    • A magnetic linear drive includes an elongated cylindrical armature which is supported for axial displacement in a guiding pipe made of a pressure-resistant material. Two axially spaced solenoid windings are mounted on the guiding pipe and are interconnected by a permanent magnet. The solenoid windings are provided with lateral magnetically conducting cores the ends of which communicate with annular grooves formed in the guiding tube. The grooves are filled with a magnetically conductive material forming the poles of the electromagnet. In the region of the poles, the armature is formed with control flanges of different depths which are acted upon by the magnetic flux to impart the axial movement to the armature. One end of the armature is formed with a measuring flange which cooperates with measuring coils mounted on the guiding pipe.

    • 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.

    • An electromagnetically actuated directional control valve is proposed, whose control slide (18) can be switched against a restoring spring system (45) into three switching positions (39, 41, 42) by a double-lift magnet (12). The spring system (45) has a strong spring (31) and a counter-acting weak spring (37), which are disposed on both sides of the control slide (18). With a pushing magnet (12), the control slide (18) is solely deflected against the weak spring (37), which is supported on it over the entire lift area. With a pulling magnet (12), a spring plate (32), which centers the center position (39), is pulled way from the control slide (18), which now is displaced by the weak spring (37), against the force of the strong spring (31). The tappet (29), connected with the armature, and the control slide (18) are separate independent components, which only form a frictionally connected operative connection.

    • An electromagnetically actuated directional control valve has a housing having a chamber, a control slider guided in the housing so as to be longitudinally movable, a restoring device centering the control slider and including a restoring spring and a spring plate, a magnet having an armature which can deflect the slider into a working position against a force of the restoring spring, a pressure tube communicating with the chamber in the housing via a pressure medium and receiving the armature. The pressure tube receives the restoring spring and the spring plate in its interior. The pressure tube also has a support which prevents the spring plate from falling out.
