Abstract: A gas turbine engine comprises, in axial flow sequence, a fan assembly, a compressor module, a turbine module, and an exhaust module. The gas turbine engine comprises first and second engine mount planes. The first and second engine mount planes are configured to support gas turbine engine in machine body. The gas turbine engine has axial length L, with axial length extending from inlet face of engine to exhaust face of engine. The first engine mount plane is positioned axially along gas turbine engine at first engine mount plane position, with first engine mount plane position within a range of between 0.24*L to 0.32*L from the inlet face of the engine. The second engine mount plane is positioned axially along gas turbine engine at second engine mount plane position, with second engine mount plane position within a range of between 0.73*L to 0.79*L from the inlet face of the engine.

Abstract: A dental matrix clamp includes an elongate body and a matrix band mountable relative to the body so as to form a loop projecting at one end of the body. The clamp has a tensioning device operable on the band to tighten the loop, and a deflector member which engages the band to provide an inclined conformation thereto. The deflector member is adjustable transversely across the band between opposite positions at which it bears against opposite peripheral portions of the band. The clamp is a hand-held device used in dentistry to clamp a band around a tooth for retention and molding of filling material.
