Abstract
Abstract The invention relates to a method for the operation of an instrument subjected to a radiation, which is protected from the harmful influence of the radiation by means of an auxiliary medium and/or swinging in of a protective shield between source of radiation and instrument. The invention relates further to an apparatus for carrying out this method.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
103 words
An apparatus for protecting an instrument subject to radiation against excessive radiation which comprises a radiation shield movable into a radiation shielding position between the radiation source and said instrument, spring means holding said radiation shield in radiation shielding position, holding means for holding said radiation shield out of said radiation shielding position, a release means operable to deactuate said holding means and thereby bring said radiation shield into said radiation shielding position, cooling means for cooling said instrument and sensor means associated with said cooling means and arranged to operate said release means upon change in the output of said cooling means.
Claim 2
Independent Claim
103 words
An apparatus for protecting an instrument subject to radiation against excessive radiation which comprises a radiation shield movable into a radiation shielding position between the radiation source and said instrument, spring means holding said radiation shield in radiation shielding position, holding means for holding said radiation shield out of said radiation shielding position, a release means operable to deactuate said holding means and thereby bring said radiation shield into said radiation shielding position, cooling means for cooling said instrument and sensor means associated with said cooling means and arranged to operate said release means upon change in the output of said cooling means.
Claim 3
Independent Claim
76 words
The method of protecting a radiation sensitive instrument against excessive radiation which comprises a positioning a protective shield for movement into and out of radiation shielding position with respect to said instrument, directing a fluid coolant at said instrument during such radiation, said fluid coolant being circulated by an electrically energized power source, and positioning said protective shield into radiation shielding position in response to a predetermined decrease in the electrical energization of said power source.
Claim 4
Independent Claim
76 words
The method of protecting a radiation sensitive instrument against excessive radiation which comprises a positioning a protective shield for movement into and out of radiation shielding position with respect to said instrument, directing a fluid coolant at said instrument during such radiation, said fluid coolant being circulated by an electrically energized power source, and positioning said protective shield into radiation shielding position in response to a predetermined decrease in the electrical energization of said power source.
Claim 5
Independent Claim
110 words
An apparatus for protecting an instrument subject to radiation against excessive radiation which comprises a radiation shield movable into a radiation shielding position between the radiation source and said instrument, means including a servo motor holding said radiation shield in radiation shielding position, holding means for holding said radiation shield out of said radiation shielding position, a release means operable to deactuate said holding means and thereby actuate said servo motor to bring said radiation shield into radiation shielding position, cooling means for cooling said instrument and sensor means associated with said cooling means and arranged to operate said release means upon change in the output of said cooling means.
Claim 6
Independent Claim
110 words
An apparatus for protecting an instrument subject to radiation against excessive radiation which comprises a radiation shield movable into a radiation shielding position between the radiation source and said instrument, means including a servo motor holding said radiation shield in radiation shielding position, holding means for holding said radiation shield out of said radiation shielding position, a release means operable to deactuate said holding means and thereby actuate said servo motor to bring said radiation shield into radiation shielding position, cooling means for cooling said instrument and sensor means associated with said cooling means and arranged to operate said release means upon change in the output of said cooling means.
Claim 7
Independent Claim
78 words
An apparatus for the protection of a measuring instrument subject to excessive radiation which comprises a protective shield, positioning means for moving said protective shield into and out of a radiation shielding location with respect to said instrument, coolant circulating means for circulating a fluid coolant in proximity to said instrument, and means actuated by a decrease in the flow of said coolant to operate said positioning means to insert said protective shield into said radiation shielding position.
Claim 8
Independent Claim
78 words
An apparatus for the protection of a measuring instrument subject to excessive radiation which comprises a protective shield, positioning means for moving said protective shield into and out of a radiation shielding location with respect to said instrument, coolant circulating means for circulating a fluid coolant in proximity to said instrument, and means actuated by a decrease in the flow of said coolant to operate said positioning means to insert said protective shield into said radiation shielding position.
Claim 9
Dependent Claim
56 words
An apparatus according to claim 4 in which said positioning means includes a locking mechanism, a conduit through which said coolant circulates, and said means for operating said positioning means being operable upon a decrease in weight of the coolant in said conduit to release said locking mechanism and position said shield in radiation shielding position.
Claim 10
Dependent Claim
52 words
An apparatus according to claim 4 wherein said means for operating said positioning means includes a diaphragm, spring means acting to displace said diaphragm in one direction, means for directing fluid coolant against said diaphragm to displace said diaphragm in the opposite direction, and means coupling said diaphragm to said positioning means.
Claim 11
Dependent Claim
67 words
An apparatus according to claim 4 wherein said means for operating said positioning means includes a cylinder, a piston reciprocable in said cylinder, spring means urging said piston in one direction, means for introducing a portion of said fluid coolant into said cylinder so that its fluid pressure acts on said piston in opposition to said spring means, and means coupling said piston to said positioning means.
Claim 12
Dependent Claim
21 words
An apparatus according to claim 4 in which said protective shield consists of two spaced plates separated by an air gap.
