Abstract

1474420 Control of position and velocity DANLY MACHINE CORP 19 July 1974 [4 Sept 1973] 32052/74 Heading G3N The subject matter disclosed is the same as that disclosed in Specification 1474419, but the claims relate to the instigation of a holding state of the member in response to the error signal exceeding a predetermined threshold, to aspects of the data block organisation, and control of member acceleration or deceleration to leave a line segment with velocity components appropriate to the succeeding segment. Reference has been directed by the Comptroller to Specification 1289504.
