The method includes measuring an amount of increase of a dissolved oxygen concentration of the cleaning liquid resulting from an oxygen molecule generated from a water molecule as a result of a radical reaction caused by ultrasonic wave irradiation. A dissolved nitrogen concentration of the cleaning liquid is calculated from the measured amount of increase of dissolved oxygen concentration based on a predetermined relationship between a dissolved nitrogen concentration and an amount of increase of dissolved oxygen concentration.Type: GrantFiled: December 13, 2011Date of Patent: July 15, 2014Assignee: Siltronic AGInventors: Teruo Haibara, Etsuko Kubo, Yoshihiro Mori, Masashi Uchibe

Publication number: 20140137635Abstract: A canister for measuring the natural gas content of rock cores which (1) has an inner core-containment bag made of non-permeable plastic which can be flash evacuated, collapsing around the core and thus minimizing the amount of air present and improving the quality of the gas analyses and (2) which prevents the released gas from reacting with the outer canister. A procedure for using gas-sampling bags to periodically collect the gas released from the core so that (1) the volume of released gas can be measured at a later date using more convenient and precise laboratory methods, (2) the gas can be readily transported and stored, and (3) the gas can be easily submitted for analysis.Type: ApplicationFiled: September 3, 2013Publication date: May 22, 2014Applicant: Isotech Laboratories, Inc.Inventors: Dennis D.

Patent number: 8713988Abstract: A technique related to a fermentation process; where a signal processor receives a signal containing information about an amount of entrained air in a mixture forming part of a fermentation process in a tank; and determines a level of foam in the tank based at least partly on the amount of entrained air in the mixture. The signal processor may also provide a control signal for controlling an amount of defoamer (or antiforming agent) added to the mixture in the tank so as to control the production of foam within the tank by controlling the amount of defoamer added to the mixture in the tank.Type: GrantFiled: February 16, 2010Date of Patent: May 6, 2014Assignee: CiDRA Corporate Services Inc.Inventor: John Biesak

Patent number: 8479563Abstract: Systems and methods are provided for measuring the permeance of a material. The permeability of the material may also be derived. Systems typically provide a liquid or high concentration fluid bath on one side of a material test sample, and a gas flow across the opposing side of the material test sample. The mass flow rate of permeated fluid as a fraction of the combined mass flow rate of gas and permeated fluid is used to calculate the permeance of the material. The material test sample may be a sheet, a tube, or a solid shape. Operational test conditions may be varied, including concentration of the fluid, temperature of the fluid, strain profile of the material test sample, and differential pressure across the material test sample.Type: GrantFiled: April 3, 2012Date of Patent: July 9, 2013Assignee: Babcock & Wilcox Technical Services Y-12, LLCInventors: Russell Louis Hallman, Jr., Michael John Renner
