Abstract: A method of and apparatus for cutting relatively thick glass sheets by applying surface contact, conductive heat to the glass surface along the desired line of cut. An elongated, heated conductor rod is placed on the glass surface along the desired line of cut for transmitting heat thereto to create a thermal differential line and effect a cut therealong. Pressure means bear against the conductor rod to maintain the same in continuous contact throughout with the glass surface along the length of the desired line of cut.

Abstract: A window formed of a glass sheet having a combined electrical heating circuit and bending circuit imprinted thereon. The heating circuit comprises a series of longitudinally extending conducting lines interconnecting spaced bus bars. The bending circuit includes resistance elements in the form of electrically conducting paths extending transversely of the sheet along the lines about which the sheet is to be sharply bent and which intersect the longitudinal conducting lines of the heating circuit. Interruptions are formed along the bus bars of the heating circuit in a manner isolating the latter from the bending circuit during the formation of sharp bends in the glass sheet.

Abstract: Iridescent stains are removed from vitreous surfaces by contacting the surfaces with an aqueous solution of hydrochloric acid and sodium fluoride followed by rinsing the solution from the surfaces with water and, optionally, buffing the surfaces with an aqueous mixture of cerium oxide. The method provides benefits not only in cleaning efficiency but also in operational safety to personnel and absence of detrimental effects on surrounding building materials.

Abstract: A self-sealing quick disconnect coupling for detachably connecting a pair of fluid conveying conduits to each other while either or both conduits are subject to high internal fluid pressure. The coupling includes a pair of body members each containing a normally closed valve wherein one of the body members is provided with a valve operating mechanism which permits the valve of each member to remain in its closed position during interconnection of the members. After interconnection of the body members, the valve operating mechanism then permits and assists the valve of each body member to move to its open position whereat the valves of both members are interlocked to one of the body members to prevent closing of either or both valves during fluid flow through the coupling in its connected state, particularly when surges of high fluid pressure occur.

Abstract: A portable tie-down device detachably mounted to a recessed anchor having a plurality of crossbars. The tie-down device includes a stationary stabilizer plate having a like plurality of depending torque lugs engaging the sides of the crossbars and a body member rotatable between two positions and having a like plurality of engaging dogs alignable with the torque lugs in one position and engageable with the anchor crossbars in the other position for detachably securing the tie-down device to the anchor. A manually operable locking bolt carried by the body member and selectively engageable with a locking groove in the stabilizer mechanically locks the rotatable body member to the stabilizer on the one position, thereby locking the tie-down device to the anchor.

Abstract: This invention pertains to determination of relative elevations of various components of a float glass producing facility. The extremely flat top surface of the bath of molten tin upon which the glass ribbon is formed is utilized as a reference plane. The elevation of this surface is precisely determined, with the elevation serving as a common bench mark for measuring the relative elevations of various components along both sides of the float glass facility.

Support elements are mounted on the rack and are formed to provide anti-friction, minimal heat conducting bearing surfaces for supporting heated glazing units thereon to facilitate slight relative movement therebetween to avoid optical defects and without adverse thermal influence on the glazing units.

Abstract: An apparatus for forming relatively sharp angled bends in a flat sheet of glass including a sectionalized gravity mold structure having electrical conducting means terminating in improved contact assemblies engageable with electrically conducting frit lines or paths formed on a glass sheet. The contact assemblies are mounted on the mold structure for movement along with the glass sheet relative to the mold during bending and offer continuous positive clamping contact with the electro-frit circuitry at all times.

Abstract: A method of and apparatus for bending glass sheets to relatively sharp angles. The apparatus includes a sectionalized primary press bending member having articulated end sections for sharply bending portions of a glass sheet about lines superheated by a radiant energy heat source located above the primary press member. A reciprocal brake bar is extended into engagement with the glass sheet along the heated focal line to assist the articulated press end sections in bending the glass. Clamping devices can be used in lieu of the brake bar to secure the heat-softened glass sheet to the press member shaping surface during bending. A supplemental press member, mounted above the primary press member, is provided with shaping elements having shaping surfaces complemental to the shaping surfaces of the primary press articulated end sections for pressing the glass end portions therebetween into conformity with these shaping surfaces.

Abstract: A filtering unit for use in a fluid pressure system having an inlet port for admitting fluid flowing under pressure through a filter and a desiccant bed to a distributing chamber. During the system's compression cycle, a portion of the fluid under pressure flows from the distributing chamber through metering orifices into a purge cylinder moving a piston therein to the bottom of the purge cylinder. During the system's purging cycle, fluid flowing under pressure is admitted to the bottom of the purge cylinder moving the piston towards the metering orifices causing the pressurized fluid therein to flow at a constant rate in a reverse direction through the filter and desiccant bed into a sump which is exhausted to the atmosphere through a drain valve for renewing the filter and desiccant bed. Also , a one-way valve is provided between the inlet port and the distributing chamber to permit the fluid flowing under pressure to bypass the filter and desiccant bed in the event they become clogged.

Abstract: A method of and apparatus for controlling the temperatures of glass sheets moving bodily through a furnace by automatically varying the heat exposure time of the sheets in the furnace in accordance with temperature variations from a desired level detected in heated sheets exiting the furnace.

The press roll is provided with an elongated rigid core shaft covered by a pliable resilient body, and its ends are journalled in freely vertically movable slide mechanisms so that its weight may freely bear against the glass bracket. The core shaft may be hollow so that it can be filled with water or granular material whereby its weight can be changed to break out patterns from glass brackets of different thicknesses.
