An apparatus and method for isometric muscle strength testing using a chair apparatus (40) having a support frame structure (42), a seat assembly (46), a foot rest assembly (60) and load cells (100) interconnected to the support frame structure (42) for measuring the isometric force exerted by any of a plurality of muscle groups in a human subject's body. The load cells (100) are possibly positioned on six track systems; a posterior track (80a), left and right lateral tracks (80b,c) an anterior track (80d), a forward upper track (80e) and a forward lower track (80f) to enable alignment with the muscle group selected for testing. A thorax restraint assembly (120), a sacral pad assembly (140), a pelvic restraint assembly (150), a thigh restraint assembly (160) and a calf restraint assembly (170) are present for selectively engaging and immobilizing parts of the human subject's body, including the pelvis, thorax, thighs and legs, as required to enable the muscle group selected for testing to be tested while isolated from the other muscle groups of the human subject's body.

Method and apparatus for measuring the isometric muscle strength of

Disclosed are an apparatus and method for cutting paper sheets into smaller sheet sections and collating the sheet sections. The apparatus includes a table having a longitudinal section, followed by a transverse section. Chains just below the table move a sheet stack longitudinally past a first blade which cuts the stack longitudinally, after which one of the stack portions is elevated above the other and placed on top of the other to combine the portions into a second stack. A second pair of chains moves the second stack in the transverse direction past a second blade which cuts the second stack transversely. One of the stack portions formed by the second cut is elevated above, then placed on top of, the other portion to form a further reduced sized third stack, which then is moved transversely to a third cutting station at which it is cut in the transverse direction. Again, one of the portions created by the third cut is elevated above and placed on the other portion to form a final stack of sheet sections.
