Title (EN) A TWO POSITION MECHANISM
(FR) MECANISME A DEUX POSITIONS
Abstract: front page image
(EN)Mechanisms in which one member may occupy one of two fixed positions and can be caused to change over from one position to the other at will. In order to accomplish rapid change-over with minimum energy input and minimum impact, an elastic suspension of this member is provided and so arranged that the change-over process is substantially a half cycle of oscillation in which the moving members starts and ends with no or little speed of motion. The moving member is captured in the vicinity of, and held at the fixed positions, against the force exerted by the said elastic suspension by mechanisms exerting short range forces upon it. When a change-over is to be initiated, the corresponding short range force is temporarily removed by an appropriate means. This then releases the said moving member, which executes substantially a half cycle of oscillation and is captured again at the opposite fixed position.
(FR)Mecanismes ou un organe peut occuper l"une des deux positions fixes et peut changer d"une position a l"autre a volonte. De maniere a effectuer un changement rapide avec un minimum d"energie et un impact minimum, une suspension elastique de cet organe est prevue et est concue pour que le procede changement consiste sensiblement en un demi-cycle d"oscillation dans lequel l"organe mobile commence et termine sans ou peu de vitesse de deplacement. L"organe mobile est saisi au voisinage des positions fixes et il est maintenu dans ces positions, contre la force exercee par la suspension elastique par des mecanismes exercant des forces de faible portee sur cette derniere. Lorsqu"un changement doit etre initie, la force de faible portee correspondante est temporairement degagee par des moyens appropries. Ceci libere alors l"organe mobile qui execute sensiblement un demi-cycle d"oscillation et est saisi de nouveau a la position fixe opposee.
