Abstract
Abstract A method and apparatus is disclosed for removing air-in-excessof-saturation from water samples to be measured qualitatively. Pressurized air is bubbled throughout the water sample, thereby sweeping air-in-excess-of-saturation from the water sample into the bubbling pressurized air. The air bubbles are then withdrawn from the sample, leaving a water sample substantially free of air-in-excess-of-saturation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
Apparatus adapted for use in removing air-in-excess-ofsaturation from a water sample to be measured, comprising: an air-sweep container, having an inlet through which the water sample to be measured enters, and having an outlet through which the water sample to be measured exits; an air-release stone, positioned within said air-sweep container such that air bubbles emanating from said air-release stone sweep through the entirety of a water sample present within said air-sweep container; a separation container, positioned so as to receive combined water sample, air bubble effluent from the outlet of said airsweep container, adapted to permit the floatable separation of the air bubbles from the water sample; and overflow withdrawal means, attached to said separation container, through which the separated air bubbles are withdrawn from said separation container, thereby resulting in a water sample within said separation container free of air-inexcess-of-saturation.
Claim 2
Dependent Claim
142 words
Apparatus adapted for use in removing air-in-excess-ofsaturation from a water sample to be measured, comprising: an air-sweep container, having an inlet through which the water sample to be measured enters, and having an outlet through which the water sample to be measured exits; an air-release stone, positioned within said air-sweep container such that air bubbles emanating from said air-release stone sweep through the entirety of a water sample present within said air-sweep container; a separation container, positioned so as to receive combined water sample, air bubble effluent from the outlet of said airsweep container, adapted to permit the floatable separation of the air bubbles from the water sample; and overflow withdrawal means, attached to said separation container, through which the separated air bubbles are withdrawn from said separation container, thereby resulting in a water sample within said separation container free of air-inexcess-of-saturation.
Claim 3
Dependent Claim
15 words
Apparatus according to claim 1, wherein said water sample is a continuously flowing water sample.
Claim 4
Dependent Claim
32 words
Apparatus according to claim 2, further including heating means to heat the water sample to the temperature at which measurements are to be taken, before the water sample enters said air-sweep container.
Claim 5
Dependent Claim
25 words
Apparatus according to claim 3, wherein said overflow withdrawal means is adapted to additionally provide a constant head of water sample within said separation container.
Claim 6
Dependent Claim
13 words
Apparatus according to claim 4, wherein said separation container is vented to atmosphere.
Claim 7
Dependent Claim
42 words
In combination with a measuring device for continuously measuring the quality of a continuously flowing water sample, the improvement resulting in the avoidance of incorrect measurement instrumentation readings from air bubbles within the water sample, comprising an apparatus according to claim 5.
