Abstract: An orthopaedic knee prosthesis includes a tibial insert and a femoral component configured to articulate on the tibial insert. The tibial insert includes a lateral articular surface and medial articular surface that is asymmetrically shaped relative to the lateral articular surface. The medial articular surface is shaped to reduce anterior translation of a medial condyle of the femoral component, while the lateral articular surface is shaped to allow a lateral condyle of the femoral component to pivot, relative to the medial articular surface, along an arcuate articular path. Additionally, one or both condyles of the femoral component may include a femoral articular surface having a curved femoral surface section defined by a continuously decreasing radius of curvature.

Abstract: A motorized treadmill that provides more fluid rotational motion of the treadmill belt, increases the life of the motor, provides more stable and reliable elevation of the treadmill, and provides automatic dampening for users of all weight ranges. The treadmill includes an external frame having first and second longitudinal side rails and at least one frame cross-bar extending therebetween, and an upright frame section that extends upwardly from a first end of the longitudinal side rails. First and second rollers are rotatably mounted on the external frame and positioned so as to be substantially perpendicular to the longitudinal side rails. The first roller is coincident with a first axis. A deck is mounted on the external frame and positioned between the first and second rollers and the longitudinal side rails. An endless belt is mounted around and extends between the first and second rollers for rotation therewith.

Abstract: A removable sole plate cover for fabric pressing irons is formed of a thin, flat, planar sheet (approximately fifteen thousandths of an inch) of polytetrafluoroethylene (PTFE) material (e.g., Teflon, tm). The sheet is removably securable to the sole plate of a hand operated iron, and protects fabrics being pressed from burning, scorching, and polishing by reducing friction between the iron and the fabric and also providing for more even heat distribution from the sole plate to the article being pressed. The cover is removably secured to the iron by forward and rearward lateral flaps. The forward flaps each have an extension ear extending therefrom, which are folded to overlap one another and to secure to the corresponding forward flap of the opposite side. The rearward flaps each have at least one eyelet therein, and are folded upwardly along the edge of the iron sole plate and secured across the iron by one or more tensile springs.

Abstract: A spring clip mounts a mounting tube thereon, wherein the mounting tube receives a tissue roller rotatably thereabout, and the mounting tube having a cap removably mounted therefrom, with the cap coaxially aligned with the mounting tube, including projections fixedly mounted to the cap to extend over the tissue roll to secure the tissue roll between the cap and the spring clip structure.

Abstract: A visual guide for sharpening chain saw teeth. Magnetic material is affixed to one leg of an elongated member having an L-shaped cross section. The magnetic material is affixed to the external portion of the leg such that when the device is magnetically attached to a chain saw blade, the other leg of the device will extend away from and parallel to the chain saw blade. Markings are formed on the upward-facing portion of the second leg indicating the correct angle for applying a circular file to the cutting edge of the chain saw tooth. Notches are formed on the device for use as a template in gauging the proper shape of the chain saw tooth being filed.
