A New Differential Analyzer
H. P. Kuehni, Harold A. Peterson · Transactions of the American Institute of Electrical Engineers · 1944
This paper describes a new 14-integrator differential analyzer recently placed in service by the General Electric Company at Schenectady. This analyzer has a mechanical interconnection system but has integrators of novel design in that a Polaroid follow-up system is used rather than the more usual mechanical torque amplifiers.
