PROCESS FOR EMULSIFYING RESIN SOAP IN WATER.

Specification of Reissued Letters Patent.

Reissued Oct. 23, 1906 Original No. 781,506, dated January 31, 1905. Application for reissue filed June 9, 1906. Serial No. 321,070-

To all whom it may concern.-

Be it known that 1, MAX ERFURT, a subj ect'of the Emperor of Germany, residing at Strau pitz, near Hirschberg, Silesia, Germany, have invented a new and useful Process for Emulsify'ing Resin Soap in Water, of which the following is a specificati on.

The manufacture of sizing out of resin soapi. e., an emulsion of resin soap with hot wateris the more difficult the more free resin is contained in the resin soap. In the ordinary processes of manufacture separation of raw resin takes place, causes considerable loss of product, and may render the resulting sizing unfit for use.

The present invention now has for its ob ject a process by means of which resin soap with an admixture of as high as one hundred per cent. free resin can readily be emulsified in hot water. The result is a resin soap of a very high percentage of free resin and of correspondingly good gluing properties, also a great saving 1n alum.

The accompanying drawing is a side elevation of the apparatus employed in my improved process.

In carrying out the invention the resin soap is heated in a suitable receptacle 1 by means of steam-coil 2 or some other appro priate source of heat and is then conducted through the connection 3 into a measuring-- supply pipe 8. By the steam entering the solution within this mixer or injector the temperature of the resin-soap and water solu tion is still further enhanced, so that the final temperature of about 212 Fahrenheit is obtained. The heated resin-soap and water solution is then atomized. by means of the steam-pressure behind it within the mixing device, injected into the water contained in the emulsion-vat, and emulsified therein. The water used in the mixer is preferably taken from the emulsion-vat 6 by means of a pipe 9, connected. to the mixer or injector and in communication with the vat, the supply of water being steadily fed to the vat by a supply-pipe 10 for the purpose of keeping up ...%1-0:01VQ agitation, thereby aiding the emulsifylng process The result of the described process is a non-settling sizing, which is next con ducted into the reservoirs, from where 1t. is run off into the-rag-enginc.

What I claim, and desire to secure by Letters Patent, is-

Process for emulsifying resin soap in water, consisting in heating resin soap, atomizing and mixing. it with hot water under stearn, pressure Withinan injector, raising the temperature of the mixture, and injecting this eated mixture into water, for the purpose of bringing about perfect emulsion, substane tially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

MAX ERFURT.
