Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
A level compensator for precision and fine balances comprising a balance frame, a balance beam, a support for said beam, a microscale provided on the beam, a screen and a projection apparatus for the reproduction of a section of the microscale on said screen, the level compensator comprising a pendulum on said balance frame, the support axis of the pendulum being arranged parallel to the support axis of said support of said beam, a light reflecting member on the pendulum which deflects the projection light beam, the center of gravity of the pendulum lying above in imaginary horizontal plane comprising the pendulum support axis, and a spring arrangement which acts on the balance frame and on the pendulum beyond the support axis thereof whereby the torque exerted by it on the pendulum counteracts the torque brought about by the center of gravity of the pendulum.
Claim 2
Dependent Claim
145 words
A level compensator for precision and fine balances comprising a balance frame, a balance beam, a support for said beam, a microscale provided on the beam, a screen and a projection apparatus for the reproduction of a section of the microscale on said screen, the level compensator comprising a pendulum on said balance frame, the support axis of the pendulum being arranged parallel to the support axis of said support of said beam, a light reflecting member on the pendulum which deflects the projection light beam, the center of gravity of the pendulum lying above in imaginary horizontal plane comprising the pendulum support axis, and a spring arrangement which acts on the balance frame and on the pendulum beyond the support axis thereof whereby the torque exerted by it on the pendulum counteracts the torque brought about by the center of gravity of the pendulum.
Claim 3
Dependent Claim
16 words
A level compensator as claimed in claim 1, wherein said light reflecting member is a mirror.
Claim 4
Dependent Claim
25 words
A level compensator as claimed in claim 1, wherein the center of gravity of the pendulum lies laterally above the support axis of the pendulum.
Claim 5
Dependent Claim
30 words
A level compensator as claimed in claim 1, wherein there is arranged on the pendulum an adjusting weight which is adjustable in relation to the support axis of the pendulum.
Claim 6
Dependent Claim
36 words
A level compensator as claimed in claim 1, further comprising a setting device arranged between one end of said spring and its point of application, the setting device acting in the longitudinal direction of the spring.
Claim 7
Dependent Claim
64 words
A level compensator as claimed in claim 1 further comprising a diaphragm situated on the pendulum and swingable jointly with the pendulum transversely to the projection light beam in a path near the microscale or the projecting apparatus in such a manner that it interrupts the light beam upon an impermissibly severe tilting of the balance about an axis parallel to the beam axis.
Claim 8
Dependent Claim
33 words
A level compensator as claimed in claim 6, wherein the diaphragm is designed as a diaphragm formed with a slot which extends in the longitudinal direction of the scale lines of the microscale.
Claim 9
Dependent Claim
28 words
A level compensator as claimed in claim 7, wherein the effective width of the slot is adjustable for adaptation to the permissible limit of error of the balance.
