Abstract
Abstract Means for securing a fragile test element in a mount. A rectangular test element is inserted along an axis normal to the plane of the element and normal to the plane of the mount into a recess in the mount, past overhangs in the walls of the recess. The test element is then rotated about that axis into a position in which corners of the test element extend into undercuts below the overhangs. Various means are disclosed for providing engagement of the mount with the corners of the test element to inhibit further rotation of the test element.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
An article of manufacture comprising: a non-circular, substantially planar, at least partially fragile object; a mount having said object retained therein; walls defining a recess in said mount adapted to permit insertion of said object into said recess along a predetermined axis; at least one overhang above an undercut in said walls, said undercut constructed so that rotation of said object about said axis positions a part of said object within said undercut; means for engaging said part of said object in its rotated position with said mount so that further rotation of said object is inhibited, wherein said means for engaging said object with said mount is at least one point at which said part of said object and said mount are embossed together, whereby said object is secured in said mount.
Claim 2
Dependent Claim
133 words
An article of manufacture comprising: a non-circular, substantially planar, at least partially fragile object; a mount having said object retained therein; walls defining a recess in said mount adapted to permit insertion of said object into said recess along a predetermined axis; at least one overhang above an undercut in said walls, said undercut constructed so that rotation of said object about said axis positions a part of said object within said undercut; means for engaging said part of said object in its rotated position with said mount so that further rotation of said object is inhibited, wherein said means for engaging said object with said mount is at least one point at which said part of said object and said mount are embossed together, whereby said object is secured in said mount.
Claim 3
Dependent Claim
144 words
An article of manufacture comprising: a non-circular, substantially planar, at least partially fragile object; a mount having said object retained therein; walls defining a recess in said mount adapted to permit insertion of said object into said recess; at least one overhang above an undercut in said walls, said undercut constructed so that rotation of said object about said axis positions a part of said object within said undercut; a camming wall in said undercut adapted to guide the object into said position; and means for engaging said part of said object in its rotated position with said mount so that further rotation of said object is inhibited, wherein said means for engaging said object with said mount is at least one point at which said part of said object and said mount are embossed together, whereby said object is secured in said mount.
