Abstract: A 3D printing apparatus to dehumidify and recycle a gas from a 3D printer is disclosed herein. The apparatus comprises: a gas inlet to receive a gas flow from a 3D printer, the gas flow comprising gas with evaporated solvents to be cleaned; a heat exchanger to dehumidify the gas flow from the evaporated solvents, the heat exchanger to cool the gas flow by heat transfer to a cold liquid stream from a chiller to saturate and condensate the solvents from the gas flow; a gas outlet to output the dehumidified gas flow back to the 3D printer; and a controller. The controller is to receive a humidity and temperature measurements from a sensor located downstream from the heat exchanger; compare the humidity and temperature measurements with a target humidity and a target temperature respectively; and control a chiller valve from the chiller based on the comparison to adjust the temperature of the gas flow to set an absolute humidity of the gas flow to a predeterminable value.

Abstract: A printhead servicing system comprises a humidified air stream generator (10) to generate a humidified air stream; a humidified air stream channeling module (20) to channel the generated humidified air stream to a humidified air stream ejection module (30) to eject the humidified air stream towards a printhead nozzle plate (52a) of a printer (50); and a wiping module (40) to wipe a printhead nozzle plate (52a) of the printer.

Abstract: A personal mister system includes a manually operated mist delivery assembly having a trigger actuated spray bottle and water delivery tubing configured to deliver water from the spray bottle to a series of mister nozzles positioned along a portion of the water delivery tubing provided in a circular configuration. The portion of the water delivery tubing provided in a circular configuration is removably attachable to a user selected hat. A bottle carrier is further provided for carrying the spray bottle in a handsfree manner. The device supplies mist to a user to lower the body temperature of the user and provide immediate cooling effects.

Abstract: Provided are personal care compositions comprising a first surfactant comprising sodium lauryl sulfate and a second surfactant having a structure represented by wherein each a has a value of about 1 to about 110, b has a value of about 16 to about 70, and at least one R group is SO3, and the other R group is SO3 or hydrogen. Also provided are methods of producing personal care compositions and methods of ameliorating skin or mucosal membrane irritation due to sodium lauryl sulfate.

Abstract: Provided herein are cleaning compositions that are particle-free. The compositions comprises a solution containing one or more alkyl polyglucosides and one or more 2-propylheptanol alkoxylates, wherein the one or more 2-propylheptanol alkoxylates have a relatively low hydrophilic-lipophilic balance value. Also provided are methods of making and using same.

Abstract: Personal care products exhibiting superior conditioning and/or color fastness can be obtained by use of mixtures of certain phosphate esters and polyquats.
