  • Patent number: 9295934
    Abstract: Devices for monitoring the end of service life of a filter cartridge include a demand substance, a sensing element with a detection point located within or adjacent to the demand substance, a reader for the sensing element, and a fluid delivery device. The detection point of the sensing element is correlated to the service life of a filter cartridge. The correlation is effected by correlation of the residence time of the monitoring device to the residence time of a filter cartridge. The residence time of the monitoring device is correlated to the residence time of the filter cartridge by control of the fluid delivery parameters of the fluid delivery device. The fluid delivery parameters include the flow rate, the demand substance mass, the receptacle cross sectional area, the receptacle volume, the receptacle length, and the demand substance packing density of the monitoring device.

  • Patent number: 9291484
    Abstract: Methods of correlating a monitoring device to the service life of a filter cartridge include providing a monitoring device, and calibrating the monitoring device to correspond to the service life of a filter cartridge. The monitoring device comprises a demand substance within a receptacle, a sensing element with a detection point, a reader for the sensing element, and a fluid delivery device. Calibration includes determining the ratio of the residence time of the monitoring device to the residence time of the filter cartridge, and utilizing the ratio to correlate the response of the sensor within the monitoring device to the service life of the filter cartridge. The response of the sensor is correlated to the service life of the filter cartridge by control of the fluid delivery parameters of the fluid delivery device.

  • Patent number: 8979985
    Abstract: A conformal filter is disclosed having a plurality of sorbent beds oriented perpendicular to an inner side surface of the filter which conforms to an adjacent surface, such as a wearer's face when attached to a respirator. The inner side of the filter may approximate the curved shape of an interfacing surface. Because the sorbent beds are oriented perpendicular to the inner side surface, a conformal configuration can be achieved without bending the sorbent beds and while keeping constant bed residence time throughout the entire cross-sectional area of the air flow, thus enforcing even air distribution. Reduced bed depth is also achieved through this configuration which consequently reduces the overall pressure drop through the filter. Other embodiments are described and claimed.

  • Patent number: 8956446
    Abstract: A separable sorption apparatus has a sorption device and a heating device. The sorption device is filled with multiple sorbent granules. The heating device is detachably mounted on the sorption device and has a heater. The sorption device is put in a room that needs dehumidifying or deodorizing. When the sorbent granules have become saturated, the heater of the heating device is mounted into the sorption device to dehumidify or deodorize the sorption device to allow the sorption device to be reused. Since the heating device is detachable, the heating device does not occupy internal space of the sorption device. Thus, the sorption device has ample internal space for receiving the sorbent granules. Consequently, the sorption device has improved sorption effect.

    Abstract: A breather including desiccant for humidity control includes an electronic end of life detection system. A temperature sensor and humidity sensor provide a temperature and humidity of the desiccant to a controller. The controller determines the relative humidity of the desiccant. The controller determines that the desiccant, and thus breather, has reached its end of life (i.e., end of useful life) when the relative humidity reaches a predetermined relative humidity (e.g., 40%). Optionally, a pressure sensor provides a pressure of the reservoir to the controller. The controller determines a fault condition or end of life condition of the breather when the pressure exceeds a predetermined pressure.

  • Patent number: 7762255
    Abstract: An improved carbon dioxide absorber for use in a closed circuit patient breathing system has a canister insertable in the breathing circuit for receiving recirculating breathing gases. The canister contains a pelletized CO2 absorbent material that removes the CO2 from the breathing gases passing through the absorber. A quantity of the CO2 absorbent material is treated with a chemical indicator such that the chemical indicator makes a color change indicative of the state of the absorptive capacity of the absorbent material. A separate quantity of the CO2 absorbent material is treated with a second chemical indicator. The second chemical indicator changes color to indicate the degree of dryness of the CO2 absorbent material. The second chemical indicator may comprise cobalt chloride and serves to indicate the potential for excessive heat generation and toxic gas generation conditions within the CO2 absorbent canister.

  • Patent number: 7744684
    Abstract: The present invention relates to a high capacity gas filter system. The metal filter of the system includes a visible indicator which indicates when the filter is spent. The indicator is preferably a non-reactive glass tube with indicator material therein. The glass tube can be protected to maintain gas flow integrity in case the glass tube breaks. The filter is attachable to or removable from its connecting base using a cooperating threaded knob and threaded bolt such that the filter is pulled tightly onto the base and forced off of the base depending on how the knob is rotated.

  • Patent number: 7713336
    Abstract: A removable disposable air dryer cartridge is provided for a small enterprise water ozonation system. The cartridge includes an air inlet to receive atmospheric air, a desiccant material to remove moisture, and a dry air outlet for interfacing with the ozonation system to provide dry air to an ozone generator. This facilitates better ozonation of water in the system, since dry air reacts better in an ozone generator, achieving higher concentrations of ozone gas, thus resulting in a better “kill rate” when ozonated water is applied to bacteria. The air dryer can be provided as a chamber of a combined air dryer and water filter cartridge, the other chamber being a water filter chamber having a water filter for extracting large particles of material from the water stream in order to prevent damage to the system.

  • Patent number: 7537648
    Abstract: A mechanical device is used to estimate a service life of an air filter exposed to a certain chemical at various concentrations, flow rates, and relative humidity conditions. The device includes two members, one of which has at least one window, connected so that their surfaces are movable relative to one another. One member has numerical values for chemical concentrations and service life estimates printed on it. The member having windows has at least one mark printed on it by which it can be oriented relative to the chemical concentration scale on the other member. When the two members are aligned relative to a chemical concentration of interest, the corresponding service life estimate is displayed in an appropriate window.
