Abstract: ABSTRACT    A differential thermocouple combustible gases detector is provided by coating one thermocouple junction of a differential thermocouple pair  with a catalyst and the other thermocouple junction with a non-catalyst.  Heated combustible gases react with the catalyst to liberate heat to the catalyst coated thermocouple junction in proportion to the concentration of combustible gases and proportionally raise the temperature of that junction above the non-catalyst coated junction.  The out-put signal from the differential thermocouple device is thus a signal indicative of the concentration of combustible gases.

Abstract: ABSTRACT OF THE DISCLOSURE      For damping torsional oscillations of an electric a.c. generator, a speed-sensing member, for example a tachometer-generator, is connected to the a.c. generator.  The speed-dependent signal generated by the speed-sensing member is supplied to a band-pass filter which is adapted to the natural frequency of the torsional oscillations.  The output signal of the band pass filter is supplied directly to the control angle determ-ining means of a converter connected to the generator.  In this way the power of the converter is modulated in such a way that the oscillations are damped.

Abstract: ABSTRACT This invention relates to a video communication system which permits images obtained from video equipment such as a projector to be modified graphically as the images are being projected.  The images are projected onto the lower surface of a screen through a dichroic crystal mirror.  The screen is semi-transparent which permits the operator viewing the screen from above to view the images while preventing the operator's hand or writing instrument from being viewed from below.  Various types of screen are disclosed but all are capable of permitting graphic information added to the upper surface of the screen by the operator to appear on the lower surface.  For example, the screen may comprise a lower clear transparent screen spaced from an upper black semi-transparent screen, the intervening space being filled with translucent particles such as chalk.  Pressure applied to the upper surface of the black screen causes a mark to appear on the lower surface of the clear screen.  The modified images are fed back to the dichroic mirror to a storage, recording or reproduction system.

Abstract: ABSTRACT OF THE DISCLOSURE     A tape cassette is so arranged that an endless tape stored in a tape accumulating portion in a cassette body, to which a front lid is pivotaly movably secured,to thereby assume an open position and a close position ' with respect to a front opening in the cassette, and pulled out of the cassette body is again drawn into the cassette body by means of a tape drawing reel mounted in a position displaced to one side from the center of the cassette body.  A pair of elastic members are disposed in an elastically contacting relation to each other, with the free ends thereof facing a tape discharge gate, within the cassette body, so that the endless tape can pass through the pair of elastic members.  The tape cassette further includes; a rotatably mounted, reverse rotation check member; and a flexible member attached at one end or in the intermediate portion thereof to the cassette body, with the other end maintained in pressure-contact with an elastic member surrounding the flank portion of the tape drawing reel.   The flexible member is slidably connected in a portion between the fixed portion and the aforesaid other end to the reverse rotation check member.          When the tape drawing reel is rotated in a reverse direction, the aforesaid other end portion of the flexible member is strongly pressed against the elastic member while being deformed, thereby strongly pressing the reverse rotation check member against the tape drawing reel, thereby impeding rotation in the reverse direction, of the tape drawing reel.

As this occurs, a cast article is formed of elongated crystals having longitudinal axes extending parallel to the longitudinal axes of the crystals in the starter element.  Each of the elongated crystals in the cast article is farmed of a plurality of cubic unit cells.  The sides of the unit cells of the elongated crystals in the cast article have the same orientation as the sides of the unit cells in the elongated crystals of the starter element.
