Abstract: A storage tank for receiving condensate from the evaporator of a dehumidifier includes a switch which signals when the tank is filled. The tank includes a cover upon which the condensate impacts after falling from the evaporator. The condensate flows to a drain passage of the cover to enter the storage tank. A spherical float is floating freely on the stored condensate. The underside of the cover forms an upwardly inclined guide surface which guides the float toward a switch as the level of condensate rises, whereupon the float actuates the switch.

Hollow eductor tubes affixed to the impeller drive shaft are used to flow gas from an overhead gas space to the liquid in the vicinity of the assembly. The positioning and size of the eductor tubes are such as to maximize the desired gas-liquid mixing and reaction rate.

Abstract: The efficiency of multiple downcomer type fractionation trays is increased by increasing the length of the liquid flow path and providing Lewis Case II point to plate efficiency enhancement. Baffles (7) extending axially along the vertical axis of a fractionation column divide the intertray volumes of the column into defined vapor passageways. A pair of inclined liquid deflecting baffles (3) over each downcomer (10) connects the outlets and inlets of vertically adjacent downcomers and provides a crisscrossing liquid flow path. Beds (14) of vapor-liquid contacting material increase tray efficiency.

Abstract: In a process for contacting gas and liquid, gas and liquid are simultaneously passed through a layer of irregularly shaped pieces of foamed plastic material having diameters in a range between 1 mm and 50 mm. Since the gas and the liquid are passed through a contact region filled with particles of foamed plastic material, persistence of fine bubbles is increased due to the generation of flow turbulence preferably combined with high pressure. Further, the foamed plastic particles have a low specific weight and is highly durable, it can be used for an extended period of time without losing its processing capability.

Abstract: A compact special effects fogger has a small case with a handle on top for ease in transportation. A compressor box is positioned in the case against the base, and against one side and one end of the case. A fogger head box extends across the case on top of the compressor box. The two boxes form within the case a fan chamber at one end, a compressor cooling duct along one side, and an air entrainment duct along the top. A motor drives a compressor within the compressor box. A shaft from the motor extends into the fan chamber. A squirrel cage fan driven by the shaft draws air in through a round opening in the first end of the case and increases pressure in the fan chamber, causing air to flow through the ducts. The fogger head box has an oil sump and an oil intake is mounted in the sump. Oil tubes lead to a nozzle assembly within the fogger head. Compressed air flows through an air cooler in the compressor box and through a water trap in the fan chamber and into the nozzle assembly.
