  • Patent number: 10066738
    Abstract: A method of controlling a transmission having a gearbox and a pump operable to circulate a fluid through the gearbox, includes sensing an acceleration of the vehicle, and adjusting an operating state of the pump. The operating state of the pump is adjusted to change the operating state of the pump from an initial operating state, to an adjusted operating state, when the acceleration of the vehicle is greater than an acceleration threshold. When the acceleration of the vehicle decreases from being greater than the acceleration threshold to being below the acceleration threshold, the operating state of the pump is returned to the initial operating state. The operating state of the pump may include a speed of the pump, a control signal representing a fluid flow rate for the current speed of the pump, or a fluid flow circuit for supplying the fluid to the pump.

  • Patent number: 5783312
    Abstract: A continuous strip of sheet metal is progressively lanced and then expanded by coining rolls to form an expanded ladder-like reinforcing strip. The strip has laterally extending parallel spaced bars integrally connected on one side by a coined solid spline and on the other side by a coined spline lanced to form slits at longitudinally spaced intervals. The strip is roll-formed into a U-shaped channel which is fed into an extruder head for reinforcing an extruded resilient weatherstrip having a tubular portion projecting from the embedded continuous solid spline and a retaining wall portion reinforced with the embedded lanced spline.
