摘要: An electrolytic device adapted for mounting on the interior wall of a container housing sorbent chemicals for detection and display of moisture content. A sandwich or tab-type probe includes superhydroscopic MgClO.sub.4 or CaSO.sub.4 particles which resist electrical current flow when dry and have a higher affinity for moisture than the sorbent chemicals in cartridges or filters. Moisture intrusion is drawn to the anhydrous MgClO.sub.4 or CaSO.sub.4 particles changing their ohmic resistance and thereby enabling visual and nondestructive detection of the moisture intrusion into the container or cartridge. The probe is spaced away from the sorbent chemicals avoiding the transfer of mechanical stresses and any additional pressure drop through the sorbents, thereby permitting the device to be used in combination with a wide range of sealed containers and air filters.

摘要: A system and filter apparatus therefore are described for providing substantially bacteria-free, humidified oxygen to a breathing mask or breathing tube. The filter apparatus is hydrophobic and is inserted either at or adjacent the outlet of a humidifier, in the flow line between the outlet of the humidifier and the breathing mask, or at or adjacent the breathing mask, and can be easily replaced when contaminated after a period of use.

摘要: A colorimetric indicator for use in indicating the impending exhaustion of a vinyl organo filtering device. The colorimetric indicator material consists of activated alumina impregnated with between 0.5 to 5.0% by weight potassium permanganate and is positioned immediately behind a window in a canister or cartridge used in filtering vinyl organo materials.
