Abstract: A shingle coating asphalt composition is provided that is produced from a paving grade asphalt. The asphalt composition comprises a paving-grade asphalt that has been modified with one or more polymer additives; and a secondary additive comprising one or more of a viscosity reducing agent, a wax, a salt of a fatty acid ester, and an amide of a fatty acid. The shingle coating asphalt coating composition is used to make a shingle. The shingle includes a substrate, the asphalt, and roofing granules.

Abstract: A finger follower for use in an internal combustion engine valvetrain having a valve, a lash adjuster, and a camshaft having a lobe. The finger follower includes a shaft, a bearing rotatably supported by the shaft for engaging the lobe. A body is provided with a pad for engaging the valve, a socket spaced from the pad for engaging the lash adjuster, and walls disposed between the pad and the socket. A slot is formed in each wall for supporting the shaft, and each has a respective pair of eccentric arc-shaped bearing surfaces arranged to allow the shaft to rotate within the slots and to move along the slots to facilitate alignment of the bearing with respect to engagement with the lobe independent of alignment of the pad with respect to engagement with the valve and of alignment of the socket with respect to engagement with the lash adjuster.

Abstract: A cam follower rocker arm is provided comprising a body with a U-shape cross section with an intermediate opening at the top of the inverted U-shape and having an outside width less then the inside width of the opening, creating a ledge perpendicular to the body side walls. A roller having a peripheral step on both sides to allow the smaller width at the roller periphery to extend into the body opening with the larger width of the roller maintaining a close running clearance of the roller sides to the inside walls of the body when the roller is assembled in the body.
