Abstract: Systems and methods for reducing the pressure of a first pressurized fluid, thereby reducing the temperature of the pressurized fluid, and utilization of the reduced-pressure and temperature fluid to cool a second fluid. Such an approach can enable a reduction in the size and weight of a hydraulic system, utilize waste energy in a system, and/or minimize electrical power requirements of a system, among other benefits.

Abstract: Brayton cycle apparatus for extracting energy from waste heat released by industrial devices are disclosed. An exemplary apparatus comprises a common structure to which the main components of a Brayton cycle are mounted in an in-use configuration to define a transportable unit for integration with an industrial device. Associated systems and methods are also disclosed.

Abstract: A turbine-generator device for use in electricity generation using heat from industrial processes, renewable energy sources and other sources. The generator may be cooled by introducing into the gap between the rotor and stator liquid that is vaporized or atomized prior to introduction, which liquid is condensed from gases exhausted from the turbine. The turbine has a universal design and so may be relatively easily modified for use in connection with generators having a rated power output in the range of 50 KW to 5 MW. Such modifications are achieved, in part, through use of a modular turbine cartridge built up of discrete rotor and stator plates sized for the desired application with turbine brush seals chosen to accommodate radial rotor movements from the supported generator. The cartridge may be installed and removed from the turbine relatively easily for maintenance or rebuilding. The rotor housing is designed to be relatively easily machined to dimensions that meet desired operating parameters.

Abstract: A container with a flexible membrane sealed to a container end may be tested for leaks as the container moves along a conveyor. The conveyor carries the container through a first region in which a negative pressure differential is established between the first region and the interior of the container. The pressure differential can be established, for example, by cooling the first region with cold air. The conveyor also carries the container from the first region to a second region, in which a positive pressure differential is established between the second region and the interior of the container. The pressure differential in the second region can be established, for example, by heating the second region with hot air. In the second region, a sensor detects a transition of the membrane of the container between convex and concave orientations and produces a signal corresponding to the occurrence of the transition.
