Abstract: TO ALL WHOM IT MAY CONCERN: Be it known that I, William E. Glenn, citizen of the United States, residing in the State of Florida, have invented an improvement in METHOD AND APPARATUS FOR ENCODING AND DECODING VIDEO of which the following is a SPECIFICATION ABSTRACT OF THE DISCLOSURE The disclosure is directed to an apparatus and method for encoding and/or decoding video signals for use in a compatible high definition television system or in other applications. In a form of the disclosure there is provided an encoder which includes means for storing an input frame as an array of digital pixel values, and means for interrogating the stored array and for generating a sum signal and at least one difference signal. The sum signal is representative of the sum of the pixel values in a group of pixels. The difference signal is representative of the difference between the total of the pixel values in some of the pixels in the group and the total of the pixel values of other pixels in the group. The sum signal and the difference signal are generated for a multiplicity of groups which cover the video frame. The sum signal is generated at a relatively high information refresh rate and the difference signal is generated at a relatively low information refresh rate. The decoder includes means for storing the sum signal and each of the difference signals, and means for combining the sum and difference signals to obtain an output pixel value for each pixel of an output video frame. In another form of the disclosure, electronic processing is performed to obtain low and high spatial frequency component representations of the image represented by the video signal, and these are stored in a digital memory in the encoder. Output frames of the low spatial frequency component representation are produced at a fast frame refresh rate, and output frames of the high spatial frequency component representation are produced at a slow frame refresh rate.

Abstract: "High DC Voltage Generator"                          ABSTRACT      The primary winding of a stepup transformer is energized by a time-varying current for inducing a high voltage pulse in the secondary winding of the transformer in response to a rapid change in the time-varying current.          A plurality of first diodes and a plurality of capacitors are arranged to form a voltage multiplier for multiplying the amplitude of the high voltage pulse and storing the multiplied pulse on the capacitors to develop a high DC voltage.  A second diode is connected in a circuit between one end of the secondary winding and ground so that a current may flow in a loop through the first and second diodes in response to the high voltage pulse and potentials of opposite polarities may develop across the secondary winding.  The second diode provides a capacitance in series with the distributed capacitance of the secondary winding, thus reducing the total capacitance to permit ringing to occur at a desired harmonic frequency of the high voltage pulse.

Abstract: PROCESS FOR REMOVING SULFUR AND            ASH FROM COAL     ABSTRACT OF THE DISCLOSURE         A process is disclosed for removing sulfur and ash, particularly clay and pyrite from coal particles having a mesh size of 30 or less.  A slurry of coal particles is agitated in an ultrasonic mixer to separate the contaminants from the coal and weaken chemically-bonded contaminants on the coal surface.  The clay and pyrite particles are dispersed as a colloid in the aqueous medium of the slurry.  Treat-ment of the slurry with sonic energy also subdivides the particles along ash or clay seams.  The slurry is then separated in a centrifuge and in froth-flotation cells so that the coal particles greater than 2 microns are recovered and a slurry is again formed.  The repulped slurry is then treated with sonic energy and ozone to release further quantities of surface components from the coal particles.          The slurry is again treated in a centrifuge and coal particles 2 microns and greater are recovered.  The slurry is normalized before each treatment with sonic energy and ozone to a pH of 6-9 to maintain the released contaminants as colloids suspended in the aqueous medium of the slurry.

The radiation absorbed and/or emitted by the excited sample or sample preparation is sensed, and a plot is produced of the excitation and/or emission wavelengths against intensity, or in certain circumstances of the emission wavelengths against the excitation wavelengths.  It can then be determined from the characteristic profile so obtained whether the hydrocarbon content of the sample incorporates only the oil base of the drilling mud or a combination of this oil-base and native hydrocarbons.

Abstract: TRIMMING OF POLYESTER CONTAINER USING A LASER                 ABSTRACT OF THE DISCLOSURE           A plastic jar  is  formed by blow molding a combination adapter and jar and thereafter the jar is cut from the adapter using a laser beam. The jar may be blow molded from a preform which is of an injection molded laminated construction so that the wall of the jar is formed of plural layers. The heat generated by the laser beam will melt and bond together these layers as  opposed to permitting delamination as would occur should the jar be cut from the adapter by a knife or the like.  The  cut  surface  of  the  jar  forms  the  mouth defining surface of the jar and it is preferred that the cut be inclined at a slight angle to a plane normal to the  axis  of  the  jar.  Damage  to  the  diametrically opposite surface of the jar by portions of the laser beam being utilized for cut-off passing through the jar is prevented by a pressurized gas supply tube which is in the path of the laser beam and serves as an absorber for stray rays.

Abstract: COSINE SIGNAL CORRECTION CIRCUIT     Abstract A cosine signal corrector circuit as for use in a decoder for a system wherein an information signal is transmitted in the form of one trigonometric transform function of that signal.  The second trigonometric transform function signal, required for decoding the information signal, is obtained by first deriving the Hilbert transform of the transmitted signal and phase inverting it, producing an approximate second transform function signal.  The decoder produces the sum of the squares of the two transform function signals, and the difference between that decoder output and 1.0 is an "error" signal.  Under the control of the signum signal of the approximate second transform function signal, the error signal is added to the approximate second transform function signal to produce an accurate second transform function signal.  Even if the first transform function signal and its Hilbert transform approach zero at the same time, the circuit provides the correct polarity for the error signal.
