Abstract: An automated crop harvester includes: (a) a frame; (b) a drive system supporting the frame for movement of the frame along a ground surface in a harvesting direction; and (c) a plurality of articulated robot arms mounted to the frame and spaced laterally apart from each other generally perpendicular to the harvesting direction for harvesting crops in corresponding crop rows. Each robot arm has end-of-arm tooling automatically movable laterally relative to the frame into alignment with respective crops projecting from the ground surface for cutting and collecting the crops.

Abstract: A process and apparatus for increasing biological activity in waste treatment ponds and lagoons. In this process a floating fluid circulator having an annular space between nested frusto-conical surfaces is operated in a pond or lagoon. An aerator within the scope of the floating fluid circulator is provided. That aerator includes an upper float chassis having a frusto-conical configuration, a sectional diverter arranged in a lower portion of the upper float chassis, the sectional aerator having a lower diverter portion and motor driven means mounted on the upper float chassis connected to a rotatable impeller.

Abstract: A flow system for infusing a fluid such as blood from a storage reservoir into the human body includes a hand-operated pump for increasing the flow rate of the fluid through the system when required. The pump includes a duckbill-type valve assembly user-conditionable to an open position wherein fluid can pass freely through the valve and air trapped in the housing of the pump can be purged upline to the reservoir, and to a closed position wherein reverse flow of fluid in the system is prevented during operation of the pump.
