  • Patent number: 6574400
    Abstract: A fiber optic cable (10) having a cable core (20) includes fiber optic cable components in the form of buffer tubes (23), a binder (26), and strength members (31). Cable core (20) includes a series of stripes (38) that comprise a mixture of adhesive and water absorbent substances. The water absorbent substance of stripes (38) is operative to swell and thereby block the flow of water in cable (10). Stripes (38) are made by the sequential coating of the adhesive and the water absorbent substances onto the cable whereby the water absorbent substance is propelled into interstices between the cable components. FIGS. 2 and 4.

  • Patent number: 6573026
    Abstract: A method of writing a pattern, such as a waveguide, in a bulk glass substrate. The bulk glass substrate can be formed from, for example, borosilicate or sulfide or lead glass. A pulsed laser beam is focused within the substrate while the focus is translated relative to the substrate along a scan path at a scan speed effective to induce an increase in the refractive index of the material along the scan path. Substantially no laser induced physical damage of the material is incurred along the scan path. Various optical devices can be made using this method.

  • Patent number: 6572723
    Abstract: A process for forming a multilayer composite insulator includes the steps of forming an insulator precursor by orienting an insulation insert in a desired location between a first facing layer and a polymer based blanket layer, applying differential heat to two opposing sides of the insulator precursor and applying pressure to the insulator precursor. Together, the applied differential heat and applied pressure mold the insulator precursor to a desired shape while also providing the polymer based blanket material with a first relatively high density adjacent a warmer of the two opposing sides and a zone of relatively low density adjacent the cooler of the two opposing sides. The process also includes the cooling of a molded precursor to set the insulator in the desired shape.

  • Publication number: 20030100111
    Abstract: A cell transfection apparatus and methods for making and using the cell transfection apparatus are described. The cell transfection apparatus has a surface on which there is printed at different locations one or more foreign biomolecules (e.g., DNA, RNA, oligonucleotides, nucleotides). The foreign biomolecules can be printed at the same time. The surface is then covered with a transfection reagent which is incubated and removed from the surface before cells in a cell growth media are placed on the surface. The surface is configured such that the cells which become transfected with one or more foreign biomolecules are segregated from the cells which fail to become transfected with one or more foreign biomolecules. There are disclosed two embodiments of the cell transfection apparatus.

  • Patent number: 6569507
    Abstract: A method of increasing the amount of entrained vapor in fiber-reinforced resin composite materials, and in particular filament wound composites, wherein a particularly effective chemical foaming or blowing agent is incorporated into the resin matrix composition used to form the composites. The foaming agent creates vapor-filled voids throughout the resin matrix of the composite as it cures. The superior composites containing these vapor-filled voids demonstrate high burst strength retention and excellent resistance to cyclic fatigue. The invention also relates to composite materials and articles thereof.

  • Patent number: 6568623
    Abstract: A moving strand is provided and a size is applied to the strand. A collet is rotated to wind the strand and build a package. The strand is reciprocated with a strand reciprocator to lay the strand at a wind angle on the package surface as the package rotates. A rotatable collet receives the strand to build a package. A strand reciprocator is mounted to guide the strand from edge to edge of the package and to lay the strand in a helical pattern on the package surface as the package rotates. The collet and the cam for the strand reciprocator are driven by motors. A collet inverter drive and a cam inverter drive control the rotational speed of the collet and cam, respectively. A controller is operatively connected to control the collet and cam inverter drives. A memory device such as a computer provides information to the controller of the waywind and wind angle as a function of package buildup time.
