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 an air directing device for a hair dryer for acting upon the air stream exiting from the hair dryer, in which an air directing member (10) is configured as a substantially tubular body (12) having an inlet opening (14) and an outlet area (16) for the air. The air outlet area (16) comprises a plurality of individual orifices (18) configured and positioned such that the exiting air stream is split into a plurality of substantially independent free jets.
Abstract: The invention is directed to an air-moving pulsator (12) for an electric hair dryer (10) which, for the purpose of creating a pulsing action in the air stream, includes a rotor (20, 41) rotatably supported in a substantially tubular housing portion (13) and having an impeller (11) adapted to be impacted by the air stream exiting from the hair dryer (10), wherein there is arranged upstream of the rotor (20, 41), as seen when looking in the discharge direction of the air stream, a stator (38) provided with selectively moveable vanes for varying the pulsation frequency and adapted to impart rotation to the air stream about its axis. In a preferred embodiment, stator (38) is provided with air-directing blades (28) pivotally mounted on radially oriented spokes (26), and the air-directing blades (28) carry cam follower pins (31) at the ends of arms (29). A cam ring (32) is rotatably secured by outer ring (33) on the housing portion (13) and has helical camming slots (36) to cam the pins (31).
Abstract: The invention is directed to a hair styling implement adapted to be attached to an air outlet opening of a hair dryer and equipped with a housing and a plurality of hair pickup elements and an adjusting element that is movable relative to the housing. In this arrangement, at least one locking member is provided which is adapted to be located in at least two positions; in a first position, the adjusting member is lockable with the housing, and in a second position in which the hair styling implement is attached to the dryer, the housing is lockable with the hair dryer.
Abstract: The invention is directed to a cleaning device 5, with a cradle structure 7 receiving the shaving head 3 of a shaving apparatus 1, as well as at least one cleaning fluid container 6, 61 and a device adapted to be driven by a motor 28 for feeding the cleaning fluid, wherein the cradle structure 7 receiving the shaving head 3 is arranged separately from the cleaning fluid container 6 and is supplied with cleaning fluid from the container.
Abstract: A filter for the filtration of extraction beverages includes a disk having a plurality of apertures through which the beverage extracted from the material to be extracted passes form the afflux side to the efflux side. Each aperture is formed by cut edges in the disk and by bending a cut edge away from the surface of the disk to form a roof-shaped dome. The filter is formed by a single punching, bending and embossing operation without scrap slug being produced.

Abstract: A dental cleansing implement having a thin, elongate shaft. The shaft includes a free end portion suitable in particular for insertion in the interproximal spaces and connected with a mounting portion or the like. The mounting portion is adapted to be coupled to an electric motor drive means of a handle member, and the cleansing implement is adapted to be rotated or oscillated about a shaft longitudinal center line. The free end portion of the shaft is made of a flexible material bent in the shape of a crescent, approximately.
Abstract: The invention is directed to a switched-mode power supply with a primary switched-mode flyback converter for the controlled supply of an electrical load from an input voltage source of optionally different voltage types and voltage levels, in which a series arrangement comprising of the primary winding of a transformer, the main current path of a a first controllable semiconductor switching device, and a first resistor is connected in parallel with the input voltage source. The secondary winding of the transformer is connected in series with a diode and the load. The base of the first controllable semiconductor switching device is connected to an arrangement that limits the maximum peak current of the first controllable semiconductor switching device in dependence upon the output current and that detects the voltage drop caused by the output current through the secondary winding along the internal impedance of the secondary winding of the transformer.
