Abstract: A method of flushing a hydraulic system including a fluid circuit and an in-service fluid flowing therein includes fluidly coupling a kidney loop to the fluid circuit such that at least a portion of the in-service fluid may flow therethrough, the kidney loop including a depth media filter and a micro-glass filter arranged in a parallel flow pattern and introducing a solvent cleaner into the in-service fluid at a concentration level between approximately 2.5% and approximately 6%, the solvent cleaner including at least one hydrocarbon group V fluid. The method further includes maintaining a temperature of the in-service fluid between approximately 100 degrees Fahrenheit and approximately 155 degrees Fahrenheit and controlling the flow of the in-service fluid at a flow rate between approximately 3 gallons per minute and approximately 6.8 gallons per minute.

Abstract: Systems and methods for varnish abatement and removal from in-service fluids and components of an industrial lubricated system. The systems and methods may include adding an effective amount of a solubility enhancer to the in-service fluid, and contacting the mixture with a medium having acrylamide or styrenic functionality to remove contaminants from the mixture. Systems may include a medium circuit having a medium pump and a medium component and a solubility enhancer reservoir arranged to dispense solubility enhancer to the reservoir. Methods may include pre-conditioning the in-service fluid before adding solubility enhancer.

Abstract: A light weight, portable spectroradiometer device has an optical system that directs incoming wavelengths of light to impinge upon a three-dimensional sensor comprised of a linear variable filter in direct contact with a photodiode array. The linear variable filter can be a specific band pass filter coating that has been geometrically wedged in one direction. The incoming wavelengths of light are transmitted through the three-dimensional sensor and differentiated into the pixels to be further processed into digital signals. A standard light source, either external or internal to the device, and emitting specified intensities over wavelengths may also be used to calibrate the spectroradiometer device, and samples of light with unknown intensities may be compared to the standard light source. The compact geometry of the optical system and sensor allows the device to be a compact, light weight three-dimensional spectroradiometer containing no moving parts and having a rapid measurement time.

Abstract: A method of inserting into a non-polar fluid flow a quantity of a solid medium having porosity, preferably a crosslinked polystyrene resin, which absorbs or adsorbs oil oxidation by-products or other lubricant degradation products or varnish precursors dramatically to extend the life and performance of the lubricating oil.

Abstract: Impedance spectroscopy is used to determine values associated with properties of a substance such as a fluid. In some embodiments, the present invention is applied to engine lubricants. A spectral matrix is constructed that comprises data taken from spectral plots. Also constructed is a result matrix comprising known quantities of a plurality of fluid constituents. A known analytic technique is performed on the spectral matrix to identify at least one principal component having significant influence on the spectral matrix. A reduced spectral matrix, wherein each column in the reduced spectral matrix is associated with a principal component having significant influence on the spectral matrix, is next created. A statistical technique uses the reduced spectral matrix and the result matrix to create at least one prediction equation. The prediction equation is used to predict at least one property in a second substance in situ.
