Abstract: An extraction module includes an axial chamber positioned about a central axis; and a plurality of extraction leaves arranged in a stack. Each extraction leaf extends outward from the central axis in a radial curvature and includes a porous active layer, a first nonporous backing layer, a first porous spacer layer disposed between the porous active layer and the first nonporous backing layer, a second porous spacer layer disposed on the porous active layer on a side opposite the first porous spacer layer, and optionally, a second nonporous backing layer disposed on the second porous spacer layer on a side opposite the porous active layer. The extraction module can be particularly useful for extraction of a target species from a fluid.

Abstract: A trailer for transporting a commodity includes a tank defining a chamber that is configured to receive the commodity and a discharge hopper located vertically below the chamber and configured to receive the commodity from the chamber. The discharge hopper includes a trough wall that at least partially defines a channel and the trough wall has a middle wall section and a side wall section surface on each lateral side of the middle wall section. Each side wall section is vertically located above the middle wall section. A floor auger extends in the channel and configured to convey the commodity toward the rear end. A hanger suspends the floor auger relative to the channel, and the hanger having a first hanger arm that couples to one of the side wall sections and a second hanger arm that couples to the other of the side wall sections.

Abstract: A process for producing methyl methacrylate by oxidative esterification in a reactor system comprising one or more reactors is disclosed. The process comprises feeding methanol, methacrolein, and an oxygen containing gas to a first reactor. The first reactor comprises a heterogeneous noble metal-containing catalyst. A base material is introduced at a position external to the first reactor and the base material is mixed with one or more reactants to form a base-containing stream. The base-containing stream is fed to the first reactor, wherein the pH in the first reactor is between 4 and 10.

Abstract: A duckbill assembly for a round baler is disclosed including first and second opposed elongate plates, the opposed elongate plates being directed towards one another so as to grip a portion of a wrapping material between the opposed elongate plates, wherein a portion of the first of the opposed elongate plates is formed of a manually displaceable material. This has as an advantage that the act of threading wrapping material into and through the duckbill assembly simply entails pulling the manually displaceable portion away from the opposing elongate plate, and dropping the wrapping material between the two elongate plates.

Abstract: A gate assembly comprising of a track comprising a vertical portion and two angular portions on opposing sides of the hopper. A pair of rectangular gates each comprising a longitudinal edge and opposing lateral edges slidingly engaged on the track allows the gates to move between a lowered, closed position and a raised, open position. A hinge combines the longitudinal edge of each of the pair of rectangular gates and allows them to pivot toward and away from each other during closing and opening, respectively.

Abstract: A system for automatically opening a lid to a grain bin with controller in communication with an actuator for receiving a signal containing a data packet to activate the actuator. An RFID is combined to an unloading device for transmitting the data packet to the controller when the RFID is positioned proximate to the controller. The controller compares the device id with a stored identification value and upon a match the controller activates the actuator to open the lid of the grain bin.

Abstract: A method for preparing methyl methacrylate from methacrolein and methanol; said method comprising contacting in a reactor a mixture comprising methacrolein, methanol and oxygen with a catalyst bed of heterogeneous catalyst comprising a support and a noble metal, wherein base is added to the reactor while maintaining time to reach 95% homogeneity at no greater than 10 minutes.

Abstract: A method for preparing methyl methacrylate from methacrolein and methanol; said method comprising contacting in a reactor a mixture comprising methacrolein, methanol and oxygen with a catalyst bed of heterogeneous catalyst comprising a support and a noble metal, wherein mass transfer rate of oxygen in hour?1 divided by space-time yield in moles methyl methacrylate/kg·catalyst hour in the catalyst bed is at least 20.
