Abstract: A waste removal and/or segregation system for removing liquid and solid waste simultaneously from waste-holding tanks or vessels. The solid matter in the waste is filtered or segregated into one holding area and the liquid waste placed in a separate holding vessel so that each waste material may be independently disposed of in accordance with current EPA requirements. A separation or filtration element is interposed between a conventional liquid waste removal system including a container for the liquid waste and the nozzle applied to the waste material containing both solid and liquid matter. This vessel has an inlet connected to the nozzle and an outlet connected to the vacuum source through the liquid waste storage tank. The novel vessel of this invention has a filtration system that permits the liquid waste to exit for independent disposal while retaining solid matter for independent disposal.

Abstract: A separating and dispensing apparatus for small, rigid, elongate articles which continuously tumbles a mass of such articles to progressively separate articles from the mass and continuously dispenses the articles as separated.

Abstract: An electrically adjusted and mechanically driven variable speed pulley transmission provides immediate and accurate changes to the seed dispensing rate of a planter. The variable speed pulley transmission is driven by a ground-engaging wheel and adjusted in response to electrically monitored variations between desired and actual seed plant densities. Adjustment to the sheaves of the transmission pulley is effected by an electric motor and tension springs which interconnect the movable pulley sheaves apply pressure to the sides of the pulley belt to assure torque transmission at low RPM's.
