Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
82 words
A rack for receiving open-ended tubular cannisters for storing radioactive nuclear fuel cells, said rack comprising a plurality of reticulated vertically spaced horizontally extending rigid frame assemblies, vertical tension rods extending between the top, bottom and intermediate frame assemblies, vertical tubular spacer elements through which said rods pass, extending between adjacent frame assemblies with their ends in abutment therewith, and diagonal tension braces extending between adjacent frame assemblies and connected at their ends to said frame assemblies substantially at the corners thereof.
Claim 2
Dependent Claim
82 words
A rack for receiving open-ended tubular cannisters for storing radioactive nuclear fuel cells, said rack comprising a plurality of reticulated vertically spaced horizontally extending rigid frame assemblies, vertical tension rods extending between the top, bottom and intermediate frame assemblies, vertical tubular spacer elements through which said rods pass, extending between adjacent frame assemblies with their ends in abutment therewith, and diagonal tension braces extending between adjacent frame assemblies and connected at their ends to said frame assemblies substantially at the corners thereof.
Claim 3
Dependent Claim
25 words
A rack as defined in claim 1 in which said braces are detachably connected to said frames to provide for on-site assembly of said racks.
Claim 4
Dependent Claim
50 words
A rack as defined in claim 1, in which said vertical tension rods are headed at one end to engage a frame assembly, and threaded at the other end to receive nuts, said nuts being effective to tension the rods and thus to apply compressive forces to the spacing tubes.
Claim 5
Dependent Claim
25 words
A rack as defined in claim 3, in which said rods fit snugly within said tubes so that said tubes and rods reinforce each other.
Claim 6
Dependent Claim
38 words
A rack as defined in claim 1, in which each of said frame assemblies comprise a plurality of crossing bars, said bars having interfitting notches at crossing points dimensioned to interfit to provide rigidity to said frame assemblies.
Claim 7
Dependent Claim
19 words
A rack as defined in claim 5, in which said crossing bars are additionally welded together at crossing points.
Claim 8
Dependent Claim
38 words
A rack as defined in claim 4, in which each of said frame assemblies comprise a plurality of crossing bars, said bars having interfitting notches at crossing points dimensioned to interfit to provide rigidity to said frame assemblies.
Claim 9
Dependent Claim
19 words
A rack as defined in claim 7, in which said crossing bars are additionally welded together at crossing points.
