20090014391 | Buoy Suspension Fractionation System - A separator that uses centrifugation to fractionate a suspension such as blood comprises a separation container and a buoy. The buoy is carried in the separation container and has a tuned density that is configured to reach an equilibrium position in a suspension. The guide surface is carried on the buoy upper surface and is inclined to an accumulation position near a buoy perimeter. The buoy suspension fractionation system can be used in a method of isolating a fraction from a suspension, and in a method for re-suspending particulates for withdrawal. | 01-15-2009 |
20090045142 | METHOD AND APPARATUS FOR COLLECTING POLLUTANTS IN A BODY OF WATER - During collection of pollutants having a density lower than that of water and carried by a surface layer of a body of water, water of the surface layer is caused to flow into and through a collection vessel having a separation compartment with a top wall, pollutants entrained by the inflowing surface layer water are allowed to collect gravimetrically as a supernatant layer carried beneath the top wall of the separation compartment on water in the separation compartment, and changes of the weight of the collection vessel in the body of water are monitored. Intake and discharge phases may be initiated and terminated to in response to the said weight reaching predetermined values. | 02-19-2009 |
20100012592 | Method for Controlling a Blood Processing System by Observing a Separation Region and an Extraction Port - The invention relates generally to methods of monitoring and controlling the processing of blood and blood samples, particularly the separation of blood and blood samples into its components with a two-dimensional optical measurement and control device. The method may comprise the steps of providing a blood processing system comprising a density centrifuge blood processing system and an elutriation blood processing system; filling the elutriation blood processing system with a desired component; measuring a cellular flux of cells entering the elutriation blood processing system with a two-dimensional optical control system; and flushing the elutriation blood processing system. | 01-21-2010 |
20100025336 | Predictive Method for Controlling a Blood Processing System - The invention relates generally to methods of monitoring and controlling the processing of blood and blood samples, particularly the separation of blood and blood samples into its components. In one aspect, the invention relates to optical methods for measuring two-dimensional distributions of transmitted light intensities, scattered light intensities or both from a separation chamber of a density centrifuge. The method may include performing first and second measurements of an operating condition; analyzing the first and second measurements using a predictive data analysis algorithm; comparing the predicted operating condition to a desired operating condition; and adjusting at least one setting. | 02-04-2010 |
20100038321 | GRIT CHAMBER AND A METHOD FOR CONTROLLING THE SAME - A system for controlling the sedimentation of sand or grit particles suspended in waste water contained in a grit chamber by determining the temperature of water contained in the grit chamber and by operating a turbulence creating means on the hasis of the water temperature. A method of controlling the sedimentation of sand and grit particles suspended in waste water contained in a grit chamber, by determining the temperature of water contained in the grit chamber and by operating a turbulence creating means on the basis of the water temperature. | 02-18-2010 |
20110068061 | Integrated Measurement System For Use with Surgical Fluid Salvage Containers - A reservoir for use with a blood collection system includes a housing, a pre-filter, and a spring mechanism. The housing defines a cavity and has an inlet for receiving fluid from a source. The pre-filter is located within the cavity, removes particulates contained within the fluid, and allows the fluid to pass through the pre-filter. The spring mechanism is connected to the pre-filter and allows the pre-filter to travel within the cavity as the pre-filter collects particulates. | 03-24-2011 |
20120091067 | Fixation Filter Assembly - A filter assembly is provided for collecting samples in a fluid environment, the assembly utilizing a laminar convective flow to cause the flow of a preservative/fixative and a filtrate through a filter. A substantially concave dead space around the filter is flushed free of the preservative and the differential in density of the preservative and filtrate causes the more dense fluid to collect in the reservoir and preserve the collected specimen. | 04-19-2012 |
20130118991 | PROCESS AND APPARATUS FOR CONTROLLING A FILTRATION PLANT - A process and an apparatus are provided for controlling a filtration plant having at least one vacuum filter, at least one vacuum pump and at least one filter tank, by which a medium that is to be filtered and that includes solid particles and liquid is separated into a concentrate including predominantly solid particles and a filtrate comprising predominantly liquid. The method may include: determining at least one first parameter of the filtration plant in the form of a residual moisture content of the concentrate and/or of a density of the filtrate as a function of time or a second parameter of the filtration plant, forming a derivative of the at least one first parameter after the time or the second parameter as at least one first characteristic, determining the sign of the at least one first characteristic, and controlling the filtration plant as a function of the determined sign. | 05-16-2013 |
20160023131 | METHOD AND APPARATUS FOR REMOVAL OF SURFACE SCUM - A method for removing surface scum in a processing space. The surface scum is collected from a liquid surface with a surface scraper. The surface scraper includes at least one rotating surface scraper and a surface scum remover arranged above the liquid surface and including at least one outlet. The surface scum is guided to the outlet with a guide part arranged at an end of the surface scraper and passing over the outlet while passing along guide surfaces extending above the liquid surface. A closer arranged at a front edge of the surface scum remover is opened and closed. The closer is opened and closed before the guide part of the surface scraper enters the point of the front edge of the surface scum remover. The surface scum is guided to the outlet opening of the surface scum remover utilizing surface liquid when the closer is opened. | 01-28-2016 |
20160090799 | SMART SHAKER ROOM - This disclosure is generally drawn to systems, devices, apparatuses, and/or methods, related to monitoring a shaker used for separating solids from fluid. Specifically, the disclosed systems, devices, apparatuses, and/or methods relate to controlling an actuated arm to inspect, remove, replace, repair, clean, and/or install screen assemblies based on monitoring the shaker and its screen assemblies. In some examples, a system may include an actuated arm, a monitoring tool, and a controller. The actuated arm may be adjacent a shaker for separating one or more solids from a fluid. The monitoring tool may be coupled to the actuated arm and may monitor a screen assembly in the shaker. The controller may be in electrical communication with the actuated arm and the monitoring tool, and may control the actuated arm based on the monitoring of the screen assembly. | 03-31-2016 |
