Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
72 words
Continuous weighing apparatus comprising a weighing platform, a carrier belt for moving an article across the weighing platform and a stationary feed platform over which the belt moves and which is interleaved with the weighing platform, means for angularly adjusting said feed platform relative to the weighing platform to vary the angle at which the platforms intersect and hence the length of the carrier belt which is unsupported by the weighing platform.
Claim 2
Dependent Claim
72 words
Continuous weighing apparatus comprising a weighing platform, a carrier belt for moving an article across the weighing platform and a stationary feed platform over which the belt moves and which is interleaved with the weighing platform, means for angularly adjusting said feed platform relative to the weighing platform to vary the angle at which the platforms intersect and hence the length of the carrier belt which is unsupported by the weighing platform.
Claim 3
Dependent Claim
14 words
Apparatus as claimed in claim 1, wherein the platforms comprise series of interlocking fingers.
Claim 4
Dependent Claim
37 words
Apparatus as claimed in claim 1, wherein the carrier belt is driven by a drive belt, which is itself driven from a prime mover and makes frictional engagement with portions of the underside of the carrier belt.

Dependent Claim
28 words
Apparatus as claimed in claim 3, wherein the carrier belt is made of a material selected from the group consisting essentially of polyester material and filled woven material.
Claim 6
Dependent Claim
28 words
A belt conveyor as claimed in claim 3, wherein the drive belt passes through and under the weighing platform before being led back to support the carrier belt.
Claim 7
Dependent Claim
28 words
A belt conveyor as claimed in claim 3, wherein the drive belt is driven by a toothed roller engaging teeth on the inner side of the drive belt.
Claim 8
Dependent Claim
15 words

A belt conveyor as claimed in claim 3, wherein the drive belt comprises a series of spaced parallel strips.
Claim 12
Dependent Claim
56 words
A belt conveyor as claimed in claim 10, and including weighing or other sensitive apparatus as claimed in claim 2 wherein the drive belt strips pass over and round the fingers of the feed platform so that the carrier belt is unsupported as it passes over the exposed surfaces of the fingers of the sensitive platform.
Claim 13
Dependent Claim
21 words
A belt conveyor as claimed in claim 11, wherein the feed platform is on the infeed side of the sensitive platform.
Claim 14
Dependent Claim
22 words
A belt conveyor as claimed in claim 3, including a drive belt supporting the carrier belt on each side of the platform.
Claim 15
Dependent Claim
37 words
A belt conveyor as claimed in claim 3, wherein the carrier and drive belts are arranged so that there is a mechanical interlock therebetween provided by surface indentations of the weave of the material of the belts.
Claim 16
Dependent Claim
19 words
Apparatus as claimed in claim 1, wherein the feed platform is on the infeed side of the weighing platform.
