A method for laying down a nanoweb of nanofibers from a centrifugal spinning process by a combination of an air flow field and a charging arrangement. Fibrous streams in the form of fibrils of molten polymer or polymer solution are discharged from a rotating member into an air flow field that is essentially parallel to the direction of discharge of fibrils at the point of discharge of the fibrils. The fibrous streams are attentuated and directed by means of the air flow field onto the surface of a collector to form a nanoweb. The fibrous streams are charged along all or at least a portion of their route from the point of discharge to the surface of the collector.

A method and apparatus for preparing a relief printing form from a photosensitive element that includes a photopolymerizable composition layer having an exterior surface and capable of being partially liquefied. The method includes the steps of (a) heating the exterior surface of the photopolymerizable composition layer to a temperature sufficient to cause a portion of the layer to liquefy, forming the liquefied material; and (b) removing the liquefied material; wherein the heating step is performed using vibrationally-induced frictional energy.

A process for the faster manufacturing of hydrocarbon, fluorocarbon and chlorocarbon acyl peroxides is disclosed wherein a hydroxide, a peroxide and an acyl halide are reacted under continuous vigorous agitation conditions so as to bring the reaction to substantial completion is less than one minute.

Process for preparing peroxides

Apparatus which can be used for producing negative ions in a gaseous or liquid fluid is disclosed, as well as methods of using the apparatus to determine electron attachment parameters, to identify species in the fluid, or to separate selected species from the fluid. The apparatus comprises a photoelectron emitter, including a UV light source, which can be operated in pulsed or continuous modes, and a photocathode; in addition, a radially-spaced, coaxial negative ion collector, including a negative ion receiving plate, at least one of the photocathode and the receiving plate having cylindrical configuration.
