Title: Method and system for purifying exhaust gas
Inventor: KOBAYASHI YOSHIO
IPC: B01D53/50
Filed: 1985-07-25
Granted: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE According to the dry method of the invention for purifying an exhaust gas, fine particles of a Ca-type absorbent such as dolomite are sprayed into the exhaust gas, and the absorbent particles absorbing acid harmful substances from the gas are collected by a dust collector     along with other particles in the exhaust gas.  The collected particles are divided by a classifier     into a portion of coarse particles chiefly containing fly ash and a portion of absorbent particles not larger than a predetermined  size, and the latter portion only is supplied to a hydration reactor.      The absorbent particles in the reactor     are hydrated with superheated water vapor and thereby expanded, whereby an inactive shell formed on the surface of each particle by the absorption of the acid harmful substances is broken to reactivate the particles.  The reactivated absorbent particles are supplied to the exhaust gas again.          The acid harmful substances are therefore removable efficiently with a smaller amount of absorbent.

The substrate may be formed from a plurality of discrete elements defining interstices.  A matrix is disposed on the substrate without any chemical bond to the substrate.  The matrix has a second coefficient of thermal expansion different from the first coefficient of thermal expansion and is free to move relative to the substrate with changes in temperature.  The matrix may constitute a non-stoichiometric compound formed from a metal and a material providing negatively charged ions.  The excess from the stoichiometric ratio in the amount of the metal or the material providing the negatively charged ion controls the properties of the matrix.  The relative amount of the excess of the metal or the material providing the negatively charged ions from the stoichiometric ratio may be varied at different thicknesses of the matrix to vary the properties of the matrix at the different thicknesses.  The matrix may have microscopic cracks in its periphery.  A porous impervious to oxygen coating may be disposed on the matrix and may be provided with substantially the second coefficient of thermal expansion.  The coating covers the microscopic cracks and is instrumental in preventing the matrix from oxidizing.  A porous coating impervious to oxygen may also be disposed between the substrate and the matrix and may be provided with substantially the second coefficient of thermal expansion.  This coating prevents the substrate from oxidizing.  The different coatings or layers may be formed by a continuous process or by cyclic or pulsing techniques.

Title: Frequency modulation ballast circuit
Inventor: ZEILER KENNETH T
IPC: H05B41/295
Filed: 1987-02-17
Granted: 1993-06-29
Abstract: FREQUENCY MODULATION BALLAST CIRCUIT          ABSTRACT OF THE DISCLOSURE     A ballast circuit is provided for the start-up and operation of gaseous discharge lamps.  A power transformer connected to an inductive/capacitive tank circuit drives the lamps from its secondary windings.  An oscillator circuit generates a frequency modulated square wave output signal to vary the frequency of the power supplied to the tank circuit.  A photodetector feedback circuit senses the light output of the lamps and regulates the frequency of the oscillator output signal.  The feedback circuit also may provide input from a remote sensor or from an external computer controller.  The feedback and oscillator circuits produce a high-frequency signal for lamp start-up and a lower, variable frequency signal for operating the lamps over a range of light intensity.  The tank circuit is tuned to provide a sinusoidal signal to the lamps at its lowest operating frequency, which provides the greatest power to the lamps.  The ballast circuit may provide a momentary low-frequency, high power cycle to heat the lamp electrodes just prior to lamp start-up.  Power to the lamps for start-up and dimming is reduced by increasing the frequency to the tank circuit, thereby minimizing erosion of the lamp electrodes caused by high voltage.

Inventor: WELBORN HOWARD C JR
IPC: C08F4/68
Filed: 1987-09-01
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE          An olefin polymerization supported catalyst comprising the supported reaction product of at least one metallocene of a metal of Group IVB, VB, and VIB of the Periodic Table, a non-metallocene transition metal containing compound of a Group IVB, VB, or VIB metal and an alumoxane, said reaction product formed in the presence of the support.  The supported product is highly useful for the polymerization of olefins especially ethylene and especially for the copolymerization of ethylene and other mono and diolefins.

Title: Resin composition and film suitable for agricultural covering material
Inventor: NISHIMURA TOSHIHIRO
IPC: C08J5/18
Filed: 1987-09-04
Granted: 1992-08-25
Abstract: Abstract of the Disclosure A film suitable for an agricultural covering material is formed from a resin composition comprising a blend comprising (A) an ethylene/.alpha.-olefin random copolymer having a low melt flow rate and (B) an ethylene/.alpha.-olefin copolymer having a high melt flow rate.  The random copolymer (A) has a density (DA) of 0.935 to 0.950 g/cc and the random copolymer (B) has a density (DB) of 0.905 to 0.935 g/cc, and the density (DB) of the random copolymer (B) satisfies the requirement of DB ? 0.9DA + 0.09 in which DA stands for the density of the copolymer (A).
