Abstract: A retaining clip for use with a variety of wire hooks and other forms of hangers used to store or display tools, merchandise, and other objects on perforated composition panel board commonly known as peg board. The retaining clip is formed of semi-elastic material and consists of a central portion grooved to fit over the shank of conventional peg board hooks, with two arms projecting outward on opposite sides of the central groove, each with barbed prongs positioned to be inserted into adjacent perforations in the peg board and to be locked or retained therein by the barbs, thus preventing movement of the hook and accidental detachment.

Abstract: A device for installation in the water supply pipe to a bath shower head comprising a venturi aspirator connected to a vented measuring chamber, said chamber connected to a supply container for liquid additive. Restricting the vent to the measuring chamber creates a pressure differential causing additive liquid to flow into said chamber. With the vent reopened, the liquid additive flows by gravity and differential pressure into the duct connected to the venturi aspirator, mixing the air and water flowing to the shower head and producing an aerated shower spray with liquid additive dispersed therein.
