Abstract: An apparatus for mixing viscous fluids in a container through applied rotational and oscillation motions is provided. The apparatus has a sample carrier platform mounted to a shaft along a longitudinal axis with a first mechanism imparting oscillating motion to the shaft and a second mechanism imparting rotational motion to the shaft and carrier platform along the axis simultaneously or sequentially. Couplings to the shaft allow the shaft to freely rotate at the same time as it can be pushed or pulled along the longitudinal axis. Sequence, duration and frequency of oscillations and rotations are controlled with a programmable controller.

Abstract: There is disclosed a receiver panel. In an embodiment, the panel is configured to receive a curtain of particles in a solar central receiver system. A porous structure of the panel has a top end and a bottom end. The porous structure is disposed between the top end and the bottom end. The porous structure has a size to impede movement of the particles during downward travel from the top end to the bottom end. There is disclosed a solar central receiver system. In an embodiment, the receiver system includes a plurality of receiver panels, a tower supporting the plurality of receiver panels in a configuration to receive solar irradiation, and a hopper forming a slot configured to dispose the particles at a given location on to the porous structure. Other embodiments are also disclosed.

Abstract: An automated apparatus for removing the tops (calyx) of strawberries as they move along a conveyor belt having a plurality of concave-shaped slotted rollers which operate to orient the calyx of each strawberry for being cut. Images are captured and processed for locating the calyx of each strawberry and determining an optimal cutting plane. In response to the image processing a control system actuates a blade in a cutting apparatus to pass through the produce item and into one of the slots in a roller, or rollers, to separate the calyx from the body of the strawberry.
