Etching glass

A method of etching a glass sheet using a curtain coater includes supporting the sheet at its periphery and in a generally horizontal position such that it may sag under its own weight. Sagging causes the uppermost surface of the glass sheet to assume a generally concave form. Etchant solution applied to the uppermost surface flows over the glass to form a nonuniform layer on the uppermost surface. The layer has a minimum thickness at the periphery of the glass sheet. Etchant solution is applied to the glass using a curtain coater designed to handle a corrosive etchant solution. The sheet of glass is supported on a frame including a seal to prevent etchant solution from contacting a second surface of the glass.

... 144,737. Ueda, T. Nov. 30, 1917, [Convention date]. Frosted glass.-Relates to a process for producing a mat surface on glass. According to the invention, the glass surface is coated with a composition containing a substance, which, when heated, reacts on the glass to form an acid-decomposable product. The composition also contains a relatively inert substance and a binding- agent. The coated surface is heated to the required extent and, after cooling, the acid-decomposable matter is removed by an acid other than hydrofluoric. As an example, a composition consisting of basic lead silicate, pulverized porcelain and a binder such as gum, is described.

Porous Glass Membrane

A porous glass membrane for reverse osmosis desalination of salt water is made by heating a membrane of a sodium-boron-alumino silicate glass so that it separates into two inter-connecting phases, removing one phase to make the membrane porous, and then coating the pores with a metal oxide to modify the pore size distribution and strengthen the membrane to enable it to withstand the high pressure applied in the reverse osmosis process. The porous glass is first treated with a volatile metal chloride such as titanium chloride, and the resulting surface layer is hydrolyzed to produce the metal oxide coating. A further reduction in pore size with an accompanying increase in strength can be made by partially sintering the treated membrane.

METHOD AND DEVICE FOR SEPARATING A SUBSTRATE

A method and device for separating a substrate with a laser beam.
