摘要： Dry-scrubbing media compositions, methods of preparing same, and methods of use are provided. The compositions contain activated alumina and potassium carbonate. Optionally, activated carbon and other impregnates, such as sulfates of group 1A metals, are included in the compositions. The compositions exhibit improved efficiency and capacity for the removal of compounds such as chlorine or sulfur dioxide from an air-stream. The compositions are particularly useful for reducing or preventing the release of toxic gaseous compounds from the areas such as petroleum storage areas, refineries, drinking water systems, sewage treatment facilities, swimming pools, hospital morgues, animal rooms, and pulp and paper production sites.

摘要： Methods and apparatuses for mounting a filtration housing for solid filtration media. One aspect of the invention comprises a method for mounting an air circulation component to an air circulation system, wherein the air circulation component comprises a center of gravity. The method includes providing a notch associated with an air circulation component, wherein the notch comprises a contact surface; providing a guide associated with the air circulation system, wherein the guide comprises a load bearing surface; and positioning the air circulation component with respect to the air circulation system such that a portion of the contact surface is adjacent to a portion of the load bearing surface, wherein the adjacent surfaces comprise a contact angle that is substantially coplanar with a center of gravity of the air circulation component, and wherein a portion of the weight of the air circulation component transferred between the surfaces causes a sealing pressure against a portion of the air circulation system.

摘要： Procédé et appareil d'utilisation d'un cristal piézo-électrique traité afin de contrôler et de signaler la corrosion en termes reconnus comme conformes à une norme industrielle. L'invention concerne un procédé et un système de contrôle de la corrosion en atmosphère corrosive, comprenant et mettant en oeuvre les étapes consistant à exciter dans l'atmosphère un cristal revêtu d'une substance métallique attaquable par la corrosion et ayant une fréquence de vibration connue; à mesurer le changement de fréquence de vibration résultant de la corrosion de la substance attaquable par la corrosion pendant chaque intervalle d'une pluralité d'intervalles de temps, comprenant un intervalle de référence suivi d'au moins un intervalle de mesure; à générer un signal d'épaisseur représentant l'épaisseur de corrosion correspondant au changement mesuré de la fréquence pendant l'intervalle de mesure; et à convertir le signal d'épaisseur de corrosion de l'intervalle de mesure en un signal de référence représentant l'épaisseur de la corrosion accumulée pendant l'intervalle de référence. L'invention consiste également de préférence à corriger le changement de fréquence mesuré pendant chaque intervalle afin de rendre compte de toute déviation dans la température dans l'atmosphère à partir d'une température de normes préétablies. L'invention comprend également, de préférence, un capteur d'humidité servant d'impulsion afin de transmettre une alarme à l'utilisateur si l'humidité relative est supérieure à une limite préétablie, ou si l'humidité relative change pendant un intervalle de plus d'une limite préétablie. Selon l'invention, un moniteur de corrosion trouve une application dans des environnements tels que des salles de mesure et de régulation de traitement industriel, des centres de commande de moteur, des locaux électriques, des salles blanches à semiconducteur, des sites de fabrication électroniques, des centres de données commerciaux, des musées, des librairies et des salles de stockage d'archives.

摘要： A method and apparatus for using a coated piezoelectric crystal to monitor and report corrosion in terms recognized as conforming to an industry standard is disclosed. The present invention provides a method of and system for monitoring corrosion in a corrosive atmosphere, comprising and carrying out the steps of exciting in the atmosphere a crystal, coated with a corrodible metallic substance and having a known vibration frequency; measuring the change in the frequency of vibration resulting from corrosion of the corrodible substance during each of a plurality of intervals of time, including a reference interval and at least one subsequent measurement interval; generating a thickness signal representing the thickness of corrosion corresponding to the measured change in frequency during the measurement interval; and converting the corrosion thickness signal for the measurement interval to a reference signal representing the thickness of corrosion accumulated during the reference interval. The invention also preferably includes correcting the measured frequency change during each interval to account for any deviation in the temperature in the atmosphere from a preset standard temperature. The present invention also preferably includes a humidity sensor, which serves as the impetus for providing an alarm to the user if the relative humidity is above a preset limit, or if the relative humidity changes during an interval by more than a preset limit. A corrosion monitor according to the present invention finds application in such environments as industrial process measurement and control rooms, motor control centers, electrical rooms, semiconductor clean rooms, electronic fabrication sites, commercial data centers, museums, libraries, and archival storage rooms.
