Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
132 words
Apparatus for separating solids from liquids including means defining a plurality of parallel tubes comprising: a. a member having a series of spaced-apart slot means defined on a first surface thereof; b. generally flat ribs extending from the opposite surface of said member, each such rib having an edge dimensioned to fit into said slot means; c. at least two of said members being aligned parallel to each other with the respective slot means on each such member being aligned with corresponding slot means on the other member; and d. at least three of said ribs each being received in and secured to the slot means of one of said members so as to define with said two members at least two adjacent tubes for receiving a mixture of liquids and solids.

Claim 3
Dependent Claim
25 words
The invention defined in claim 1 wherein said slot means are defined by intEgral material of each member extending generally parallel to the plane thereof.
Claim 4
Dependent Claim
18 words
The invention defined in claim 2 wherein said ribs are secured to and extend from said integral material.
Claim 5
Dependent Claim
25 words
The invention defined in claim 2 wherein said ribs are integral with said members and extend therefrom on the surface opposite to said integral material.
Claim 6
Dependent Claim
23 words
The invention defined in claim 2 wherein said slot means are T-shaped and said edge of said ribs is T-shaped for fitting thereinto.
Claim 7
Dependent Claim
23 words
The invention defined in claim 2 wherein said slot means are arrowhead-shaped and said edge of said ribs is arrowhead-shaped for fitting thereinto.
Claim 8
Dependent Claim
26 words
The invention defined in claim 1 wherein said slot means each are defined by two integral material projections extending perpendicular to the surface of said member.
Claim 9
Dependent Claim
11 words
The invention defined in claim 1 wherein said members are planar.
Claim 10
Dependent Claim
11 words
The invention defined in claim 1 wherein said members are curved.
Claim 11
Dependent Claim
24 words
The invention defined in claim 9 wherein said members each comprise a series of identical curved segments intersecting at cusps which define slot means.
Claim 12
Dependent Claim
25 words
The invention defined in claim 1 wherein said members comprise flat intersecting segments which meet at angles, the vertices of which define said slot means.
Claim 13
Dependent Claim
28 words
The invention defined in claim 1 in which said slot means is defined by integral material located at the end of short ribs extending from said first surface.
Claim 14
Dependent Claim
17 words
The invention defined in claim 1 wherein said ribs are thicker than the remainder of said member.
Claim 15
Dependent Claim
19 words
The invention defined in claim 11 wherein the endmost ribs on each member are offset toward the center thereof.
