Abstract
Abstract A flexible technique for modifying various chemical substances utilizes a confined path to be followed by these substances in gaseous form or in a gaseous medium. Along this path there is positioned electrically energizeable means for establishing an electric field. Also along the path there are positioned electrically energizeable means for heating the gas to crack certain constituents into free elements; for combusting certain constituents; and for attracting certain constituents through affinity. The electrical energization of these means is controllable to provide the appropriate effect on the substances in the path.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
159 words
A system for modifying chemical substances, comprising: a confined path for said substances; means for preparing said substances for introduction into said path, said preparing means including means for gasifying the substances or finely dividing them and entraining them in a gaseous medium; means for introducing the prepared substances into the path; electrically energizeable means for establishing in a predetermined portion of the path an electric field; a metal having an affinity for at least one said substance, the affinity metal being positioned in the same portion of the path as the field establishing means; electrically energizeable means for establishing an electric arc across another portion of the confined path; and electrically energizeable means positioned in still another part of the path for heating the substances passing therethrough to produce cracking of at least some of the substances into free elements, the arc means and cracking means being both positioned in the path upstream from the electric field means.
Claim 2
Independent Claim
159 words
A system for modifying chemical substances, comprising: a confined path for said substances; means for preparing said substances for introduction into said path, said preparing means including means for gasifying the substances or finely dividing them and entraining them in a gaseous medium; means for introducing the prepared substances into the path; electrically energizeable means for establishing in a predetermined portion of the path an electric field; a metal having an affinity for at least one said substance, the affinity metal being positioned in the same portion of the path as the field establishing means; electrically energizeable means for establishing an electric arc across another portion of the confined path; and electrically energizeable means positioned in still another part of the path for heating the substances passing therethrough to produce cracking of at least some of the substances into free elements, the arc means and cracking means being both positioned in the path upstream from the electric field means.
Claim 3
Dependent Claim
18 words
The system of claim 1, comprising means for adjustably controlling the electrical energization of the arc establishing means.
Claim 4
Dependent Claim
19 words
The system of claim 2, wherein the controlling means comprises means for selectively connecting and disconnecting the electrical energization.
Claim 5
Dependent Claim
36 words
The system of claim 1 comprising a second electrically energizeable means for establishing an electric field in another part of the path, and an affinity metal for another said substance positioned in said other path part.
Claim 6
Dependent Claim
18 words
The system of claim 4 comprising means for adjustably controlling the energization of the second field establishing means.
Claim 7
Dependent Claim
19 words
The system of claim 5, wherein the control means includes means for selectively connecting and disconnecting the electrical energization.
Claim 8
Dependent Claim
17 words
The system of claim 1 comprising means for adjustably controlling the electrical energization of the heating means.
Claim 9
Dependent Claim
19 words
The system of claim 7 wherein the control means includes means for selectively connecting and disconnecting the electrical energization.
Claim 10
Dependent Claim
13 words
The system of claim 1, wherein the gasifying means is heat-actuated evaporating means.
Claim 11
Dependent Claim
19 words
The system of claim 1 further comprising means for adjustably controlling the electrical energization of the field establishing means.
