I det svenska, patentet 99621 beskrives ett forfarande och en anordning for elektrolytisk sondethelning av ,saltlOsningar enligt amalgamforfarandet med vertikalt anordnade katoder, vid vilket kvicksilvret, flytande Over en braddavloppskant, i tunt skikt ledes Over ett metallunderlag, corn har en slat yta och vars form är an.passad efter den form, som det nedflytande kvicksilverskiktet vid fritt fall antager under inflytande av ytsphnningen och fallaccelerationen under 1Ansyntagande till friktionen mot underlaget. Foretradesvis gores metallunderlaget vOl vatbart for kvicksilver fore elektrolytens igangshttande genom preparering, t. ex. genom overdragning med kvieksilverlosliga metaller. Swedish patent 99621 describes a method and a device for electrolytic probe tilting of, saline solutions according to the amalgam method with vertically arranged cathodes, in which the mercury, liquid over a brad drain edge, in a thin layer is passed over a metal substrate, corn has a smooth surface and whose shape is adapted to the shape which the descending mercury layer in free fall assumes under the influence of the surface surface and the fall acceleration during taking into account the friction against the substrate. Preferably, the metal substrate is made susceptible to mercury prior to electrolyte activation by preparation, e.g. by coating with mercury-soluble metals.

Genom anvhndning av endet beskrivna shttet utbildad anordning undvikes, aft delar av underlaget Eli obetackta av kvicksilvret, vilket skulls hava valclsani vatgasutveckling till foljd. By using the device described above, the device is not even covered by the mercury, which should have valclsani hydrogen gas development as a result.

Man Ear nu funnit, aft ett blottlaggande av delar av underlaget Oxen kan undvikas, am man utan hansyn till den form det nedflytande kvicksilverskiktet skulle antaga vid frit fall under inflytande av ytsphnningen och fallaccelerationen under hansyntagande till friktionen mot underlaget, blott sorjer for, aft underlagets tvarsnitt utgora statna, sig kontinuerligt kriikande linjer, corn likna varandra, t. ex. Oro likformiga eller kongruenta. Uppfinningen avser en anordning for elektrolytisk sonderdelning av saltlosningar enligt amalgamforfarandet med vertikalt anordnade katocler och kannetecknas av ett med ett brh,ddavlopp forsett, en slat yta uppvisande inetallunderlag, som uppvisar for-men av en sluten, vertikalt staemde mantelyta under iakttagande av aft mantelytans horisontaltvarsnitt bilda kontinuerligt krokta, eventuellt inedelst raka linjer forbundna linjer. Det hr alltsh joke lhngre nodvhndigt, aft ytan avsmalnar nedht, utan den kan enligt uppfinningen fastmer Oxen hava formen ar tvh pla,nparal lella, plana, vid sidokanterna medelst halvcylindrar forbundna ytor. It has now been found that an exposure of parts of the substrate can be avoided if, without regard to the form the descending mercury layer would take in free fall under the influence of the surface and the fall acceleration during exposure to the friction against the substrate, only worries of the substrate cross-sections constitute static, continuously creaking lines, corn resembling each other, e.g. Concerns uniform or congruent. The invention relates to a device for electrolytic probe division of saline solutions according to the amalgam process with vertically arranged catocols and can be characterized by a smooth surface provided with a brh, dead drain, which has the shape of a closed, vertically tuned mantle surface. form continuous crooked, possibly inwardly straight lines connected lines. This joke is no longer necessary, since the surface tapers downwards, but according to the invention it can be fixed. The Taurus has the shape of two flat, parallel, flat, at the side edges by means of half-cylinders connected surfaces.

Aft ett blottlaggande av delar av underlagets yta genom cid nedflytande kvicksilvret idea holler intracler vid anvandning av dylika ytor med slutet tvhrsnitt, far sin forklaring dkav, aft kvicksilverskiktet tack vane sin ytspanning ar i •stand aft upptaga, en vise tvarspanning utan sonderslitning av dess sammanhang. After exposing parts of the surface of the substrate by cid-descending mercury, the idea is intrinsic when using such surfaces with a closed cross-section, its explanation is dull, because the mercury layer is accustomed to absorbing its surface tension, a wise transverse tension without tearing its context .

Pa den bifogade ritningen htergives p schematiskt aft i fig. laoch lb en lamplig utforingsform av underlaget enligt uppfinningen, varvid fig. lautgor en vy ovanifran och fig. lbb ett vertikalsnitt genom metallunclerlaget i riktning av langdaxeln i fig. la. Metallunclelaget kir kvicksilverkato den bestar av tv5, parallella, ph ett avsthnd av 60 mm. lodratt st&- encle jhrnbleck a av 800 mm. bredd. och 1500 mm. hOjd, sorn vid sina sidokanter forbindas medeist 1500 mm. hoga halvcylinderformiga bleak b. 40 mm. under den fullkoniligt plana och horisontella kanten c, Over vilken kvicksilver flyter, Or en batten d fastsvetsad. For stromtillforseln uppbhr bottnen d stavar e och Tor f med hhl i, genom vilka kvicksilvret tillfores katoden. Shirai stamina e som Toren f aro, i den man de komma i beroring med elektrolyten, elektriskt isolerade, exempelvis me-deist overdrag g av gummi. Rummet h mellan bottnen d och braddavloppskanten c tjanar aft upptaga kvicksilvret. Aven i foreliggande fall kan katodens anvandning i drift i hog grad underlhttas enligt uppfinningen genom foreghende preparering av bleckytan i och for battre vatbarhet genom det nedflytande kvicksilvret, foretradesvis genom overdragning med tunna skikt av i kvicksilver losliga metaller, shsom tenn, koppar, bly eller annat. Derma, htgard Or andamalsenlig framfor alit nar jam n valjes som material for katodunderlaget, di det eljest hr forhhllande-vis svkt att fullsthndigt tacka jhrnet med kvicksilver. — In the accompanying drawing, Fig. 1a and 1b schematically show a lamp embodiment of the substrate according to the invention, Fig. 1 showing a view from above and Fig. 1b a vertical section through the metal layer in the direction of the longitudinal axis in Fig. 1a. Metallunclelaget kir mercurycato it consists of tv5, parallel, ph a distance of 60 mm. vertical st & - encle jhrnbleck a av 800 mm. width. and 1500 mm. hOjd, sorn at its side edges are connected medeist 1500 mm. hoga semi-cylindrical bleak b. 40 mm. below the fully conical flat and horizontal edge c, Over which mercury flows, Or a batten d welded. For the power supply, the bottom then supports rods e and Tor f with hhl in, through which the mercury is supplied to the cathode. Shirai stamina e as Toren f aro, in the man they come in contact with the electrolyte, electrically insulated, for example me- deist coating g of rubber. The space h between the bottom d and the brad drain edge c serves to absorb the mercury. Also in the present case, the use of the cathode in operation can be greatly facilitated according to the invention by prior preparation of the tin surface in and for better wettability by the flowing mercury, preferably by coating with thin layers of mercury-soluble metals, such as tin, copper, lead or other . Thus, htgard Or andamalsenlig over alit nar jam n is chosen as the material for the cathode substrate, in which it is otherwise relatively difficult to completely thank the iron with mercury. -
