  • Patent number: 8312592
    Abstract: The invention relates to a cleaning apparatus (10) for releasing and transporting particles away from an area to be cleaned, comprising: a housing (6) having an opening (8) to be positioned on an area (1) to be cleaned;—a member that is movable within the apparatus for generating an airflow to release and transport particles away from the area; wherein the member comprises an airflow-generating surface (12) arranged within the housing (6), said airflow-generating surface in its operating condition lacing the area (1) to be cleaned and having a direction of movement that is substantially parallel to said area so as to cause an airflow parallel to said area. The apparatus according to the invention requires less energy for releasing and transporting particles away from an area to be cleaned.

  • Patent number: 6089239
    Abstract: The invention relates to a hair dryer/styler having a diffuser with elongated fingers. In order to obtain a comfortable contact between the fingers and the scalp and a better individual adaptation of the fingers to the scalp during use of the hair dryer/styler, the fingers are arranged, individually or in a number of small groups, on resilient means. Preferably, each finger is arranged on one resilient arm.

  • Patent number: 6085421
    Abstract: A shaving apparatus having an external cutting member and an internal cutting member, which is rotationally drivable with respect to said external cutting member, which external cutting member is formed with a circular groove having a bottom wall and an upright inner and outer wall, the bottom wall and the outer wall having at least a plurality of slit-shaped hair-entry apertures oriented substantially radially, the inner wall and a small part of the adjoining bottom wall further forming an uninterrupted guard wall which precludes the entry of hairs. To improve the hair-catching performance the guard wall has grooves which are oriented substantially radially and which are disposed in line with the slit-shaped hair-entry apertures.

  • Patent number: 6061869
    Abstract: A vacuum cleaner with a suction nozzle which is coupled to a handle on which a user of the vacuum cleaner can exert a pushing or pulling force for moving the suction nozzle over a surface to be cleaned. The suction nozzle is provided with an electrical drive for exerting a driving force on the suction nozzle, such that the pushing or pulling force to be exerted by the user is limited.According to the invention, the vacuum cleaner comprises a detector capable of measuring the pushing or pulling force, exerted on the handle and an electrical controller for controlling the driving force as a function of the measured pushing or pulling force. The controller controls the driving force in such a manner, for example, that the measured pushing or pulling force remains substantially zero. It is thus possible for the user to move the suction nozzle effortlessly over the surface to be cleaned.

  • Patent number: 4759416
    Abstract: The invention relates to a weighing element for a weighing apparatus, comprising an elongated plate-shaped ceramic bending element (1) provided with strain-gauge transducers, one end (2) of the bending element being secured to a frame (6) of the weighing element, the free other end being secured to a torque lead-in arm (10), said bending element being supported by the frame and by the arm at a distance a from said one end and said other end, respectively. In order to increase the accuracy of the weighing element it is proposed to make the frame and arm supports (8, 13) resilient in the longitudinal direction of the bending element.
