Abstract: An instrument incorporating a refractometer for measuring parameters of a fluid such as a metalworking fluid, avoids impairment of measurement accuracy due to contact of entrained air and oil with a refractometer window by temporarily interrupting the flow of the fluid through a refractometer chamber and orienting the window so that air and oil will readily separate from the window during the interruption of flow. Continued flow of metalworking flow while refractive index measurements are taken can be achieved by the use of by-pass valving arrangements.

Abstract: In an effort in solving the difficulties with cleaning cationic metal processing fluids and/or emulsions, processes for cleaning a metal processing fluid which is substantially free of fatty acids is provided herein and includes treating the metal processing fluid with dissolved air floatation. Also provided are processes for deforming metals and removing suspended foreign matter from a contaminated metal processing fluid and/or emulsions which are substantially free of fatty acids is provided and include the use of DAF technology. In one embodiment, the process is performed in the absence of a filter. In another embodiment, the process is performed in the absence of a filter which is capable of removing suspended foreign material in the contaminated metal processing fluid.
Abstract translation: 为了解决清洗阳离子金属加工流体和/或乳液的困难，本文提供了清洗基本上不含脂肪酸的金属加工流体的方法，包括用溶解空气漂浮处理金属加工流体。 还提供了用于使金属变形并从污染的金属加工流体中除去悬浮的异物的方法和/或基本上不含脂肪酸的乳液，并且包括使用DAF技术。 在一个实施方案中，该过程在不存在过滤器的情况下进行。 在另一个实施方案中，该方法是在没有能够去除污染的金属加工流体中的悬浮异物的过滤器的情况下进行的。
