发明名称	Polar coordinates register for destination on street map - provides distance vector between start and destination points on transparent disc with segments divided into angles
摘要	The navigation appts. accepts communication zones as well as destinations. A transparent disc has a scale divided into angles and a ruler with a linear scale The disc (1) has segments with angles marked in deg. The segments (3) with increasing radians are arranged concentrically about a centre point (2). The radius of one segment is a whole number multiple of a unit value, pref. a centimetre. The disc has a series of angle graduations (4) extending beam-like from the centre point. The angular distance or scale is pref. from 5 to 10 deg. A larger angle (5) can be inserted between the latter. ADVANTAGE: Detailed but with simplified mfr.
