摘要:
A method for making a vacuum insulated glass window assembly is provided in which an exposed end of a pump-out tube of a vacuum insulated glass window assembly is sealed using a laser that is applied to the end of the pump out tube in controlled sequential manner as opposed to a short duration, high-powered application of a laser. In particular, a method is disclosed in which a multiphase sequential variable power application of laser energy to an exposed end of a pump-out tube for controlled exposure times and decreasing laser trace diameters produces a more controlled melting of the tube glass to reduce or eliminate undesirable outgassing that may occur during a high-power short duration exposure of laser energy to the end of the pump-out tube to seal the tube.

A vacuum insulated glass (VIG) window assembly and method for making same is provided in which a variation in the final edge seal height is preferably 0.20 mm or less, more preferably about 0.15 mm or less. Controlling final edge seal height variations substantially reduces breakage of the glass substrates of the VIG window assembly during vacuum pump-down of the cavity between the glass substrates. Edge seal height variation may be controlled, for example, by controlling initial dispensing of green frit material, controlling temperature variations during firing, and/or controlling cycle times during firing.

A composition for optimally removing or etching metallic alloys from chemically compatible substrates with minimal damage to the substrate. The preferred composition is Ammonium Fluoride, Hydrofluoric Acid, Nitric Acid, Phosphoric Acid and Water in a specified range of quantities used to selectively remove an Aluminum and Silicon Alloy and Titanium film from a chemically compatible substrate. The composition is placed in contact with Stainless Steel, Silicon, or other organic or metallic substrates to remove, etch, or pattern homogenous or layered Aluminum, Silicon, Titanium and Copper Alloys from the substrate with minimal etching to the underlying substrate.

Tapered openings are formed in silicon oxide layers on a substrate by first saturating the silicon oxide layers with water, such as by immersing the substrates and the silicon oxide layers in water. The silicon oxide layers are then heated to dehydrate them to a desired water content at which a desired adhesion of a resist layer to the silicon oxide layer is achieved. A photoresist layer is then coated on the silicon oxide layers and photolithographically defined to provide them with openings therethrough over the area of the silicon oxide layers where the tapered openings are to be provided. The exposed area of the silicon oxide layers are then etched with an etchant for silicon oxide, such as buffered hydrofluoric acid, containing a component for lifting the edge of the resist from the silicon oxide, such as an acid, to etch tapered openings through the silicon oxide layers. Saturating the silicon oxide layers with water and then dehydrating them ensures that the openings have walls of uniform taper etched therethrough.

A motor-driven marine propeller is disclosed for propelling a marine vessel. The propeller includes a hub member driven by the motor and a can member disposed coaxially relative to the hub member the can member having a fore and an aft end. The hub member and the can member define therebetween an annular port for the passage therethrough of a portion of the exhaust generated by the motor. Supports extend between the hub member and the can member for supporting the can member coaxially relative to the hub member and a plurality of blades are secured to and extend from the can member with each of the blades being equidistantly spaced relative to each other. Each of the blades defines a leading and a trailing surface such that the propeller rotates in a direction from the trailing towards the leading surface in normal forward motion. A plurality of notches are defined by the fore end of the can member and each of the notches is disposed adjacent to a trailing surface of an adjacent blade such that the notches cut through filamentary material entangled around the propeller and reduce the generation of eddies during rotation of the propeller.
摘要:
A method for making a vacuum insulated glass window assembly is provided in which an amount of wet frit material is applied to a lower portion of a pump-out tube prior to insertion of the tube into a hole formed in a glass substrate of the VIG window assembly. The tube is then inserted into the hole, frit paste end first. An amount of frit may overflow the hole and form a bump/shoulder of frit material proximate the area of the hole on an outer surface of the glass substrate. Applying the fit to the tube prior to insertion and at a lower portion thereof reduces the amount of and/or avoids residual frit being deposited in an area of the tube that might significantly interfere with subsequent sealing processes, such as, for example, laser sealing of the pump-out tube.

Certain example embodiments relate to seals for glass articles. Certain example embodiments relate to a composition used for sealing an insulted glass unit. In certain example embodiments the composition includes vanadium oxide, barium oxide, zinc oxide, and at least one additional additive. For instance, another additive that is a different metal oxide or different metal chloride may be provided. In certain example embodiments, a composition may be combined with a binder solution that substantially or completely burns out by the time the composition is melted. In certain example embodiments, a CTE filler is included with a frit material. In certain example embodiments, a vacuum insulated glass unit includes first and second glass substrates that are sealed together with a seal that includes the above-described composition.
摘要:
A method and apparatus for cleaning a cavity of a vacuum insulated glass window assembly is provided in which a cleaning gas mixture of or including ozone is introduced into the cavity of the vacuum insulated glass assembly and allowed to react with residual materials, such as, for example, hydrocarbons and/or polymers. Reacted hydrocarbons and/or polymers are then removed from the vacuum cavity along with any residual cleaning gas mixture. The cleaning method is preferably performed at substantially ambient temperatures or at least temperatures below about 250° C. The ozone cleaning cycle may be repeated multiple times and followed by additional purges with other gases, such as for example nitrogen. Additional energy may be provided by heating, RF plasma; corona discharge, UV lamp, and/or the like.
