PROCESS OF MANUFACTURE No Drawing.
To all whom it may concern Be it known that I, JEAN Rosnx, a citizen of France, residing at Rue Pigalle, Paris,
France, have invented certain new and use- 1 ful Improvements in Processes of Manufacture of Impregnated Material, of which the following is a specification.
This invention relates to a process. of
manufacture of an unalterable and insulat ing impregnating material and application of same. v v
The present process may involve the use of the process of my pending application Serial Number 783,814, or important steps thereof.
The process of this invention consists in the manufacture of a perfectly impermeable material that isboth insulating and unalter able, and comprises the application of this material on all kinds of rigid or flexible supports to be used as water-tight or nonconducting supports or for electric insulation and the like. p
The raw material consists of coal tar and its various neutral liquid and heavy constituents that by distillation or partial oxi- The tar isfirst heated so as to remove by known methods the caustic substances and a part of thecrystallizableeasily volatilized products that it normally contains (phenols,
naphthalene, etc). The liquid and heavy products for instance, water, naphthalene,
naphthalene oils, creosote and creosote oils,
carried over during this elimination are separated by known means (such as by one or more of the steps of sublimation, crystal- '-liz ation, and treatment with chemical re- 4 agents-,)' from the light and caustic products and the crystalline substances mixed therewith. The liquid, heavyand non-caustic or neutral constituents separated in this man- The treatment by oxidation must be kept up Specification of Letters Patent.

until the product obtained has the consistency and properties required: 2'. 6., until it has acquired a high degree of resiliency and a high softening point and has been rendered unalterable by chemical reagents or the action of the atmosphere. The insu lating and plastic material obtained in this manner and melted at a high temperature can then be used for impregnating by steeping or coating any permeable substratum such as paper, card board, felt, tissue of any kind, poiousterracotta, etc., that 'is thoroughly penetrated by the insulating material. The support chosen which may be rigid or flexible but must be permeable, is
impregnated according to its nature and that of the tar treated, with the liquid, neutral and heavy constituents that were separated oif during the'first treatment above 'referred' to, part of these constituents having been put aside for this purpose. The excess of these substances is carefully eliminated by compression and wiping ofl and the supports prepared in this manner are submitted tages over the old methods :the perfect I penetration of the insulating substance into the porous material used as a" support; the
great elasticity of the product so that without breaking it can undergo the most abrupt v deformations to which the 'non rigid sup ports may be subjected; the unalterable nature of the coating for'gan almostindefinite length of time; the resistance to atmospheric action and chemical reagents without any marked tendency to become brittlewhen I cold or sticky when hot; the possibility of impregnating the paper, felt, tissue of any kind, etc., on both sides without subsequently causing the surfaces rolled up or brought in contact' with one another to stick even under high pressure and in the absence of an accessory absorbent such as A talc, sand, canvas with large meshes and the like.
What I claim is: 1. Aprocess for the manufacture of an unalterable elastic and insulating impregnating product and' irnpregnating supporting materialfconsisting in treating coal tar by heating to remove its caustic and easilyvolatilizable crystalline substances, adding neutral oil to the tar, oxidizing themixture by air, coating the. support materialwlth the product, and subsequently cooling the final product with air.
2. A process for the manufacture of an unalterable elastic and insulating-impregnating' product and impregnating support: ing material consisting in treating coal tar by'heating to remove its caustic and easily ,volatilizable crystalline substances, by heating and adding to the residue heavy neutral oil, thereupon submitting the mixture of tar co ie s: this patent may be obtained for tion of air, impregnating the supporting material by' steeping said material in the oxidized insulating and plastic product obtained While heating the latter, and subsequently cooling the product by a current of air so as to cause the impregnating product to oxidize and'solidify owing to the comparatively high temperature of solidificafive cents each, by addressing the Commissioner of Patents, i Washington, G. 7
