Abstract
Abstract A catalytic converter device is provided for use in connection with internal combustion engines, stationary turbines and steam boilers, in which a plurality of individually framed and mesh-encased catalyst support tiles, are held in a single basket positioned within the body of the catalytic converter. The catalyst support tiles, individually framed and enclosed in steel mesh, enable the use of thin tiles to improve catalyst efficiency and to facilitate routine maintenance of the converter.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
210 words
A catalytic conversion device for use with internal combustion engines which comprises: (a) a plurality of ceramic catalyst support tiles, each tile having a steel frame on its edges and surrounded on its faces by steel mesh, said plurality of support tiles being secured within a holding basket; (b) a converter body inlet member having an emission inlet which is positioned at the apex of a quadrilateral-based pyramid section of said inlet member, aid inlet member further comprising a catalyst tile-holding, basket-receiving, rectangular mid-section, having basket fastening means at an end of said inlet member distal from said emission inlet wherein said basket fastening means are used to fasten said holding basket to said converter body inlet member; (c) a converter body outlet member having an emission outlet which is positioned at the apex of a quadrilateral-based pyramid section of said outlet member; and, (d) a plurality of high temperature gaskets inserted between said holding basket and said converter body inlet member, and between said holding basket and said converter body outlet member, wherein said catalyst support tile holding basket is received within said converter body inlet member, and said gaskets are positioned about said converter body inlet and outlet members to render the whole catalytic conversion device gas tight.
Claim 2
Dependent Claim
