Abstract:
A pavement marker having improved daytime visibility comprises a transparent fluorescent top portion having a top surface and a front edge. Light received by the top surface of the top portion results in light being directed internally through the top portion and emitted from the front edge, thereby providing a daytime signal to drivers of oncoming vehicles. In an alternative embodiment, the top portion can comprise a polymer having in its backbone moieties that either absorb U. V. light or that are capable of undergoing rearrangement to moieties that absorb U. V. light, to provide greater fluorescent durability. The polymer can be present either within the fluorescent top portion or as a U. V. light screening layer on top of the top portion.

Abstract:
A pavement marker having improved daytime visibility comprises a transparent fluorescent top portion having smooth flat parallel top and bottom surfaces with a front edge therebetween and air interfacing most of the bottom surface. Light received by the smooth flat top surface of the top portion is directed internally through the top portion and emitted from the front edge, to provide a visible signal to drivers of oncoming vehicles.

Abstract:
A process and apparatus for embossing thermoplastic products having precise microstructured surfaces including using a continuous press having upper and lower belts with the embossing pattern(s); feeding thermoplastic material through the press where heat and pressure are applied to form the embossed pressure microstructure, and cooling the embossed material, all while maintaining pressure. A continuous embossing tool is provided by welding segments together, the welds including interface material at the weld joint which is of a different material than the segment material to increase the tensile strength.
Apparatus And Method For Manufacturing Microneedles
The apparatus comprises a mold assembly including at least one bore therethrough having a cavity therein defining the shape of the finished microneedle shape to be formed therein. The bore has an inlet opening and an exit opening. The apparatus also comprises means for locating the polymer to be formed at one end of the cavity and means for introducing fluid into the inlet opening of said bore and into the cavity. The apparatus also comprises exhaust means communicating with the exit opening of the bore, so that introducing the fluid through the polymer causes the polymer to assume the shape of the cavity and the fluid forms a hollow channel to define a needle-like structure in the polymer as the fluid is exhausted through the cavity and the bore.
Process And Apparatus For Fabricating Precise Microstructures And Polymeric Molds For Making Same
There is disclosed a method and apparatus for producing a polymeric film that accurately replicates a complex mold surface at least a portion of which surface has microstructured or nano-structured dimensions. A polymeric powder is electrodeposited on an underlying mold surface. Then the powder is cured to create a polymeric film. Finally the film is removed from the mold surface.
There is disclosed a method and apparatus for producing a polymeric film that accurately replicates a mold surface at least a portion of which surface has a complex pattern of microstructured or nano-structured dimensions. A polymeric powder is electrodeposited on an underlying mold surface and heated to its molten state to replicate a pattern on the mold surface. Then the powder can be cured to create a polymeric film. Finally the film is removed from the mold surface.

Method And Apparatus For Embossing A Precision Pattern Of Micro-Prismatic Elements In A Resinous Sheet Or Laminate
An improved method and apparatus is provided for continuously embossing a precision pattern of micro-prismatic elements on a surface of a resinous sheeting material with the aid of an endless metal embossing belt. The method includes the steps of moving the belt along a closed path through a heating station and a cooling station, conveying superimposed resinous film and sheeting material into proximity with the belt, passing the film and sheeting between the belt and a series of sonic welding heads to thereby begin to impress a pattern of micro-prismatic formations of the belt into one surface of the sheeting, pressing the film and sheeting against the heated belt until the one surface of the sheeting fully conforms to the embossing pattern, and stripping the film and embossed sheeting from the belt.
