Abstract: Systems (100) and methods (1500) for using a pressure vessel. The methods comprise: obtaining the pressure vessel comprising a shell and an insert having an interference fit with the shell whereby the insert is locked in place within the shell via interfacial pressure; inserting at least one electronic component in a first hollow cavity formed in the insert; mechanically supporting the at least one electronic component using a structural feature of the insert; and transferring heat from the electronic component to an external environment via a heat transfer path that comprises a full surface area of the insert's outer surface abutting the shell's inner surface.

Abstract: In the dryer section of a paper machine, the paper web is pressed against the dryer cylinders by means of an air-permeable endless dryer fabric. A ventilator apparatus extends transversely across the paper machine located outside the pocket above and below the fabric turning rolls. Air from the ventilator is forced into the pocket through the fabric in the nips formed by the fabric and the fabric turning roll. This air dilutes the moisture driven from the sheet by the dryer can. The ventilator apparatus also creates a negative pressure region to exhaust air from the pocket. This exhaust air is used to scour the boundary layer of moisture laden air from the incoming fabric. The two-pass ventilator apparatus has two individual chambers separated by an induction chamber. The primary chamber contains multiple air jet nozzles. The blowing directions of the two longitudinal nozzles may be at different angles with respect to the running direction of the dryer fabric.
