  • Patent number: 9751186
    Abstract: A battery-operated hand power tool, in particular an eccentric sander, includes at least one electronically commutated electric motor that acts upon an output shaft and that is configured to drive a working tool. The hand power tool further includes at least one motor housing part that accommodates the electronically commutated electric motor. The electronically commutated electric motor and the output shaft define a common first axis that is coaxial with the output shaft. At least one handle region of the hand power tool accommodates at least one set of electronics configured to energize the electronically commutated electric motor. The motor housing part and the handle region are disposed at an angle to each other. The working tool has a diameter that is between 75 and 150 mm, but preferably is between 115 and 125 mm.

  • Publication number: 20070141311
    Abstract: An elastic material that lowers extension tension over a given range without a significant impact on the retractive tension or stress relaxation. The elastic laminate includes a first set of elastic members attached to one or more substrates while the elastic members are stretched, and a second set of elastic members or an elastic film attached to the one or more substrates while the elastic members or film are stretched to a different extent than the first set of elastic members. Both the substrate(s) and one of the sets of elastic members or film are gathered when the other set of elastic members or film is relaxed. Also included is a method of making the differentially-stretched elastic laminate.

  • Publication number: 20070142813
    Abstract: A garment with a gasket flap that exposes an ever increasing area of higher coefficient of friction or grip zone in response to an increased load in the garment due to body exudates or the like. The grip zone has a coefficient of friction that is greater than the portion of the gasket flap initially exposed to the wearer's skin. The gasket flap may be positioned at various places in the garment to prevent slipping or the like.

  • Publication number: 20060247593
    Abstract: A stretchable absorbent article has a longitudinal axis, a lateral axis, a front waist region, a back waist region, a crotch region extending longitudinally between and interconnecting said front and back waist regions, a length, and a width. The absorbent article has a liquid impermeable outer cover stretchable in at least one direction and a liner in opposed relationship with the outer cover and stretchable in at least one direction. At least one of the liner and the outer cover has a width substantially equal to the width of the absorbent article along the length thereof. An absorbent structure is disposed between the liner and the outer cover and extends from the crotch region to at least one of the front waist region and the back waist region of the article. The outer cover is elastic and is configured to improve the fit of the absorbent article.

  • Publication number: 20060149204
    Abstract: A disposable absorbent article comprising a bodyside liner, an outer cover, and an absorbent core sandwiched between the liner and the outer cover. When exposed to liquid under a specific set of conditions, the absorbent core exhibits planar growth of at least about 15% in at least one of the longitudinal and transverse directions at one or more positions. In particular embodiments, such planar growth can deliver improved fit, donning, and/or accident-awareness characteristics to disposable absorbent articles.

  • Publication number: 20060069365
    Abstract: An absorbent composite has at least one first region and at least one second region. The first region includes an elastomeric polymer at a first concentration and at least one absorbent material, such as superabsorbent material, and the second region includes an elastomeric polymer at a second concentration. The absorbent composite can provide improved attachment within an absorbent article, such as a stretchable absorbent article, even after fluid loading, while maintaining suitable absorbent properties.

  • Publication number: 20050256474
    Abstract: An absorbent article generally has a longitudinal axis, a lateral axis, a front waist region, a back waist region, and a crotch region extending longitudinally between and interconnecting said front and back waist regions. The article comprises an outer cover stretchable in at least the lateral direction and a liner in opposed relationship with the outer cover and stretchable in at least the lateral direction. An absorbent structure is disposed between the liner and the outer cover and extends from the crotch region to at least one of the front waist region and the back waist region of the article. The article has an attachment zone and at least one non-attachment zone laterally adjacent the attachment zone. The absorbent structure is configured for improved lateral stretch distribution of the article.

  • Publication number: 20050256488
    Abstract: An absorbent article generally has a longitudinal axis, a lateral axis, a front waist region, a back waist region, and a crotch region extending longitudinally between and interconnecting the front and back waist regions. The absorbent article has an outer cover stretchable in at least one direction and a liner in opposed relationship with the outer cover and stretchable in at least one direction. An absorbent structure is disposed between the liner and the outer cover and extends from the crotch region to at least one of the front waist region and the back waist region of the article. The absorbent structure has at least one weakening element disposed therein for reducing the resistance of the absorbent structure to stretching in a direction that defines an angle relative to the lateral axis of the absorbent article of greater than zero degrees and less than 90 degrees.

  • Publication number: 20050008827
    Abstract: In a substrate having a graphic and a method for applying the graphic thereto, a non-phosphorescent material is applied to the substrate to define a non-phosphorescent region of the graphic and a phosphorescent material is applied to the substrate to define a phosphorescent region of the graphic. At least a portion of the non-phosphorescent region and at least a portion of the phosphorescent region are in overlapping relationship with each other so as to define an overlapping region of the graphic. When the overlapping region is exposed to light sufficient to cause phosphorescence of the phosphorescent region the at least a portion of the phosphorescent region phosphoresces to render the overlapping region visible in the absence of light. In another embodiment, the graphic has a non-photoluminescent region in overlapping relationship with a photoluminescent region.
