Abstract: A shaped plastic exhaust system for a fuel cell vehicle. In one embodiment, the exhaust system employs integrally molded bundle clips that support vehicle brake lines and/or a fuel supply line. An exhaust flow section can be formed into any suitable shape for a particular vehicle design, including a flat rectangular shape giving the exhaust system a low profile. The integral bundle clips can be provided every so often along the exhaust flow section, or can extend the complete length of the exhaust flow section.

Abstract: A thermal pressure relief device (TPRD) is shown and includes a housing having a first end with a first aperture and a second end having a second aperture. The first and second apertures are configured to allow a fluid to flow through the housing. The TPRD includes a trigger member, such as a ball, disposed within the housing. The ball is seated laterally within a retainer. The retainer includes a rim forming a seat for supporting the ball within the housing. The movement of the ball from the first closed position laterally seated within the retainer to the second open position descended within the retainer is caused by an expansion of the rim of the retainer. The rim of the retainer is formed substantially of a temperature sensitive material adapted to expand volumetrically with an increase in temperature. The temperature sensitive material can expand linearly or non-linearly.

Abstract: A fuel cell vehicle is provided with a temperature tolerant exhaust system that eliminates the need for exhaust pipes, pipe routing, support systems, and ground clearance issues. The exhaust system includes a fuel cell exhaust pipe in fluid communication with a fuel cell stack and an exhaust tube. The exhaust tube is supported within an exhaust channel that extends along and forms a part of the underbody of the fuel cell vehicle. Alternatively, the exhaust tube is formed within the interior of the exhaust channel.

Abstract: A method for manufacturing a pressure vessel is provided. The method includes the steps of: providing the pressure vessel and a first temperature-pressure relief device, the temperature-pressure relief device having a housing; affixing the first temperature-pressure relief device to the pressure vessel; and forming a vent hole in the housing of the first temperature-pressure relief device after affixing the first temperature-pressure relieve device to the pressure vessel. The vent hole is selectively oriented in a desired direction via the method for manufacturing the pressure vessel. Temperature-pressure relief devices for vent hole alignment and selective orientation are also provided.

Abstract: In a method for producing at least one surface on a workpiece by a material removal tool and a corresponding material removal device, the surface is produced quickly and at low cost. Based on any surface to be produced, a movement path of the material removal tool is controlled to produce a ruled surface approximating to the surface, the movement path being provided in the form of a curve on a dual unit sphere, wherein a curve point corresponds to a location and an orientation of the removal tool. The curve can be produced based on ruling lines, which are converted into points, interpolated by a dual sphere spline interpolation algorithm, on the dual unit sphere by mathematical transformations. The curve can then be transformed back or can be used directly to follow the material removal tool. Likewise, directrix curves can be determined by the dual sphere spline interpolation algorithm.

Abstract: A tube fitting assembly is provided that includes a tube having a laterally outwardly extending flange formed adjacent an end thereof and a nipple portion between the flange and the end of the tube. A sealing member is disposed on and circumscribes the nipple portion of the tube. A gland nut is provided that includes an opening therethrough to receive the tube. The gland nut is adapted to be releasably coupled to a coupling member. The coupling member includes a counter bore formed therein to receive the sealing member and the nipple portion of the tube, wherein the gland nut abuts the flange of the tube to substantially secure the sealing member and the nipple portion within the counter bore to form a substantially fluid tight seal between the tube and the coupling member.

Abstract: A process for forming and/or modifying dielectric films on semiconductor substrates is disclosed. According to the present invention, a semiconductor wafer is exposed to a process gas containing a reactive component. The temperature to which the semiconductor wafer is heated and the partial pressure of the reactive component are selected so that, sometime during the process, diffusion of the reactive components occurs through the dielectric film to the film/semiconductor substrate interface. Further, diffusion also occurs of semiconductor atoms through the dielectric film to an exterior surface of the film. The process of the present invention has been found well suited to forming and/or modifying very thin dielectric films, such as films having a thickness of less than 8 nm.

Abstract: A method of coupling a tool to a length of tubular comprises securing the tool in a basket; lowering a tong arrangement having a rotary part and a stationary part, relative to the basket to engage respective locking members of the tong arrangement and the basket, thereby fixing the basket and the tool relative to the stationary part of the tong arrangement; and rotating the length of tubular using the rotary part of the tong arrangement so as to couple the tool to the length of tubular. A torque measuring flange may be associated with the tong arrangement. The torque measuring flange comprises a top plate and a bottom plate and one or more cylinders disposed between one or more wedges, whereby rotating the top plate causes the wedges to compress a piston in the cylinder.
