Disrupters are actually based on an experimental German technology. The Nazis dabbled briefly with sonic disrupters. The technology had a couple of problems. First it wasn't mobile, they wasn't a battery powerful enough (at the time) for even one shot, let alone multiple shots. Second, they couldn't figure out how to direct the effect. It may have had some use as an omni directional mine, but even that was suspect, as power costs were enormous. It never really reached the prototype phase. If an effective carrier wave could be developed, the invention of the Music Amplifier could actually make the technology viable.
Warp Drive is pretty much the Alcubere (I'm misspelling this I know) warp drive, that was first theorized in the 40s or 50s.
