  • Publication number: 20260062896
    Abstract: A leak control device includes first and second flow control assembly, each including a flow sensor; a valve assembly with a valve and an actuator; a cable assembly, including a leak detector cable and a leak sensor, such that the leak control device close the valve to stop a flow water through the leak control device, if the leak control device receives a leak indication from the leak sensor or detects a flow anomaly condition in communication with the flow sensor. Also disclosed is a method of installing the leak control device, measuring an actual flow duration of water flow events, measuring an actual flow quantity, measuring an actual daily water usage, and counting an actual number of daily water flow events.

  • Patent number: 11619005
    Abstract: 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.

  • Publication number: 20220333108
    Abstract: Compositions and methods are provided for silencing the Sulf2 and/or GPC3 genes in vivo. Potent siRNA sequences are provided that silence regions of the Sulf2 and GPC3 genes that are identical in human, mice and non-human primates. Combinations of siRNAs also are provided that result in additivity or synergy with silencing of Sulf2 and/or GPC3. Silencing SULF2+TGF?1 showed a dramatic effect against cancer growth in vitro and in vivo.

  • Publication number: 20140243265
    Abstract: 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. A sandwich ELISA assay, using the antibody of the invention as a capture antibody, can quantify the mutant IGF-1/E proteins in samples.
