Abstract: A method of fabricating a hollow-core photonic-bandgap fiber, comprising the steps of: providing a stack of capillaries, wherein the stack has a hollow core and the capillaries at a boundary of the core comprise a plurality of first, corner core capillaries and a plurality of second, intermediate core capillaries; applying a pressure differential between the corner core capillaries and the intermediate core capillaries, whereby a size of the corner core capillaries can be controlled in relation to the intermediate core capillaries; and reducing the stack to a fiber, wherein the fiber has a hollow core and a cladding which surrounds the core at a core boundary and comprises a lattice or network of struts and interstitial nodes which together define an array of cavities.

Abstract: Methods and systems are disclosed for analyzing and treating a fluid containing a peroxyacid and/or peroxide. A method of analyzing the fluid includes introducing into the fluid a decomposition agent that catalyzes decomposition of the peroxyacid and/or peroxide into decomposition products including oxygen, then directly or indirectly measuring an amount of oxygen produced after introduction of the decomposition agent, and determining an amount of the peroxyacid and/or peroxide present in the fluid. The amount of peroxyacid and/or peroxide in the fluid can also be monitored and controlled by further adjusting the amount of the peroxyacid and/or peroxide in the fluid based on the determined amount thereof. A system for performing the methods includes a decomposition agent infusion device for introducing the decomposition agent into a fluid sample, and a sensor for directly or indirectly measuring an amount of oxygen produced after introduction of the decomposition agent.

Abstract: Equipment for forming a tubular rod of fibrous material comprises: a gathering station constructed to receive a continuous supply of fibres and to gather the fibres into a bundle as the fibres advance through the equipment; a divider arranged in the path of the fibres through the equipment and constructed to from a cleft along the length of the bundle as it advances through the equipment; a mandrel positioned in the path of the bundle of fibres in alignment with the divider and constructed to form the cleft into a passage through the bundle of fibres as the bundle of fibres advances over the mandrel; and a die constructed and arranged to cooperate with the mandrel to form the fibres in a tubular configuration around the mandrel.
