摘要:
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.
摘要:
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.

An apparatus for processing yarn in order to texturize and cut the yarn includes means for using a fluid to direct yarn into a tube which has a rotating spindle therein around which the yarn forms a wad. At least part of the fluid is exhausted from the tube and the wad is then cut and removed from the spindle.

The present invention relates to a socket for a busbar.A socket body is formed by folding a copper-aluminium portion in such a way as to form a sheath whose inside is formed by the copper-plated surface which serves for the fixing of the socket to an aluminium busbar by spot welding.The invention can advantageously be applied to power distribution busbars protected by sheaths.

An input card (7) is put in communication with apparatuses (16) the operation of which is to be monitored in order to initiate certain operations. A terminal-box (13) is interposed between the card (7), which possesses detector circuits (17), and the members (16).The two ends of each circuit (17) are associated with a respective inner terminal (12) of the terminal-box (13), and the two ends of each member (16) are associated with a respective outer terminal (14) of the terminal-box (13). Shunts (19,21) mounted in the terminal-box and connected to supply terminals (14a,14b) put one of the ends of each circuit (17) or member (16) at a common potential. The other terminal of each member (16) is connected to the other terminal of a circuit (17) by means of a connection (18).The invention is used to avoid the need for auxiliary terminal-boxes and cards with a common potential point.

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.
摘要:
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. C., for a period of time ranging from one minute to 150 minutes.Polyester yarn possessing a stable crimp and fiber prepared by cutting the said yarn, as well as the textile articles comprising this yarn are also disclosed.
