A mechanism applies necessary forces for the creation of one or more plugs of compressible material to be supplied to a reactor. The plugs are capable of forming a seal between inlets for the plugs and the reactor. The mechanism includes two double-acting hydraulic piston cylinder assemblies coupled with two single-acting hydraulic piston cylinder assemblies.

A briquetting machine for loose metal scraps comprises a pre-extrusion part, a re-extrusion part and a final pressing part. On the upper portion of a pre-extrusion cavity (14) of the pre-extrusion part, a pre-extrusion releasing area (15) is formed near to one side of a re-extrusion cavity (24). At the front end of a re-extrusion plunger (23) of the re-extrusion part, a lateral gap (28) is formed near to one side of the pre-extrusion cavity. The cross section of the lateral gap is a right-angled trapezoid and the lateral gap is provided with a lateral slope (29). A briquetting method for loose metal scrapes is disclosed. By way of pre-extrusion and step-by-step feeding and triggering resetting loading, not only is a certain pre-pressing effect guaranteed while the loose metal scraps are processed in each feeding and pre-pressing step, but also the stress can be transferred and released timely under the over-pressure condition, which avoids the formation of dense metal block under the over-pressure condition. Therefore a continuous, automatic and safe pressing operation is assured.

A receiving and handling mechanism includes: an insert opening; a supply channel for passing the container to a handling device of the mechanism which is driven by a drive and is configured to handle the container; and an outlet. A rechargeable battery powers at least the drive of the handling device. The battery is powered by an external energy source, e.g. a renewable energy source. The method includes: predicting an availability of the external energy source, e.g. a source of solar energy; and adapting the operation of the device based on the predicted energy availability, so as to decrease the energy use of the device in case of a lower predicted energy availability and to increase the energy use of the device in case of a higher predicted energy availability.

A reverse vending machine is provided that includes an interface cabinet having an inlet portal. At least one bin is provided for receiving the accepted recyclable container. A roller system identifies and sorts the recyclable containers. A crusher is driven by a motor with a mechanical coupling between the crusher and the motor. The crusher is adapted to receive various containers and is positioned intermediate between the roller system and the bin. A cart or frame displaceable relative to the interface cabinet, the crusher is mounted on the cart or the frame. A reverse vending machine in another embodiment includes an interface cabinet, the interface cabinet having an inlet portal for recyclable container input and a rejected container depository. At least one bin and a roller system are provided along with a wash system for cleaning components of the interface cabinet between the inlet portal and the bin.

A pressure roller for an apparatus for compaction of empty (disposable) hollow bodies (beverage containers), particularly plastic bottles or tin cans, having at least one rotating roller that is disposed at a distance from a counter-bearing, forming a gap, has an essentially cylindrical mantle surface that possesses multiple profiled partial regions of the same type and the same width in its working region, following one another in the axial direction. These profiled partial regions are separated from one another, in each instance, by a circumferential recess. Each of these profiled partial regionsviewed axiallyhas multiple sections that follow one another. At least one cam-shaped projection that projects radially away from the mantle surface is disposed in one of these sections.

A compacting apparatus (1) for compacting receptacles has at least one advancing device (2) for conveying a receptacle (G) in a conveying direction (E) to an exit opening (6) of the compacting apparatus (1). The at least one advancing device (2) is configured to act on the receptacle (G) for compacting during conveying. A flap device (5) has an adjustable retaining flap (50) that closes the exit opening (6) in a closed position so that a receptacle (G) conveyed against the retaining flap (50) by the at least one advancing device (2) is retained on the retaining flap (50). The retaining flap (50) is adjustable out of the closed position to release the exit opening (6).

Container compressing arrangement, mountable in a reverse vending machine, for compacting empty containers, in particular beverage bottles or cans which are preferably made of plastic or metallic material, such as PET or tinned metal, the container compressing arrangement including: a first and a second rotatable roller, each of the rollers having a working surface arranged between two oppositely arranged ends, wherein the rollers are arranged adjacent to each other to rotate in opposite directions around a respective rotation axis in a common geometrical xz-plane; and wherein the working surface includes a plurality of ridges extending across the working surface, in an axial direction of the roller, and distributed in the circumferential direction of the working surface, each ridge having a longitudinal extension in the axial direction.
