1. An automated method of administering a single investment company comprises:
(a) the single investment company issuing one or more classes of shares that are bought from and redeemed with the single investment company at a net asset value;
(b) the single investment company issuing one or more classes of shares that are listed for trading on a securities exchange and that are bought and sold at negotiated market prices; and
(c) maintaining in one or more computers, account data of the outstanding shares, wherein an owner of any share of any share class has an undivided interest in the single investment company.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A lighting fixture having both a transmitted and reflected component comprising:
a polymeric material;
said polymeric material having a white characteristic for selectively providing variable transmission and reflection properties and for providing a selected diffuse transmission component of a total fixture output.
2. A lighting fixture as recited in claim 1 wherein said white characteristic is created by a foamed polymeric material and said polymeric material provides a set diffuse transmission component of greater than 1% and less than 99%.
3. A lighting fixture as recited in claim 2 wherein said polymeric material is foamed using a gas.
4. A lighting fixture as recited in claim 3 wherein said gas is a selected one of nitrogen and carbon dioxide.
5. A lighting fixture as recited in claim 2 wherein said polymeric material is foamed using a chemical blowingfoaming agent.
6. A lighting fixture as recited in claim 5 wherein said chemical blowingfoaming agent comprises sodium bicarbonate and citric acid.
7. A lighting fixture as recited in claim 1 wherein said polymeric material is formed by pigmenting a transparent material with a white pigment and said polymeric material provides a set diffuse transmission component of greater than 1% and less than 25%.
8. A lighting fixture as recited in claim 7 wherein said white pigment is one of barium sulfate or titanium dioxide.
9. A lighting fixture as recited in claim 7 wherein said white pigment is greater than or equal to 1%.
10. A lighting fixture as recited in claim 7 wherein said transparent material is an acrylic.
11. A lighting fixture as recited in claim 1 wherein said polymeric material is formed by blending transparent materials having different refractive indices and said polymeric material provides a set diffuse transmission component of greater than 1% and less than 99%.
12. A lighting fixture as recited in claim 11 wherein said transparent materials having different refractive indices include an acrylic and a polycarbonate.
13. A lighting fixture as recited in claim 1 wherein said polymeric material is formed by an expanded bead material and said polymeric material provides a set diffuse transmission component of greater than 1% and less than 99%.
14. A lighting fixture as recited in claim 13 wherein said expanded bead material includes an expanded acrylic material and an expanded polymethyl methacrylate (ePMMA).
15. A lighting fixture as recited in claim 1 wherein said polymeric material is formed by adding a filler to a material selected from the group including polycarbonate, polystyrene and acrylic and said polymeric material provides a set diffuse transmission component of greater than 1% and less than 99%.
16. A lighting fixture as recited in claim 15 wherein said filler includes one of glass fibers, glass micro-spheres and reflective flakes.
17. A lighting fixture as recited in claim 1 wherein said polymeric material is formed with a selected, varied wall thickness for each predefined section of an optical component.
18. A lighting fixture having both a transmitted and reflected light component comprising:
an optical member formed of a polymeric material;
said polymeric material having a white characteristic for selectively providing variable transmission and reflection properties and for providing a selected diffuse transmission component of a total fixture output.
