A meter roller for an agricultural metering system includes a first segment having a first set of flutes and a corresponding first set of recesses. The meter roller also includes a second segment having a second set of flutes and a corresponding second set of recesses. A first aggregate volume of the first set of recesses is substantially equal to a second aggregate volume of the second set of recesses, and a first longitudinal end of the first segment contacts a second longitudinal end of the second segment along a contact surface. In addition, the second segment is circumferentially offset from the first segment such that each flute of the first set of flutes is at least partially aligned with each recess of the second set of recesses at the contact surface.

The dispenser disclosed herein serves a single serving of a powdered nutrient contained within a container having multi-servings of the powdered nutrient. The dispenser has a metering device that operates as a ball valve or guillotine to dispense a single serving of the powdered nutrient into a water container. The dispenser also has a support surface that can be lowered and raised back up in order to fit a water container under the metering device and a distal tip of the metering device into a mouth of the water container so that no powdered nutrient spills out of the water container during transfer of the powdered nutrient from the metering device to the water container.

A spray system for applying an amount of a liquid to a material that is a function of the unit weight of the material as the material is moving via a conveyor system, the spray system includes a spray nozzle oriented to discharge liquid on the material being conveyed. A weight measurement system includes a first sensor and a second sensor. A programmable logic controller (PLC) configured to determine a total volume of material conveyed per a unit of time and determine a weight of the material being conveyed per the unit of time using a bulk density of the material being conveyed. A spray configured to vary a cycle of actuation of the spray nozzle between the closed and open positions to discharge a desired amount of the liquid based on the weight per unit time of the material being conveyed.

A system distributes raw material powder from a reservoir to a plurality of at least two additive manufacturing machines. The system includes at least one gas flow drive and at least two conveying lines for conveying the powder to the at least two manufacturing machines by a gas flow driven by the at least one gas flow drive. The system further includes a feeding manifold for feeding the at least two conveying lines with the raw material powder. The feeding manifold is configured and arranged to selectively guide, controlled by at shut-off valves, the raw material powder into one of the at least two conveying lines. Each of the shut-off valves is arranged at the feeding manifold and is configured to selectively close and open for selectively feeding the at least two conveying lines with the raw material powder.

A dispense tip constructed and arranged to communicate with a material dispensing pump comprises an elongated neck and a molded base having a first portion and a second portion opposite the first portion. The neck extends from the first portion of the base. The second portion is constructed and arranged to abut an outlet surface of the pump. An outermost region of the second portion of the base includes a compressible fluid-tight surface that compliantly conforms to the outlet surface when the dispense tip is mounted to the pump.

A particulate metering system includes an air flow origin and a plurality of particulate accelerators. A single particulate source is in communication with the particulate accelerators. Each of a plurality of operated conveyances can be in operable communication with the single particulate source and one of the particulate accelerators. The system includes a confluence of the air flow and the particulate within the mixing area of each of the particulate accelerators. Each of a plurality of discharges can be associated with the particulate accelerators. The operated conveyances can operate at different rates. The system can include one or more gearboxes adapted to be inverted and controlled by a second drive system. The system and controls provide variable application rates of particulate across rows in a field.

In one embodiment, the present disclosure includes a cloud computer system for controlling a plurality of remote devices comprising a cloud server including a cloud based operating system comprising a data model stored in a computer memory. The data model includes commands that may be performed by a plurality of remote devices in a remote system and, for each remote device, one or more operations for triggering processes executed by the remote device. The cloud based operating system generates a set of instructions from the plurality of commands and corresponding operations to control a portion of the remote devices to perform a task.

A device for metering granular or powered product having a meter housing, an auger housing positioned within the meter housing, the auger housing having an inlet opening for receiving the granular or powdered product, a rotatable spiral brush mounted within the auger housing, a first discharge outlet near one end of the auger housing for discharging granular or powdered product, and another opening near another end of the auger housing for discharging granular or powdered product not discharged through the first discharge opening. A method for metering granular or powdered product is also provided.

Pacifier devices with internal reservoirs and metering units are described. The metering units provide single dosages of an internal supplement material during a fixed period of time. For example, embodiments of pacifier devices can be utilized to provide supplemental nutrition paste or gel to undernourished infants with metered dosages as appropriate to the supplement.
