Abstract: A tumbler includes a support frame assembly rotatably mounting a drum assembly for driving by a drive assembly comprising an electric motor drivingly connected to the drum assembly, a battery coupled to the electric motor, and a photovoltaic panel connected to the battery for charging it.

Abstract: The device comprises a drum drier with parallel streams (1) fed with recycled materials and a drum drier and countercurrent mixer (2) fed with virgin aggregates at its entry end (2a). The exit end (1b) of the drum with parallel streams (1) through which the dried and preheated recycled materials leave is connected to a ring (26) for introducing materials through the side wall of the countercurrent drum (2) through a chute for transferring the recycled materials. The ring (26) for introducing the recycled materials opens into a recycling and mixing zone (23) situated in the countercurrent drum (2) around the body of the burner (10), between the flame zone (22) and the mixing zone (24). The dried and heated recycled materials (8) are transferred continuously into the recycling zone (23) of the countercurrent drum (2).

Abstract: A toothbrush and brace cleaning kit is provided wherein an enlarged toothbrush head longitudinally aligned with a rearwardly extending handle includes a first bristle matrix orthogonally and fixedly mounted to a first surface of the head, wherein a second surface of the head is defined by a bifurcated, spaced parallel second surface defining a gap therebetween. The gap includes a bore construction to selectively receive one of a plurality of bristle tufts positioned below the upper bifurcated surfaces, wherein confronting spaced, parallel surfaces of the gap include aligned and confronting plural rows of flexible, planar brush elements for cleansing interiorly of an orthodontic brace assembly.
