Abstract: An arm, wrist, shoulder and chest exerciser which allows maximum movement for those areas being exercised. A hand-held tube has an inner, rotatable axle. This axle attaches to another tubular structure at the top of the hand-held tube and allows this structure to rotate with a repetitive movement of the hand or arm.

Abstract: A hollow inner hoop receives a fluent material through a filler valve and fits within a curved inward facing depression in an outer hoop. The outer hoop has a slot in its outer surface; a stick with guiding wings at a proximal end fits within the slot and is turned to align the guiding wings within an axial direction of the hoops.

Abstract: An air cushion shoe base has a sole and a vertical rim within which is filled in air tight relation with foam rubber which is tightly covered by an insole. The foam rubber forms small metering orifices for restricting and delaying fluid flowing forward and rearward in response to weight shifts of a foot. A valve is provided within the rim, and the valve has a central body with a long valve orifice and lateral extensions for joining the body to an inside of the rim. The shoe base is filled to a desired pressure which is maintained periodically through the valve. A T-shaped welt extends around an upper peripheral area of the rim and insole for joining the cushion base to a shoe upper.

Abstract: An air cushion shoe base has a thick sole and a thick vertical rim across which are formed air tight partitions and an insole. Each partition has a small valving orifice for flowing fluid between sections on opposite sides of a partition. A valve is provided within the rim, and the valve has a central body with a long valve orifice and lateral extensions for joining the body to an inside of the rim. A T-shaped welt extends around an upper peripheral area of the rim and insole for joining the cushion base to a shoe upper.

Abstract: A container has one or more openings which extend into the container down elongated passageways. The passageways have needle prodders mounted along sidewalls to discourage rodent retreat once a rodent has entered the passageway. The interior ends of the passageways have doors with small holes for permitting rodents to smell enticing substances on the interior of the container, which doors are structured with lengths greater than the height of the passageways such that the doors extend into the interior of the container at an angle and can only be opened into the interior. The doors have needles on interior sides to keep rodents captured therein away from said doors. Sidewalls of the passageways extend into the interior of the container for keeping captured rodents away from side edges of the doors when in any open position.
