    (54) System for measuring and controlling the angular position of the vessel of membrane presses in general


    (57) A system for measuring and controlling the angular position of the vessel in horizontal membrane presses comprises a rotary coder device (2) associated with the longitudinal axis of the vessel and arranged to constantly measure the actual position of the vessel relative to a reference position, and an operating and control unit (3) operationally connected at its input (A, B) to said decoder and at its output (C) to the vessel drive unit (1), and comprising at least memory means arranged to memorize specific angular operating positions of the vessel, and at least means (30) for selecting said specific angular positions; said unit being arranged to compare the actual position of the vessel with said specific memorized positions, such that each time the former coincides with one of the latter the unit emits a signal to halt the drive unit or to restart it in one direction or the other.
