Abstract: A centrifuge cage for coffee centrifuges or juice extractors is in two parts. The top part or member can be moved axially relatively to the bottom part between a closed position, in which the centrifuge cage is sealing tight along the boundary zone on its periphery, the same having a mesh zone, and an open position, in which the filtered material can be hurled outwards from the centrifuge cage.

Abstract: Disclosed is an improved basket filter which minimizes raw material waste and is formed of at least one rectangular perforated metal foil part folded along a bending line at its middle, transversely to its longitudinal edge, and at least two perforated metal foil elements in the form of sectors of a circle. The longitudinal edges of the rectangular metal foil part are connected to the straight line edges of the metal foil elements in the form of sectors of a circle so that, after assembly, the filter defines a round opening which merges into a straight line bottom edge. Adjoining edges between the rectangular metal foil part and the straight line edges of the metal foil elements are embedded in a plastic.

Abstract: This invention relates to a coffee filter comprising a drip catcher, a container and a filter insert designed to be introduced into the container, the filter insert comprising filter surfaces of a perforated metal foil and the container comprising a single outflow opening in its base.

Abstract: This invention relates to a permanently useable coffee filter comprising a funnel-shaped container, of which the base is provided with at least one outlet opening, and a funnel-shaped filter insert which is inserted into the container and of which the filter surface is situated at a distance from the wall of the container.

Abstract: A filtering device for the preparation of coffee, with a pot-shaped vessel, at the bottom of which a sieve sheet is attached, and with a water distribution plate, which is adapted to be supported by the upper edge of the vessel. The diameter of the water distribution plate is smaller than the inner diameter of the vessel, and a plurality of feet protrude from the edge of the water distribution plate nearly perpendicularly to the surface of the same. The free ends of the feet each form a shoulder, which serve to rest on the upper edge of the vessel such that the water distribution plate lies within the interior of the vessel and leaves a circumferential clearance to the same. Hot water which is poured onto the water distribution plate flows through that clearance onto the coffee powder. The water distribution plate may be removed from the vessel and laid onto a surface with its feet down as a base plate for the vessel, thus collecting water that might still pass through the filter.

Abstract: Electrodes utilized in various types of batteries are interconnected by means of a pair of conductive bands insulated from each other and bent into a zig-zag formation. Each conductive band overlays an electrode of one polarity, thus performing the function of separator as well as terminal conductor. Upon compression of the stacked electrodes into a housing, a compact battery is produced.
