Abstract: The invention relates to an optical communication bundle (10) comprising one layer (1), said layer (1) including at least three parallel optical fibers (2) which together define a first side of the layer (1) and a second side of the layer (1) opposite the first side, and a weft yarn (3) interlaced with the optical fibers (2) in order to maintain the optical fibers (2) relative to one another, said weft yarn (3) extending alternately on the first side and on the second side of the layer (1), passing through the layer (1) from the first side to the second side and from the second side to the first side. According to the invention, the layer (1) has a position in which it is wound about itself so as to form a bundle in which the optical fibers (2) are non coplanar; and the interlacing between the weft yarn (3) and the optical fibers (2) is adapted to allow the sheet (1) to pass from the wound position into an unwound position in which the optical fibers (2) are coplanar.

Abstract: The invention concerns a charging device for a hybrid or electric vehicle intended to be connected to an electricity distribution network (2) on the one hand, and to the terminals of the battery (10) of a hybrid or electric vehicle on the other hand, the device comprising two charging cables (61, 62) suitable for running, independently of each other, inside the vehicle, each being intended to be connected to a terminal of the battery, each charging cable (61, 62) comprising an electrical conductor (8) and at least one insulating layer (9) surrounding the electrical conductor (8), each charging cable further comprising a protective device (G) consisting of at least once sheath (G1, G2) disposed around the insulating layer and matching the assembly formed by the electrical conductor (8) and the actuating layer (9).

Abstract: A polymeric matrix including: 50 to 80%, preferably 64 to 73% PET; 18 to 50%, preferably 20 to 28% of a mixture of polyolefins; 0.1 to 15%, preferably 0.5 to 7% of at least one flame-retardant additive; 0 to 2%, preferably 0.2 to 1% of at least one antioxidant; 0 to 2% preferably 0.2 to 1% of at least one crosslinking promoter; 0 to 2%, preferably 0.2 to 1% of at least one anti-hydrolysis agent, the percentages being by weight of the total weight of the matrix. Also, the use of polymeric matrix in manufacturing electrical cables.

Abstract: The outer wall (19) of a heated room. In a variant, the air is heated by contact with the wall (19), which then is equipped with a Coanda effect air circulation (21). The air (24) is preheated before entering the room.

Abstract: A window of a double glazing system includes a window frame formed in a wall of a room, a sash fitted in the window frame and an outer glazing mounted in the sash, all of which are conventional. A second glazing is mounted to the sash and at an interior position relative to the outer glazing, so as to form an air circulation space between the second and outer glazings. The second glazing is heated by a transparent electrical resistance layer formed thereon and apertures are formed in the sash to create an air circulation path from the outside, through the air circulation space into the room. As a result, fresh air circulating into the room is heated by the heated second glazing.
