## Abstract

A method and apparatus for handling and dispersing a coolant and/or working fluid in ophthalmic lens processing equipment and the like. The apparatus includes a dispersing member (50) including a landing surface (52). An extension strip (62) projects away from the landing surface and includes a leading edge (64) having a compound arcuate contour. In operation a columnar flowing fluid (60) is directed onto the landing surface where it is spread into a sheet of flowing fluid (80). The sheet of fluid is guided away from the landing zone and onto working members operably intended to receive the fluid.

## Claims

### Claim 1

A fluid dispersing apparatus operable for use in ophthalmic lens producing machines and the like, said fluid dispersing apparatus comprising:
a dispersing member having,
a landing surface operable to be positioned at
an angle with respect to a free flowing column of fluid, and
an extension strip extending away from said landing surfce in an intended direction of flow of the fluid at an obtuse angle with respect to said landing surface, said extension strip being fashioned with an arcuate front edge portion when viewed in a plan perspective, and being curved away from the intended direction of travel of the sheet of fluid away from said landing surface extension strip; and
means connected to said dispersing member for operably mounting said dispersing member upon a machine adjacent to a source of generally columnar flowing fluid.

### Claim 2 (depends on 1)

A fluid dispersing apparatus as defined in claim 1 wherein:
said landing surface being gently concave with respect to the direction of intended receipt of the columnar flowing stream of fluid.

### Claim 3 (depends on 1)

A fluid dispersing apparatus as defined in claim 1 wherein:
said extension strip being fashioned with an arcuate upward configuration when viewed in an edge perspective toward said landing surface.

### Claim 4 (depends on 1)

A fluid dispersing apparatus as defined in claim 1 and further comprising:
containment means extending away from said landing surface in a direction opposite to the intended direction of flow of the fluid.

### Claim 5 (depends on 4)

A fluid dispersing apparatus as defined in claim 4 wherein said containment means includes:
lip means extending generally parallel to but offset from an intended direction of flow of the columnar flowing stream of fluid and perpendicular to an intended direction of flow of the sheet of fluid directed away from said landing surface.
