Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for reducing the susceptibility of line signal repeaters to induced currents includes a zener diode/diode stack which provides the line repeater with a constant voltage drop when the DC line current is above the minimum required bias current.  When the DC input current plus an induced component from the line exceed the load requirements of the repeater, the excess current is conducted through a blocking diode to charge an energy storage device.   But, when the DC input current and the induced component oppose each other, the energy stored in the energy storage device is used to supplement the input current to just maintain the required repeater voltage.

Abstract: BE 19'005 RECIPROCATING PISTON BEAM ENGINE              ABSTRACT OF THE DISCLOSURE       In the disclosed internal combustion engine opposing identical pairs of pistons drive back and forth arm ends of a centrally pivoted beam which is symmetrical about its pivot.          Torque is extracted from the beam through an eccentric mechanism which is located between the end of one arm and the pivot.          The other arm is provided with a symmetrically located second eccentric mechanism symmetrically spaced from the pivot and substantially identical with the first as regards the dynamic balancing, but not connected to the same output shaft as is the first eccenter mechanism. Also disclosed are combinations in which two or more such engines are connected together as units so that one or more of the units may be completely decoupled from the output shaft and thus inactivated. A special controllable coupling connecting the main shafts of such multiple units permits selective disengagement of the units and synchron-ized reengagement with predetermined relative angular orien-tation. Lubrication of the beam pivot is particularly effective when the beam is pivoted on the rotating output shaft of the engine, since that permits an effective lubricant film to be maintained.
