Abstract: A mass flow meter includes an arcuate tube section that is semi-circular, an inner pressure sensor disposed on an inner curvature portion of the arcuate tube section and configured to capture an inner pressure measurement of the flowing fluid, an outer pressure sensor disposed on an outer curvature portion of the arcuate tube section and configured to capture an outer pressure measurement of the flowing fluid, and processing circuitry. The processing circuitry may be configured to receive the inner pressure measurement and the outer pressure measurement, determine a pressure difference between the inner pressure measurement and the outer pressure measurement, and determine a mass flow rate of the flowing fluid passing through the arcuate tube section based on the pressure difference and a fluid density of the flowing fluid.

Abstract: A distillation column including a plurality of alternating plates and spacers stacked in a z-direction is provided. The plates include a respective liquid channeling network on a top surface thereof, a respective vapor opening, and a respective descending ramp. The respective descending ramps abut a respective liquid feed location of the plate immediately below to form a continuous liquid channeling network. The respective vapor openings of adjacent plates are located on opposite sides of the distillation column and form a continuous S-shaped vapor channel defined by the plurality of alternating plates and spacers, and the respective vapor openings. Systems including such distillation columns and processes of distilling a fluid mixture are also provided.

Abstract: A reactor includes a first outer tube configured to contain a working fluid, and a first inner tube disposed in the first outer tube. The first inner tube is configured to contain a source of heat to transfer or absorb heat to or from the working fluid. The reactor further includes a second inner tube in the first outer tube. The second inner tube is wound around the first inner tube in a helical fashion, and the second inner tube is configured absorbs heat from and/or dissipates heat to the working fluid, and/or facilitate a reaction in a reactant contained in the second inner tube.

Abstract: A multi-sensor edge computing system can have at least a sensor assembly connected to an edge computing device and a downstream host. The sensor assembly may have a first sensor and a second sensor with the respective sensors being different. The edge computing device can be configured to identify a false reading of the first sensor in response to data captured by the second sensor.

Abstract: Aspects of the disclosure are directed to apparatuses and methods involving particulate sampling. As may be consistent with one or more embodiments, an apparatus includes a flow direction structure, a flow sampler and a particle collector having a collecting surface. The flow direction structure has interior sidewalls that direct the flow of particulate-laden gas along a flow path. The flow sampler is located in the flow path within the interior sidewalls, and operates with the flow direction structure to sample a portion of the particulate-laden gas at a reduced velocity, while allowing another portion of the particulate-laden gas to exhaust around the flow sampler. The flow sampler operates with the particle collector to direct the sampled portion of the particulate-laden gas to the collecting surface, and to adhere particulates from the particulate-laden gas to the collecting surface.

Abstract: Apparatus for merging a disc drive head disc assembly (HSA) with a disc stack. The HSA comprises a flexure which supports a data transducing head and the disc stack comprises a disc having a data storage surface. A merge assembly includes a shipping comb attached to the HSA, the shipping comb having a first alignment member and a first flexure support member. The merge assembly further includes a merge comb having a second alignment member and a second flexure support member. The merge comb is advanced by a robotic arm to a position where the second alignment member engages the first alignment member. This aligns the shipping comb with the merge comb and allows transfer of support of the flexure to the second flexure support member at an elevation suitable to subsequently pass the head in a safe, clearing relationship over the data storage surface.
