Abstract: Se describen los montajes limpiadores de aire y los componentes para los mismos. Un cartucho de filtro primero o principal, ejemplar, es descrito, el cual incluye un paquete de medios que comprende tiras de material acanalado aseguradas a las láminas frontales, orientadas en una pila. El paquete de medios define las caras de flujo de entrada y salida opuestas, con los canalones que se extienden en una dirección entre éstos. El paquete de medios es asegurado no removiblemente dentro de un alojamiento de cartucho de filtro, en una posición entre las secciones opuestas de una bóveda, típicamente aseguradas a éste con un adhesivo. La bóveda también define un extremo cerrado, espaciado de, pero en traslape con, la cara extrema de salida del paquete de medios. El extremo cerrado es típicamente curvado y la bóveda proporciona típicamente ya sea una forma de d/b o una forma de u. El filtro incluye un miembro extremo, con un arreglo de abertura de flujo de salida en éste, permitiendo el flujo de salida desde el cartucho de filtro en una dirección general ortogonal al flujo de aire a través del paquete de medios. El montaje limpiador de aire incluye un alojamiento que tiene características para la recepción de, y el acoplamiento por, el cartucho de filtro. Se proporciona un cartucho de filtro secundario opcional, montable sobre el alojamiento en una dirección que se proyecta hacia un volumen de aire limpio en el cartucho de filtro principal.

Abstract: An air cleaner arrangement useful for cleaning air in ablative thermal imaging processes includes a housing and a removable and replaceable element assembly. The housing has an interior, an inlet conduit, and an outlet conduit. The element assembly includes first and second filter elements axially aligned and secured together in a stack configuration. The first filter element has a media pack for filtering particulate material. The second filter element has a media pack for filtering noxious gases, such as formaldehyde. In operation, a blower assembly directs airflow through the inlet conduit, into the first element interior, through the first element media pack, through the second element media pack, into the second element interior, and out through the housing outlet conduit. Methods for filtering and changing out of the element assembly are also described herein.

Abstract: Disclosed are methods for purifying polynucleotides from a feed solution using oligonucleotide affinity columns at flowrates between 0.5 CV/min to 1000 CV/min. The methods can include several steps including loading a mixture containing the target polynucleotide onto a chromatography media, e.g., a column, that carries a macroporous support with an oligonucleotide affinity ligand bonded to a surface. The affinity ligand can hybridize the targeted polynucleotide and allow for separation and purification of the target.

Abstract: A system and method of operating an air cleaner assembly including a selective scavenging apparatus that may be configured to actuate in response to a pulse cleaning operation. The air cleaner assembly may include an air cleaner housing, filter media positioned within an interior space of the air cleaner housing, a pulse cleaning apparatus extending into the interior space, and the selective scavenging apparatus in fluid communication with an egress aperture of the air cleaner housing. The selective scavenging apparatus may be configured to move fluid and sediment out of the air cleaner housing during a scavenging time period and the pulse cleaning apparatus may be configured to direct a pulse of gas into the clean air space during a cleaning operation. The scavenging time period may start based on the beginning of the cleaning operation and may end based on the completion of the cleaning operation.

Abstract: The current technology relates to substrate treatments, treated substrates, and filters. Treated substrates can have a treated surface that defines a pattern and/or gradient among untreated surface areas. A treated surface area can have a higher roll off angle for a 50 μL water droplet when the surface is immersed in toluene that the untreated surface areas. Substrates can be treated by, for example, exposing a substrate surface and/or fibers to ultraviolet (UV) radiation. UV radiation can be applied to surfaces via a mask, lens, waveguide, reflector, as examples. UV radiation can be applied to surfaces at varying intensities, which can create a treatment gradient.
