A substrate transporting apparatus including a carrier that is configured to support a substrate to be processed. A plurality of holes are disposed within the carrier, each hole extending from a first surface to a second surface of the carrier, the plurality of holes including at least a first hole and a second hole. A first bearing device is disposed in the first hole, the first bearing device including a first shaft, a first head, and an internal opening extending an entire length of the first shaft and the first head. The second hole is either (i) is an open hole without a bearing device disposed therein, or (ii) has a second bearing device disposed therein, the second bearing device including a second shaft and a second head without an internal opening disposed through the second shaft.

Apparatus and methods for processing a glass sheet are disclosed. A first plurality of fluid outlets are directed at a first major surface of a glass sheet and a second plurality of fluid nozzles are directed at a second major surface of the glass sheet. The first plurality of fluid nozzles and second plurality of fluid nozzles are spaced apart at an adjustable gap, and the gap can be increased or decreased during processing the glass sheet. The apparatus and methods can be used to reduce bow in a glass sheet.

A process for thermally strengthening a glass article comprising first conveying a glass article, having a temperature above a transition point of the glass of the article, into position between two fluid bearing surfaces then moving the fluid bearing surfaces toward the glass article and cooling the glass article, with at least 20% of said cooling taking place by conduction from the glass article to the fluid bearing surfaces. Apparatuses for performing the process and products resulting are also disclosed.

An apparatus for thermally strengthening a glass sheet includes a first heat sink surface, a second heat sink surface separated from said first heat sink surface by a gap between the heat sink surfaces of distance g, and a liquid feed structure positioned to be able to feed a liquid to the gap, wherein the distance g is sufficiently small relative to a thickness t of a glass sheet to be processed such that when a sheet of thickness t is positioned within the gap of distance g, thermal transfer from a first surface of the sheet facing the first heat sink surface is more than 20%, 30%, 40% or 50% or more by conduction from the first surface of the sheet through the liquid to the first heat sink surface.

A process of strengthening a glass sheet by cooling a sheet or portion of a sheet, the sheet comprising or consisting of a glass having a glass transition temperature, given in units of C., of T, wherein the cooling is performed starting with the sheet at a temperature above T, with more than 20%, 30%, 40% or 50% or more of said cooling, at some point during said cooling, being by thermal conduction through a liquid to a heat sink surface comprising a solid.
