  • Patent number: 7650927
    Abstract: A method of controlling a vehicle heating, ventilation, and air conditioning (HVAC) system. Outside or ambient temperature, evaporator temperature, and coolant temperature are measured with sensors. These values, along with a TAO, which is a calculated value of outlet temperature in the vehicle, are sent to a controller. The controller determines a predicted heater core outlet temperature based upon the coolant temperature. Based upon the outside air temperature and coolant temperature, the controller will decide whether to use the previously determined estimated heater core outlet temperature or to substitute an alternate value for the heater core outlet temperature to determine a position for the air mix door. After calculating the air mix door position, the controller signals an air mix door movement device to adjust the air mix door to the required position. Position of the air mix door affects the air temperature inside of the vehicle.

  • Patent number: 7523632
    Abstract: A modular rolling mill comprises a plurality of rolling units having work rolls configured and arranged to progressively reduce the cross sectional area of a product received along a mill pass line. Gear units are mechanically coupled to each rolling unit, with each gear unit in turn being mechanically coupled to a driven line shaft by first bevel gear sets. The ratios of the first bevel gear sets progressively increase from the first to the last of the gear units to thereby accommodate a progressively increasing speed of the product being rolled. A second bevel gear set is associated with the last gear unit. The ratio of the second bevel gear set is the same as the ratio of the first level gear set of the penultimate gear unit. The line shaft is selectively coupled to the last gear unit via one or the other of its first and second bevel gear sets.

  • Patent number: 7244322
    Abstract: The present invention relates to a method for forming a fire combustion modified batt. The method comprises the step of forming a blend of nonwoven and oxidized polyacrylonitrile fibers into a web. The oxidized polyacrylonitrile fibers are fire resistant and when blended with nonwoven fibers are relatively easily processed into a batt. A second blend of nonwoven fibers can be formed into a web and layered with the oxidized polyacrylonitrile fiber web to form the batt. The fibers are bonded together with heat, resin or other bonding material and are compressed and cooled. The fire combustion modified batt is useful as fire barriers and fillers in bedding, upholstery and vehicle and aircraft seats, as insulators for apparel, appliances, walls and ducting, as barriers to separate control systems from a heat source, and as components in fire safety gear such as race driver suits and oven and welding mitts.
