Abstract: A power generation systems with solid oxide fuel cell (SOFC) and heat recovery unit (HRU) and method are provided. In accordance with one embodiment of the disclosure, a power generation system includes a partial oxidation (POX) reactor, an array of one or more fuel cell stacks and an HRU. The POX reactor is operable to generate a hydrogen rich gas from a fuel. The array of one or more fuel cell stacks includes at least one SOFC and is coupled to the POX reactor. The fuel cell stacks are operable to generate electrical power and heat from an electro-chemical reaction of the hydrogen rich gas and oxygen from an oxygen source. The HRU is coupled to the array of fuel cell stacks and operable to generate electrical power from the heat.

Abstract: The present invention relates to a plumb-bob and magnet combination for attachment to a beam. The plumb-bob and magnet combination for attachment to a beam includes a magnet having a top flat surface that is connected to the base, the magnet having two opposing sides that contain recesses, a hollow casing for encompassing a string of the plumb-bob and having a top surface slidable along the magnet, the hollow casing including lips on the top surface for sliding engagement with the recesses on the sides of the magnet, a lock on one of the lips of the casing and being cam operated by a lever that moves in the direction of an arc on the top surface of the casing for locking and unlocking the casing to the magnet, and a cantilever extending from the casing and having a free end with an aex from which the string hangs with a weight at the free end, the string being wound in the casing.
