摘要： A hardware assembly is provided for controlling a first portion of gas and a second portion of gas in a furnace. The first portion of the gas is introduced to a center opening region of a stack of porous structures. The second portion of the gas is introduced to an outer region of the stack of porous structures. Most of the gas flows out of the hardware assembly from either the center opening region or the outer region while some of the gas flows out through small holes from the other region. A densification method is also provided with two densification processes in which the gas flows in opposite directions in the two densification processes.

摘要： A method of chemical vapor infiltration and deposition includes stacking a number of porous structures in a stack in a furnace. The stack has a center opening region extending through the porous structures and an outer region extending along the porous structures. A first portion of a reactant gas is introduced to the center opening region. A second portion of the reactant gas is introduced to the outer region. The first portion and the second portion are controlled proportions thereby introducing predetermined portions of the reactant gas to both the center opening region and the outer region. The change in weight of the entire furnace, including contents, is measured during the chemical vapor infiltration and deposition process. The rate of weight change is monitored.

摘要： The invention is a device for positioning a hand-held RAM inspection system for measuring the thickness of a RAM coating. In detail, the invention includes a housing containing the RAM coating inspection system, the housing having a longitudinal axis. Three laser distance-measuring devices are circularly mounted on the housing at 120 degrees from each other; the laser distance measuring devices are for determining the required distance and orientation of the RAM inspection system from the RAM coating surface. An electrical controller circuit is coupled to the three lasers and the RAM inspection system for triggering the RAM inspection system to measure the RAM material when the three lasers indicate that the housing is at the proper distance and orientation to the RAM coating surface.
