Abstract: A conveying system (22) transports loose particulate material past a radiation source (200). A feed system (20) discharges particulate material onto the conveying system (22). A pneumatic system with an inlet manifold (14) and tubes (16) provides air through which the particulate material is fluidly transported to the feed system (20). A receiving hopper (24) receives the particulate matter from the conveying system (22). A dump hopper (10) dumps the particulate material into the pneumatic system. A discharge manifold (18) separates the particulate material from air. A metering gate (70) is located at a base of a hopper (69), which controls the layer of particulate material deposited onto said conveyor. A second inlet manifold (26) and tubes (28) adjacent the receiving hopper entrains the particulate material in air. A receiving station (32) receives the particulate material from a second discharge manifold (30).

Abstract: A high percentage bandwith microwave filter network, according to an embodiment of the present invention, comprises a T-network of capacitors implemented with thin-film techniques by applying a groundplane to one side of an alumina substrate and a first plate to the other side. A silicon nitride dielectric layer having a high density of capacitance is deposited over the first plate, and then a second and third capacitor plate are deposited on the dielectric over the first plate.

Abstract: A thin-film, lumped element filter utilizing spiral inductors and capacitive pi networks is disclosed. The filter is fabricated from a planar dielectric substrate having a ground plane on one side thereof and two thin-film metal layers and an insulation layer disposed therebetween on the opposite side of the dielectric substrate. The metal and insulation layers are configured to form one or more capacitive pi networks and spiral inductors, which are electrically interconnected to form the filter.
