Abstract: This invention relates to an ordnance fuzing device in general and more picularly to a fluidically driven safety and arming mechanism. The present invention also utilizes a fluidically driven electrical generating means capable of transforming pressure energy of a certain magnitude into useable electric energy.The present device comprises an enclosed volume defining a resonant cavity having an annular column of fluid directed toward such cavity so as to produce oscillations therein. A rod connected to a diaphragm of the cavity senses the oscillations of the cavity and causes a mass located at the tip of the rod to undergo translational motion of an elliptical pattern and thereby to drive a cylindrical smooth gear which is disposed adjacent the mass, such that the elliptical motion of the mass rotates the gear. As an additional feature, the invention further provides for a flexible reed which is joined to the rod to transfer oscillations to a magnetic field so as to produce useable electrical energy.

Abstract: This invention concerns an oscillator for time measurement, comprising a resonator the oscillation of which is maintained by at least one part reciprocated by electrostatic forces relative to at least one electrode connected to a direct voltage source, said part being periodically charged by contact with the electrode, or electrodes comprising an elastically deformable contact making member whose elastic deformation energy is much less when in contact with an electrode than the motional energy of the resonator.
