Abstract: A self-stripping electrical connector has a grounded bar formed with at least one threaded bore, a dielectric lower support part secured to the bar over the bore and formed with two adjacent outwardly open lower guide passages, a pair of electrically conductive and generally parallel lower tubes having lower ends formed with slots aligned with the respective lower passages and upper ends also formed with slots, and respective guides on the lower support part carrying the tubes for movement toward and away from the bar with the lower-end slots aligned with the respective lower passages. A dielectric upper support part overlies the lower part and is formed with two adjacent outwardly open upper guide passages aligned with the upper-end slots of the respective tubes.

Abstract: This programmer comprises programme-cams corresponding to a plurality of programmes having clearly separate starting points disposed at angular intervals from one another. It further comprises a control element adapted to be rotated manually for selecting the initial position of one of the programmes. This element comprises lateral pins adapted to engage corresponding orifices formed in a coaxial registering control cam. On the opposite side of this cam a disc rigid with the programme-cams is provided; this disc is rigid with the programme-cams but spaced therefrom. The disc comprises ramp means cooperating with bearing faces formed in the control cam. Spring means interconnect the disc and the control cam in diagonal directions.

Abstract: A connection device, in particular for telecommunication lines, comprises a casing consisting of two substantially identical parts, each comprising, on their open assembly side, a plurality of projecting parts and recessed parts in the form of castellations. The dimensions of the castellations are such that they are able to penetrate one in the other. A passage is contained in each projection of one part of the casing and in the corresponding recess in the other part of the casing. Each passage contains two conductor elements arranged in facing relationship. The elements have split end parts arranged on opposite sides of the casing, into which electrical connections can be made.

Abstract: A connection device includes a tubular connection member supported by an individual insulating support. The tubular connection member has a second end with dimensions so that it is able to receive the first end of another tubular connection member. A slot is formed in the second end and a slot is formed in the first end. The slots are adapted to receive a cable. The two tubular members are housed inside two half-sockets and an intermediate half-socket. The three half-sockets are housed in a common insulating case. The second tubular connection member may have a second slot formed in its second end which can grip another cable.

Abstract: The invention relates to a connecting element consisting of a plate whose faces operate on either side of at least one automatically stripping connecting plug, in conjunction with an electrical conductor, in order to ensure the connection of the latter into the said plug. The plate consists of two faces through which two passages are provided, of sufficient dimensions to allow the conductor to pass through. These passages have two opposite edges arranged in the direction in which the plate is pushed in. The first edge is directed towards the free ends of the faces, in order to work in conjunction with the conductor when the latter is connected. The second edge which is opposite is provided in order to ensure the disconnection of the said conductor out of the plug, when the plate is withdrawn in the direction 18. An element of this kind can be used especially for connecting and disconnecting wires of telecommunication lines, on distributors or subdistributors.

Abstract: A synchronous motor comprises a rotor of permanently magnetized high coercivity material and a stator formed of two metal plates having projecting imbricated poles which are placed between an induction coil and the rotor. The air gaps between the ends of the poles of one plate and the other plate are at most equal to one tenth the length of said poles and up to a maximum value of 1.2 mm, so as to increase the self-induction of the coil hence enabling a reduction of its resistance and a saving in the cost of the wire of the coil.

Abstract: A drive mechanism, for example of a blind with vertical slats, comprises first and second rotatable driving elements kinematically connected to a common rotary actuating element respectively by a first coupling arranged to immediately couple the first driving element for a limited rotation with the actuating element when the latter is rotated and a second coupling arranged to couple the second driving element for rotation with the actuating element after a given rotation of the latter. Each coupling comprises, on the first driving element and a facing fixed surface for the first coupling, and on the second driving element and the actuating element for the second coupling, a helix or spiral ramp and a facing transverse groove housing a ball which allows a limited relative rotation of the respective parts.
