Headgear
| Глоссарий по стоматологии |
- Although doffing head covering has long since been abolished as a form of salute, there are occasions when it is still considered appropriate. one obvious example is during religious services. in addition, it is unwritten law that junior and warrant officers remove their caps when in the wardroom, while all officers uncover when passing through cap- 149 headgear tain’s country or flag territory (although they do not do so when in full dress and wearing a sword). it is also considered courteous for officers to pass bareheaded through crew quarters at mealtimes, and to remove caps if visiting the sick bay. unlike the united states army and air force, british armed forces and united states naval and marine personnel never salute when the head is uncovered.
- The part of a drilling machine or apparatus that remains on the surface at the collar of a bore¬hole. the term seldom is so used by american drill operators, as they apply it to protective head cover¬ings worn by miners, aviators, and soldiers—similar to head coverings referred to as tin hats or safety hats by drillers.
