Abstract: A lotion saving device that includes a plurality of hollow threaded members, each of said hollow threaded members having a first threaded portion and a second threaded portion, a plurality of first threads disposed interiorly upon the first threaded portion and a plurality of second threads disposed interiorly upon the second threaded portion, the plurality of second threads disposed enantiomorphically with respect to the plurality of first threads, wherein an extant first lotion container is rotatably attachable to the first threaded portion and an extant second lotion container is rotatably attachable to the second threaded portion, said first lotion container thereby elevated and inverted relative said second lotion container, whereby lotion drains from the first lotion container and is collectable in the second lotion container.

Abstract: A method for screening fibrous stock slurry having a rotor impeller and a screen, in which accepts quality and throughput may be adjusted without stopping the screening process by relative displacement of the clearance between the rotor and the screen plate. In one version, this relative displacement is accomplished by axial displacement of frusto-conical portions of the bladed rotor and screen. The relative axial displacement changes the degree of pulp disturbance in a primary screening zone, thus causing throughput and accepts quality to change accordingly. The primary screening zone may be between the rotor impeller and the screen, or it may be on the other side of the screen, in which case the blades on the screen are designed to permit a portion of the pulp slurry to flow through the screen into a region between the rotor impeller and the screen.
