Abstract: A valve arrangement for a wellhead of a hydrocarbon well comprises a valve for mounting in a port of a wellhead, and an actuator device for actuating the valve to move to an open position. The actuator device comprises a housing having a through channel extending between a first end, at which the valve is mounted, and a second end. The housing comprises at least one first port that leads into the through channel. The actuator device further comprises an actuator rod that is movably arranged in the through channel and configured to open the valve by the actuator rod being movable between at least a first position and a second position, and a control device arranged to control the movement of the actuator rod.

Abstract: The present disclosure relates to safety devices and systems for light mobility vehicles. In one example, a safety device for a light mobility vehicle includes a circuit board, one or more connectivity modules coupled to the circuit board, and an antenna coupled to the circuit board. The circuit board may be positioned within or coupled to a light mobility vehicle part. The antenna is configured to mitigate interference of one or more components of the light mobility vehicle part with the one or more connectivity modules.

Abstract: The present disclosure relates to safety systems, devices, and methods. In one example, a safety system includes a safety device in communication with a server. The safety device includes a processing element and a connectivity module configured to receive object data from a connectivity device within a short-distance range. The processing element is configured to analyze the object data to determine one or more safety risks and to transmit one or more alerts or safe routes based on the one or more safety risks. The server is configured to receive entity data from the safety device, receive safety-related data from one or more data sources, compare the entity data to the safety-related data to determine relevant safety-related data, and transmit the relevant safety-related data to the safety device. The processing element is further configured to incorporate the relevant safety-related data into the determination of the one or more safety risks.

Abstract: The present disclosure relates to safety devices and systems for light mobility vehicles. In one example, a light mobility vehicle safety system includes one or more sensors and a processor coupled to a light mobility vehicle. The processor may be configured to determine that the light mobility vehicle is part of a group of two or more light mobility vehicles; determine a position of the light mobility vehicle relative to one or more other light mobility vehicles in the group; determine one or more relevant sensors of the one or more sensors based on the position of the light mobility vehicle and positioning of the one or more sensors on the light mobility vehicle; receive first relevant safety-related data from the one or more relevant sensors; and transmit the first relevant safety-related data to one or more other light mobility vehicles in the group.

Abstract: The invention generally relates to VHH domains that specifically bind a severe acute respiratory syndrome coronavirus spike protein receptor binding domain, corresponding expression vectors and host cells, and methods of treatment using such VHH domains.

Abstract: A railcar coupler assembly allowing rotation of a coupler between a stored position within the railcar and an extended position for engagement with the coupler of an adjacent railcar. The coupler can be locked into either the stored or extended position with a locking pin.

Abstract: Devices and methods of altering protein concentrations in cerebrospinal fluid and/or brain interstitial fluid are disclosed. Devices include a support having at least one protease attached to the support. The device may further include a housing. Devices may be implantable for use in an in vivo active flow system or for use in an in vivo passive system. Devices may also be used in an ex vivo active flow system. Devices may also be used in a passive system to treat cerebrospinal fluid and/or brain interstitial fluid that is withdrawn, or in a passive system that is implanted surgically. Methods include contacting cerebrospinal fluid and/or brain interstitial fluid with a support including at least one protease attached to the support. Proteins contained in the cerebrospinal fluid and/or brain interstitial fluid are cleaved by the protease resulting in the reduction of protein in cerebrospinal fluid and/or brain interstitial fluid.

Abstract: A railcar coupler assembly allowing rotation of a coupler between a stored position within the railcar and an extended position for engagement with the coupler of an adjacent railcar. The coupler can be locked into either the stored or extended position with a locking pin. A corresponding rotatable brake pipe is also disclosed.

Abstract: A retention treatment basin system and method 10 that handles an influent of combined wastewater and sewer overflows. The influent includes floatable 12 and settlable solids 14. The basin includes a ceiling 16. The retention treatment basin has one or more influent channels 20 that duct the influent into the basin. A weir assembly 22 extends upwardly from the floor, over which the influent flows. A cell 24 receives the influent passing over the weir. At least some of the settlable solids are retained in the cell. A baffle 26 traps at least some of the floatable solids in the cell. Part of the influent passes under the baffle. One or more up-flow screen systems 28 with bars having a triangular cross-section extend from the baffle that are pervious to fluids for receiving the influent and arresting movement of floatable solids therethrough. The screen system creates a floatable-solids depleted effluent.

Abstract: Orally nonabsorbed or poorly absorbed drugs may be converted to orally absorbed prodrug derivatives by derivatization of free functional groups selected from amino, hydroxyl, mercapto, phosphate and/or carboxyl with groups sensitive to mild basic conditions such as 9-fluorenylmethoxycarbonyl (Fmoc), 2-sulfo-9-fluorenylmethoxycarbonyl (Fms), and fluorenylmethyl (Fm).

Abstract: There is a dough composition. The dough composition has flour, shortening, water, and a leavening system. The leavening system has a leavening base and leavening acid. The leavening acid is a combination selected from the group consisting of 1) sodium aluminum phosphate and dicalcium phosphate dihydrate; 2) sodium aluminum phosphate and sodium acid pyrophosphate; 3) sodium acid pyrophosphate and dicalcium phosphate dihydrate; 4) sodium aluminum phosphate, sodium acid pyrophosphate, and dicalcium phosphate dihydrate; 5) sodium aluminum sulfate and dicalcium phosphate dihydrate; and 6) sodium aluminum sulfate and sodium acid pyrophosphate. The sodium acid pyrophosphate exhibits an evolved percentage of carbon dioxide of about 30 or less at room temperature prior to baking. The slower reacting of the leavening acids in the combination is at least 15 wt % of the total weight of the acid combination. There are also methods for making tortillas.
