Abstract: A gas turbine air intake system uses a filter element having a seal member with radial projections and radial recesses. The seal member forms a seal with components on the tube sheet of the system and at the end opposite of the tube sheet. At the end opposite of the tube sheet, there can be an assembly cover, or alternatively, an additional filter cartridge.

Abstract: A chip stack comprising a flex circuit including a flex substrate having a first conductive pattern disposed thereon and a plurality of leads extending therefrom. Also included in the chip stack are at least two integrated circuit chip packages. The integrated circuit chip packages may be electrically connected to the first conductive pattern of the flex circuit such that the integrated circuit chip packages are positioned upon respective ones of opposed top and bottom surfaces of the flex substrate. Alternatively, one of the integrated circuit chip packages may be positioned upon the top surface of the flex substrate and electrically connected to the first conductive pattern, with the remaining integrated circuit chip package being attached in a non-conductive manner to the bottom surface of the flex substrate such that the conductive contacts of such integrated circuit chip package and the leads collectively define a composite footprint for the chip stack.

Abstract: A connector for use in a chip stack including at least first and second stacked packaged chips which each comprise a package body having a plurality of leads extending therefrom. The connector comprises a substrate which is preferably fabricated from an insulating material. Attached to the substrate are a plurality of flex tabs which extend in spaced relation to each other, and are each preferably fabricated from a conductive material such as aluminum. The flex tabs are each shaped to define an arcuately contoured first portion which is electrically connectable to a respective one of the leads of the first packaged chip, and an integral, generally flat second portion which extends along a portion of the substrate and is electrically connectable to a corresponding one of the leads of the second packaged chip.
