Abstract: An induction coil heating device is provided to proximately heat an aperture mask support pin in a relatively confined space in the corner of a television panel skirt. A primary coil adapted to receive alternating current power is wound about at least one insulating support member. The primary is loosely wound in a central axial area thereof to provide an annular space, and a secondary coil with a spaced away outrigger output loop inductively coupled to the primary is wound around said support member in the space provided by the primary. The output loop is adapted to receive electrical energy for heating the support pin in response to input energy provided via said primary coil. The output loop is spaced away from the primary and sized so as to be readily insertable in the confined space of the corner of the panel skirt.

Abstract: A method of inserting and sealing an end of an aperture mask support pin into the glass of a viewing panel for a cathode ray or television picture tube by heating the pin to the softening point temperature of the glass by use of a substantially flat or pancake type high frequency induction coil and an associated iron core. The iron core may be enclosed in a leak-proof jacket for supplying a coolant to the core for cooling thereof.
