Tt is quite generally known that condensers of high capacity consistent with small volume may be manufactured by coatingthe metal conductors of the condenser with a dielectric p in fluid form. This coating in the past has been allowed to dry, after which the conducting layers were brought into their final shape by rolling or forming. In a condenser manufactured in this manner there is a pos- 1n sibility of moisture penetratinginto the interior of the roll and in addition a special binder for holding the roll must be provided.
The present invention overcomes the objections to the former process and consists l5 of the coating of the conducting layers of a condenser with cellulose-ether and in rolling the whole into a rigid mass before the coating gets solid.
This causes the various layers of the roll 2a to be intimately connected and thus form a non-hydroscopic, completely enclosed mass which canonly be severed by damaging the parts, and consequently the penetration of moisture into the interior of the roll is effec- 25 tively prevented.
According to the invention the coated layers are preferably partly dried beforehand so that the layers adhere together immediately on being coiled up, whereupon after reaching 3a the desired size, they are pressed, and, due to the adhesive action form a solid moisture proof mass.
The process-of manufacturehas been diagrammatical-ly 0 illustrated in the accom- 5 panying drawings,in which Fig. 1 illustrates the manner of applying the dielectric to the condenser elements, as well as the manner of.
winding; while Fig. 2 shows front and top views of the condenser complete.
The rolls 2 and 3 represent the source of supply of the condenser element material, which is drawn thru a container 4 of cellulose-ether as it is wound on an arbor 5. When sufficient of the condenser material has been wound upon the arbor to produce a condenser of the desired capacity the condenser is simply torn or, removed from the arbor, and compressed into the form shown in Fig. 2, before the coatin 59 forming a soli moisture-proof condenser.
has completely dried,'thereby ll claim:
1. The process of manufacture of condensers consisting in the coating of the conduc tive layers with a solution of cellulose-ether, exposing the coated layers to the atmosphere until partly solidified and in then rolling the layedrs into a mass before the coating becomes soli 2. The process of manufacturing condensers consisting of coating the conductive material with an air drying insulating material, exposing the coated material tothe at mosphere until partly solidified and in then rolling the coated material into a mass before the insulating material has fully dried so that when :drying is" completed the condenser will be a solid mass.
3. The process of manufacturing an electric condenser, which consists of coating the elements of the condenser in a dielectric, bringing the elements into contact with air under normal temperature until the dielectric is partly solidified and of thereafter winding and compressing the condenser elements into a concentrated mass before solidification occurs.
4. The process of manufacturing an electric condenser which consists solely of coating the metallic elements of the cohdenser with an air drying dielectric, and in'winding the elements into a single mass after the dielectric coating has become partly solidified.
In witness whereof, I hereunto subscribe my name this 15th day of August, A. D. 1928.
