Abstract
Abstract This invention is directed to an arrangement for compensating and absorbing vibratory oscillations of a driven spring-mass system by means of an auxiliary spring mass system. The drive for a main spring-mass system is designed such that it is guided along the same axis as the main system and oscillates out of phase with the main system.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
In an arrangement for compensating oscillations of the mass forces of a driven oscillating spring-mass main system of a spring-mass auxiliary system, wherein the mass and spring rate of said auxiliary system are identical to the mass and spring rate of said main system, a magnetic means for coupling said systems, with said auxiliary system being operable by said magnetic means in a continuation of the same path of movement of said main system and oscillatable at the same frequency but out of phase with respect to said main system.
Claim 2
Dependent Claim
90 words
In an arrangement for compensating oscillations of the mass forces of a driven oscillating spring-mass main system of a spring-mass auxiliary system, wherein the mass and spring rate of said auxiliary system are identical to the mass and spring rate of said main system, a magnetic means for coupling said systems, with said auxiliary system being operable by said magnetic means in a continuation of the same path of movement of said main system and oscillatable at the same frequency but out of phase with respect to said main system.
Claim 3
Dependent Claim
31 words
The apparatus according to claim 1 in which said magnetic means comprises an electrically operated coil on a carrier in said auxiliary system and a magnetic element in said main system.
Claim 4
Dependent Claim
54 words
The apparatus according to claim 1 in which an identical spring means is remotely situated from said magnetic means in the path of movement of both said systems and connects each said system to a common surface, thereby making the forces transferred to said surface of the same magnitude and opposed to each other.
Claim 5
Dependent Claim
26 words
The apparatus according to claim 1 in which said auxiliary system and said main system include means for guiding both said systems along a common surface.
Claim 6
Dependent Claim
13 words
The apparatus according to claim 4 in which said guiding means includes rollers.
Claim 7
Dependent Claim
18 words
The apparatus according to claim 1 in which said main system comprises lenses located in an optical instrument.
Claim 8
Dependent Claim
13 words
Apparatus as claimed in claim 1 wherein said magnetic element is an electromagnet.
Claim 9
Dependent Claim
14 words
Apparatus as claimed in claim 1 wherein said magnetic element is a permanent magnet.
