    Abstract: A component (17) for determining the force (F) acting on a movable, force-transmitting draft (upper, top) link (20) of a tractor housing (10) has a measuring system (25) in its longitudinal bore (24). The measuring system (25) has a permanent magnet (26), which is arranged in the direction of the acting force (F), and one Hall element (28, 29) each above and below in the region of the tensile and compressive stresses, respectively. Changes in the permeability of the wall of the component (17) which occur under stress lead to a change in the magnetic field lines (lines of force) which penetrate the Hall elements (28, 29). The voltages thereby produced yield a signal which is proportional to the acting force.

    Abstract: A pressure medium-tight inductive pickup for a fluid control element has a pressure pipe composed of a non-magnetic material, a magnetic core received in the pressure pipe, connecting means at the open end of the pressure pipe for pressure-tight connection of the pressure pipe with the control element, a spool body surrounding the pressure pipe, a housing surrounding the spool body and having an axis, and an adjusting element for adjusting zero position of the pickup, wherein the spool body is axially displaceable on the pressure pipe and in the housing, and the adjusting element is formed as a worm drive adjustable from outside and arranged so that the spool body is coupled with the worm drive in a play-free manner in an axial direction.

    Abstract: The injection-molding machine is operative when activated for performing a complete injection-molding cycle. The machine includes a mold defining a mold cavity, a plastifying and injecting screw, and an hydraulic cylinder-and-piston unit for driving the screw. During the course of a single injection-molding cycle, negative-feedback control of the pressure in the mold cavity undergoes an automatic transition into negative-feedback control of the pressure in the hydraulic cylinder of the cylinder-and-piston unit. The transition is selected to be abrupt or gradual, and if gradual there will be a transitional interval during which a composite negative-feedback control of both the mold cavity and hydraulic cylinder pressures is occurring.
