A separator element for obtaining molecular and/or particulate separation by tangential flow of a fluid medium for treatment into a filtrate and a retentate, the element comprising a structure (2) of at least two porous rigid columns (3) made of the same material, positioned side by side to define outside their outside walls a volume (4) for recovering the filtrate, each column (3) presenting internally at least one open structure (5) for passing a flow of the fluid medium, opening out in one of the ends of the porous column for inlet of the fluid medium for treatment and in the other end for outlet of the retentate. The element is a single-piece rigid structure (2) made as a single piece that is uniform and continuous throughout, without any bonds or exogenous additions.

An extruder arrangement and a method of feeding feed material into an extruder. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. 1.72(b). As stated in 37 C.F.R. 1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading Abstract of the Disclosure. The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

A filter element for the filtration of fluids can be manufactured from powdered metal using a laser manufacturing process. The powdered metal is deposited in a layer on fabrication platform and a laser beam is directed toward the layer of material so that the powdered metal granules fuse together to form a first component of the filter element. Successive layers of powdered metal can be deposited over the first component and also fused with the laser beam to form additional components. During the manufacturing process, the power or scan rate of the laser beam many be changed so that the formed layers of the filter element may have different porosity characteristics, for example, with certain portions being fluid permeable and other portions being fluid impermeable.

A filtration article having a honeycomb filter body that includes a plurality of intersecting porous walls including surfaces that define a plurality of channels extending in a longitudinal direction from an inlet end to an outlet end. The plurality of channels includes inlet channels that are open at the inlet end and sealed at locations longitudinally spaced away from the inlet end, and outlet channels that are open at the outlet end and sealed at locations longitudinally spaced away from the outlet end. Inorganic deposits are disposed on, or in, or both on and in, at least some of the walls. The inorganic deposits are bound to each other, to the walls, or to both, by a silicon-containing precursor binder.

A filter for a chromatography system includes a filter body having an exterior wall, a cavity, an interior wall surrounding the cavity and a channel extending between the exterior and interior walls. The channel passes a flow of a liquid from the cavity. The filter body is formed of a sintered metal oxide material and has a pore size that is less than a particle size to be filtered liquid. In some embodiments the filter body is formed of zirconium oxide or aluminum oxide. The filters reduce or eliminate the types of reactions that occur between conventional filter bodies and chromatographic solvents and samples. The filters can be used at different locations in a chromatography system to remove particles that may be present in sources of chromatographic solvents or introduced into the chromatographic system flow by chromatographic components, such as pumps, valves and other chromatographic system components.

The present disclosure provides an apparatus for a chlorination method to recycle metal elements in lithium batteries.

A filter system for filtering a fluid is provided with a filter housing and a filter element arranged in the filter housing. The filter element has a glass fiber filter medium. A sintered body is arranged fluidically downstream of the glass fiber filter medium for retaining constituents of the glass fiber filter medium entrained in a fluid to be filtered. A pore size of the sintered body is greater than a cross-section of the constituents of the glass fiber filter medium.

An apparatus for containing thermal events of at least one energy storage device is disclosed. The apparatus may comprise a containment enclosure including a venting chamber having a pathway. The pathway may include an inlet portion and an outlet portion and the pathway may be configured to enable emissions discharged from the at least one energy storage device to be directed from the inlet portion to the outlet portion. The outlet portion of the pathway may include an outlet aperture. A filter may be configured to filter the emissions passing through the outlet aperture of the pathway and a valve may be configured to open at a predetermined threshold pressure level to release at least a portion of the emissions into the atmosphere.

The present invention provides a method for recycling lithium batteries, including the following steps: Step 1, pretreating the lithium batteries, so as to obtain a mixture, the mixture includes positive electrodes of batteries, negative electrodes of batteries, and electrolyte; Step 2, performing oxygen-free pyrolysis on the mixture, at a pyrolysis temperature of 400-600 C.; Step 3, using a gas-solid filtration device to separate gas products from the pyrolysis, wherein anti-corrosion material(s) is (are) used to form filter element of the gas-solid filtration device; Step 4, taking out solid products from the pyrolysis, so as to recycle metal elements; the metal elements include but are not limited to one or more selected from the following: lithium, aluminum, copper, iron, nickel, cobalt, manganese.
