Abstract: The invention is an integrated hydraulic control circuit for actuating the thrust reversers and variable exhaust nozzle on high preformance gas turbine engine powered aircraft. The hydraulic circuits for both systems are integrated into a single housing and are served by common elements. The circuit for the deployment and stowage of the thrust reverser buckets is hydraulically sequenced inhibiting the application of hydraulic power to the actuators prior to withdrawal of the locking pin. In a like manner, the thrust reversers must be fully retracted before the locking pin is deployed. The hydraulic circuit for the thrust reversers also includes a pressure compensating circuit which reduces the pressure applied to thrust reverser actuators with the thrust reversers in the stowed position.

Abstract: A scragg mill which includes a pair of driven saw blades, a log carriage for conveying a log between the saw blades and a husk frame assembly for supporting the saw blades and a drive source for the saw blade. The husk frame assembly includes a pair of husk frames telescopingly interlocked with each other so as to enable the two saw blades to be shifted relative to each other.
