A radial press is provided having a first and a second ring structure extending about a press axis. Multiple press bodies are arranged about the press axis between the ring structures and are movably supported on support surfaces paired with the ring structures. The axial distance between the two ring structures can be changed using a drive system having a plurality of actuators oriented parallel to the press axis and distributed about the press axis. The support surfaces paired with one of the two ring structures are inclined relative to the press axis, and the press bodies are guided in a forced manner relative to the two ring structures in that the press bodies are equipped with guide grooves into which guide bodies engage.

A radial press is provided having a first and a second ring structure which extend around a press axis and a plurality of pressing elements, which are disposed around the press axis and are translatably supported on supporting surfaces associated with the ring structures. The axial distance of the two ring structures from each other can be changed using a hydraulic drive system, which has a plurality of hydraulic cylinder-piston units oriented parallel to and distributed around the press axis, the cylinder of each cylinder-piston unit being coupled to a first of the two ring structures and the piston rod of each cylinder-piston unit being coupled to the second ring structure. At least the supporting surfaces associated with one of the two ring structures are oriented at an inclination with respect to the press axis. An electromechanical rapid adjustment drive comprising a plurality of adjusters is also provided.

The press machine includes: a hydraulic cylinder configured to drive a slide; a plurality of hydraulic pumps/motors; a first port of each of which is connected to a first pressurizing chamber of the hydraulic cylinder; a plurality of servomotors axially connected to rotating shafts of the respective hydraulic pumps/motors respectively; a low-pressure accumulator to which second ports of the hydraulic pumps/motors are each connected; a high-pressure accumulator connected to a second pressurizing chamber of the hydraulic cylinder; and a slide position controller configured to control the servomotors so that a position of the slide matches a position corresponding to a slide position command signal based on the slide position command signal from a slide position commander and a slide position signal from a slide position detector.

Systems and methods of forming articles using electromagnetic radiation are disclosed. In some aspects, the system includes a plurality of forming modules movably mounted relative to an infeed mechanism. The infeed mechanism is configured to supply pre-form articles to the plurality of forming modules, and each of the plurality of forming modules includes a multi-segment mold disposed about an electromagnetic coil. The electromagnetic coil is configured to impart an electromagnetic force on the pre-form articles when supplied with electrical energy that urges the pre-form articles into contact with the multi-segment mold to produce the formed containers.

An example lavatory waste compartment includes a waste bin having a waste compartment for trash, a waste flap providing an opening into the waste compartment for insertion of the trash, and a manually operated trash compactor coupled to a ceiling. The manually operated trash compactor includes an expansion component connected to a compacting head, and a retraction component coupled to the expansion component to hold or retract the expansion component to a stowed position. An increase in temperature above a threshold temperature causes the retraction component to release the expansion component resulting in deployment of the compacting head into the waste bin. An actuation device is provided to deploy the expansion component from the stowed position, and when deployed, the expansion component blocks opening of the waste flap, and the retraction component causes the expansion component to retract to the stowed position via release of the actuation device.

A pressing assembly includes a button, a first connection portion, a receiving portion, a first elastic element, a pressing rod, and a pressing portion. The first connection portion includes a first end movably connected to the button and a second end connected to the receiving portion. The receiving portion defines a receiving space. A part of the pressing rod is movably received in the receiving space. The first elastic element is received in the receiving space. One end of the first elastic element is fixed, another end of the first elastic element resists the pressing rod. The pressing portion is connected to the pressing rod.

A bladder device is for moving a component of a web packaging machine that forms and encloses a food product in a food product package made of webs of packaging material. The bladder device has a bladder and a nipple stub coupled to the bladder and having a first end configured to receive a gas and a second end configured to dispense the gas into the bladder to thereby inflate the bladder and move the component of the web packaging machine. A collar coupled to the nipple stub such that the bladder is sandwiched between the collar and the second end of the nipple stub. The second end of the nipple stub has a depression and the collar has a boss that is oriented towards the depression such that tightening the collar on the nipple stub forces the bladder into the depression and thereby forms a fluid tight seal.

A modular press suitable for use in the manufacture of EWC products may include a plurality of frame modules coupled together and aligned along a feed path axis. Each frame module may have a generally planar body supported on a corresponding pair of bases, an elongate aperture, an upper and a lower platform within the aperture, and a platen between the platforms. Optionally, the ends of the aperture may be curved. A first actuator system may be operable to move the platen from a raised position to an intermediate position, and a second actuator system may be operable to press the platen downwardly from the intermediate position onto a workpiece within the aperture. Some modular presses include conveyor rolls and a third actuator system to raise and lower the conveyor rolls. In some embodiments, the actuator systems may be pneumatic actuator systems. Corresponding methods and systems are also described herein.

An indirect electrohydraulic draw-forming tool includes a body having a tubular cylindrical area, a chamber intended to be filled with a liquid, two electrodes, each of the electrodes having a portion arranged in the chamber, a punch. The tool also includes a piston mounted so as to slide in a sealed manner within the cylindrical area and sealingly defining the chamber. Moreover, the punch is carried by the piston on a face thereof that is opposite to the chamber.
