Abstract: ABSTRACT OF THE DISCLOSURE A microwave distributed-constant filter of a band-pass characteris-tic having at least one attenuation pole comprises resonator rods, each of which has an open and a shorted end and of which two first rods are inductively coupled in series through at least one second resonator rod.  The first resonator rods are capacitively coupled direct to each other with a pro-jection attached adjacent on at least one of the first resonator rods to the open end thereof.  The first resonator rods may be coupled directly to input and output terminals of the filter.  Alternatively, two third resonator rods may be interposed between the respective ones of the first resonator rods and the input and the output terminals.  The third resonator rods may be induc-tively coupled direct to each other.  As a further alternative, two fourth resonator rods may be interposed between the respective ones of the third resonator rods and the input and the output terminals with the third resona-tor rods inductively coupled direct to each other or with the third resonator rods capacitively coupled direct to each other by a projection attached adjacent on at least one of the third resonator rods to the open end thereof. The filter may be of the various coaxial types including the interdigital type.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for encoding and decoding of standard television signals are provided for enabling reception thereof in an intelligible manner only by authorized subscribers.  The scrambling of the video signals is effected by inversion of the video signals of some horizontal scan lines on a pseudo-random basis to produce a picture having some video signals inverted and others not inverted which is unpleasant to view and virtually unintelligible.  The scrambl-ing of the audio signals is effected by conversion of analog audio signals to coded digital audio signals.  A plurality of unique pulse coded control signals consisting of 32-bit binary pulse trains are transmitted separately to identify individual authorized subscribers and to provide information needed to unscramble the scrambled video and audio signals.          When there is a comparison between one of the pulse-coded control signals and a unique address code stored at a particular subscriber's receiver, unscrambling of the video and audio signals occurs in the same sequence as used for scrambling so as to provide restored video and audio sig-nals without degradation in picture and sound qualities.

Abstract: ABSTRACT OF THE DISCLOSURE:         A spark ignition reciprocatory internal combustion engine is provided with a primary induction system to direct fuel charge into a combustion chamber to swirl therein under all engine operating conditions via a primary intake valve, and a secondary induction system to direct fuel charge into the combustion chamber via a secondary intake valve only at high engine load.  The entire combustion chamber is formed by the clearance volume between the upper surface of a piston and the lower surface of the cylinder head and by a cavity formed in the cylinder head.  The primary intake valve is arranged within the lower surface of the cylinder head outside of the periphery of the cavity and the secondary intake valve within the bottom surface of the cavity so that  at low and intermediate loads the secondary intake valve will not impede the swirling motion of the fuel charge from the primary intake valve.

Abstract: MAGNETIZING AND DEMAGNETIZING TOOL          ABSTRACT OF THE DISCLOSURE:      A magnetizable iron core is surrounded by a magnetizing solenoid coil which can be energized by 60 hertz regular house power.  An article of magnetizable material to be magnetized is placed adjacent the core and the solenoid coil is energized. A normally closed dwell switch in series with the solenoid coil is activated by the magnetization of the iron core to move to an open condition to interrupt flow to the solenoid after first permitting current to flow in said solenoid coil momentarily. Upon such interruption of current flow to the solenoid, the arti-cle is magnetized.  To demagnetize an article, it is put in contact with the iron core, and means is provided to override the dwell switch.  The solenoid coil is continuously energized. The article to be demagnetized is then moved away from the iron core.  The resulting decreasing alternating current field completely demagnetizes the article.
