Inspecting rims of glass containers for crizzle and line-over-finish defects

Claim 1

AN APPARATUS FOR INSPECTING THE RIM OF AN OPEN MOUTH CONTAINER MADE OF TRANSLUCENT MATERIAL FOR CRIZZLE AND LINE-OVER-FINISH DEFEATS COMPRISING A SUPPORT FOR THE CONTAINER, A SOURCE OF RADIANT ENERGY MOUNTED ADJACENT THE CONTAINER, MEANS FOR FOCUSING A BEAM OF RADIATION FROM SAID SOURCE AND DIRECTING THE BEAM AGAINST THE INTERIOR WALL SURFACE OF THE RIM OF THE CONTAINER AT AN ACUTE ANGLE TO A RADIAL PLANE TO PRODUCE A SPOT OF RADIANT ENERGY ON THE RIM OF THE CONTAINER, MEANS FOR ROTATING SAID CONTAINER RELATIVE TO SAID SPOT ABOUT THE AXIS OF THE CONTAINER TO CAUSE SAID SPOT TO SCAN THE RIM OF THE CONTAINER, A FIRST ELEMENT SENSITIVE TO SAID RADIATION MOUNTED ADJACENT SAID CONTAINER WITH ITS LINE OF VISION EXTENDING THROUGH THE OUTER WALL SURFACE OF THE RIM OF THE CONTAINER AND FORMING AN ANGLE RANGING FROM 75 DEGREES TO 105 DEGREES WITH THE PATH OF THE BEAM TOWARD THE RIM OF THE CONTAINER SO THAT A CRIZZLE DEFECT MOVING INTO THE SPOT CAUSES A REFLECTION OF A PORTION OF THE BEAM TOWARD SAID FIRST ELEMENT, MEANS FOR RESTRICTING THE FIELD OF VISION OF SAID FIRST SENSITIVE ELEMENT TO THE AREA OF THE RIM ONTO WHICH THE SPOT OF RADIANT ENERGY IS FOCUSED, A SECOND ELEMENT SENSITIVE TO SAID RADIATION POSITIONED ADJACENT THE CONTAINER WITH ITS LINE OF VISION EXTENDING THROUGH THE OUTER WALL SURFACE OF THE RIM OF THE CONTAINER AND FORMING AN ANGLE RANGING FROM 125 DEGREES TO 175 DEGREES WITH THE PATH OF THE BEAM TOWARD THE RIM OF THE CONTAINER SO THAT A LINE-OVER-FINISH DEFECT MOVING INTO THE AREA OF THE SPOT CAUSES A PORTION OF THE BEAM TO BE REFRACTED AND REFLECTED TOWARD SAID SECOND SENSITIVE ELEMENT, AND MEANS FOR RESTRICTING THE FIELD OF VISION OF THE SECOND SENSITIVE ELEMENT TO THE AREA OF THE RIM OF THE CONTAINER INTO WHICH THE SPOT OF RADIANT ENERGY IS FOCUSED.

Claim 2

AN APPARATUS FOR INSPECTING THE RIM OF AN OPEN MOUTH CONTAINER MADE OF TRANSLUCENT MATERIAL FOR CRIZZLE AND LINE-OVER-FINISH DEFEATS COMPRISING A SUPPORT FOR THE CONTAINER, A SOURCE OF RADIANT ENERGY MOUNTED ADJACENT THE CONTAINER, MEANS FOR FOCUSING A BEAM OF RADIATION FROM SAID SOURCE AND DIRECTING THE BEAM AGAINST THE INTERIOR WALL SURFACE OF THE RIM OF THE CONTAINER AT AN ACUTE ANGLE TO A RADIAL PLANE TO PRODUCE A SPOT OF RADIANT ENERGY ON THE RIM OF THE CONTAINER, MEANS FOR ROTATING SAID CONTAINER RELATIVE TO SAID SPOT ABOUT THE AXIS OF THE CONTAINER TO CAUSE SAID SPOT TO SCAN THE RIM OF THE CONTAINER, A FIRST ELEMENT SENSITIVE TO SAID RADIATION MOUNTED ADJACENT SAID CONTAINER WITH ITS LINE OF VISION EXTENDING THROUGH THE OUTER WALL SURFACE OF THE RIM OF THE CONTAINER AND FORMING AN ANGLE RANGING FROM 75 DEGREES TO 105 DEGREES WITH THE PATH OF THE BEAM TOWARD THE RIM OF THE CONTAINER SO THAT A CRIZZLE DEFECT MOVING INTO THE SPOT CAUSES A REFLECTION OF A PORTION OF THE BEAM TOWARD SAID FIRST ELEMENT, MEANS FOR RESTRICTING THE FIELD OF VISION OF SAID FIRST SENSITIVE ELEMENT TO THE AREA OF THE RIM ONTO WHICH THE SPOT OF RADIANT ENERGY IS FOCUSED, A SECOND ELEMENT SENSITIVE TO SAID RADIATION POSITIONED ADJACENT THE CONTAINER WITH ITS LINE OF VISION EXTENDING THROUGH THE OUTER WALL SURFACE OF THE RIM OF THE CONTAINER AND FORMING AN ANGLE RANGING FROM 125 DEGREES TO 175 DEGREES WITH THE PATH OF THE BEAM TOWARD THE RIM OF THE CONTAINER SO THAT A LINE-OVER-FINISH DEFECT MOVING INTO THE AREA OF THE SPOT CAUSES A PORTION OF THE BEAM TO BE REFRACTED AND REFLECTED TOWARD SAID SECOND SENSITIVE ELEMENT, AND MEANS FOR RESTRICTING THE FIELD OF VISION OF THE SECOND SENSITIVE ELEMENT TO THE AREA OF THE RIM OF THE CONTAINER INTO WHICH THE SPOT OF RADIANT ENERGY IS FOCUSED.
