  • Publication number: 20210336543
    Abstract: An apparatus comprises an emulator and a corresponding compensator. During operation, the emulator produces, at different instants of time, an emulated output current value representative of an amount of current supplied from an output voltage to a load. In general, the compensator provides selective compensation to the emulated output current value over time. For example, for a first time duration, compensation adjustments from the compensator are used to modify the emulated output current value. For a second duration of time, compensation adjustments from the compensator are not used to modify the emulated output current value. Disabling or discontinuing application of adjustments (such as based on the actual measured output current) during the second time duration (such as during a respective transient condition) provides more accurate and timely generation of a respective emulated output current value.

  • Patent number: 9003632
    Abstract: A thimble mechanism for retention of a shackle in a wire rope loop termination. In one preferred embodiment, a thimble device is provided for a shackle having a pair of opposed legs with each leg having an end with a width smaller than a depth. The thimble device includes a thimble body having an external arcuate edge with a rope groove for receipt of a wire rope therein. A central opening extends through the thimble body with the central opening larger than the width but smaller than the depth of the shackle ends. A keyway is provided in the thimble body extending from the central opening to the arcuate edge of the thimble body.

  • Patent number: 5381650
    Abstract: A swivel hardware assembly which includes a bail having a base with an opening therethrough. A shank, terminating in a head, passes through the opening to form a pivotal connection between the bail and the shank. The first thrust washer is juxtaposed between the head and the base. A second thrust washer is juxtaposed between the head and the base. Each thrust washer has at least one surface covered with a self lubricating material, the self lubricating surfaces mating with each other to form a bearing surface.

  • Patent number: 4102295
    Abstract: A load indicator is connected between a load line and a load handling member such as a hook. The indicator includes a hollow cylindrical housing, a plunger assembly including a transverse head slidably mounted in the housing, a pilot rod integral with the head and extending to a location outside the housing, means connecting a first end of the housing opposite the plunger rod and means connecting the plunger rod to the load line and to the load handling member, and a compression spring in the housing urging the plunger head toward the first end of the housing. The wall of the housing has several sight openings therethrough. A sight band of contrasting color is fixed to move with the plunger assembly inside the housing and to be visible through the sight openings.
