Utilizing Special Inert Gaseous Atmosphere Or Flushing Mold With Inert Liquid Patents (Class 264/85)
  • Patent number: 11352476
    Abstract: A method of making a foamed article, for example a foamed component for an article or footwear, comprises forming a structure of interconnected, unfoamed, thermoplastic polymeric members spaced to define openings between the thermoplastic polymeric members. The structure may be made by printing a thermoplastic polymeric material with a three-dimensional printer. The thermoplastic polymeric members are heated to a first temperature to soften the thermoplastic polymeric members and the softened thermoplastic polymeric members are infused with at least one inert gas at a first pressure greater than atmospheric pressure. The first pressure is sufficient to cause the at least one inert gas to permeate into the softened thermoplastic polymeric members. After being infused with the inert gas, the pressure is reduced to at least partially foam the thermoplastic polymeric members.

  • Patent number: 10647614
    Abstract: Cutting elements include at least one metal diffused into interbonded grains of diamond. Earth-boring tools include at least one such cutting element. Methods of forming cutting elements may include forming a mixture of the at least one metal salt and a plurality of grains of hard material and sintering the mixture to form a hard polycrystalline material. During sintering, the metal salt may melt or react with another compound to form a liquid that acts as a lubricant to promote rearrangement and packing of the grains of hard material. The metal salt may, thus, enable formation of hard polycrystalline material having increased density, abrasion resistance, or strength. The metal salt may also act as a getter to remove impurities (e.g., catalyst material) during sintering. The methods may also be employed to form cutting elements and earth-boring tools.

    Abstract: In the tube manufacturing industry, five general methodologies for manufacturing tubes are known at this time. The first is under an extrusion of molten metal by means of a press. The second is by means of a rotary lamination system known as “Piercing” or “Mannesmann”. The third is the welded pre-tube that is obtained from a laminated strip. The fourth, known as the “Cast & Roll” system, whereby a pre-tube, obtained directly from the melting, is laminated by a triple roller system. Finally, the innovative manner whereby a continuous vertical casting manufactures pre-tubes continuously, directly from the melt. The four first systems are widely used in the industry to manufacture what is known as a “pre-tube” that usually has a diameter of 60 mm or higher, which we shall name “old pre-tube”. Different processes are applied to that old pre-tube to bring it to smaller diameters and thicknesses finally required by the market.

    Abstract: In a process for the preparation of inorganic sample disks for analysis, the sample, in powdered form, is mixed with a powdered reagent flux which has been pre-melted. In an inert gas atmosphere, the mixture is placed in a graphite crucible and heated to a temperature slightly above 1000° C. After the flux dissolves the sample, a homogenous mix is produced. This mix is then poured into a graphite mold, the bottom of which contains a molten pool of an inert metal, such as gold, which acts as a smooth receiving surface. Upon cooling, the material in the mold solidifies, resulting in a glassy disk that can be analyzed. Cooling can be accelerated by making use of a cooling fluid that has a substantially higher thermal capacity than air.

  • Publication number: 20130032965
    Abstract: Disclosed is a method for hot isostatic pressing a substrate. At first, a metal container is provided. Powder is filled in the metal container before the metal container is located in an oven. The metal container is subjected to isostatic pressing that includes heating and pressing. Thus, the metal container shrinks and presses on the powder evenly and turns the powder into a nugget. The metal container is moved out of the oven and broken to release the nugget. A substrate is cut from the nugget. With the hot isostatic pressing, the substrate exhibits only a few flaws and is large, fine, homogenous and strong so that the substrate is not vulnerable to deformation in a high-pressure environment.

  • Patent number: 8333915
    Abstract: A fine-structure transfer method in which a fine-featured pattern formed on one of the two surfaces of a stamper is pressed against a coating of a resist on one of the two surfaces of a transfer element so as to transfer the fine-featured pattern to the resist coating, wherein the atmosphere in the space between the stamper and the transfer element is replaced by the vapor of the resist before the stamper is pressed against the transfer element.

  • Patent number: 8211214
    Abstract: The present invention is directed toward a method for reducing pattern distortions in imprinting layers by reducing gas pockets present in a layer of viscous liquid deposited on a substrate. To that end, the method includes varying a transport of the gases disposed proximate to the viscous liquid. Specifically, the atmosphere proximate to the substrate wherein a pattern is to be recorded is saturated with gases that are either highly soluble, highly diffusive, or both with respect to either the viscous liquid, the substrate, the template, or a combination thereof. Additionally, or in lieu of saturating the atmosphere, the pressure of the atmosphere may be reduced.

  • Patent number: 8163212
    Abstract: The present invention provides a process for producing pellet of EVOH comprising the steps of introducing an EVOH solution containing alcohol into an apparatus, contacting the solution with water in the apparatus to let out the alcohol with water and then letting out an EVOH hydrous composition from the above-mentioned apparatus (step 1); cutting the EVOH hydrous composition let out therefrom to obtain EVOH hydrous composition pellets (step 2); introducing the obtained EVOH hydrous composition pellets into a dryer to reduce a water content thereof (step 3); melt-kneading the pellets, whose water content is reduced, in an extruder (step 4); and cutting EVOH discharged from the extruder to obtain the pellet of EVOH (step 5). Thus, the EVOH hydrous composition obtained by removing alcohol without deteriorating the environment can be efficiently dried, and pellets having less thermal degradation in drying and a uniform shape can be obtained.

  • Patent number: 8092737
    Abstract: Disclosed is a method of micro/nano imprinting, which applies soft mold, pre-shaping sealing film, and soft holder arrangements to the micro/nano structure imprinting process of the curved substrates. The method of the present invention can prevent the curved surface from crumbling, which may result from high gas pressuring, and can obtain uniform imprinting pressure distribution throughout the whole curved substrate. Moreover, replicating micro/nano structures onto double-sided curve, both convex and concave, surfaces can also be achieved.
