  • Patent number: 10968914
    Abstract: A method for providing artificial lift with an electric submersible pump system includes providing an electric submersible pump system having a motor, a pump assembly, a seal assembly, and a shaft assembly extending along a central axis from the motor to the pump assembly. The pump assembly includes two or more pump sections and a coupling with a transmission mechanism is located between the two or more pump sections. The motor rotates a motor shaft segment of the shaft assembly that is in engagement with a first pump section and starts the first pump section. One of the transmission mechanisms is moved from a disengaged position to an engaged position where the coupling conveys the rotation of the motor shaft segment to the adjacent shaft segment and starts another of the two or more pump sections.

    Abstract: A ratchet wrench (1) has a flexible clutch ring (500) that forms the mid part of a laminate-like structure comprising a wrench head (200), the clutch ring (500) and a drive element (40). When under load, the compression forces applied to the clutch ring (500) are substantially dissipated around its circumference (508) and inner surface (509), this inward force clamping upon the inherently strong drive outer surface (45). The laminate-like construction enables a reduction in the width or depth of the wrench head without a loss in strength.

  • Patent number: 10487888
    Abstract: Since one end of a spring is received by a planar portion of a spring seat provided on any one of an outer plate and an inner plate, it is possible to support the spring with a planar member without machining a bottom wall face of the outer plate into a planar shape. Since the spring seat has seat guide portions that contact the outer plate, it is possible to suppress the fluctuation of the spring seat and the fluctuation of the spring by the seat guide portions, so it is possible to reliably prevent interference of the spring with its peripheral portion. Therefore, a load on the spring is reduced, so it is possible to improve the durability of a one-way clutch.
