Valve sealing method

Claim 1

A VALVE SEALING METHOD FOR SELECTIVELY HERMETICALLY SEALING AN APERTURE DEFINED BY A CONSTRICTION LOCATED INTERMEDIATE NECK AND TANK PORTIONS OF A CAPSULE TO PROVIDE INTERCONNECTION OF SAID CAPSULE AND A LIGHT VALVE TUBE WHILE MAINTAINING HERMETIC ISOLATION THEREBETWEEN AND FOR REMOVING SAID HERMETIC SEAL TO ENABLE THE TRANSFER OF WRITING FLUID FROM WITHIN SAID TANK PORTION OF SAID CAPSULE TO A RESERVOIR WITHIN SAID LIGHT VALVE TUBE, COMPRISING THE STEPS OF: (A) PROVIDING A HOLLOW SIDE ARM ON SAID NECK PORTION AND IN COMMUNICATION THEREWITH AT A POSITION REMOTE FROM SAID CONSTRICTION, (B) POSITIONING A VALVE MEMBER AND VISCOUS SEALING FLUID WITHIN SAID SIDE ARM, SAID SEALING FLUID RETAINING SAID VALVE MEMBER WITHIN SAID SAID ARM, (C) INTRODUCING SAID WRITING FLUID INTO SAID TANK PORTION, (D) CONNECTING SAID CAPSULE AT SAID NECK PORTION THEREOF TO AN EVACUATING MEANS FOR DEGASSING SAID CAPSULE AND SAID WRITING FLUID, (E) HEATING SAID SIDE ARM FOR RENDERING SAID SEALING FLUID FLUENT, (F) TILTING SAID CAPSULE TO EXTRICATE SAID VALVE MEMBER FROM SAID SIDE ARM, (G) TRANSFERRING SAID VALVE MEMBER TO SAID CONSTRICTION IN PLUGGING RELATIONSHIP THEREWITH, (H) HEATING SAID SEALING FLUID AND CAUSING IT TO FLOW INTO SEALING RELATION WITH SAID VALVE MEMBER AND SAID CONSTRICTION, (I) COOLING SAID SEALING FLUID FOR COMPLETING THE HERMETIC VALVE SEAL, (J) INVERTING SAID CAPSULE FOR POSITIONING SAID NECK PORTION THEREOF BELOW SAID TANK PORTION AND CONNECTING SAID CAPSULE IN HERMETICALLY SEALED FASHION WITH SAID RESERVOIR, (K) EVACUATING AND DEGASSING SAID LIGHT VALVE TUBE, (L) HEATING SAID SEALING FLUID FOR RENDERING IT FLUENT TO ENABLE RELEASE OF SAID VALVE MEMBER FROM SAID CONSTRICTION, (M) RETAINING SAID VALVE MEMBER, FOLLOWING THE REMOVAL THEREOF FROM SAID CONSTRICTION, WHILE TRANSFERRING SAID WRITING FLUID TO SAID RESERVOIR.
