Abstract
1297267 Watches CENTRE ELECTRONIQUE HORLOGER S A 19 Dec 1969 [13 Jan 1969] 62015/69 Heading G3T [Also in Division H1] A flexion vibrator for regulating a timepiece has at least two vibration node axes and is mounted at these axes on rectangular section strips which are secured at a support at their other ends. In the embodiment shown, a crystal 1 may be vibrated Piezo-electrically, or by a magnetostrictive arrangement, along the indicated X-axis. The crystal is mounted on two strips 2, 3 by feet 4, 5, and may be similarly mounted on its opposite face. The strips are bent to provide torsion segments 6, 7 and loops 10, 11 to allow for changes in the distance between node axes during operation. The mounting arrangement is said to be sufficiently stiff to prevent the crystal striking other objects in a confined space, while withdrawing very little energy from the crystal in order that its motion should be as regular as possible. The mounting strips may be of copper-beryllium bronze, and the whole arrangement may be situated in a sealed housing, Figs.2 and 3 (not shown), in a watch.
