Abstract
Certain example embodiments of this invention relate to edge sealing techniques for vacuum insulating glass (VIG) units. More particularly, certain example embodiments relate to techniques for providing localized heating to edge seals of units, and/or unitized ovens for accomplishing the same. In certain example embodiments, a unit is pre-heated to one or more intermediate temperatures, localized heating via at least one substantially two-dimensional array of heat sources is provided proximate to the peripheral edges of the unit so as to melt fits placed thereon, and cooled. In certain non-limiting implementations, the pre-heating and/or cooling may be provided in one or more steps. An oven for accomplishing the same may include multiple zones for performing the above-noted steps, each zone optionally including one or more chambers. Accordingly, in certain example embodiments, a temperature gradient proximate to the edges of the unit is created, thereby reducing the chances of breakage and/or at least some de-tempering of the substrates.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
