  • Patent number: 10201845
    Abstract: The invention relates to a device and a corresponding method for manufacturing brush seals with obliquely positioned bristles. The method comprises the following steps: As the first step, a metal filament or wire (50) comprising a material for bristles is wound over two wire cores (42, 46) disposed at a distance from and running parallel to one another, to form a tightly packed metal filament or wire package (48). As the next step, the metal filament or wire package (48) is fastened to at least one wire core (42, 46). Then the region around at least one of the two wire cores (42, 46) is locally heated. Subsequently, at least one of the two wire cores (42, 46) is displaced.

  • Publication number: 20150129647
    Abstract: An electrically conductive lead is formed using a bonding tool. After bonding the wire to a metal surface and extending a length of the wire beyond the bonding tool, the wire is clamped. Movement of the bonding tool imparts a kink to the wire at a location where the wire is fully separated from any metal element other than the bonding tool. A forming element, e.g., an edge or a blade skirt provided at an exterior surface of the bonding tool can help kink the wire. Twisting the wire while tensioning the wire using the bonding tool can cause the wire to break and define an end. The lead then extends from the metal surface to the end, and may exhibits a sign of the torsional force applied thereto.

  • Publication number: 20150132601
    Abstract: A method of depositing a multi-layer cladding (40) of superalloy material and an apparatus so formed. A first layer of material (20) is deposited on a substrate (22) such as by laser cladding of superalloy powder (54). The deposited material includes a directionally solidified region (24) and a topmost equiaxed region (26). The topmost region is removed such as by grinding to expose a flat surface (28) of directionally solidified material. A second layer of material (32) deposited onto the exposed flat surface will again have a directionally solidified region (34) and a topmost equiaxed region (36). The process is repeated until a desired thickness of cladding material is achieved, the multi-layer cladding having no equiaxed material between its layers throughout its thickness.

The process effectively utilizes features of a CVD coating, which renders a tool service life longer and enables a drill head more suitable for high-speed cutting to be manufactured. A cutting tip having been CVD coated with a hard material is brazed at a brazing temperature to a predetermined portion at a distal end side of a head main body. An outer diameter portion OD of the brazed tip about a rotation axis of the head main body is polished. Then, the cutting tip and the head main body are PVD coated with a hard material at a second temperature lower than the brazing temperature.

In an exemplary embodiment, a free end of a wire stem is bonded to a contact area on a substrate, the wire stem is configured to have a springable shape, the wire stem is severed to be free-standing by an electrical discharge, and the free-standing wire stem is overcoated by plating. A variety of materials for the wire stem (which serves as a falsework) and for the overcoat (which serves as a superstructure over the falsework) are disclosed.

    Abstract: A method for joining a tube and tube plate for use in a tube-and-shell heat exchanger is disclosed. The method enables a joint between the tube and tube plate that is substantially hermetic and substantially corrosion-resistant. The method comprises providing an anvil inside the tube, wherein the anvil supports the tube wall during a friction-stir welding process used to join the tube and tube plate. The anvil facilitates formation of a reliable weld region and enables faster friction-stir welding.

  • Publication number: 20100200262
    Abstract: A packaging system having a housing for providing a hermetically sealed interior space for receiving and supporting optoelectronic components. The housing has at least one section of wall comprising a layer of liquid crystal polymer (LCP). At least one hermetically sealed electrical port is formed in the LCP wall section over a predetermined area and comprises a layer of metal adhered to and overlying the predetermined area on the of the LCP wall section. An electrode passes through the metal from the exterior of the system to the interior space to provide an electrical communication path between the optoelectronic components and the exterior of said packaging system. A solder joint is formed between the electrode and the layer of metal to provide a hermetic connection between the layer of metal and the electrode to assure that the hermeticity of the housing remains unchanged with the electrical port present.

    Abstract: At least one section of the screw (11) has a wear-protection layer (13) and at least one other section of the screw preferably has an anti-friction layer (18). In a solid rod (11?), abed (12) for the wear-protection layer (13) is first formed, and in this the wear-protection layer (13) is then applied, and finally the interstices (14) between the screw flights (15) are formed. According to the invention, the wear-protection layer (13), for example composed of tungsten carbide, is applied by build-up welding, and the interstices (14) are formed with lateral separation (16, 16?) with respect to the wear-protection layer (13). For production of the anti-friction layer, the dimension of that/those section(s) of the screw (11) where the anti-friction layer, e.g. composed of molybdenum, is to be applied is reduced below specification, while providing lateral separation (19) with respect to the wear-protection layer. The anti-friction layer is then applied in the under-dimensioned region (17).
