Abstract: A pin conveyor for pasty materials such as animal waste including a housing with a cylindrical inner surface extending along and about an axis. Within the housing surface, a shaft is mounted for rotation about the axis and has a plurality of pins attached to it in a substantially helical pattern. The pins have sleeve members slidably mounted about them wherein in operation, the sleeve members are centrifugally impelled outwardly of the pins to contact and scrape clean the housing surface as the shaft is rotated about the axis. The cylindrical outer surfaces of the sleeve members preferably overlap or are at least tangent to one another when viewed in a plane perpendicular to the rotational axis so as to effectively contact and scrape clean the entire housing surface surrounding them.

Abstract: Improvements in the sealing area and dynamic operation of liquid ring pumps. The sealing improvement involves providing aspirating means between the cone inlet and the fluid adjacent the shaft on the inboard or high pressure side of the sealing area. In operation, the high pressure fluid that would tend to leak past the seal in prior art to contaminate the bearings or create a potentially dangerous gas explosion is harmlessly aspirated off into the gas being drawn into the pump. Further, in doing so, the sealing properties of the pump seal are enhanced. The dynamic improvement is directed particularly to duplex liquid ring pumps and calls for the rotor blades on one side of the central partition to be offset or out of phase from the mirror-image rotor blades on the other side of the partition.
