Patent number: 11619005Abstract: A seamed press felt formed from a base fabric having a CD width and an MD length with two opposing MD ends that are joined to form a continuous belt. MD oriented yarns form uniform loops at the two opposing MD ends that are interdigitated to define a pintle channel extending across the CD width. CD oriented yarns are connected to the MD oriented yarns, in a woven or non-woven construction. Loop open spaces are located within the loops on each of the two opposing MD ends in a seam region, with the loop open spaces being defined between a last one of the CD yarns at each of the two opposing MD ends and the pintle channel. At least one CD monofilament support yarn is located in the loop open spaces on each of the two opposing MD ends. The at least one CD monofilament support yarn has a diameter that is at least 1.6 times a diameter of the CD oriented yarns. A pintle extends through the pintle channel to form a seam.Type: GrantFiled: July 10, 2019Date of Patent: April 4, 2023Assignee: AstenJohnson International, Inc.Inventors: Brent Swaine, Gary Linstad, John Snead, John Xu, Rick Phillips

Publication number: 20140243265Abstract: High-specificity antibodies can distinguish between modified (e.g, hIGF-1/Ea 3mut) and endogenous wild-type human IGF-1 proteins. These antibodies have little or no cross-reactivity with hIGF-1 or hIGF-2. They also have little or no cross-reactivity with rodent IGF-1 or IGF-2. The antibodies can be used in pharmacokinetic (PK)/pharamcodynamic (PD) assessments of IGF-1/E peptides that have been administered to humans or animals.
