Abstract: ABSTRACT OF THE DISCLOSURE     A combustion system which includes a catalytic burner of a fiber matrix com-position for combusting an air-fuel mixture with high efficiency and low NOX emissions. The burner matrix is comprised of high temperature resistant fibers randomly oriented and packed together to form interstitial spaces for the mixture flow path. The thickness of the matrix and density of the fibers are within an optimum range for maintaining combustion in a shallow heterogeneous reaction zone at a temperature below the use temperature of the fiber by radiating heat transfer from the zone. The matrix forms a heat insulation barrier to maintain the matrix temperature at the inlet side below the ignition temperature of the mixture for preventing flashback. Strands of a catalytic material can be interspersed through the matrix. The matrix can be in the form of a hollow cylindrical shell for use within the combustion chamber of a firetube boiler system.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides a simple, yet highly accurate device for synchronizing the speeds of two power-driven machines having separate, variable speed power-drives.  A pair of shafts are respectively connected to the two machines and mounted in opposed concentric relationship for rotation in opposite directions at rates respectively proportional to the speed of rotation of the two machines.  A differential unit is connected between the two shafts, such unit having equal size input and output sun gears respectively connected to the shafts.  The plane-tary output of the differential unit is connected to a speed control element for at least one of the motors respectively driv-ing the machines to vary the speed of such machine to bring it into rotational synchronization with the other machine.  In ac-cordance with a modification of the invention, if angular syn-chronization is also desired, a one-way clutch is provided between one of the shafts and its respective machine which is disengageable by a minimal torque produced by a difference in the rotational speed of the two shafts, and re-engages only in a fixed angular position when the two shafts are again brought into rotational synchronization.

Abstract: RCA 76,431/76,431 PROTECTION CIRCUIT FOR INTEGRATED CIRCUIT DEVICES            ABSTRACT OF THE DISCLOSURE Disclosed is a protection circuit which may be used, for example, in a television receiver to protect circuitry inside an integrated circuit from damage due to high-voltage transients. The protection circuit comprises a PNPN structure forming a silicon control rectifier (SCR) and a resistive element integral to the SCR structure. In one embodiment the resistive element is a linear resistor and in another embodiment is a non-linear resistive element in the form of a diode-connected transistor.  The SCR and the resistive element are arranged to form a two-terminal, high-current protection circuit which is rendered conductive when the potential difference across the two terminals is greater than one forward-biased PN junction voltage drop. One terminal of the protection circuit is connected to an input or output terminal of the protected circuit, and the other terminal is connected to the most positive power supply potential.  Transient voltages appearing at the integrated circuit terminal greater than one PN junction voltage drop above the positive power supply potential cause the protection circuit to conduct current, thereby dissipating the energy of the high-voltage transient and protecting the integrated circuit from damage.

Abstract: A B S T R A C T         In the production of magnesium by electrolysis of a fused salt the metal is collected over a body of the fused salt under a heavily insulated cover to reduce heat loss from the molten metal unde? a sub-stantially non-oxidising atmosphere.  The electrolyte is held down to a controlled temperature somewhat above the melting point of magnesium by means of a heat exchanger which projects into the fused electrolyte and is arranged so as to avoid significant uptake of heat from the supernatant molten metal.   This arrangement permits the electrolyte temperature to be controlled with reduced formation of sludge and extended cell life by avoidance of exposure of the electrolyte to atmosheric  moisture.
