  • Publication number: 20110263403
    Abstract: Absorbent article for men intended for single use and having longitudinal side edges, a rear end edge and a front end edge and comprising an inner liquid-permeable surface layer, an outer liquid-impermeable surface layer and an absorbent body arranged therebetween. The absorbent body tapers from a front end portion towards a rear end portion. During use, the article is intended to be arranged over the genitals of the wearer and to extend forwards with its wider end portion in the direction of the abdomen area of the wearer and to extend backwards with its narrower end portion a little way below the penis of the wearer. The article comprises an elastic element attached to the liquid-permeable surface layer along at least parts of the longitudinal side edges of the article. The elastic element is attached to the liquid-permeable surface layer along longitudinal edges lying opposite one another of the elastic element. A cut is arranged between the attachments in the form of a slit or cutout.

  • Patent number: 7446267
    Abstract: A transit device is disclosed for passing at least one elongate line sealingly through an opening in a wall. The device comprises a clamping frame and a number of blocks which together fill-out the frame. At least one of the blocks has a through-penetrating channel for receiving the line, wherein the block is adapted to permit lateral insertion of the line into the channel. The device also comprises a separate tubular bush made of elastic material. The bush has a generally axial through-penetrating slot in its wall, to enable the bush to be laterally fitted to the line, and has an outer cross-section which corresponds generally to the cross-section of the channel in the block. The bush comprises a plurality of radially separated layers which can be separated from each other so as to adapt the through-penetrating channel of the bush to the line.

  • Patent number: 7241241
    Abstract: A direction setting device has a frame and a rotatably mounted shaft which supports a first belt pulley whose rotational position defines a direction to be set. A rotary motor on the frame supports a second belt pulley, and an endless belt extends around the first and second pulleys. A deflecting device deflects a second part of the belt while the motor is stationary at a set position of rotation, so as to change the effective length of the second part of the belt. A resilient tensioning device changes the length of the a first part of the belt to compensate for the change in length of the second part of the belt. This enables the first pulley to be turned through an angle that is dependent on the deflection of the second part of the belt by the deflecting device.

  • Publication number: 20050119078
    Abstract: The present invention relates to a direction setting device comprising a frame (1) that carries a rotatably mounted shaft (2) which supports a first belt pulley (13) whose rotational position defines a direction to be set, wherein a rotary motor (71) carried by the frame supports a second belt pulley, and wherein an endless belt (14) extends around the first and second pulleys. A deflecting means (4, 41, 72) which functions to deflect one part (142) of the belt while the motor (71) is stationary at a set position of rotation, so as to change the effective length of the first part (142) of the belt; and further includes a resilient or springy tensioning means (5, 6, 16, 18) which functions in changing the length of the second part (141) of the belt to compensate for the change in length of the first part of the belt, thereby enabling the first pulley (13) to be turned through an angle dependent on the deflection of the first part (142) of the belt by the deflecting means.

  • Patent number: 6601309
    Abstract: A system for marking a corner angle in a working area with the aid of light planes, wherein a straight, elongate guide is disposed on each respective side of a planar working surface in the working area. Each guide carries a carriage that can be moved to chosen positions alongs its guide. Each carriage carries a laser unit which is adapted to emit a light plane that intersects the working surface, as well as the light plane of the other laser unit, at a chosen angle. Each laser unit is adapted to maintain its light plane in a set orientation relative to the longitudinal axis of its associated guide, regardless of the position to which the carriage has been moved along said guide, and both laser units are adapted to be activated simultaneously for marking said corner angle.

  • Patent number: 6499339
    Abstract: A method and an apparatus for determining the resiliency of a road surface include a vehicle (1) that is caused to move along the road surface (3) and that exerts a load on said surface with one wheel (2). A ball of plastic material (16) is shot onto the road surface (3) so as to adhere thereto in the movement path of two measuring arrangements (8, 9; 18, 19) which are separated in the direction of movement of the vehicle (1) and by means of which the vertical distance is measured between the upper side of the ball (16) adhering to the road surface (3) and a vehicle-carried reference in two positions along the vehicle. The distance between the reference and the measuring body can be established in several positions along the vehicle (1), for determining the deflection curve of the road surface.
