  • Coupling ducts or the like
    Patent number: 5125226
    Abstract: A removable section of duct is sealingly coupled to a relatively fixed length of duct by means of a flexible, preferably elastic, sleeve which is attached to one of the lengths of duct towards one end thereof and at its other end to a relatively stiff collar which is shaped to fit closely over the adjacent end of the other duct. The elasticity of the sleeve tends to retain the collar in position and to maintain a tight seal while permitting a degree of relative movement including longitudinal thermal growth.

  • Inlet particle separator
    Patent number: 4702071
    Abstract: To prevent dust and other debris from entering the compressor (12) of a gas turbine engine (10) an inlet particle separator (30) is provided. Air contaminated with dust and debris is induced into a scavenge chamber (32). An exhaust vent (35) is provided from the scavenge chamber (32) through which the contaminated air is ejected to atmosphere. Flow dividers (40,42,44) are positioned in the scavenge chamber (32) to ensure that the flow into the chamber is uniform around the inlet passage.
