摘要:
Step-index optical waveguides are made of multicomponent glass containing a core glass and an outer glass which entirely surrounds the core class. A fiber-optic cable for conducting electromagnetic radiation, contains at least one bundle of individual fibers which encompass the step-index optical waveguides that are made of multicomponent glass containing a core glass and an outer glass that entirely surrounds the core glass on the circumferential wall thereof. These step-index optical waveguides provide great transmission capacity for transmitting data while keeping the transfer characteristics sufficiently durable. Furthermore, the fiber-optic cable is resistant against physical and chemical environmental influences and be protected against radical ambient chemicals. These aims are achieved by the fact that the outer glass of the step-index optical waveguides is provided with a material composition which is largely free from chemical interactions with the core glass when the fibers are drawn and is chemically inactive towards the plastic jacket.

In a method for producing a termination of an optical fiber bundle, the optical fiber bundle is combined at one end in a crimping sleeve, and the crimping sleeve is introduced with the end of the optical fiber bundle into a compression device having a crimping tool which matches the end geometry of the optical fiber bundle. Advantageous effects are achieved by the fact that the crimping sleeve is compression molded over the end of the optical fiber bundle with a predetermined crimping force by the crimping tool, and in that the crimping force is regulated during the compression molding process depending on the material of the crimping sleeve. In this case, the compression molding process is begun, carried out and ended depending on the distance, time and/or force by a regulating unit.

An absorbent article is provided that comprises a front waist region, a back waist region, a crotch region disposed between the front waist region and the back waist region, a front waist end edge, a back waist end edge, a longitudinal axis extending from a mid-point of the front waist end edge to a mid-point of the back waist end edge, a first longitudinally extending side edge, a second longitudinally extending side edge, an exterior surface, an interior surface, a topsheet, a backsheet, and an absorbent core disposed between the backsheet and the topsheet. A portion of the front waist region and a portion of the back waist region are joined in a surface to surface relationship to form a pant comprising a first permanent side edge seam and a laterally opposed second permanent side edge seam. The first and second permanent side edge seams define an initial waist opening circumference and a pair of leg openings. The absorbent article comprises a first fastening component comprising a first fastening surface and a first attachment surface. The first attachment surface is disposed on the interior surface or the exterior surface of the absorbent article in the front waist region. The absorbent article comprises a second fastening component comprising a second fastening surface. The second fastening component is disposed on or forms a portion of the same surface of the absorbent article on which the first attachment surface is disposed. The initial waist opening circumference formed by the first and second permanent side edge seams is configured to be opened. The first fastening surface and the second fastening surface are configured to be refastenably engaged and separated with each other.

A disposable absorbent article may comprise a chassis comprising side edges. The side edges of the chassis may comprise folded side edge segments disposed in the front and back waist regions and cut side edge segments disposed in the crotch region. The chassis may further comprise a barrier attachment zone disposed between a side edge of the absorbent assembly and the side edge of the chassis. The barrier attachment zone may extend continuously from the front waist region through the crotch region to the back waist region and may form an area of attachment between the side flaps and the backsheet. The chassis may also comprise an elastic gathering member disposed between the side barrier attachment zone and the side edge of the chassis.

A strong, easy to use tab and slot fastening device suitable for use with disposable absorbent articles. The fastening device preferably includes a tab member and a slot member. The slot member has an inboard portion, an outboard portion and a slot. The inboard portion located laterally inboard of the outboard portion and the slot located between the inboard portion and the outboard portion. The tab member has a length, a proximal edge, a distal edge and a lip portion. The tab portion is passed through the slot of the slot member to engage the fastening device. Once passed through the slot, at least the lip portion of the tab member pivots such that it overlaps the outboard portion of the slot member to prevent the tab member from disengaging from the slot member.

Absorbent articles such as disposable diapers, incontinent briefs, diaper holders, training pants and the like, having elastomeric ear panels and a fastening system that provides the user with different options as to how the absorbent article may be fitted to and removed from the wearer. The absorbent articles allow the wearer to choose between conventional and pull-on diaper configurations, or combinations thereof, and properly and comfortably fit a large range of wearer sizes. Further, the absorbent articles can be pulled on and/or off as a pant. This feature is provided by the ear panels which maintain sufficient tension to hold the diaper on the wearer throughout the period of use without harming the wearer's skin, while providing enough stretch to allow the diaper to be pulled up or down over the wearer's hips. The fastening system is refastenable for convenience yet strong enough to maintain the diaper in a fastened configuration without becoming detached if the diaper is pulled on or off the wearer. The front ear flaps are folded such that at least a portion of each of the front ear flaps extends laterally inwardly from the longitudinal edge of the containment assembly and are releasably bonded in the folded configuration. The first and second closure members are disposed at an angel to the longitudinal and lateral centerline of the absorbent article.
摘要:
Aspects of the present disclosure involve new methods for using disposable absorbent articles having replaceable absorbent core components as a swim pant. Non-removable absorbent core components may be disposed in a chassis of the disposable absorbent article. The absorbent article may also include replaceable absorbent core components adapted to be selectively disposed in capillary liquid communication with the non-removable absorbent core component. Embodiments of such absorbent articles can be configured for use as a swim pant or diaper with relatively low absorbency by removing the replaceable absorbent core component. Removal of the replaceable core component may be done without having to remove the absorbent article from the wearer. In addition, embodiments of the absorbent articles can be reconfigured for use as a high absorbency diaper by reinstalling a replaceable absorbent core component without having to remove the absorbent article from the wearer.
摘要:
A disposable absorbent article adapted to be worn about a lower torso of a human body and having a chassis, a non-removable absorbent core component disposed in a crotch region of the chassis, and a replaceable absorbent core component disposed in capillary liquid communication with the non-removable absorbent core component. The replaceable absorbent core component may be removed and a like component may be substituted in place of the removed component without the removal of the absorbent article from the wearer. The replaceable absorbent core component may be disposed inside an openable chassis pocket, with access for its removal and replacement provided by an aperture in a backsheet, an openable end of an external pocket, or an openable end of an internal pocket formed at an area of a waist end edge where the backsheet and a topsheet may be separated. Additional replaceable absorbent core components may also be incorporated.
