Abrégé

An ignitor that includes at least one layer of silicon dioxide coating a silicon carbide material, methods of making and using the ignitor, and a kit that includes the ignitor are provided. The silicon dioxide coating is not intended to be removed prior to use. Rather, it is intended to remain on the ignitor during use.

Abrégé

A water hammer mitigation device (100) includes an inlet (102), an outlet (104), an expansion housing (106), and a deflector (136). The inlet (102) receives fluid from a source. The outlet (104) passes the fluid to a destination. The expansion housing (106) is disposed between the inlet (102) and the outlet (104). The expansion housing (106) defines an internal expansion chamber (132) having an expansion volume sufficient to hold a plurality of volume units of the fluid. Each volume unit is defined by a fluid flow volume over a duration of time. The deflector (136) is disposed within the expansion chamber (132). The deflector (136) substantially redirects a backward energy pulse, which enters the expansion chamber (132) through the outlet (104), away from the inlet (102).

Abrégé

The present invention provides a ceramic to ceramic joint and methods for making such a joint. Generally, the joint includes a first (15) ceramic part and a second (20) ceramic part, wherein the first (15) and second (20) ceramic parts each include a ceramic-carbide or a ceramic-nitride material. In some cases, an aluminum-initiated joint region joins the first (15) and second (20) ceramic parts. This joint region typically includes chemical species from the first (15) and second (20) ceramic parts that have diffused into the joint region. Additionally, the first (15) and second (20) ceramic parts each typically include a joint diffusion zone that is disposed adjacent to the joint region and which includes aluminum species from the joint region that have diffused into the joint diffusion zone. Other implementations are also described.

Abrégé

An igniter shield is provided that is used with an igniter. The igniter shield includes a mounting base, proximal portion, a baffle, longitudinal supports, and a distal portion, wherein the baffle has a radius of curvature that is smaller than a radius of curvature of the proximal or distal portions of the igniter shield. In an embodiment, the baffle directs gas flow in a substantially circular motion toward the igniter, thereby creating turbulence in the gas stream to provide improved combustion efficiency.

Abrégé

A bushing system includes a bushing having a bottom plate with a plurality of holes from which filaments are drawn. At least one elongated support extends through the bushing generally along a longitudinal axis to hold and stabilize the bushing. To handle the harsh conditions under which the bushing is subjected, the support comprises an alumina-based ceramic that generally resists sagging or excessive expansion and contraction during heating and cooling.
