    摘要: A glass that is ion exchangeable to a depth of at least 20 μm (microns) and has a internal region having a tension of less than or equal to 100 MPa. The glass is quenched or fast cooled from a first temperature above the anneal point of the glass to a second temperature that is below the strain point of the glass. In one embodiment, the glass is a silicate glass, such as an alkali silicate glass, an alkali aluminosilicate glass, an aluminosilicate glass, a borosilicate glass, an alkali aluminogermanate glass, an alkali germanate glass, an alkali gallogermanate glass, and combinations thereof.

    摘要: A gas jet pump (10) for producing a secondary flow of gas from a primary flow. The jet pump is disclosed as a tubular body (28) having a flow passage into which the primary flow is introduced through a plurality of jet openings (36, 38, 40) in the tubular body. Each jet opening has axial and circumferential components and is tangent with the surface defining the flow passage so as to produce a vortical flow in an axial direction within the body upon introduction of high pressure gas through the openings. The primary flow produces an amplified secondary flow through the tubular body. An annular manifold (22, 24, 26) is mounted on the tubular body to selectively feed the primary flow to the jet openings. The gas jet pump has application in sheet glass treating apparatus (50, 110), and has particular utility in apparatus used to bend sheet glass. A method of manufacturing a gas jet pump is also disclosed.

    摘要: The invention relates to a flat glass pane made of a base material, which is an alkali-containing silicate glass. The flat glass pane is characterized in that at least one surface layer is enriched with potassium and is depleted of sodium and/or lithium while an inner layer, in particular an inner layer directly adjoining the surface layer, is not enriched with potassium and is not depleted of sodium and/or lithium; and the flat glass pane has a compressive stress up to a compressive stress depth and a tensile stress starting from the compressive stress depth, wherein the tensile stress increases as the depth increases up to a tensile stress maximum arranged in the inner layer, and/or the curve of the tensile stress does not have a linear section depending on the depth, and/or the curve of the tensile stress does not have a section in which the tensile stress is constant depending on the depth.
