Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
200 words
A method of inhibiting the transmission of vibration from a cryogenic refrigerator to an adjacent cryogenic detector apparatus to which the refrigerator is operatively interconnected, comprising: mounting one side of the cryogenic refrigerator to a base plate and mounting said cryogenic detector apparatus to the same base plate through a beam support extending from the base plate to the detector; providing in the mounting of the refrigerator a first layer of an elastomeric interface between the refrigerator and the base plate; and providing in the mounting of the cryogenic detector, a second layer of an elastomeric interface between the beam support for the detector apparatus and the mounting of the beam support extending from the base plate; providing a damping mass adjacent a side of the refrigerator opposite the one side mounted to the base plate and providing in the mounting of said damping mass to the opposite side of the refrigerator a further layer of an elastomeric interface between the opposite side of the refrigerator and the damping mass; whereby the refrigerator and the detector are mounted as masses in a mass/elastomeric/mass elastomeric/mass series springed system to produce an essentially apparently motionless relationship between the refrigerator and the detector.
Claim 2
Independent Claim
200 words
A method of inhibiting the transmission of vibration from a cryogenic refrigerator to an adjacent cryogenic detector apparatus to which the refrigerator is operatively interconnected, comprising: mounting one side of the cryogenic refrigerator to a base plate and mounting said cryogenic detector apparatus to the same base plate through a beam support extending from the base plate to the detector; providing in the mounting of the refrigerator a first layer of an elastomeric interface between the refrigerator and the base plate; and providing in the mounting of the cryogenic detector, a second layer of an elastomeric interface between the beam support for the detector apparatus and the mounting of the beam support extending from the base plate; providing a damping mass adjacent a side of the refrigerator opposite the one side mounted to the base plate and providing in the mounting of said damping mass to the opposite side of the refrigerator a further layer of an elastomeric interface between the opposite side of the refrigerator and the damping mass; whereby the refrigerator and the detector are mounted as masses in a mass/elastomeric/mass elastomeric/mass series springed system to produce an essentially apparently motionless relationship between the refrigerator and the detector.
Claim 3
Dependent Claim
38 words
The method of claim 1 including the supperssion of the transmission of vibration from the refrigerator to the detector at the point of their operative interconnection by providing a heat wick connection between the refrigerator and the detector.
