Abstract: A tailgate and hinge assembly for a pickup truck includes a pair of L-shaped hinge brackets secured to opposite sides of the truck body of the pickup truck. Each hinge bracket has an inverted U-shaped cam track therein for receiving the hinge cam pins on the tailgate. This hinge assembly allows the tailgate to be readily moved between a vertical closed position, a horizontal position and a depending vertical position. The novel hinge assembly enables the tailgate to be maintained in the open horizontal position without the need of chains or linkages.

Abstract: The present invention describes use of a fluid having a VI of at least 130 to improve the energy efficiency of a hydraulic system. Furthermore, the present invention relates to a hydraulic system comprising a hydraulic fluid having a VI of at least 130, a unit for creating mechanical power, a unit that converts mechanical power into hydraulic energy, and a unit that converts hydraulic energy into mechanical work. Preferentially, engine speed can be reduced to decrease load and stress while delivering the same amount of hydraulic power.

Abstract: A device applied to regulating the flow rate of air flowing in a rotary shaft of a turbomachine, the shaft including at least one through orifice for passing air. The device at least one shutter member for shutting the orifice and secured to a deformable blade presenting bi-linear behavior, the blade being secured to the shaft and being suitable for deforming under the effect of the centrifugal force that results from the shaft rotating such that the shutter member is suitable for taking up two different positions depending on the speed of rotation of the shaft: one position in which it shuts the orifice; and another position in which it releases the orifice to allow air to pass through.

Abstract: A device for measuring torsional distortion of a body comprises first and second clip portions each having a central part and two legs depending from the central part, each leg having adjacent the free end thereof a groove or projection for engaging a respective projection or groove (14) provided in the body (16) to mount the clip portion the body rotationally fastened therewith. A bridge interconnects the clip portion. The bridge is less stiff than the clip portions whereby relative rotational displacement of the clip portions caused by torsional distortion of the body will cause proportional deflection of the bridge. Means, for example a SAW device (15), are provided for measuring the deflection of the bridge to provide an indication of the torsional distortion which produces the deflection of the bridge. Also (20) for the interior all of a hollow body.

Abstract: A wheel nut assembly includes a stud (1), a main wheel nut (4) mountable on threads (3) provided on the stud, and a retaining nut (6) engageable with threads (5) provided on the stud to prevent accidental loosening of the wheel nut (4). The threads of the wheel nut (4) and the threads for the retaining nut (6) are of opposite hand. A cap (11) is slidably mounted on the retaining nut (6) and biased into a first position by a spring (16). The cap (11) includes multi-hexagonal profiles (12, 14) for engaging hexagonal profiles (13, 15) provided on the retaining nut (6) and on the main wheel nut (4). Accordingly, in the first position, the retaining nut (6) and the main wheel nut (4) are rotationally locked to each other and because of the opposite hand of the respective threads it is not possible to remove the retaining nut. To release the retaining nut (6), the cap (11) is grasped and pulled to the limit permitted by the spring (16) to permit rotation of the retaining nut (6) and removal thereof.
