Abstract: A low voltage strip lighting assembly has an elongated flexible insulator strip having a base including two sides and a top surface having elongated slits that retain flat electrical conductors. A miniature wire terminal lamp bulbs are adjacent to the top surface of the insulator strip with terminals extending from the top surface of the insulator strip into a slit in the insulator strip to electrically contact one side surface of a respective flat conductor at any point along the length of the insulator strip, whereby the application of electrical power from an external source to each of the respective conductors will light the bulbs. A generally U-shaped lens covers the light bulbs and has legs engaging the sides of the insulator and inwardly-biased and secured to the insulator by the engagement of ribs into matching grooves in the insulator.

Abstract: An adjustable neck is provided for adjusting a lamp, in particular a lamp plugged onto a low-voltage rail, in as many alternative directions as possible. The adjustable neck is mounted between a clamping socket of the lamp and the replaceable incandescent body or bulb. The adjustable neck includes several joint members, each consisting of a ball portion that can be plugged into a corresponding joint seat portion of a next adjacent joint member and held there by a friction fit. The incendescent body can be surrounded by a lamp shade provided with ventilating slots. The clamping socket is embodied such that a positive anchoring is achievable even in the case of larger, heavier lamps.

Abstract: Conductor strip (1) for electrical and telecommunication conductors with one or several through metallic conductors (9), which are arranged to be connected up at any selected position, and which are arranged on or in an electrically non-conductive strip base (5). The metallic conductor or conductors (9) is or are embedded in a through electrically conductive string or cord (8) of plastic material. Because of the inherent resiliency of the material and/or the springiness of the strip structure, the conductor strip (1) is automatically lockable by expansion or outward springing of the strip, whereat the free ends of the strip (1) are caused to engage behind projections (4) of an installation channel (3).

Abstract: An improved space-saving and clearly arranged adapter apparatus for mechanical and electrical connection of installation devices such as automatic circuit breakers, motor protection switches, contactors, protectors, relays, and the like with bus rails of a bus bar system. The apparatus has an adapter housing which can be placed on the bus rails, contact bars in the housing, and adjustable clamps for mechanically and electrically connecting the contact bars to the bus rails. The contact bars extend to a connector side of the adapter housing and there form connectors for leads. The adapter housing has on its front a mounting bracket for mounting of installation devices.

Abstract: An illumination/ventilation system is described wherein the light tube used to support one or more incandescent lamps forms part of the ventilation system itself. The system includes a blower having a forced air outlet with first a conduit connectings the outlet of the blower to an inlet of the light tube. A second conduit connects to an outlet of the light tube to form a circulating air path through which air is forced by the blower to ventilate the light tube. Preferably, the light tube comprises an elongate base member and an elongate light diffuser for supporting the lamps along the light tube. The light tube also includes an elongate track member having a tongue along its entire length which mates which a groove along the length of the base member to secure the track in the base member. Each of the individual lamps is supported in the elongate track member by an adapter track clip which is press-fitted, rather than twisted, into the track.

Abstract: A low voltage lighting assembly which comprises a lamp holder, a pair of rigid electrically conductive arms, each arm having a lower end that passes through opposingly disposed apertures in the lamp holder in a manner so as to maintain electrical contact with a lamp socket disposed within the lamp holder, while said lamp holder is pivotable about the axis of the lower arms, each arm having an upper end with means to permit independent movement of an arm along one of a pair of spaced apart elongate electrical conductors and to be fixed in place to form electrical contact therewith. The conductors have means to connect to a suitable source of electric current, at a voltage of no more than about 24V. By pivoting the lamp holder about the axis of the lower arm ends, and moving each of the upper arm ends along the conductors, a lamp mounted in the holder may be positioned transversely with respect to the axis lying through the lower ends and longitudinally with respect to the conductors.

Abstract: A lighting track system for mounting to a vertical wall includes an elongated channel in the form of an inverted U with a horizontal web having an upper surface and connecting two depending legs, the channel retaining one or more electrical conductors extending therethrough, insulated from each other and the channel, and accessable for electrical connection from the open side of the channel. At least one of the vertical legs of the channel has an upstanding or depending flange that is provided with screws for attachment of the track to a vertical wall. An external source of power is connected to the electrical conductors, and one or more lighting fixture connectors mechanically attach and electrically connect to the track at any point along its length. In a preferred embodiment the track has a depending flange that terminates in an upturned lip for the support of suspended objects, such as paintings, wall hangings and drapes.

Abstract: The device comprises a rail (2) inside which two insulating support elements (10) are longitudinally disposed. Said support elements (10) are provided with projecting portions (10a) housing respective wires (11) provided with mutually facing contact surfaces (11a). The latter slightly project with respect to the projecting portions (10a) so that they can come into contact with contact elements (16) extending from a connection shank (13) and substantially flush therewith. The connection shank (13) is part of an adaptor (3) to which a safety low-tension-operated utilization unit can be connected and is engageable with rail (2) through a longitudinal opening (4a).

Abstract: A distribution bus 12 comprises a conductor sheet 16 and another electrode 18 separated by an insulating sheet 20 of foamed plastic or foamed glass, or by air.A jack plug 14 can be plugged in anywhere on the bus 12 by poking a contact pin 44 through a hole 64 in the conductor sheet 16 to contact the other electrode 18, and poking a contact sleeve 46 through the same hole 64 to contact the conductor sheet 16. The jack plug 14 is clipped to the bus 12 by clips 62 which are pushed through other holes 64 in conductor sheet 16 and are cammed by a rotatable wheel 28 into operative position.

Abstract: An improved housing for a busway system is provided by a two-piece ground bus which includes a generally U-shaped upper section having a top portion and a pair of parallel side flanges extending a predetermined distance and a generally U-shaped lower section having a bottom portion and a pair of parallel side flanges extending intermediate and parallel to the side flanges of the upper section. The main bus bars are retained intermediate the top portion and the bottom portion of the ground bus while also being positioned between the side flanges of the upper section of the ground bus. A side rail is provided on each side of the ground bus. A plurality of fasteners extend along the length of the busway section and connect each side rail with both the upper and lower sections of the ground bus.
