A conveyor having a conveyance structure, mixing components, belt, and gas manifold. The gas manifold disposed within or on an exterior portion of the structure. The gas manifold having one or more manifold outlet ports to dry, condition, or treat a metered stream of seed within the conveyor. The manifold may be operably connected to a recirculating air system providing the vacuum source and pressurized air source of atmospheric or conditioned air. A filter and vacuum port may extract debris or humidity from the metered stream of seed within the conveyor. A plurality of mixing baffles may be longitudinally spaced apart through the conveyor in a laterally alternating manner to mix the metered stream of seed. The conveyor may be used to transfer, mix, dry, condition and treat the metered stream of seed between multiple stages of treatment.

A process is described that includes flowing a carrier fluid through a transfer line, feeding polymer pellets into the transfer line at a feed location, measuring a first pressure value of the carrier fluid at a location in the transfer line upstream of the feed location, measuring a second pressure value of the carrier fluid and polymer pellets at a downstream location in the transfer line which is downstream of the feed location, and determining a mass flow rate of the polymer pellets flowing in the transfer line based on a differential pressure between the first pressure value and the second pressure value.

Provided are a thermally conductive ceramic-polymer composite in which thermoplastic polymers form a matrix, and planar fragments of thermally conductive ceramic or thermally conductive ceramic powder is uniformly dispersed on a grain boundary between thermoplastic polymer particles, thereby forming a thermal pathway, wherein the thermoplastic polymer particles are formed in a faceted shape, and the average size of the planar fragments of thermally conductive ceramic or thermally conductive ceramic powder is smaller than 1/10 of that of the thermoplastic polymer particles, and a method of preparing the same. Accordingly, since dispersion and interfacial affinity of a thermally conductive ceramic filler are maximized, excellent electrical insulation and excellent thermal conductivity can be exhibited even with a small content of the thermally conductive ceramic filler.
