Abstract: Slurry compositions, tape casting binder systems and fabrication methods for the fabrication of lithium-garnet electrolyte scaffolds for use in solid state batteries and other devices are provided. Slurry compositions may be optimized mixtures of LLZO powder, a dispersant, a lithium salt, a wetting agent a binder, a plasticizer and at least one solvent. The optimized ceramic slurry compositions may include MgO as a sintering additive to improve density and ionic conductivity of the doped-LLZO sheets and produce a fine-grained microstructure. Sintering protocols for cast slurries of commercially available doped LLZO powders eliminate the requirement of mother-powder coverings or externally applied pressure. An environmentally friendly water-based system using methylcellulose as a binder is also provided producing green tape and final properties comparable to those obtained with organic solvent-based systems.

Abstract: A refrigerant heat exchanger including a first group of heat exchange tubes on a first side of a core defining a first zone. A second group of heat exchange tubes on a second side of the core define a second zone. An inlet tank is at the inlet end of the core. An inlet port of the inlet tank is opposite to, or generally opposite to, an interface between the first zone and the second zone. A first outlet tank is at the outlet end of the core opposite to the first zone. A first outlet port of the first outlet tank is at an outer end of the first outlet tank. A second outlet tank is at the outlet end of the core opposite to the second zone. A second outlet port of the second outlet tank is at an outer end of the second outlet tank.

Abstract: Roll-dispensed stock containers are provided. The roll-dispensed stock containers can include a recessed cutting track positioned along a length of a support wall of the container. The support wall can also include one or more apertures positioned adjacent to the recessed cutting track configured to receive a base of a slidable cutter movable along an elongated slot in a lid of the container. The base of the slidable cutter is captured by the recessed cutting track during a cutting operation to secure the lid in a closed position and to apply constant pressure against roll-dispensed stock as it is cut. Roll-dispensed stock containers of the present disclosure can also include a coating on one or more surfaces thereof. The coating can be formed from a material selected to reduce surface friction, increase rigidity, disperse forces associated with a cutter, and/or otherwise enhance characteristics of the container.

Abstract: Some embodiments facilitate creation of an industrial asset item via an additive manufacturing process wherein motion is provided between a build plate and a print arm. A correction engine may receive, from an industrial asset item definition data store containing at least one electronic record defining the industrial asset item, the data defining the industrial asset item. A correction engine computer processor may then correct the motion provided between the build plate and the print arm such that the motion deviates from a path indicated by the data defining the industrial asset item. The three-dimension printer may be a rotary printer such that the build plate rotates about a vertical axis and moves along the vertical axis during printing. In these cases, a pre-compensation algorithm may be applied to correct the motion provided between the build plate and the print arm before transmitting data to the three-dimensional additive manufacturing printer.
