  • Patent number: 4463956
    Abstract: A shield for disposition between a lubricated bearing and a labyrinth seal in a gas turbine engine having a rotating member rotatable about a vertical axis, the shield preventing lubricant contamination of the seal. The shield includes an inner helical baffle on the rotating member between the bearing and the seal and an outer helical baffle on a stationary support between the inner baffle and the seal. The inner and outer baffles radially overlap to foreclose lubricant drip onto the seal and have corresponding helical leads so that the inner baffle can be threaded through the outer baffle when the rotating member is installed on the support.

  • Patent number: 4402515
    Abstract: A labyrinth seal of abradable design between a shaft and a partition separating regions of high and relatively lower gas pressure. The seal is located in close proximity to a gas permeable bearing also disposed between the shaft and the partition and located in the relatively lower pressure region. The seal permits limited leakage gas flow toward and through the bearing and pieces of seal material abraded during shaft rotation tend to entrain in the leakage gas flow. A baffle is disposed on the shaft between the seal and the bearing and defines a portion of a serpentine path for the leakage gas flow. A contamination trap containing a self-supporting adhesive material is formed on the baffle perpendicular to a portion of the serpentine path so that while the leakage gas turns 90.degree. at the trap, the heavier particles of abraded material impact on and are captured by the adhesive material.

  • Patent number: 4268220
    Abstract: A gas turbine engine having variable geometry flow controllers therein for controlling mass flow in accordance with engine operation includes a rotor with a wide variation in thrust forces thereon during different phases of engine operation countered by a variable axial load integrating device having a rotating hydraulic thrust compensating piston mounted forwardly of the rotor in association with a rotor thrust bearing and further including means for generating a centrifugal head in accordance with engine speed and wherein improved oil distribution panels are included to evenly distribute oil between the rotating piston and a nonrotating counterpiston to form a uniform depth of rotating oil automatically regulated by an integral, flow regulator having flow area therethrough varied in accordance with axial position of a thrust bearing carriage that has the variable rotor thrust loading imposed thereon.

  • Patent number: 4123968
    Abstract: A power vent is disclosed including a housing assembly having a base and a cylindrical, open ended shroud joined to the base and within which is supported a fan assembly. A wire frame is molded into the inner peripheral surface of the shroud to reinforce the shroud and also provide a bracket for supporting the motor of the fan assembly. A molded plastic hood including hood support brackets is securable to the shroud so that the assembly may be employed as a roof vent. In another embodiment, the base of the housing may be shaped to receive a louver assembly and the assembly may be used as a gable end vent.

  • Patent number: 4073106
    Abstract: Connectors and end caps are provided to connect adjacent roof ridge ventilator sections and to close the ends of the assembly. The connectors include a cutout, intermediate wall, an outer jacket and inner sleeve defining slots to receive the ends of adjacent ventilator sections. The end caps include a deflectable wall having a central depression and bulge. An outer end cap jacket and inner end cap sleeve define a channel to receive the end of the ventilator assembly.

  • Patent number: 4050277
    Abstract: A multistation roll form machine for forming an article of complex shape such as a roof ridge vent having integral dams along the inner lateral edges of the ventilation panels includes a longitudinally extending support frame, a first group of individual roll forming stations, a lancing subassembly and a second group of individual roll forming stations. Each of the individual stations includes upper and lower roller die sets for continuously and progressively bending the stock material as it is fed through the machine. The first group of roll forming stations progressively bends the stock on itself to form dam portions integral with the lateral edges of the ventilation panels. The lancing subassembly positioned immediately downstream of the first group of individual stations, includes two pairs of outer and inner lancing rolls having teeth formed around their circumferences which lance the stock to form the ventilation openings.

  • Patent number: 4000688
    Abstract: An improved roof ridge ventilator is provided having a peaked hood, descending sidewalls, horizontally extending panels and a dam arrangement defined by a vertically extending, reversed bent inner sidewall. Flashing sections are integral with the inner sidewalls. A plurality of rows of vent passages are formed in the panels. Each row of these passages is hooded by oppositely disposed, alternating offset straps. Vent passages are provided along the outer edge of the panels and are partially covered by downwardly and inwardly inclined baffles.
