Abstract: A sealing device includes a waterproofing membrane, an adhesive sealant layer, and optionally a release liner, wherein the adhesive sealant layer includes at least one elastomer, at least one at 25° C. liquid polyolefin resin, and at least one inert mineral filler. An adhesive sealant composition is used to form the adhesive sealant layer. The sealant device may be used to waterproof a substrate and provide a fully-adhered roof system. The adhesive sealant composition may be used to provide a self-healing roofing membrane.

Abstract: A machine for automatically applying one or more bonding or sealing seams to the peripheral surface of a tank or vessel having a non-cylindrical cross section. More specifically the machine provides means for supporting and axially rotating a generally rectangular vessel having planar walls and connecting arcuate corners so that all of the peripheral surfaces of the vessel move under the sealing or bonding means at a constant rate of speed and at a fixed distance therefrom. The same is achieved by the use of gripper assemblies having a configuration corresponding to that of the vessel. Each gripper assembly includes a sprocket chain which corresponds to the configuration of the vessel. A sprocket wheel engages each chain to rotate the gripper assemblies and the vessel retained therebetween.

Abstract: A gravity feed and return conveyor system which may be detachably connected to a conventional metal sheet lubricator so that a single worker at a stationary station can place a sheet on the system and remove the lubricated sheet therefrom. There are three conveyor sections, the middle one acting to reverse the direction of transport of the sheet. Positive acting means are provided for effectuating the direction reversal and electrical switch means are provided for actuating the direction reversal means as well as additional safety features.
