Abstract: A spool which is used for holding windings of optical fiber includes a first portion having a first side wall flange and defining a first locating surface and a first welding surface. The spool further includes a complimentary second portion having a second side wall flange and defining a second locating surface and a second welding surface. The first and second locating surfaces are in engagement with one another and cooperating to orient the first and second portions such that the first and second side wall flanges are in a generally parallel arrangement with each other. The spool further includes a welding material disposed between the first and second welding surfaces for securing the first and second portions together.

Abstract: A drip channel for use in the construction of exterior wall systems and an exterior wall system using the drip channel are provided. Attached to the wall of a structure is a first vertical panel having a top edge and a bottom edge. A base portion is attached to and extends from the bottom edge of the first vertical panel such that the base portion and the first vertical panel form an oblique angle with one another. The base portion has an outboard edge with a plurality of holes distributed therealong. A second vertical panel is attached to and extends upward from the outboard edge of the base portion.

Abstract: A prefabricated joint assembly molded of a single piece of plastic and used for connecting decorative channels or reveals on the exteriors of buildings. Reveals are typically used to form an aesthetically pleasing effect on the exterior surface of a building that will be covered with stucco, mortar, cement, plaster, drywall, or the like. This invention provides a relatively inexpensive joint that vastly simplifies the job of joining reveals at the construction site.

Abstract: A support for a pair of generally 90.degree. relatively angulated staple guns is provided and the support defines a pair of aligned generally 90.degree. V-shaped notches for embracingly engaging an outside dry wall corner structure. The inner portions of the V-shaped notches are relieved to receive a generally V-shaped corner bead therein and the notches are spaced apart to engage the corner bead at points spaced longitudinally therealong. The staple guns are spaced apart intermediate the V-shaped notches and include abutment surfaces from which staples may be projected, the abutment surfaces of the staple guns substantially coinciding with planes lying along and extending between corresponding sides of the notches. The staple guns include actuators shiftable between active and inactive positions and the support includes an operator shiftable along a path bisecting the included angle for operating the actuators. A V-shaped corner bead is provided including a partial cylindrical apex portion of generally 270.

Abstract: A roof air vent having rails mountable about an opening in a roof for forming a support bracket for one or more perforated panels. A pair of the rails are parallel to one another for forming tracks in which the panels are inserted.
