Abstract

1,152,369. Electromagnetic relays. LA TELEMECCANICA ELETTRICA Ing. AMATI & GREGORINI S.p.A. 7 June, 1966 [7 June, 1965], No. 25398/66. Heading H1N. Each set of contacts of a relay is controlled by an individual pneumatic time delay. As shown, cranked levers 3, 4 are normally in engagement with spring biased armature 1b and with respective plungers 9, 10 of pneumatic time delay units 11. On energization armature 1b is raised moving plungers 9, 10 against springs 13, 14. Contact sets (18) are actuated by each plunger through respective pivoted members (15, 16) (Fig. 2, not shown). The actuation of the contact sets on de-energization is delayed by the pneumatic devices 11, which have separate adjusting screws 12.
