Abstract

1303273 Angle or length measuring apparatus DR JOHANNES HEIDENHAIN 27 Feb 1970 [1 July 1969 23 Dec 1969] 9709/70 Addition to 1302762 Heading G4H The apparatus of the parent Specification 1,302,762 is modified in that it may be set in a mode in which when a reference mark is first sensed the state of the counter is stored and at each subsequent reference mark the stored value is entered in the counter. The apparatus may also be adapted to stop the counter when a reference mark is passed over in the backward direction and to operate the counter when a reference mark is passed over in the forward direction.
