Abstract:
A cooling ring assembly (20) and method for controlling stresses in a bent glass sheet (G) produce a strengthened bent glass sheet after the cooling is completed. The cooling ring assembly (20) includes a cooling ring (22) that supports the glass sheet edge (24), an insulator juxtaposed inboard of the cooling ring to reduce the cooling rate, and a cooler (34) for providing increased cooling to at least one localized area (36, 40, 58) of the glass sheet edge. The cooler (34) is preferably embodied by a pressurized air supply (42).
Abstract:
A glass sheet forming apparatus (20) for continuously forming a heated glass sheet includes a roller conveyor (30) defined by a plurality of interposed first and second conveyor rolls (32, 34). The first conveyor rolls (32) are mounted in a plane defined by X and Y axes for conveying the glass sheet. The second conveyor rolls (34) include independent first and second roll portions (36, 38). At least one of the roll portions (36) is movable in the plane to establish rotation of the roll portion (36) with respect to a Z direction. The second conveyor rolls (34) are mounted in a plane defined by X' axis. A first actuator (44) moves the movable roll portions (36) so that part of the movable rolls (36) are elevated above the X' axis and above the first conveyor rolls (32) whereby the roller conveyor (30) becomes non-planar and a heated glass sheet is formed as a result of the non-planar conveyor shape and upward action of the second conveyor rolls (34).
Abstract:
A glass sheet transferring device (20) is disclosed as including a movably driven frame (30), a glass sheet lifting mechanism (32) and a walking beam mechanism (28) connected to the movably driven frame (30) to provide indexed transfer of a glass sheet G during its movement from a glass sheet forming station (22).
Abstract:
A glass sheet bending apparatus (10) for bending glass sheets about a thermally stable reference is disclosed as including a mold shuttle (20) having a receptical member (22) providing a thermally stable reference point or center with respect to a glass sheet heating furnace (14) and an upper mold support including pin (62) cooperable with the first receptical member (22) so that a glass sheet can be accurately bent between molds (34, 32) mounted on the mold shuttle (20) and upper mold support (26) respectively. An upper mold support actuator (40) includes a second registering member (42) engaging a first registering member (28) of the upper mold support (26) for raising and lowering the upper mold support (26) and disengaging the upper mold support to allow relative movement between the actuator (40) and upper mold support (26) so that the same thereby realign and engage in a newly established registration during subsequent lifting of the upper mold support (26).
Abstract:
A radiant heater (12) is disclosed for heating a glass sheet heating furnace (10) and includes a base (40) having a horizontally extending heating passage (28) therein and a cover plate (42) mountable over said base (40). A horizontal flame burner (30) supplies a horizontal flame in heating passage (28) to heat radiant heater (12) and furnace (10) thereby. The burner (30) includes a combustion air and fuel inlet (54) located beneath the floor (22). A vertical intermediate portion (56) extends upwardly from the inlet (54) into the floor (22) and a horizontally extending outlet (58) extends from the vertical intermediate portion (56) into a heating passage (28) extending horizontally between upper and lower floor surfaces (24, 26). The combustion air and fuel are mixed and ignited within the horizontally extending outlet (58) to propagate a horizontally extending flame within heating passage (28) to heat furnace (10).
Abstract:
Forming apparatus (22) and a method for forming a glass sheet ribbon (G) delivered from a flat tank (44) to a topside support dev ice (74) having a downwardly facing surface to which a vacuum and pressurized gas are suppplied to support the glass sheet ribbon (G) at its upper surface (52) while a coater (78) applies a coating (80) to its lower surface (54). Another coater (86) applies a coating (88) to the upper surface (52) of the glass sheet ribbon (G). A coated glass sheet (32) cut from the glass sheet ribbon (G) has at least one surface, and as disclosed both of its surfaces (52, 54), coated so as to be protected from deterioration caused by exposure to the atmosphere.
Abstract:
Apparatus (10) for positioning a heated glass sheet (G) includes a longitudinally extending air flotation conveyor (12) for receiving and floating the heated glass sheet, a glass sheet vacuum mold (14) movably mounted above the air flotation conveyor for receiving the heated glass sheet, a glass sheet positioner (16) mounted relative to the mold for peripherally engaging and laterally and longitudinally positioning the glass sheet with respect to the mold and an array of lift jets (18) interspersed amongst the air flotation conveyor and located beneath the mold for lifting the glass sheet onto the vacuum mold through the application of lifting air on the bottom surface of the glass sheet.
Abstract:
A glass sheet tempering system (10) disclosed comprises a single station heater and quench that includes a heating source (16) for heating the glass sheet (12) and also an air supply (18) for supplying quenching air to temper the heated glass sheet (12). The heating source (16) and air supply (18) are defined by a pair of spaced and opposed plenums (20, 20') that provide heating and quenching of the glass sheet (12) generally in one location without having to transport the glass sheet (12) between separate heating and quenching stations.
Abstract:
A waste vitrification apparatus (10) having rotatable mixer impeller (16) functioning as a shaft electrode (60) and metallic vessel (14) functioning as a vessel electrode (62). A stream (12) of waste material and vitrifiable material are mixed and melted in the vessel (14) for vitrification. The waste vitrification method converts a feed stream (12) by mixing the feed stream into a glass melt (13) and melting glass batch of the feed stream (12) to form a foamy mass. The stream is dispersed by the impeller (16) to form a foam which is then densified in a settling zone (22), recovered through a spout (24) and solidified in storage containers. Means are provided to adjust the location of the mixing impeller (16) in the vessel (14) to change the depth of the settling zone (22). The impeller (16) is mounted on a drive shaft (18) having a recirculating coolant flow.
