Abstract: A roofing underlayment includes a flexible sheet made of felt at least partially impregnated with a coating material. The sheet is provided with at least one ridge extending in a substantially longitudinal direction. The ridge projects upwardly from the sheet and is flexible such that the ridge is collapsible when a downward force is applied thereto. The ridge is defined by a portion of the sheet. A method for making the roof underlayment is also disclosed.

Abstract: A building product comprising a composite board having a cellular, non-elastic core, top and bottom board surfaces, and a facer comprising a non-cellulosic fiber mat substrate; and a water-based overlaying material applied to the composite board. The building product may also comprise an undersiding; a composite board having a cellular, non-elastic core and top and bottom board surfaces and facer comprising a non-cellulosic fiber mat substrate fixed to the undersiding; a reinforcing layer fixed to the board; and a water-based overlaying material applied to the reinforcing layer.

Abstract: A compact and short tampon applicator is formed of an outer barrel which surrounds a tampon-holding inner tubular plunger which is slidable within the outer barrel. A portion of the wall of the plunger defines a pair of hinged panels which snap into the interior of the plunger in response to an inwardly directed radial force. This inward force is supplied by a tab on the barrel, once the plunger has been retracted sufficiently out of the barrel to register the hinged panels with the tab. The applicator is readied for use by retracting the plunger rearwardly behind the tampon, sufficiently to cause the hinged panels to engage the tab on the inner surface of the barrel to snap into the plunger. After insertion of the barrel into the catamenial canal, the plunger is pressed inward, back into the barrel, to enable its inwardly snapped panels to engage the rear of the tampon and to eject the tampon through the front of the barrel.
