Abstract: Provided is a device configured for attachment to a lighting fixture. The device includes an engagement mechanism that allows the lighting fixture to be mounted within a recess of a substantially flat surface. The engagement mechanism is constructed to facilitate movement of a tension mechanism from a maximum tension position to a minimum tension position. Movement of the engagement mechanism is in response to an applied force generated by contact of the engagement mechanism with a first side of the substantially flat surface. Also provided is a method for mounting the lighting fixture using the engagement mechanism.

Abstract: Provided is a system for attachment to a lighting fixture including lens components within a recess of a substantially flat surface. The system includes a tension mechanism configured for rotatable movement in response to an applied force. The system also includes a tether configured to provide the applied force and facilitate movement of the tension mechanism from a minimum tension position to a maximum tension position. The tether attaches to the tension mechanism and is assessable at a position approximate to the lens components of the lighting fixture. Also provided is a method for mounting the lighting fixture using the tension mechanism engaged by the tether.

Abstract: The present invention provides a plasma transferred wire arc torch assembly that includes a monolithic block assembly that combines into a single component several features that have previously been separate components. The monolithic block of the present invention combines the functions of a wire guide, an air baffle, and a nozzle. Integration of this components allows for a reduction in size of the plasma transferred wire arc torch assembly thereby making it possible to coat smaller diameter bores with metal.

Abstract: The present invention provides a nonflammable ternary gas mixture to be used in a plasma machining operation. The ternary gas mixture of the present invention comprises from about 4% to about 6.2% hydrogen, 30% to 50% argon, and the balance nitrogen. In another embodiment of the present invention, a method of generating a high pressure plasma is provided. The method of this embodiment comprises introducing the ternary gas mixture of the present invention into a plasma torch apparatus, initiating a plasma in the plasma torch apparatus, and sustaining the plasma with a high voltage between a cathode and an anode.

Abstract: A cathode assembly 10 for an electric arc spray apparatus. The cathode assembly 10 utilizes a positive cathode retention design which provides for improved heat management characteristics, quick and easy cathode replacement and increased cathode life. The cathode assembly includes a cathode holder 14, a cathode 12 including a first portion 26 which resides within the cathode holder 14, a tip portion 28 which extends from the cathode holder, and a shoulder portion 33 which is formed on the outer surface of the cathode. The cathode assembly 10 further includes a retention member or nut 16 which removably attaches to the cathode holder 14 and which engages the shoulder portion 33, effective to positively retain the cathode 12 within the holder 14. The retention member 14 also includes an aperture through which the cathode tip 28 extends.

Abstract: A method and system for machining a cylinder head include loading a cylinder head into a first five axis computer numerically controlled (CNC) machine. A first fixture of the first CNC machine is then located against a top surface of the cylinder head such that the cylinder head is in a horizontal position. The first CNC machine then machines the cylinder head in the horizontal position. A second fixture of the first CNC machine is then located against a bottom surface of the cylinder head such that the cylinder head is in a vertical position. The first CNC machine then machines the cylinder head in the vertical position. The cylinder head is then moved into a second five axis CNC machine. A fixture of the second CNC machine is then located against a bottom surface of the cylinder head. The second CNC machine then machines the cylinder head.
