Abstract:
An air/liquid exchanger comprising an open-cell foam 102 supporting a liquid sorbent. The exchanger may be used for removing trace gaseous components from the air.
Abstract:
The present invention is directed to methods for removing carbon dioxide from air, which comprises exposing solvent covered surfaces to air streams where the airflow is kept laminar, or close to the laminar regime. The invention also provides for an apparatus, which is a laminar scrubber, comprising solvent covered surfaces situated such that they can be exposed to air stream. In another aspect, the invention provides a method and apparatus for separating carbon dioxide (CO2) bound in a solvent. The invention is particularly useful in processing hydroxide solvents containing CO2 captured from air.
Abstract:
An automotive fluid filter comprises a plurality of pellets that are sintered together and define a plurality of pores therebetween for passage of automotive fluid through the pores so as to filter the automotive fluid when the automotive fluid is advanced therethrough. An associated method is disclosed.
Abstract:
A method of manufacturing an oil filter module comprises directing a laser beam at a surface of an end cap but not at a rim of the end cap so as to fuse at least a portion of the end cap, spacing the end cap and the filter medium apart from one another during the directing step, inserting an end of the filter medium into the laser-fused portion so as to bond the end of the filter medium and the end cap together upon re-solidification of the laser-fused portion, and preventing flow of the laser-fused portion caused by the inserting step from reaching a peripheral diameter of the end cap by use of the rim.
