Abstract: A multi-positionable arrangement of substantially parallel bars which form a substantial track for a ball and for disposing the track to a position accessible to the feet, legs, hands and arms of the body to be exercised. The bars are adjustably spaced apart to provide for adjustment of contact engagement with ball surface so that repeated stroking of the ball on the track path requires striking contact at a particular point on the ball surface and thereby exercise of some specific body muscles and reflexes.

Abstract: A safety guard device for a power tool discharge chute which includes a shaft attached to the chute and extending across the opening of the chute. There are a plurality of elongate spaced-apart blade elements mounted to the shaft for pivoting within the chute and one or more springs or other resilient elements are provided for biasing the blade elements into a closed condition within the chute to prevent operator access through the opening of the chute and permitting the blades to pivot into an open condition so that bulky material may be discharged through the chute.
