Title: Fluid torque-restraint system with optimized fluid expansion
Inventor: MCGUIRE DENNIS P
IPC: B64D27/00
Filed: 1992-04-22
Granted: 1993-10-12
Abstract: ABSTRACT                FLUID TORQUE-RESTRAINT SYSTEM WITH OPTIMIZED FLUID EXPANSION      A torque-restraint mounting system for connecting an aircraft engine to a structure including at least two hydraulic mountings and at least one other resilient mounting. At least two of the hydraulic mountings are fluidicly interconnected via a fluid filled conduit. This allows for the torque to be reacted between the aircraft engine and the structure by placing the fluid in compression. The relative torque-induced displacement occurring between the aircraft engine and the structure for any specific operating condition is counteracted by tuning the amount or volume of fluid within the torque-restraint system, or by tuning the coefficient of thermal expansion of the fluid. Thus, as the torque-restraint mounting system heats up, the aircraft engine will change rotational position such that its room temperature untorqued orientation can be maintained. This can have significant benefits in terms of increasing service life of the engine mounting system.

Abstract: An apparatus and method for transferring a data payload (SPE) from a first substantially SONET signal into a second substantially SONET signal of different frequency. A circuit (43a) for extracting the SPE bytes from the first SONET signal and sending the bytes, according to a first clock, to a FIFO (60) for storage; a circuit (47a) for obtaining the SPE bytes from the FIFO according to a second clock, for building the SPE into the second substantially SONET signal; and a circuit {70) for comparing the relative byte phases of the first and second clocks. To avoid read/write conflicts in the FIFO, the comparison circuit generates and sends a signal to the extracting circuit (34a) which causes the extracting circuit (34a) to change the byte phase at which bytes are sent to the FIFO. To adjust the SPE for frequency differences between the first and second substantially SONET signals, the comparison circuit (70) sends a signal to the circuit which builds the second SONET signal when the two SONET signals have slipped a byte relative to each other.
