Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
57 words
In a chemical analyzer, an improved cuvette comprising: integrally formed means for defining individual compartments adapted to hold specimens, said compartments being arranged to pass through a line defining a closed curve having a central axis; and window means for transmitting radiant energy through at least some portions of the compartments, whereby the specimens may be analyzed.
Claim 2
Dependent Claim
57 words
In a chemical analyzer, an improved cuvette comprising: integrally formed means for defining individual compartments adapted to hold specimens, said compartments being arranged to pass through a line defining a closed curve having a central axis; and window means for transmitting radiant energy through at least some portions of the compartments, whereby the specimens may be analyzed.
Claim 3
Dependent Claim
25 words
A cuvette, as claimed in claim 1, and further comprising ventilation means for defining an opening within said curve for allowing the passage of air.
Claim 4
Dependent Claim
17 words
A cuvette, as claimed in claim 1, wherein a common plane intersects each of the window means.
Claim 5
Dependent Claim
25 words
A cuvette, as claimed in claim 1, wherein the window means associated with each compartment comprises opposed planar members tHat are parallel to each other.
Claim 6
Dependent Claim
25 words
A cuvette, as claimed in claim 1, wherein the compartments comprise sidewall means and wherein the window means are formed integrally with the sidewall means.
Claim 7
Dependent Claim
19 words
A cuvette, as claimed in claim 1, wherein each compartment comprises bottomwall means that are curved adjacent the compartment.
Claim 8
Dependent Claim
19 words
A cuvette, as claimed in claim 1, wherein the window means are fabricated from material that transmits ultraviolet light.
Claim 9
Dependent Claim
15 words
A cuvette, as claimed in claim 7, wherein the window means are fabricated from acrylic.
Claim 10
Dependent Claim
15 words
A cuvette, as claimed in claim 1, wherein the compartments are interrupted by air spaces.
Claim 11
Dependent Claim
58 words
A cuvette, as claimed in claim 9, and further comprising temperature control means for maintaining the specimens at a predetermined temperature comprising: a bath solution in which the sidewall means are at least partially immersed so that the bath solution enters the air spaces between the compartments; and means for maintaining the bath solution at a constant temperature.
Claim 12
Dependent Claim
35 words
A cuvette, as claimed in claim 2, in combination with additional analyzing apparatus comprising a source of radiant energy located within the area bounded by a vertical projection of said line defining a closed curve.
Claim 13
Dependent Claim
54 words
Apparatus, as claimed in claim 11, and further comprising: rotation means for rotating the cuvette in relationship to the radiant energy source, whereby the radiant energy sequentially passes through the window means in each of said compartments; and means for passing air over the source and through said opening, whereby the source is cooled.
Claim 14
Dependent Claim
36 words
Apparatus, as claimed in claim 12, wherein the source is aligned so that the radiant energy is transmitted perpendicular to the surface of the window means at some time during the operation of the rotation means.
