Abstract: A device for coupling a universal joint shaft to a power take-off shaft (1) of a tractor has a first coupling mechanism (48) that is non-rotatably arranged on the universal joint shaft. A second coupling mechanism (17) is non-rotatably arranged on the power take-off shaft (1) of the tractor. The first and second coupling mechanisms can be non-rotatably coupled to transmit torque. A coupling shield (7) is provided to couple the coupling mechanism (17, 48). The first coupling mechanism (48) is at least indirectly rotationally supported on the coupling shield (7). A locking mechanism (58, 58?) projects from the coupling shield (7). A bracket (2) is attachable on the rear of the tractor. The bracket (2) has at least one locking device (5, 5?) that is displaceable between an unlocked position and a locked position. The locking device (5, 5?) is displaced from the unlocked position into the locked position.

Abstract: A process and an apparatus for continuous casting of metallic materials in a semi-solid state is disclosed. A solid metallic material is processed by heating the material in a first container with an inductive heater to a temperature above the solidus temperature. The processed metallic material is then transported to a storage container, from there to an injection unit and subsequently to a casting tool.

Abstract: A device for measuring torque in a drive assembly includes a torque-loaded torsion element (9), such as a shaft, and a reference element (21) surrounding the torsion element (9). The reference element is correspondingly tubular in shape. A first tube end (22) of the reference element (21) is firmly connected to a first shaft end (10) of the torsion element (9). A second tube end (24) of the reference element (21) is supported on the second shaft end (11) of the torsion element (9). The two tube ends (22, 24) are each associated with a transmitter element (16, 34). The relative position of the transmitter elements (16, 34) in the direction of rotation around the rotational axis (8) is recorded by a sensor element (35). The sensor (35) is associated with a housing (1). The sensor (35) generates a signal each time the two transmitter elements (16, 34) pass and transmits signals to an evaluation unit (36). The evaluation unit (36) determines the torque applied from the offset of the signals.

Abstract: Apparatus for casting metallic materials, includes a processing device for preparing metallic material in free-flowing form and a storage container in communication with the processing device for receiving a continuous flow of prepared metallic material. An injection unit including a piston and cylinder arrangement is arranged separately from and connected to the storage container by a flow connection which includes a flow regulating device to control a flow therethrough. The storage container and the piston and cylinder arrangement are heated separately by a heating assembly, thereby ensuring short cycle times and establishment of great variability during a casting operation.

Abstract: A coupling assembly for agricultural implements has a friction coupling (1), an electromagnet (6) and control mechanism (7). The friction coupling (1) includes a friction assembly (4) which is loaded by a pressure plate (14). The pressure plate (14) is loaded by pressure springs (15, 16). The pressure plate (14) is adjustable by an actuating device (5) which includes an electromagnet (6) and an anchor plate (19). The control mechanism (7) includes a control member (27) which, by changing the electric current, regulates the pressure force of the pressure plate (14) during the coupling and/or uncoupling operation. The housing (2) and the hub (3) are associated with speed sensors (25, 26) which transmit a signal to the control mechanism (7) to relieve the load on the friction assembly. Thus, this prevents the friction coupling (1) from overheating.
