Hot gases may be removed and the fluid is also used to cool the regions of the apparatus contacted by the gases.
Abstract:
The invention relates to a coated glazing, a method of manufacturing said glazing and the use of a layer based on silica and/or an organo silica deposited on a glazing to achieve a coefficient of kinetic friction between an exterior surface of the layer based on silica and/or an organo silica and a contact surface wiping means that does not substantially change between a dry state and a wet state of said surfaces. Also disclosed is a glazing suitable for combination with a wiping means, the combination of said glazing with a wiping means and the use of said glazing to facilitate a reciprocating motion of a part of a wiping means and/or to facilitate a tilting and/or flipping of a part of a wiping means.

Abstract:
The invention concerns a polished coated glazing, comprising a coating on a substrate. The coating comprises a first coating layer and a silica overcoat layer, the silica overcoat forming an exposed surface, wherein the silica overcoat layer is polished such that Sa is less than 15 nm. A method of manufacturing said glazing comprises the steps of providing a substrate, depositing a low emissivity coating, depositing a silica overcoat layer to form an exposed surface of the glazing and polishing the silica overcoat layer so as to reduce roughness Sa to less than 15 nm. Another embodiment of the invention is a polished coated glazing, comprising a coating on a substrate, such that the coating forms an exposed surface of the glazing, wherein the coating comprises a polished silica layer, having an arithmetical mean surface roughness, Sa, of less than 15 nm. Further embodiments include a laminated glazing and an insulating glazing unit. To achieve a desired level of planarization of an exposed surface of a glazing requires less polishing time with a silica layer forming the exposed surface according to the invention, than a non-silica layer.

Abstract:
Methods are disclosed for planarisation of a coated glass substrate by deposition of a silazane based layer thereon. Coated substrates according to the invention exhibit improved properties in terms of reduced roughness, lower haze and higher visible light transmission and the coated surface may be exposed to the external environment, for example as surface 1 or surface 4 of a double glazing unit. The resulting smooth surface is less susceptible to marking and scratch damage, and offers enhanced surface energy (improved hydrophobicity).
