Abstract:
METHODS OF COATING IRREGULARLY SHAPED ARTICLES AND OF SHADING THE EDGES OF ARTICLES ARE PERFORMED AUTOMATICALLY USING A SENSOR THAT MOVES WITH THE COATING APPARATUS TO GENERATE A CONTROL SIGNAL FOR THE COATING APPARATUS. WHERE THE SENSITIVE AREA OF THE SENSING MEANS IS NOT CO-EXTENSIVE WITH THE COATING ZONE OF THE COATING APPARATUS, THE CONTROL SIGNAL IS STORED IN A MEMORY MEANS SYNCHRONIZED WITH THE COATING APPARATUS. THE RECORDED SIGNAL IS DETECTED TO OPERATE THE COATING APPARATUS OVER THE APPROPRIATE PORTION OF ITS PATH OF MOVEMENT WHEN THE ARTICLES TO BE COATED IS WITHIN THE COATING ZONE OF THE COATING APPARATUS.
Abstract:
A condition responsive material flow control valve that reacts to the occurrence of the condition to terminate material flow through the valve. The valve is designed to activate only when the condition exists. The valve may be responsive to a condition such as exceeding a predetermined elevated temperature; the presence of such an elevated temperature causes adjacent body members to separate and a ball valve to engage with a valve seat so as to terminate the material flow through the valve. The valve has very few moving parts and is dependable.
