Claim 1
Independent Claim
212 words
IN A RATE GYROSCOPE HAVING A CASE, A GIMBAL ASSEMBLY, AND A TEMPERATURE COMPENSATING MECHANISM COMPRISING IN COMBINATION, A DAMPING FLUID IN THE CASE, A CYLINDRICAL ROTATABLE MEMBER OPERATIVELY CONNECTED TO THE GIMBAL ASSEMBLY IN THE CASE AND HAVING AN AXIALLY ALIGNED CHANNEL IN ITS OUTER SURFACE, THE ROTATABLE MEMBER BEING POSITIONED WITHIN THE CASE SO THAT A FIRST FLUID PATH OF PROVIDED BETWEEN ITS OUTER SURFACE AND THE CASE, AND A STATIONARY PADDLE ATTACHED TO THE CASE AND PROJECTING INTO THE SAID CHANNEL, THE SAID PADDLE FORMING THE CHAMBERS WITH THE SIDEWALLS OF THE CHANNEL, AND THE SAID PADDLE PROVIDING A SECOND FLUID PATH BETWEEN ITS FREE END WITHIN THE CHANNEL AND THE SAID OUTER SURFACE OF THE ROTATABLE MEMBER, WHEREIN THE STATIONARY PADDLE COOPERATES WITH BOTH SIDE WALLS OF THE SAID CHANNEL TO PUMP THE FLUID UPON ROTATION OF THE ROTATABLE MEMBER FROM ONE OF THE SAID CHAMBERS TO THE OTHER CHAMBER THROUGH THE SAID SECOND FLUID PATH, AND WHEREIN THE ROTATABLE MEMBER HAS A HIGH COEFFICIENT OF EXPANSION RELATIVE TO THAT OF THE CASE AND IS SELFEXPANDABLE WITH A RISE IN TEMPERATURE OF THE FLUID, SO THAT THE SIZE OF THE FLUID PATHS ARE NARROWED BY THE RELATIVE EXPANSIONS OF THE ROTATABLE MEMBER AND THE CASE UPON SUCH TEMPERATURE.
