Abstract: Methods of producing luminescence by application of a time-varying electrical signal to an electroluminescent device are disclosed whereby the entire system remains at open circuit. At least one article, substance or material, the “object”, is employed to alter the electrical signal to the area of the electroluminescent device to a level sufficient to change light emission. Methods are disclosed to relate the light intensity thus produced to a property of the object thereby allowing a measurement of the property. The method may optionally use one or more additional circuit components.

Abstract: A system and method for monitoring and altering the conditions of a sewage system comprising a wet well connected to a sewer. The wet well is also configured to provide sewage to a secondary system, where the sewage is fed into an oxygen contact chamber. That chamber is fed oxygen which is dissolved into the sewage such that the sewage in the contact chamber has elevated oxygen content. That oxygenated sewage is then fed into the sewage system in order to raise oxygen levels and control anaerobic activity. Sensors and valves of the system are controlled by a central controller which provides for improved functionality, energy savings, and automated function.

Abstract: A method and apparatus for separating air to produce a gaseous oxygen product in which the air is separated in an air separation plant to conduct a cryogenic rectification process that utilizes higher and lower pressure compressed air streams. The higher and lower pressure compressed air streams are generated in two multistage compressors linked together so that the lower pressure compressed air stream is produced from intermediate stages and the higher pressure compressed air stream is produced from higher pressure compression stages. During turn-down operational conditions, one of the two multistage compressors can be shut down to decrease the flow of air and therefore, the production of the oxygen product.

Abstract: Embodiments described include methods for maintaining the pH and alkalinity during industrial fermentation processes are described that foster optimal microorganism activities throughout the duration of the fermentation process. Magnesium based buffering agents having sufficient buffering capacity and applied at sufficient concentration levels required to neutralize the acidic content of fermentation fluids during the fermentation process cycle are detailed. These magnesium based buffering agents control fermenter processes without causing extreme pH swings to maximize the production of desired fermentation products.

Abstract: Methods and compositions utilizing aluminum, magnesium, and calcium-based additives for the treatment and neutralization of wastewater are described for removing contaminants from wastewater, including reducing phosphorous-containing compounds, total suspended solids (TSS), biological oxygen demand (BOD), fats, oils, and greases (FOG), and total Kjedahl nitrogen (TKN) are described.

Abstract: A system for adjusting the height of a boom on a pipe handling apparatus. A cavity is formed in the base between proximal and distal ends. The boom is nestable in said cavity and has a distal end guided along the base. A pivoting member is pivotally coupled to said boom for raising a proximal end for positioned adjacent a work floor for handling of pipe therebetween. A plurality of ports are arranged along the boom at a pre-determined spacing. A plurality of ports are is similarly arranged along the same predetermined spacing along the pivoting member. The spacing of the boom and arm ports is such that a hinge pin can engage any one of corresponding pairs of boom and arm port when the boom is lowered to nestle inside the cavity as each boom port corresponds with an arm port.
