DIAPHRAGM AND ME'ZTHGID F TMZAZJ Application filed October 3,

To all 10. mm it may cmIcw-n: l Be it known that l, HEINRICH llnrrz, a subject of the Emperor of Gcrnniny, residing l at No. liingtlon road, ll'ostllanipsteiul, in the county of Illiddlescx, England, chcmisl, l

have invented certain new and useful Int-- movements in Diaphragms and Methods ol' ills-king the Same, of which the following is a specification.

Diaphragms for electrolytic cclls unule of various kinds of fabric such as asbestos cloth, l nit 'ntod cotton cloth or the like are satisfactory in respect ol the *l'zu-t that they oller comparatively little res stance to the passage of the electric current, but they are not cllil cient in respect of their permeability to cloctrolytes which are to he kept separate.

My invention relates to fabrics and a. method of modifying the Stunt when designed. to be usoil for tho purpose in questii'm by impregnating thorn successively and if necessary repeatedly with a solution of a double cynnitl or a mixture of double cynnids and a solution of a metallic salt or mixture of metallic snlts, the double cyunid and metallic salt being such that when the solutions lllQG-l. in the fabric a deposit is lcrnicd in the pores thereof which has the desired client on tho permeability of the fabric.

Particularly suitable for the invention are For instance a textile diaphragm of asbestos cloth may bo dipped into :1 solution oi nlknli l'errocyunid orlerricynnid and then into n solution of copper sulfate.

Vl hcn the diaphragm is to be uscd for an cloctroiytic cell wherein a solution. 01 :1 molzillic suit that iornis an insoluble doublc cynnid is to bo (llft'l'l'Ulyiit-ltl it is njcl'vrublc to usov a solution ol this snlt. us one ol lhosc with which the i'lull! is in be iinprngnnitcd and :1 siinph: nnuuu-r of doing this is to sntrurulc the cloth first with a concentrated solution ol' alkali lorroc viuiid or 'l'crricynnid and thou vitlu-r bcl'orc or zd'tcr it hus dried. to phu'c il in )osilion in thc solution in tin (!lQClIUl \'l'h-, cull whcrcupon lhc desired deposition occurs whilc the cloth in place.
