IWAN EMIL LANHOFFER AND OSCAR EDMOND LANHOFFER, 0F IPARIS, FRANCE, AS- SIGNORS TO SIMON J. DANNENBERG OF NEW YORK, N. Y.
PROCESS OF PRODUCING HOMOGENEOUS, MOLDABLE POWDERS FROM FIBROUS CEMENTS.
No Drawing.
1 '0 all whom it may concern Be it known that we, IWAN EMIL LAN- HOFFER, a citizen of the Republic ofFrance,
Application filed March 18, 1925. Serial No. 16,569.
We then use this powder either just as it 4/ and a resident of Paris, France (post o e address 10 Avenue de la Grande Armee), wheel itself can be used to produce dlrectly and OSCAR EDMOND LANHOFFER, citizen of the Republic of France, residing at Paris, France (post-ofiice address 10 Avenue de la Grande Armee), have invented certaln new and useful Improvements in a Process of Producing Homogeneous, Moldable Powders from Fibrous Cements, of which the following is a specification.
Whatever the method according to which they are prepared, mortagsflmadeofcement and fibrous materiallia rdly offer absolute homo y. 1 ierto there has been no tvay'to avoid the formation of small bunches of fibres which when such a mortar is spread out in a single layer over a mold plate or other suitable receiving or supporting surface, will of necessity offer points where bothresistance and adherence are not the same as with the rest of the mass.
The object of our invention is to provide a process permitting absolute homogeneity to be imparted to such mortars while doing away with the above mentioned defect.
Such process consists in emovin from a wet mixture of d sintegrated rous ma e1 rial and cement constituting tie mortar a form.
like as the best implement to pow'derizesucli mortar, we reserve the rig 1 use other means such as cylinders striated like files 0r rasps, steel hushed, warped saws, circular saws inclined on their axis of rotation etc., etc, to achieve analogous effects.
Having now particularly ascertained and described the nature of our said invention as well as the manner in which the same is to be performed, we declare that what We claim is:-
1. A process of producing homogeneous, moldable powders from fibrous cements, comprising the steps of forming a wet mortar from fibrous material and cement; eggthe mortar into plate or block form to expel s11 excesswater'tlieiefrom; and then reducing such plate or block to powder Q. A process of producing homogeneous, moldable powders from fibrous cements, comprising the steps of forming a wet mortar from fibrous material and cement; compressing the mortar into plate or block form to expel all excess water therefrom; and then subjecting the plate or block to the action of a rapidly-rotating grinding element to reduce it to the form of a moist powder.
In testimony whereof we afiix our turos.
lWAN EMIL LANHOFFER. OSCAR EDMOND LANHOFFER.
