The beats are still there. They drop the bass frequencies and enhance the higher frequencies, so that the drums are covered by the bassline/drums in their tracks.
A good example of this is WTIL live at tr. where the kraftwerk sample is played. You can definately hear the kraftwerk beats on there
During an interlude about 3 minutes into the track, you can hear the ascending series of xylophone-like sounds from Home Computer. It doesn't sound like a direct sample of the KW sound, but it is very close. NOTE: Rob Holman adds that an early version of this track, on its same-titled single, was heavily based on The Robots but was withdrawn when Kraftwerk's land sharks drew near.
you can hear longer examples of the ascending xylophone-like sounds in the "echo and the bunnymen mix", although I don't hear actual kraftwerk beats on the "trancentral" version they start around 1:38 during "live at trancentral", around 2:56 after the harp sound on "echo and the bunnymen"
