Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
A powder moisture meter, comprising: a. an open-mouthed container comprising first and second transparent wall portions, said second wall portion being disposed between said first wall portion and the container mouth; b. first graduated scale means at said first wall portion for calibrating said meter by adjusting according to the particular characteristics of said powder to be tested, the direct determination of the moisture content of said powder; c. second graduated scale means at said second wall portion for directly determining the moisture content of said powder, said second scale means comprising divisions for measuring said moisture content on at least one of a wet weight and dry weight bases, said first scale means permitting the reading of said second scale means to be so adjusted.
Claim 2
Dependent Claim
126 words
A powder moisture meter, comprising: a. an open-mouthed container comprising first and second transparent wall portions, said second wall portion being disposed between said first wall portion and the container mouth; b. first graduated scale means at said first wall portion for calibrating said meter by adjusting according to the particular characteristics of said powder to be tested, the direct determination of the moisture content of said powder; c. second graduated scale means at said second wall portion for directly determining the moisture content of said powder, said second scale means comprising divisions for measuring said moisture content on at least one of a wet weight and dry weight bases, said first scale means permitting the reading of said second scale means to be so adjusted.
Claim 3
Dependent Claim
24 words
A moisture meter as in claim 1, wherein said container comprises substantially opaque further wall portions at substantially the balance of the wall thereof.
Claim 4
Dependent Claim
18 words
A moisture meter as in claim 1, wherein said container comprises a funnel shaped portion at said mouth.
Claim 5
Dependent Claim
71 words
A moisture meter as defined in claim 1, wherein said second scale comprises at least two component scales, a first component scale being linear and a second component scale being non-linear, said linear first component scale providing a moisture content reading on the basis of the wet weight of said powder sample and said second component scale providing said reading on the basis of the dry weight of said powder sample.
Claim 6
Dependent Claim
39 words
A moisture meter as defined in claim 1, wherein said first and second scales are separated by an internal volume of said container substantially equal to the volume of a sample of said powder in a substantially dry condition.
Claim 7
Dependent Claim
43 words
A moisture meter as defined in claim 1, wherein said container defines a volume disposed between said first scale means and the closed end of said container, said volume being at least equal to the amount of liquid required to suspend said powder.
