摘要： The invention relates to a closure device (28) for a filter unit (1) for the mutual and releasable insertion into a return air duct or exhaust air duct (2) of a barrier system (3), comprising a main body (30), an opening (6) in the main body (30) that can be peripherally bounded by an annular seal (11), a lid (10) that can be switched between an open position in which the opening (6) is open and a closed position in which it bears in a sealing manner against the annular seal (11) in order to selectively open and close the opening (6) and that has passing through it an imaginary longitudinal axis (A), wherein the lid (10) is connected in an articulated manner to the main body (30) so as to be able to pivot by means of at least one rotary articulation (40) through which there passes a pivot axis (S). The lid (10) is designed so as to be able to pivot at least double-eccentrically, wherein the first eccentricity arises from the fact that the pivot axis (S) is arranged at a distance (A1) from a plane (E1) in which a closure section ( ) of the lid (10) lies, and wherein the second eccentricity arises from the fact that the pivot axis (S) is arranged at a distance (A2) from a vertical longitudinal mid-plane (E2) which passes vertically through the center of the lid (10) when the latter is in its closed position.

摘要： Described herein is a combustion process waste receptacle having a fluid lock that has an open state (in which fluid contaminants can pass into a fluid contaminant reservoir) and a closed state (in which fluid contaminants are prevented from entering into a fluid contaminant reservoir). The fluid lock preferably transitions from the open state to the closed state when the fluid contaminant reservoir is full. The fluid lock preferably includes a float chamber and a floatable float.

摘要： Filter media for a drum filter that includes a plurality of annular frame members, each annular frame member having a circumference is disclosed. The filter media includes a filter sheet with first and second engagement strips having a cord portion and an attachment tab portion connected to the filter sheet. The first and second engagement strips engage with first and second connecting strips located on the annular frame members. Each connecting strip has a receiving portion that receives the cord portion of the associated engagement strip. Each connecting strip also has a body portion configured to engage a drum filter frame. An engagement mechanism configured to attach a filter sheet to a drum filter frame is also disclosed. A system for attaching a filter media to a cylindrical drum filter is also disclosed. When the first and second engagement strips are fully received in the first and second connecting strips, the filter media extends between the first annular frame member and second annular frame member and along the first and second circumferential edges to enclose a first cylindrical filter space.

摘要： An apparatus and method are provided for a flangeless air filter configured to be mounted onto a flat surface within an air intake system of an internal combustion engine. The flangeless air filter is comprised of a cone-shaped filter medium, retained between a base and a cap, that is fabricated to remove contaminants and particulate matter from an intake airstream. The base includes a pliable seal that forms an airtight connection between the flangeless air filter and the flat surface of the air intake system. A mounting bracket and fasteners may be used to attach the base to the flat surface, compressing the seal there between. In some embodiments, the mounting bracket may be incorporated into, and made a part of the base. A cap is disposed on a top of the flangeless air filter and configured to direct the intake airstream around the cap and toward the filter medium.
