  • Patent number: 4680450
    Abstract: A heating apparatus at the end of a diaper production line composed of a series of radiant energy sources. These radiant energy sources are controlled so as to emit differing concentrations of radiant energy. The sources are controlled so as to emit radiant energy more absorbent by diaper polymer backing sheets in the first section of the heater and more absorbent by heat-shrinkable diaper elastics in the downstream portion of the heater. Further, the temperature of the heaters is preferably controlled to the desired infrared range by blowing hot air past the heaters and onto the diapers so as to provide conductive transfer and at the same time control the infrared radiant energy that is provided by the heaters.

  • Patent number: 4655761
    Abstract: The invention relates to a system for fastening refastenable garment such as diaper or incontinent garment in which a tape and polymer backing material for the garment are provided such that tape may be removed after refastening to the diaper without tearing of the polymer material. The system of the invention utilizes a polypropylene tape material that is embossed on the outer surface and smooth on the adhesive-carrying surface. The adhesive on the tape is a semihard adhesive that provides high adhesion values to the polymer that nevertheless may be peeled free for removal of the tape and subsequent refastening. The polymer forming the outer backing if the diaper is a relatively thick, embossed polymeric sheet. In the refastenable system of the invention the strength and adherence of the tape to the strong, embossed polymer backing sheet is controlled so as to achieve secure fastening with release of the adhesive from the embossed sheet without tearing.

  • Patent number: 4655757
    Abstract: The invention generally provides for formation of meltblown material containing wood fiber on to a continuous foraminous belt. During formation a polymer and wood fiber first layer is applied to a moving belt from at least one bank of meltblown forming apparatus. This first layer does not contain superabsorbent. The belt carrying the first layer passes beneath at least one further source of meltblown fiber into which superabsorbent is added along with the wood fibers. This provides at least one additional layer integrally connected to the first-formed layer and having superabsorbent properties. The first layer acts to aid in trapping of any superabsorbent which is not immediately entangled in the meltblown and wood fibers and prevents it passing through the forming belt.

  • Patent number: 4648513
    Abstract: The invention is generally accomplished by providing a sheet of cover material, folding the sheet such that one portion to become the front extends up to a line slightly below the edge of the portion to become the back. The flap of the back portion extending above the front is coated with adhesive; the disposal container is formed by sealing the sides of the folded sheet. Outward of the seal lines that form the container are placed tear lines such as perforation lines. The object to be wrapped then is placed onto the exterior side of the front of the container, and the container is wrapped around the object and sealed with the adhesive strip on the flap to form a package. The ends of the package are then sealed. The package may be opened by tearing at the perforations and unrolling the container by releasing the adhesive flap to recover the wrapped article.

  • Patent number: 4642151
    Abstract: The invention provides an efficient method and apparatus for applying linear segments of elastic to a base material transverse to the direction the base material is moving in a production line. This object is obtained by providing an apparatus with means for sequentially and repeatedly gripping an elastic strip, pulling that elastic strip across the base material, and then releasing the elastic strip. At about the same time the elastic strip is released, it is cut to size. Also at this same time, the elastic strip is brought into contact with the base material. Preferably, the elastic strip is brought into contact with the base material by virtue of rotation of the gripping, pulling and releasing means.

  • Patent number: 4399877
    Abstract: In situations where it is necessary to directionally drill boreholes from the surface in a substantially horizontal attitude, such as for pipeline river crossings, the precise directional parameters of drilling become critical. A system of tools for efficiently accommodating the precise directional steering of the drilling includes a continuous electrical communications path within a drill string, which path provides steering data at the surface for controlling the drilling operation. A side entry sub is positioned in the tool string at its upper end. A cable system is employed in each pipe section placed in the string and includes provisions for breaking and making connections with the cable without withdrawing the cable from the pipe string. A steering tool is fixedly positioned in the drill pipe near the drill bit and is not normally withdrawn from the hole except with the drill bit.

  • Patent number: 4393598
    Abstract: A surface activated multishot survey tool utilizes a dampened magnetic compass movably positioned within a probe to determine the direction of a borehole. Lamps in the probe are operable to light the face of the compass. A lens projects the image of the compass onto a movable film strip. An electrical cable is connected to the probe and is used to pass a current to the lamps and provide selective operation of the tool from the surface of the borehole. Electrical connectors are provided at each end of the probe so that the probe may be inverted within the borehole to accommodate surveys in which the angle of the borehole is greater than that at which the compass will operate without error. Because connectors are located at both ends of the probe, electrical current passes around the magnetic compass, thus creating a magnetic field about the compass.
