Abstract: An attachment for a fuel carburetor possesses a fuel inlet, a needle-and-seat valve disposed in the inlet, and a float attached to the needle-and-seat valve. In one embodiment, the attachment is placed between and is in fluid communication with both the float bowl and the metering block of a typical carburetor. Fuel is pumped into the float bowl and the attachment in parallel from the fuel pump. The float in the attachment rises and falls according to the level of fuel in the interior of the attachment and float bowl, and thus regulates the position of the needle-and-seat valve, which in turn regulates how much fuel is pumped into the attachment and float bowl. The attachment is also provided with a device for injecting a spurt of fuel directly into the metering block to avoid lean fuel conditions when the throttle is initially opened. In an alternative arrangement, the float bowl and attachment are made as one integral unit.

Abstract: The humidification device includes a tube formed of gas permeable material connected to a water source by a tube formed of material that is substantially impermeable to water. The gas permeable tube permits water to evaporate through the tube wall and is thus an evaporation tube. The evaporation tube is disposed in a chamber that is to be humidified. As water evaporates from the evaporation tube, the humidity in the chamber builds up to a maximum level. At the maximum humidity level evaporation of water from the evaporation tube ceases. When the humidity level in the chamber drops below the maximum level, evaporation of water from the evaporation tube resumes to restore the humidity in the chamber to its maximum level. Water flow from the water source replaces evaporated water from the evaporation tube. The humidification device is thus self-regulating and does not require any water flow regulating devices. One or more water flow tubes can be connected to the evaporation tube from a water source.

Abstract: The invention is directed to an apparatus for providing absorption of two fluid phases with one another. One of the phases made be a gaseous phase, while the other phase may be a liquid phase.

Abstract: The vehicular humidified cool wind system includes a blower, atomizing means, a water tank and an air passage which are integrated, and is mounted on the ceiling above the driver to blow out a humidified wind downward. The air passage is divided into a humidified wind passage to be fed with atomized water and an ordinary wind to be fed with no atomized water. The air outlet has a double duct structure, an internal cylinder and external cylinder, in which the humidified wind having passed through the humidified wind passage is blown out of an internal cylinder whereas the ordinary wind having passed through the ordinary wind passage is blown out of an external cylinder around the internal cylinder. The humidified wind is prevented from diffusing while being surrounded by the ordinary wind, so that it efficiently reaches the driver to give him a cool feeling.

Abstract: A gas injection apparatus for injecting a gas into a liquid comprising a baffle plate, a re-circulation chamber, and a discharge nozzle. The discharge nozzle is oriented normally to the baffle plate so that a liquid stream composed of the liquid is directed against the baffle plate and produces an oppositely directed flow towards the outer peripheral edge of the baffle plate. The oppositely directed flow has a sheet-like turbulent flow regime located adjacent to the plate and a circulating flow regime located above the turbulent flow regime and bounded by a re-circulation chamber. The gas is mixed into the liquid so that smaller bubbles are entrained in the turbulent flow regime and are discharged with the liquid flowing in the turbulent flow regime from the outer peripheral edge of the baffle plate. Larger bubbles flow into the circulating flow regime to break up into smaller bubbles which are entrained in the turbulent flow regime swept out of the apparatus.

Abstract: A liquid-vapor contact column comprising an outer tubular shell and a plurality trays supported within the tubular shell to intimately contact an ascending vapor phase with the descending liquid phase. An alignment of the active portions of the trays can produce a counterflow pattern in the vapor phase, opposite to the direction of flow of the liquid phase. This results in an increased hydraulic gradient taken from the outlet to the inlet of the tray. In order to inhibit the ascending vapor phase from flowing in the counterflow direction the active portions of the trays are staggered.
