Abstract
Abstract A weighing system in which a force or weight is transmitted downward from a laterally stabilized weighing platform to a laterally stabilized load cell through a ball positioned between a concave region in a bottom end of the platform and a top end of the load cell.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
209 words
A weighing system comprising: a mounting base; weight sensing means having a bottom portion supported by said mounting base and a top portion having a concave top region adapted to receive vertically downward forces, and said weight sensing means including means for providing an electrical output responsive to said forces; a weighing platform adapted to be rigidly connected to a body to be weighed; force transmission means for coupling said weighing platform to said weight sensing means comprising: a vertically positioned force coupling member, a top portion of which is attached to said weighing platform and a bottom portion of which includes a concave region facing said concave region of said weight sensing means, and a ball positioned to contact and rest between said concave regions of said weighing platform and said weight sensing means, whereby forces transmitted by said weighing platform passes through said ball; stabilizing means comprising: a support member supported by said mounting base, first diaphragm means connecting said weight sensing means to said support means for laterally stabilizing said weight sensing means, and second diaphragm means connecting said force transmission means and said support means for laterally stabilizing said force transmission means; whereby transmission of non-vertical forces to said weight sensing means is substantially attenuated.
Claim 2
Dependent Claim
209 words
A weighing system comprising: a mounting base; weight sensing means having a bottom portion supported by said mounting base and a top portion having a concave top region adapted to receive vertically downward forces, and said weight sensing means including means for providing an electrical output responsive to said forces; a weighing platform adapted to be rigidly connected to a body to be weighed; force transmission means for coupling said weighing platform to said weight sensing means comprising: a vertically positioned force coupling member, a top portion of which is attached to said weighing platform and a bottom portion of which includes a concave region facing said concave region of said weight sensing means, and a ball positioned to contact and rest between said concave regions of said weighing platform and said weight sensing means, whereby forces transmitted by said weighing platform passes through said ball; stabilizing means comprising: a support member supported by said mounting base, first diaphragm means connecting said weight sensing means to said support means for laterally stabilizing said weight sensing means, and second diaphragm means connecting said force transmission means and said support means for laterally stabilizing said force transmission means; whereby transmission of non-vertical forces to said weight sensing means is substantially attenuated.
Claim 3
Dependent Claim
25 words
A weighing system as set forth in claim 1 wherein the degree of curvature of said concave regions is less than that of said ball.
Claim 4
Dependent Claim
49 words
A weighing system as set forth in claim 2 wherein said support member is cylindrical and extends upward and around said weight sensing means and said force transmission means, and said second diaphragm means comprises a pair of diaphragms interconnecting said support member to and said force transmission means.
