  • Patent number: 5915754
    Abstract: A method of mounting an electronic power component to a cooling element includes finishing at least a bonding area of the cooling element with a finish for use during soldering, forming an indentation in the bonding area of the cooling element, placing adhesive in the indentation, attaching the power component to the cooling element using the adhesive, and thereafter soldering the power component to the cooling element. The finishing melts during soldering and the adhesive prevents shifting of the power component on the cooling element during soldering. Alternatively, the power component is attached to a printed circuit board by adhesive bonding prior to soldering.

  • Patent number: 5893715
    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.

  • Patent number: 5884404
    Abstract: An inner cutter for a shaving head provided with an outer cutter, of a dry shaving apparatus, the inner cutter including several cutter blades in parallel relative alignment which are formed by means of slots cut into an elongate bar essentially transversely to the bar longitudinal extent, with the ends of the slots being of an arcuate configuration and each cutter blade being provided with a wall thickness D diminishing from a vertex SP of an arcuate end of a slot in the direction of a crest line SP of the bar, wherein the reduction of wall thickness D, extending from the vertex SP, covers an area B which is greater than half the relative distance A of two adjacent cutter blades in the area of the crest line SL.

  • Patent number: 5875706
    Abstract: A food processing apparatus with a base unit (1) which has at least two separate mounts (2, 3), each for one processing bowl (4, 6), with one drive member (7, 8) positioned in the area of each of the mounts (2, 3) and being in driving connection with an electric motor, is equipped with a safety device. This safety device serves the purpose of ensuring that only one processing bowl (4) at a time can be mounted on the appliance in an operating position, while the safety device inhibits a second processing bowl (6) from being accommodated in the other mount (3). To accomplish this, a safety element (11) is provided which is adjustable between two blocking positions. When the safety element (11) is in the one position, the first mount (2) is rendered unable to accommodate a processing bowl while the second mount (3) is enabled to accommodate a processing bowl.

  • Patent number: 5867856
    Abstract: The invention is directed to a brush section (1) for an electric toothbrush which includes a mounting tube (2) in which a shaft (7) is received which is mounted so as to be rotary about a longitudinal axis (3) and is adapted to be driven in an oscillatory fashion. Further, the brush section (1) includes a bristle supporting structure (11) which is arranged so as to be rotary about a transverse axis (14) by means of a bearing pin (18) and is adapted to be set in a rotational motion (29) about said transverse axis (14) by means of a drive pin (24). The fixed connection between the bearing pin (18) and the shaft (7) has the added effect of causing the bristle supporting structure (11) to perform a pivotal motion (28) about the longitudinal axis (3). The rotational motion (29) of the bristle supporting structure (11) produces a cleaning action on a user's exposed tooth surfaces, whilst the pivotal motion (28) acts to accomplish an additional cleansing operation on the user's inter-proximal surfaces.

  • Patent number: 5868146
    Abstract: The invention is directed to a hair styling appliance and a method of styling hair, using in particular the hair styling appliance. The hair styling appliance is comprised of a handle portion, a heating portion (6) for heating the hair, and a pressure-generating clamp (8) for the generation of a contact pressure acting on the hair to be styled, the hair being adapted to be introduced between the heating portion (6) and the pressure-generating clamp (8). In this arrangement, a styling edge (10) is provided in the area of the heating portion (6) and/or the pressure-generating clamp (8) of the appliance, which styling edge has a cross-section of arcuate, in particular circular-arc shape, of polygonal or similar shape.

  • Patent number: 5862558
    Abstract: The invention is directed to a brush section (1) for an electric toothbrush which includes a mounting tube (2) in which a shaft (7) rotary about a longitudinal axis (3) is received. Further, the brush section (1) includes a bristle carrier (11) from which bristles (15) extend in the direction of a brush axis (14). The bristle carrier (11) is rotary about a transverse axis (19) by means of a bearing pin (21). By means of in particular a tapered disk (24), the brush axis (14) and the transverse axis (19) define between them an angle (28) departing from an apex (29). In operation of the electric toothbrush, the bristle carrier (11) performs a nutating motion about the transverse axis (19). This effects a revolving approaching/receding motion of the free ends of the bristles (15) resulting in an improved cleaning action on a user's teeth.

  • Patent number: 5850655
    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.

  • Patent number: 5842244
    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.
