Abstract: A fluid dispenser and applicator assembly comprising: a hollow reception body (1?) including a housing (22?); and a fluid dispenser (D?) including angular orientation means (16, 64) for bringing the fluid dispenser (D?) into a determined angular position relative to the reception body (1?); the assembly being characterized in that the angular orientation means (16, 64) cause the dispenser (D?) to turn as it is pushed into the reception body (1?), until it reaches its determined angular position.

Abstract: A fluid dispenser having a reservoir (1), a dispenser head (T) provided with a dispenser orifice (62), a dip tube (22), a pusher (6) axially movable over a determined stroke, an electric pump (4) that delivers air into the reservoir (1) so as to force the fluid through the dip tube (22) and actuated by the pusher (6), and a fluid outlet valve (7). All of the air coming from the electric pump is delivered into the reservoir. The electric pump (4) is activated by the pusher (6) as soon as it leaves its high rest position, and the outlet valve (7) is opened only in the proximity of the low depressed position, such that the electric pump (4) is electrically powered before the outlet valve (7) is opened and delivers air into the reservoir (1) with an increase in pressure that is less than 1 Bar.

Abstract: The invention relates to an installation for exposing a double-sided printed circuit card to light through artworks. The installation comprises a first artwork-support (10) that is fixed, a second artwork (14) that is movable, vertical displacement means (26, 28) for moving the second support, and mechanical connection means between the displacement means and the second support, the first and second supports having relative positioning members (12, 24) suitable for mutual co-operation when the two supports are in the working position.
