Abstract
Abstract A manifold thermal reactor is disclosed having a twisted ribbon core forming a double helical flow path. The helix is positioned within the manifold so that the inlet ports all feed into the same continuous chamber, the end of the helix at the exhaust system port being closed while the opposite end of the helix is opened, whereby the gases entering the reactor travel in the same chamber to the open end of the helix where the gas flow is reversed, thereby causing the gases to enter the other chamber formed by the double helix which directs the flow of gases axially of the manifold to the exhaust system port.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
A manifold comprising: a cylindrical casing enclosed at both ends forming an elongated chamber; a divider plate having a central core with helicoidal vanes subdividing the interior of said chamber, and partitioning one end of said chamber, said dividing plate extending transversely through said chamber and cooperating to form an open plenum at the other end thereof so as to form a double helicoidal chamber having first and second flow paths, said flow paths being communicably coupled at said plenum; an inlet port extending through the wall of said casing and communicably coupled to said first helicoidal flow path; and an outlet port extending through the wall of said casing positioned substantially at the partitioned end of said chamber and communicably coupled to said second helicoidal flow path.
Claim 2
Dependent Claim
128 words
A manifold comprising: a cylindrical casing enclosed at both ends forming an elongated chamber; a divider plate having a central core with helicoidal vanes subdividing the interior of said chamber, and partitioning one end of said chamber, said dividing plate extending transversely through said chamber and cooperating to form an open plenum at the other end thereof so as to form a double helicoidal chamber having first and second flow paths, said flow paths being communicably coupled at said plenum; an inlet port extending through the wall of said casing and communicably coupled to said first helicoidal flow path; and an outlet port extending through the wall of said casing positioned substantially at the partitioned end of said chamber and communicably coupled to said second helicoidal flow path.
Claim 3
Dependent Claim
32 words
The manifold of claim 1 including a plurality of said inlet ports transversely spaced along and extending through the wall of said chamber and communicably coupled to said first helicoidal flow path.
Claim 4
Dependent Claim
13 words
The Manifold of claim 1 wherein the wall of said chamber is insulated.
Claim 5
Dependent Claim
24 words
The manifold of claim 3 wherein said casing comprises a doubled wall cylinder having dead space therebetween with insulation positioned around the wall thereof.
Claim 6
Dependent Claim
15 words
The manifold of claim 1 wherein said divider plate is constructed from a ceramic material.
Claim 7
Dependent Claim
15 words
The manifold of claim 1 wherein said cylindrical casing is constructed from a ceramic material.
Claim 8
Dependent Claim
14 words

Claim 9
Dependent Claim
145 words
An internal combustion engine having a combustion chamber with an exhaust connection communicating with a manifold comprising: a cylindrical casing enclosed at both ends forming an elongated chamber a divider plate having a central core with helicoidal vanes subdividing the interior of said chamber and partitioning one end of said chamber, said divider plate extending transversely through said chamber and cooperating to form an open plenum at the other end thereof so as to form a double helicoidal chamber having first and second flow paths, said flow paths being communicably coupled at said plenum; an inlet port extending through the wall of said casing and communicably coupling the exhaust connection to said first helicoidal flow path; and an outlet port extending through the wall of said casing positioned substantially at the partitioned end of said chamber and communicably coupled to said second helicoidal flow path.
Claim 10
Dependent Claim
145 words
An internal combustion engine having a combustion chamber with an exhaust connection communicating with a manifold comprising: a cylindrical casing enclosed at both ends forming an elongated chamber a divider plate having a central core with helicoidal vanes subdividing the interior of said chamber and partitioning one end of said chamber, said divider plate extending transversely through said chamber and cooperating to form an open plenum at the other end thereof so as to form a double helicoidal chamber having first and second flow paths, said flow paths being communicably coupled at said plenum; an inlet port extending through the wall of said casing and communicably coupling the exhaust connection to said first helicoidal flow path; and an outlet port extending through the wall of said casing positioned substantially at the partitioned end of said chamber and communicably coupled to said second helicoidal flow path.
Claim 11
Dependent Claim
30 words
The manifold of claim 1 wherein said inlet port is angularly positioned and aligned coextensive with said first helicoidal flow path to provide a gas flow channel substantially parallel thereto.
