Abstract: CANADIAN PATENT APPLICATION                      OF       MIHKEL MATHIESEN AND OLLE NYSTR?M                      FOR     A COMPOSITION AND A METHOD OF CAPTURING SULPHUR     Abstract of the Disclosure:      The invention relates to a composition and a method of capturing sulphur emanating from burning carbona-ceous fuel particles of an aqueous fuel composition which comprises about 60-80% by weight of carbonaceous fuel particles with an ash content of below about 5% by weight on a dry basis, about 0.05-2.0% by weight of a flow-enhancing chemical which includes a non-ionic dispersant, and a liquid carrier phase consisting es-sentially of water. The sulphur is captured prior to formation of gaseous sulphur oxides which become diluted 1a on the gaseous phase during and after combustion, and involves the introduction of a sulphur captor which preferably is chosen from hydroxides, oxides or carbo-nates of calcium or magnesium on or in reaction-facili-tating proximity to the burning carbonaceous fuel par-ticles, thereby utilizing local chemical potential in the formation of locally or relatively stable sulphides at relatively low oxygen potentials, the sulphur being captured during the combustion phase as solid sulphide and subsequently, when the temperature drops as the solid combustion residue leaves the flame and the local oxygen potential rises, and sulphate formation occurs, as the sulphate. The amount of sulphur in the combus-tion off gas is accordingly greatly reduced according to the method of the present invention. 1b

Abstract: ARITHMETIC UNIT FOR USE IN   DATA PROCESSING SYSTEMS                         Abstract of the Invention A data processing system using unique procedures for handling var-ious arithmetic operations.  Thus, in floating point arithmetic mantissa cal-culations the system uses a novel technique for inserting a round bit into the appropriate bit of the floating point result wherein a look-ahead carry bit generator stage is used for such purpose to reduce the overall mantissa calculation time.  Further, the system utilizes unique logic which operates in parallel with the floating point exponent calculation logic for effect-ively predicting whether or not an overflow or underflow condition will be present in the final exponent result and for informing the system which such conditions have occurred.  Moreover, the system utilizes a simplified tech-nique for computing the extension bits which are required in multiply and divide computations wherein a programmable array logic unit and a four-bit adder unit are combined for such purposes.

Abstract: POSITIVE TEMPERATURE COEFFICIENT        THERMISTOR DEVICE           ABSTRACT OF THE DISCLOSURE      The PTC thermistor device according to the present invention is constructed as follows.    The heat generated in the PTC thermistor body is conducted at a high efficiency through the filling material to the ceramic case having an excellent heat resistance, and thus the heat resisting characteristic is excellent.    The ceramic material which constitutes the case has a thermal expansion coefficient which is virtually the same as that of the PTC thermistor element.  Since the filling material fills the clearance between the ceramic case and the PTC thermistor body, the stability against temperature change and thermal stress is therefore high.          The PTC thermistor body is completely shielded from the ambient atmosphere by the filling material.
