Abstract:
1. Apparatus for use with a section of a glass container forming machine of the I.S. type, the section comprising a plurality of blank molds each of which serves to form a parison of a glass container from moldable glass by pressing or blowing, the apparatus comprising: a plurality of sooting heads each having a burner positioned to intermittently deliver pulses of a rich, combustible supply of a fuel and an oxidant to flow toward one of the blank molds; a plurality of sparking devices, each sparking device being positioned to intermittently ignite the combustible supply of fuel and oxidant to produce a sooty flame; an ignition coil positioned within each sooting head to intermittently energize the sparking device with high voltage while avoiding interference with the proper operation of an electronic control system for the I.S. machine, and means for delivering relatively low voltage power supply to each said ignition coil.
