Absolutely beautiful work! These were the original Weyland-Yutani company logo and also doubled for flight crew. The larger ones, about three and a half inches wide denoted command officers and the smaller, about two inches were flight officers.
Thanks a lot, in the web I found two different versions of it. First the one used for patches and a second one used on blueprints. The one you see in my gallery is the one from the blueprints.
