Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 151 words
A weighing table especially adapted for use in a roller conveyor comprising in combination: a supporting frame including a plurality of upstanding members, an inner unit for carrying the load to be weighed, a single force transducer having a first part thereof connected to said supporting frame, said inner unit including a plurality of connecting members extending from said inner unit to a further element which is in turn connected to a second part of said force transducer, a plurality of support means each connecting said inner unit to a respective one of said upstanding members adjacent its upper end, each of said support means comprising a thin, flat, flexible member but with high tensile strength, each of said members lying In the same horizontal plain, whereby said force transducer is subject to vertical loads but transverse force components on said inner unit are resisted by said plurality of support means.
Claim 2
Dependent Claim 151 words
A weighing table especially adapted for use in a roller conveyor comprising in combination: a supporting frame including a plurality of upstanding members, an inner unit for carrying the load to be weighed, a single force transducer having a first part thereof connected to said supporting frame, said inner unit including a plurality of connecting members extending from said inner unit to a further element which is in turn connected to a second part of said force transducer, a plurality of support means each connecting said inner unit to a respective one of said upstanding members adjacent its upper end, each of said support means comprising a thin, flat, flexible member but with high tensile strength, each of said members lying In the same horizontal plain, whereby said force transducer is subject to vertical loads but transverse force components on said inner unit are resisted by said plurality of support means.
Claim 3
Dependent Claim 18 words
The apparatus of claim 1 wherein each said connecting member extends downwardly and inwardly toward said further element.
Claim 4
Dependent Claim 21 words
The apparatus of claim 1 wherein said thin, flat, flexible member of each said support means is formed of beryllium copper.
Claim 5
Dependent Claim 31 words
The apparatus of claim 1 wherein said further element comprises a flat plate which on its lower surface supports a V-shaped edge which engages an annular groove formed in said transducer.
Claim 6
Dependent Claim 17 words
The apparatus of claim 4 which further includes means for restraining upward movement of said inner unit.
Claim 7
Dependent Claim 49 words
The apparatus of claim 1 wherein said transducer is of the type wherein said first part comprises a beam supported in cantilever fashion to a second shorter beam comprising said second transducer part, said further element including a V-shaped edge supported in an annular groove in said second beam.
Claim 8
Dependent Claim 23 words
The apparatus of claim 6 wherein said beam comprising said first part supports a strain gauge for sensing deformation in the beam material.
Claim 9
Dependent Claim 33 words
The apparatus of claim 6 wherein said beams included in said transducer are oriented with their axes lying along the direction of movement along said inner unit of an article to be weighed.
