The compression air seal for containing air between equipment racks and electronic modules is described incorporating a metal base having a slot opening and an inclined or tapered upper surface with respect to the lower surface, a double layer of elastomeric material having two hardness values one upon the other in enclosing the opening and a coating of low-friction material over the upper elastomeric material to facilitate low friction when an electronic module having a tapered surface is slid over and compresses the seal.

Sliding compression air seal for removable electronic units

A heat dissipating container for electrical components immersed in a liquid dielectric in one chamber and for electrical components surrounded by an air dielectric in another chamber. A flexible bladder serves as a common wall with the liquid dielectric chamber and an air filled recess that is in communication with the air filled chamber to compensate for expansion and contraction of the liquid.
