Abstract: A filter for filter air for an internal combustion engine and methods of operation are described herein. The air precleaner is configured to use electrostatic attraction or repulsion to move ionized particles towards an inner wall of the air precleaner, where the particles eventually exit the air precleaner through a particle exhaust. The particles are ionized using a positive charge plate and a negative charge plate. The positive charge plate creates a positive charge field, creating positive ions that ionize particles in the air with a positive charge. The negative charge plate creates a negative charge field, creating negative ions that ionize particles in the air with a negative charge. The air precleaner can also include a cyclonic section that causes the air to rotate about a central axis of the air precleaner, imparting a centripetal force on the particles. The centripetal force and the electrostatic force act together to filter the air.

Abstract: 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 top annular mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and a connecting portion that extends at least radially outwardly from the top annular mounting portion to the sealing portion.

Abstract: A filter element includes a bottom open end joined to a center tube opposite the top open end. The bottom open end defines a radially outer surface and a radially inner surface that is in communication with the central reservoir of the filter element. A first locking feature is disposed proximate to the bottom open end. The locking feature includes an entrance slot that is disposed on the radially inner surface of the center tube extending axially from the bottom open end. A similar or identical second locking feature is disposed proximate to the top open end.

Abstract: An endcap for a filter element includes an annular plate member disposed adjacent an axial end surface of an annular filter medium of the filter element. A radially outer annular flange projects axially from a surface of the annular plate member. The radially outer annular flange includes a winglet feature extending radially outwardly in a cantilever fashion from an outer circumferential surface of the radially outer annular flange in a direction opposite to a direction in which the filter element is rotated during installation into a filter base of a filter system, with the winglet feature deflecting toward the outer circumferential surface of the radially outer annular flange through contact with a wedge-shaped protrusion projecting radially inwardly from an inner circumference of the filter base as the filter element is rotatably installed into the filter base, and springing back to its undeflected configuration after passing the wedge-shaped protrusion.

Abstract: A filter medium includes a plurality of layers each including an undulating strip of solidified material.

Abstract: A method for manufacturing a filter includes providing a computer-readable three-dimensional model of the filter, the three-dimensional model being configured to be converted into a plurality of slices that each define a cross-sectional layer of the filter, and successively forming each layer of the filter by additive manufacturing.

Abstract: A nonpneumatic tire has at least one spoke loop structure connected to a shear band, wherein the spoke loop structure has a plurality of loops extending inward from the shear band, and wherein each loop is connected to a wheel. A method for forming the nonpneumatic tire includes the step of forming a base and loop subassembly by providing a base having a plurality of grooves, inserting a layer of elastomer strip into each groove and forming a loop between each of the grooves; and inserting the base and loop subassembly which has a plurality of flexible loops extending inward from a shearband so that the base is positioned adjacent the shear band; curing the base and loop subassembly formed from a strip of elastomeric material into the shearband; providing a wheel, and then connecting each loop to the wheel.

Abstract: A method of assembling a canister filter system includes inserting a first filter component into a second filter component, and continuing the insertion until a first tab of either the first filter component or the second filter component contacts the other of the first filter component and the second filter component.

Abstract: A wastewater filter conversion kit for replacing filter elements connected to a shaft includes first and second conveyor segments. Each conveyor segment includes a perforated panel. At least one first tube is secured to a first end of the panel. At least one second tube is secured to a second end of the panel. The least one first tube on the first conveyor segment and the at least one second tube on the second conveyor segment are aligned along a common centerline for receiving the shaft to replace the filter elements on the shaft.
