A barrier device is provided for an inlet cowl for an aircraft engine including an inner barrel circumferentially surrounding an opening in the inlet cowl formed along an axis of rotation of the aircraft engine, through which air passes to the aircraft engine, the inner barrel including a face sheet disposed on a radially inward side of the inner barrel relative to the axis. The barrier device includes a containment doubler of the inner barrel, disposed on a radially outward side of the inner barrel, and a blade fragment barrier including one or more strips disposed between the containment doubler and the face sheet, so as to extend circumferentially at least partially around the opening and to occupy a radial distance between the containment doubler and the face sheet.

A method for manufacturing an engine poppet valve having a valve head portion and a stem portion made integral by way of a neck portion that increases in diameter toward a tip end, comprising: a valve head portion manufacturing operation in which hot forging is employed to form a stem/head intermediate product comprising an intermediate stem portion and a valve head portion which is made integral with the intermediate stem portion by way of a neck portion; a stepped stem portion manufacturing operation in which cold drawing in which a part of the intermediate stem portion is inserted in press-fit fashion from a base end portion into a stem member inlet surface and a stem member compressing surface of a hollow circular hole die that has a drawing hole and at which the stem member inlet surface that gradually narrows toward a central axis, and the stem member compressing surface that is continuous with the stem member inlet surface and that has a constant inside diameter which is less than an outside diameter of the intermediate stem portion are provided at least at a portion thereof is employed to cause a stepped stem portion comprising a first stem portion which has been made to be of decreased diameter, a step portion which has been formed by the stem member inlet surface, and a second stem portion in which there is absence of decrease in diameter and which is continuous by way of the step portion with the first stem portion to be formed from the intermediate stem portion; and a joining operation in which a stem end portion having a same outside diameter as the first stem portion is joined to a base end portion of the first stem portion.

A method of making a fluid injector for a gas turbine engine includes depositing material onto a piece of tube stock. The method includes machining the deposited material into a fluid injector component. Depositing can include laser cladding the material onto the piece of tube stock. The method can include placing or flowing braze into a braze joint location between the deposited material and another fluid injector component and forming the braze into a braze joint in the braze joint location.

A process for manufacturing a preformed sheet having geometric surface features for a geometrically segmented abradable ceramic thermal barrier coating on a turbine engine component, the process comprising the steps of providing a preformed sheet material. The process includes forming a partially of geometric surface features in the sheet material. The process includes joining the sheet material to a substrate of the turbine engine component. The process includes disposing a thermally insulating topcoat over the geometric surface features and forming segmented portions that are separated by faults extending through the thermally insulating topcoat from the geometric surface features.

To provide an air passage for torch combustion in the torch main body to ensure the freedom of design. A decorative elongated object according to the present invention includes an elongated material (100) with a cross section having a plurality of radial lines (L2) and being uniform from one end (1a) to another end (1b), a cavity being formed at the center of the elongated material, in which the elongated material has a side surface at least partially tapered to be thinner toward the other end (1b) from the one end (1a), with the radial lines (L2) partially cut and removed along a side surface cutting plane intersecting with the side surface.

A microfluidic valve formed in a body having a first and a second surface; an inlet channel extending in the body from the second surface; a first transverse channel extending in the body in a transverse direction with respect to the inlet channel; and an outlet channel extending in the body from the first surface. The inlet channel, the first transverse channel and the outlet channel form a fluidic path. The microfluidic valve further has an occluding portion, formed by the body and extending over the transverse channel; and a piezoelectric actuator coupled to the occluding portion and configured to move the occluding portion from an opening position of the valve, where the occluding portion does not interfere with the fluidic path, and a closing position of the valve, where the occluding portion interferes with and interrupts the fluidic path.

A tool for torquing a regulator onto a cylinder of a portable cylinder assembly. The tool includes a nut and a socket. The nut is configured to fit around a body of a regulator of a portable cylinder assembly. As such, the nut has a first set of grooves that avoids one or more valve assemblies on the body of the regulator. The socket has a cavity extending therethrough such that the cavity consists of three sections: a top section, a middle section and a bottom section. The top section of the socket is configured to be coupled to a device that applies a torque force on the socket. The middle section of the socket is configured to avoid a case of the regulator which is disposed above the body of the regulator. The bottom section of the socket is configured to be coupled to the nut.
