A measurement transducer and program controller for automatic mechanical handling

Manned mechanical handling is gradually being augmented by automatic systems, and it is appropriate to review manufacturing processes in this connexion. The principles and use of linear and rotary electromagnetically-coupled measurement transducers giving the required information in the form of a change of phase of an electrical signal are discussed. The extent to which transducers can be used as the basis of automatic systems for point-to-point transportation as, for example, in automatic warehousing is described.
