Publication number: 20190226961Abstract: A wear testing device includes a plurality of holding portions that hold rubber samples. The rubber samples held by each of the plurality of holding portions are independently and simultaneously pressed against a circumferential surface of a rotation body in rotation by a pressing mechanism so that abrasion debris of each of the rubber samples produced via this contact falls downward.Type: ApplicationFiled: May 16, 2017Publication date: July 25, 2019Inventor: Yuto Kitani

Publication number: 20190226965Abstract: Disclosed herein is a novel optical particle characterization system and method of use that can be applied to harsh environments. By separating the sensing components from the electronics unit and using optical fibers for interconnection, only the sensing components need to endure harsh environmental conditions. This reduces the design constraints on the electronics unit and permits the incorporation of optical components into the sensing probe that can withstand high-temperature and high-pressure environments.Type: ApplicationFiled: January 23, 2018Publication date: July 25, 2019Applicant: Hal Technology, LLCInventors: Hai Lin, Gregor Arthur Waldherr

Publication number: 20190226966Abstract: An apparatus for classifying fine particles in slurry provides a sharp particle size distribution with few mixed coarse particles and high classification accuracy. The apparatus includes a rotor (15) including classification chambers (17) between blades (16) radially arranged at circumferentially regular intervals, and classifies particles so that a classified particle size is constant in an entire radial region from an outer periphery to an inner periphery of the classification chamber. The blade (16) of the rotor has a circumferential thickness t(d) increasing toward the outer periphery, and the classification chamber (17) has a width increasing toward the inner periphery.Type: ApplicationFiled: January 8, 2019Publication date: July 25, 2019Inventors: Mitsugi INKYO, Makoto SATO, Masaaki OGIHARA

Publication number: 20190226967Abstract: Devices and methods are described for measuring formed blood component sedimentation rate. Some of the methods may use (1) centrifugal techniques for separating red blood cells from plasma and (2) video and/or still imaging capability. Both may be used alone or in combination to accelerate formed blood component sedimentation and to measure its rate. In one example, the method may advantageously enable rapid measurement of sedimentation rate using small blood sample volumes. Automated image analysis can be used to determine both sedimentation rate and hematocrit. Automated techniques may be used to compensate for effects of hematocrit on uncorrected sedimentation rate data.Type: ApplicationFiled: January 28, 2019Publication date: July 25, 2019Inventors: Mark Dayel, Samartha Anekal, Elizabeth A.

Publication number: 20190226968Abstract: An apparatus and method for condensationally enlarging particles in a flow of air or other gas. The apparatus includes a coiled tube having a tube diameter and a coil diameter, the tube having an input receiving the flow and an output, the tube having a length between the input and the output. The walls of the tube are wetted with a condensing fluid. The walls of the first portion of the coiled tube are held a temperature that is lower than the highest temperature in the second portion of the tube. The tube may have a third vapor recovery portion with wall temperature lower than the highest temperature in the second portion, and which optionally may not be coiled. While heating and cooling, the method includes introducing a flow into an interior of the tube at an input, the flow moving the output.Type: ApplicationFiled: April 2, 2019Publication date: July 25, 2019Applicant: AEROSOL DYNAMICS INC.Inventors: Susanne Vera Hering, Steven Russel Spielman, Gregory Stephen Lewis
