Patent number: 9886752Abstract: Method and apparatus for grading food items, such as shrimps and chicken parts, with an automatically calibrated imaging system. Singulated food items are individually imaged. An estimated weight for each food item is computed from its image and an image-to-weight function. Calibration weighers weigh the food item individually or in batches before or after imaging. The actual weights are compared to the estimated weights to fine-tune the image-to-weight function and improve weight estimation.Type: GrantFiled: February 5, 2016Date of Patent: February 6, 2018Assignee: Laitram, L.L.C.Inventors: Bruce F. Taylor, Robert S. Lapeyre

Patent number: 9622492Abstract: Methods and systems using a vision system to process shrimp. The in-line or off-line vision system captures images of samples of shrimps. The processor produces a digital image of the shrimps in the samples. Shrimps exiting a peeler are imaged to determine the number of tail segments in or the percentage of full weight of each. The shrimps are classified by the number of intact segments, and quality, yield, and throughput computed from the classification results. The processor can control operational settings of the peeler based on the classification results. In a larger system including other shrimp-processing equipment besides the peeler, other points along the processing path can be imaged by camera or sensed by other sensors to determine processing quality and to make automatic operational adjustments to the equipment.Type: GrantFiled: April 22, 2015Date of Patent: April 18, 2017Assignee: Laitram, L.L.C.Inventors: Charles J. Ledet, Robert S. Lapeyre, Bruce F. Taylor

Patent number: 9538769Abstract: System and method for processing raw shrimp. A head-on shell-on shrimp is first back-slit to expose the vein. Next, the head and some or all of the vein is removed in a hydraulic deheader. The headless, back-slit shrimp is then peeled in a roller-type peeling machine to remove the shell and any residual vein and provide high-quality, peeled and deveined shrimp meat.Type: GrantFiled: January 4, 2016Date of Patent: January 10, 2017Assignee: Laitram, L.L.C.Inventors: Lars Vedsted, Bruce F.

Publication number: 20160309728Abstract: A multi-stage grading system and method of grading products. The initial stage comprises a binary grader grading products into a large size and a small size. The small-size products are subsequently graded into a plurality of small-size size grades by a mechanical grader. The large-size products are subsequently separated and graded into a plurality of large-size size grades by a higher precision weight-based grader, such as a vision-based grader or a checkweigher.Type: ApplicationFiled: March 24, 2016Publication date: October 27, 2016Inventors: Charles J.

Patent number: 9420638Abstract: The present invention is directed to an electrode structure which is most applicable for plasticating barrels having wound, wire resistance heaters. Electrode structure includes at least one lower electrode plate and an upper electrode plate. A closely wound electrode band connected to the wound wire resistance heater is formed over the lower electrode plate to assure maximum electrical, and thus, thermal transfer. An upper ceramic layer is formed over the electrode band and wound wire resistance heaters. This upper ceramic layer can be ground down to accommodate the addition of an external plate on top of the upper electrode plate.Type: GrantFiled: August 3, 2012Date of Patent: August 16, 2016Assignee: Nordson CorporationInventors: Bruce E.

Publication number: 20090004318Abstract: A system for supplying processed material includes a barrel for transporting the processed material, having a chamber and an electrically conductive wall enclosing the chamber. The barrel has a length and an outer surface. Thermal insulation extends along at least a portion of the length and around the outer surface and provides an exterior surface whose contour is uniform and formed without grooves. A coil comprising an electric conductor is encased in an electrical insulating sheath. The coil contacts and encircles the exterior surface in loops forming an induction winding that extends along at least a portion of the length and around the exterior surface in a spiral path. An induction power supply is used for supplying alternating current to the coil at a relatively high frequency.Type: ApplicationFiled: June 9, 2008Publication date: January 1, 2009Inventors: Bruce F.

Patent number: 6470294Abstract: The system and method of the present invention determines the rate of application of liquid glue to corrugated board on a corrugator. A sensor employing the principle of infrared absorption measures the amount of water on the surface of the glue roll upstream of the point of application of the glue to the corrugated board's medium. A second sensor employing the principle of infrared absorption measurers the amount of water on the surface of the glue roll downstream of the point of application of the glue to the corrugated board's medium. Using calibration coefficients the two sensor's output signals are then converted into film thickness measurements. The downstream film thickness measurement is then subtracted from the upstream film thickness measurement to compute the reduction in film thickness caused by the intervening application of the glue to the medium.Type: GrantFiled: April 12, 2000Date of Patent: October 22, 2002Assignee: Qualitek-VIB, Inc.Inventor: Bruce F.

Patent number: 5680987Abstract: The apparatus and method of the present invention generates and controls an air-atomized spray, for application of moisture to a moving sheet, such as paper or converted paper products (e.g. corrugated board). The air-atomized water spray is generated by mixing a metered quantity of water with a constant air volume. In a representative embodiment the water flow is metered by adjusting the axial position of a shut-off needle relative to a circular control orifice. The needle is positioned by pushing and pulling upon it with a thermally-expanded metallic element. The thermally expanded element is heated directly or indirectly, at a controlled rate, to produce the desired needle movement and resultant water flow. A series of such controllable nozzles can be mounted across the width of a sheet to permit localized, metered moisture application to each cross-machine control zone.Type: GrantFiled: January 27, 1995Date of Patent: October 28, 1997Assignee: Qualitek LimitedInventor: Bruce F.

Patent number: 5663565Abstract: The system and method of the present invention determines glue-line characteristics, such as temperature, of corrugated board. Components of an on-line glue sensor's output signal that are oscillating at the fluting frequency are isolated. The components of the sensor output signal that are sensitive to glue, which is only present on the tips of the flutes, oscillate at the fluting frequency. Those variations in the sensor output signal that are not oscillating at the fluting frequency are canceled out, while those that are oscillating at the fluting frequency are isolated and amplified, facilitating an accurate estimate of their amplitude. The output signal of an infrared absorption sensor will provide an improved on-line starch measurement for corrugators. The incremental amount of infrared radiation that is absorbed by starch and/or water in the glue-lines is isolated from the predominant, more random background absorption due to cellulose and water in the paper substrate.Type: GrantFiled: May 23, 1995Date of Patent: September 2, 1997Assignee: Qualitek LimitedInventor: Bruce F.
