There are three types of "xxxcharged" piston engines.
Supercharger used gear drive from the engine crackcase to turn a compressor to compress the intake air.
Turbocharger uses engine exhaust to turn a turbine which drives the compressor on the intake.
And there is the "turbocompound" which uses BOTH systems to compress the intake air. DC-7s and Super Constellations used turbocompound engines (which proved to be somewhat unreliable!)
Possibly the term in the paper "Turbo Supercharger" was referring to a turbo compound.
