  • Patent number: 9149919
    Abstract: A fastening system and method to removably attach change part components to a capping or filling machine in order to adapt a general purpose machine for use with a specific size or shape container. The fastening system and method uses magnetic forces to pull component parts into alignment and to interlock portions of interchangeable components. In addition, a blocking component is interposed between two other interchangeable component parts or within mushroom slots, securing the components in place, aided by biasing magnets. This system and method relies on a combination of mechanical and magnetic forces by using mechanical forces to reinforce or supplement biasing magnetic forces, and vice versa, creating a durable connection that will withstand the rigors of the filling and capping process, yet which is simple to assemble and disassemble without tools. The less intricate component parts are less prone to damage during assembly, use, or disassembly.

    Abstract: A dual flow check valve includes a valve body having an inner valve cavity, a first valve opening, and a second valve opening. The dual flow check valve further includes a seal disposed within the valve body. The seal is operatively coupled within the valve body such that the seal is configured to move relative to the valve body between an open position, in which the seal allows the gas to flow between the first and second valve openings through the inner valve cavity, and a closed position, in which the seal inhibits the gas and the liquid from flowing through the inner valve cavity from the first valve opening to the second valve opening.

  • Publication number: 20150013158
    Abstract: A method is provided for solid-propellant engines to be dismantled safely and in accordance with environmental standards having been scrapped. For each engine to be dismantled, it is mounted on a static test rig, immersed in a tank filled with water and started such that propellant is used up under the water. The soluble part of the combustion products (gases or condensates) thus remains trapped in the water in the tank while the non-soluble solid products drop to the bottom of the tank. The body of the engine emptied of its fuel in this way and rendered pyrotechnically inert is then taken apart or disassembled. Periodically, the water in the tank is withdrawn and the tank stripped of its deposits such that subsequent dismantling operations can be carried out under proper conditions. All of the combustion products recovered are sent to appropriate reprocessing plants. The method allows high dismantling rates.

  • Publication number: 20150000127
    Abstract: A method for mounting and setting an actuator of an exhaust gas turbocharger and a suitable electric actuating device are provided. The actuating device has an axially movable actuating rod which is connected to a coupling element which for its part is connected via a pivot pin to an actuation section of a bypass valve, the actuation section being configured as a lever arm. In order to set the desired closed position of the bypass valve during a predefined actuation of the actuating device, the coupling element is first connected to the actuating rod while still being displaceable. Before the fixing, the position of the actuating device which corresponds to the closed position is set by application of the corresponding voltage to the electric actuating device. Subsequently, a prestressing force is applied to the coupling element coaxially with respect to the actuating rod via a pneumatic actuator.

  • Publication number: 20140366544
    Abstract: A gas turbine engine combustor includes an exit duct having annular first and second exit duct walls radially spaced apart to define therebetween the combustor exit opening. The first and/or second exit duct walls has a double-skin wall section which includes an inner hot wall facing the combustor exit opening and an outer cold wall fastened to the inner hot wall and radially spaced away therefrom to define a radial gap therebetween. The outer cold wall has a coefficient of thermal expansion greater than that of the inner hot wall. This helps reduce thermal growth mismatch between the outer cold wall and the inner hot wall during operation of the combustor, and reduces thermal stress at the joint between the hot and cold walls.
