Abstract: A data processing circuit includes a data processing unit including two signal-conversion circuits and controlled switches connected to inputs and outputs of the conversion circuits. The data processing unit further includes a binary signal inlet, a binary signal outlet, and a memory unit. The memory unit includes capacitors each storing a binary piece of data. The capacitors are connected to a memory bus via switches. The bus is connected to the processing unit. In response to control signals provided to the controlled switches, the data processing unit performs at least the following operations: writing a binary datum in a capacitor, reading from a capacitor a binary datum stored therein and applying the datum to an output, and logically combining binary data stored in at least two capacitors.

Abstract: A folding device including a folding member, and at least one first belt adapted to act in a forwarding plane on a product to be folded in order to position it opposite the folding member, the device including a movement device for moving the or each first belt relative to the forwarding plane between a first position, in which the first belt exerts a first pressure on the product to be folded, and a second position, in which the first belt exerts a second pressure on the product to be folded that is lower than the first pressure. The movement device is adapted to make the belt alternate between the first and second positions.

Abstract: A pyrotechnical firing installation comprises a plurality of detonators (3, 4), each with an electric cable (5, 6) comprising at least two connection conductors, and a surface line to which is connected the cable of the detonator. The surface line is formed by sections. Every section comprises a terminal or end part (5a, 6a) of the electric cable (5, 6) coming from a detonator (3, 4) and an end connector (7, 8) to electrically connect this terminal part (5a, 6a) to the cable of the next detonator, at a point of the latter defining the origin of its terminal part.

Abstract: Programmable pyrotechnical firing installation comprising a programming and firing control unit (8), a programming and control line comprising two conductor wires (6a, 6b) and a plurality of electronic detonators (4) mounted in parallel on this two-wire line, wherein the programming unit (8) comprises means (9, 10) for establishing a continuous voltage between the two wires (6a, 6b), means (9, 10) for producing pulses of this voltage so as to form coded signals, and means (11, 9) for reading the current variations existing on the two-wire line, wherein every detonator comprises an electronic module (12) that has means (14, 17) suitable for producing, in response to certain of the coded signals of the programming unit (8), current pulses in the two-wire line (6a, 6b) for forming coded signals.

Abstract: A mechanism for manoeuvring a door more particularly designed to be associated with a bar for avoiding panic. The mechanism comprises a pivoting bolt (26) provided with a slot wherewith it can co-operate with a lock-bolt keeper, a pivoting cam (35) for preventing the bolt from rotating towards a so-called loose escaping position and a member actuating (45) the cam to release the bolt.

Abstract: An electronic module for a detonator, the module comprising an electronic circuit (4, 5, 6) encapsulated in a mass of hardened resin (7) in which there terminates at least one inlet conductor (8) and from which there extend two outlet conductors forming a detonator ignitor line (9), the mass of resin (7) being received in a tubular housing (1) which extends beyond the mass of resin (7) adjacent to the ignitor line (9) to define a cavity (11), the outlet conductors of length greater than the depth of the cavity forming an ignitor line (9) short circuited outside the mass of resin inside the cavity (11), which cavity is provided with a removable end cap (12).
