  • Patent number: 10328775
    Abstract: An exemplary reinforcing element (104) may be configured to be received within a longitudinally extending cavity (C) defined by a structure (102). The reinforcing element may include a base portion (106) having a bonding material (108, 160) applied thereon, and a member (110, 150) selectively secured to the base portion and configured to selectively extend away from the base portion when the reinforcing element is received within the cavity. Accordingly, the reinforcing element may define a first length (L1) when the member is in a first position with respect to the base portion, and a second length (L1+L2) when the member is in a second position extending away from the base portion, the second length being greater than the first length. The selectively extending arrangement of the reinforcing element may generally allow improved ease and accuracy of installing the reinforcing element within a generally closed structure.

  • Patent number: 8658288
    Abstract: A method for manufacturing a porous device with restrictive layer comprises the steps of providing a porous structure having a micro pore structure, flattening the porous carrier to form a surface, and forming a restrictive layer on the surface of the porous carrier, a method for manufacturing said restrictive layer includes forming a nickel-chromium alloy layer on the surface of the porous carrier, forming a copper metal layer on the nickel-chromium alloy layer, forming a nickel metal layer having a top surface on the copper metal layer, and processing said nickel-chromium alloy layer, said copper metal layer and said nickel metal layer to form a plurality of channels communicating with the micro pore structure and the top surface. The restrictive effect and damping effect can raise anti-vibration ability of the porous device itself by formation of dual restrictive structure composed of the micro pore structure and the channels.

  • Publication number: 20140011045
    Abstract: Power generation and transmission components and methods of manufacture are described in which a component is custom designed and produced in discrete layers using computer numerical controlled machining. The design is separated into layers, and the layers are individually machined to impart design features. The layers are then prepared for, and undergo a brazing process in order to build a functionally unitary mechanical component. Components according to the invention include, but are not limited to, engine blocks, cylinder heads, transmission housings, centrifugal pump housings, cylinder blocks, monoblocs (engines in which the cylinder block and cylinder head are formed as one unit), engine crank cases, automotive power train housings and many other large unit or unitary structure components. A commercial method of producing custom components is also described.
