  • Patent number: 11957828
    Abstract: Blood is conveyed from a source into a separator, which separates at least one target blood component from the blood. The target blood component is then conveyed out of the separator, with the procedure continuing until an initial target amount of blood to be processed has been conveyed from the source into the separator and the target blood component separated from the initial target amount of blood to be processed has been conveyed out of the separator as an actual yield of the target blood component. An adjusted target amount of blood to be processed is then determined based at least in part on the difference between a target yield of the target blood component and the actual yield. The initial target amount of blood to be processed is then replaced with the adjusted target amount of blood to be processed when next executing the procedure.

  • Patent number: 11951580
    Abstract: A coolant processing apparatus removes sludge from a coolant discharged from a machine tool. The coolant processing apparatus includes a first reservoir and a second reservoir provided in a tank for retaining the coolant. The first reservoir includes a flow path in which the discharged coolant flows, and a portion downstream of the flow path to retain the coolant such that the sludge remains in the first reservoir. The flow path has at least one bend to bend a flow of the coolant at least once in a horizontal direction. The second reservoir retains the coolant flowing out from the first reservoir. A boundary wall is provided between the first and second reservoirs, at a location downstream of the at least one bend of the flow path, and has such a height that allows a supernatant of the coolant in the first reservoir to flow into the second reservoir.

  • Patent number: 11938423
    Abstract: The present invention provides a system and methods for filtering fluid using filter papers, stationary paper, cloth sheets or any other porous material. In one embodiment, the present invention uses the lateral flow direction along the porous sheets, instead of conventional vertical flow direction, for the removal of bacteria and particle contamination in the range from nanometers to millimeters. The pore sizes in the filter media along the lateral direction are modulated by controlling the compression of the porous sheets, instead of conventionally designing filters with different pore sizes. The lateral flow fluid filter system is scalable simply by increasing the feed area, feed length, and the number of porous sheets. The invention presents a universal fluid filtration system for wide range of applications such as water purification, food processing, chemical industry, oil and gas industry, and biological applications.

  • Patent number: 11918936
    Abstract: The present disclosure discusses a method of separating a sample including oligonucleotides including coating a flow path of a chromatographic system; injecting the sample comprising oligonucleotides into the chromatographic system; flowing the sample through the chromatographic system; and separating the oligonucleotides. In some examples, the coating of the flow path is non-binding with respect to the analyte, such as oligonucleotides. Consequently, the analyte does not bind to the coating of the flow path. The non-binding coating eliminates the need for passivation, which can eliminate the formerly needed time to passivate as well. In addition, analyte can be recovered with a first injection in a system, such as chromatographic system.

  • Patent number: 11826677
    Abstract: Blood in a separation chamber is separated into a red blood cell layer, a plasma constituent, and a mononuclear cell-containing layer. A portion of the plasma constituent exits the chamber via a plasma outlet, while a first portion of the red blood cell layer exits via a red blood cell outlet. A second portion of the red blood cell layer exits the chamber via the red blood cell outlet and is collected. At least a portion of the collected red blood cell layer may then be conveyed to the chamber via the red blood cell outlet to convey at least a portion of the mononuclear cell-containing layer out of the chamber via the plasma outlet for collection. A second portion of the plasma constituent may be conveyed out of the chamber via the plasma outlet to more fully collect the mononuclear cell-containing layer without the use of collected plasma.
