The invention relates to an assembly including a tap for controlling fluid under pressure and a protective cap mounted around said tap, the tap including at least one handling member that includes a lever pivotably connected to the body of the tap and manually actuatable by an operator between at least a first rest position adjacent to the body of the tap and a second active position shifted by a nonzero angle relative to the body of the tap, the cap defining an inner protective space for the tap and being provided with at least one first side opening that enables movement of the lever between the first and second positions, the lever in the second position thereof intercepting the plane of the first opening and optionally projecting beyond the space of the cap, and characterized in that, in the mounted position for the use thereof, the cap is turning, that is, freely movable in rotation relative to the body of the tap around an axis, and in that the portion of the cap defining the first opening has contact edges capable of coming into contact with the lever when the latter intercepts the plane of the first opening and in that the cap is set into rotation relative to the tap, the contact edges being oriented according to predetermined angles to exert force on the lever urging the latter towards the first position thereof.

The present invention relates to a container packing structure, characterized in that it comprises a crystalline phase containing 55 to 97% by weight of xonotlite crystallites and 3 to 45% by weight of tobermorite crystallites. It also relates to a method for fabricating such a packing structure, and the container containing same, and its use for storing fluids such as gases.

The present invention relates to a packing structure for containers, characterized in that it comprises a material of xonotlite and/or tobermorite and/or foshagite crystal structure crystallized in the form of needles, at least 50% by volume of which have a length ranging from 2 to 10 &#x3bc;m and a thickness ranging from 0.2 to 1 &#x3bc;m. Process for manufacturing such a packing structure and gas container containing it.

The invention relates to an expansion valve block which is equipped with coordinated means () for isolating the high-pressure circuit () and the low-pressure circuit () such that, when the gas delivery inlet is opened and closed, the two circuits are automatically controlled using the sequence that best guarantees the immunity of the installation.

The invention relates to an oxy-fuel torch. The torch comprises a body ( ) comprising a number of pipes for conveying at least two streams of gas between inlets ( ) and outlets; at least two valves ( ) mounted in said body capable of adopting a closed rest position and an open active position; a single control ( ) for said valves and mounted so that it can move on the body and able to be moved so that it collaborates with said valves, capable of adopting a first stable position in which all the valves are at rest and at least one second stable position in which at least one of the valves is in the active position; controllable means ( ) of locking said control ( ) so as to secure it, at rest, to said body; and at least one controllable delivery adjusting means ( ) mounted on said body for adjusting the delivery of at least one of said streams of gas.

The tap/pressure regulator assembly, advantageously housed in a streamlined cowl forming a bottle-handling bonnet (C), comprises a body (1) intended to be mounted on a gas bottle and defining, on the inside, a gas utilization circuit, going to an outlet (3) via an isolating valve actuated by a lever (5) and via an adjustable pressure regulator (4, 25), and an independent filling circuit going from a filling fitting (6). The body (1) also carries high-pressure and low-pressure pressure gauges (8). Application especially to welding gases. FIG. 2 to be reproduced.
