Reinforced spin on rechargeable filter and related method of manufacture
A rechargeable spin-on filter includes a cover, a housing threadably joined with the housing, and a filter element can be replaced with another filter element relative thereto. The cover and/or housing can be plastic. The cover can include a bottom plate having inlet ports and an outlet port. The bottom plate can be reinforced with an optionally metal reinforcing plate that registers and locks relative to the bottom plate via locking elements, in the form of corresponding apertures and projections or tabs that interfit with one another. A related method is provided.

Removal System and Removal Aid for a Separating Element
A removal system is provided with a separating element for separating contaminants contained in a fluid and with a removal aid for removing the separating element from a housing. The separating element has an end disk arranged at an end face of the separating element. The end disk has a central recess. The removal aid has a grip section and at least two locking fingers. The locking fingers extend along a center axis of the removal aid away from the grip section. Each locking finger has a hook element that serves for engaging behind the end disk of the separating element radially outside of an end disk area that delimits in radial outward direction immediately the central recess. A removal aid for such a removal system is provided.
Fuel Filter Comprising a Fuel Filter Insert with a Prefilter Element and a Main Filter Element
A fuel filter has a filter housing and a fuel filter insert exchangeably arranged in the filter housing and provided with a prefilter element and a main filter element. Prefilter element and main filter element are positioned one behind the other in the filter housing in axial direction of the filter housing. A fuel discharge channel is arranged in the filter housing below the fuel filter insert. In operating position of the fuel filter insert in the filter housing, the raw sides of prefilter element and of main filter element are sealed relative to the fuel discharge channel by seal-tight contact of the fuel filter insert on the filter housing. The raw side of the main filter element, when the fuel filter insert is moved by axial movement away from the operating position, is fluidically connected with the fuel discharge channel via the raw side of the prefilter element.

Filter element integrated seal profile
An integrated seal member includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. The at least partially annular body includes a mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and an apertured connecting portion that extends radially outwardly from the mounting portion to the sealing portion.
Method and apparatuses for screening
Embodiments of the present disclosure include a screen basket apparatus includes a substantially vertical cylindrical frame and a synthetic screening surface secured to the frame. The synthetic screening surface may be configured to separate carbon or resin from a slurry of a carbon-in-leach, carbon-in-pulp, resin-in-leach, or resin-in-pulp material as fluid flows from outside to inside the screen basket apparatus such that carbon or resin is retained on an external surface of the synthetic screening surface. The cylindrical frame may be a grid frame and the synthetic screening surface may include a plurality of replaceable screen assemblies attached to the grid frame. The grid frame may include a plurality of openings and each of the plurality of openings is configured to receive a respective one of the plurality of replaceable screen assemblies. The synthetic screening surface may include injected molded thermoplastics, thermoset polyurethanes, and/or other polymeric materials.

PERIODIC RADIAL SYMMETRY FOR FILTER PLEATING
A cylindrical filter element having a central longitudinal axis and filter media including a plurality of radially extending pleats arranged in a pattern that repeats around the central longitudinal axis. Each of the pleats comprises an inner pleat tip, wherein the inner pleat tips of each pattern define an open area that extends along a height of the filter element, and wherein each pattern of pleats comprises a first series of intermediate pleats that descends in length from a major pleat to a minor pleat and a second series of intermediate pleats that ascends in length from the minor pleat to a major pleat of an adjacent pattern of pleats.
