Apparatus for feeding speciments into evacuated chambers |
| abstract |
APPARATUS FOR FEEDING SPECIMENS INTO AN EVACUATED CHAMBER COMPRISES A VACUUM LOCK HAVING A SPECIMEN CARRIER PISTON MOVABLE WITHIN A GAS-TIGHT CYLINDER BETWEEN A FIRST POSITION AT WHICH THE SPECIMEN IS INSERTED IN A SPACE IN THE CARRIER, A SECOND POSITION AT WHICH THE CARRIER SPACE IS EXPOSED TO A ROUGH VACUUM, AND A THIRD POSITION AT WHICH THE CARRIER SPACE COMMUNICATES WITH THE HIGH VACUUM OF THE CHAMBER FOR THE DISCHARGE OF THE SPECIMEN. IN COMBINATION WITH THIS VACUUM LOCK, SUCH APPARATUS CAN INCLUDE A SPECIMEN STORAGE AND TRANSFER DEVICE IN THE FORM OF A MAGAZINE INTO WHICH THE SPECIMENS ARE DEPOSITED FROM THE VACUUM LOCK AND WHICH IS ROTATABLE WITHIN A HOLLOW COMPARTMENT COMMUNICATING WITH THE SAID EVACUATED CHAMBER FOR THE TRANSFER AND DISCHARGE OF THE SPECIMEN. |
