My guess is that they did actually have working prototypes; some of the patents have fairly detailed drawings. Some of the things being claimed in the patents aren't even particularly hard to build; standard feedback-control-system stuff that no doubt some Honeywell engineer could prototype. They just never brought them to market, which is a different issue.
