GASKET Russian patent published in 2008 - IPC F16D69/02 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to components used for separation of stacked porous plates in production process. Proposed circular gasket has opposed first and second surfaces with multiple holes. The said gasket is made of metal wire screen and partially form multiple radial gas-passages, each passing between the gasket inner and outer radial sides to inter-joint them. Method of preparing circular carbon fiber blanks for chemical filtration in vapor phase consists in stacking the aforesaid carbon fiber blanks. Between every two circular blanks, a circular metal screen cushion is laid so as to make stacked circular blanks and circular gaskets form interfaces of internal space inside a stack. Every circular gasket has first and second opposed surfaces and is made so as to form multiple radial gas passages communicating the stack inner space with outside space.

EFFECT: updating production process.
