Patent CA-1329487-C (CA)
Title: Turbojet thrust reverser with balanced pivoting doors
Inventor: DUBOIS CLAUDE A G
IPC: F02K1/70
Filed: 1989-09-29
Granted: 1994-05-17
Abstract: A thrust reverser is disclosed having a thrust reverser door with an outer door panel pivotally attached to an inner door panel which, in turn, is pivotally attached to an annular housing. The door panels are pivotable about parallel, but displaced pivot axes such that the inner door panel undergoes a greater range of motion between its closed and open positions that does the outer door panel. This enables the inner door panel to be flush with the upstream and downstream portions of the inner housing surface to provide a smooth airflow through the air duct during the forward thrust mode, while at the same time enabling an efficient operation of the door during the reverse thrust mode.

Abstract: The linear feed device is suitable for extremely slow feed rates or extremely small feed steps. It works with two motors (M1, M2) which drive a nut (16) and a screw spindle (2) via an intermediate drive (12-15; 22-25). The intermediate drives have slightly different transmission ratios, e.g., 1:0.340909 and 1:0.3414634. With a thread pitch of 2 mm of the spindle, this results, with the same direction of rotation of the motors, in about 0.0013 mm advance per revolution of the motor shafts. With the help of step motors, therefore, extremely small advance steps can be achieved.

Title: Bit synchronizer for short duration burst communications
Inventor: WALLEY GEORGE M
IPC: H04L7/04
Filed: 1990-01-10
Granted: 1996-09-10
Abstract: In order to rapidly acquire and track a clock signal embedded in a reduced length synchronization preamble, a bit synchronizer contains a digital counter, which counts clock signals from a local clock generator having a frequency that is a multiple of the frequency of the data modulations in the received signal.  The inverse of the most significant bit output of the counter sources the regenerated clock signal. In response to transitions in the monitored signal, the contents of the counter are coupled to an accumulator to provide successive measures of the  (phase) difference between the times of occurrence of the regenerated clock signal and the actual times of occurrence of the sync preamble transitions.  The contents of the accumulator are averaged over a prescribed number of monitored transitions and the resulting average is coupled to comparator, which compares the phase difference average output of the accumulator with the contents of the counter.  When the phase difference average coincides with the contents of the counter, the counter is reset, thereby aligning the phase of the regenerated clock with that of the monitored signal.   In addition,   as   the accumulator is updated, its input values from the counter are made available over a separate dedicated output link, to permit an attendant communications control processor to monitor  the tracking performance of the apparatus.
