Patent number: 10385491Abstract: An apparatus for making a spunbond nonwoven from monofilaments of thermoplastic synthetics has a spinneret for spinning and emitting the filaments in a travel direction, a cooler downstream of the spinneret for cooling the spun filaments, and a stretcher downstream of the cooler for stretching the filaments. An intermediate passage extending in the travel direction between the cooler and the stretcher has upstream and downstream converging passage sections. The upstream passage section in the travel direction of the filaments having a shorter length than the downstream passage section in the travel direction of the filaments. A ratio BE/BA of an inlet width BE to an outlet width BA of the upstream passage section is 1.5 to 5.5. A ratio of an inlet width bE, to an outlet width bA, of the downstream passage section is 1 to 4.Type: GrantFiled: January 25, 2017Date of Patent: August 20, 2019Assignee: REIFENHAEUSER GMBH & CO.

Patent number: 10370490Abstract: Disclosed herein are polycarbonate fibers and fibrous substrates, such as papers, containing such fibers. The polycarbonate fibers are produced from a polymeric composition comprising a cross-linkable polycarbonate containing endgroups derived from a monofunctional benzophenone or containing repeating units derived from a difunctional benzophenone. The polycarbonate fibers can be combined with other fibers to form the fibrous substrate. Upon exposure to ultraviolet light, crosslinking of the polycarbonate fibers will occur, improving various properties of the fibrous substrate.Type: GrantFiled: April 3, 2015Date of Patent: August 6, 2019Assignee: SABIC GLOBAL TECHNOLOGIES B.V.Inventors: Amanda Marie Flores, Jacob LaBelle, Peter James Zuber, Kim R.

Patent number: 10046818Abstract: An endless rubber track belt includes an endless, elongate carcass having an outer surface, an inner surface, and at least one reinforcing layer. The inner surface defines a plurality of wheel path areas. A plurality of tread lugs are disposed on the outer surface. A plurality of guide lugs are disposed on the inner surface, where each guide lug includes oppositely disposed drive faces, an upper face between said drive faces, and oppositely disposed end faces. At least one reinforcement strip is disposed inward from the inner surface and outward from the at least one reinforcement layer. The at least one reinforcement strip is positioned adjacent the plurality of wheel path areas. The at least one reinforcement strip may include a bias ply formed of two layers of cords arranged in opposite +/? bias angles. The +/? bias angles may range from about +/?20° to about +/?80°.Type: GrantFiled: November 28, 2017Date of Patent: August 14, 2018Assignee: ContiTech Transportbandsysteme GmbHInventors: Ronald Wellman, Mohamad Bachir

Patent number: 9993945Abstract: According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.Type: GrantFiled: July 8, 2015Date of Patent: June 12, 2018Assignee: Johns ManvilleInventors: Mingfu Zhang, Klaus Friedrich Gleich, Asheber Yohannes, Michael John Block, Jawed Asrar, Derek Cooper Bristol, Christopher P Sandoval

Patent number: 9868639Abstract: There has been a problem that wrinkles easily occur on a carbonaceous film produced by the use of a continuous production method and on a graphite film obtained by heat-treating the carbonaceous film. In the present invention, heating treatment is carried out on a polymeric film while applying pressure to the polymeric film in the film thickness direction with the use of a continuous carbonization apparatus. This makes it possible to obtain a carbonaceous film and a graphite film in which wrinkling is reduced.Type: GrantFiled: September 19, 2013Date of Patent: January 16, 2018Assignee: KANEKA CORPORATIONInventors: Satoshi Katayama, Yusuke Ohta, Takashi Inada, Makoto Kutsumizu, Yasushi Nishikawa

Patent number: 9683317Abstract: A penetration-resistant article includes at least one woven structure that has thermoplastic fibers and high-strength fibers, wherein the high-strength fibers have a strength of at least 100 MPa according to ASTM D-885, and a second weave of the woven structure has high-strength fibers. The thermoplastic fibers lie on the second weave and are connected to the second weave by way of at least one warp and/or weft thread. The thermoplastic fibers account for a proportion by weight with respect to the weight of the double weave of 5 to 35%. A method for producing such a woven structure is also described.Type: GrantFiled: February 19, 2014Date of Patent: June 20, 2017Assignee: TEIJIN ARAMID GMBHInventors: Christian Böttger, Rüdiger Hartert
