A linear actuator is disclosed. The linear actuator comprises a cylinder portion and a base portion. The cylinder portion comprises a housing defining internally a compression chamber for containing a fluid and comprising a piston assembly that can reciprocate within the compression chamber. The housing further defines a cylinder port in fluid communication with said compression chamber. The base portion defines a first base port and a second base port and a passage extending therebetween fluidly communicating the first base port with the second base port, and comprises valve means operable to control the flow of fluid through the second base port, in which the valve means is actuatable between an open condition in which the flow of fluid through the second base port is permitted, and a closed condition in which the flow of fluid through the second base port is substantially prevented. The cylinder portion is releasably engageable with the base portion such that the cylinder portion and the base portion may be arranged in an engaged condition in which engaged condition the cylinder port and the second base port are in fluid communication.

A baling press has a horizontal construction, for compaction of loose material, a pressing channel having a fill-in opening, a pressing plate that can be displaced in the pressing channel, a pressing surface that stands in contact with the material to be compacted, multiple hydraulic cylinders coupled with electro-hydraulic drive assemblies for generating a pressing force, for advancing the pressing plate for the purpose of introducing the pressing force into the filled-in material, as well as for returning the pressing plate to a starting position, and a control and regulation system configured for monitoring the spatial orientation of the pressing surface and keeping it constant during the advancing movement of the pressing plate.

The disclosed forming apparatus includes a frame. The frame defines a vertical axis, a horizontal axis, and a longitudinal axis. A carriage is movably connected to the frame. A first stomp foot is movably connected to the carriage such that it may move along the vertical axis. A first end effector is movably connected to the carriage. The first end effector is controlled by an actuator. The disclosed method for forming a composite part includes applying at least one ply of composite material over a forming surface of a forming tool and deforming the at least one ply of composite material over the forming surface of the forming tool with a forming apparatus.

A press including a passive load leveler for bonding integrated circuit wafers, chips or substrates. The press includes a press frame, a press ram moveable relative to the frame, a first platen coupled to the press ram, and a second platen coupled to the press frame. The load leveler is coupled between the press frame and the second platen, and includes a main body having a first surface coupled to the press frame a plurality of pistons extending from the main body through a second surface and being in contact with the second platen. Each of the pistons is positioned within a piston chamber that is in fluid communication with a network of channels within the main body, where the pistons move relative to each other through a working fluid within the channels so as to maintain the first and second platens parallel to each other under the ram pressure.
