Abstract: A bulk materials pump feeder having a housing and a rotating drive rotor for transferring material from an inlet to an outlet of the housing. The drive rotor has a hub. Drive disks extend away from the hub toward a housing inner wall and have a compliant edge configured to deflect or compress when presented with pinched material rather than jamming.

Abstract: A bulk materials pump feeder having a housing and a rotating drive rotor for transferring material from an inlet to an outlet of the housing. The drive rotor has a hub. Drive disks extend away from the hub toward a housing inner wall. Three structural features of the feeder reduce the tendency of material to jam between the drive rotor and the housing or other stationary parts. First, the distance between the circumferential edges of the drive disks and the housing inner wall increases from the inlet to the outlet in the direction of rotation of the drive rotor. Second, a low-friction brush seal disposed on the periphery of the drive disks seals the area between the periphery of the drive disks and the inner wall. Finally, a materials scraper having a flexible tip is mounted in the housing and extends into the drive rotor between the drive disks.

Abstract: A system for managing vendor data, the system including a vendor component controlled by an owner and accessible to a vendor, wherein the vendor component is adapted to allow the vendor to enter vendor-supplied data describing the vendor, and further adapted to allow the vendor to update the vendor-supplied data; and an owner component associated with the vendor, controlled by the owner, and inaccessible to the vendor, wherein the owner component is adapted to allow the owner to enter owner-supplied data describing the vendor, and further adapted to allow the owner to review the vendor-supplied and owner-supplied data.
