Abstract: Combustion burner panels, submerged combustion melters including one or more of the panels, and methods of making the same are disclosed. In certain embodiments, the burner panel includes a panel body having first and second major surfaces, at least one oxidant through-passage extending from the first to the second major surface, and at least one fuel through-passage extending from the first to the second major surface. Oxidant and fuel delivery conduits are positioned in the respective passages. The oxidant and fuel delivery conduits include proximal and distal ends, at least some of the distal ends positioned away from the first major surface of the panel body. In other embodiments the burner panels include a frame enclosing a porous material having through passages for fuel and oxidant. The burner panels may enable delaying combustion in a submerged combustion melter, and therefore promote burner life and melter campaign length.

Abstract: An eyeglass assembly with a bridge frame having temple tab thru-holes and lens retention receivers; a nose bridge insert; at least one lens in a single lens configuration with tabs configured to insert into the lens retention receivers of the bridge frame such that the lens tabs, or a portion thereof, protrude through temple tab thru-holes. In some embodiments, the eyeglasses are frameless, having first and second temple lugs with temple tab thru-holes and lens locking features; at least one lens in a single lens configuration having lens tabs, lens retention steps, lug locking notches; and a nose bridge insert. In some embodiments, the eyeglass assembly has a bridge frame with an integral nose bridge, two lenses, each lens having a lens tab, and a lens retention step, further having a lens hook.

Abstract: Processes and systems for producing molten glass using submerged combustion melters, including densifying an initial composition comprising vitrifiable particulate solids and interstitial gas to form a densified composition comprising the solids by removing a portion of the interstitial gas from the composition. The initial composition is passed from an initial environment having a first pressure through a second environment having a second pressure higher than the first pressure to form a composition being densified. Any fugitive particulate solids escaping from the composition being densified are captured and recombined with the composition being densified to form the densified composition. The densified composition is fed into a feed inlet of a turbulent melting zone of a melter vessel and converted into turbulent molten material using at least one submerged combustion burner in the turbulent melting zone.

Abstract: A shade for removable attachment to a headlamp assembly having a headlamp connected to a head-strap where the shade is formed from first and second flexible, translucent wall panels which may lay flat against each other when not in use. The shade includes notches formed in each wall panel to which the segments of the head-strap located on either side of the headlamp may be removably connected. The headlamp assembly and shade when connected together may be suspended from a fixed point or placed upon a flat surface thereby creating a hands-free lantern.

Abstract: Methods and systems for determining density or density gradient of molten foamed glass in a glass melter, an apparatus downstream of a glass melter, or both. A molten foamed glass is generated having molten glass and bubbles entrained therein and/or a layer of glass foam on a top surface thereof in a melter. At least a portion of the molten foamed glass is transferred into an apparatus positioned downstream of the melter, and the density or density gradient of the molten foamed glass in the melter or downstream apparatus is determined as a function of distance from a structural feature of the melter or downstream apparatus, or both, using one or more electromagnetic (EM) wave-based sensors.

Abstract: An intraocular lens (IOL) has an optic, a peripheral rim, and a reduced thickness region connecting the optic to the peripheral rim. The peripheral rim has a continuously curving outer edge that it does not include any tangents parallel to the optical axis either along its length or at the intersection of the outer edge with the anterior or posterior surfaces of the IOL.
