Abstract: ABSTRACT OF THE DISCLOSURE          -An exhaust gas recirculation system for an internal combustion engine employs a recirculation control valve in a passageway connecting the engine exhaust passage to the engine intake passage downstream from the throttle valve.  An air conduit having an air control valve therein furnishes atmospheric air to the intake passage downstream from the throttle valve. Vacuum responsive actuators are provided for each of the control valves and they are operated by vacuum pressure regulated by a regulating valve, which is itself responsive to differential pressure between vacuum intensity in the intake passage upstream from said throttle valve and modified atmospheric pressure.  The modified atmospheric pressure is obtained downstream from a variable throttling valve mounted in a bypass passage connected to the air conduit upstream and downstream with respect to a restriction therein.  If atmospheric pressure correction is required, a sealed flexible bellows sur-rounded by atmospheric pressure may be connected to influence the operation of the variable throttling valve.

Abstract: P2222.01 ABSTRACT OF THE DISCLOSURE A reciprocating traveling carriage supporting a fluid-carrying lance in a soot blower assembly. A single reversible motor drives an endless chain over a pair of primary sprockets supported on shafts passing through the housing of a traveling carriage. The shafts are further provided with spur gears having different number of teeth which, however, engage one another. In operation, the endless chain rotates the primary sprockets which causes the spur gears to rotate at un-equal speeds due to the unequal number of teeth on each spur gear. Since the links of the endless chain necessarily move at a constant speed, the traveling carriage will advance along the endless chain in order to compensate for the different speeds of rotation of the spur gears. Simultaneously, the lance is rotated about its longitudinal axis as it is driven along the endless chain. The rotation is also accomplished by the driving output of the single motor, A flexible hose provides fluid to the lance. The flexible hose is supported by a trough-shaped underlying support. Additionally, parallel guide rails are provided which extend longitudinally beneath the lance and on both sides of the flexible hose. When the traveling carriage and lance are reciprocated, the flexible hose is rolled out of the support, yet is maintained in relative vertical position by the guide rails.
