The mark consists of a semi-circle positioned beneath a cylindrically-shaped object. The right end of the object is rounded, and the left end of the object is flat. A bottom edge of the object is contoured to run, from right to left, along a perimeter of the semi-circle from a center of the semi-circle with a space between the object and the semi-circle. A top edge of the object is flat. The outline of the object and semi-circle is suggestive of the letter "R".
Color is not claimed as a feature of the mark.
