The application of microprogramming to problem-oriented languages is described in terms of a simulated analog system on a digital computer. Microprogramming facilitates the development of a problem-oriented machine code, which can be simply generated from the problem-oriented source language by simple translation. In the system described a problem defined by differential equations is drawn up in the form of an analog diagram. The diagram is coded into an analog-oriented source language which is converted by translation into the analog machine code. The system also allows the machine assembly code to be freely used with the analog input in coding the supervisory and interrupt facilities that are incorporated in the overall system design.

A stability analysis of parametric phase-locked subharmonic tunnel-diode circuits capable of bistable phase operation has been made. A new type of computer-produced stability-chart plot shows regions of amplifications for desired harmonics used in directional-flow logic circuits, to allow design for subharmonic pumping. © 1967, The Institution of Electrical Engineers.

An alternative derivation of the linkages discussed by Dimentberg and Yoslovich is given. This derivation has led to the discovery of a generalized class of overconstrained spatial linkages, of which those of Dimentberg and Yoslovich are special cases. It is also shown that a family of multiloop linkages which has similiarities with the family of planar linkages can be derived from these generalized linkages. © 1966.
