摘要： A fitting for a pipe has a cylindrical sleeve and a spigot fitted concentrically within the sleeve. The sleeve is slidable along the spigot in a proximal direction. The sleeve has a gripper ring cavity with a conical bearing surface with a diameter that is smaller at the distal end and a larger at the proximal end. One or more gripper rings fit within the cavity and slidingly engage the bearing surface. The spigot has an outer surface sized to fit within a proximal end of the pipe. The inner surface of the gripper rings and the outer surface of the spigot define an annular space with a first radial width sized to accept insertion of the proximal end of the pipe. When the sleeve is moved with respect to the spigot in the proximal direction toward a sealed position, the rings are inwardly compressed by the bearing surface to grip an outer surface of the pipe. The end of the pipe is drawn into a space between the sleeve and the spigot with radial width smaller than the first radial width.

摘要： A method of providing a continuous supply of gas to the gas utilities of a residential or commercial building while the gas meter is disconnected from the gas service lines. The method employs a bypass valve comprising a tubular fitting to be connected in line with the gas service line conducting gas from the gas meter to such building. An auxiliary source of gas may be coupled with an auxiliary port formed on the outer wall of the fitting, such that activation of the auxiliary source acts to drive a poppet through the bypass valve to seal off the gas meter from the gas service lines. Thus the gas meter may be disconnected from such gas service lines, as the auxiliary source will provide continuous gas supply to the utilities of the building.

摘要： A gas service line field completion kit for providing a service line connection through a gas meter between a gas distribution main and a gas service inlet pipe fitting spaced a predetermined distance from the main. The kit is characterized by forming an integral gas meter mounting assembly including a pressure regulator mounted thereon, forming an integral riser assembly including a shut-off valve mounted thereto and having an excess coiled length of plastic gas distribution tubing projecting therefrom, packaging the riser assembly and mounting assembly to form the kit, and storing the kit for subsequent shipment. The gas service line completion kit may be rapidly installed in the field by unpackaging the kit at the installation site, coupling the outlet end of the mounting assembly to the gas service inlet pipe, coupling the outlet end of the shut-off valve to the inlet end of the mounting assembly, and uncoiling and coupling the excess length of plastic tubing to the gas distribution main. A gas meter can be subsequently coupled to the gas meter mounting assembly to facilitate gas service.

摘要： An apparatus and method for forming a fusion welded butt joint between thermoplastic pipe sections. Thermoplastic tubular insert sleeves having end flanges are inserted into the ends of the pipe sections with the flanges located in abutting relation. A coupling collar mounting a heating device is slid along one of the pipe sections into overlying relation with the butt joint formed by the engaged flanges. The heating device is energized to fusion weld the coupling sleeve to the pipe sections and to the flanges. The insert sleeves internally support the butt joint area of the pipe sections against thermal sagging during the fusion welding, and the flanges in their molten state tend to flow and compensate for dimensional discrepancies in the pipe sections.

摘要： Selecting a dimension representing the distance between a residential gas hookup, downwardly through an intended subterranean trench to a gas main typically located along a public right of way, such as a street, and selecting a plastic pipe having a predetermined length at least equal to such dimension. Then, fabricating at a manufacturing site remote from the intended site of installation, a kit including a metallic riser having an upper end formed with a coupling screw thread and a lower end. Inserting one extremity of the plastic pipe through the riser to leave an excess length projecting from such lower end, forming a joint between the plastic pipe and such upper end, coiling such excess length into a coil and securing the assembly in a package to form the kit. A selected number of the kits may then be stored in their packaged form for subsequent shipment to the installation site to be installed and connected to make a hookup between the hookup location at respective residences and such main gas line.

摘要： An apparatus and method for attaining fusion temperature at substantially the same time throughout an interface between thermoplastic articles by the controlled application of heat. The method includes providing a sensed temperature signal corresponding with the temperature at the interface, generating a desired temperature signal (such as an analog ramp signal which increases linearly with time) corresponding with a predetermined heat application rate which causes the temperature at substantially all portions of the interface to rise substantially uniformly, providing a heat control signal corresponding with any difference between said signals, and applying heat to the interface at a rate determined by the heat control signal to achieve fusion temperature throughout the interface at the same time. The apparatus includes a heater coil to apply heat to the interface, a sensor to provide the sensed temperature signal, a generator to provide the desired temperature signal, and a differential amplifier to provide the heat control signal. Fault detection circuits stop the process if a heater fault, a temperature sensor fault, or a power supply fault is detected. Testing circuits are included to test the apparatus for proper operation before commencing fusion.

摘要： A method and apparatus for thermal fusion of thermoplastic pipes. Heat is applied to a joint interface between thermoplastic pipes and a thermoplastic coupling at a slow rate to raise the temperature of the interface to a predetermined preheat temperature, and then at a rapid rate to quickly raise the temperature to the fusion point, resulting in proper localized fusion heating at the joint interface.
