A mobile apparatus with a fluid pressure-operated implement mounted at a distal end of a boom includes a connection apparatus for selectively rotating the implement about an actuator axis at the distal end of the boom. The connection apparatus includes a rotary actuator and a pressurized fluid circuit for delivery of pressurized fluid through the rotary actuator to the implement. The pressurized fluid circuit includes channels establishing a fluidic connection axially through the rotating shaft of the rotary actuator. The pressurized fluid circuit facilitates passage of pressurized fluid through an internal, protected environment to the implement.

A method of manufacturing an electrode assembly includes positioning a layer stack comprising an electrode positioned between an electrode insulator and a support polymer in a vacuum bag, removing air from the vacuum bag thereby vacuum coupling the electrode to the electrode insulator, and removing the layer stack from the vacuum bag, where upon removal of the layer stack from the vacuum bag, the electrode remains vacuum coupled to the electrode insulator and the electrode insulator is in direct contact with the electrode, thereby forming an electrode assembly.

A drive control system of a hydraulic excavator includes a control device. When accelerating a turning body to a target turning speed, the drive control device controls an operation of the electric motor driving device such that the electric motor outputs high efficiency torque by which a highest electric power efficiency is obtained at the target turning speed. The control device controls an operation of an oil pressure supply device such that residual torque obtained by subtracting the high efficiency torque from target torque is output from an oil-pressure motor.

A cylinder includes a curved cylinder body, a first support member, and a piston assembly. The curved cylinder body defines a gas chamber passing through opposite ends. The first support member includes a support housing slidably mounted on the outer circumferential surface of the cylinder body and a first permanent magnet securely mounted in the support housing. The piston assembly received in the gas chamber includes a first piston member and a second piston member rotatably coupled to the first piston member. The first and second piston members respectively have a second permanent magnet which is arranged to be attracted to the first permanent magnet. When the piston assembly moves along the curved cylinder body from the first end to the second end in the gas chamber, the first support member moves with the piston assembly on the outer circumferential surface of the curved cylinder body.

A fluid pressure actuator including a fluid pressure cylinder having a first position detector and a second position detector, a piston body having a piston head and a rod, the piston head mounted on the rod and slidably accommodated in the fluid pressure cylinder, the rod including a first scale and a second scale, the first scale facing the first position detector and the first position detector configured to detect a position in a sliding direction of the piston body, the second scale facing the second position detector and the second position detector configured to detect a position of the rod in a rotation direction of the piston body, and a controller configured to perform a first positioning control of a position of the rod in the sliding direction and a second positioning control of the rod in the rotation direction may be provided.

An electrohydraulic device includes an extender which is arranged to be actuated by hydraulic fluid, and a rotor of an electric motor, the rotor being arranged to rotate about a part of the extender. The rotor may have an annular body which encircles or surrounds part of the extender. There is also described a related method of use and a marine vessel or platform where the device may be applied.

An extrusion device (11) for compound-containing containers (6), including a receiving chamber (12) for the container (6), a piston rod (13) which is displaceable relative to the receiving chamber (12), a motor (21) for moving the piston rod (13), a trigger member (26) for generating a control signal in response to actuation of the trigger member (26), and a control unit (31) for controlling the motor (21) is provided. The control unit (31) has a power module for connecting the motor (21) to a power supply (19), and a separate signal input which is electrically connected to the trigger member (26). The power module connects the motor (21) to the power supply (19) when the corresponding control signal is present at this signal input. A method for controlling such an extrusion device (11) is also provided.
