Abstract: An insert for a shoe or a shoe interior comprises a central portion which prevents excess pronation, a front portion which extends arcuately and transversely across the foot to support the transverse metatarsal arch, a rear portion which extends transversely across the foot and contacts the forward edge of the heel, a lateral, slanted edge which is aligned parallel to the longitudinal axis of the arch and support the fifth metatarsal shaft of the foot, and a fourth portion which slopes medially. The device is designed to fit the area of void on the plantar side of the human foot to support the structure of the foot to prevent excess pronation and to substantially reduce foot morbidity.

Abstract: A band saw drive arrangement including relatively large driven and idler pulleys and a relatively small drive pulley. The pulleys are all V-grooved pulleys and are mounted in coplanar relationship for rotation about spaced, parallel axes, with the drive pulley positioned between the driven and idler pulleys. The drive pulley is motor driven and an endless flexible V-belt is trained about the drive and driven pulleys. A V-belt is also secured in the groove of the idler pulley. An endless flexible saw band is trained about the driven and idler pulleys with its inner surface in frictional driving engagement with the outer surfaces of the V-belts.
