Abstract
1332364 Programme controlled extrusion HUNKAR INSTRUMENT DEVELOPMENT LABORATORIES Inc 25 Sept 1970 [10 Nov 1969] 9135/73 Divided out of 1332363 Heading G3N The subject matter disclosed is identical to that of Specification 1332363, but the claims are directed to a control system for determining the relative positions of the die and the cooperating mandrel of the parison extruding machine, drawing attention to the electronic control arrangement.
