change Title (uppercase/lowercase) and font

Hello everybody,
I have a mayor problem with my front page.

let’s have a look:

The title “BERÜHRUNGSLOSE LÄNGEN- & GESCHWINDIGKEITSMESSTECHNIK” above the meta-Slideshow shouldn’t be written in big letters, as it does, but with normal letters – just like this: “Berührungslose Längen- & Geschwindigkeitsmesstechnik“

I tried anything and changed things in my stylesheet but it didn’t work.

Could you please give me a hint?

Withz kind regards,
M.
