Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
A vibration isolator system comprising a vibration isolator having a closed chamber, a liquid in said chamber, a vapor of said liquid in said chamber, heating means positioned in said chamber for heating said liquid and sensing means for sensing the relative height of said isolator to control the temperature of said liquid in said chamber, said sensing means comprises an adjustable height spring or rigid structure supporting a first contact, a second contact means coupling said contacts to a source of energy and means coupling said heating means to said contacts.
Claim 2
Dependent Claim
92 words
A vibration isolator system comprising a vibration isolator having a closed chamber, a liquid in said chamber, a vapor of said liquid in said chamber, heating means positioned in said chamber for heating said liquid and sensing means for sensing the relative height of said isolator to control the temperature of said liquid in said chamber, said sensing means comprises an adjustable height spring or rigid structure supporting a first contact, a second contact means coupling said contacts to a source of energy and means coupling said heating means to said contacts.
Claim 3
Dependent Claim
109 words
A vibration isolator system comprising a vibration isolator having a closed chamber, a liquid in said chamber, a vport of said liquid in said chamber, heating means positioned in said chamber for heating said isolator to control the temperature of said liquid in said chamber, said sensing means comprises an adjustable height spring structure supporting a first contact, a second contact, a relay coil coupled to said first and second contacts, a source of electrical energy coupled to said coil and one of said contacts, a relay switch controlled by said relay coil, said relay switch closing a circuit between a source of electrical energy and the heating means.
Claim 4
Dependent Claim
109 words
A vibration isolator system comprising a vibration isolator having a closed chamber, a liquid in said chamber, a vport of said liquid in said chamber, heating means positioned in said chamber for heating said isolator to control the temperature of said liquid in said chamber, said sensing means comprises an adjustable height spring structure supporting a first contact, a second contact, a relay coil coupled to said first and second contacts, a source of electrical energy coupled to said coil and one of said contacts, a relay switch controlled by said relay coil, said relay switch closing a circuit between a source of electrical energy and the heating means.
Claim 5
Dependent Claim
80 words
A vibration isolator system comprising a vibration isolator having a closed chamber, a liquid in said chamber, a vapor of said liquid in said chamber, heating means positioned in said chamber for heating said liquid and sensing means for sensing the relative height of said isolator to control the temperature of said liquid in said chamber, said sensing means comprises a displacement sensor means which provides a continuous input signal to control the electrical power provided to said heating means.
Claim 6
Dependent Claim
80 words
A vibration isolator system comprising a vibration isolator having a closed chamber, a liquid in said chamber, a vapor of said liquid in said chamber, heating means positioned in said chamber for heating said liquid and sensing means for sensing the relative height of said isolator to control the temperature of said liquid in said chamber, said sensing means comprises a displacement sensor means which provides a continuous input signal to control the electrical power provided to said heating means.
