A method of attaching functional components to a roof element of a vehicle is provided. The method including the steps of: applying a curable material in a low-viscosity state which is molded in sections by a first mold surface, wherein a second mold surface is used for further shaping sections of the curable material, and wherein an opening remains accessible towards an environment through which the curable material is introduced.

A method for improving the operational life of production parts, such as steel sucker rods, couplings, pump parts, and tubes, for use in underground recovery or production of oil and gas, includes coating the steel production parts with a layer of corrosion resistant alloy (CRA) to reduce a loss rate of the steel by improving corrosion resistance and mitigate pitting. In one embodiment, the corrosion resistant alloy is a nickel-based alloy. In other embodiments, the steel production parts can either be coated with an epoxy / phenolic layer, or coupled with a sacrificial anode. The coating process can implemented by any one of the following processes: cold spray coating; electroless corrosion resistant coating; flow forming; and electrochemical machining.

The invention is related to an ultrasonic welding device (5) comprising: an adapter frame (6); an ultrasonic horn (7) driven by a adapter frame mounted converter (8). A pick member (9) comprises grippers (11-14). Passive clamping means are provided with a press pad (10). Control means and activation means (15) are provided for controlled activation of the pick member (9) and the ultrasonic horn (7). The invention is further related to a method of operating said device.

A method for forming a tubular body, comprising the following steps: making available a tubular body having a first and a second tube end, filling the tubular body with a liquid, closing the tubular body, and forming the tubular body.

A brazed part, and methods of forming a brazed joint therein, are disclosed. The brazed part includes two or more components that are brazed together. Using the method of locating the parts herein disclosed, an inter-component gap between the components may be formed. Flow control features formed along the inter-component gap may then be used to assist in the retention of the braze material between the components during brazing.

The present invention relates to a method for the manufacture of a composite article comprising a composite plate (1) and at least one fitting (4). The method is characterized by the steps of arranging at least one former on said composite plate (1), arranging at least one fitting (4) on said composite plate (1), producing a lay-up by applying a composite material layer (9) least partly covering an external surface of the former and of the fitting, and curing the layup in a curing process. After curing, said composite material layer (9) forms the walls of a stiffener and at least partly encloses the fitting so as to support it in a predetermined position.

The present invention relates to a flexible package-forming machine for horizontal packaging and method of manufacturing flexible packages. The proposed forming machine consists of an unwinding unit (11), a perforating unit (12), a folding unit (14), a welding unit (16), and a cutting unit (17), wherein a compensating unit (13) is further included intercalated between the perforating unit (12) and the folding unit (14), linking a section with intermittent forward movement (S1) of the flexible band (1) where the flexible band moves in an intermittent manner and including the perforating unit, and a section with continuous forward movement (S2) where the flexible band moves in a continuous manner and including the folding unit, flexible band being accumulated in said compensating unit during the forward movement of the section with intermittent forward movement (S1) and the accumulation being reduced during breaks in the forward movement of the section with intermittent forward movement.

An investment casting pattern including: a consumable body formed of: a first body portion; and a second body portion; and a fastener arranged to form an interface between the first body portion and the second body portion, and to locate the first body portion relative to the second body portion, wherein the fastener is formed of a different material than the first body portion and the second body portion.
