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 pipe joint having a compound locking ring is disclosed herein. The pipe joint bell has a a segment cavity into which ring segments may be inserted through a slot on the face or outer surface of the bell end of a first pipe. The locking ring has multiple ring segments, each segment having an arcuate outer surface. The outer surface may be a compound surface of multiple arcs.

摘要： A joint having a male joint member and female joint member with enhanced ease of assembly, in which a raised stop on the male joint member is limited to displacement between a constriction on the female joint member and a locking ring segment, in which the locking ring segment and constriction are separated by an unobstructed traverse region that allows the male joint member to slide axially when under stress without separation from the female joint member, and in which a compressible spacer is installed between the male joint member and female joint member to ensure that the raised stop is installed in an intermediate position between the constriction and the locking ring segment. The compressible spacer withstands forces associated with assembly but allows the joint to compress during extreme events to prevent failure of the joint during extreme events, such as earthquakes, floods, and landslides.

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.

摘要： A joint having a male joint member and female joint member, in which a raised stop on the male joint member is limited to displacement between a constriction on the female joint member and a locking ring segment, and in which the locking ring segment and constriction are separated by an unobstructed traverse region that allows the male joint member to slide axially when under stress without separation from the female joint member. The rounded shape of the groove that accommodates the locking ring segment acts like a universal joint, allowing deflection between the male and female joint members without separation. The female joint member flares on the inside of its distal region to accommodate such deflection. Thus the male and female joint members have a degree of axial and radial flexibility.
