Title: Squirrel-proof bird feeder device
Inventor: SUNATORI GO SIMON
IPC: A01K39/01
Filed: 1997-01-29
Abstract: A free-standing bird feeder device comprises a generally cylindrical food container, a substantially circular feeding platform supported by a post, and a substantially spherical or ellipsoidal squirrel guard to prevent a squirrel or like ground animal from gaining access to the seed or other food on the feeding platform.  The squirrel guard may be made of either a rigid material, or a flexible material to be inflated with air or foam.  The spherical or ellipsoidal shape of the bird feeder provides aerodynamic characteristics, causing the air from the wind to form a laminar flow instead of a turbulent flow.  This invention relates to bird feeders, more particularly to a bird feeder having a squirrel guard.

Title: Acetabular implant with threaded liner and locking ring
Inventor: ROHR WILLIAM L JR
IPC: A61F2/34
Filed: 1997-08-26
Abstract: The acetabular implant of the invention includes a shell having a threaded polarhole with a liner having a threaded polar protrusion extending therefrom for threadable accommodation within the threaded polar hole. Further, the implant includes a locking ring carried by the shell for engagement with the liner. In use, the liner is screwed into the shell by the cooperating threads of the liner and shell. As the liner bottoms out in the shell, the locking ring slides into an annular groove formed in the outer periphery of the shell to lock the liner to the shell. The locking engagement of the locking ring prevents the liner from shifting laterally relative to the shell which therefore prevents the liner from rotating in a direction to loosen the shell relative to the liner. While it is preferred that the liner is formed from a metal, the liner may be formed from either a metal or a plastic dependant upon the clinical requirements for the patient.
