摘要:
An oxidation chamber for use in the treatment of organically contaminated water and waste liquids includes a lamp seal assembly (36) that accomodates the thermal expansion of an ultraviolet lamp (42) while at the same time protecting the lamp (42) from direct contact with the liquid being treated. The lamp seal assembly (36) facilitates replacement of burned out lamps and cleaning of the protective tube (32) that surrounds the lamp (42). In another aspect of the invention, a specially designed family of baffles (28 and 30) and distributors (90, 92, and 94) are provided so that the chamber can accomodate a wide range of flow rates simply by replacing one set of distributors by a different set of distributors.
摘要:
II s'agit d'un luminaire comportant un socle (11) sur lequel un capot translucide (14), communément appelé verrine, est articulé par l'intermédiaire d'une bordure (26), qui est reliée au socle (11) par au moins une charnière (28), et dont il est solidaire, la charnière (28) comportant elle-même deux éléments de pivotement (30, 31) en prise à tourillonnement l'un avec l'autre, l'un solidaire du socle (11), l'autre solidaire de la bordure (26). Suivant l'invention, l'élément de pivotement (31) solidaire de la bordure (26) appartient à une patte élastiquement déformable (32), en sorte que, par déformation élastique de celle-ci, il peut être désolidarisé de l'élément de pivotement (30) solidaire du socle (11), et, donc, que le capot translucide (14) peut lui-même être désolidarisé de ce socle (11). Application, notamment, aux blocs autonomes d'éclairage de sécurité.

Le feu de balisage comprend un capot (12) encastrable dans le sol, dans lequel se loge une source lumineuse (22) et un couvercle (14) muni d'au moins une ouverture intégrant un bloc optique (18) en face de la source lumineuse. L'étanchéité du blc optique vis à vis du couvercle est assurée par un joint (20) dont la forme épouse sensiblement celle du pourtour (18c) d'une partie de base du bloc optique et qui est comprimé au moyen d'un organe presseur (26) appliqué contre une surface inférieure du bloc optique. Le couvercle (14) offre un logement prévu pour le joint défini par des surfaces de contact comprenant une paroi (14a) en regard du pourtour du bloc optique et une butée supérieure (14b) pour le joint (20) parallèle au plan moyen du couvercle.Le pourtour du bloc optique (18) est conformé pour agir sur le joint (20) à la manière d'un coin de sorte que le joint est comprimé contre les surfaces de contact (14a, 14b) sous l'action de l'organe presseur (26), le joint étant réalisé en un matériau susceptible de fluer sous une contrainte en compression afin de combler l'espace (24) entre le pourtour (18e) du bloc optique et la paroi en regard (14a).
摘要:
A lamp comprising a lamp housing (2) and a lamp glass (3) as well as internal, electric components has an insulating bowl (9) for receiving the internal electric components so that these are arranged water- and moisturetight. In a preferred embodiment, the bowl (9) has an open side which faces toward the lamp glass (3) so that the water- and moisturetight space is formed by the bowl (9), the lamp glass (3) and a sealing ring (18).
摘要:
The invention concerns a light ramp (1) comprising a base section (2) with two side wings and including at least: a transparent plastic section (3) in the longitudinal direction with two edges co-operating with the base section (2) side wings so as to completely cover them by enclosing them; and two aluminium covers (4) located at the ramp (1) ends so as to enclose the transparent section (3) and the base section (2) wing ends.
摘要:
A neon lamp assembly (10) includes a housing (16) having a cavity (14) with an aperture (20) for emission of light, a neon lamp (12) mounted within the cavity (14) in the housing (16) for emission of light through the aperture (20) and a lens (22) covering the aperture (20) in the housing (16). Connectors (24,26) are secured to opposite ends of the neon lamp (12). Each connector (24,26) includes a resilient boot (90) that is positioned in a recess (62) in the housing (16). The resilient boot (90) locates the lamp (12) in the housing (16) and cushions the lamp (12) against shock and vibration. The neon lamp assembly (10) further includes a light-transmissive, conductive mesh (34) covering the aperture (20) in the housing (16) for substantially blocking the emission of RF energy from the housing (16), and an electrical conductor (124) for coupling the conductive mesh to a reference potential, such as ground. The neon lamp assembly (10) is typically used as a stop light in a vehicle.
