  • Patent number: 11105779
    Abstract: A pressure system for liquid chromatography allows multiple fluid lines to be driven in parallel by a single pump. A fluid pressure medium supply provides fluid pressure to the system. The fluid pressure medium supply is connected to a plurality of fluid transfer pipes, each with a flow limiter. The fluid pressure medium supply is configured to provided more flow than the flow limiters combined, and excess flow is either diverted with a pressure limiter or reduced with a pressure adjuster, or both. Further layers of pressure and flow control may be added with additional pressure limiters and/or pressure adjusters and flow limiters connected together. In some cases, multiple lines containing different fluids may be driven by the same pressure source through the use of flexible fluid delivery inner containers, each within a rigid container that is pressurized by the pressure source.

  • Patent number: 11099587
    Abstract: A waste oil transfer system includes a system controller configured to determine the authorization status of a waste oil transfer request. The system controller requests a current fluid level in a storage tank from a tank level monitor mounted on the storage tank. The tank level monitor is configured to generate current fluid level information and provide that information to the system controller. The system controller determines the available space in the storage tank and compares the available space to the transfer volume to determine if the storage tank can receive the transfer volume. The system controller then activates a pump to initiate the transfer if the system controller determines that the transfer is authorized or denies the transfer.

  • Patent number: 11092290
    Abstract: An amount Y of liquid hydrogen that has passed through a first valve and has been volatilized during a predetermined time after first and second valves are opened is calculated by using a pressure P0 in an internal space of a liquid hydrogen tank measured before the two valves are opened, a pressure P1 in the internal space measured after the lapse of the predetermined time since the two valves are opened, and an amount X of the gaseous hydrogen that has passed through the second valve during the predetermined time. A fluid level H of the liquid hydrogen in the liquid hydrogen tank after the lapse of the predetermined time since the two valves are opened is calculated by using a expression showing a relationship between the H and an amount Y1 of the liquid hydrogen that passes through the first valve and drops therefrom, and the Y.

  • Patent number: 10870091
    Abstract: A system for dissolving solid chemical may include three reservoirs positioned in a vertically stacked arrangement. A solid chemical reservoir configured to receive solid chemical to be dissolved may be nested in a solution generator reservoir into which water is introduced to erode the solid chemical. A dissolved chemical reservoir can be positioned under the solid chemical reservoir and the solution generator reservoir. The dissolved chemical reservoir can store solution generated using the system. In some examples, a recirculation circuit is used to recirculate water introduced into the solution generator reservoir until a solution having a target concentration of the chemical being dissolved is achieved. The recirculation circuit may include a recirculation line having an outlet aimed at the bottom wall of the solid chemical reservoir.

  • Patent number: 10865440
    Abstract: This disclosure provides an integrated and automated sample-to-answer system that, starting from a sample comprising biological material, generates a genetic profile in less than two hours. In certain embodiments, the biological material is DNA and the genetic profile involves determining alleles at one or a plurality of loci (e.g., genetic loci) of a subject, for example, an STR (short tandem repeat) profile, for example as used in the CODIS system. The system can perform several operations, including (a) extraction and isolation of nucleic acid; (b) amplification of nucleotide sequences at selected loci (e.g., genetic loci); and (c) detection and analysis of amplification product. These operations can be carried out in a system that comprises several integrated modules, including an analyte preparation module; a detection and analysis module and a control module.

  • Patent number: 10801640
    Abstract: An overfill-prevention valve system includes a testing mechanism, operable by a user from the inlet end of the drop tube, which can be used to verify proper valve function without actually filling the storage tank. The testing mechanism allows the user to actuate the valve manually using a test probe, such as by elevating a float to simulate a full storage tank. The testing mechanism may be located upstream of the valve to facilitate the testing operation without interfering with the valve body. The mechanism may further provide non-contact functionality, such as with magnetic actuators on either side of the drop tube wall, to eliminate a potential test mechanism leak points. The test probe used to actuate the test mechanism may be shaped to define a desired rotational position at the test location within the drop tube, ensuring proper rotational alignment of the magnetic actuators.
