  • Patent number: 4079739
    Abstract: A die-cut, contoured, catamenial napkin of joined-together layers of sheet material assembled into a sandwich which combines a thin, soft, flexible peripheral portion for comfort with a thick central portion for increased fluid-holding capacity. The uppermost layer is a thin batt of intermingled fibers provided with unbonded low density cushion areas separated by spaced bonded areas comprised of compressed fluid-distributing channels of higher density extending generally longitudinally of the batt and intersecting the ends and edges. The central portion of the uppermost layer is upwardly deformed to provide a pad-receiving cavity in which a main fluid-holding element consisting of a relatively thick pad of absorbent material is positioned in intimate physical contact with the uppermost layer while the horizontal face portions of the side and end walls of the central pad are free of contact with neighboring components.

  • Patent number: 4076018
    Abstract: A magnifying lens incorporated in an endoscope optical system for viewing an illuminated area to be examined by means of the endoscope is adjustable between end positions in which it lies behind and in front of the focus of the optical system respectively, whereby to enable general examination of said area at a relatively small magnification and a more detailed examination of said area at a relatively higher magnification. A viewing window of an endoscope optical system is heated by an electrical heating conductor to guard against clouding of the viewing window, for example by the breath of a patient.

  • Patent number: 4068665
    Abstract: An improved diaper fastener system has particular application to a disposable diaper having a generally rectangular-shaped absorbent pad or filler disposed between a fluid-permeable cover sheet and a thermoplastic film backing sheet. The fastener system is comprised of a pair of pressure-sensitive fastening tapes incorporaing a standard release liner with each tape. The improvement includes anchoring one surface of the fixed portion of the fastening tape of the bottom surface of the cover sheet and then adhesively bonding the other surface of the fixed portion to a folded-over side marginal portion of the backing sheet. The release liner is positioned atop the cover sheet and extends laterally a distance that corresponds with the lateral dimension of the attachment portion of the tape.

  • Patent number: 4067338
    Abstract: An improved diaper fastener system has particular application to a conventional disposable diaper having a generally rectangular-shaped absorbent pad or filler disposed between a fluid-permeable top cover sheet and a thermoplastic film backing sheet. The fastener system is comprised of a pair of substantially conventional pressure-sensitive fastener tapes but having stress-accepting inserts traversing a certain distance between the release liner and a position on the fixed portion of the fastener tape. When the attachment portion of the tape is opened for use, the applied forces are at least partially accepted by the stress-accepting insert, transferring it through the release liner to the cover sheet which is stronger than the plastic film backing sheet.

  • Patent number: 4066081
    Abstract: A disposable diaper comprising, an absorbent pad assembly having opposed surfaces and a side edge. The diaper has a tape fastener comprising, a pressure-sensitive tape strip having a first end portion secured to one of the surface of the pad assembly adjacent a side edge, a second securement end portion for securing the diaper about an infant, and an elastic band extending around and laterally constraining a central portion of the strip intermediate the first and second portions. The band reduces the lateral dimensions of the central portion and the effective normal length of the strip, such that the second strip portion is longitudinally extensible relative the first portion by increasing the size of the central portion from reduced to enlarged lateral dimensions while expansing the band responsive to forces applied in a longitudinal direction against the strip.

  • Patent number: 4063559
    Abstract: A disposable diaper is provided with adhesive tab fasteners having a fixed end secured to the diaper and an extendible free end. A pressure-sensitive adhesive coating is provided on one face of the free end and a partible protective cover means is permanently attached to the adhesive coating. The protective cover is substantially coextensive with the adhesive coating when the free end is in a non-extended storage position, but is parted when the free end and adhesive coating are extended to a working position, thereby making portions of the adhesive coating available for use in securing the diaper about an infant. The size and spacing of the exposed adhesive portions on the free end can be controlled to provide adequate adhesive contact for securing the diaper about the infant, while at the same time providing a free end that can be separated from the diaper after affixation for inspecting or repositioning the diaper, and thereafter refastening the diaper.

  • Patent number: 4057053
    Abstract: A foot massager and bath is disclosed in which either a massage or a heated bath or both are optionally available to the user. The bath is maintained in temperature by an element protruded through the wall of the unit to provide a metal-to-bath heat exchange and is shielded from the user's feet by a grille portion of the unit. A vibrating massage is provided by an electrical vibrator mounted on a plane above the plane of the deck upon which the feet are rested and which is coupled to the deck at a point substantially below the foot plane to provide a variable-direction motion of the foot plane area and a consequent variation in the vibrations imparted to the feet. A variable-capacity mount is disclosed which supports the unit on a surface by means of a variable-contoured elastomeric support under differing weight circumstances to provide increased stiffness in the support to accommodate an increased load from within the unit.

  • Patent number: 4056103
    Abstract: An improved wrapper structure for tampons containing superabsorbent material. The wrapper provides the used tampon with a fluid-lubricated surface to ease withdrawal. The wrapper is a fluid-permeable web material having a saline fluid retention capacity sufficient to partially counteract the high capillary suction pressure exerted by superabsorbent fibers in the tampon core and thereby retain enough fluid in the wrapper during use to maintain the surface fibers of the wrapper in soft, lubricous condition.
