Abstract: AN IMPROVED PROCESS FOR THE MANUFACTURE OF POTASSIUM NITRATE          CO-PRODUCTION OF HYDROCHLORIC ACID                 ABSTRACT OF THE DISCLOSURE        The present invention relates to a process for the manufacture of potassium nitrate with co-production of relatively concentrated aqueous solution of hydrochloric acid.          According to the invention, potassium chloride and nitric acid are reacted in the medium of an organic solvent selected from butanols and pentanols.  The solution obtained after the separation of the resulting potassium nitrate, containing hydrochloric acid together with nitric acid and said organic solvent, is subsequently washed thus resulting an aqueous solution of hydrochloric acid which contains nitric acid.  The nitric acid is extracted by an organic solvent selected from organic esters of phosphoric acid, ketones having five to ten carbon atoms and straight or cyclic polyethers having molecular weight in the range of 100 to 1000 and polyalkylene glycols which are slightly miscible in water and having molecular weight in the range of 1000 to 3000, or mixtures thereof, preferably in the presence of an organic diluent.  The remaining brine consists of a substantially nitrate-free hydrochloric acid.  The NO? - loaded solvent is washed, the nitric acid as well as the organic solvent being respectively recycled in the process.          The process saves appreciable amounts of nitric acid, co-producing hydrochloric acid which can be utilized without any further concentrating step.

Abstract: ABSTRACT     A reflecting optical dosimeter is described in which there is provided a thin block of optical material.  The block has at least a first pair of parallel edges and preferably a second pair perpendicular thereto, and includes an input light pipe at a small angle from the perpendicular to one edge of said pair.  Output light path means are also provided, so that light entering via the input pipe is reflected several times between at least said pair of edges,  before exiting via the output light path means.  The optical material of the block becomes darker in response to given radiation, so that the decreased transmission of light along the path from the input pipe to the output light path means is a measure of the dose of said given radiation.  More preferably, one corner of said block is cut at  substantially 45° to form a small fifth edge.  All five edges are coated to be reflective except at said light pipes.  Light is reflected from the fifth edge and then back and forth between the second pair of edges before exiting.  Most preferably the optical material is a halide crystal, and the block is one unit thick, N units between the edges of said pair and M plus one half units between the edges of the second pair, while the fifth edge is the square root of two units in length, with the output light pipe being at least one and one half units long.

Abstract: Abstract of the Disclosure A pattern matching device for calculating an overall similarity measure between a first and a second pattern represented by a first and a second sequence of feature vectors is described.  The device comprises a first circuit for calculating an elementary similarity measure between each feature vector of the first sequence and each feature vector of the second sequence, and a second circuit for iteratively calculating a recurrence formula which defines a recurrence value by a sum of each elementary similarity measure and an extremum of a prescribed number of previously calculated recurrence values.  The recurrence formula eventually gives an overall similarity measure between the two patterns. The elementary similarity measure is calculated by calculating a primitive similarity measure using a conventional circuit and subtracting a predetermined value therefrom using a compensation circuit.  Preferably, the second circuit for iteratively calculating the recurrence formula comprises circuitry for preventing the sum from overflowing outwardly of a preselected range.
