Abstract: A ceiling panel support system in which framed panels are supported by slideable generally "U" shaped brackets at opposite sides of each panel, one leg of each bracket being generally hook-shaped to provide an undersupport for one edge of the panel by engagement with an overhanging portion of the frame extending above the panel and the other leg being arranged to make interlocking engagement with clips slideable in a track at the edge of the frame of an adjacent panel, the clips being moveably positioned on the frame of an adjacent panel for snap supporting engagement thereof. A panel is installed in the system by first hanging the panel vertically from two or more brackets aligned along the edge of the position in which it is to be installed whereupon it can be pivotally swung into installed position in clip-snapped engagement with brackets aligned above the opposite edge of the panel. In addition, the system allows support of panels in any of a wide range of orientations from vertical to horizontal.

Abstract: The disclosure embraces a method of spraying a binder composition of hybrid character containing both organic and inorganic materials into a fiber-forming hood or chamber onto glass fibers produced by a fiber-forming process, the disclosure embracing fibrous insulation products, such as pipe insulation and block insulation, the products embodying hybrid binder composition wherein the organic phase of the binder composition improves moldability and handleability of the fibrous product during processing and installation and which provides hardness and toughness characteristics in the products to resist or prevent handling damage and physical damage in use, the inorganic phase of the binder system providing high bond strength and improved thermal stability in the product particularly under high temperatures which may volatilize the organic binder, the inorganic phase of the binder system preventing or resisting fiber slump under high temperature conditions.

Abstract: An improved method of preparing a molten glass composition is presented. The constituents of the molten glass composition are classified into two or more melting groups according to mutual melting properties or characteristics such as volatility, corrosiveness or fusion point. Of the constituent groups one is selected and prepared as a molten base glass composition into which the remaining groups are sequentially introduced and homogenized into the base glass forming a molten glass composition of desired forming characteristics.

Abstract: A furnace contains a plurality of zones. Each zone has at least one electrode adjacent a separate electrode of an adjoining zone. The adjacent electrodes are connected to separate power supplies, specifically separate windings of a transformer. In this manner, zones can be arranged immediately adjacent each other while minimizing current paths between non-associated electrodes to substantially zero. It is therefore, unnecessary to otherwise widely space firing zones within a furnace, and the spacing within the furnace may be filled with closer adjacent firing zones.

Abstract: A bonded mat which can be stretched over projections without excessive thinning out and which permits fiber loadings of greater than 25 percent by volume. The mat includes directionally oriented strands held together by swirled strands or randomly oriented fibers, and all of which are permanently held together by a binder.

Abstract: A process for controlling the composition, viscosity, resistivity or other variables of a molten glass by sensing temperature and resistivity or viscosity and making corrections in accordance with the deviation of the sensed properties and desired properties of the glass, as for example, a desired viscosity and/or composition.

Abstract: The hydraulic head of a cold top electric furnace for melting of batch, such as glass batch, employing an electric resistance heater, is electrically controlled by sensed temperature. The temperature is measured below the batch layer or crust at the area of interface transition from the solid material to the liquid melted state. A second sensor is placed within the furnace liner below and adjacent the screen heater within the molten material. The temperature signals at either of the locations are related to the hydraulic head within the furnace. The head is controlled responsive to these temperature signals by either adding additional material or diminishing the amount of material being added to the furnace.

Abstract: Glass fibers, either in the form of individual filaments or bundles of glass fibers, which have been coated with a chemically-modified asphalt prepared by reacting a bituminous material with a chromium complex. The coated fibers can be used as reinforcement for bitumen or bitumen plus aggregate to securely tie the glass fiber surfaces to the bitumen.

Abstract: Glass fibers, either in the form of individual filaments or bundles or glass fibers, which have been coated with a chemically-modified asphalt prepared by reacting a bituminous material with an organo silicon compound in which the organic group attached to the silicon atom contains a functional group reactive with the bitumen. The coated fibers can be used as reinforcement for bitumen or bitumen plus aggregate to securely tie the glass fiber surfaces to the bitumen.

Abstract: Glass fibers, either in the form of individual filaments or bundles of glass fibers, which have been coated with a chemically-modified asphalt prepared by reacting a bituminous material with an organo metallic compound in the form of an orthoester or an organo metallic boron compound. The coated fibers can be used as reinforcement for bitumen or bitumen plus aggregate to securely tie the glass fiber surfaces to the bitumen.

Abstract: Where electrodes mounted in an electric melt furnace are inclined toward each other, the current distribution between the electrodes is the least in density in the region between the electrodes where the displacement is the widest, and increases in the region between the electrodes at the tips where the displacement is the narrowest. The maximum current density can be focused in a particular area, preferably toward the upper regions of the electric melt furnace where the batch is being melted to its liquid state. Additionally, the high density current is removed from the walls, and wear and tear on the refractory is thereby reduced. An alternate embodiment is to group a number of inclined electrodes and to excite each of the separate electrodes within the group from a separate phase of the power supply. This produces current paths between each of the inclined electrodes in the group, and is used after the furnace is cooled down and hot spots must be created to start the furnace up again.

Abstract: There is provided a process, and the product resulting therefrom, for coating a refractory block or substrate with a small particle size form of at least one platinum group metal whereby a fused layer of such metal is formed on the refractory and is directly and strongly adhered on a surface thereof. This technique can likewise be employed in such a manner that the layer is a bonding agent for purposes of bonding a separate sheet of a platinum group metal to the refractory which structure can then be employed as a glass contacting member in apparatus for handling molten glass.

Abstract: A method of making molding compounds, and particularly sheet molding compounds, wherein the reactive monomers are mixed directly with high density inorganic fillers and other ingredients of a molding compound. The monomers are converted to a resin insitu that is in or approaching the B-stage, so that the material is handleable as a solid and is moldable. Because of the amount, type, and thermal conductivity of the fillers, the resinification can be done quickly in a continuous process, by reason of the fact that the monomers are spread over a large surface area of inert fillers to provide good heat transfer, and exceedingly good process control.

Abstract: A high mast lighting system for highways, airports, parking lots and the like of the type in which light bulbs are mounted on a ring shaped platform of a diameter such that it surrounds the mast and can be raised and locked into a lighting position at the top of the mast by operation of cables extending to the base of the mast. The invention is particularly directed to a novel locking and supporting mechanism for support of the lighting ring platform at the top of the mast independent of its lift cables and in which the locking pawls supporting the ring can be disengaged from their supporting position by operating the lift cables from the base of the mast to permit lowering of the ring for maintenance such as a change of bulbs.

Abstract: Disclosed is an improvement in glass manufacturing methods of the type which involve providing water containing agglomerates of glass batch, heating the agglomerates by direct contact with furnace flue gases so as to dry them and increase their temperature, the heating being insufficient however, to cause the agglomerates to aggregate, transporting those heated agglomerates to a fossil-fueled melter and melting them in the melter. The improvement resides in the heating being done in at least two stages, the flue gases withdrawn from one stage, heat recovered therefrom and then the cooled flue gases being introduced into the other stage. The heat withdrawn from the flue gases may be employed for beneficial purposes.
