a drive system connected to the support assembly and configured to move the support assembly, the drive system comprising:
a lead screw attached to the support surface and defining a longitudinal axis; and
an epicyclic gear assembly comprising a carrier and a plurality of rotatable gears, the epicyclic gear assembly rotationally coupled to the lead screw,
wherein operation of the epicyclic gear assembly causes translation of the support assembly along the longitudinal axis.
16. The seat assembly of claim 15, wherein operation of the epicyclic gear assembly causes rotation of the lead screw about the longitudinal axis.
17. The seat assembly of claim 15, wherein operation of the epicyclic gear assembly causes translation of the lead screw along the longitudinal axis.
18. The seat assembly of claim 15, wherein operation of the epicyclic gear assembly causes translation of the carrier along a central carrier axis.
19. The seat assembly of claim 15, wherein the lead screw comprises a shaft and a thread defined on an outer surface of the shaft.
20. The seat assembly of claim 15, wherein the carrier is rotatable about a central carrier axis.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A meat object cutting apparatus comprising:
a supporting frame;
a set of blades securely attached to said supporting frame, wherein the meat object is placed on said blades; and
a pusher head having a number of fingers, one end of said pusher head being pivotally connected to one end of said supporting frame,
wherein said fingers and said blades are shaped to fit said fingers into the spaces between said blades as the angle between said pusher head and said supporting frame decreases and whereby the meat object is sheared and cut by being pushed against and through said blades until said fingers pass through the spaces between said blades.
2. The meat object cutting apparatus according to claim 1, further comprising a force generating means connecting to said pusher head to facilitate close of the angle between said pusher head and said supporting frame.
3. The meat object cutting apparatus according to claim 2, wherein said blades comprising at least one blade orthogonal to the pivotal connection between said pusher head and said supporting frame.
4. The meat object cutting apparatus according to claim 2, wherein said blades further comprising at least one blade parallel to the pivotal connection between said pusher head and said supporting frame.
5. The meat object cutting apparatus according to claim 1, wherein said blades are of being serrate.
6. A meat object cutting apparatus comprising:
a supporting frame;
a set of blades securely attached to said supporting frame, wherein the food object is placed on said blades;
a pusher head having a number of fingers, wherein one end of said pusher head being pivotally connected to one end of said supporting frame; and
a force generating means connecting to said pusher head,
wherein said fingers and said blades are shaped to fit said fingers into the spaces between said blades as the angle between said pusher head and said supporting frame decreases and whereby the meat object is sheared and cut by being pushed against and through said blades until said fingers pass through the spaces between said blades.
7. The meat object cutting apparatus according to claim 6, wherein said blades are of being serrate.
8. A meat object cutting apparatus comprising:
a supporting frame;
a set of blades securely attached to said supporting frame, wherein the food object is placed on said blades;
