摘要： A glass fiber attenuation apparatus and process wherein molten glass is supplied from a molten glass body to an orifice plate at substantially atmospheric pressure to prevent molten glass flow through an orifice at which attenuation has ceased, thus permitting continuation of the attenuation process despite breakouts at individual orifices. The preferred embodiment of the method includes the steps of cooling the orifice plate undersurface to a non-wetting temperature and delivering molten glass to the orifice plate at a pressure less than the internal, surface tension-generated pressure of any bead formed on the undersurface of the orifice plate upon attenuation cessation at that orifice. The preferred embodiment of the apparatus includes a perforate pressure plate immersed in the body of molten glass and superimposed over the orifice plate to effect a pressure drop upon normal attenuation flow which is sufficient to reduce the pressure immediately above the orifice plate to substantially atmospheric pressure or, in any event, to a pressure less than the internal pressure of a bead or globule formed on attenuation cessation at an orifice. The orifice plate may be of either the planar, non-tipped type or of the tipped type, and the orifice plate may be cooled to the appropriate temperature either by gas flow cooling directed at the undersurface of the orifice plate or by fin shields.

摘要： Shingle blanks are provided. The shingle blanks include an underlay portion having a substrate coated with an asphalt coating and granules, the underlay portion having an upper edge and a lower edge. An overlay portion is adhered to the underlay portion, the overlay portion having a plurality of continuous layered segments, the layered segments having a sealant bead therebetween. A plurality of perforation lines extend in a substantially perpendicular direction from the upper edge to the lower edge of the underlay portion. The plurality of perforation lines are sufficient to facilitate separation of the shingle blank to form hip and ridge roofing shingles configured for application across a ridge or hip.

摘要： A laminated asphalt shingle including a base layer, a first decorative layer, and a second decorative layer is provided. The first decorative layer may be affixed to the base layer and to the second decorative layer by a flexible adhesive that permits the first decorative layer to move relative to both the base layer and the second decorative layer without de-bonding. The relative movement of the shingle layers permits the shingle to be folded over the ridge line of a roof without de-bonding or breaking the layers. Additionally, the relative movement of the layers when the shingle is installed over a ridge creates opposing transverse edges in which each layer is offset from the other layers as a result of the shingle bending about a different radius of curvature, thereby providing a dimensional appearance along the transverse edges.

摘要： A mixing valve for mixing steam and water comprising an inlet chamber for steam, an inlet chamber for water, and a mixing chamber for mixing the steam and the water. The mixing chamber has at least one outlet connected thereto. A valve member arranged in the steam inlet chamber is coupled to a diaphragm. The valve is responsive to pressure differentials in the water inlet chamber, and is utilized to control steam flow from the steam inlet chamber to the mixing chamber. The mixing valve includes an internal partition between the steam inlet chamber and the water inlet chamber. The internal partition includes a thermal break that minimizes the contact between the steam inlet chamber and the water inlet chamber, thus minimizing the heat transfer therebetween.

摘要： An apparatus for dispensing granules onto a moving asphalt coated sheet includes first and second granule feed chambers containing granules that are fed to a discharge slot by first and second pockets. The pockets are formed in a slidable divider positioned between the feed chambers and the discharge slot. The divider is slid between a first position and a second position by a fluid powered actuator via an actuator rod. In the first position, the first pocket is in communication with the first granule feed chamber to receive granules from the feed chamber and the second pocket is in communication with the discharge slot for discharging the granules contained in the second pocket. In the second position the first pocket is in communication with the discharge slot for discharging the granules contained in the first pocket and the second pocket is in communication with the second feed chamber to receive granules from the feed chamber.

摘要： The method for applying granules to a moving coated asphalt sheet includes selecting blend drop areas on the sheet, the remainder of the sheet comprising background areas, depositing background granule drops on portions of the background areas such that the background granule drops have generally sharp leading edges which define upstream edges of the blend drop areas and have generally fuzzy trailing edges, depositing blend drops on the blend drop areas such that the blend drops have generally sharp leading edges and generally fuzzy trailing edges which overlap the background granule drops, and then depositing background granule drops on remaining portions of the background areas. The generally sharp leading edges of the background granule drops define the trailing edges of the blend drops so that when blend drops which overlap the background granule drops are removed by inverting the sheet, blend drop areas having sharp leading and trailing edges are produced.
