  • Patent number: 6371275
    Abstract: A dual entry-double helix spiral delivery chute is provided which includes two spiral delivery chutes nested one above the other and being aligned with the same vertical axis. The two chutes are substantially identical in that they provide the same footprint as a single chute. Each chute, moreover, in addition to having an output port includes a top entry port and a side entry port downstream of the top entry port so that each chute can be served by two or more separate sorting machines receiving items from one or more separate sources.

  • Patent number: 6285034
    Abstract: An inspection system for evaluating rotationally asymmetric workpieces for conformance to configuration criteria having a track for causing the workpieces to translate through a test section, the test section including a plurality of electromagnetic energy sources, the plurality of electromagnetic energy sources oriented with respect to the track means such that the workpieces occlude the plurality of electromagnetic energy sources upon passing through the test section, the test section further having electromagnetic energy detectors for receiving the electromagnetic energy to provide output signals related to the intensity of the occluded electromagnetic energy incident on the electromagnetic energy detectors, and a signal processing means for receiving said output signals.

  • Patent number: 6252661
    Abstract: An inspection system for evaluating workpieces for conformance to configuration criteria including a track for causing workpieces to translate through a test section, the test section including a light source for production of a uniform sheet of light, the light source oriented with respect to the track means such that the workpieces occlude the uniform sheet of light upon passing through the test section, the test section further having a video system for receiving the occluded uniform sheet of light, providing output signals related to the intensity of the occluded uniform sheet of light incident on the video system, and a signal processing means for receiving the output signals.

  • Patent number: 5568263
    Abstract: An improved non-contact inspection system capable of evaluating spatial form parameters of a workpiece to provide 100% inspection of parts in production. The system causes parts to be sequentially loaded onto an incline track where they pass through a test section. The test section includes a length detection array for measuring the length of the workpiece, which includes a source generating a sheet of light oriented in the longitudinal direction of the workpiece. The profile of the parts are evaluated by one or more light sources also creating a sheet of light oriented transverse to the longitudinal axis of the parts. First and second pairs of single channel photodetectors are provided for each of the light sources which provides a pair of analog outputs of the extent to which each sheet of light is occluded by the part, as well as an ability to eliminate noise or scintillation caused by a point source of light, for example with a laser light source.

  • Patent number: 4831251
    Abstract: An optical device for discriminating threaded workpiece by the handedness by their screw thread profiles. The device presents a pair of light beams which pass generally tangent to the workpiece at angularly displaced positions. The light beams are inclined to follow the helix direction of a given handedness of a workpiece. Upon axial advancement of a workpiece through the device, a chopped output from the photodetectors indicates that the handedness of the threads matches the inclination of the light beams. The oppositely threaded workpiece, however, provides a generally constant DC output. With appropriate signal processing electronics, an automatic system for discriminating workpieces by thread handedness is provided.

  • Patent number: 4204480
    Abstract: In a shelving system having both vertical and oblique supports for removable shelves, identical shelves are interchangeably usable on either support by virtue of special tabs which are engageable with support slots in two possible ways. The same shelf, therefore, can be mounted horizontally on either the vertical or the oblique supports.
