Abstract: The present invention provides a process for the continuous production of chlorine dioxide by the reaction of hydrochloric acid with an alkali metal chlorate solution, which is obtained by means of an electrolysis plant from a chlorate solution containing alkali metal chloride circulating in the process, together with cathodically-formed hydrogen, in a cascade reactor with the introduction of air, wherein the reaction of the alkali metal chlorate solution with the hydrochloric acid is carried out under reduced pressure and chlorine gas separated off from the reaction product is reacted with the cathodically-formed hydrogen with the introduction of external chlorine gas to give the required amount of hydrochloric acid. The present invention also provides a device for carrying out this process, comprising at least one chlorate electrolysis plant, a cascade reactor, a separation column and a hydrochloric acid synthesis furnace, which are connected with one another by means of pipes according to the manner of operating the process, wherein a valve is provided in the air inlet pipe of the reactor, which valve is regulated corresponding to the pressure at the product outlet of the reactor.

Abstract: A distributed sensor system including an optical source (100) having a short coherence length for optionally continuously monitoring each sensor in the system. In one preferred embodiment, an array of fiber-optic sensors (110) are organized in a ladder configuration, with the sensors positioned in spaced relation and defining the rungs of the ladder. Light transmitted through the sensors is multiplexed onto a return arm (114) of the ladder, with sensor spacing being such that interference between light from different sensors is prevented. The multiplexed signals are received by an optical fiber receiver (118, 120) which couples the mutiplexed light with an interfering optical reference signal to produce a phase difference signal representing conditions influencing selected sensors. Embodiments are disclosed for use of either pulsed or continuous wave light sources. In another preferred embodiment, the sensors comprise a plurality of interferometers (404,406) connected in series configuration by a common optical fiber (402), which provides multiplexed output signals from the sensors to another plurality of interferometers (418, 420) comprising receivers. Functional equivalents of the series configuration provide sensors and receivers comprising birefringent or two-mode fiber. The optical path length differences between each pair of sensor arms (409, 410, 411 and 412) are selected to prevent interference between the multiplexed sensor output signals from the various sensors. The optical path lengths through the sensors (404, 406) and receivers (418, 420) are structured so that each receiver (418, 420) produces a phase difference signal relating to conditions affecting light transmission through a specific sensor (404, 406). A phase and amplitude modulation technique is disclosed for providing heterodyned output signals from the dristributed sensor system.

Abstract: A metal matrix composite is formed by contacting a molten matrix alloy (18) with a permeable mass of filler material or preform (16) in the presence of an infiltrating atmosphere. Under these conditions, the molten matrix alloy (18) will spontaneously infiltrate the permeable mass of filler material of preform (16) under normal atmospheric pressures. Once a desired amount of spontaneous infiltration has been achieved, or during the spontaneous infiltration step,the matrix metal which has infiltrated the permeable mass of filler material or preform (16) is directionally solidified. This technique allows the production of spontaneously infiltrated metal matrix composites having improved microstructures and properties.
