Abstract: The invention is directed to a toothbrush having a brush section 20 comprising a bristle carrier 22 and bristles 24 fixedly secured thereto, with the brush section 20 being provided with components made of silver. Separate structures 28 are provided for fixedly securing the bristles 24 in their proper location in the bristle carrier 22, which separate structures 28 are made of a material with oligodynamic action.

Abstract: The invention is directed to an apparatus for treating the teeth and/or gums. This apparatus includes a treatment tool (1) for removing plaque in particular from the gum margin and/or for stimulating the gingival tissue. The treatment tool (1) is adapted to be set in vibration. For example, it is possible to generate the vibration by an unbalance structure (12) on a drive shaft (7) of the apparatus. The vibration results in a substantial improvement of the tooth cleaning and/or gum stimulating action.

Abstract: The invention is directed to an electric toothbrush having a brush section and a drive shaft received in the brush section. The brush section includes a first bristle supporting structure operatively coupled to the shaft for motion about an axis essentially perpendicular to a longitudinal axis of the shaft, and a second bristle supporting structure operatively coupled to the shaft for substantially transverse oscillating motion of the entire second bristle supporting structure relative to the longitudinal axis of the shaft. The first bristle supporting structure is generally cylindrically shaped and carries a plurality of bristle clusters.

Abstract: A brush section for an electric toothbrush includes a driver, a mounting tube which receives the driver, where the driver is arranged in the direction of a longitudinal axis defined by the mounting tube, a first bristle carrier mounted for rotation about a first brush axis, a second bristle carrier mounted for rotation about a second brush axis, and a mechanism to effect coupling engagement of the driver with the first and second bristle carriers. A motion of the driver effects a rotary motion of the first bristle carrier about the first brush axis and the second bristle carrier about the second brush axis. The first and second brush axes define an approximately right angle therebetween.

Abstract: The invention is directed to an interproximal brush for an electric toothbrush which is coupled to the shaft driving the bristle supporting structure in an alternating motion in a manner independent of the coupling of the bristle supporting structure to the shaft. The interproximal brush performs a pivotal motion enabling additional cleaning in particular of interproximal spaces.

Abstract: The invention is directed to a brush section for an electric toothbrush with a handle section comprising an electric motor, wherein the brush section is adapted to be connected with the handle section and has at its end remote from the handle section an essentially circular cylindrical rotary bristle supporting structure (38) on which bristles (48, 50) are arranged in the form of tufts (60, 62) of different lengths, and wherein the bristle supporting structure (38) has its axis of rotation at approximately right angles to a longitudinal center line of the brush section and is adapted to be driven in an alternating rotary motion over an arc of .+-.20.degree. to .+-.100.degree.. Some of the tufts (60) of bristles are serially located in position on a diameter and on an outer circular ring of the bristle supporting structure (38).

Abstract: In a first embodiment, a beverage brewing machine has a reservoir in which water is heated, which is arranged upstream of a brewing unit and heatable by an electric heating device. At the bottom is an outlet valve which opens only on reaching a given water temperature so that the hot water flows through an outlet pipe downstream of the outlet valve from the reservoir over the upper surface of a product, preferably ground coffee or tea-leaves, contained in a brewing unit, from which it goes to a receptacle as a beverage after extraction of the product. Hot water from the reservoir can also be taken via a pipe along paths other than over the upper surface of the product into the receptacle. The pipe takes a siphon-like path, the vertex of which is far enough above the bottom of the reservoir so that hot water also flows via the pipe to the other path and not only over the upper surface of the product only when a certain level is reached in the reservoir.

Abstract: A beverage brewing machine including a reservoir for holding cold water, an electric heating unit which during operation heats the cold water to produce a brewing water, and a brewing unit. The brewing unit has a receiving chamber for receiving a filter insert into which product is placed. The filter insert has a water-permeable wall. The receiving chamber has a collecting groove which receives water and delivers the received water to the outside of the water-permeable wall when the filter insert is resting in the receiving chamber so that water flows through the sidewall into an upper portion of the product in the filter insert. The reservoir includes a first water outlet through which a portion of the brewing water is delivered onto the top of the product in the filter insert, and the reservoir includes a second water outlet through which another portion of the brewing water is delivered to the collecting groove and from there through the water permeable wall of the filter insert.
