Michalik Edmund R, Misson George W: Method and apparatus having sealing means and gaseous takeoff for float glass. Industries PPG, October 26, 1971: US3615315 (11 worldwide citation)

In the manufacture of float glass, a gaseous fluid is discharged against the bottom of the glass prior to the application of tractive force to at least partially support the glass after removal from the float bath. Also, seal means are provided at the glass entrance and exit ends of the float bath t ...

Michalik Edmund R: Method of and an apparatus for controlling edge flare in thermal cutting. PPG, June 19, 1973: US3739963 (4 worldwide citation)

In a method of and apparatus for thermally cutting a piece of glass along an intended path of cut, a thermal or mechanical means modifies a stress profile at a back edge of the piece of glass along the intended path of cut to eliminate edge flare. A heat source concentrates heat on a major surface o ...

Dahlberg John R, Oravitz James L, Michalik Edmund R: Thermally directed glass cutting. PPG, Shanahan Thomas F, February 19, 1974: US3792989 (4 worldwide citation)

This invention relates to a method and apparatus for cutting glass wherein glass is thermally scored along an intended path of cut, using a non-radiant, surface heating means. A fracture is then directed along the intended path by applying a bending moment about the thermal score.
