Abstract
Abstract The quantity of a liquid vapor in a gas is controlled by mixing a first stream of gas saturated with the liquid vapor and a second stream of dry gas. The flow rate of each of the streams of gas and/or the temperature of the liquid vaporized into the gas determine the percent of the liquid vapor in the mixed stream of gas.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
129 words
An apparatus for controlling the quantity of a vapor in a gas including: means to vaporize a liquid; first means to supply a first stream of dry gas to said vaporizing means to saturate the first stream of gas with the vapor; second means to direct the saturated gas from said vaporizing means; third means to supply a second stream of dry gas; means communicating with said second means and said third means for mixing the gas in said third means with the saturated gas in said second means to form a single stream of gas partially saturated with the vapor; and means to prevent condensation of the vapor in the saturated gas during its flow from said vaporizing means through said second means and through said mixing means.
Claim 2
Dependent Claim
35 words
The apparatus according to claim 2 including means to vary the supply of at least one of the two streams of dry gas to vary the percent of vapor in tHe mixed stream of gas.
Claim 3
Dependent Claim
25 words
The apparatus according to claim 3 in which said varying means includes means to vary the supply of both of the streams of dry gas.
Claim 4
Dependent Claim
22 words
The apparatus according to claim 2 in which said vaporizing means includes means to vary the temperature of the liquid being vaporized.
Claim 5
Dependent Claim
22 words
The apparatus according to claim 4 in which said vaporizing means includes means to vary the temperature of the liquid being vaporized.
Claim 6
Dependent Claim
22 words
The apparatus according to claim 6 in which said mixing means includes means to produce a back pressure in said second means.
Claim 7
Independent Claim
216 words
An apparatus for controlling the quantity of a vapor in a gas including: means to vaporize a liquid; first means to supply a first stream of dry gas to said vaporizing means to saturate the first stream of dry gas with the vapor; second means to direct the saturated gas from said vaporizing means; third means to supply a second stream of the dry gas separate from the first stream of dry gas; said third means including a passage into which said second means extends; said second means terminating in a nozzle disposed within said passage; said passage having a minimum restricted orifice; means to stop the supply of the first stream of dry gas to said vaporizing means; and said nozzle of said second means having its outlet end disposed at said orifice to produce mixing in said passage of the saturated gas in said second means with the dry gas from said third means to form a single stream of gas partially saturated with the vapor and to create a back pressure in said second means to prevent flow from said vaporizing means through said second means when said stopping means stops flow of the first stream of dry gas to said vaporizing means while flow of the second stream of dry gas continues.
Claim 8
Dependent Claim
39 words
The apparatus according to claim 2 in which: said first means has its lower end extending beneath the level of the liquid in said reservoir; and said lower end of said first means has a relatively small outlet orifice.
Claim 9
Dependent Claim
91 words
The apparatus according to claim 2 in which: said vaporizing means includes: a reservoir of liquid; jacket means surrounding said reservoir in spaced relation thereto; means to pass a liquid through the space between said jacket means and said reservoir in heat transfer relation with the liquid in said reservoir; and means to control the temperature of the liquid passing through the space between said jacket means and said reservoir to produce the desired vaporization of the liquid within said reservoir by regulating the temperature of the liquid within said reservoir.
Claim 10
Independent Claim
87 words
A method of supplying a gas having a controlled quantity of a vapor therein including: passing a stream of dry gas into contact with a vaporizing liquid with which the dry gas has had no previous contact; varying the temperature of the vaporizing liquid to vary the percent of the vapor in the gas by varying the temperature of a liquid in heat exchange relation therewith; conveying the gas with the vapor therein from the vaporizing liquid; and preventing condensation of the vapor in the conveying gas.
Claim 11
Independent Claim
122 words
A method of supplying a gas having a controlled quantity of a vapor therein including: passing a first stream of a dry gas into contact with a vaporizing liquid; controlling the conditions of vaporizing the liquid to control the amount of vapor entrained in the gas; passing a second stream of the dry gas into contact with the moisture laden first stream of gas to form the supply of gas; controlling the flow rate of at least one of the first and second streams to control the percent of vapor in the supply gas; and preventing condensation of the vapor before and after the second stream of the dry gas is passed in contact with the moisture laden first stream of gas.
Claim 12
Dependent Claim
53 words
The apparatus according to claim 2 in which said preventing means includes means to control the temperature of the secOnd stream of the dry gas to prevent condensation of the vapor when the second stream of the dry gas is mixed in said mixing means with the saturated gas in said second means.
Claim 13
Dependent Claim
46 words
The apparatus according to claim 2 including: means to convey the single stream of gas partially saturated with the vapor from said mixing means; and said preventing means including means to prevent condensation of the vapor in the single stream of gas in said conveying means.
Claim 14
Dependent Claim
41 words
The method according to claim 12 including controlling the temperature of the second stream of dry gas to prevent condensation of vapor in the first stream of gas when the second stream of dry gas contacts the first stream of gas.
Claim 15
Independent Claim
170 words
An apparatus for controlling the quantity of a vapor in a gas including: means to vaporize a liquid; first means to supply a first stream of dry gas to said vaporizing means to saturate the first stream of gas with the vapor; second means to direct the saturated gas from said vaporizing means; third means to supply a second stream of the dry gas separate from the first stream of dry gas; means for mixing the gas in said third means with the saturated gas in said second means to form a single stream of gas partially saturated with the vapor; means to stop the supply of the first stream of dry gas to said vaporizing means; and said mixing means including means to produce a back pressure in said second means to prevent flow from said vaporizing means through said second means when said stopping means stops flow of the first stream of dry gas to said vaporizing means while flow of the second stream of dry gas continues.
Claim 16
Dependent Claim
43 words
The apparatus according to claim 8 in which: said vaporizing means includes a reservoir of liquid; and said second means includes a riser having its lower end disposed above the level of the liquid in said reservoir, said riser communicating with said nozzle.
