  • Patent number: 6524422
    Abstract: A method of manufacturing absorbent articles (17) in the form of sanitary napkins, panty liners or incontinence protectors for women, includes the step of cutting a web (5) of protective layer material with a sequence of pairs of cuts (8, 9) which are so spaced apart so that when the web (5) of protective layer material is placed on a web (1, 3, 4) of article blanks the two cuts (8, 9) in each pair of cuts in the sequence of pairs of cuts will lie linearly between the points of connection of flaps (23, 24) with the longitudinal edges of each article. The thus cut web (5) of protective layer material is then placed on the web (1, 3, 4) of article blanks and individual articles (17) are cut from the composite web (1, 3, 4, 5) in a second cutting step that defines the periphery of the articles.

  • Publication number: 20020170841
    Abstract: The present invention concerns a package for hygienic storage of two or more similar, non-folded, thin absorbent articles, preferably micro panty shields, which are placed on top of each other in a stack. The package is shape stable and shockproof and has a container part and a lid part. The container part and the lid part together delimit a storage space intended to accommodate the stack, where the storage space has a form that principally conforms to the form of the stack.

  • Patent number: 6481618
    Abstract: A transport box (1) formed from a blank of cardboard, corrugated board or like material, having a bottom section (2) with end flaps (3), atop section (4) with end flaps (5), and longitudinal side walls (6) with end flaps (7, 8), the end flaps forming at least part of an end wall. Each side wall has an upper part (6′) with an end flap (7) at each end, and a lower part (6″) with an end flap (8) at each end, the upper part (6′) being connected to the lower part (6″) via two folded-in edges (9, 10) which are parallel to the bottom section and form a fold. The edges are delimited by parallel fold lines (11, 12, 13), of which a first fold line (11) is situated between the first folded-in edge (9) and the upper part (6′), a second fold line (12) is situated between the second folded-in edge (10) and the lower part (6″), and a third fold line (13) is situated between the two edges (9, 10).

  • Patent number: 6449482
    Abstract: A method and apparatus for providing handoffs in a cellular communication system is disclosed wherein cells within the communication system share at least one transceiver unit or transceiver units from different cells are placed in close proximity to each other so as to create a larger overlapping region in which mobile stations can be handed off. The shared transceiver unit is able to transmit and receive radio signals with the communication frequencies assigned to the cells sharing the transceiver unit.

  • Publication number: 20020082579
    Abstract: In the continuous manufacture of absorbent articles (17) in the form of sanitary napkins, panty liners or incontinence protectors for women, the invention provides a method of providing said articles with protective layers (25, 26, 27). According to the invention, a web (5) of protective layer material whose width corresponds at least to the greatest width of the article (17) in the machine direction (M) is provided with a sequence of pairs of cuts (8, 9) which are so spaced apart that when the web (5) of protective layer material is placed on a web (1, 3, 4) of article blanks the two cuts (8, 9) in each pair of cuts in the sequence of pairs of cuts will lie linearly between the points of connection of the flap (23, 24) with the longitudinal edges of each article.

  • Patent number: 6363243
    Abstract: It is shown a locking arrangement at a portable device such as a telephone terminal. The device comprises a main body and a movable protruding member such as a flip-lid. The protruding member is switchable between at least a first position and a second position with respect to the main body. The locking arrangement comprises a plunger unit and a lock and release unit with a fixed part and a resilient part. The resilient part is resilient along at least one direction of resilience (X) away from the fixed part. The plunger unit is switchable, along a direction of insertion and retraction, between a disengaged position and an engaged position between the fixed part and the resilient part.

  • Patent number: 6138347
    Abstract: A conductive strap configured to attach to a circuit board containing a component sensitive to electronmagnetic interference (EMI) and to slidably contact an enclosure having a conductive internal surface can reduce or eliminate EMI in an electronic device. The strap is positioned on the circuit board to shield the sensitive component from EMI. Slidable contact between the shielding strap and the enclosure internal surface renders the strap suitable for almost any enclosure configuration without any design modification.

  • Patent number: 5274882
    Abstract: In a hinge mechanism, a first hinge portion and a second hinge portion are urged toward predetermined angular relationships relative to one another. A force, directed outwardly from the first hinge portion, is applied by an axle pivotally connecting the first and second hinge portions and having a V-shaped tip against a V-shaped groove in the second hinge portion, urging the V-shaped tip and groove to engage. In addition to being urged toward predetermined angular relationships, the first and second hinge portions are kept in predetermined angular relationships until a torsional force is applied to one of the hinge portions to overcome forces keeping the V-shaped tip and groove in engagement.
