Abstract: Disclosed are embodiments of a round floor grommet and a rectangular floor grommet. These floor grommets can be constructed in any desired shape other than round or rectangular. Frame portions that hold foam pieces are joined together to form a primary slit in the floor grommet. Cross slits can also be formed in the foam material. The foam is a semi-closed cell foam that is constructed from PVC and nitrile butadiene rubber which has superior sealing effects since the foam can conform around objects passing through the slits in the floor grommet and seal any flow of air through the slits.

Abstract: Curatives and their resulting thermosets and other crosslinked polymers can reduce thermal expansion mismatch between an encapsulant and objects that are encapsulated. This can be accomplished by incorporating a negative CTE moiety into the thermoset resin or polymer backbone. The negative CTE moiety can be a thermal contractile unit that shrinks as a result of thermally induced conversion from a twist-boat to chair or cis/trans isomerization upon heating. Beyond CTE matching, other potential uses for these crosslinked polymers and thermosets include passive energy generation, energy absorption at high strain rates, mechanophores, actuators, and piezoelectric applications.

Abstract: The present invention discloses an external loop slurry reactor, comprising a gas-liquid integrated distributor, a riser, a degassing zone, a solid-liquid separation circulation unit, and a storage tank. When the reactor works, reactants are injected into the riser through the gas-liquid integrated distributor; the slurry mixes and flows upwards to the degassing zone at the top for gas removal, and a large number of bubbles are removed. The slurry with catalyst particles then enters a downcomer and flows downwards. The slurry flows into a first-stage hydrocyclone and a multi-stage hydrocyclone in sequence for solid-liquid separation. The diameter of the first-stage hydrocyclone is larger than that of the multi-stage hydrocyclone. The separated solid particles flow back into the riser to continue to participate in the reaction.

Abstract: Proppant particulates are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. In complex fracture networks, it can be difficult to deposit proppant particulates fully within the fractures. In addition, low crush strengths may result in problematic fines formation. Polyaromatic hydrocarbons, commonly encountered in various refinery process streams, may serve as an advantageous precursor to proppant particulates. Polyaromatic hydrocarbons may undergo crosslinking under acid-catalyzed conditions in an aqueous solvent in the presence of a surfactant to form substantially spherical particulates that may serve as effective proppant particulates during fracturing operations. In situ formation of the proppant particulates may take place in some cases.

Pre-calculation of secondary aggregated values and/or secondary aggregated data sets for sequence-dependent data can allow the efficiencies of parallel or distributed computation to be at least partially retained while also allowing for desired processing of the sequence-dependent data.
