Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
A slide holder for accommodating a planar specimen slide which comprises: (a) a molded frame to accommodate said slide; (b) integral cooperating slide holding means for retaining said slide defined by said frame; (c) nesting means defined by opposing sides of said frame to cooperate with corresponding nesting means of vertically stacked adjacent slide holders to permit movement of one slide holder in one direction while preventing movement in a direction substantially transverse thereto; and, (d) transport means operatively associated with said frame to permit mechanical transfer of said slide holder.
Claim 2
Dependent Claim
91 words
A slide holder for accommodating a planar specimen slide which comprises: (a) a molded frame to accommodate said slide; (b) integral cooperating slide holding means for retaining said slide defined by said frame; (c) nesting means defined by opposing sides of said frame to cooperate with corresponding nesting means of vertically stacked adjacent slide holders to permit movement of one slide holder in one direction while preventing movement in a direction substantially transverse thereto; and, (d) transport means operatively associated with said frame to permit mechanical transfer of said slide holder.
Claim 3
Dependent Claim
14 words
A slide holder according to claim 1 wherein said frame includes an encoding area.
Claim 4
Dependent Claim
14 words
A slide holder according to claim 2 wherein said encoding area is machine readable.
Claim 5
Dependent Claim
14 words
A slide holder according to claim 2 wherein said encoding area is human readable.
Claim 6
Dependent Claim
17 words
A slide holder according to claim 1 wherein said frame can accommodate a glass planar specimen slide.
Claim 7
Dependent Claim
17 words
A slide holder according to claim 1 wherein said frame can accommodate a plastic planar specimen slide.
Claim 8
Dependent Claim
19 words
A slide holder according to claim 1 wherein said integral cooperating slide holding means includes a resilient biasing means.
Claim 9
Dependent Claim
93 words
A specimen holder which comprises: (a) a planar specimen slide; (b) a molded frame to accommodate said slide; (c) integral cooperating slide holding means for retaining said slide in said frame; (d) nesting means defined by opposing sides of said frame to cooperate with corresponding nesting means of vertically stacked adjacent specimen holders constructed in a range to permit movement of one slide holder in one direction while preventing movement in a direction substantially transverse thereto; and, (e) transport means operatively associated with said frame to permit mechanical transfer of said specimen holder.
Claim 10
Dependent Claim
93 words
A specimen holder which comprises: (a) a planar specimen slide; (b) a molded frame to accommodate said slide; (c) integral cooperating slide holding means for retaining said slide in said frame; (d) nesting means defined by opposing sides of said frame to cooperate with corresponding nesting means of vertically stacked adjacent specimen holders constructed in a range to permit movement of one slide holder in one direction while preventing movement in a direction substantially transverse thereto; and, (e) transport means operatively associated with said frame to permit mechanical transfer of said specimen holder.
Claim 11
Dependent Claim
75 words
A specimen holder which comprises: (a) an integral planar specimen slide; (b) a frame encompassing said slide; (c) nesting means defined by opposing sides of said frame to cooperate with corresponding nesting means of vertically stacked adjacent specimen holders to permit movement of one slide holder in one direction while preventing movement in a direction substantially transverse thereto; and, (d) transport means operatively associated with said frame to permit mechanical transfer of said specimen holder.
Claim 12
