According to one implementation, a preform shaping apparatus includes a rigid mold and a pressurizing jig. The rigid mold has a shape corresponding to a shape of a preform which has been shaped. The pressurizing jig presses an unshaped material of the preform to the rigid mold at different positions and different timings. Further, according to one implementation, a method of shaping a preform includes: producing the shaped preform by pressing an unshaped material of the preform to a rigid mold at different positions and different timings; and using a pressurizing jig for pressing the material. The rigid mold has a shape corresponding to a shape of the preform. The pressurizing jig is adapted to apply pressures on the material at the different positions and the different timings.

A trash compacting apparatus including a container, an air pump, two or more inflatable air bladders, an air distributor, a load plate, a load sensor, a pressure sensor, a controller unit, and an interface unit is disclosed herein. The apparatus may operate as a standard trash container and may further include a lid. The apparatus may be operated by the user or by a programmable controller unit to inflate the air bladders, thereby compressing trash contained within the apparatus and reducing the total volume of the trash.

A high-pressure pump comprising an elongated casing and a hollow interior formed along a central axis thereof. At least one partition may be axially fixed within the elongated casing such that it divides the hollow interior. First and second pressure differential devices may be disposed on opposite sides of the at least one partition and each have a rotary shaft extending there through. A first rotary shaft extending through the first pressure differential device may be axially fixed by the at least one partition and rotationally fixed to a second rotary shaft extending through the second pressure differential device. The high-pressure pump may be driven by a servomotor and used in a high-pressure press.

The present disclosure provides a device transferring apparatus and a device transferring method, comprising: a controlling component and a punching component, the punching component is located at one side of the controlling component; the punching component comprises at least one punching head movable in a first direction; and the controlling component comprises a protruding portion corresponding to the at least one punching head and capable of protruding toward the corresponding punching head, the protruding portion pushes the punching head to move in the first direction by protruding the protruding portion.

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.

A press device includes: a press head having: a press plate, a chamber base body and an elastic packing; and a provisional pressing unit having: a provisional pressing plate which transmits a provisional pressing force, and a provisional pressing force applying mechanism which gives a provisional pressing force to the provisional pressing plate. A main pressing force is generated to a work placed on a press surface by introducing a pressurized fluid into a chamber from a pressurized fluid source in a state where the elastic packing is deformed by compression by a provisional pressing force. The press device further includes a suppression unit which restricts the displacement of the provisional pressing plate in a counter provisional pressing direction by suppressing the movement of the provisional pressing plate in the counter provisional pressing direction.

Composite compaction system and method of use are presented. A method of supporting a composite compaction system is presented. A number of morphable bag supports of the composite compaction system is held in a retracted state. A contact face of a vacuum bag of the composite compaction system is placed in contact with a composite material on a support structure. The number of morphable bag supports is placed in an engaged state to conform to the support structure.

A system for compacting waste includes a trolley and a cabin monument. The trolley or the cabin monument has a compacting device. The compacting device includes a cover with a bellows that is arranged on the lower face of the cover and is designed to be movable between a folded-together position, in which the bellows interior has a first volume, and an unfolded position, in which the bellows interior has an enlarged second volume. By suctioning fluid from a container interior formed in the trolley by means of a first cover channel arranged in the cover of the trolley, the bellows can be moved into the unfolded position such that the bellows protrudes far enough into the container interior that the waste container and/or waste in the waste container is compacted.

A method of impregnating a fiber preform with an impregnation composition, includes applying a liquid on a structure, the structure including a chamber in which a fiber preform for impregnating is present, the chamber being defined between a rigid support on which the fiber preform is placed and a wall, the wall having a face situated facing the fiber preform; and an impregnation composition for impregnating the fiber preform, the impregnation composition being present in the chamber; the liquid being applied against the wall on its side opposite from the chamber, the wall being configured so that its face situated facing the fiber preform conserves its shape during the application of the liquid, the applied liquid enabling sufficient pressure to be created to move the wall towards the rigid support and impregnate the fiber preform with the impregnation composition.
