Abstract
Abstract An arrangement including at least one pair of load cells capable of continuously determining the quantity of material contained within a reservoir and wherein the reservoir support framework will normally convey the load through both cells and includes structural members which can be positioned to by-pass the load around a defective cell and permit the removal thereof without interrupting the operation of the other cell.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
71 words
In combination with a material transport system including at least one reservoir for accumulating a predetermined quantity of material, at least one pair of load monitors capable of continuously determining the quantity of material contained within said reservoir, and support structure normally conveying the reservoir load through both of the monitors, said support structure including means allowing replacement of one of the monitors without interruption of operation of said other monitor.
Claim 2
Dependent Claim
71 words
In combination with a material transport system including at least one reservoir for accumulating a predetermined quantity of material, at least one pair of load monitors capable of continuously determining the quantity of material contained within said reservoir, and support structure normally conveying the reservoir load through both of the monitors, said support structure including means allowing replacement of one of the monitors without interruption of operation of said other monitor.
Claim 3
Dependent Claim
12 words

Claim 4
Dependent Claim
15 words
The combination according to claim 1 wherein said pair comprises spaced upper and lower monitors.
Claim 5
Dependent Claim
18 words
The combination according to claim 3 wherein the support structure means includes elongated upright members straddling said monitors.
Claim 6
Dependent Claim
29 words
The combination according to claim 4 wherein the support structure means includes bearing plates engaged with the upright members and disposed superjacent to said upper and lower monitors, respectively.
Claim 7
Dependent Claim
29 words
The combination according to claim 5 wherein the support structure means includes base plates engaged with the upright members and disposed subjacent to said upper and lower monitors, respectively.
Claim 8
Dependent Claim
14 words
The combination according to claim 6 wherein said upright members include threaded end portions.
Claim 9
Dependent Claim
25 words
The combination according to claim 7 wherein first locknut means engage the upright members intermediate the bearing and base plates associated with the respective monitors.
Claim 10
Dependent Claim
39 words
The combination according to claim 8 wherein under normal operation the first locknut means are respectively spaced a predetermined distance from the base plate associated with the upper monitor and from the bearing plate associated with the lower monitor.
Claim 11
Dependent Claim
33 words

Claim 12
Dependent Claim
36 words
The combination according to claim 10 wherein under normal operation the second locknut means are respectively fitted against the bearing plate associated with the upper monitor and against the base plate associated with the lower monitor.
Claim 13
Dependent Claim
40 words
The combination according to claim 10 wherein replacement of the upper monitor includes said support structure means having corresponding first locknut means fitted against the associated base plate and having corresponding second locknut means spaced from the associated bearing plate.
Claim 14
Dependent Claim
40 words
The combination according to claim 10 wherein replacement of the lower monitor includes said support structure means having corresponding first locknut means fitted against the associated bearing plate and having corresponding second locknut means spaced from the associated base plate.
Claim 15
Dependent Claim
43 words
The combination according to claim 10 wherein replacement of the upper monitor includes said support structure means having corresponding first locknut means fitted against the associated base plate and having corresponding second locknut means and associated bearing plate disengaged from said upright member.
Claim 16
Dependent Claim
