    摘要： PRESS BENDING GLASS SHEETS BETWEEN SHAPING MOLDS HAVING CONTROLLED TEMPERATURE DURING THE PRESS BENDING OPERATION. THE TEMPERTURE OF THE MOLDS IS CONTROLLED WITHIN A TEMPERATURE RANGE SUCH THAT WHEN THE MOLDS ENGAGE THE GLASS SURFACES SHAPING THE LATTER, THEY COOL THE GLASS SURFACES AT APPROXIMATELY THE SAME COOLING RATE AS THE AMBIENT ATMOSPHERE IN SPACES THROUGHOUT THE MOLD FACES.

    摘要： Tempering glass sheets having relatively faint iridescent patterns by exposing the opposite surfaces of hot glass to arrays of blasts of tempering medium moving in overlapping circular orbits. The blast orbits applied against one surface are offset from those applied against the opposite surface by a small proportion of the diameter of the orbits traveled by each of the blasts. Corresponding blasts of opposing arrays so offset from one another move 180* out of phase with one another in said offset orbits. The blasts are applied through nozzles arranged in a regular pattern relative to each respective glass surface to impart blasts that are relatively strong centrally and weaken progressively toward their peripheries. The adjacent orbits of movement of blasts against each glass surface are arranged relative to one another so that the rate of cooling of that surface varies from point to point as little as possible in a manner well known in the prior art. The present invention provides further improvements by arranging the blast orbits against the opposite surfaces relative to each other.

    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.

    摘要： BENDING THICK GLASS INTO HERMISPHERICAL SHAPES COMPRISING USING A MOLD OF CONCAVE ELEVATION OF MATERIAL HAVING LESS THERMAL EXPANSIVITY THAN GLASS, SAID MOLD COMPRISING A RING OF RIGID MATERIAL HAVING GREATER THERMAL EXPANSIVITY THAN GLASS AND SUFFICIENTLY SMALLER IN DIAMETER THAN THE MOLD AT GLASS LOADING TEMPERATURE TO SUPORT THE GLASS

    OVER SAID MOLD AT THE TEMPERATURE AT WHICH THE MOLD IS LOADED AND CAPABLE OF EXPANDING SUFFICIENTLY MORE RAPIDLY THAN THE MOLD TO DEPOSIT THE GLASS ONTO THE MOLD AFTER THE GLASS HAS ATTAINED A SUFFICIENTLY HIGH TEMPERATURE TO DEFORM IN RESPONSE TO EXTERNAL STRESSES.
