  • Patent number: 5510610
    Abstract: An algorithm is disclosed which effectively removes the knurled annular portion on the bottom of a glass or plastic bottle which is located at an inspection location where diffused light is shown through the bottom of the bottle and is observed by a camera looking down through the bottle opening. The annular area is unwrapped and differenced to eliminate the knurling so that defects can be defined.

  • Patent number: 5425794
    Abstract: A machine for forming glass containers from discrete gobs of molten glass comprising a mechanism displaceable between retracted and advanced position. A pneumatic actuator having upper and lower chambers controlled by a servo pneumatic valve controller, controls the displacement of the pneumatic actuator. A position lead based upon the actual position of the mechanism is calculated and differenced with a position demand to define a position delta. A position lag is calculated based on the position delta. The pressures within the upper and lower chambers are sensed and based thereon a force representative of the force being applied to the piston is calculated and differenced with the position lag to define a force error and a lag force is calculated based on the force error. The servo pneumatic valve controller is driven with the lag force.

  • Patent number: 5351552
    Abstract: A machine for squeeze testing glass containers comprising a test station, including a fixed pad having a curved container engaging surface and an opposed wheel selectively spaced from the surface, rotating at a predetermined surface speed and in the direction required to roll a container delivered to the station along the curved surface until it is released therefrom. A conveyor delivers containers to the test station and carrys released containers away from the test station. A roller is rotatable about an axis parallel to the axis of rotation of the wheel and defines with the wheel a path through which released containers will pass. The roller is biased forward to a selected location whereat the distance between the roller and the wheel is less than the outer diameter of a released container, and the roller is rotated at a surface speed selected to reduce the rotation of a released container, which passes between the wheel and the roller.
