EERMANN PLAUSON, OF HAMBURG, GERMANY, ASSIGNOR TO 1). R. ROTKAN, OF NEW 4 YORK, N. Y.
MANUFACTURE OF ARTICLES FROM PROTEINS.
Ito Drawing.
To all whom it may concern Be it known that I, HERMANN PLAUsoN, Esthonian subject, residing in Hamburg, Germany, have invented certain new and useful Manufacture of Articles from Proteins, of which the following is a specification.
It is known that articles can be manufactured from dried blood, hemoglobin, casein, yeast and the like, but such masses are not stable against water and their resistance to temperature is very small. For this reason it is diflicult and in many cases practlcally impossible to employ such masses for the manufacture of articles,'for example knobs, buttons or the like.
The present invention relates to a process by which it is possible to impart to the articles an extremely firm'structure and to enable them to take a higher polish. This object may be attained by extensive dispersion of part of the material, for example blood, in a suitable dispersion medium, and employing this colloidally dissolved portion as a binding agent for the other dried portion. The dispersion of the blood or other protein mass may be effected-in a suitable rapidly rotating colloid or percussive machine. Various dispersion media can be employed, but I have found that dichlorhydrin is particularly suitable together with other aliphatic alcohols of all kinds especially polyvalent alcohols; phenols are also suitable especially when employed in presence of aldehyde. The blood or protein masses can be first made stable against water by treatment with aldehyde or other tanning agents, and then a portion of the mass as mentioned above can be brought into a colloidal state of division and employed as a binding agent for the main quantity. The dispersion medium can also be diluted with chlorinated hydrocarbons.
It is considered to be novel to transform powdered blood, hemoglobin, casein, yeast and the like protein powders into colloidal dispersion on the large technical scale and it is unexpected that such solutions act as binding agents, and further that they impart an increased strength to the objects referred thereto, and enable such objectsto be given a firm polish.
The process will be understood more Specification of Letters Patent.
Application filed February 8, 1921.
Patented N ov. i, 1921.
Serial No. 443,424.
clearly by consideration of the following examples to which however the invention is not limited.
ground for one half to two hours with 500-800 parts of dichlorhydrin in a colloid mill, such as described in my co-p'ending applications, Serial Nos. 463,619 and 437,117, percussion mill, or the like. In the course of this time, the whole of the blood or hemoglobin is transformed into a completely clear solution. 100 parts of this solution are now mixed with 300-500 parts of finely ground hemoglobin and then the excess of dichlorhydrin is removed by evaporation either in air or better in oacuo at a temperature not above 50 C. The whole is again ground to a fine powder when it can be pressed into articles of the desired shape in warmed molds at 80 to 125 C. at a pressure of 150-300 atmospheres. Instead of blood, a mixture of blood and casein, yeast or the like may be employed.
The stability against water can also be increased by previously tanning the blood mass with aldehyde or other tanning agents, or by allowing aldehyde or tanning solutions to act on the pressed articles which can then be again dried and polished.
Example 2.
are very dark in color and completely devoid of smell, they are extremely hard and strong and can be readily polished highly. The process can be changed in so far as a phenol can be employed alone and if desired as a dispersion medium as in Example 1.
In the same way casein is dispersed by means of dichlorhydrins or phenols and after mixing with further dry casein either tanned or not, the mixture is pressed into articles.
If yeast is employed as raw material, either alone or in admixture with blood, it is preferabl worked up according to Example 2. ish protein can also be made into beautiful articles in the same way.
mixture of diiierent kinds of protein is permissible. F or example a dispersion of casein can be employed as binding agent for dried hemoglobin and so on. The main feature of the process consists in the fact that part of the protein is treated in a non-solvent organic dispersion medium and the colloidal dispersion or organosol so obtained serves as binding agent or adhesive agent for dried protein powder.
I declare that what I claim is 1. A process for making articles from protein which consists in consolidatinga protein powder by a colloidal solution of protein in an organic non-solvent as binder.
2. A process of making articles from hemoglobin which consists in incorporating it with a colloidal solution of protein in an organic non-solvent as binder.
3. The process of making articles from protein which comprises consolidating the protein by a colloidal dispersion of the same protein.
4. The process of preparing a colloidal dispersion of a protein in a suitable organic dispersion medium and then using this dispersion as binder to consolidate the dry protein. i
5. The process of preparing articles of proteins which consists in consolidating a dry protein by a colloidal dispersion of protein and hardening the product chemically.
6. The process of making articles from protein which comprises consolidating the protein by a colloidal dispersion of the same protein in anorganic hydroxylic body. 7. The rocess of making, articles from protein -w ich comprises consolidating the protein by a colloidal dispersion of the same protein in a chlorhydrin.
8. The process of treating proteins alkali, precipitating ing articles rom the treated binder consisting of protein dispersed in an with organic non-solvent.
9. The process of mixing a dry protein and colloidal solution of protein in an organic non-solvent, and forming articles therefrom.
10. The rocess of making articles from protein which comprises consolidatin solid protein by a protein organosol as bin er.
11. The process of making articles from protein which comprises making a protein organosol by intensive mechanical disintegration of protein in an organic liquid, and consolidating dry protein with said organosol as binder.
In witness whereof I have hereunto signed my name this 30 day of Decr., 1920.
