Abstract: A fluid recovery system for a laundry system (e.g., of a spacecraft) can include a main line having an inlet configured to fluidly communicate with a washing volume within an agitation chamber to receive washing fluid from the agitation chamber, a vacuum source in fluid communication with the main line to provide a partial vacuum to the inlet to cause washing fluid in the washing volume to at least partially evaporate, and a condenser disposed on the main line downstream of inlet. The condenser can be configured to receive evaporated washing fluid and to condense water in the evaporated washing fluid. The system can include a separator downstream of the condenser configured to separate water and laundry effluent gas, wherein the separator includes a water recovery output configured to output water for reuse.

Abstract: A multi-waste processing system includes a processing chamber. The processing chamber includes one or more heaters and a piston, and the processing chamber is configured to evaporate liquid waste and compact solid waste input. A condenser is operably connected to the processing chamber. The condenser is configured to condense water from the evaporated liquid waste output from the processing chamber. A gas and water separator is operably connected to the condenser. The gas and water separator is configured to separate water from the evaporated liquid waste output from the processing chamber. A recirculation pathway connects the gas and water separator to the processing chamber to recirculate gas from the gas and water separator to the processing chamber. The piston is actuated to keep the one or more heaters in close proximity to the solid waste and the liquid waste in the processing chamber.

Abstract: In accordance with at least one aspect of this disclosure, a waste fluid water recovery system can include a waste fluid inlet line configured to connect to a waste fluid source, the waste fluid inlet line comprising one or more treatment components configured to treat the waste fluid, a treated waste fluid outlet line configured to connect to one or more outlets, a tank having a flexible membrane dividing an internal volume of the tank into a first portion and a second portion, a first line fluidly connected to the first portion of the tank, a second line fluidly connected to the second portion of the tank, and a switching valve connected between the first line, the second line, the waste fluid inlet line, and the treated waste fluid outlet line. The switching valve can be configured to connect the first line with the waste fluid inlet line and the second line with the treated waste fluid outlet line in a first state.

Abstract: A laundry system can include an input shaft, an output actuator, and a motion converter connected between the input shaft and the output actuator. The motion converter can be configured to convert rotational motion of the input shaft to linear motion of the output actuator. The system can include a laundry agitation arrangement connected to the output actuator to be linearly actuated by the output actuator to agitate laundry.

Abstract: Systems, methods, and apparatuses for workpiece processing with plasma, including thermal isolation of a workpiece holder assembly, are described. An apparatus includes a chamber that at least partially defines a processing space for generating plasma. The apparatus includes a base assembly that at least partially defines a lower end of the chamber and has an inner perimeter that defines an opening in the base assembly. The apparatus further includes a workpiece holder assembly positioned, at least in part, within the opening. The workpiece holder assembly includes heating element(s) and a body with an upper surface configured to receive a workpiece. A gap is defined between the inner perimeter of the base assembly and an outer perimeter of the body. The gap is configured to thermally isolate the base assembly from the body.
