  • Publication number: 20200390046
    Abstract: Hydroponics systems and apparatus for operation in zero-gravity and low-gravity environments are disclosed herein. An apparatus can include an elongated main body having an inlet end, an outlet end, and a channel disposed between the inlet end and the outlet end. The channel can include a first portion, and a second portion. The first portion can include surfaces that are inwardly tapered in a direction from the second portion to the first portion. The second portion can include at least one opening such that a portion of a plant can extend through the at least one opening. Fluid can flow through the channel.

  • Patent number: 9962024
    Abstract: A capillary beverage cup comprises a continuous interior corner extending from a lip interface into an inner cavity of the capillary beverage cup, the continuous interior corner comprising an acute included angle which tapers continuously as the interior corner approaches the lip interface. The capillary beverage cup provides a continuous capillary force on the liquid contained by the cup, allowing for complete withdrawal of fluid from the cup in low or near zero gravity environments, while enabling the cup to have an open top, allowing for aromatics to be experienced by a user while drinking with reduced concerns of spilling or release free-floating spheres of liquid in the low-gravity environment.

  • Patent number: 7913499
    Abstract: A heat exchanger having a plurality of heat exchanging aluminum fins with hydrophilic condensing surfaces which are stacked and clamped between two cold plates. The cold plates are aligned radially along a plane extending through the axis of a cylindrical duct and hold the stacked and clamped portions of the heat exchanging fins along the axis of the cylindrical duct. The fins extend outwardly from the clamped portions along approximately radial planes. The spacing between fins is symmetric about the cold plates, and are somewhat more closely spaced as the angle they make with the cold plates approaches 90°. Passageways extend through the fins between vertex spaces which provide capillary storage and communicate with passageways formed in the stacked and clamped portions of the fins, which communicate with water drains connected to a pump externally to the duct. Water with no entrained air is drawn from the capillary spaces.

  • Patent number: 7905946
    Abstract: Apparatus and methods for separating a fluid are provided. The apparatus can include a separator and a collector having an internal volume defined at least in part by one or more surfaces narrowing toward a bottom portion of the volume. The separator can include an exit port oriented toward the bottom portion of the volume. The internal volume can receive a fluid expelled from the separator into a flow path in the collector and the flow path can include at least two directional transitions within the collector.

  • Patent number: 6435274
    Abstract: A pulse thermal loop heat transfer system includes a means to use pressure rises in a pair of evaporators to circulate a heat transfer fluid. The system includes one or more valves that iteratively, alternately couple the outlets the evaporators to the condenser. While flow proceeds from one of the evaporators to the condenser, heating creates a pressure rise in the other evaporator, which has its outlet blocked to prevent fluid from exiting the other evaporator. When the flow path is reconfigured to allow flow from the other evaporator to the condenser, the pressure in the other evaporator is used to circulate a pulse of fluid through the system. The reconfiguring of the flow path, by actuating or otherwise changing the configuration of the one or more valves, may be triggered when a predetermined pressure difference between the evaporators is reached.

  • Patent number: 5127471
    Abstract: A pulse-thermal pump having a novel fluid flow wherein heat admitted to a closed system raises the pressure in a closed evaporator chamber while another interconnected evaporator chamber remains open. This creates a large pressure differential, and at a predetermined pressure the closed evaporator is opened and the opened evaporator is closed. This difference in pressure initiates fluid flow in the system.
