Abstract: VOLUME CONTROL FOR CATV AND METHOD THEREFOR      Abstract A volume control circuit useful for remotely controlling volume through a CATV remote control unit uses a sound carrier demodulator to obtain an intercarrier sound signal.  The intercarrier sound signal is further demodulated to obtain a detected audio signal whose amplitude can then be easily controlled by an amplifier.          The gain of the amplifier can then be controlled from the remote unit.  The detected audio is then remodulated with the RF video carrier.  The remodulated audio is then summed with the video signal to provide an RF output signal having amplitude controlled audio.

Abstract: Porous Metal Abradable Seal Material Abstract Porous metal structures are especially useful as abradable seals in axial flow compressors.  Care-fully defined oxide content and density provide a superior combination of abradability and particulate erosion resistance.  The seals are comprised of 1-30 weight percent oxide and have 27-38 percent of the solid metal density.  A preferred seal is made by plasma arc spraying a mixture of 80Ni-20Cr and polymethylmethacrylate powders and then heating the resultant deposit in air to about 315°C to cause the polymer to flee.  The nichrome seal will have less than 15 percent oxide and a density of about 2.7 g/cm3, about 32 percent of the solid metal density.

Abstract: ELECTRONIC BATTERY FEED CIRCUIT      FOR TELEPHONE SYSTEMS            Abstract Resistive circuits are provided at the input of an electronic battery feed circuit feedback path for lowering the voltage level of feedback signals to a metallic signal feedback portion and a common mode signal feedback portion so a common mode amplifier can be implemented in a much lower voltage technology than line amplifiers of the battery feed circuit.  Additional resistive circuits at the feedback output apply metallic signals to complementary inputs of the tip and ring line amplifiers without requiring a phase splitting amplifier. In addition, signals derived from the feedback circuit are used to vary the supply voltage for the line feed circuit elements as a function of feedback signal level and to provide a common mode reference signal which causes the tip and ring amplifiers to be biased symmetrically with respect to ground and the variable negative supply.

Abstract: CONTROLLED TURN-ON THYRISTOR                Abstract of the Disclosure A multistage amplifying thyristor incorpo-rates integral current control resistor regions between adjacent thyristor stages for limiting turn-on current in all but the main thyristor stage.  The thyristor is essentially immune from di/dt turn-on failure without the need for external circuitry to limit di/dt in the thyristor.  Modulation of the current control resistor region during turn-on is prevented by adequately spacing or shielding the region from the emitter of each thyristor stage as well as by adequate spacing or shielding of the resistor region from a portion of the lowermost emitter region containing a turn-on plasma of the preceding thyristor stage.
