Abstract
Abstract The vibration forces between a frame and a continuously oscillating mass are absorbed by making the oscillating mass system and its drive means equal and by fitting each such system and means to the frame with identical resilient elements such that oscillation movements of system and means occur out of phase one with the other to absorb the exciting vibration forces.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
90 words
In an arrangement for compensating oscillations of the mass forces of a driven oscillating spring-mass main system by means of a spring-mass auxiliary system operably guided in a continuation of the same movement path as said main system in a manner that it oscillates at the same frequency as, but out of phase with, said main system, in which said auxiliary system has the same natural frequency as said main system, the improvement comprising a differential lever system for coupling the two said systems to compensate for external spurious forces.
Claim 2
Dependent Claim
90 words

Claim 3
Dependent Claim
26 words
Apparatus as claimed in claim 1 wherein said differential lever system is coupled to the main system and to the auxiliary system by yieldable joining means.
Claim 4
Dependent Claim
14 words
Apparatus as claimed in claim 2 wherein said yieldable joining means comprises spring means.
Claim 5
Dependent Claim
15 words
Apparatus as claimed in claim 2 wherein said yieldable joining means comprises as fluid coupling.
Claim 6
Dependent Claim
14 words
Apparatus as claimed in claim 4 wherein said fluid coupling comprises a pneumatic dashpot.
Claim 7
Dependent Claim
14 words
Apparatus as claimed in claim 4 wherein said fluid coupling comprises a hydraulic coupling.
