all stated objects and to provide long life in a light-weight
product which will sustain even the worst loads. It is further
disclosed (col. 3, lines 21-28) that “[t]he injected tire
material is basically a tough variety of nylon, which may be
compounded with or more additional materials selected from the
group one including carbon black, elastomeric material, and glass
fiber; and we have obtained our highly satisfactory results using
a so-called super-tough nylon known as Zytel, ST-100 Series,
being a product of the DuPont Company, Wilmington, Delaware.”
From the disclosure of Thompson that the aircraft roller is
fabricated from nylon and metal, we find that the aircraft roller
meets the claimed “fabricated from a polymeric material,” since
the claim does not preclude fabrication from other materials in
addition to the polymeric material. From the disclosure that the
roller is for use in aircraft, that it is capable of sustaining
even the worst loads, and that the nylon used is a “super-tough
nylon” we find that Thompson’s disclosure is sufficient to
establish a prima facie case of anticipation of claim 1. Note
