Abstract: A method for producing fibers from molten mineral material in which the heat sink provided by air induced to flow in the direction of the bushing by the moving fibers is replaced during a period of fiber forming interruption by a secondary flow of air directed toward the bushing during the interruption.

Abstract: Apparatus and method of producing glass fibers employing a tipped or tipless annular bushing plate from which fibers are drawn as an annular array. A cooling gas, such as air, is directed into contact with the bushing plate and with either, or both, the exterior and interior of the annular array.

Abstract: The disclosure embraces a method of and apparatus for controlling or stabilizing the temperature or heat pattern at an orifice plate or feeder floor from which flow glass streams which are attenuated to fibers or filaments. More particularly the disclosure embraces a method of and apparatus for delivering streams of air or other fluid from a nozzle construction at a selected angular position into the attenuating environment and onto the feeder floor or orifice plate for cooling the glass streams and the feeder floor or orifice plate for normal attenuating operations. In event of a fiber or filament break-out or other interruption of attenuation, the angularity of the nozzle construction is changed with respect to the normal path of movement of the fibers or filaments so as to stabilize the heat pattern at the orifice plate or feeder floor and thereby facilitate restarting of normal attenuating operations.

Abstract: A method and apparatus for cooling a continuously moving strip of asphaltic material includes directing the asphaltic material into a plurality of loops having lengths and widths, spraying an evaporative liquid onto the asphaltic material from spraying means positioned upstream from various ones of the lengths, and evaporating the evaporative liquid immediately downstream from each of the spraying means by causing an array of air jets to impinge on the asphaltic material substantially normally to the lengths.

Abstract: A woven or non-woven mat comprising natural or synthetic fibers bonded together with the residue formed by removing water from an aqueous composition comprising a thermoplastic emulsion and a melamine formaldehyde resin forms an underlay for asphalt paving for road surfaces.

Abstract: The apparatus includes an air temperature and humidity control chamber, a chopper room, strand choppers in the chopper room, a first controllable pitch fan having an inlet connected to the temperature and humidity control chamber and an outlet connected to the chopper room, a forming hood beneath the choppers, an endless conveyor chain beneath the forming hood, a chopped strand collecting chamber for collecting chopped strands which happen to pass through the conveyor chain, a suction chamber disposed beneath an upper flight of the conveyor chain and partitioned into a plurality of sections each having an inlet communicating with the forming hood through the conveyor chain and being provided with nozzle-forming downstream convergent baffle plates therein and an outlet communicating with the chopped strand collecting chamber through a duct having an adjustable damper therein securable in an adjusted position, a second controllable pitch fan having an inlet connected to the chopped strand collecting chamber and

Abstract: A method and apparatus for fiberizing molten mineral material of the type in which molten mineral material is supplied to a spinner and centrifuged by the spinner into mineral fibers, is characterized by fiberizing the molten mineral material at a temperature below the liquidus temperature of the molten mineral material.

Abstract: Apparatus for rotating a spinner comprising a rotatable cap means, a quill upon which said spinner is mounted for rotation, and a threaded insert adapted to transmit a drive force from the rotatable cap means to the quill, where a stop means is mounted on the cap means and a ball mounted for radial movement with respect to the insert means is biased radially inwardly, and where outward radial movement of the ball causes engagement between the ball and the stop means to prevent relative movement between the insert means and the cap means.

Abstract: A combination comprising a recuperator, a crown vent and a furnace having a crown vent opening is supplied, the crown vent extending upwardly into the recuperator and downwardly beneath the wall of the crown vent opening.

Abstract: A process for manufacturing glass filaments in which the bushing bottom plate has tips depending therefrom and each tip has a plurality of orifices from which glass filaments are drawn. The tips flood individually on start-up or during operation, and the flood results in a single composite filament being formed from the orifices of that tip. The composite filament beads down rapidly and is subsequently separated into individual filaments by the use of a fluid spray directed against the composite filament at the tip lower face. The fluid spray is utilized to momentarily quench the composite filament and is terminated once separation occurs. Subsequent filament drawing is accomplished without the use of a cooling fluid and by the use of known heat exchange means, e.g., a flow of cooling gas.
