.~.~ Electrode position sensing or adjusting by optical operation
DEFINITION
Classification: 445/4
Electrode position sensing or adjusting by optical operation:
(under subclass 3) Method which include determining or regulating the proper location of electric terminals by means of light, ultraviolet or infrared electromagnets radiation.
(1) Note. Most of the methods in this subclass are directed to the method of positioning the filament of a lamp with respect to the base so as to make a prefocused lamp.
(2) Note. This class provides for all methods for positioning the electrodes in which the position of the electrodes is determined by the use of optical means even though another class may provide for the particular method used to assemble the electrodes. For example, processes for joining two preforms by a molding step are in Class 264, Plastic and Nonmetallic Article Shaping or Treating: Processes, by a laminating step in Class 156, Adhesive Bonding and Miscellaneous Chemical Manufacture, but such processes when optical means are used to position the
filament with respect to the base, are in this class.
