The Curtiss-Wright Corporation is an American-based, global diversified product manufacturer and service provider for the commercial, industrial, defense and energy markets. Born in 1929 from the consolidation of Curtiss, Wright, and various supplier companies, by the end of World War II it was the largest aircraft manufacturer in the United States, supplying whole aircraft in large numbers to the U.S. Armed Forces. It has since evolved away from final assembly of finished aircraft, becoming a component manufacturer specializing in actuators, aircraft controls, valves, and surface treatment services. It also is a supplier to commercial nuclear power, nuclear navy systems, industrial vehicles and to the oil and gas industries. Wikipedia.

Curtiss-Wright | Date: 2014-06-24

A check valve apparatus includes at least one first test channel including a first pathway extending through a valve body and in communication with a flow path. The pathway is configured to receive a test stick for inserting through the pathway of the test channel to engage a disc such that the disc moves from the open position to the closed position. In further examples, methods for testing a check valve include the step of moving an end of a test stick to engage a downstream face of a disc such that the disc is moved against a bias of a biasing device from the open position to the closed position. The method further includes the step of inspecting an interior portion of the check valve apparatus.

Arrangements for promoting the restriction of fluid flow along a shaft via providing a deformable ring member in an annulus between the shaft and housing. In an initial general condition, the deformable ring member permits free fluid flow in a general direction along the shaft while in a second, constricted condition, the deformable ring closes or blocks a gap or clearance normally conducive to free fluid flow to thereby restrict fluid flow. An actuation medium, which can take any of a very wide variety of forms, preferably promotes constriction of the deformable ring member directly or indirectly.

A heat shield for a thrust bearing assembly of a pump. The heat shield includes a member having an inner surface and an outer surface. A raised flange is formed on a perimeter of the inner surface. The raised flange is configured to seal with a back surface of a thrust shoe holder, and form a cavity between the inner surface and the back surface of the thrust shoe holder. At least one weep hole is on the flange. The weep hole is configured to allow water to enter the cavity to form an insulating stagnant water layer.


Neutron absorber members for a control rod guide tube of a spent fuel assembly are provided as a tube split throughout a length thereof. In further examples, an insertion apparatus for inserting a neutron absorber member into a control rod guide tube of a spent fuel assembly includes an insertion tool base and an insertion tool rod. The insertion tool rod is removably secured within and extending from the insertion tool base according to a position of the control rod guide tube into which the neutron absorber is to be inserted. In further examples, a neutron absorber member retainer for a top nozzle of a spent fuel assembly is provided. The retainer includes a plate configured to inhibit a neutron absorber member inserted in a control rod guide tube from removal.

A lifting tool 100 form part of a lifting apparatus associated with an aircraft handler 10 for applying a lifting load to an undercarriage of an aircraft. The lifting apparatus comprise a pair of opposed lifting tools 100 which engage end portions of an undercarriage wheel axle 300 for lifting. Each lifting tool 100 has a body 101 with a cavity 103 therein filled with a plurality of axially displaceable closely packed pins 105 which permit insertion of a portion of the axle or adaptor means into the cavity, and other pins, in use, surrounding said portion provide support and transfer the lift load to the surrounding body 101.


Patent

An electrical connector assembly for suppressing a back electromotive force (EMF) spike originating from an electromagnetic device is provided. The electrical connector assembly includes a pin-side electrical connector coupled to the electromagnetic device. In one example, the pin-side electrical connector has a diode opening surrounded by an insulating material. The electrical connector assembly further includes a socket-side electrical connector for mechanically mating with and electrically coupling to the pin-side electrical connector. The socket-side electrical connector includes a suppression diode for suppressing the back EMF spike from the electromagnetic device. The suppression diode is positioned within the diode opening when the socket-side electrical connector is mechanically mated with and electrically coupled to the pin-side electrical connector.

A modular multilevel converter system. The system includes a plurality of series connected two-terminal M2LC cells arranged into at least two output phase modules. A first one of the output phase modules has an inductance and an effective capacitance associated therewith. The first one of the output phase modules is configured so that a natural resonant frequency of the inductance with the effective capacitance of the first one of the output phase modules is greater than at least one of the following: an operating frequency of the first one of the output phase modules; a switching frequency of the first one of the output phase modules; and a switching frequency of any of the M2LC cells of the first one of the output phase modules.
