Abstract: A heating device with a catalytic burner for a fuel gas is equipped with a member for regulating the thermal power. The regulating member includes a metal flap for regulating the flow of the mixture to be burned in the catalytic burner. This flap, for example a heat-sensitive bimetallic strip, can move between two positions, namely a first position in which the mixture to be burned is stored in the device or discharged in the manner of a leakage through an orifice in a wall of the heating device, and a second position which allows a maximum flow rate of the mixture to pass through the catalytic burner. The invention applies to all types of heating devices with a catalytic burner.

Abstract: The present invention relates to a hot air-generating device, combining a catalytic gas burner and a fan. According to the invention, on the one hand, the catalytic burner is of the induced-air type, for which means for mixing primary air in with the pressurized fuel gas are arranged upstream of the burner and, on the other hand, these same means comprise a component for drawing off oxidant air, independently of the circulation conduit which draws off primary air outside the latter. The invention can be applied to any kind of hot air-generating device, such as a hair drier and a hot-air gun for stripping paint.

Abstract: The present invention relates to a valve and container provided with such a valve, which can be used with portable apparatus using fuel gas, normally operating with piercable cartridges. The valve according to the invention is characterized by the presence of a concave surface on the top of the axial boss of the cup. The corresponding transverse seal assumes the same concave shape as the top of the boss.

Abstract: In a heating applicance with an induced-air catalytic burner, the catalytic burner comprises a refractory core having extending right through it axial conduits for the circulation of the combustible mixture, and dynamic braking means are provided in relation to the core, to make it possible to obtain at the outlet of the burner a speed profile making it possible to prime the ignition of the catalytic burner. A downstream flame heats the core until the catalytic burner is activated, at which moment the downstream flame disappears automatically.The invention applies to all types of heating applicance of the portable type, whatever their uses.

Abstract: Its casing (1) comprises two adjacent compartments, leakproof in respect of each other, namely a first compartment situated at the rear, in communication with primary or combustive air inlet ports (1a), in which the entry (7a) of the burner (7) is arranged, and a second compartment containing most of the melting duct (4) and the remainder of the burner (7), in communication with ports for the removal (1b) of the combustion fumes.

Abstract: The invention relates to a new complex filiform textile element comprising fibers of an inorganic material.The element in accordance with the invention is characterized by the fact that the fibers are contained on the outside by an enveloping but open structure of metal, the total area of the openings (So) being greater than the total area of the enveloping structure (Se) covering the apparent peripheral surface of all the entire fibers.

Abstract: A valve intended in particular for closing a container of fluid under pressure, more particularly gas in the liquid and/or gaseous phase, which comprises a seat, a movable sealing valve member mounted so as to bear elastically against the said seat, an elastic element forming a spring and having a fixed portion, and another movable portion supporting the said movable valve member, is characterized in that the elastic element is a spring having a shape permitting axial and radial retraction of the movable valve member in relation to the seat.

Abstract: A system of fastening an apparatus on a cartridge of fluid under pressure provided with a dispensing and/or filling valve and an annular bead surrounding the said valve, this fastening system, which comprises:a central core for fastening the said apparatus, comprising fluid dispensing means intended to cooperate with the valve of the said cartridge;a tubular sleeve surrounding the central core, movable axially relative to the latter, and provided with radial claws adapted to clip onto the bead of the cartridge;an annular stop serving as support against the bead of the cartridge;means of axially displacing the tubular sleeve, is characterized in that the annular stop is separate from the tubular sleeve and axially fixed relative to the central core and has an operative face against which the annular bead of the cartridge comes to bear when the said sleeve is displaced axially in the direction of the apparatus.

Abstract: A portable stove of the type fuelled from a replaceable pressurized combustible gas cartridge which is secured inside a cover member supporting a burner head and having means for connecting the burner head to the replaceable cartridge. A pair of covers, which telescopically fit one into the other have the dual function of serving separately as saucepans or in co-operation as an expandible housing for storing the stove, the covers being selectively telescopable to relatively greater or lesser extents, respectively to store the stove assembled or alternatively disassembled. The stove has arms which are shaped so as to provide, when the arms are extended, upstanding portions which are inscribed in a circle whose diameter is greater than the external diameters of the covers.

Abstract: A container for enclosing a portable stove either in a first fully assembled configuration having one height, or in a second partially dismantled configuration having a second lesser height, the container comprising two saucepans serving as covers and telescopable together to accomodate the stove having either said first or second height, the saucepans having two sets of selectable latch elements vertically spaced along their sidewalls to latch the saucepans at one of the selected heights, and the latch elements being supported on sidewalls which are so shaped that the saucepans can be telescoped together with the latch elements sliding freely between them without snagging on adjacent sidewalls.

Abstract: In a device for tapping gas from a gas-containing cartridge, there is provided a screw socket into which a threaded end of a tap forming part of a gas-using appliance is screwed, a piston spring-loaded in the direction of the end of the socket and bearing at its end sealing means engaging the cartridge, a perforating needle mounted on the socket and extending through the piston, and stop means to limit the travel of the piston under the action of its spring. The piston is hollow and of larger diameter than the socket which latter extends into a bore in the piston, the piston sliding over and outside the socket. By this means, the risk of seizure of the piston in prolonged use of the device is considerably reduced.

Abstract: A portable stove of the type fuelled from a replaceable pressurized combustible gas cartridge and having means for connecting a burner head to the replaceable cartridge, said stove being equipped with a dished wind shield having a rim which surrounds the burner head, and cooking vessel support arms pairs of which are formed by yokes pivoted along their middle sections on the floor of the dished wind shield such that the arms are movable between cooking vessel supporting positions in which the said arms extend beyond the rim of the said wind shield and stowing positions in which the said arms are moved back within the periphery of the rim. A pair of covers, which telescopically fit one into the other have the dual function of serving separately as saucepans and in co-operation as an expandible housing for the stove.
