  • Patent number: 4707138
    Abstract: A color detecting device comprising a head (14) supported on an arm (30) for oscillatory motion over the product (11) being color measured to render a signal responsive to the average color of the product. A height detector (44) provides a signal indicating the distance between the product and head and is used to modify the color signal accordingly. A temperature sensor (39) in the head indicates an overtemperature condition for causing movement of the head away from the product. The screen (17) transparency is measured by the indicator (47, 48) to indicate when the screen is dirty.

  • Patent number: 4509414
    Abstract: An apparatus for removing appendages (10A) from articles or produce (10) comprising a first conveyor (12) carrying a plurality of pairs of counter-rotating rolls (16) and (17) for movement along an inclined section (14). The articles are introduced through a chute (15) to roll down the inclined section with the appendages being caught and pulled therefrom by the counter-rotating rolls. A second conveyor (60) carries plows (71) to contact and regulate the dwell time of the articles on the pinch rolls. The dwell time can be regulated by changing the speed of the first and second conveyors and the inclination of the first conveyor. A waste tray (48) catches the removed appendages and blades (49) carried on the bottom side of the first conveyor move the waste debris from the waste tray.
