Abstract: A nitric oxide generator generates nitric oxide from a mixture of nitrogen and oxygen such as air treated by a pulsating electrical discharge. The desired concentration of nitric oxide is obtained by controlling at least one of a frequency of the pulsating electrical discharge and duration of each electrical discharge pulse.

Abstract: Systems and methods are provided for providing continuous configuration deployment. A configuration definition object may be obtained from a remote datastore. The obtained configuration definition object may be stored in a local datastore. The configuration definition object may be obtained and stored in advance of a scheduled maintenance. The configuration definition object may be obtained in response to the configuration definition object being committed to the remote datastore. The configuration definition object may be used to generate different configuration objects. A configuration object may be generated from the configuration definition object and one or more system characteristics. A service request may be received, and the configuration object may be executed to perform a configuration of a computing system.

Abstract: The invention is directed to a center deck assembly for a tire building drum. The tire building drum is rotatably mounted on a central drive shaft and includes a center section. The center deck assembly is disposed in the center section of the drum and includes a hub that seats on and is secured to the central drive shaft. At least one piston extends circumferentially in the tire building drum about the hub and a plurality of segment bars are disposed about the circumference of the center deck assembly. The at least one piston is operably connected to the segment bars by a plurality of linkages, in which each of the linkages includes a scissor-lever mechanism.

Abstract: A stator rim structure for a gas turbine engine comprises a stator having an end wall and a discourager defining a channel therebetween. The end wall is adjacent to a hot gas flow and the discourager is adjacent to a purge flow. A rotor has an angel wing extending into the channel. At least one supply passage is disposed within the stator and extends through the discourager and at least one aperture fluidly couples the supply passage with the channel. A flow of cooling air is fed from the supply passage into the aperture and into the channel to form a fluidic dam discouraging ingestion of the hot gas flow.

Abstract: A second stage tire building drum is disclosed. The tire building drum has two hubs with an inner sleeve mounted to a central shaft of the tire building drum and configured for axial movement. At least one of the hubs is configured for free axial movement. Preferably, each hub further include a sliding sleeve mounted on the inner sleeve for unconstrained sliding in the axial direction relative to the inner sleeve. Preferably, each hub has a bead receiving mechanism mounted on the sliding sleeve and comprised of one or more segments that are radially expandable. Preferably, each segment has a pocket with a curved surface for receiving a bead.

Abstract: A method of building a tire on a second stage tire building drum is disclosed. The method employs the steps of mounting a green cylindrically shaped tire carcass onto a tire building drum so that each bead are seated in a respective bead pocket segment, inflating the carcass under low pressure and expanding the carcass into engagement with tread and belt assembly while allowing the one or more of the hubs or one or more of the bead pocket segments to freely slide in the axial direction.

Abstract: A second stage tire building drum is disclosed. The second stage tire building drum comprises a first and second hub, wherein each hub is mounted on a central shaft of the second stage tire building drum. Each hub is axially movable and has a bead receiving mechanism. The bead receiving mechanism includes one or more bead segments, wherein each bead segment has a pocket.

Abstract: A method of forming a tire having a first and second bead on a tire building drum is disclosed. The method includes the steps of applying a green tire carcass onto the tire building drum, said tire building drum having a left and right hub, each hub having a bead pocket. The method includes the steps of placing the first and second bead onto a first and second respective bead pocket of the tire building drum and then inflating the carcass into engagement with a belt and tread package while moving at least one of the left and right hubs in the axial direction at a controlled velocity towards the other respective hub.

Abstract: A rotor assembly has a vane which engages an eccentric cam block using an insert. The insert is removably attached to the vane. The vane is captured within a transverse slot in the rotor and executes reciprocal motion transversely to the axis of rotation of the rotor as the rotor rotates.

Abstract: A method of casting a rotor using a cavity and core mold allows a longitudinal slot oriented transversely to the axis of rotation to be finish ground to high precision and tight tolerances by casting the slot to have a wider section which extends from the axis to a radius greater than the radii of the hubs of the rotor, and a narrower section which extends from the wider section to the outer surface of the rotor. The geometrical relation of the slot sections to the hubs as cast permits the grinding step to be performed without forming a leak path in either of the hubs.

Abstract: Present embodiments provide an automated system for laying pipe which includes various clearing functions in order to clear impingements and jams of pipe being fed to a conveyor or other structure while dispensing the pipe from the trailer. Some embodiments include uprights which are adjustable to increase the carrying capacity of piping. Other embodiments provide adjustable members which raise and lower to aid in clearing the pipe. Other embodiments provide a gate or arm which may be actuated to push or hold pipes back allowing one pipe to feed at a time. Still further, a transition cradle may be utilized to hold pipes back and actuate a single pipe. These features allow for clearing of various types of jams in the feed process so that a single pipe may be cleanly actuated to a conveyor for feeding from the vehicle.
