An emergency lighting system, providing for stopping voltage over an electroluminescent filament upon a break in such electroluminescent filament.

Abstract: An electroluminescent lighting filament having a connector at a end thereof that may be removably connected to a connector at an end of a second electroluminescent lighting filament so that such electroluminescent lighting filament may be connected to another electroluminescent lighting filament. A storage spool upon which such electroluminescent lighting filament may be stored and unwound.

Abstract: A novel device is presented having at least one electroluminescent element and a casing to house at least a portion of the electroluminescent element, allowing at least part of the electroluminescent element to be extracted from the casing and at least part of the electroluminescent element to be retracted into the casing.

Abstract: An ink composition for use in a dielectric or electroluminescent (EL) layer of an EL device, as well as a method of preparation of such composition, are presented. The composition comprises a water-based dispersion of a hydrophobic polymer with a high dielectric constant, rheological additives and a dielectric powder or EL phosphor powder.

Abstract: A system for dry separation of powders into at least two fractions including a powder to be separated and a separator including a hollow body rotating about an axis and defining a cavity having a powder engaging surface, the surface of the cavity being a surface of revolution which rotates about the axis, an upper edge of the cavity having a greater diameter than a lower edge, a system controlling the rotation of the body, at least one feeder continuously feeding dry powder into a feeding zone adjacent to the cavity surface near the lower edge, the length of the feeding zone being at least an order of magnitude less than a circumference of the cavity surface of the lower edge, at least one discharge device continuously discharging the powder from the cavity surface, the at least one discharge device including a body arranged along substantially the entire length of the generatrix of the cavity surface and located immediately in front of the feeding zone aligned with the rotation of the cavity surface, a first

Abstract: A substantially flexible, electro-luminescent light source is presented. The light source comprises an electrodes' assembly, dielectric and electro-luminescent layers, and at least one outer, substantially flexible layer formed of insulating transparent material. The light source is provided with a heating element, and a power supply unit coupled to the electrodes' assembly and to the heating element. The power supply unit selectively operates the electrodes' assembly and the heating element, such as to heat the vicinity of the electrodes' assembly thereby maintaining desired temperature conditions in the vicinity of the light source and thereinside.

Abstract: An illumination system for illuminating an underwater space is presented. The system comprises an elongated flexible electroluminescent light source located substantially inside the underwater space and a power supply unit located outside the underwater space. The power supply unit is connected to one end of the electroluminescent light source. At least this one end of the light source, which is connected to the power supply unit, is located outside the underwater space. The light source has at least one light-emitting element located inside an inner insulating sheath, and has an outer insulating sheaf. The inner insulating sheath and the outer insulating sheath are separated by a continuous air gap coupled to an air region outside the underwater space. This prevents the light source from being affected by water, and thereby from the reduction of its lifetime.
