Abstract: A geophone spring system for suspending a reference mass which comprises first means (2,3,5) for centering the reference mass both laterally and along its axis and second means (4,7i for centering the reference mass laterally and for providing a heavily damped compliance in a radial direction to prevent the first means (2,3,5) from being stressed beyond its elastic limits.

Abstract: 57 A spring for use in geophones to suspend coils within a magnetic field assembly. The spring is formed from a disc and comprises an outer ring, an inner ring and three legs connecting the outer and inner rings, which legs are formed by removing portions of the disc in a predetermined pattern. The inner edge of each leg (7) lies on an arc having a radius at least 1.25 times greater than the distance from the center (9) of the spring (4) to the inner edge of the leg (7) at the point (11) where the leg joins the inner ring (6). Preferably each leg (7) is wider at its ends (10, 11) than it is in its middle (12).
