Abstract
Abstract A method and apparatus for supplying a source of a pollutant gas admixed with an inert gas, wherein the inert gas is passed through a passage defined by a permeator body of a distance sufficient to permit the inert gas to reach thermal equilibrium with the permeator body, and the inert gas is subsequently passed through a centrally disposed opening in the permeator body for admixture with a pollutant gas which has diffused through a gaspermeable container positioned in the opening.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
183 words
A permeator assembly to supply a source of a pollutant gas admixed with an inert gas comprising a permeator body including a barrel portion having an elongate groove about the periphery thereof, a casing adapted to receive the barrel portion and having an inner face, with the inner face and the casing groove defining a passage having a high ratio of length to cross sectional area, means to supply an inert gas to said passage communicating with said passage, a centrally disposed opening extending through the body, said opening communicating with said passage opposite the means to supply an inert gas and adapted to receive a pollutant gas permeable container in said opening to diffuse pollutant gas into said opening for admixture with inert gas supplied through said passage to said opening whereby the inert gas supplied to said passage reaches thermal equilibrium with the body and is then passed into said opening to form a mixture of pollutant gas and the inert gas, means to remove the mixture from said opening and means to heat the inert gas supplied to said passage.
Claim 2
Dependent Claim
183 words
A permeator assembly to supply a source of a pollutant gas admixed with an inert gas comprising a permeator body including a barrel portion having an elongate groove about the periphery thereof, a casing adapted to receive the barrel portion and having an inner face, with the inner face and the casing groove defining a passage having a high ratio of length to cross sectional area, means to supply an inert gas to said passage communicating with said passage, a centrally disposed opening extending through the body, said opening communicating with said passage opposite the means to supply an inert gas and adapted to receive a pollutant gas permeable container in said opening to diffuse pollutant gas into said opening for admixture with inert gas supplied through said passage to said opening whereby the inert gas supplied to said passage reaches thermal equilibrium with the body and is then passed into said opening to form a mixture of pollutant gas and the inert gas, means to remove the mixture from said opening and means to heat the inert gas supplied to said passage.
Claim 3
Dependent Claim
23 words
An assEmbly as defined by claim 1 wherein the means to supply an inert gas to said passage includes a small diameter orifice.
Claim 4
Dependent Claim
33 words
An assembly as defined by claim 1 wherein said passage is a helical passage having a length sufficient to permit the inert gas supplied thereto to reach thermal equilibrium with the permeator body.
Claim 5
Dependent Claim
32 words
An assembly as defined by claim 3 wherein the casing includes a sleeve portion adapted to receive the barrel portion of the permeator body and temperature insulating means surrounding the sleeve portion.
Claim 6
Dependent Claim
18 words
An assembly as defined by claim 4 wherein the heating means are positioned adjacent to the sleeve portion.
Claim 7
Dependent Claim
32 words
An assembly as defined by claim 1 wherein the central opening contains a thin film of a material to prevent reaction of the pollutant gas with the material forming the permeator body.
Claim 8
Dependent Claim
37 words
An assembly as defined by claim 5 wherein the barrel portion and the casing define a chamber opposite the means to supply gas to said passage whereby the central opening communicates with said passage through said chamber.
Claim 9
Dependent Claim
29 words
An assembly as defined by claim 1 wherein the means to remove said mixture from the central opening includes means to measure the flow rate of said mixture therethrough.
Claim 10
Dependent Claim
18 words
An assembly as defined by claim 1 which includes means for measuring the temperature of the permeator body.
Claim 11
Dependent Claim
25 words
An assembly as defined by claim 1 wherein the means to heat the inert gas is adjusted to control the temperature of the permeator body.
Claim 12
Dependent Claim
44 words
An assembly as defined in claim 1 wherein the means to remove said mixture from the central opening includes filter means adapted to admit ambient gas to the stream of said mixture removed from the means to remove said mixture from the central opening.
Claim 13
Dependent Claim
137 words
A permeator comprising a body including a barrel portion, an elongate groove about the barrel portion to define a passage having a high ratio of length to cross sectional area, means to supply an inert gas to said passage communicating with said passage, a centrally disposed opening extending through the body, said opening communicating with said passage opposite the means to supply an inert gas and adapted to receive a pollutant gas permeable container in said opening to diffuse pollutant gas into said opening for admixture with inert gas supplied through said passage to said opening whereby the inert gas supplied to said passage reaches thermal equilibrium with the body and is then passed into said opening to form a mixture of pollutant gas and the inert gas, and means to remove the mixture from said opening.
Claim 14
Dependent Claim
137 words
A permeator comprising a body including a barrel portion, an elongate groove about the barrel portion to define a passage having a high ratio of length to cross sectional area, means to supply an inert gas to said passage communicating with said passage, a centrally disposed opening extending through the body, said opening communicating with said passage opposite the means to supply an inert gas and adapted to receive a pollutant gas permeable container in said opening to diffuse pollutant gas into said opening for admixture with inert gas supplied through said passage to said opening whereby the inert gas supplied to said passage reaches thermal equilibrium with the body and is then passed into said opening to form a mixture of pollutant gas and the inert gas, and means to remove the mixture from said opening.
Claim 15
Dependent Claim
23 words
A permeator as defined in claim 12 wherein the means to supply an inert gas to said passage includes a small diameter orifice.
Claim 16
Dependent Claim
30 words
A permeator as defined in claim 12 wherein the permeator body includes a flange portion and a barrel portion, with the passage defined by the periphery of the barrel portion.
Claim 17
Dependent Claim
19 words
A permeator as defined in claim 13 which includes a continuous groove about the periphery of the barrel portion.
Claim 18
Dependent Claim
24 words
A permeator as defined in claim 16 wherein the groove is a helical groove extending over substantially the entire length of the barrel portion.
Claim 19
Dependent Claim
32 words
A permeator as defined by claim 12 wherein the central opening contains a thin film of a material to prevent reaction of the pollutant gas with the material forming the permeator body.
Claim 20
Dependent Claim
29 words
A permeator as defined by claim 12 wherein the means to remove said mixture from the central opening includes means to measure the flow rate of said mixture therethrough.
Claim 21
Dependent Claim
45 words
A permeator as defined by claim 12 wherein the means to remove said mixture from the central opening includes a filter means adapted to admit ambient gas to the stream of said mixture removed from the means to remove said mixture from the central opening.
