摘要:
A filter medium for use in filtering a mobile fluid made from at least a bicomponent fiber. Other fibers, particles, or other materials can also be entrained in the filter medium. The filter medium has a substantial thickness compared to filters of the prior art. The fiber length and diameter dimensions are selected to obtain desired filter characteristics including thickness, basis weight, pore size, filtration efficiency, pressure drop, burst strength, and manufacturing efficiency. Further, a multilayer filter medium can be provided with ease. Each layer can have a different composition, pore size, basis weight, and so forth, thus providing the ability to build multiple functionality into the filter media of the invention.

A configuration for treating exhaust gases of an internal combustion engine having a predetermined displacement volume, includes an exhaust gas recirculation line. Exhaust gas flowing through the exhaust gas recirculation line interacts with a turbocharger. A screening layer is provided in the exhaust gas recirculation line upstream of the turobcharger. The screening layer is larger than an average cross section of the exhaust gas recirculation line. A motor vehicle having at least one such configuration is also provided.

Provided by the present invention is a wet-layed, nonwoven sheet which is comprised of metal fiber and metal powder. Generally, the amount of metal fiber comprises from 20 to 95% by weight and the amount of metal comprises from 5 to 80% by weight of the sheet. Such a wet-layed nonwoven sheet is economically preferable to a sheet comprised totally of metal fiber, since the metal powder is much less expensive. Among other factors, the present invention is based upon the recognition that by using various process techniques, the combination of metal fiber and metal powder can be wet-layed to obtain a structure of sufficient strength for subsequent handling and sintering.

An electrolytic process employing a diaphragm of a size of at least 1 cm in length in at least two directions, the diaphragm comprising a diaphragm base composed of fibers of fibrous structure containing inorganic fibers and a binder containing a fluorine-containing resin, the fluorine-containing resin being present in an amount of 0.5 - 60% by weight based on the weight of the diaphragm.
摘要:
A method of manufacturing an inside-to-outside flow filter tube and the filter tube so manufactured which comprises: providing a porous tube comprising a wet mat of randomly disposed glass fibers; positioning an external reinforcing sleeve material concentrically about the porous tube; applying an outward force to the porous tube to expand the external diameter of the porous tube into intimate contact with the sleeve material; and drying the tube and bonding the fibers of the tube into an integrally supported filter tube.
摘要:
A structure of a metal fiber constituting a filter is set to a structure in which a cross-sectional shape of the metal fiber is a curved or bent shape and an outer member and an inner member having a linear expansion coefficient greater than that of the outer member are bonded to each other. Accordingly, the metal fiber is deformed to warp to the outer member side in the length direction thereof when the temperature of the metal fiber increases. When a amount of deformation per unit temperature of the metal fiber is defined as a deformation rate, a amount of change of the deformation rate per unit time changes at a predetermined deformation temperature with the increase in temperature. The deformation temperature is set to a temperature higher than a target temperature of a filter regenerating process.
