Abstract

Abstract An integral, thin wall thermoplastic chemical analysis tube module has a plurality of test tubular receptacles disposed normally to an elongated rectangular planar area and has a surrounding first wall frame segment of uniform height secured to and supportively disposed around a perimeter major segment of the planar area. A first uniform stiffener lip is integrally secured to and disposed around the first frame segment opposite the planar area. An opposed pair of second wall frame segments having a second uniform height is secured to and supportively oppositely disposed around a pair of opposed perimeter minor segments of the planar area. The second wall height is precisely greater than the first wall height. A pair of second uniform stiffener lips is secured to and disposed around the second frame segment perimeter, also opposed to the planar area. The temporary compressive displacement of the second pair of stiffener lips inside the perimeter of the first pair of stiffener lips provides an expansive precise jaw clamp on release of the clamp, which can secure the tube module combination in a configured cut out aperture in a supporting plate.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 23 words
A chemical analysis tube module as set forth in claim 1 wherein said plurality of test tubular receptacles range from two to seven.
Claim 2
Dependent Claim 25 words
A chemical analysis tube module as set forth in claim 1 wherein each test tubular receptacle ranges from a volume of 2 to 20 milliliters.
Claim 3
Dependent Claim 37 words
A chemical analysis tube module as set forth in claim 1 wherein a signal land area is disposed across said elongated line of symmetry adjacent to and being a minor fractional area of said rectangular planar area.
Claim 4
Dependent Claim 62 words
A chemical analysis tube module as set forth in claim 1 wherein a thermoplastic cover plate having indexing means coplanarly securing said cover to said rectangular planar area has a cover aperture disposed over each test tubular receptacle aperture, each said cover aperture formed of a plurality of thin, flexible, radial sector divisions flexibly hinged to the perimeter of said cover aperture.
Claim 5
Dependent Claim 260 words
In an integral, thin wall, thermoplastic chemical analysis tube module having an elongated rectangular planar area to which a plurality of test tubular receptacles of uniform apertures are normally secured along the elongated line of symmetry and having a thin wall frame which is supportively disposed around the planar area perimeter, the combination comprising: a first wall frame segment of uniform height, forming a major fractional segment perimeter of said planar area, a first uniform stiffener lip integrally secured to and disposed around the perimeter of said first frame segment, opposed to said planar area, an opposed pair of second wall frame segments, each one having a second uniform height, supportively oppositely disposed around a pair of minor fractional segment perimeters of said planar area, said second wall height precisely greater than said first wall height, a pair of second uniform stiffener lips integrally secured to and disposed around said pair of second frame segment perimeters opposed to said planar area, said first frame segment, first lip, pair of second frame segments, and pair of second lips providing a flexible hinge displacement of said opposed pair of second frame segments with respect to said first frame segment on application of compressive force to said pair of second segments, said hinge displacement suitable for an unclamping and a clamping movement of said lips in a configured cut-out aperture, and the lip height difference between said first and said second stiffener lips providing a precise jaw clamp, rigidly securing said tube module combination in said configured cut-out aperture in a supporting plate.
Claim 6
Dependent Claim 37 words
A chemical analysis tube module as set forth in claim 6 wherein a signal land area is disposed across said elongated line of symmetry, adjacent to and being a minor fractional area of said rectangular planar area.
Claim 7
Dependent Claim 62 words
A chemical analysis tube module as set forth in claim 6 wherein a thermoplastic cover plate having indexing means coplanarly securing said cover to said rectangular planar area has a cover aperture disposed over each test tubular receptacle aperture, each said cover aperture formed of a plurality of thin, flexible, radial sector divisions flexibly hinged to the perimeter of said cover aperture.
