Abstract:
In the fabrication of flat glass by drawing a ribbon of glass upwardly from the free surface of a molten glass bath, the uniformity of the glass currents feeding the ribbon is improved by passing an electric current through the glass in the bath between electrodes at different levels of the bath.
Abstract:
Apparatus for forming refractory masses, in situ, at selected surface locations by applying to such location a mixture of fine particles of a substance which is capable of undergoing combustion to produce heat and particles of another substance, the substances being of such composition that such heat will melt at least the surfaces of the particles of the other substance, and creating the conditions for producing such combustion.
Abstract:
A refractory furnace wall has a refractory member spaced from the inner side of a wall member so as to define an intermediate space therebetween. The wall and refractory members are interconnected by a connector member which maintains the members in spaced relationship and which may be adjusted to vary the distance between the wall and refractory members.
Abstract:
In the production 26 treatment of flat glass floating on a liquid contained in a tank formed of refractory materials and having a passageway in the refractory material extending from one region of the tank to another some of the liquid is circulated through this passageway from one region of the tank to another in order to control or regulate the distribution of heat within the tank liquid.
Abstract:
In a multiple glazing composed of two or more transparent sheets joined together by a soldered connecting strip, a spacing member is mounted between sheets adjacent the strip to support deforming compression forces between the sheets and preserve the seal provided around the peripheral region between the sheets.
Abstract:
A FURNACE TANK FOR USE IN THE PRODUCTION OR TREATMENT OF GLASS FLOATING ON A BATH OF MOLTEN MATERIAL HAS AT LEAST ONE WALL FORMED OF A REFRACTORY ELEMENT. THE ELEMENT COMPRISES A REFRACTORY BODY HAVING A REFRACTORY COATING DIFFERENT IN COMPOSITION FROM THE BODY ADHERING TO AT LEAST A PORTION OF THAT FACE WHICH IS DIRECTED TOWARD THE INTERIOR OF THE TANK. THE REFRACTORY COATING IS PREFERABLY APPLIED TO A FACE OF THE BODY IN THE FLOWABLE STATE AND SETS IN SITU.
