Abstract: 811,888. Electric analogue calculating systems. FIELDEN ELECTRONICS Ltd. Nov. 22, 1956 [Dec. 30, 1955], No. 35720/56. Class 37. [Also in Groups XXIX and XXXVIII] A circuit for producing a current I proportional to the nth root of a mechanical force F, where n is between 1 and 2, contains a magnet 84 (Fig. 2), with two windings one of which is supplied with a controllable current from a D.C. source and the other is in series with a winding on the armature 80 and supplied from a source including a carbon pile 14 (Fig. 1). When the beam 36 is depressed it restricts the issue of fluid from the nozzle 44 and the resultant back pressure causes the diaphragm 54 to rise and compress the carbon pile. The current flowing through the two series windings of the magnet then increases and pulls down the beam which is attached to the armature 80. If the current in the second winding on the magnet is zero (as is the case in Fig. 1), F will be proportional to I<SP>2</SP> and hence I will be proportional to the nth root of F where n is 2. Application of current to the additional winding as in Fig. 2 modifies the value of n. The value of the current is shown on an indicator attached to the " load " terminals (Fig. 1).
