Abstract: A pneumatic tire comprises a ground contacting tread including a tread strip extending axially between tread edges and sidewalls extending radially inwardly from each tread edge to respective bead regions, the tread being reinforced by at least a first circumferentially extending breaker ply, characterized in that each sidewall is reinforced by a carcass half ply extending from a radially inward first edge in the bead region to a radially outward second edge in the tread axially between the center and adjacent edge of the breaker ply; the carcass half ply including one or more reinforcing elements wound continuously between the radially inner and outer edges of the carcass half ply and around the circumferential periphery of the tire.

Abstract: A disposable biopsy forceps includes an elongate tubular member having proximal and distal ends. Manually operated actuating means is mounted to the proximal end of the flexible tubular member. A biopsy jaw assembly is mounted to the distal end of the tubular member and is operatively connected to the actuating means by a control wire extending through the tubular member.

Abstract: A permanent magnetic top is arranged to rotate on one or more surfaces, of a toy induction turret, which are in close proximity to a coil. An electric circuit is arranged to switch the coil in such a manner so as to accelerate the top. A handle is connected to the turret so that the top may be skillfully transferred from one surface to another. In one version it is arranged to generate a tone or musical notes when the top is spinning.

Abstract: Curved airfoils are mounted on members attached to a vertical shaft. The ends of the airfoils point outward from the shaft. The members are attached to the upper and lower sections of the airfoils and converge as they approach the shaft. This minimizes the shaft length above the turbines upper most bearing and provides a balanced condition that distributes forces in such a manner which reduces airfoil stress.

Abstract: A new variety of Amelanchier laevis is disclosed which is particularly characterized by its trait of achieving maximum floral display prior to the unfolding of its leaves so as to maximize the color display during the blossom period.

Abstract: A new variety of Amelanchier canadensis is disclosed which is characterized by its large flowers, averaging 2 centimeters in size, which give rise to full form, densely packed, large, sweet fruit, up to 1/2 inch in size which are thus large, plentiful, and easily harvested.

Abstract: A new variety of Amelanchier grandiflora is disclosed which is characterized by its unique yellow flower buds unfold into white flowers, its wide-spread branches, and, most particularly, by a brilliant red fall foliage display.
