Assignee:

Pratt & Whitney Rocketdyne, Inc. - Canoga Park CA

International Classification:

B28B 1/30
B28B 7/32
B28B 23/00

US Classification:

Abstract:

A method for use in manufacturing a ceramic matrix composite article includes assembling a ceramic fiber sheet between a tool and a die, where the tool is conformable to the shape of the die and the melting point of the die is greater than the melting point of the tool. The assembly is then heated to soften the tool. At least one of the tool, the die or a separate inflatable member is then pressurized to conform the tool and the ceramic fiber sheet to the die. Next, the assembly is cooled and the pressure is vented before removal of the tool and ceramic fiber sheet from the die. A preceramic resin with a catalyst is then applied to the ceramic fiber sheet and cured at a curing temperature that is below the melting point of the tool, to form a preform. The tool is then removed from the preform.

US Classification:

239 17

Abstract:

Water display nozzle shields for allowing water display nozzles to be positioned and operated below the surface of the body of water without constant entrainment of water from the body of water affecting the nozzle characteristics. In one embodiment, a rotatable shield assembly is controllably rotatable between first and second positions. In the first position, the shield assembly is positioned over the nozzle of the water display and substantially sealed with respect thereto, the shield extending from adjacent the exit end of the nozzle which is positioned below the water level, to a position above the water level. When rotated to a second position, the nozzle shield, as well as the nozzle, are both disposed below the surface of the water so as to not be visible. In another embodiment, a weighted inflatable member is attached to the nozzle adjacent the exit thereof which, when inflated, will float to the surface of the water to provide a shield functioning as here before described and which, when deflated, will sink below the surface of the water out of sight. Various features of the shields are disclosed.

Abstract:

An electronic automatically decoupling hub assembly is disclosed herein. The assembly has an axle and a hub shell rotationally positioned about the axle. A controller provides automatic activation/deactivation signals to an inductor. The assembly has a bearing rotationally positioned about the axle and a ratchet ring, having a plurality of teeth, rotationally positioned about the bearing. One or more pawls are provided to engage with at least some of the teeth of the ratchet ring and a seal is used to contain the pawls within the assembly. A cassette body assembly is coupled with the ratchet ring and an end cap is used to prevent a contaminant from entering into the decoupling hub assembly.
