Abstract: An assembly for installation of a switch in the dashboard of a vehicle without the use of any tools. The assembly comprises a housing, a resilient member such as a washer spring, and a bezel. The switch is secured to the housing and subsequently inserted into the bezel which is integrated with the dashboard. The installation of the switch, which is secured to the housing is then completed through the interaction of a profiled wall on the bezel and a flange on the housing with the washer spring interposed between.

Abstract: The repair of cracks according to the state of the art comprises the fact that defects located on the inside must be worked outward in order to be able to be welded closed. The method according to the invention proposes not to work out cracks located on the inside, but to melt the crack located on the inside utilizing a flux agent.

Abstract: A method of stress relief for stainless steel combustion turbine components includes vibrating the components during welding at a subharmonic frequency. The proper frequency is selected to be below a harmonic frequency, and to produce an amplitude in the range of ¼ to ½ the amplitude produced by a harmonic frequency. The component to be repaired is vibrated during and after welding at this frequency.

Abstract: A method for welding superalloy components at ambient temperature conditions while reducing the propensity of the superalloy material to crack as a result of the weld. A root pass region of the weld is formed using a filler material that exhibits ductility that is higher than that of the base superalloy material. The ductile material mitigates stress in the root region, thereby preventing the formation of cracks. A remaining portion of the weld is formed using a filler material that essentially matches the base superalloy material. The method may utilize a pre-weld heat treatment to grow a gamma prime precipitate phase in the superalloy material, a chill fixture to remove heat during welding, a relief cut to reduce stress in the root region, and a conventional post-weld heat treatment.
