A device is described wherein an actuator (3, 4; 103, 104) drives a member, such as a rack (6) meshed with a pinion (5), between two stable positions. For this purpose, elements for stopping the movable member are provided, which cooperate with elements present on the outer housing (2, 21), in which the actuator and the movable member (5, 51) are arranged, for holding at least one of said stable conditions. The device of the invention ensures low energy consumption because the actuator (3) only operates for moving the movable member from one stable position to the other.

The invention relates to a coffee tamper. More specifically, the invention relates to a device for tamping coffee grounds in a basket or portafilter of an espresso machine, by which device a reproducible pressure is applied to the coffee grounds and which is designed to reduce occupational-related diseases among professional users, like e.g. baristas.

A refuse collection apparatus is disclosed. A refuse collection apparatus according to one embodiment of the present invention a main body unit into which a refuse is inserted, a refuse compression unit installed in the main body unit and configured to compress the refuse inserted into the main body unit and a movement range detection unit located inside of the main body unit and configured to detect a movement range of the refuse compression unit.

An impact forming device and method for local small features on a metal thin-walled curved-surface part. The impact forming device includes impact forming dies, impact loading units and a forming supporting die, wherein the impact forming die is provided with an impact forming part, and the impact forming part is a convex part corresponding to a local small feature; the forming supporting die can support and fix a metal thin-walled curved-surface part without forming local small features, and the forming supporting die is provided with concave parts matched with the impact forming parts; and the impact loading unit includes a guide rail, an explosive ball and a detonating block, under the impact loading of the impact loading units, the impact forming parts can impact the metal thin-walled curved-surface part without forming local small features under the matching action of the concave parts to form the local small features.

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.

A punch and die holding apparatus comprising a die block having a bottom die plate defining a die recess and forming a die clamp, a top die plate defining a guide tube cavity, the bottom die plate and top die plate defining a punch receiving gap, a die plate clamping bolt, and a plurality of gap opening stops. The punch and die holding apparatus has a punch holder having a guide tube, a collet chuck at least partially inserted within the guide tube, a collet inserted within the collet chuck, and a punch having a first end comprising a stem, a second end comprising a punch protrusion, and a central portion, the punch stem configured to be inserted into the second end of the collet; and a die received within the die recess.

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 may 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.
