Abstract: A process for forming coating on an interior surface of a glass container. A glass preform is formed at blank molding station from a gob of molten glass. Thereafter, a glass container is formed at a blow molding station from the glass preform. A coating material comprising a suspension of nanoparticles in a liquid medium is introduced into an interior of the glass preform or the glass container while the glass is still hot from being formed. Heat from the glass is transferred to the liquid medium to vaporize the liquid medium and form a coating on an interior surface of the glass preform or the glass container. Thereafter, the glass container is annealed.

Abstract: The present invention provides an on-line method for stabilizing surface compressive stress of chemically-tempered glass, which comprises the steps of: placing glass to be tempered together with a stabilizer in a tempering furnace containing a molten salt bath for glass tempering; and after reacting at a temperature for a period of time, removing the glass and the stabilizer from the tempering furnace. The stabilizer is capable of chemically reacting with impurity ions in the molten salt bath for glass tempering, to remove the impurity ions in the molten salt bath. Therefore, the presence of the stabilizer allows the impurity ion content in the molten salt bath for glass tempering to be stable without gradual accumulation.

Abstract: An extruder is fitted with a connector for coupling and decoupling with a filament feed source, such as a filament tube. When connected, the extruder and filament tube are aligned to define a feed path for a filament. A tool rack includes a plurality of filament tubes secured within respective openings. The tool rack may facilitate coupling and decoupling operations between the extruder and filament sources. For example, the tool rack may define an insertion path that engages a filament tube during insertion, and that secures the filament tube against an excursion from the insertion path. The extruder may disengage the coupling by initiating a motion along the insertion path and then moving off of the insertion path to decouple the filament tube and the extruder. In this manner, filaments may be swapped through engaging and disengaging the extruder with different filament tubes on the tool rack.

Abstract: The invention relates to a method and a device for infiltrating a fiber preform of a component of fiber composite material with a matrix material. On the method side, it is proposed that an elastic coating (3) is applied onto the fiber preform (1, 23, 37), wherein the elastic coating (3) is widened to form a gap space (22) between the fiber preform (1) and the coating (3). The matrix material (21) is then fed into the gap space (22) and the elastic coating (3) is subsequently pressed against the fiber preform (1, 23, 37). On the device side, it is claimed that an elastic coating (3) is arranged on the fiber preform (1, 23, 37) and means are provided, which are in operative connection with the elastic coating (3), by which the coating (3) can be widened while forming a gap space (22) between the fiber preform (1, 23, 37) and the coating (3). A matrix material (21) can be fed into the gap space (22) and the coating (3) can be pressed against the fiber preform (1, 23, 37).

The curing module disposed in the body and under the tank. The control module is electrically connected to the rotation module, the elevating module, and the curing module. The forming platform dips into the forming material in liquid in the tank and the curing module cures the forming material between the forming platform and an inner bottom of the tank to form a solidification layer. Then the elevating module and the rotation module respectively drive the forming platform to rise and rotate relatively to the tank simultaneously.

Abstract: A nozzle deposits a filament of viscous, molten glass onto a print bed, while the print bed rotates about a vertical axis and translates in x, y, and z directions. The deposition is computer controlled, such that the resulting deposited filament forms a desired glass object that is solid after it anneals. One or more motors rotate the print bed such that the direction of deposition of the molten glass is constant relative to the nozzle, even though the print bed is translating in different directions relative to the nozzle. Keeping the direction of deposition constant relative to the nozzle tends to prevent the extruded filament of molten glass from experiencing large, changing, tensile and shear forces that would otherwise occur and that would otherwise damage the filament.
