Abstract: A system and method are described herein that control the environment (e.g., oxygen, hydrogen, humidity, temperature, gas flow rate, pressure) around one or more vessels in a glass manufacturing system. In the preferred embodiment, the system includes a closed-loop control system and a capsule that are used to control the level of hydrogen around the exterior (non glass contact surface) of the vessel(s) so as to suppress the formation of gaseous inclusions and surface blisters in glass sheets. In addition, the closed-loop control system and capsule can be used to help cool molten glass while the molten glass travels from one vessel to another vessel in the glass manufacturing system. Moreover, the closed-loop control system and capsule can be used to maintain an atmosphere with minimal oxygen around the vessel(s) so as to reduce the oxidation of precious metals on the vessel(s).

Abstract: The level of precious-metal inclusions in glass products, e.g., glass substrates for liquid crystal displays, is reduced by stirring molten glass in a stir chamber (11) under conditions such that the magnitude of the shear stress ? on the chamber's wall (19) and on the surfaces of the stirrer (13) is reduced while at the same time, the Q•E product for the system is kept high, where Q is the flow of glass through the stirring system and E is the system's stirring effectiveness.

Abstract: A glass melting furnace is disclosed having a refractory melting vessel provided with a protective liner formed of an oxidizable refractory metal such as molybdenum, wherein the liner projects upwardly within a molten bath contained within the vessel and through its fusion line into a batch blanket retained thereabove which is low in carbonates. The upper end of the liner is provided with a seal to prevent the flow of batch material between the liner and the refractory vessel and thereby prevent contamination of material behind the liner and reduce corrosion of the refractory vessel.

Abstract: An oil dip stick wiper has two hinged opposing wiping blocks with pads having opposing wiping faces biased apart by a leaf spring. The wiper has projecting grips on the outside of the wiping blocks. A walled storage container open at one end has slots in its walls to receive the closed wiper and allow access to the grips for insertion and removal of the wiper.

Abstract: A molded ice scraper one piece body has independently flexible finger portions terminating in aligned scraping edges that are joined by webs a few thousandths of an inch thick. A continuous, but breakable, blade is thereby formed that will clean a streak-free swath on a windshield or similar surface. The slots separating the fingers are curved where they meet the scraper intermediate section, to eliminate stress concentration. The fingers have forward facing ice deflecting surfaces at an obtuse angle to the surface to be cleaned, extending from the scraper edge, and front facing ice chipping surfaces extending vertically upwardly from an intersection with the ice deflecting surfaces that is spaced back from the scraper edge.

Abstract: An ice scraper comprising a one-piece body defining a handle section, a downwardly curved intermediate section, and a blade region comprising a plurality of downwardly curved, independently flexible, resilient scraping fingers. In use, the scraping fingers bow or flex when scraping force is applied to ice to be removed, induce the formation of fractures in the ice, and thereafter resiliently return to their unflexed position, imparting force to fractured ice tending to throw it away from the surface to be scraped.The separable, independently flexible fingers enable the ice scraper to effectively conform to curved surfaces and avoid the possible incomplete cleaning action of said blade structures.

Abstract: Level indicating devices wherein at least a side portion of a bubble cavity is defined by a reflecting surface having at least a linear cross section lying generally in a plane aligned with or paralleling a light source and a bubble image observer (i.e. person or sensor).

Abstract: Filter case rotatably carries two filter retainers each with a linearly polarized filter, each at the same angular position. A perforated belt engages around the sprocket teeth on the filter retainers so that the two filters are rotated together. Filter case is removably attached to the camera body.
