Abstract
Abstract An apparatus is provided for the sequential combined measurement of height (or thickness) and compression strength of successive tablet specimens. The apparatus comprises a specimen-fed chute for depositing the specimens on a conveyor for oriented transport to a measuring station where the tablet height and then its compressive strength are determined. The conveyor is provided with cleansing means for removing the tablet remnants from the compression measurement.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
144 words
An apparatus for the combined measurement of the thickness and the compression strength of tablet-shaped specimens comprising a conveyor including a rotatable disc, feeding means for orienting said specimens on said conveyor, a specimen measuring station located on said conveyor downstream from said feeding means and equipped with means for thickness and compression strength measurement, said station including cleaning means for removing and cleaning from said station substantially all remnants of specimens from the compression strength measurement means, said measurement and cleaning means being serially activated, said measuring station further including a stop member adapted to stop said specimen on said conveyor at said station, and said conveyor also including a resiliently mounted brake adapted to stop the conveyor when said specimen reaches said stop member and then remove the conveyor backwards a small distance sufficient to clear said specimen from said stop member.
Claim 2
Independent Claim
144 words
An apparatus for the combined measurement of the thickness and the compression strength of tablet-shaped specimens comprising a conveyor including a rotatable disc, feeding means for orienting said specimens on said conveyor, a specimen measuring station located on said conveyor downstream from said feeding means and equipped with means for thickness and compression strength measurement, said station including cleaning means for removing and cleaning from said station substantially all remnants of specimens from the compression strength measurement means, said measurement and cleaning means being serially activated, said measuring station further including a stop member adapted to stop said specimen on said conveyor at said station, and said conveyor also including a resiliently mounted brake adapted to stop the conveyor when said specimen reaches said stop member and then remove the conveyor backwards a small distance sufficient to clear said specimen from said stop member.
Claim 3
Dependent Claim
70 words
The apparatus of claim 1, wherein said disc is fitted with a resiliently mounted brake and includes a brake shoe acting on said disc and mounted for limited circumferential movement therewith, and a tangentially mounted spring adapted, on arrest of said disc, to deform and by its resilience rotate the disc backwards by a small amount in roder to clear the test specimen from the brake actuating the stop means.
