Wow lots of questions lol, ok first up a Higbee Cut is a special type of thread arrangement that is cut at the beginning of the thread to provide positive identification of the first thread and to eliminate cross threading. The Higbee indicators are Notches or grooves cut into coupling lugs to identify by touch or sight the exact location of the Higbee cut.
Cant see mto find much about the Morse gate so it appears we have a research project on our hands for the group lol. A still alarm is a fire alarm transmitted silently, usually by telephone, rather than by sounding the conventional signal or bell apparatus. Still alarms are commonly used to alert fire and medical personnel as to what type of emergency they are responding to. Most of the time they will come on either maually by someone calling in something or by a digital dialer.
