  • Patent number: 8251854
    Abstract: A transmission apparatus for transmitting power from a motor for driving an airport ground support tractor includes a torque converter for transmitting torque from the motor. A planetary gear train is structured such that in a first mode of operation, when an input shaft is rotated in a first rotational direction, a casing is rotated in the first rotational direction. However, in a second mode of operation, rotation of the casing relative to a housing is inhibited so that a support rotates in a second rotational direction. The arrangement is such that a driven end of a main shaft is secured to the support so that the support selectively drives the main shaft in the first rotational direction and the second rotational direction. An electro-hydraulic actuator selectively moves a synchro device between a first and second dispositions thereof for establishing a first and second gear ratios.

  • Patent number: 8132817
    Abstract: An air suspension control apparatus for a vehicle is disclosed. The apparatus includes a charge tank maintained at a first air pressure such that selective filling of the charge tank with compressed air is permitted. The arrangement is such that, in a first disposition of the tank air valve, the charge tank is maintained at a second air pressure which is less than the first air pressure. When the tank air valve is in a second disposition thereof, the charge tank is maintained at the first air pressure. In a third mode of operation of the air suspension control apparatus, the tank air valve is in the first disposition thereof and a ride height air valve is in the first setting thereof. The arrangement is such that the first pressure within the charge tank rapidly inflates the air spring from the third pressure to the second pressure so that driving of the vehicle is permitted.

    Abstract: A dryer bar apparatus of a dryer for drying a web in a papermaking machine includes a number of turbulence bars circumferentially spaced equidistantly around the inner surface of the dryer shell for generating turbulence within a layer of condensate. The arrangement is such that uniformity of the transfer of thermal energy in the cross machine direction is maximized while the transfer of thermal energy through the dryer shell from the inner to the outer surface is minimized. Also, the number of turbulence bars is determined by the equation: N=int{2?Ri/[4?(Ri/d)½+W]} in which: N=the number of turbulence bars in the dryer shell; int=an integer number of a value in { } brackets; ?=3.1415; Ri=the inside radius of the inner surface of the dryer shell in inches; d=an average depth of the layer in inches; W=a width of each of the turbulence bars in inches.
