Title: Calibration arrangement and method for calibrating an inspection instrument
Inventor: KUREK DAVID
IPC: G01N29/30
Filed: 1994-08-08
Abstract: ABSTRACT OF THE DISCLOSURE          Calibration arrangement and method for calibrating an inspection instrument, such as an ultrasonic inspection instrument of the kind typically used to inspect nuclear reactor pressure vessels.   The calibration arrangement comprises a frame, the frame having a slot therethrough for receiving a sonic coupling medium therein.  A plurality of channels extend through the frame and are in communication with the slot.  A plurality of solid reflector rods mating-ly extend through respective ones of the channels and into the slot for reflecting sonic energy produced by a pulsed ultrasonic transducer mounted on the frame and spanning the slot.   A pulser stimulates the transducer so that the transducer  transmits  pulsed  sonic  energy  through  the coupling medium which resides in the slot. The sonic energy is reflected by the rods that pass through the slot. The  reflected sonic energy or echoes are received by the transducer, which generates transducer output signals that are received by a receiver.  The receiver provides analog output signals that are converted by an analog-to-digital converter into digital output signals  A computer connect-ed to the analog-to-digital converter evaluates the digital output signals.  A display is  connected to the computer for viewing the digital output signals.   The digital output signals viewed on the display are therefore indicative of the orientations of the reflector rods in the frame for calibrating the transducer with respect to the orientations of the reflector rods in the frame.

Title: Unscrambling conveyor
Inventor: LOOMER WESTON R
IPC: B65G47/14
Filed: 1995-03-02
Abstract: An unscrambling conveyor includes two side-by-side sets of rollers arranged in a herringbone pattern on either side of a central axis. The rollers of the two sets are positioned at different angles with respect to the axis and the drive speeds for the rollers are chosen to provide equal and opposite forces in the lateral direction and unequal but similarly directed forces in the axial direction. The sets of rollers are divided into zones havingprogressively increasing roller speeds in the downstream direction with the zones are staggered with respect to one another on either side of the central axis. The lateral and axial forces drive articles on the conveyor toward and away from the center axis depending on the roller speeds in the staggered zones and in the downstream direction while imparting a twist to the articles. The successive zones of increasing speed stretch a randomly arranged mass of articles into a single file line. Two unscrambling conveyors may be positioned side-by-side to form a flow splitting-unscrambling conveyor.
