Abstract: Apparatus and methods for adjusting the pitch of a fluid reactive blade member carried upon a rotor in response to a speed difference between the rotor and a reference speed shaft.
Abstract: Steam generating apparatus and methods wherein a liquid is recirculated within a boiler by use of a constant speed dynamic feed water pump acting both to feed the boiler and to effect recirculating therein by a jet pump with its jet nozzle in liquid flow series with the dynamic pump. The jet pump also receives water from a steam drum for recirculation through the boiler. In the event of excess feed water supply to the boiler a step-function level control for the steam drum bypasses liquid to a condenser. A second jet pump acts to utilize excess feed water to supply cool water from the condenser well under pressure to the dynamic pump so that no water is bypassed to the condenser under on-design operating conditions. For waste heat recovery to provide shaft power automatically with simplified controls.
Abstract: The fuel nozzles in a variable geometry combustor cooperate with an inwardly projecting liner wall section to define a sheltered pilot combustion zone within the liner. Simultaneously operable inlet valves are provided for admitting a selectively variable quantity of combustion air into the pilot zone.

Abstract: A toroidal pressure vessel comprises two annular, complementarily formed axial sections which are intersecured along a duality of annular joint lines that circumscribe and are mutually offset along the axis of the toroid. The axial sections are formed by machining a pair of end portions removed from a length of thick-walled metal tubing.
Abstract: An automotive vehicle includes an aerodynamic fin effective for vehicle control at relatively high vehicle velocity, and a nozzle directing a reaction jet toward said fin render the latter also effective for vehicle control at relatively low vehicle velocity.
Abstract: A pump is used to exhaust oxygen rich waste gas to ambient pressure in an inert gas generating system in order to improve the performance of the permeable membrane air separator component and to insure sufficient generation of inert gas when available source air pressure is low.
Abstract: A method and apparatus for casting of fragile complex shapes by the formation of a two layer wax mold about a pattern of the shape to be cast. Thereafter, the pattern is removed from the mold and the outer layer of wax dissolved. The slip is then poured into the mold and allowed to solidify before the inner layer of the mold is completely removed from the cast article.
Abstract: An emergency power unit method and apparatus with means for inhibiting vibration of the catalyst bed while permitting spring loading thereof, and for automatically compensating for movement of the catalyst bed caused by the spring loading.
Abstract: A bearing support structure for a journal bearing including a plurality of overlapping compliant foils mounted upon one of a pair relatively rotatable members to form an outwardly diverging surface to support the other of the members. The outwardly diverging surface may be formed by varying thickness shims included along the axial length of the plurality of foils.
Abstract: This invention controls the air pressure in an aircraft cabin in response to a selected landing field altitude and to a selected maximum permissible cabin pressure rate.

Abstract: A fluid compressor control and operation method wherein a tangential velocity is imparted to all or only a selected part of fluid flowing to a rotating impeller of the compressor. In a preferred embodiment, the impeller is of centrifugal radial flow configuration with an inlet duct effecting inlet flow radially inwardly, and then axially to the impeller. The compressor includes a plurality of axially elongate guide vanes disposed annularly of the inlet and axially moveable relatively thereof into and out of the inlet fluid flow.
