Abstract: A packing material unit for use in liquid-gas contact apparatuses, which comprises outer and inner rings, and a plurality of pairs of arched filaments positioned side by side such that their curved outer surfaces are oriented alternately to opposite sides of the plane involving the outer and inner rings to form a plurality of circular or elliptic loops arranged about an imaginary circle which is concentric with the outer and inner rings. A connecting member is bridged between intermediate portions of each pair of the filament. A plural number of reinforcing members extend between apex portions of oppositely arched filaments of adjacent filament pairs. The connecting members and reinforcing members serve both to prevent the interlocking of adjacent packing material units and to improve mechanical strength of the unit.

Abstract: A system of apparatus is especially adapted to react gaseous contaminates of natural gas streams with a slurry of reactant particles and incorporates a contactor tower with a bottom gas inlet having a screen at its dynamic liquid level to confine downwardly a fill of packer-spacer material. Gas entering through the bottom inlet of the tower is divided by the packer-spacer material in tortuous flow paths maintained by the confining screen.In advance of the contactor tower, after an inlet scrubber, is a heater which elevates the temperature of the gas before it enters the contactor tower. This avoids formation of clogging hydrates and liquefication of the gas. Using an outlet scrubber assures against entrance of droplets of any liquid into the pipeline.

Abstract: A lock for vehicle closures or flaps, especially doors, trunk lids and fuel tank caps or lids, wherein the cylinder of the lock includes a drain opening in the lower part thereof which communicates with the interior of the cylinder and through which moisture, especially water, can be drained from the interior of the lock. A drain line formed as a moisture absorbing wick provided with an electric heating element powered by the vehicle electric system is connected to the drain opening with the line being guided from the cylinder through an element, such as a door handle, containing the cylinder, to the interior of the closure.

Abstract: A humidifier for air or gas flow to the lungs heats the flow and saturates it with water vapor. Heated water injected into a humidifying passage flows down multiple paths in the gas stream. Heating of the water is shown on a localized basis at sterilizing temperature while over-all temperature is kept lower using a heater combined with the pump of the injection line. All surfaces of the humidifier are shown exposed to the water; the gas outlet connection is shown communicating with a space between the water paths and the reservoir, and directed toward the reservoir; and the humidifying passage is shown as a tubular column holding a mass of tangled inert filaments.

Abstract: A humidifer for aqualung equipment comprises a source vessel housing moistening water which is or is not contained in a fibrous material member, and a water applying passage disposed to communicate the source vessel with the gas supply passage of the respirator and normally shutting off such communication, whereby when pressure in the gas supply passage is temporarily lower than that in the source vessel upon respiration of the user, such pressure difference may cause the water in the source vessel to be applied in a sprayed form from the applying passage into the gas supply passage. A further humidifier includes a water containing fibrous material member disposed directly in the gas supply passage of the respirator and kept to be in a water containing condition by supplying water through the aforementioned water applying passage.
