Abstract: The invention relates to a method to analyze the condition of a functional fluid comprising: (1) obtaining a sample of the used fluid; (2) placing the sample of the fluid to a test medium; (3) reacting the fluid with an indicator in the test medium; (4) analyzing visually the results of the reactor resulting in the determination of the condition of the fluid. Further an apparatus for analyzing functional fluids is disclosed in the form of a test medium consisting of an absorbent or nonabsorbent material which has been treated with a chemical indicator, marker substance or a developer or detector reagent upon which a sample of the fluid to be tested is placed. The components in the treated test medium react with components in the test fluid providing a visual indication, for example a color change, to judge the condition, the presence of a marker substance or another parameter of the fluid.

Abstract: A portable apparatus and method for demonstrating different characteristics of different fluids that includes different fluid sumps or chambers for receiving samples of the different fluids. A test shaft having different portions that are immersed in the different fluid samples in the chambers is driven by an electric drive motor at a substantially constant speed while substantially the same amount of friction or force is applied to the different portions of the test shaft at different times to increase the resistance presented to the drive motor. The additional amount of current drawn or power absorbed by the motor or strain induced in the motor drive shaft during the application of such friction or force to the different portions of the test shaft is monitored and compared to provide a comparison of the friction or power loss characteristics of the different fluid samples.
Abstract: Dispersion additive system can be applied to fibers or particles, exhibiting improved dispersion, by including in the additive system a sulfonic-acid derived compound such as 2-acrylamido-2-methylpropanesulfonic acid or a salt thereof.
