    摘要： TEMPERING A HEATED GLASS SHEET BY IMPARTING A PATTERN OF MOVING BLASTS OF TEMPERING MEDIUM, SUCH AS AIR, AGAINST THE MAJOR SURFACES OF THE HOT GLASS SHEET FROM A PAIR OF SETS OF SPACED PARALLEL PIPES EACH HAVING SUBSTANTIALLY EQUI-DISTANT APERTURES. ALL OF THE APERTURES ARE ARRANGED IN ROWS EXTENDING AT AN OBLIQUE ANGLE TO THE AXIS OF LINEAR RECIPROCATION OF RELATIVE MOVEMENT BETWEEN THE GLASS AND THE APERTURES AND IN ROWS APPROXIMATELY NORMAL TO SAID AXIS. THE PIPES ARE RECIPROCATED IN UNISON ALONG AN AXIS OF RECIPROCATION TO PROVIDE AN AMPLITUDE OF RECIPROCATION SO RELATED TO THE APERTURE SPACING AND SAID ORIENTATION OF THE OBLIQUE LINES OF APERTURES THAT EACH APERTURE OCCUPYING A FIRST POSITION AT ONE END OF ITS RECIPROCATION PATH IS DISPLACED TO A SECOND POSITION BETWEEN CORRESPONDING FIRST POSITIONS OCCUPIED BY OTHER APERTURES FROM THE OBLIQUE LINES OF APERTURES AND FROM THE TRANSVERSE ROWS OF APERTURES. THIS ARRANGEMENT PROVIDES A SUBSTANTIALLY EQUAL APPLICATION OF TEMPERING MEDIUM TO EACH INCREMENT OF GLASS SHEET SURFACE.
