To all whom t may concern.- l
Be it known that I, SILvIoTEoDoRo Tam, doctor of medicine, a ,citizen of Argentina, and a resident of No. 745 Calle Tucuman, in the city of Buenos Ayres, Argentina, have invented a new and useful Improvement in Abinfluence of the surrounding temperature, the.
work being at the timedonel by the different individuals and depends as Well onthe amount of liquids drunk. It has been demonstrated that sweat is of acid reaction. At the commencement of the'sudorific secretion the reaction is' more acid on account of the presence' of a greater amount of lactic acid and volatile The elements ordinarily found in the sweat are: water, small quantities of grease, urea, Cholesterin, lactic acid, nitrogenous acids, alkaline sulfates and phosphates, terreous phosphates, and iron oxid, some volatile acids-such asacetic, formic, butyric acid, @cc-free carbonio acid, and, according to some other authors, an albuminoidalbody and sudoric acid. These several elements vary slightly in accordance with the increased or lessened function of the sudoric glands.
Notwithstanding, the fixed elements diminish to ya considerable extent as soon as the secretion becomes very abundant, particularly if the sweat comes from the arm-holes or from the feet. In these parts the sodoriiic secretion contains abundant fixed residues when it is normal and incloses odorous bodies (acids, fats, amines, sulfurous bodies;) but when the sweat is very abundapt these elements diminish. In women the sweat of the armholes is more abundant and contains more odorous elements than in men. On the other hand, inthe latter the same features occur as regards the sweat of the feet. In both cases the sweat has for resultsagreat inconvenience for the clothes, which get wet, discolored, and
give ofi' a bad smell, whichrcannot .be taken l away-or corrected by any perfumes which may be employed -to that end. Neither by personal hygiene, the frequent change oi. the underclothes` stockings, dac., may the bad smell be.
suppressed when the upper-"clothes, dresses, trimmings, shoes, &c., have o'nce become 1mpregnated with the sweat, for these last-men-4 tioned clothings may generally not be washed.
have now succeeded 4in avoiding precisely these nuisances as regards the spoiling of the clothes and the bad smell' thereof by makingl dress-shields and insoles provided with a compound which I have discovered and which absorbs, neutralizes and deodorizes the sweat. I have. discovered said compound after numerous experiments, departing from the scientic principle of the acid reaction of sweat and ofzthe existence-therein of volatile odory 'ous acids. The `said compound consists of the mixture of several substances which' have sweat absorbing, neutralizing, deodorizing, and disinfecting properties. The formula of said Acompound is, by weight, parts: wood-charcoal, ((1,) four hundred parts; calcined magnesium'. or magnesium oxid, (MgO,) four hun? dred parts; slaked lime or calcium hydrate, Ca(HO)2, one hundred parts; zincoxid, (ZnO,) one hundred parts. The mixture of these bodies constitutes a powder the color of which varies from a grayish blue to black in relation to the predomination of one or the other vofthe ingredients, for the above formula is not absolute. Its absorbing power is most considerable and so are 'its deodorizing and .disinfecting properties, as may be' seen by the action of each-of these su'bstances. The Woodcharcoal, which may be suhstitu ted by washedanimal charcoal, absorbs the gases and condenses them within its pores. The oxygen on the surface escapes easily in of oxidizable organic matters which occur in a gaseous state, (volatile products ofthe sweat.) The charcoal also assists in absorbing'and retaining the sweatwhilehe other elements are developing their action. Itis at the same time a deodorizing and disinfecting agent, and although charcoal in general `reunites both properties in the highest degree when in a dry state the moisture as long as it does not attain the degree ofvlsaturartiorf does not prevent it from exerting said properties. T he calcined magnesium or magnesium oxid, which may be remplaced by carbonate of magnesium, (MgCOah, is little soluble in sweat. In the moist mediumproduced-by the sweat the the presencethe former and withthe carbonio acid, therethe product or compound 6V is located, and 4 Aated between the 'fabrics 7 and 8 without the addition of glue or other adhesive magnesium oxid combines with the water of matter.
The shape of the insoles and dress-shields .represented in the drawings may of course be varied without departing from the spirit of my invention, which embraces the application of the above-described compound, either axing or 2;h;xin,f the same to one or both sides of a fabric or tissue or placing it between two sheets or fabrics, stitched or sewed is any direction or manner desired, with or without the aggregation of an adhesive material, such as tragacanth or Arabic gum, or any other similar substance.
Having thus clearly described and ascer tained the nature of my said invention and in what manner the same is to be performed, I .declare that what I claim Visi-- ll. An absorbent and deodorizer consisting 4 ofa suitable material having applied thereto 'a composition consisting of charcoal, calcined magnesium, hydrate of lime'and oxid of Zinc. 2. An absorbent and deodorizer consisting of layers of textile material having an interposed layer of charcoal, calcined magnesium, hydrate of lime and oxid of zinc.
3. An absorbent and deodorizer consisting of layers of textile material, having interposed a layer of rubber and a layer of a composition containing charcoal, calcined magnesium, hymatter, or with such addition, in order to fadrate of lime and voxid of zinc.

by lforming a hydrocarbonate of magnesium, and thus neutralizing the acidity of the sweat. The calcium hydrate acts slowly by its alkalinity, audits disinfecting qualities also prevent the decomposition of the constituents of the sweat. The zinc oxid is an absorbing agent, and at the same time it renders the mixture more homogeneous. p
My said compound is used industrially in connection with the manufacture of dressshields and insoles for shoes and boots in the manner shown in the accompanying drawings, wherein# f Figure 1 shows a dress-shield.
