Abstract: Modular apparatus for coded interconnection between electronic cards and a printed circuit board, eliminates the risks of incorrect connection between a housing (9) containing a program card (8) and the bottom (1) of an auto-control container containing the printed circuit (4) and having rows of connections (6) for receiving male connections (7) arranged on one of the edges of the card (8) to connect them to the circuit (4). For each housing (9) and each row (6), the device comprises four rotary members (13, 16). The members (13) each carry a finger (17) which can engage in an orifice (18) in the members (16) when the angular positions between the members (13, 16) correspond to one another. The invention is used to make it easier to code the elements of a programmable auto-control.

Abstract: A container (1) for an auto-control possesses a bottom (2) carrying a printed circuit (3), to which connecting blocks (8) are fastened. The bottom (2) extends between two flank walls (34). The other two walls of the container (1) are latticed and consist of slides (11) intended for guiding the input/output cards towards the blocks (8). The bottom (2) also incorporates an inner wall (13) interposed between the circuit (3) and the interior of the container. The blocks (8) are laid against the periphery of apertures (14) and are accessible via these from the interior of the container (1). Each slide (11) carries a stud (31) engaged in a perforation (24) in one of the blocks (8). Adjacent the wall (13), the slides (11) have a certain play (J) between them. At their other end, they abut against one another. The invention is used to allow the slides to follow, for example, movements of thermal origin experienced by the circuit (3), without however fastening the slides to the latter.

Abstract: An electric distribution board serves for the distribution of two phases, or of two phases and an earth and has a back member which receives, according to choice, two mounts which are each appropriate to the respective method of current distribution, these mounts comprising selector means which only permit couplings with compatible current connector plugs.

Abstract: In this retractor, the central assembly 4 comprises a metal strip 9 and a covering 10. In the regions of the latter forming bearing surfaces for rotatively mounting the assembly 4, plates 25a, 25b are provided which are only covered with a thin layer of the covering on their periphery. In this way defects in the roundness of the central assembly and irregularities in the winding and unwinding of the strap are avoided.

Abstract: Pile textile elements are disclosed in which textile filamentary materials are assembled in a bundle, these materials being held together at one end only, by any suitable means such as adhesive or crepe paper wrapped around the bundle. The other ends of the filamentary textile materials of the bundle are not connected. The pile elements can be fixed to a backing such as a textile backing, furniture, bedding etc., in a conventional manner.

Abstract: A plurality of substantially parallel filamentary textile materials are assembled in a bundle to make a textile pile element. One end of the bundle has a base joining the materials at one end in a stable condition whereas the other end of the bundle contains strands which are free and open. The textile materials are retained in parallel arrangement by the base which is located in a mesh. The mesh is a support comprised of a planar structure having openings for receiving the bases of the elements. The mesh may be prefabricated or assembled during fabrication of the pile article. A pile textile article is made from the elements by a process of fabrication which includes the steps of inserting the textile elements in the opening in the mesh to result in an article which has application to furniture, clothing, toys, hats and decorative items.

Abstract: An electricity distribution column for administrative premises is made up of a U-shaped section whose top does not touch the ceiling and receives a tubular extension going up to the latter and receiving the connecting conductors, the ends of the branches of the U serving as a guide for a flexible cover inserted either from the top or the bottom.

Abstract: An openwork textile structure is formed from at least one textile web and has a plurality of regularly and/or randomly distributed open areas wherein each open area is separated from the adjacent open area by at least one compressed zone of textile materials contiguous with at least one zone of textile materials having a greater apparent diameter than the compressed zones, and wherein the textile materials of the web remain parallel to one another in the compressed zones. Three-dimensional openwork textile structures can be formed by superimposing two or more of the openwork textile webs and gathering together and compressing in parallel arrangement, textile materials from at least two adjacent superimposed webs.

Abstract: A process for the preparation of texturized multifilamentary polyester yarn possessing a stable crimp, in which the yarn passes first through a crimping device comprising an injector where the yarn is subjected to a stream of hot fluid which separates the filaments, and thereafter through a stacking nozzle to cause crimping, characterized in that the fluid is fed in at a temperature below the second order transition temperature of the polyester yarn, which feeding temperature is usually between 95.degree. and 220.degree. C., and in that the stack, after it issues from the nozzle is kept in the compressed state, subjected in this state to a high pressure of the order of 20 to 200 kg/cm.sup.2, and kept at ambient temperature or subjected to a heat treatment at a temperature below the second order transition temperature of the polyester yarn, which is usually at a temperature of up to about 220.degree.

Abstract: Apparatus for treating filamentary products, such as yarn, includes advancing the yarn in a groove, which has orifices opening in the bottom thereof, and which communicate with a channel through which a fluid is expelled. The channel lies in the wall of a cylindrical static body and is tangent to the inner wall of said body. The fluid supports the strand so that the yarn does not touch the groove. In addition, the fluid treats the yarn and helps to advance the yarn.
