A gain control device for a CRT video monitor in which the front face of the monitor corresponds to the screen of the tube and comprises various control buttons, among which is a gain control button. A gain control button circuit receiving the video signal in accordance with the invention is arranged at the neighborhood of the monitor rear face close to the tube socket. This circuit comprises an electronic potentiometer controlled by a d.c. signal set by a potentiometer arranged at the neighborhood of the front face and coupled with the gain control button.

A connection device is provided including a housing with a chimney for inserting wires to be connected, extended inside the housing, and in which a catch is locked. A plug, having a slotted clip for gripping, pulling and stripping the wires by extrusion of their sheath between the catch and the clip, is driven into the housing. The clip is locked on the housing. The space between the clip and the catch is less than the diameter of the core of the wires.

A leak monitoring and emergency venting apparatus for a double-walled tank includes a pipe for connecting a space between the walls of the tank to the atmosphere, a plug releasably closing an outer end of the pipe, and a pressure gauge in the plug in fluid communication with the interior of the pipe for monitoring the fluid pressure between the walls of the tank. If the pressure in the space between the walls of the tank rises above a predetermined level, the plug and gauge are discharged from the pipe allowing venting of the space to the atmosphere.

A pressurized fluid filling nozzle provided with a ring for fastening on an adaptor connected to a container and with a controlled valve adapted to selectively control flow of fluid through a conduit. A sensor detects the fastening of the nozzle on the adaptor and makes it possible to render a kinematic link between a control member and the valve active to displace the valve from a position where it obturates the conduit towards a position where it leaves a passage free for fluid flow. The control member is a trigger provided with at least one profiled guide which comprises two parts which cooperate with a guide element of a lever articulated on the valve. Depending on a position of the guide element, a transmission of force between the trigger and the valve is, or is not, possible.

A ski including an upper surface whose transverse section has a rounded convex shape over the greater portion of the length of the ski. The average radius of the upper surface varies in accordance with the considered longitudinal position of the transverse section along the ski, and is less in the central zone of the ski than in the vicinity of the front and rear end of the ski. This enables the height to be increased in the central portion of the ski and at the same time to reduce the height of the sides of the ski.
