20230046575, Feb 16, 2023

Filed:

Aug 12, 2022

Appl. No.:

17/819508

Inventors:

- Shoreview MN, US
Lin Li - Arden Hills MN, US

International Classification:

G05D 7/06

Abstract:

A fluid system includes a capillary and a first and second temperature sensor, a first and second pressure sensor, and a processor coupled to the sensors. The processor is configured to execute instructions to determine an output using the sensor data and using fluid parameter data received via an interface coupled to the processor. The processor is coupled to a control in fluid communication with the capillary.

Abstract:

Exemplary embodiments in desalination by direct contact membrane distillation present a cylindrical cross-flow module containing high-flux composite hydrophobic hollow fiber membranes. The present embodiments are directed to a model that has been developed to describe the observed water production rates of such devices in multiple brine feed introduction configurations. The model describes the observed water vapor production rates for different feed brine temperatures at various feed brine flow rates. The model flux predictions have been explored over a range of hollow fiber lengths to compare the present results with those obtained earlier from rectangular modules which had significantly shorter hollow fibers.

International Classification:

G01N 15/06

US Classification:

73 2802, 73 2804

Abstract:

An apparatus and method for sampling and measuring air born particulate matter includes an inlet for the particulate containing gas to enter. A mechanism then removes coarse particles larger than a selected size while permitting filtered particles of less than the selected size to pass through. A chamber containing a quartz crystal sensor permits the filtered particles that have passed through to deposit to create an output signal in response to the deposited particle mass.
