Claims24
A method of sealing a laminate assembly comprising:
- preloading a laminate assembly having a plurality of laminations with a first tie rod arrangement, the first tie rod arrangement extends through a channel in a housing and moves freely through the channel in an axial direction relative to the housing, wherein the first tie rod arrangement is mechanically separated from the housing;
- pressurizing the laminate assembly;
- and
- pressurizing an enclosed volume disposed adjacent an end portion of the laminate assembly to hold the laminations in sealed positions, wherein the enclosed volume is partially defined by the housing.

A method of sealing a laminate assembly comprising:
- preloading a laminate assembly including a plurality of laminations with a first tie rod arrangement, the laminate assembly is disposed between opposing endplates, one of the opposing endplates supports the laminate assembly and the other of the opposing endplates establishes a portion of an enclosed volume, the first tie rod arrangement secured to at least one of the opposing endplates, wherein the first tie rod arrangement extends a first length and the second tie rod arrangement extends a second length, the second length greater than the first length;
- using a second tie rod arrangement different from the first tie rod arrangement to hold a housing relative to the laminate assembly, the housing establishing the enclosed volume with one of the opposing endplates;
- pressurizing the laminate assembly;
- and
- pressurizing the enclosed volume disposed adjacent an end portion of the laminate assembly to hold the laminations in sealed positions.

A method of sealing a laminate assembly comprising:
- preloading a laminate assembly having a plurality of laminations;
- pressurizing the laminate assembly;
- and
- pressurizing a first enclosed volume disposed adjacent a first end portion of the laminate assembly and a second enclosed volume disposed adjacent a second end portion of the laminate assembly to hold the laminations in sealed positions, using a first tie rod arrangement to hold the second enclosed volume relative to the laminate assembly, using a second tie rod arrangement to hold the first enclosed volume relative to the laminate assembly, wherein the first tie rod arrangement only holds the first enclosed volume relative to the laminate assembly.
