摘要:
The invention provides methods and equipment for storing and protecting window assemblies. In certain embodiments, there is provided a bag configured to hold a window assembly therein following the assembly's manufacture up until after the installation of the assembly. The bag is configured to be sealed and to be form-fitted to the window assembly. As such, the likelihood of the bag allowing contaminants therein or catching on something and tearing is reduced. Following the installation of the window assembly, a portion of the bag is configured for removal from the exposed surfaces of the window assembly. A portion of the bag not removed is subsequently utilized as a protective barrier for the non-exposed surfaces of the window assembly. In certain embodiments, there is provided a method for storing and protecting a window assembly using a bag of the described nature.

The present invention provides a system and method for removing contaminating moisture from a deposition chamber prior to use. Dry air, preferably hot dry air, is blown into the deposition chamber where it absorbs and removes moisture. This is done by connecting a desiccation system including a blower and a dryer to the deposition chamber. The deposition chamber is also provided with a vacuum source; this may be connected to the deposition chamber using the same line as that used for the desiccation source, or may be connected through a separate line. The dry air may re-circulate through the chamber during this flushing method, or the dry air may flow through the deposition chamber continuously. A heat exchanger may also be provided to efficiently reuse hot air used to recharge the desiccation system. The desiccation system and method are particularly suited for decontaminating a magnetron sputtering deposition chamber.

A pneumatic handling and recoating apparatus for handling workpieces, such as glass, is provided. The apparatus utilizes a holding device operatively connected to a vacuum assembly. The holding device engages workpieces by vacuum and subsequently releases them by a burst of gas. The burst of gas also facilitates the application of a coating material, such as a stain-retardant agent, to a workpiece upon release from the holding device.

The invention provides a substrate bearing a low-emissivity coating. The low-emissivity coating comprises at least one graded film region. In certain embodiments, at least one graded film region is provided between the two infrared-reflective layers of a double-type low-emissivity coating. The graded film region has a substantially continuously decreasing concentration of a first dielectric material and a substantially continuously increasing concentration of a second dielectric material. Also provided are methods of depositing such low-emissivity coatings and substrates bearing these coatings.

A sputtering apparatus is presented, especially one with a magnetron cathode and rotating target (1), and target cooling performed by a liquid coolant, preferably water, in which provision is made for the cooling to be concentrated on the area or areas of the rotating target (1) which are exposed to the heat produced by the plasma (12), and the magnets (28, 29, 30, 31) of the magnet assembly (23) form at least one cooling passage (34, 35).
摘要:
A coating for applying to a front side of a substrate, which side is facing an observer, comprises a four-layer system which is optically effective and has a high anti-reflective effect. A first layer of this system is applied onto the front side of the substrate and is, preferably, a highly-refracting TiO.sub.2 layer, the second layer is applied to the first layer and is a low-refracting Al.sub.2 O.sub.3 layer, a third layer of the system is applied to the second layer and is, preferably, a high-refracting TiO.sub.2, while the fourth layer applied to the third layer is, preferably, a low-refracting SiO.sub.2 layer. The layers can be formed by either a pyrolytic method, a plasma-supported chemical vapor deposition method, a sputtering method or a chemical vapor deposition method. Preferably, they are formed by a DC-reactive sputtering method with a magnetron.
摘要:
In a method for the production of sheets of mineral glass with high transmission in the visible spectral range and with low solar energy transmission, a coating is sputtered onto the sheet in a coating chamber by cathode sputtering with a target of an alloy of 65% tin and 35% nickel in an atmosphere with an oxygen content. The sheet and coating are then heated at 640.degree. C. and then bent in the heated state, thus producing an especially stable and electrically conductive combination.

Process for the production of contact strips on substrates, especially on plates of mineral glass. These substrates are provided with an electrically conductive surface coating which is coated on the side facing away from the substrate with at least one surface layer of a dielectric material. For the production of the contact strips, a noble metal suspension in a liquid is deposited according to the invention on the surface layer in the pattern of the contact strips. Then the substrate with the pack of layers is exposed to a heat treatment at at least 100.degree. C. until a lowered total resistance occurs through the conductive surface coating between the contact strips.

A method and apparatus is disclosed for the reactive deposition of vapors of metal compounds onto substrates by the evaporation of at least one metal by means of an electron beam in an atmosphere consisting of the reaction gas, at pressures of no more than 10.sup.-1 mbar. An electrode positively biased with respect to ground and having an acceleration voltage of at least 20 kV is disposed in the area of the vapor stream flowing to the substrate. The metal vapor is produced in an internal chamber which surrounds the evaporator and has a masked orifice opposite the substrate. The reaction gas is introduced into the internal chamber and the metal vapor and reaction gas are guided by the masked orifice toward the substrate.
