A bushing system may include a bushing that is configured to receive a molten material. The bushing may include a plate defining a first plurality of apertures through which the molten material flows. The plate may include a longitudinal axis, as well as a first side wall and a second side wall disposed on a side of the plate opposite the first side wall. The first side wall and the second side wall may extend at an upward angle from the plate. The plate may also include a plurality of ribs extending along at least a portion of the plate. The bushing system may also include a tip plate coupleable with the bushing. The tip plate may be configured to receive the molten material from the bushing and may define a second plurality of apertures through which the molten material flows to form fibers.

The present invention provides a nozzle plate and the use of the nozzle plate for producing filaments, preferably silica gel fibers.

A bushing assembly is provided including terminal ears coupled to opposed end walls of the bushing assembly. Each of the terminal ears includes an electrically conductive plate with a first terminal edge (1D) coupled to a bushing first end wall, and extending away from the first end wall to a second, free terminal edge (1A) and having a curved geometry. The curvature, 1/(2R), at any point of the curved second end of the slot is less than the reciprocal, 1/ Wo, of the smallest gap width, Wo, of both slot first open end, W.sub.A, and elongated portion, W.sub.B, where R is defined as the radius at any point of the curved second end.

There is provided a system and method for manufacturing continuous strand fiberglass of progressive density with varying skins. Glass media is melted into molten glass within a temperature controlled melter, the molten glass exits the melter through orifices of a bushing plate, which is oriented 6 degrees relative to the axis of a rotating drum. A rotating drum receives the molten glass exiting the bushing plate, and resin and water are applied. The fiberglass media is fed through rollers before it enters a curing oven.

The present invention is directed to a vertical volcanic rock melting furnace having a reduced spatial footprint relative to prior art furnaces. The melting furnace includes a top melting section, which raises the temperature of a charge above the liquidus temperature, a middle cooling section configured to reduce the temperature of the melt, and a bottom conditioning section configured to maintain the melt above a crystallization temperature before the melt is distributed to one or more bushing plates to extrude into fibers. The top melting section and the bottom conditioning sections are surrounding by induction coils for inductively raising the temperature of the melt.
