Abstract: The present disclosure relates to an improved sieve tray assembly for a liquid-liquid treating column. The tray is a modular design with inlet and outlet downcomer assemblies that are mounted flush to or raised above the sieve deck upper surface. The raised downcomer assemblies provide increased surface area for light liquid upflow perforations and enhanced liquid-liquid contacting capacity and efficiency.

Abstract: A shoe insole includes photoplethysmography (PPG) sensors to monitor SpO2 levels to aid in detection of one or more disorders such as hypoxemia, deteriorating organ function, wound prone tissues or the like. The insole further includes electrodes that may be utilized to stimulate a foot at or adjacent a wound. An insole according to the present disclosure may be utilized to monitor diabetic wounds, and aid in the healing of diabetic wounds of a foot.

Abstract: A method of inspecting a separation vessel may utilize off axis gamma scanning. During scanning, a gamma radiation source can emit gamma radiation through a separation vessel toward a detector, and the detector can detect radiation emitted by the gamma radiation source and passing through the separation vessel. The gamma radiation source may be positioned at a first vertical elevation along the separation vessel and the detector positioned at a second vertical elevation along the separation vessel different than the first vertical elevation. As a result, a radiation path may be defined between the gamma radiation source and the detector that transects the separation vessel at a non-zero degree angle with respect to a horizontal plane.
