Patent number: 11573109Abstract: 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.Type: GrantFiled: November 19, 2019Date of Patent: February 7, 2023Assignee: HOUGHTON TECHNICAL CORP.Inventors: Alan E. Cross, John M. Burke

Patent number: 10308891Abstract: A novel hydraulic fluid composition for application to drilling equipment is described herein. These hydraulic fluid compositions permit effective monitoring or controlling well-head pressure of a well during drilling on land or offshore. The hydraulic fluid compositions prevent uncontrolled flow of gas, oil, or another well fluid out of an underground formation during a drilling or extraction process when applied to the drilling equipment. Accordingly, provided is a hydraulic fluid concentrate which contains a water-soluble phosphate ester and a sulfide compound containing at least one S—S linkage, at least 10 carbon atoms and at least one terminal carboxylate group, wherein the S—S linkage bridges two alkyl groups. Additional components can be added to the concentrate and include one or more alkaline compound, one or more dicarboxylic acid or salt thereof, a water-soluble corrosion inhibitor, a water-soluble biocide, a pour point depressant, and water, ethylene glycol, or a combination thereof.Type: GrantFiled: August 13, 2014Date of Patent: June 4, 2019Assignee: Houghton Technical Corp.Inventors: Douglas C.

Patent number: 9475116Abstract: Processes for die casting metals are provided, which are more energy efficient and less expensive than the current metal die casting processes. The die casting processes discussed herein utilize a water-soluble die release fluid and hydraulic equipment which uses water-insoluble hydraulic fluid. By doing so, the hydraulic fluid and die release fluid present in the waste collected from the die casting process can be collected via separation techniques. One or both of the collected hydraulic fluid and die release fluid may then be re-used in the same die casting process, another die casting process, or other processes altogether.Type: GrantFiled: March 23, 2012Date of Patent: October 25, 2016Assignee: Houghton Technical Corp.Inventors: John Michael Burke, Alan Edward Cross
