摘要： Aspects of the disclosure generally provide a heat engine system and a method for regulating a pressure and an amount of a working fluid in a working fluid circuit during a thermodynamic cycle. A mass management system may be employed to regulate the working fluid circulating throughout the working fluid circuit. The mass management systems may have a mass control tank fluidly coupled to the working fluid circuit at one or more strategically-located tie-in points. A heat exchanger coil may be used in conjunction with the mass control tank to regulate the temperature of the fluid within the mass control tank, and thereby determine whether working fluid is either extracted from or injected into the working fluid circuit. Regulating the pressure and amount of working fluid in the working fluid circuit selectively increases or decreases the suction pressure of the pump to increase system efficiency.

摘要： A method for converting thermal energy into mechanical energy in a thermodynamic cycle includes placing a thermal energy source in thermal communication with a heat exchanger arranged in a working fluid circuit containing a working fluid (e.g., sc-CO2) and having a high pressure side and a low pressure side. The method also includes regulating an amount of working fluid within the working fluid circuit via a mass management system having a working fluid vessel, pumping the working fluid through the working fluid circuit, and expanding the working fluid to generate mechanical energy. The method further includes directing the working fluid away from the expander through the working fluid circuit, controlling a flow of the working fluid in a supercritical state from the high pressure side to the working fluid vessel, and controlling a flow of the working fluid from the working fluid vessel to the low pressure side.

A heat exchanger coil may be used in conjunction with the mass control tank to regulate the temperature of the fluid within the mass control tank, and thereby determine whether working fluid is either extracted from or injected into the working fluid circuit. Regulating the pressure and amount of working fluid in the working fluid circuit helps selectively increase or decrease the suction pressure of the pump, which can increase system efficiency.

摘要： A retractable barrier system includes an example gear assembly that can be manipulated for rapidly deploying a flexible barrier, exerting high torque for the initial tightening of the barrier, maintaining high static tension in barrier when in use, and/or rapidly retracting barrier for storage. In some examples, the gear assembly is a worm drive with a worm that can be selectively disengaged from a worm gear. Other optional features of the barrier system include selective right-hand/left-hand configurations, an electric switch that can be added to indicate whether the barrier system is in use, an intermediate coupling that joins the distal ends of two barriers for creating an extra long barrier system, and removable vehicle-mounted posts for certain loading dock applications.

摘要： A vertically moving door of a truck loading dock includes a disconnectable horizontal joint that provides the door with a barrier position, wherein an upper section of the door can be separated from a lower section to create a ventilation area between the two. The ventilation area allows fresh outside air to enter the building, while the lower section remains at its lowermost position for safety and security. More specifically, the lower section serves as a barrier that helps prevent someone or something from accidentally falling through the doorway when a truck is not present at the dock. A lightweight, resilient strap can be attached to the lower section of the door to help protect that section from an otherwise damaging impact. A lattice of straps or a mesh can be installed across the ventilation area to help secure the building against theft.
