PROCESS AND APPARATUS FOR PRODUCTION OF A SUBSTANCE HAVING A NAGREOUS AND CHATOYAN'J.

Original application flied November 19, 1926,Seria1 No. 149,444, and in France November 21, 1925.

Divided and this application flied March 22, 1928. Serial No. 263,948.

The present invention relates to a process and apparatus for the obtainment of nacreous and chatoyant substances and 1s a division of my application Serial No. 149,444, filed No- 5 Vember 19, 1926. I

The said process is based upon the use of a transparent plastic mass such, as celluloid, acetate of cellulose, casein, and the like, into which are incorporated by the kneading and mixing rocess certain brilliant partlcles such as meta lic particles, mica, vario'us metalhc salts, pearl essence, or the like.

According to known practice, 1f a plastic mass of this kind while still soft is forced througha nozzle this will afford at the dischar e end of the nozzle strips in which the brilliant particles will all be parallel with the surface of the said strips.

For thisreason, the strips have a uniform smooth and brilliant aspect, and their appearance and lustre, in the case of pearl essence, resembles the real pearl rather than the moth er of pearl, due to the absence of all streaks.

The present invention is based upon the 26 fact that if there is an obstacle in the nozzle which hinders the issue of the said plastic mass, this obstacle will cause eddies or whirls in the said mass which will subsist for a certain time and will cause a partial confusion 39 of the said particles. The particles whereof the direction is changed, and which have now become more or less oblique to the surface of the strip, will reflect the light indifferent directions and will give to the eye the impres- 5 'sion of streaks, so that the surface of the resultin pear y substance, will not appear smoot ,but will be irregular and cockled, and I may take advantage of this fact to obtain various decorative effects.

Based on the above data, the invention comprises in principle a suitable press in which the plastic mass containing brilliant particles may be raised to the softening temperature by proper means. The said press operates in connection with a special nozzle whose width will depend upon the conditions of. manufacture, and whose thickness may attain one or two centimeters or more, whereby I am enabled to provide strips of a rather considerable thickness. The appended drawings show by way of example a nozzle according'to the invention. The said nozzle is characterized in that on a part of its length comprised between the which is sufficiently abrupt at the rear to produce the desired result.

The nozzle thus formed is adapted for different uses. If the cross section of the nozzle is clrcular or rectangular -it can be used for the manufacture of round a pearly nature which can be used after dryhould it be desired to obtain sheets of pearly substance by cutting up a block which is manufactured by the known process, I employ a nozzle of larger size whose width at least equals the width of the block press. With the use of a nozzle of such size, the lastic substance issues in the form of a thick and of'l or 2 centimeters thickness. This band is cut up, as fast as formed,- into sheets having the size of the block press in use. The pieces thus obtained are piled up in the block press, after which theyare formed into a compact mass by heat and pressure by the known methods, thus producing a block which may be cut into sheets .of the desired thickness.

Having thus described my process and apparatus what I claim as new therein, and my own invention, is:

1. A process for the obtainment of obj ects or square rods of of a nacreous and chatoyant aspect, in which a soft plastic substance containing brillinat partlcles is forced through a nozzle, an obstacle'being placed in the said nozzle of such nature as to change the direction of the said brilliant particles.

2. 'An apparatus for the obtainment of obj ects of a nacreous and chatoyant aspect by the use of a soft plastic substance containing brilliant particles, said apparatus comprising a nozzle having at least oneinwardly extending projection disposed between the inlet and the outlet of said nozzle, said" projection being adapted to form eddies in the stream of the plastic substance in circulation.

3. An apparatus for the obtainmnt of a adapted to produce eddies in the circulating nacreous and chatoyant aspect by the use of substance, said portion commencing at a cera soft plastic substance containing brilliant tain distance from the intake end of the nozarticles, said apparatus comprising a @nozzle zle and ending at a certain distance fromthe 5 1n which a portion of the length between its outlet, which latter distance is sufliciently ends is provided with projections. small to prevent all destruction of the eddies,

4. apparatus for the obtainment of a substantially as described.
