摘要： A brake drum of the heavy-duty type especially for use on trucks and busses where the exterior surface of the cast iron drum has a plurality of helical fins thereon arranged at an angle of 45* to the axis of the drum. The fins are either formed of the same material as and integral with the cast iron brake drum, or the fins may be formed on a shell of a higher heat conductivity than cast iron, such as aluminum, that is cast onto and interlocked with a cast iron sleeve forming the inner friction surface. A third embodiment of drum structure utilizes a plurality of aluminum rings pressed onto the cast iron drum and provided with arcuate generally circumferential fins which terminate at each end in an angularly disposed tip or edge to enhance lateral airflow.

摘要： A method of reconstructing worn cylinder heads, where only the inner face of the cylinder head forming a portion of a cylinder for a piston exhibits wear, including the steps of severing the worn portion from the remainder of the cylinder head, providing a new casting to be substituted for the worn portion, preparing the abutting surfaces of the unworn portion of the cylinder head and the new casting, applying a suitable flux to the surfaces, inserting a brazing alloy gasket of a configuration of the cross section of the cylinder head at the line of severance, aligning the parts together, heating the parts and brazing alloy to approximately 1,325* F. for approximately 2 hours, and slowly cooling the bonded parts.
