cartons are accumulated in layers and stacked. Successive layers of articles are stacked under prior stacked layers.

Abstract: A method of and apparatus for sorting pieces or particles of radioactive ore where the particles are moved one after another substantially horizontally then discharged into a gravity-accelerated trajectory which is substantially free-fall but can be controlled to follow a modified path by a low-friction slide plate. The falling particles pass a plurality of radiation detectors arranged in line along their path with increasing velocity due to gravity providing the required separation of the pieces so that each detector is subject to the radiations of essentially only one piece at a time. The size and number of detectors and the path length covered by the detectors is determined by the size of the pieces and the cut-off grade and accuracy required. All counts corresponding to a particular piece and derived successively from the plurality of detectors are accumulated since accuracy increases and percentage of probable error decreases with increased total count.

Abstract: Apparatus for inspecting nuclear fuel pellets in a sealed container for diameter, flaws, length and weight. The apparatus includes, in an array, a pellet pick-up station, four pellet inspection stations and a pellet sorting station. The pellets are delivered one at a time to the pick-up station by a vibrating bowl through a vibrating linear conveyor. Grippers each associated with a successive pair of the stations are reciprocable together to pick up a pellet at the upstream station of each pair and to deposit the pellet at the corresponding downstream station. The gripper jaws are opened selectively depending on the state of the pellets at the stations and the particular cycle in which the apparatus is operating. Inspection for diameter, flaws and length is effected in each case by a laser beam projected on the pellets by a precise optical system while each pellet is rotated by rollers.

Abstract: A method and apparatus for grading and sorting articles, particularly fruit, according to size, surface blemish and surface color. Fruit is passed sequentially through a camera array which scans the surface of each fruit and measures the intensity of light reflected from successive discrete surface segments. Significant differences between such measured intensities are detected and a measurement of surface blemish is generated in accordance therewith. Size measurements are derived by counting the total number of segments in the surface of each fruit. Color measurements are derived by averaging the ratio of red light intensity to infrared light intensity reflected from each of a plurality of surface areas of each fruit. The fruit are separated and delivered to separate receivers by a mechanism responsive to the size, blemish and color measurements of the respective fruit.

Abstract: A method of and apparatus for sorting pieces or particles of radioactive ore where the particles are moved through the apparatus in an asynchronous or non-constant manner. The particles are moved one at a time to a position in front of a radiation detector where they are temporarily stopped. The counts from the particle are accumulated with respect to time. In a control unit of the apparatus there is data representing a cut-off grade radiation rate and early upper and lower decision limits are established with regard to the cut-off rate. As soon as the accumulated count/time ratio from the detector exceeds the upper limmit or falls below the lower limit, the control unit is able to provide a decision to accept or reject the particle. If the particles are not closely sized then the size of each particle is determined before it is positioned in front of the radiation detector and the size determination is used to modify the cut-off grade and upper and lower early decision limits.

Abstract: Apparatus for sorting items, such as peeled whole potatoes, which, in the absence of abnormalities, exhibit a substantially uniform light reflectivity, includes an illumination chamber through which the items to be sorted are passed successively as a stream. Light sensors are focused on a cross-sectional slice of the illumination chamber through which the items pass, each of these light sensors being focused on only a small portion of the slice. Electronic circuitry in conjunction with the light sensors counts the number of such sensors sensing abnormalities. If the number of sensors sensing abnormalities is greater than a predetermined minimum, a reject signal is produced. If desired, the circuitry may be arranged to also determine whether the number of sensors sensing abnormalities is greater than a predetermined percentage, for example, 50%, of the total number of sensors sensing the item, and thus produce a second reject signal if the abnromalities make up more than the predetermined percentage.

Abstract: To enable a high-speed machine to process (for instance interconnect and reel) only acceptable, predeterminedly ordered electronic components after appropriate test, velocity changing mechanism actuatable by a continuously operable conveyor of the machine is provided to shift components to and from a testing unit and relative to their respective successive locations along the conveyor. Only failure of a component to qualify at the test unit automatically stops the conveyor, and that enables an operator to take corrective action by satisfactory completion of a test on a replacement component which then is preferably manually located in its proper sequence on the conveyor prior to re-starting of the machine. Accordingly, except for the usually uncommon short interval when an attendant may need to make substitution for an unsatisfactory component which has been detected, the invention enables rapid processing of assuredly reliable components and their intended sequence is verified.
