Various embodiments of high pressure presses and related methods of manufacturing and operating such presses are described. In one embodiment, a cubic press is described having press bases with spacers disposed between adjacent press bases. Sets of two or more tie bars are also disposed between adjacent press bases. The tie bars are placed in a state of compression while the spacers are placed in a state of compression. During operation, the press bases may become displaced relative to one another such that additional tension is experience by the tie bars while the amount of compression experienced by the spacer is reduced. The tie bars exhibit a relatively small cross-sectional area as compared to the cross-sectional area of the spacer.

A cartridge assembly having a chamber for containing hydraulic fluid, an intensifier element capable of reciprocating in the chamber and displacing the hydraulic fluid responsive to a drive system acting on the intensifier element, and a piston capable of reciprocating in the chamber and being displaceable responsive to a change in the pressure of the hydraulic fluid. The cartridge assembly is configured so that when the pressure in the fluid increases responsive to a first force being applied by the drive system on the intensifier, the hydraulic fluid will exert a second force on the piston, the second force being greater than the first force; the mass of the hydraulic fluid being substantially conserved within the cartridge assembly.

A tampon for feminine hygiene, having an insertion end, a recovery end, a recovery tape, and a longitudinal axis. The tampon is made of compressed fibrous material and has an outer surface that is at least partially provided with spirally shaped, pressed longitudinal grooves. The grooves define spirally shaped longitudinal ribs. Also disclosed is a method for producing the tampon.

The invention is directed to an apparatus for making conical bellows for air springs. The apparatus includes a clamping/spreading device transferable between first and second end positions corresponding to an introduction position and a vulcanization position, respectively. The external diameter of the device in the first end position is less than the external diameter thereof of the second end position. The device has clamping segments which in the introduction position are converged so that the external diameter of the device enables an air spring bellows preform to be pushed over the device, and the clamping segments in the vulcanization position are diverged increasing the external diameter of the device so that the bellows preform is pressed tightly against the corresponding external form from the inside. Open gaps because of the enlargement of the external diameter of the device remain between the clamping segments.

A press apparatus and a press including the press apparatus include a circular nest and a circular pressure shoe made up of press blocks formed as radial segments with an inside diameter corresponding to the diameter of the circular nest. The press blocks are fitted to actuators to move the press blocks between a first position in which the press blocks are radially outwardly spaced away from the nest and a second position the press blocks are radially inwardly disposed so that the inner radii of the press blocks are aligned to form a circle concentric with the circular nest.

A method for manufacturing hard-metal pressed articles includes providing a die that forms a cavity for producing a pressed article with at least one cutting edge and at least one chip breaker groove that is associated with a chip space. The step of providing the die providing a movable mold part and a movable mold body. The mold part has an operative surface, wherein the mold part at least sectionally defines the shape of a pressed article with the operative surface, and wherein the mold part is feedable in a first feed direction. The mold body has a rod-shaped operative section for producing a through-hole in the pressed article, wherein the mold body is feedable in a second feed direction. The first feed direction and the second feed direction are inclined at an angle of at least 45? to each other. The pressed article is formed from a hard-metal powder that is introduced into the cavity and compressed there in at least one main pressing direction. Forming the pressed article comprises feeding the mold part and the mold body such that the mold body is positioned in the cavity with the operative section being disposed in an abutment area on the mold part in a powder-tight relative position. A device enables the manufacture of hard-metal pressed articles.

A device for producing meat products includes an assembly formed from a plurality of walls maintainable in a fixed relationship to one another during a joining operation, surfaces of the plurality of walls defining work surfaces disposed to surround raw pieces of meat placed therein to be joined. A drive mechanism is configured to drive the assembly, which can form a cooking container such as a cooking box, along a first axis in a reciprocating movement of at least 10 mm along the first axis at frequency of at least 1 Hz and to drive the assembly along a second axis in a reciprocating movement of at least 10 mm along the second axis at frequency of at least 1 Hz, wherein the first axis and the second axis are angled with respect to each other, and the drive mechanism drives the assembly at different frequencies along the first and second axes.

A system for making blocks for gravity energy storage includes an extrusion press machine with a receiving chamber for receiving raw material, a compaction chamber and a pressing wall driven by a piston to push the raw material into the compaction chamber to compact the material to form a block. One or more of a top wall, opposite side walls and the pressing wall are moved away from the a center of the compaction chamber to allow the block to elastically expand prior to exiting the compaction chamber.

Processing device of a makeup product comprising: a first plate provided with first mutually adjacent channels with parallel axes, of semicircle section, and a second plate provided with second mutually adjacent channels with parallel axes, also of semicircle section, the first and the second channels being configured such that, when the first plate and the second plate are overlapped with their respective channels facing each other, each pair of first and second channels forms a tubular element with circular section; the device having guides configured to allow the movement of a plate relative to the other, in a direction parallel with respect to the axes of the channels; and at least one movement system of a plate relative to the other.

A device for making a double-sided toothed belt has an inner mold having teeth and an outer mold. The outer mold includes segments arranged parallel to the longitudinal axis of the inner mold and mutually adjacent. The device has a force transmission element arranged on the radial outer side of the segments. A pressure vessel has a cylindrical wall surrounding the force transmission element. The force transmission element is formed as a bellows fastened with two ends in pressure-tight fashion to the pressure vessel. The force transmission element is arranged in a ring-shaped space formed between the wall of the pressure vessel and the radial outer side of the segments. The pressure vessel has a pressure medium bore which opens into the ring-shaped space radially outside the force transmission element. The segments and the inner mold each have one axial passage bore through which fluid can be conducted.
