Patent number: 6254787Abstract: Provided is a method for preparing a fluid containing size-controlled particles that is optimized with respect to use of a target fluid as a matrix fluid under conditions approximating actual conditions. In a preferred embodiment, size-controlled SiO2 particles are obtained by mixing and dispersing SiO2 starting particles having various sizes in a N2 carrier gas followed by fractionation with a fractionator. The size-controlled particles are electrostatically collected by a porous member from the carrier gas flow. Ultrasonic vibrations are then applied to the porous member while a HCl matrix fluid flows through the porous member loaded with the size-controlled particles. This causes release of the size-controlled particles from the porous member and their admixture and dispersion into the HCl matrix fluid.Type: GrantFiled: April 20, 1999Date of Patent: July 3, 2001Assignee: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Masao Kimura, Itsuko Suzuki, Kohei Tarutani

Patent number: 6182519Abstract: Provided is a safe method for qualifying the cylinder valves on gas cylinders, which method can also clean the cylinder valve when necessary. Compressed gas residing in a gas cylinder is discharged through the flow path of a cylinder valve with the cylinder valve on the gas cylinder in an open position. During this process ultrasound vibrations from the generator are applied to the cylinder valve and the number of particles in the outflowing gas is counted by a detector. The cleanliness of the cylinder valve is evaluated based on the detected value of the number of particles provided by the detector. When the detected value exceeds a standard value, the application of ultrasound vibrations, counting of the number of particles, and evaluation of the cleanliness are repeated until the detected value reaches or falls below the standard value.Type: GrantFiled: March 16, 1999Date of Patent: February 6, 2001Assignee: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Masao Kimura, Kohei Tarutani
