The present invention relates to a punch unit of a powder press, wherein the punch unit is assembled from at least two parts, in this case comprising a headpiece as the first part and a widening region, adjoining the headpiece, as the second part, wherein the widening region flares to a diameter of a punch bolder which is directly attachable to an end, located away from the headpiece, of the widening region. Furthermore, punch units of a powder press that slide one inside another, a powder press itself and a method for operating a powder press are proposed.

A bottom fillable espresso cartridge base and apparatus and method for filling and plugging the bottom of the espresso cartridge base. The espresso cartridge base includes an open bottom and a press in bottom plug. The top of the espresso cartridge may be sealed by a foil lid or the like, or be open and an adhesive attachable lid may be included for attachment by a user. A first method utilizes a hand held multi-function tool including a cartridge holder with a holder lid to capture the espresso cartridge, and a bottom tamper and plug seating arm. A second method utilizes a stationary base residing on a flat surface, a cartridge holder to retain cartridges on the base, and individual tools to fill and tamp brewing material in the cartridge, and to attach the bottom plug to the cartridge.

An arbor press includes a limiter for limiting load and/or travel of a ram used to press on an object. The ram includes a pair of pieces, a shaft and a sleeve, which are capable of relative translation, modulated by the spring. The spring may be preloaded, and configured to prevent overloading of the object, by limiting the transmission of force through the ram. The ram may also be configured to limit travel of the ram. The arbor press may include gearing to translate rotational movement of a handle to translational movement of the ram. The gearing may include a rack that is part of or is coupled to the shaft, and a pinion that is connected to the handle. Parts of the arbor press may be enclosed in a housing, to contain debris from metal-to-metal sliding in the arbor press, facilitating use in clean rooms.

Powder press having preferably stamps which are movable for a transverse press in a feed housing. The stamps partially delimit a hollow chamber of a matrix in the feed housing and are able to be coupled to a press device by one connector piece each. An adjustable positioning device, which is formed from a wedge arrangement having a stop surface and placed crosswise to the moving direction of the stamp, is allocated to the respective stamp for determining the pressing position thereof. The wedge arrangement includes at least one wedge which is adjustable crosswise to the moving direction of the stamp and has the stop surface which contacts a stop surface at the stamp. Such a wedge arrangement can achieve very accurate pressing positions of the stamp, and extremely stable positioning of the stamp to be pressed with high pressure.

A sealing pin includes a distal end portion that is inserted into the cylindrical body and that presses the sealant in the sealing step and a slit that is provided to allow the sealing pin to avoid the sensor element when the sealing pin is inserted into the cylindrical body, that extends through the distal end portion in a direction perpendicular to an axial direction of the distal end portion, and that has a width larger than a thickness of the sensor element.

A press device for manufacturing compacted tablets from at least one mixture in powder form, including at least one compaction assembly including a lower punch and an upper punch each having an active compaction surface and placed on either side of a die. The lower punch has a longitudinal recess open on the side of the die, inside of which is mounted a central rod which is translatably mobile relative to the lower punch. The central rod is coupled to the lower punch by a resilient link provided so as to hold, in an inoperative position, the central rod in a maximum deployed position in which the central rod protrudes relative to the active surface of the lower punch. The invention also relates to a specific compaction method and to a multi-layer compacted tablet with a recess.

The invention relates to a device (10) for producing a compression moulded body (11), having at least one first moulded layer, wherein the device has an upper ram arrangement (12) and a lower ram arrangement (13), with in each case at least one ram unit (15, 16), and a mould (14), wherein the ram unit has at least one ram tool (17), wherein the ram tools are configured such that they can be displaced axially with respect to one another in a die (19) of the mould, in such a way that moulding segments can be configured in the mould by means of the ram tools, wherein the device has a filling device (27), wherein the die can be filled with moulding material by means of the filling device, wherein the upper ram arrangement and the lower ram arrangement in each case have a multiplicity of circularly annually arranged ram units, wherein the mould is configured as a die plate (18) and, together with the ram units, configured as a rotor which is configured such that it can be rotated about an axis, wherein the device has a feed device (30), wherein a film (31) can be fed to the rotor by means of the feed device, such that it lies between a ram tool and a die which is configured in the die plate, wherein a layer can be configured on the first moulding layer by means of the film.

A tooling assembly, including a cermet tooling body and a plastic support structure operationally connected to the cermet tooling body. The plastic support structure at least partially encapsulates the cermet tooling body. The plastic support structure includes a plastic matrix portion and a plurality of high magnetic permeability metallic particles distributed throughout the plastic matrix portion. Each respective high magnetic permeability metallic particle has a magnetic permeability of at least 0.0001 H/m and each respective high magnetic permeability metallic particle has a relative magnetic permeability of about 8000. The plastic matrix portion is selected from the group consisting of high molecular mass polymers, thermoplastics, thermosetting polymers, amorphous plastics, crystalline plastics, resin-based materials, and combinations thereof.

A punch system or assembly includes a punch body and a punch tip or insert with a working end and a stem configured for selective engagement and disengagement within a cavity in the punch body. A latch mechanism which can be operated without tools is configured to engage the punch tip stem within the axial cavity in a closed position, and to disengage the punch tip from the punch body in an open position.

A system and method for the extraction of a material, wherein the system is configured for use with a press assembly and the extraction system includes a press ram, a pressure vessel for holding the material to be extracted, a filter, bottom hot plate and a cooling plate.
