Abstract: A heater and a method for heating a circulating liquid in a gas-to-liquid heat exchanger and an indirect heat exchanger to produce a hot liquid stream for use for heat exchange in a selected process to supply heat to the process. One particularly useful application of the present invention is the revaporization of liquefied natural gas (LNG).

Abstract: An aluminum plate heat exchanger which may include a first core and a second core defining a piping space therebetween. The exchanger also may include at least one inlet manifold and at least one outlet manifold, each manifold in fluid communication with the first core and the second core. The exchanger may also include inlet piping in fluid communication with the inlet manifold; and, outlet piping in fluid communication with the outlet manifold. In certain embodiments, at least a portion of the inlet piping or at least a portion of the outlet piping is positioned in the piping space.

Abstract: A portable circuit interrupting apparatus for use on a circuit isolating device and associated methods of formation and use are provided. The portable circuit interrupting apparatus includes a main housing body and a sleeve coaxially mounted therein. The sleeve is slidable between an extended and retracted position. A shunt circuit segment is connected between ring and hook engaging terminals which engage and form an electrical connection between ring-like and hook-like conducting parts of the circuit isolating device. A shunt circuit segment interrupts the electrical connection in response to movement of the sleeve from the retracted position to the extended position. At least portions of a reset plunger extend inwardly through an opening in a medial portion of the sleeve when in the extended position. An operation counter is connected to and responds to the inward extension of the reset plunger to count a number of circuit interrupting operations.

Abstract: A portable utility power line pole and associated methods of assembly and use are provided. The portable utility power line pole includes a pole body adapted to be held in the hand of a user. The portable utility power line pole also can include a tool connector adapted to mount a utility power line tool for use in association with electrical power distribution lines. An alignment indicator in the form of a visible line is positioned on an outer surface of the pole body in alignment with the tool connector to provide the user visualization of a user selected orientation of the utility power line tool when mounted on the tool connector and when the user manipulates the portable utility power line pole at a proximal end of the pole body to select the orientation of the utility power line tool.

Abstract: A utility wildlife protection system is provided including a utility wildlife protector and an installation tool. The utility wildlife protector preferably includes a pair of pivotally connected wildlife guards and a pivot connecting member that can be engaged by an installation tool so that installation can be achieved by a single installer from a great distance away from high voltage equipment to reduce the risk of contacting high voltage equipment.

Abstract: A load-breaking and load-returning apparatus and method of breaking and returning a load are provided for quickly breaking and returning a load to portions of a power line. The apparatus preferably includes at least one power line jumper cable including first and second cable ends and a first connector connected to the first cable end of the at least one power line jumper cable for connecting the at least one power line jumper cable to a portion of a power line. A load-breaking and load-returning device is preferably connected to the second cable end of the at least one power line jumper cable for quickly breaking and returning a load to portions of a power line responsive to a user thereof. The load-breaking and load-returning device preferably includes a second connector for connecting the load-breaking and load-returning device to a portion of a power line.

Abstract: A method and apparatus for removing hydrogen sulfide from a molten sulfur stream containing hydrogen sulfide and hydrogen polysulfides by mixing the molten sulfur stream with a degassed molten sulfur stream in an eductor to form a mixture, contacting the mixture with a finely dispersed gaseous oxidant stream, separating hydrogen sulfide from the mixture and recovering molten sulfur having a reduced hydrogen sulfide content.
