Abstract: Sheets (26, 28, 30, 32) of aromatic polyamide polymer fibers are folded or formed into various shapes and constructions and used as light diffusers on lamps. The light diffusers are resistant to combustion which allows them to be placed closer to the light source. The diffusers are translucent and provide an appearance similar to parchment or rice paper.

Abstract: An elongated, planar support member is provided with dental floss about its peripheral edge. Multiple notches extending into the support member at various locations about the peripheral edge thereof expose multiple lengths of floss for flossing teeth. The lengths of floss extending across the notches are at various angles with respect to the longitudinal extent of the support member in order that the interdental spaces between various teeth are conveniently and effectively accessed.Preferably, four lengths of floss are exposed across four notches. Two floss lengths are parallel to a longitudinal axis of the support member and two floss lengths are at an angle to the longitudinal axis of the support member.The peripheral edge of the support member is provided with a groove. In one embodiment of the invention, the floss is fixed in the groove. In another embodiment, the floss is rotatingly positionable in the groove.
