Abstract: The invention concerns methods and devices for bending a cylindrical tube or the like (1) so as to obtain two consecutive sections (2, 3) of said tube forming between them a non-null angle alpha. The method is essentially characterised in that it consists in producing, in the wall (4) of the tube (1), a wave (20) defined between two flanks (22, 23) forming between them a non-null angle beta substantially centred on the separation plane (21) between the two sections, then in producing a permanent plastic deformation of the wave (20) until the value of the angle between the two sections (2, 3) is obtained. The device enables to implement said method. The invention is useful in particular but not exclusively, for producing pipes for transporting fluids in motor vehicles or the like.

Abstract: Disclosed is a tubular housing having a threaded-base lamp bulb at one end and a "penlite" battery within the housing with its positive terminal stud separated from the bulb's positive terminal by a helical compression spring. The spring coils receive the lamp base and the spring is bottomed and centered in an annular retainer disc encircling the positive terminal stud of the battery. A conductive strap engages the endmost coil of the spring and extends the length of the battery to its base providing electrical continuity from the battery negative terminal to the bulbs threaded base. A push button, accessible at the end of the housing, moves the battery so that its positive terminal engages the positive terminal of the bulb.
