Title
(EN) ANTI-DAMPING APPARATUS FOR KEEPING A PENDULUM OSCILLATION PERIOD CONSTANT.
(FR) APPAREIL ANTI-AMORTISSEMENT DESTINÉ À MAINTENIR UNE PÉRIODE D'OSCILLATION DE PENDULE CONSTANTE
Abstract
(EN)
A pendulum (1) comprises a cord (2) to which a permanent magnet pendulum weight (3) is attached and at least one anti-damping apparatus (8) comprising a second (6) and a third (9) permanent magnet weights which are mounted on a rod constrained to oscillate rotatively about a pivot (47) by a spring. Magnetic attraction occurs between the second weight (6) and the pendulum weight (3) in a standing end stop positions of the pendulum weight while the spring is maximally stretched, followed by relaxation of the spring and a phase of magnetic repulsion between the third weight (9) and the pendulum weight (3) during the downward phase of the pendulum weight.
(FR)
L'invention concerne un pendule (1) comprenant un cordon (2) auquel est fixée une masselotte (3) à aimant permanent et au moins un appareil anti-amortissement (8) comprenant des deuxième (6) et troisième (9) poids à aimant permanent qui sont montés sur une tige contrainte à osciller en rotation autour d'un pivot (47) par un ressort. Une attraction magnétique se produit entre le deuxième poids (6) et la masselotte (3) dans une position verticale de fin de butée d'extrémité de la masselotte tandis que le ressort est étiré au maximum, avant le relâchement du ressort et une phase de répulsion magnétique entre le troisième poids (9) et la masselotte (3) durant la phase vers le bas de la masselotte.
