  • Patent number: 5449364
    Abstract: A depilation apparatus comprising a number of pinching discs (39, 119, 143) which are coupled to a drive shaft (7, 145) by means of a coupling member (43, 123, 155) and which are pivotable by means of a pivot member (87, 89) about a pivot axis (115, 141) extending transverse to the drive shaft (7, 145) into a pinching position in which the pinching discs (39, 119, 143) exert a pinching force on one another near a depilation opening (3). The coupling members (43, 123, 155) are each provided with a rotund pivot guide (45, 125, 153), so that the pinching discs (39, 119, 143) are coupled to the drive shaft (7, 145) substantially without play in a radial direction in any position. In a special embodiment, the drive shaft (7) is provided with three parallel rods (11) and the coupling member (43) is arranged between the rods (11), whereby the coupling member (43) bears on each rod (11) with a lateral surface which forms part of a spherical surface tangent to each rod (11).

  • Patent number: 5112342
    Abstract: A depilator is provided comprising a housing which includes a skin-following surface for the skin to be depilated and at least one drivable hair pulling element rotatably mounted in the housing, the axis of the element being directed perpendicular to the skin-following surface. A first hair pulling element is arranged annularly while a second hair pulling element adjoins the inside wall of the first hair pulling element.

  • Patent number: 4678348
    Abstract: A radial bearing comprising a cylindrical bearing member and a shaft arranged therein, the member and the shaft being rotatable with respect to each other and one of the cooperating bearing surfaces of the member and the shaft being provided with a pattern of shallow lubricant-pumping grooves which, during relative rotation between the member and the shaft, build up a pressure in a lubricant present between the shaft and the member. In one axial zone of the member or the shaft the relevant bearing surface is provided along one half of its circumference with a groove pattern which is arranged to pump in one circumferential direction, and along the other half of its circumference with an identical groove pattern which is arranged to pump in the opposite circumferential direction.

  • Patent number: 4596474
    Abstract: A bearing system comprises two hydrodynamic bearings 5 and 7 by means of which two bodies 1 and 3 are rotatably supported relative to one another. Each of the bearings 5 and 7 has an inner and an outer pattern of helical grooves, which patterns in the direction of rotation for which the bearing system is intended build-up in opposite direction a pressure in lubricant. A reservoir 17 is situated between the bearings 5 and 7 and has two patterns 27 and 29 of feed grooves which pump lubricant towards the bearings 5 and 7 during operation.
