Abstract: Assembly for regulating flow of hops into a fermentation vessel includes a hollow cross-shaped connector including a first cylindrical housing intersecting a second cylindrical housing at an approximate right angle. A rotary shaft coaxially mounted within the first cylindrical housing supports a hub and uniformly spaced vanes at a proximal end with outer ends of each vane adapted to sweep in close engagement with an inner wall of the first cylindrical housing. An actuator coupled to a distal end of the shaft is configured to control rotation of the shaft to control flow of hops from a hopper configured for holding hops into a hatch of a fermentation vessel configured for holding fermenting fluid. An outlet of the second cylindrical housing sealably connects to the hatch of the fermentation vessel, and an inlet of the second cylindrical housing sealably connects to an aperture of the hopper.

Abstract: Devices, methods, and computer program products providing user interfaces for visualization of user inputs may include generating a dynamic visualization interface for display, the dynamic visualization interface including indicia of selection, respective ones of the indicia of selection corresponding to variables associated with at least one contract; a plurality of increasing numbers corresponding to one or more of the indicia of selection; and a graphical indication that indicates a plurality of magnitudes of values that are dependent on the indicia of selection, monitoring one or more input devices of the computer system for adjustment to the one or more of the indicia of selection, and responsive to the adjustment to the indicia of selection, regenerating the dynamic visualization interface to reconfigure the graphical indication to adjust respective ones of the plurality of magnitudes of the values for respective ones of the plurality of increasing numbers.
