Abstract: Repaired spline and seal teeth of a mated component are disclosed. The splines are repaired by using a low energy input weld to deposit a repair material on the non-worn, non-pressure face of the splines while minimizing the HAZ grain size. The splined area of the component is remachined to the original spline contour by removing original material from the worn, pressure face of the splines and excess repair material to produce a mated component with radially re-clocked splines that have original component material on the pressure face of the teeth.

Abstract: A method of repairing spline and seal teeth of a mated component is disclosed. The method includes a low energy input weld to deposit a repair material on the non-worn, non-pressure face of the splines while minimizing the HAZ grain size. The splined area of the component is then remachined to the original spline contour by removing original material from the worn, pressure face of the splines and excess repair material to produce a mated component with radially re-clocked splines that have original component material on the pressure face of the teeth.

Abstract: An overlay for repairing spline and seal teeth of a mated component is disclosed. The overlay is a tube constructed of a weld repair material, the tube having an outer surface and an inner surface. The inner surface is dimensioned to define an aperture sized to receive a plurality of radially spaced splines of the component, the splines of the component arranged to matingly engage a complementary component.

Abstract: An emergency water release device comprises heating elements adapted to heat water, a shower and an eyewash, a valve and a controller which sends a first signal to turn off at least one of the plurality of heating elements when a temperature of the water exceeds a predetermined limit, and when a flow rate of the water is reduced to a reduced flow rate, the valve opens so that water is dispersed away from both the shower and the eyewash in an amount equal to the difference between the flow rate and the reduced flow rate. The heating elements form a first set electrically connected in series which provides heat for water to be dispensed by the shower, a second set electrically connected in series which provides heat for water to be dispensed by the eyewash. The first and second set of heating elements can be connected in parallel. The controller may also be configured to send a signal to another valve to open so that unheated water is mixed with heated water.
