摘要： Disclosed herein are diatomite filter aid products with enhanced permeabilities and flow characteristics, and methods for enhancing the permeabilities and flow characteristics of very fine grain, low permeability diatomite ore by, in one embodiment, pre-agglomerating the ore in the presence of less than 10% water and then subjecting the pre-agglomerated ore to at least one calcination process. At least one flux may be used in the at least one calcination process. Also disclosed herein is a method of processing diatomite ore suitable for samples with high wet densities or large amounts of fine particulate matter. Also disclosed herein are methods of producing commercially applicable filter aid products from Hungarian diatomite.

摘要： A transceiver allowing transmission of a co-polar transmit signal and simultaneous reception of co-polar receive and cross-polar receive signals. An integrated orthogonal mode transducer and diplexer module containing a plurality of filters between a feed port, co-polar transmission port, co-polar reception port and cross-polar reception port is mounted within the transceiver housing with the feed port aligned with or forming the feed flange of the transceiver. A transmitter printed circuit board is aligned with the transmission waveguide port and a receiver printed circuit board is aligned with the co-polar reception and cross-polar reception ports of the integrated orthomode transducer and diplexer module.

摘要： An LNB for simultaneous reception of circular and linear polarization radio frequency signals, having a circular waveguide coupled to a waveguide to microstrip turnstile transition. The microstrip outputs coupled to a multi-layer printed circuit board having symmetrical signal paths on separate layers. Each symmetrical signal path including a first combiner coupled to a low noise amplifier that is coupled to a splitter. A first output of each of the splitters having a linear polarization and a second output of each of the splitters coupled to a branch line combiner having two outputs, each of the two outputs having opposite hands of circular polarization.
