Abstract: The invention relates to a solder sleeve comprising a split sleeve of solder material having end surfaces of which take the form of form-fitting coupling elements, and to a method for forming such a solder sleeve, comprising of: i) providing a strip of solder material having end surfaces of which take the form of form-fitting coupling elements; and ii) bending the strip to form a sleeve, wherein the coupling elements mutually engage for coupling.

Abstract: A pot burner has a circularly cylindrical combustion space 10 with openings 60, 62, 64 in its wall for the supply of combustion air and with an inlet in its floor 32 for the liquid fuel. Concentrically in the combustion space 10 there is placed a first cage 28 with a smaller diameter and a second cage 42 with a larger diameter than the circular outlet 18 for the combustion gases. The first cage is shut off at the top by an upper cover wall 26 whereas the second cage 42 is shut off at the top by an annular outer part of the cover wall at a lower level. The second cage 42 is divided into an upper annular chamber 36 and a lower annular chamber 38 by a perforated ring 46. The floor 14 forming the bottom of the combustion space 10 is covered over by a shield 82 to prevent the floor 14 from being cooled by incoming cold air for combustion.

Abstract: A stove for combusting both liquid and solid fuels, said stove comprising: a burner area in which the burner for liquid fuel is located, a collecting area for combustion gas above said burner area and connected therewith; a discharge conduit for the combustion gas connected to the horizontal upper wall of that collecting area; and a combustion area for solid fuel provided in said collecting area and extending itself over the full length of this area and consisting of a lower V-shaped plate, two vertically extending side plates and a horizontally extending upper plate, all these plates being positioned at some distance of the corresponding walls of said collecting area, openings being provided in the upper part of the side walls of said combustion area for allowing the combustion gas of the solid fuel to evade towards the discharge conduit.

Abstract: A pot burner, which in an undefined sloping position with rocking movements functions well, particularly in vehicles and vessels, because the vaporing surface of the fuel is defined and because the vapored fuel is well mixed with air in a first cage, which is enclosed by a second cage.

Abstract: A burner comprising a substantially diamond-shaped housing with in the interior one or more partitions defining with the two housing walls opposite the burner mouth two or more similarly diamond-shaped burners, the partition most remote from the burner mouth having a flame opening the rim of which being bent away from the burner mouth, the burner mouth being so large that air flows entering through air supply orifices near said mouth reach to the middle or slightly beyond thereof and the bottom being recessed over some degrees in the center between the end walls of the burner.

Abstract: A gas burner with a nest of ribbons, the ribbons of which in at least one of the edge portions are provided with spacing means, said ribbons being collected such that in the nest of strips or ribbons one or more rows of gap-like main gas burner ports are formed between successive spacing means in which of the spacing means defining the main gas burner ports in the composite gas burner the spacing means facing the gas supply side are shifted by half a pitch relative to the spacing means facing the flame side.
