Patent number: 8956446Abstract: 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.Type: GrantFiled: July 31, 2012Date of Patent: February 17, 2015Inventor: Tsang-Hung Hsu

Patent number: 7713336Abstract: 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.Type: GrantFiled: March 17, 2006Date of Patent: May 11, 2010Assignee: Tersano Inc.Inventors: Steve L. Hengsperger, Justin L. Namespetra, Christopher B. Caldwell, Richard S. Zulik

Patent number: 7553355Abstract: Novel uses and methods of use for inorganic and macroreticulate polymer bonding to metals to control moisture and oxygen in OLED, and other like devices, are provided. Materials having color change capacity are also provided for the removal of moisture from an OLED, where the material changes color upon reaching its capacity and thereby signals the user that the OLED is no longer protected from moisture damage.Type: GrantFiled: June 23, 2004Date of Patent: June 30, 2009Assignee: Matheson Tri-GasInventors: Robert Torres, Jr., Tadaharu Watanabe, Joseph V. Vininski

Patent number: 7537648Abstract: 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.Type: GrantFiled: April 26, 2006Date of Patent: May 26, 2009Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Christopher J. Karwacki, Gregory W. Peterson, Yuqing Ding

Patent number: 7442237Abstract: An end-of-service-life-indicator for a multi-agent respirator filter that is safe, reliable, and easy to read and may be configured to cover a broad range of threats, including chemical warfare agents and toxic industrial chemicals, is achieved by positioning an array of chemically reactive calorimetric indicators substantially next to a sorbent bed behind a viewing window that may be integrated into the filter housing. Each colorimetric indicator in the array may be configured to produce a color change in responsive to a different target threat or threat category and may be calibrated to display easily identifiable colors, symbols or patterns to indicate an optimum time to exchange a filter.Type: GrantFiled: September 8, 2005Date of Patent: October 28, 2008Assignee: The United States of America as Represented by the Secretary of the ArmyInventor: Paul D.
