Abstract: A multiple ignition source exothermic reaction mold device. The mold device includes a crucible in a block with an open top for receiving exothermic reaction powder. A lid covering the open top has an opening therethrough. A receptacle in the lid is in communication with the opening so that the receptacle receives starting powder. The starting powder and, in turn, the exothermic weld material is ignited by alternate sources, either by a spark from an ignitor device or by an electric supply sent through an ignitor element.

The insertion sleeve includes a cylindrical portion having an external diameter less than the internal diameter of the pipe, a first end of the sleeve which may be axially inserted over the stiffener tube, and a second end of the sleeve having a shoulder to abut the pipe after axial insertion of the pipe over the first end and the cylindrical portion and having a tapered opening in angular relation to the axis of the cylindrical portion.

Abstract: A lid for an exothermic reaction mold device. The device includes an internal crucible in a block with an open top. The lid includes a lower face with an elongated opening therethrough. The lid also includes an upper face with a circular opening therethrough whereby an axis of the circular opening passes through the elongated opening. A space between the upper face and the lower face of the lid is vented through a vent between the upper and the lower face.

Abstract: A coupling for a transition between a plastic pipe and a metal piping system. In one embodiment, the transition coupling includes an adapter nut having a first end for connection with the metal piping system. A stiffener tube, affixed in the adapter nut, has an external diameter less than an internal diameter of the plastic pipe. An adapter coupling is connected to a second end of the adapter nut. A hollow gripper is positioned within the adapter coupling having an internal circumferential surface configured to grippingly engage the plastic pipe after axial insertion. At least one toroidal elastomeric seal is received over a groove in the stiffener tube to engage the plastic pipe.

Abstract: A fan assembly for an umbrella including a first integrated sub-assembly clampable about an umbrella pole. The first integrated sub-assembly has a split collar surrounding the umbrella pole, a support housing on a lower end of the collar defining a drive ring support plate, and a motor housing enclosing a motor therein on an upper end of the collar spaced from the drive ring support plate. A second integrated sub-assembly is rotatably disposable about the collar and the umbrella pole and includes a drive ring having a lower surface which is supported by the drive ring support plate of the support housing, a drive ring drive mechanism, and a plurality of fan blades coupled to the drive ring.

Abstract: A service sleeve coupled with a frost proof sillcock including a housing having an outer surface and defining an inner chamber for receiving an inner portion of the sillcock, a stem portion, and an area of water pipe that extends radially from the stem portion to the structure's water supply. The service sleeve further includes a cap having an inner surface, a first end having a diameter to receive the outer surface of the housing, and a second end having a diameter sized to slidingly receive the water pipe.

The diffuser further includes a removable vane unit. The vane unit includes multiple projections for engaging prongs on the base to secure the vane unit to the base. A ribs on the projections contact the prongs to limit vibrations. The diffuser baffles include a collar for reducing vibrations.

Abstract: An improved method and article of manufacture for introducing a locator wire into an interior portion of a pressurized, or non-pressurized, subterranean or otherwise concealed plastic pipeline. The present invention introduces a locator wire into a plastic pipeline while simultaneously minimizing the escape potential of a transported volume, such as, but not limited to, gas, water, sewerage or oil. A locator wire feeding unit initially feeds the locator wire through a locator wire alignment coupling and proceeds thereafter to project the locator wire through a valve assembly, a locator saddle, and ultimately into a plastic pipe.

Abstract: An end plug for a stab-type coupler for a plastic pipe, the coupler having a first shell with a passageway therethrough. The end plug includes a hollow, cylindrical portion having a first end and a second end. An end wall is sealably attached to the cylindrical portion first end. External threads are formed on the cylindrical portion at the first end wherein the external threads engage internal threads on an end of the first shell. At least one vent hole is provided in the cylindrical portion of the end plug between the internal threads and the second end with the vent hole allowing fluid to vent when the external threads are partially unthreaded from the internal threads on the shell.
