Abstract: A modified two-phase refrigeration cycle compresses a working fluid, condenses the working fluid into a saturated or supercooled liquid, expands the saturated or supercooled liquid into a two-phase fluid, and evaporates the two-phase working fluid. The modified two-phase refrigeration cycle reduces irreversibilities imposed by conventional refrigeration cycles and extracts energy from the working fluid during the expansion process. For instance, a system that employs the modified two-phase refrigeration cycle includes a two-phase expander to reduce irreversibilities during an expansion process and extract energy. In some instances, the system includes a two-phase compressor to compress two-phase fluids for varying loads and environmental conditions of the system.

Abstract: A method for providing a smoothly mixed slurry to a web is provided which includes inserting calcined gypsum and water into a mixer (12), agitating the contents of the mixer (12) to form an aqueous dispersion of the calcined gysum, and passing the agitated contents from an outlet (20) of the mixer (12) into a slurry dispensing apparatus (22) including a flexible, resilient conduit (24). Additionally, the method includes the step of creating a back-pressure on the mixture in the slurry dispensing apparatus by constricting the conduit (24). The constricting of the conduit (24) is effected by a constrictor valve (28) located on the conduit (24).
