When the time machine is spinning, Nora and Hector wouldn't need to wear goggles nor their faces would deform as if wind was blown at them at high speed, since they air inside the enclosed cockpit is not moving, regardless of how fast the whole machine turns.
At 4:02 Nora is looking at the box containing the transducer and it says "Manufactured in U.R.S.S." The rest of the text is in English as well. However "U.R.S.S." is the Spanish acronym for the Soviet Union. The English acronym is USSR.
In the next scene after Nora and Hector are arguing after Hector's night out, they keep talking by the time machine. There is a yellow cabinet in the background with the legend "Flamable". Flammable with one M, which would make it Spanish. The rest of the label is in English.
