A meter apparatus for dispensing agricultural products into a product conduit carrying a product air stream at a product air pressure. A sealed tank is pressurized to a tank pressure that is substantially equal to the product air pressure, and a meter roller mounted on a shaft is mounted in a housing below the sealed tank. A drive is operative to rotate the shaft and the meter roller. Clearance spaces are provided each side of the meter roller. Bearings mount the shaft to the housing, and seals are mounted to the shaft and to the housing between the right and left bearings and the meter roller. The housing defines right and left chambers between the seals and the meter roller. The purging conduit carries a purging air stream at a purging air pressure that is greater than the product air pressure into the chambers, and through the clearance space.

An improved modulated particulate metering system is provided. The system includes a plurality of particulate storage areas, each having a separate type of particulate. The system can include varied configurations of a plurality of cartridges in communication with one of the particulate storage containers. The system can further include varied configurations of a plurality of gearboxes operably connected to the cartridges. The gearboxes can be adapted to be inverted and operably controlled by one or more drive shafts. The system can still further include varied configurations of a plurality of particulate accelerators in fluid communication with an air flow path having one inlet. The system permits a user to efficiently alternate between desired configurations based on the needs of the application.

A bulk material tender is described. The bulk material tender includes a hopper. The hopper includes one or more side walls defining a top opening and a bottom opening. The bulk material may also include a frame connected to and supporting the hopper. The bulk material tender may also include a rotary airlock for receiving material from the hopper. The bulk material tender may also include a pneumatic conveyor coupled to the rotary airlock for conveying the material to a desired location. The bulk material tender may also include a slide gate valve between the rotary airlock and the hopper. The bulk material tender may also include support legs and jacks for self-loading and self-unloading from a vehicle.

A conveyor for pulverized material comprises in combination a conduit, a screw rotatably mounted within the conduit having an material inlet end and material discharge end, means for rotating the screw, means for supplying material to the screw at the material inlet end, whereby the material will be compacted as it is advanced by the screw to the material discharge end, and means for admitting a gas under pressure to the compacted material at the material discharge end to render it fluent. In a portion of the screw a material seal is formed by the compacted material being advanced by the screw, wherein there are material pockets formed between adjacent screw flights, wherein the pocket size volume is at its maximum nearest the material inlet end and at its minimum nearest the material outlet end, with at least twice as many pockets of minimum size as of maximum size.
