Abstract: An earthquake tremor responsive valve closing assembly that includes a magnetically suspended pendulous weight adapted to be dropped upon a cocked trigger assembly for an internally spring biased gas line valve in response to a decrease in magnetic retention force resulting from tremor induced displacements.

Abstract: A differential speed reducer has a wobble member mounted on an input shaft so as to follow a sinusoidal path of movement. A first gear journaled on the wobble member has a radially disposed cam surface on one face to follow the sinusoidal movement of the wobble member, and a second gear is axially spaced from the first gear with correspondingly formed cam surfaces aligned with those of the first gear, and a plurality of balls are interpositioned between the first and second cam surfaces to transmit torque from the rotary input shaft to the second cam surface. For multiple speed reduction, a second set of cam surfaces corresponding to the first cam surfaces is interposed between the input shaft and first set of cam surfaces, and rolling elements again impart torque from the input side into the first set of cam surfaces. The first and second sets of cam surfaces can be formed on different radii and concentrically positioned with respect to one another so as to form a very compact speed reducer unit.
