Abstract: A power generation system includes one or more micro-turbine electric generators (“MTEGs”). The MTEGs include a housing having an inlet for receiving pressurized gas and an outlet for releasing expanded gas. The MTEGs also include a rotor, a user-replaceable nozzle for directing pressurized gas over blades of the rotor, and a stator for generating alternating current (“AC”) responsive to rotation of the rotor. The power generation system also includes a programmable logic controller (“PLC”) coupled to the MTEGs that operates flow control valves (“FCVs”) coupled to the MTEGs to modulate the flow of gas to the MTEGs to generate output power suitable to support an electrical load. The system also includes power conversion circuitry configured to convert AC generated by the MTEGs to direct current (“DC”) and to provide the DC to an electrical load. The system also includes a skid for mounting multiple and MTEGs and FCVs.

Abstract: A lightning protection system for liquid storage tanks having floating roofs wherein lightning energy is not directed into the shell of the storage tank. The lightning protection system includes at least one low-resistance low-impedance bypass conductor cable configured for lightning related frequencies and for routing lightning energy and for bounding charges away from the shell of the storage tank.

Abstract: An early streamer emission terminal is disclosed. According to some embodiments, the early streamer emission terminal can create an upward propagating streamer earlier than conventional lightning protection systems and/or devices. In particular, the early streamer emission terminal can collect ground charges during an initial phase of thunderstorm development. When a thunderstorm begins to generate downward step leaders, the ambient electric field around a grounded lightning protection system can induce a current into the grounded lightning protection system. The induced current can include a flow of negative charge toward the ground, while a positive charge can be released to form an upward streamer. The construction of the early streamer emission terminal can trigger the flow of positive upward charge microseconds earlier than traditional lightning rods or other similar devices.

Abstract: A vibration isolator for use between a support structure and a roller thrust bearing including a first race, a second race, a bearing cage and at least one roller element. The vibration isolator includes a radially extending portion with a mating surface, a bearing surface, an inner peripheral edge and an outer peripheral edge, the radially extending portion being substantially disk-shaped. An annular flange extends axially from one of the inner peripheral edge and the outer peripheral edge of the radially extending portion, and at least one groove is defined by the mating surface of the radially extending portion. The bearing surface is configured to abut one of the first race and the second race and the mating surface is configured to abut the support structure such that a void is defined between the at least one groove and the support structure.

Abstract: A weighting agent for use in a wellbore fluid composition is provided. The weighting agent includes a ferrosilicon material, wherein iron is present in the ferrosilicon material in an amount equal to or greater than about 50% by weight of the ferrosilicon material. A composition including a wellbore fluid and a weighting agent, as well as methods for using and making a weighting agent, are also provided.
