Abstract: One example provides a golf disc retainer for use with a storage container, the golf disc retainer including a body extending longitudinally between opposing first and second ends and laterally between opposing first and second sides, the body comprising an elastic material and including a central base portion extending between the first and second ends, and a pair of opposing side rails extending between the first and second ends along opposing longitudinal sides of the central base portion. Upper surfaces of the central base portion and the pair of opposing side rails together define a wedge-shaped space extending between the first and second ends, the wedge-shaped space to receive golf discs positioned vertically to the upper surfaces and perpendicularly to the opposing side rails with the elastic material of the upper surfaces of the central base portion and the opposing side rails to engage and conform about respective arc segments along a circumferential rim of each golf disc.

Abstract: Disclosed is an air volume control for use with a flowing water line to control the quantity of air sucked by venturi action into the water line. The air volume control comprises a tubular valve body with a common member defining co-axial oppositely directed valve seats, one seat of which is automatically closed by a float valve in the event of reverse flow of water or back pressure of air into the valve body and the other seat of which is closed by a control valve when a regulator knob is rotated clockwise to the "off" position. In rotating the regulator knob counterclockwise to its "on" position, a cross pin follower of the regulator knob engaged with cam surfaces of the control valve unseats the control valve from its valve seat. Air is sucked into the water line through air entry ports in the valve body that are upstream of the control valve and float valve. Closing of either the control valve or float valve close off such air being sucked downstream past the valve seats into the flowing water line.
