  • Patent number: 10427345
    Abstract: Process for continuous fabrication of highly aligned polymer films. A polymer-solvent solution is subjected to a high shear, high temperature, Couette flow to extrude a thin film having polymer chain disentanglement. The extruded thin film is frozen and the solvent is allowed to evaporate to form a dried film. The dried film is mechanically drawn using a constant force, adaptive-thickness drawing system to align polymer molecular chains through plastic deformation. A suitable polymer is ultra-high molecular weight polyethylene.

  • Patent number: 10335973
    Abstract: A method of processing a polymeric web includes providing a forming screen configured for supporting and moving with the web in a machine direction. The forming screen has a plurality of elliptical screen openings, each having a major axis perpendicular to the machine direction and a minor axis parallel to the machine direction. The method includes continuously depositing the web onto the forming screen and passing the web and forming screen through a water stream having a pressure level sufficient to cause the web to be forced into the screen openings, thereby forming protrusions extending from the planar surface of the web. Each protrusion has an apex, an opening at the apex, and an elliptical cross-section parallel to the planar surface of the web. The elliptical cross-section has a protrusion axis ratio that may be selected so as to produce a desired protrusion axis ratio.

    Abstract: To produce a hole in a part (1) made of a thermoplastic composite, the part is locally heated to a plastic forming temperature Tf and the fibres (10) of the composite are progressively moved apart at the same time as the matrix (11) in the plastic state is pushed back radially relative to the axis of the hole, firstly to form a starter hole and then to enlarge the starter hole up to the desired hole dimensions. When the hole has been produced, an operation for sizing the thickness of the part in the hole region is carried out without removal of material because of the excess material pushed back from the hole. A tool having a needle (31), the cross section of which progressively changes between a tapered end (311) suitable for producing the starter hole and a heel (312), is used to produce the hole by the method.

  • Patent number: 7758330
    Abstract: For forming a ready-to-bake, endless dough ring, a dough piece is first round kneaded in a round-kneading station and then fermented in a fermenting station. In a pressure station, flattening pressure is exerted on two sides of the dough piece for a flat round piece to produce. After a relaxation interval, an inside hole is punched into the relaxed dough piece in a punching station, with a dough ring being obtained. The individual stations of a corresponding dough treatment system are connected to each other by means of a conveyor. Then secondary fermenting of the shaped dough ring takes place, which is followed by baking of a ring article. The result is an efficient method of forming a ready-to-bake, endless dough ring. Producing the baked ring article can be completely automated.

  • Patent number: 7731878
    Abstract: A process of forming a microperforated plastic film includes providing a post tool having multiple posts, bringing plastic into contact with the post tool such that the plastic conforms to the shape of the posts, and solidifying the plastic into a solidified plastic film having a plurality of microperforations in the shape of the posts. Another step in the process is displacing any skins formed over the holes after solidifying the plastic. The process may be used to form a film for sound absorption where the posts are shaped and arranged to provide microperforations that provide a particular sound absorption spectrum. In one embodiment, the microperforations each have a narrowest diameter of 20 mils, a narrowest diameter less than a film thickness, and a widest diameter greater than narrowest diameter. The widest diameter may be about 125% or more of the narrowest diameter in an embodiment.

    Abstract: An apparatus for docking dough includes a base member, a plurality of protrusions extending from a lower surface of the base member, and a handle secured to an upper surface of the base member. The base member is not flat, but rather has a curvature that enables the apparatus to be rocked from side to side when placed on a surface. Thus, in use, the apparatus is first placed on and manually pressed into a dough, such as an uncooked pizza dough. Then, the apparatus is rocked from side to side by the user to dock the dough, ensuring that dimples or divots are made throughout the dough.
