Apparatus such as a furnace muffle (11) for use in a CVI/CVD furnace. The apparatus includes a bottom (12), a top (13), and an outer wall (3) defining an interior space (1) in the apparatus, and a passive heat distribution element (7, 9) located within the interior space (1) and apart from the outer wall (3). Preferably, the bottom (12) and top (12) include perforated plates and the outer wall (3) is cylindrical in shape and all are made of graphite or carbon-carbon composite material and the passive heat distribution element (7, 9) is cylindrical in shape and includes graphite or carbon-carbon composite discs having no spacers therebetween. Also, a method for densifying a porous carbon preform (5), which method includes the steps of: (a) providing the apparatus (11); (b) charging the apparatus (11) with a plurality of stacks of annular porous carbon preforms (5), the preforms being separated from one another by spacers (15); (c) locating the charged apparatus (11) in a furnace at a temperature in the range of 950-1100° C. and a pressure in the range of 5-40 torr; and (d) circulating a natural gas reactant blended with up to 15% propane through the apparatus for 150-900 hours. Also, a batch of carbon-carbon composite preforms made by the method, wherein the density of the batch of preforms is at least 0.5 g/cc higher than the density of a batch of preforms made by an otherwise identical process in which the apparatus does not contain a passive heat distribution element located within its interior. The preforms may be configured as aircraft landing system brake discs or racing car brake discs.

A vane assembly for a gas turbine engine is disclosed having lower thermally induced stresses resulting in improved component durability. The stresses in the vane assembly airfoils are lowered by increasing the flexibility of the vane platform and reducing their resistance to thermal deflection. This is accomplished by placing an opening along the vane assembly rail that reduces the effective stiffness of the platform, thereby lowering the operating stresses in the airfoils of the vane assembly. A removable seal is then placed in the opening in order to prevent undesired leakages, while maintaining the benefit of the increased platform flexibility.

摘要:
A flashlight including a longitudinal barrel and a head with an angular connector between the longitudinal barrel and the head. The angular connector is rotatable about the longitudinal axis thereby to direct the head in different radial directions relative to the barrel. The connector is also removable so that the head can be directly connected to the barrel. A finger operable toggle on the switch permits operation of the flashlight between the on and off positions, and the contact with the switch permit operation irrespective of the angular position of the angular connector

Upgrades to the full version are enabled by setting a flag once the customer has paid for the upgrade. The customer is able to play one level or track for a game or to play the,game for limited period of time. Once the trial limit is reached, the content or game provider offers details on how to purchase the full version.
摘要:
A gas turbine engine (40) having an active combustion control system (54) including a sensor element (44) positioned proximate the combustion chamber (46) as part of a sensor assembly (84) including a spring-action bellows (74). The sensor assembly is installed through an opening (69) in the casing (48) of the engine to make contact with the combustor wall (62). The bellows is compressed from its resting position by tightening mounting bolts (70) against a mounting flange (66) of the sensor assembly. The spring action of the bellows ensures contact between the sensing assembly and the combustor wall in spite of differential thermal growth between the casing and the combustor. The sensor element may be replaced by simply removing the mounting bolts without further disassembly of the engine.
