摘要： A part of a gasket that conducts electricity across the otherwise nonconducting gasket. Versions of the insert provide an electrical connection when installed even if the parts sealed by the gasket deflect, and do not deform under compression due to their resilient nature. The gaskets can be used in pipe joints, among other uses, resulting in a pipe joint that conducts electricity between the pipe spigot and the socket of a pipe or fixture even if a deflection event occurs.

摘要： A method and apparatus for centrifugal casting, in which transfer functions are developed relating the fluidity of molten metal, for example iron of varying composition, to casting machine movement for a particular mold in order to cast objects, for example pipe, having desired and uniform characteristics, including wall thickness. Fluidity is calculated for each pour of molten metal based on the measured pour temperature and measured liquidus arrest temperature. A drive system controlled by a programmable logic controller moves the casting machine in accordance with the output of the transfer functions based on the calculated fluidity.
