Abstract:
A method is provided for making a photonic band gap fiber including the steps of etching a preform and then drawing the preform into a photonic band gap fiber. Glass tubes are bundled and then formed into a photonic crystal perform having a number of passageways by reducing the cross-section of the bundle. One of the passageways is enlarged by flowing an etchant through it. After cleaning, the band gap fiber is made from the etched photonic preform, for example, by drawing.
Abstract:
A method of converting biological material into energy resources includes transmitting biological material to a pulsed electric field (PEF) station, and applying a PEF to the biological material within a treatment zone in the PEF station to generate treated biological material. The method also includes transmitting the treated biological material to a biogenerator, and processing the treated biological material in the biogenerator to produce an energy resource. A converter may carry out this process, and may include the PEF station and the biogenerator.
Abstract:
A method of supporting denitrification includes receiving biological material at a pulsed electric field station and applying a pulsed electric field to the biological material within a treatment zone in the pulse electric field station to generate treated biological material. The method also includes transporting at least a portion of the treated biological material to an anoxic bioreactor in substitution, at least in part, for an external source of electron donor. A system for supporting denitrification is also provided.

Abstract:
Disclosed is a method of making a photonic crystal preform which provides improved properties of the photonic band-gap crystal waveguide fiber drawn therefrom. The photonic crystal preform defect is formed using materials having a particular shape or composition so that the defect walls are preferentially etched away to provide a photonic band-gap crystal waveguide fiber having a smooth walled defect.
Abstract:
A locking assembly for locking a multi-sided nut-like member in a desired communicating relationship with a valve body. The locking assembly includes a lock plate having a planar body portion with a locking opening defined by a plurality of sides oriented relative to each other in a closed, star-like configuration. The locking opening is adapted to be closely received over and communicate with the sides of an associated nut-like member. The body portion also includes an arcuate mounting slot spaced from the locking opening and which is adapted to receive a lock plate mounting fastener therethrough. A continuous side wall or skirt portion depends from the periphery of the body portion and serves to space the body portion from the surface of an associated valve body. Preferably, a lock plate adapter is also provided. The adapter includes a body member having a through opening which is received over a section of the associated nut-like member, and a securing member cooperable with the lock plate mounting slot. The lock plate adapter also includes a mounting portion adapted for disposition in contacting relation with the associated valve body.
