Abstract: By means of a holder for a roll of unwindable material, in particular a holder for paper rolls, preferably for standing a paper roll vertically on a horizontal surface, with a cylindrical holding, rod (1), a base (5) and an essentially known pivotal retaining arrangement for the free end of the paper roll, the object is to provide a holder in which the roll is retained on the holder in a stable manner also when different widths of paper are used, and where the cost of manufacture can be reduced through a simple embodiment and few components. This object is realised by the retaining arrangement (2) being pivotally attached to a detachable cover (3) that moves along the axis of the holding rod and which is equipped with a cylindrical skirt (4) that likewise moves axially along the holding rod, and where the diametrical dimensions of the cover are such that during application the cover is in contact with the end surface of the paper roll currently in use, and covers it at least partially.

Abstract: A plug for a power consumer is positioned centrally in a recess in a bottom of the power consumer and rests in a flange at an edge of the recess. The plug has a first portion and a second portion that can be rotated relative to each other about a common axis perpendicular to the bottom. The first portion of the plug has a plurality of fish plates extending outwardly from its sides, each fish plate having a recess. The second portion has a plurality of hooks, each having a protuberance. By rotation of the second portion relative to the first portion the protuberance of each hook is engaged in the recess of the respective corresponding fish plate.

Abstract: With respect to a filter with a fastening device for a coffee-making apparatus of the type where water is brought to a boil in a closed container, whereupon the water is pressed through a riser pipe into a funnel, where boiling water extracts aromas and flavour from the ground coffee, whereupon the finished coffee beverage is filtered back into the closed container through a filter placed at the outlet of the funnel, where the filter is fastened by means of a fastening device which reaches through the riser pipe, the objective is to to provide a filter where the aroma and flavour of the ground coffee is exploited as well as possible and where the filter offers a comparatively large filter surface for the finished coffee, and where the filter can easily be removed from the funnel and cleaned with a view to further coffee-making. Moreover, the filter must be easily replaceable by dismantling the handle and locking clip and fitting these on a new filter.
