Abstract

Abstract A thermal separator is provided using a mechanical distributor which is suitable for transforming a continuous supply of gas under pressure originating from a suitable source into a pulsed gas flow, in order to place under pulsatory operating conditions one or several operational receiving tubes connected to this distributor, the relative geometrical arrangement of the source, distributor and receiving tubes being such that the gas under pressure passes, during its passage through the distributor, in a direction which extends from the outside towards the inside of the distributor.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 141 words
A thermal separator comprising: an upstream-located continuous pressure gas supply, at least one downstream-located pulse tube designed to work under gaseous pulsatory running conditions when fed with gas from the upstream-located continuous pressure gas supply, a mechanical distributor interposed between said upstream-located continuous pressure gas supply and said downstream-located pulse tube, said mechanical distributor including movable material having means having peripherally-located input means connected to said upstream-located continuous pressure gas supply, centrally-located output means connected to said downstream-located pulse tube, and intermediate duct means connecting said peripherally-located input means with said centrally located output means, whereby the pressure gas progresses through said mechanical distributor in a direction from the outside towards the inside thereof in travelling from said peripherally-located input means through said intermediate duct means up to said centrally-located output means to issue therefrom into said downstream located pulse tube.
Claim 2
Dependent Claim 141 words
A thermal separator comprising: an upstream-located continuous pressure gas supply, at least one downstream-located pulse tube designed to work under gaseous pulsatory running conditions when fed with gas from the upstream-located continuous pressure gas supply, a mechanical distributor interposed between said upstream-located continuous pressure gas supply and said downstream-located pulse tube, said mechanical distributor including movable material having means having peripherally-located input means connected to said upstream-located continuous pressure gas supply, centrally-located output means connected to said downstream-located pulse tube, and intermediate duct means connecting said peripherally-located input means with said centrally located output means, whereby the pressure gas progresses through said mechanical distributor in a direction from the outside towards the inside thereof in travelling from said peripherally-located input means through said intermediate duct means up to said centrally-located output means to issue therefrom into said downstream located pulse tube.
Claim 3
Dependent Claim 91 words
Mechanical distributor as recited in claim 1, further comprising: a stationary outer casing extending around said movable material valving means and having localized port means formed therethrough for periodic registration with said peripherally-located input means, at least one of said port means and said input means being of a size which is reduced in the direction of relative movement of said valving means, whereby, upon said relative movement, full registration of said port means and said input means for fluid flow therethrough and full nonregistration thereof for obturation occur almost instantaneously.
Claim 4
Dependent Claim 47 words
Mechanical distributor as recited in claim 2, wherein said at least one of said localized port means and said input means is in the form of a long and narrow rectangular slot, the narrowness of which lies in the direction of relative movement of said valving means.
Claim 5
Dependent Claim 18 words
Mechanical distributor as recited in claim 1, wherein said movable material valving means is a rotary valve plug.
Claim 6
Dependent Claim 19 words
Mechanical distributor as recited in claim 1, wherein said movable material valving means is a rectilinearly reciprocating slide valve.
Claim 7
Dependent Claim 19 words
Mechanical distributor as recited in claim 5, further comprising: spring means for effecting the reciprocation of said slide valve.
Claim 8
Dependent Claim 14 words
Mechanical distributor as recited in claim 6, wherein said spring means is a gas.
