  • Publication number: 20230368942
    Abstract: A sealed cable assembly includes a jacket enclosing a plurality of insulated wires. Each insulated wire includes a bare wire covered by surrounding insulation, and a cable plug or connector is electrically connected with the bare wires. A sealant surrounds the insulated wires in an air gap between the jacket and the insulated wires in a location at or near the cable plug or connector, and the sealant fills the air gap at the location to prevent or reduce fluid loss through the cable in an immersion cooling system. The cable assembly can also be sealed at an in-between section away from the cable plug or connector. The cable assembly is wrapped with a weatherproof film or tape at the location of the sealing to further prevent or reduce fluid loss through the cable.

  • Publication number: 20220381964
    Abstract: Polyester copolymeric materials include 40 to 51 mol % substituted naphthalate units, such as dimethyl-2,6-naphthalene dicarboxylate units, 10 to 40 mol % ethylene units, and 10 to 40 mol % hexane units. The polyester copolymers can be used to prepare multi-layer optical films by coextrusion and/or co-stretching. The copolyester polymeric materials have desirable optical properties and permit thermal processing at lower temperatures.

  • Publication number: 20220366500
    Abstract: Methods and systems for digitally transforming research and developmental data for generating business intelligence data are described. The method performed by a data analytics system includes accessing research and developmental data from a data source and converting the research and developmental data into a machine-understandable format. The method includes analyzing the research and developmental data to obtain operational distribution of risk, uncertainties, and resource demand, via a mathematical engine. The method includes quantifying unit return on investment (ROI) based, at least in part, on research and developmental investment and operational deficiency and transforming research and developmental data for visualization, optimization, and distribution mapping of efficiency, productivity, and cost, via an analytical engine. The method includes forecasting emerging product opportunities and future new product sales via a predictive engine.

  • Patent number: 11203704
    Abstract: Hot melt processable adhesive compositions to mask electronic components include at least one block copolymer, at least one tackifying resin, at least one semi-crystalline polyolefin polymer, at least one plasticizer, and at least one anti-oxidant. The adhesive composition is a hot melt processable pressure sensitive adhesive composition that is thermally stable, such that the composition when disposed on a surface withstands heating to 260° C. without degradation or flowing, remains optically transparent, and after heating to 260° C. remains cleanly removable.

  • Publication number: 20200347276
    Abstract: A thermally conductive adhesive is provided. The thermally conductive adhesive includes a polyolefin block-containing copolymer, a tackifier, and a thermally conductive filler. The thermally conductive adhesive is a crosslinked pressure sensitive adhesive, plus exhibits a high elongation at break. Additionally provided are thermally conductive articles, including a thermally conductive adhesive on a substrate and a thermally conductive pad. A method of making a thermally conductive adhesive is also provided, including exposing a composition to radiation to crosslink the composition.

  • Publication number: 20200156355
    Abstract: Multi-layer films, and processes to make the films, that enable the delivery of a substrate featuring a peelable thin layer of low haze, amorphous, isotropic film with the desired properties of high modulus, high usage temperature, UV blockage, and toughness The films are made using a co-extrusion, co-orientation and annealing process to enable the delivery of a thin isotropic, UV blocking layer on top of a release layer and support substrate. These film constructions can be kept together during additional processing steps such as coating and converting. The release and dimensionally stable substrate layer can be easily removed once processing steps are completed.

  • Publication number: 20190137028
    Abstract: The invention relates to a method for preparing a pipe for a continuous spray lining process, the method comprising the following steps: providing an inflatable packer (3); providing an expandable sleeve (4) with a conformable backing layer (5) and an adhesive layer (6); wrapping the expandable sleeve around the packer with the adhesive layer facing the outside; inflating the inflatable packer until it reaches a first diameter (D1), wherein the first diameter is smaller than the inner diameter (d) of the pipe section, thereby expanding the stretching sleeve, inserting the inflated packer with the expanded sleeve into the pipe (1, 2) until it reaches the pipe section to be sealed; and further inflating the packer until it reaches a second diameter (D2), thereby further stretching the expandable sleeve; wherein the second diameter is reached when the expanded sleeve touches the inner diameter (d) of the pipe section.
