Abstract: A motorized security locking system which is intended to be placed on the door of a high security enclosure and whose operation is reliable and more compact. The motorized security locking system includes: a case (1); a sliding bolt (3) movable in translation between an “in” position and an “out” position, and including a front end face (37), a back end face (39), two lateral faces (41), first (43) and second (45) longitudinal faces; and a controller (5) for controlling the movement of the sliding bolt, and including a motor (21), an actuator for actuating the motor, and a cam and a lever (25, 27), for connecting the motor to the sliding bolt, to transmit the drive force from the motor (21) to the sliding bolt (3) and to assure the movement thereof. The motor (21) is a motor with a single rotational direction.

Abstract: A drive device for locking a conditionally opening lock, including a motor means (MT) comprising a drive element (36) having an axis of rotation (X1), a transmission arm (26) mounted about an axis of rotation (X2) distinct from the axis (X1), a locking block (PVI) connected mechanically to the arm (26) and adapted to occupy an active position (P1), to oppose the displacement of a bar, and an inactive position (P2) allowing displacement thereof, and elastic means (48) for putting the locking block (PVI) under bias, when the block's displacement is impeded by the bar, wherein the elastic means (48) are arranged between the drive element (36) and the transmission arm (26), these elastic means (48) being in direct driving contact with a coupling surface (54) of the transmission arm (26).

Abstract: A device for lifting, in particular in the event of a breakdown or failure, the ban on the opening of a conditional opening locking system. This device includes: driving means (MT); a transmission member (28); and a blocking member (PVI) connected to the driving means (MT) by the transmission member (28) and able to be actuated by the driving means (MT) to occupy an active position (P1) in which the blocking member opposes the movement of a bar, and an inactive position (P2) in which the blocking member authorizes the movement thereof, the device including de-activation means (54, 64, 66) provided for freeing the transmission member (28) and authorizing the release of the blocking member (PVI) from the blocking member's active position (P1). The device is applicable in particular to a conditional opening locking system and particularly to a time lock.

Abstract: A contact sensor for very precise calipering of workpieces. The sensor has a force generating mechanism with two oppositely acting elastic members (64, 66) connected to one part (34) of the suspension device of a feeler (42) and deformable in the direction of movement of the feeler. An assembly carried by another part (36) of the suspension device includes an abutment (82), two mobile elements (72, 74) acting reciprocally on the two elastic members, and a spring (78) permanently biasing the mobile elements against the abutment from opposite directions. When the feeler is in a rest position, the two elastic members are pre-stressed by the mobile elements so that both elastic members remain under tension as long as movement of the feeler is confined to a calipering zone.
