Abstract: A harvesting device for separating round root crops, such as potatoes, from soil and other unwanted material. The crop and the soil in which it is growing is uplifted into the harvesting device by the forward movement of the device. The uplifted material is delivered into two conveyors, one positioned above the other and one running at a different speed from the other. The upper conveyor has a series of transverse members, such as fingers and flaps, which break up the uplifted material into discrete portions and these transverse members form with the lower conveyor a series of pockets so that each discrete portion of uplifted material lies in a pocket. The conveyors are inclined and this combined with the differential speed causes the material to be tumbled and the round root crops to roll free of unwanted material.

Abstract: Apparatus for removing trim from ends of elongate rolls, or logs, of paper cut into several short rolls of uniform lengths. The cut logs are transported longitudinally, in side by side disposition, while the short rolls are individually supported by first support members extending between and engaging confronting sides of the rolls, in combination with second support members opposite the first support members and engaging sides of the rolls opposite the sides engaged by the first members. The trim is not engaged or supported by the first and second members, and is permitted to fall away from the logs as they are transported.

Abstract: Apparatus for discarding leaky packages from a row of filled sealed packages on a conveyor belt comprising means for exerting pressure on the packages while on the belt and means for removing packages from the belt which appear to be leaky when subjected to said pressure, wherein said means for exerting pressure comprises the conveyor belt and a member located above said belt that in cooperation exert pressure on a package on the belt, either one of said member or belt being movable with respect to the other and the smallest distance between said belt and said member being chosen so that only a tight package is clamped therebetween while a leaky package is not, and said means for removing the leaky packages comprises a nozzle that blows air agains the packages in the space between said belt and member, whereby unclamped leaky packages will be removed from the conveyor belt.
