Methods for making differentially pattern cured microstructured articles are disclosed, using a molding tool having a microstructured surface, a patterned irradiation to generate irradiate and non-irradiated regions in a radiation curable resin. Different combinations of molding tools and patterned irradiation provide numerous variants of differentially pattern cured microstructured articles without requiring costly modification of the molding tools.

Methods for making differentially pattern cured microstructured articles

A system for processing vapor. The system includes a vapor source for producing a vapor and an outlet conduit coupled to the vapor source for carrying the vapor from the vapor source. Downstream of the vapor source the outlet conduit separates into a vapor bypass conduit and a vapor feed conduit. The system further includes a first vapor control valve disposed in the bypass conduit, a second vapor control valve disposed in the feed conduit, a first vacuum chamber connected to the bypass conduit, and a second vacuum chamber connected to the feed conduit.

The invention includes a method for collecting radiation. An electromechanical radiation collection device is disposed in a roll to collect radiation directed at the roll. The invention is also an apparatus comprising a roll having an outer surface. An electromechanical radiation collection device is disposed in the roll.

The invention is a pneumatically actuated energy collection device. The device includes a support which has an energy collector thereon. A shutter is slidably attached to the support and can be moved between a first &ldquo;closed&rdquo; position and a second &ldquo;open&rdquo; position. In its first position, the shutter covers the collector and in its second position, the shutter uncovers the collector. The shutter is biased into one of the positions. A chamber is disposed adjacent to the shutter so that when the chamber is pressurized, the shutter bias is overcome and the shutter is moved between the first position and the second position.
