Abstract: A magnet wire for an electrical equipment system includes a conductor, an insulation coating at least a portion of the conductor for insulating the conductor, and at least one of a varnish and an epoxy coating at least a portion of the insulation, wherein at least one of the varnish and the epoxy include a corona suppressing material.

Abstract: A method for regulating a coupling formation includes sensing a temperature of a coupling with a non-contact sensor and sending the temperature to a control unit that regulates the temperature of the coupling formation. In addition, a system for regulating a temperature of a coupling formation includes a temperature control unit and a non-contact sensor in flow communication with the temperature control unit.

Abstract: A method for determining optimum enamel die sizes for each of a plurality of dies for fabricating magnet wire includes a series of calculations based upon an empirically determined build factor for each of the enamel coatings used in the fabrication process. The build factor is a measure of the effective diameter increase of a wire passed through a coating die when the diameter of the wire entering the die is known and a selected thickness of wet enamel coating exiting the die is known. The build factor a given enamel coating is primarily dependent upon only the solids content of the enamel coating solution, and is largely independent of the chemistry of the coating solution. A simple relationship between build factor, die size, and wire size allows consistent fabrication of magnet wire in accordance with pre-selected specifications and with virtually no scrapped wire due to oversized final wire diameters.

Abstract: Apparatus and methods for inspecting electrical connections so as to determine the presence of fault connections between magnet wires and power leads are described. The apparatus includes a processing unit, a power supply unit, and a temperature sensing unit. The processing unit includes a programmable logic controller (PLC) having a central processing unit (CPU) and a plurality of input and output slots. The power supply unit includes a power lead connector configured to couple to the motor power leads and a power relay coupled to the PLC. The temperature sensing unit includes infrared thermometers to determine the temperature at the electrical connections between the stator magnet wires forming the motor windings and the power leads. The outputs of the thermometers are coupled to the programmable logic controller (PLC).

Abstract: An aqueous solution of spent alkaline reagent containing alkali metal mercaptides obtained from the treatment of a mercaptan-containing (i.e., sour) hydrocarbon fluid with an alkali metal hydroxide, e.g., sodium hydroxide (caustic) or potassium hydroxide, is contacted with hydrogen peroxide to convert at least a substantial amount of the alkali metal mercaptides to alkali metal sulfates and carbonates thereby substantially reducing the chemical oxygen demand (COD) of the aqueous spent alkaline reagent solution.

Abstract: The presence of salt water in marine oils is determined aboard ship by using a unique combination of reagents comprising a halogenated hydrocarbon, an inorganic salt solution and an alcohol to efficiently separate the water and then using a salt-impregnated gel to determine the chloride content.

Abstract: Grease compositions containing nitrites and amines form N-nitrosamines, which are suppressed by the addition to such compositions of a combination of metal ascorbate or metal isoascorbate with alpha tocopherol.
