Abstract: A raising assembly for use with a gangway connected for rotation between a raised stowed position and a lowered deployed position. The raising assembly comprises at least one fluid actuated cylinder connected to the gangway. A raising actuator is operative to cause operation of the cylinder in a manner that rotates the gangway toward the stowed position while the raising actuator is continuously activated by an operator. A lowering actuator is operative to cause operation of the cylinder in a manner that rotates the gangway toward the deployed position due to gravitational forces while the lowering actuator is continuously activated by the operator. The raising assembly is configured to maintain the gangway at a current position between the stowed position and the deployed position if the operator does one of ceasing to activate the raising actuator while raising the gangway or ceasing to activate the lowering actuator while lowering the gangway.

Abstract: Novel compounds, compositions, and methods of using and preparing the same, which may be useful for treating alpha-1 antitrypsin deficiency (AATD).

Abstract: An elevating cage apparatus includes a support structure and a carriage that is operable to move vertically with respect to the support structure. The carriage is configured to be alternatively raised and lowered via a first driver and a second driver. The first driver may comprise a powered (electric, hydraulic, or pneumatic) motor, and the second driver may comprise a manual actuation mechanism including a hand crank. Both input drivers may be operable to move the carriage through a dual input worm drive gear box.

Abstract: A gangway comprises a fixed platform and a support structure connected to the fixed platform in a manner that allows the support structure to rotate with respect to the fixed platform between a raised stowed position and a lowered deployed position. A self-raising assembly is operative to rotate the support structure from the deployed position to the stowed position. The self-raising assembly includes at least one fluid actuated cylinder connected between the fixed platform and a distal end of the support structure. A raising actuator is usable by an operator to cause operation of the cylinder in a manner that rotates the support structure toward the stowed position.

Abstract: A compact transportable water treatment system for treating water in a reservoir includes a batching unit having a chemical hopper for holding dissolvable chemicals and having a fluid inlet for delivery of fluid into the hopper for dissolving the chemicals to create a chemical solution and a fluid outlet in a lower portion of the chemical hopper for outflow of chemical solution. The batching unit further includes a fluid delivery system configured to deliver the fluid to the chemical hopper through the fluid inlet and a batching tank that receives and holds the chemical solution passing from the fluid outlet. A dosing unit comprising at least one dosing pump is configured to pump the chemical solution from the batching tank to a dosing line. A control unit controls operation of the dosing unit responsive to a chemical concentration of the water in the reservoir.

Abstract: A multi-packet-switch system having a standard primary switch interconnect to handle inter-switch packet traffic, separate buffer areas for each primary interconnect and the device ports, the ability to identify specific packet streams by an identifier in each packet, and the ability to specifically manage static routing of packets based on the packet stream identifier. Creating secondary switch interconnects between device ports, and routing identified packet streams to these secondary switch interconnects. The secondary switch interconnects can be dedicated to identified packet streams, thus eliminating primary interconnect buffer contention with other packet streams.
