Abstract: Basketball apparatus that includes a support member, a backboard mounted on the support member, and a hoop mounted on the backboard. The backboard is mounted on the support member for rotation with respect thereto, wherein the backboard is locatable in selected angular positions with respect to a predetermined location that is disposed remote from the support member and the backboard mounted thereon.A detecting device is mounted at the location remote from the support member for detecting the number of shots taken by a player and is also responsive to a device for indicating successful shots to the hoop, wherein the proficiency of a player in shooting the ball through the hoop is accurately calculated and recorded.

Abstract: A signature folder is disclosed in which a vacuum system is provided to prevent tail whipping of the signature when the direction of movement thereof is reversed. The folder provides two counter-rotating cylinders. A portion of the signature moves along the periphery of one cylinder and then reverses direction to move onto the periphery of the other cylinder. A vacuum system is provided adjacent to the signature when it reverses direction. The vacuum system includes a pair of guides and a central, freely rotatable vacuum roll. The vacuum causes the reversing portion of the signature to move into engagement with the guides and roll and eliminates tail whipping. Further, it guides the signature so that it smoothly moves onto the periphery of the subsequent roll.
