Abstract: A method for making a glazed unit having three sheets. The unit includes a pair of outer glass sheets secured to outer legs of a spacer having a generally U-shaped cross section. On the base of the spacer between the outer legs is provided a layer of pliable material having a generally U-shaped cross section and having a desiccant therein. A third or intermediate glass sheet has its edge portion in the groove formed by the layer of pliable material. Movement of the third sheet toward an outer glass sheet is limited by the cooperation of the layer of the pliable material and portion of the outer legs of the spacer at the corners of the unit bent inwardly to move the layer of pliable material at the corner toward the unit during fabrication of the unit.

Abstract: Silicon compounds useful as coating reactants for the chemical vapor deposition of silicon oxide are disclosed, along with compounds useful as accelerants to increase the deposition rate of silicon oxide. The silicon-containing precursor comprises the structural formula ##STR1## wherein R.sup.1 is an alkyl, alkenyl, alkynyl or aryl radical which may be substituted, and R.sub.2 is a functional group which increases the reactivity of the silicon compound by withdrawing electron density away from the silicon atom, such as hydrogen, halogen, alkenyl, alkynyl, halogenated alkyl and perhalogenated alkyl radicals. The accelerant is a compound selected to take advantage of the partial positive charge on the silicon atom. Such accelerant compounds include Lewis acids and bases; water; ozone; trivalent compounds of nitrogen, boron and phosphorus; tetravalent compounds of sulfur and selenium; pentavalent compounds of phosphorus and a variety of metal compounds.

Abstract: A nozzle for depositing the shaped layer of the pliable material includes a platform having a shaping tip. The shaping tip has converging sides at one end and generally parallel sides at the other end. The portion of the tip at the first end has a lower elevation than the portion of the tip at the second end. Holes for moving the pliable material are provided in the platform on each side of the tip and in tips intermediate its ends. The different elevation and converging end minimizes if not eliminates tailing.

Abstract: A multi-sheet glazing unit has a pair of outer glass sheets spaced from one another and secured to a spacer frame having a generally U-shaped cross section defined by outer legs secured to a base. The recess of a sheet retaining member is mounted on peripheral edge portions of an intermediate glass sheet. The intermediate glass sheet and sheet retaining member are mounted within the outer legs of the spacer frame to position the intermediate sheet between and spaced from the outer sheets. A method of making multi-sheet units is also disclosed.

Abstract: A temperable coated article with metallic properties is prepared by coating a glass substrate with a metal-containing film such as titanium nitride, which ordinarily oxidizes at high temperature, overcoating with a protective layer of a silicon compound which forms a durable layer and prevents oxidation of the underlying metal-containing film and undercoating with a stabilizing metal-containing layer. The coated article can be tempered without losing its metallic properties to oxidation.

Abstract: A glazed unit having three sheets includes a pair of outer glass sheets secured to outer legs of a spacer having a generally U-shaped cross section. On the base of the spacer between the outer legs is provided a layer of pliable material having a generally U-shaped cross section and having a desiccant therein. A third or intermediate glass sheet has its edge portion in the groove formed by the layer of pliable material. Movement of the third sheet toward an outer glass sheet is limited by the cooperation of the layer of the pliable material and portion of the outer legs of the spacer at the corners of the unit bent inwardly to move the layer of pliable material at the corner toward the unit during fabrication of the unit. A method is also disclosed for making the triple glazed unit and for filling the compartments between the sheets with an insulating gas e.g. Argon.

Abstract: A method for coating a moving substrate provides a coating having a chemical composition which varies continuously from the interface with the substrate to the opposite surface of the coating. The method involves directing a vapor coating composition toward a substrate surface and moving portions of the vapor in opposite directions. A vapor coating mixture may include a tin-containing precursor and a silicon-containing precursor. An accelerant, e.g. a phosphorus-containing precursor, may be used with the metal-containing precursors to increase the deposition rate of the coating. The coating deposited on the substrate has regions of continuously varying weight percent of silicon oxide and tin oxide as the distance from the substrate-coating interface increases, with the surface of the coating farthest from the substrate-coating interface being predominantly tin oxide.

Abstract: A sheet restraint for a sheet shipping rack includes a first elongated tube rotatably mounted on a second elongated tube. The second tube has U-shaped member secured to each end to capture the first tube on the second tube while allowing the first member to rotate relative to the second member. A resilient elongated sheet engaging member is secured to the first member. A pair of spaced pins are mounted on the first member and engageable with the U-shaped member to limit rotation of the first member about the second member so that the rotational path of the sheet engaging member and first tube is limited. The engaging members on the second tube are slideable mounted to spaced standards at the front of a rack. In this manner the front restraint moves toward the base into engagement with the outermost sheet of a stack of sheets on the rack to maintain the sheets as an integral pack.

Abstract: An apparatus for coating a glass ribbon has an exhaust on each side of a coating unit at different distances therefrom. With this arrangement, portions of the ribbon upstream and downstream of the coating unit are exposed to coating vapors from the coating unit for different periods of time. A coating mixture includes tin containing precursors and a silicon containing precursor. The silicon containing precursor has the structural formula ##STR1## where R.sub.1 is a group which does not have an oxygen available to form a peroxide, R.sub.2 is a functional group giving the silicon containing precursor the ability to be easily converted to silicon oxide coating, R.sub.3 is a bridging group to provide for multiple silicon atoms and R.sub.4 completes the bonding on the foundation silicon atom. An accelerant e.g. a phosphorus containing precursor may be used with the metal containing precursors to increase the deposition rate of the coating.
