  • Patent number: 11859480
    Abstract: A method may include monitoring, for two or more well heads of a hydraulic fracturing system, an operation or a state of one or more subsystems of the hydraulic fracturing system. The hydraulic fracturing system may include one or more fracturing rigs, one or more blending equipment, one or more power sources electrically connected to a first subset of the one or more fracturing rigs, or one or more fuel sources fluidly connected to a second subset of the one or more fracturing rigs, and one or more missile valves. The hydraulic fracturing system may further include one or more zipper valves, one or more well head valves, and multiple well heads. The method may further include controlling, based on an operation schedule for the hydraulic fracturing system and based on monitoring the operation or the state, fluid pressures at the two or more well heads for continuous pumping.

  • Patent number: 7351037
    Abstract: A Y-connect fastener (210) is provided for firmly fastening ceiling fan blades (26) to mounting brackets (20). A plurality of protuberant members (32) extend upwardly from the mounting brackets (20), and have head portions (72) and shank portions (74) which fit through apertures (62) in the ceiling fan blades (26). The fastener (210) has an upper surface (214), a lower surface (216), and peripheral edge portions (220) extending between the upper and lower surfaces (214, 216). Openings (224, 226) are formed in the peripheral edge portions (220) in alignment for sliding the opening (226) over one of the shank portions (74), and then rotating the fastener (210) to twist the two openings (224) around two of the shank portions (74), pressing the fastener (210) between the head portions (72) of the protuberant members (32) and the upper surface of ceiling fan blade (26).
