Abstract: A light fitting is adjustable to vary the beam direction and for this purpose comprises a rotatable support stem carrying a lamp housing to permit rotation of the lamp housing about a pivot axis inclined at 45.degree. to the stem axis and to the central axis of the lamp housing. A handle fastened with the lamp housing and on the side of the stem remote therefrom can be manipulated to turn the lamp housing and stem around the stem axis to rotate the lamp housing about the pivot axis.

Abstract: Apparatus for distributing electic current, especially in a low voltage track lighting system includes: (i) a cable in the form of a rigid rod having coaxial conductors and male and female couplings at its opposite ends allowing the cable rod to be connected end-to-end with other similar cable rods, and the inner conductor having a spring loaded contact at one end; (ii) a coupling unit which may be used to connect rotatably one cable rod to another cable rod or an appliance, the unit having relatively rotatable housing parts defining respective male couplings at the opposite ends of the unit, and contacts arranged to project axially at the opposite ends, the contacts being connected by a flexible braided conductor and urged apart by a coil spring; and (iii) a coupling including a track with a channel having a connector carried by an inner wall and side walls with inturned flanges, a connector (which may be a cable rod or coupling unit) with a screw threaded end through which a contact projects, and a nut whic

Abstract: An electrical connector (cable rod) comprising coaxial conductors and coupling means at each end thereof to enable the cable rod to be connected releasably but securely end-to-end with another substantially identical cable rod to form a rigid cable rod assembly, with electrical continuity of the inner and outer conductors being maintained over the length of the assembly, the inner conductor including a contact portion at one end retractable against a spring force exerted thereon to ensure firm axial abutment with the inner conductor of another cable rod coupled to said one end.
