The head of the wick is made of a strip of asbestos sheet wound spirally round a metallic tubular seat, so as to form a small cylinder, to the base, of which is made fast by sewing or other¬ wise an ordinary cylindrical cotton wick. The active body or the vaporiser of my lamp may be made from any refractory porous material, capable to be moulded or stamped, such as kaolin, magnesia, asbestos or similar and impregnated by a solution of platinum chloride in con¬ junction with nitrates or chlorides of the refractory metals, such as thorium, yttrium, didymium or similar.

Improvements in the Production of Slow Combustion Lamps for Disinfecting, Therapeutic, and other purposes, 25 E Adolph Roubleff, of 3, rue de PAmiral Moucher, Paris, France, Civil Engineer, do hereby declare the nature of this invention and in what msnner the same is to be performed, to be particularly described and ascertained in and by the following statement: — My invention concerns the so-called “ lamp without a flame ” It is well 30 known that platinum or finely divided platinum (sponge or black), owing to its occluding properties, is able to convert any of the alcoholic vapours into their aldehydes, by substituting 2 equiv. oxygen for 2-equiv. hydrogen. This property has been utilised for many practical purposes, but chiefly as a means to produce formaldehyde from ordinary wood spirit (methylic alcohol) for disin- T5 feeling purposes. There are different systems of slow-combustion lamps now in use, but non of them—to my knowledge—are devoid of inconveniences and defects, which render [Price 8d.~\
