Abstract
Abstract An arrangement for filtering fluid flow includes a T connection having a hollow body connected with two aligned hollow lateral extensions. A plate is secured within and intersects the lateral extensions and has an opening therein to accommodate flow through the lateral projections. A filter member including a hollow core is positioned adjacent the plate and surrounds the opening in the plate for filtering flow through the lateral extensions. The filter member extends from the extensions into the body and is closed off at one end by a flange secured to the body.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
205 words
An arrangement for filtering fluid flow in a conduit comprising: a. a T connection having a hollow body including a hollow projection which is connected with and intersects a pair of aligned hollow lateral extensions for forming a flow passage through the connection; b. flange means formed on said hollow projection; c. a plate secured in said T connection to intersect the flow passage, said plate having an opening therein; d. a hollow, annular filter member positioned in said hollow projection and extending into the flow passage, said filter member including: 1. a core formed of spaced strips; 2. said strips having a surface for receiving the flow of fluid; 3. said strips having converging side surfaces extending from said fluid receiving surface whereby the space between said spaced strips is smallest adjacent the fluid receiving surface; and 4. a plurality of spaced reinforcing ribs engaging said spaced strips; e. said filter member having an end positioned to communicate with the opening in said plate for receiving fluid flow in said filter member; f. closing means for closing the other end of said filter member; and g. retaining means secured to said flange means to retain said filter member in position in said hollow projection.
