20090007789 | THERMAL INSULATOR - An adsorbent capable of adsorbing gas low in activity such as nitrogen is used, and a thermal insulator high in production efficiency and excellent in adiabatic performance is presented. A thermal insulator has an adsorbent, a core material, and an enveloping member. The adsorbent includes Li and solid matter of hardness of 5 or more. The gas adsorbing activity becomes very high, and for embodiment by evacuating to a certain degree of vacuum by using a vacuum pump, the remaining gas is adsorbed by the adsorbent of the invention to obtain a desired degree of vacuum, so that a thermal insulator of high production efficiency is obtained. Since the heat conductivity is decreased by adsorbing gas of low activity in the enveloping member, the adiabatic performance is enhanced. | 01-08-2009 |

20120118160 | Attrition resistant hardened zeolite materials for air filtration media - Environmental control in air handling systems that are required to provide highly effective filtration of noxious gases particularly within filter canisters that are ultrasonically welded enclosures is provided. In one embodiment, a filtration system utilizes a novel zeolite material that has been hardened to withstand ultrasonic welding conditions in order to reduce the propensity of such a material to destabilize and/or dust. Such a hardened zeolite thus enables for trapping and removal of certain undesirable gases (such as ammonia, ethylene oxide, formaldehyde, and nitrous oxide, as examples) from an enclosed environment, particularly in combination with metal-doped silica gel materials. Such a hardened zeolite is acidic in nature and not reacted with any salts or like substances and, as it remains in a hardened state upon inclusion within a welded filter device, the filter medium itself permits proper throughput with little to no dusting, thereby providing proper utilization and reliability for such a gas removal purpose. Methods of using and the application within specific filter apparatuses are also encompassed within this invention. | 05-17-2012 |
