.To all whom it may Concern:
Be it. known that l, lliin'rrn Hosmirnw, a citizen oi: tl'ie German Empire, residing at Berlimlsliarlottenburg, Germany, have 'mvented certain new and useful Improvements Manganese-Peroxide nodes, of which the following is a specification.
My inventionrelates to improvements in manganese peroxide anodes which are made according to the process forming the subject matter of my copending patent application Ser. No. 662,754 led on 14th September, 1923. The invention consists in the anode itself as a new article of manulfn the drawing two difiere-nt examples of the new anode are given. Fig. l shows one construction in side elevation and Fig. 2 in a vertical section. The Figs. 3 and 4 show the upper part of the other example also in elevation and vertical section.
The improved anode consists of a carrier plate l which determines the shape of the iinislied anode and consists of a substance which is in regard to the object in Viewy chemically and also electro-chemically indifferent. To this carrier the manganese peroxide is applied in such a manner that a coating on the surface of the carrier is produced. This coatingr can penetrate into the carrier in such a manner that it is saturated with the manganese peroxide. ln this event also the peroxide will form a dense coating on the surface of the carrier. Fig. 2 shows a carrier l of porous material, for example infusorial earth. which has been saturated with manganese nitrate and tlien burnt at a, temperature over 100D. The granulous material of the anode has been filled by the manganese nitrate which is decomposed in the burning:Y process and converted into the manganese peroxide. Near the surface of the carrier the peroxide forms a dense coatingr 2 on the carrier.
As sliovvn in Fig. l the surface o the carrier is roughened at 3 for the purpose of better securin the manganese peroxide.l
Before app ying the coating of the mangancse' nitrate to the carrier it may be mixed with pure amorphous manganese ore and thecarrier can be saturated or pasted with this mixture. The amorphous manganese ore is then a good and cheap substitute for a part of the expensive crystalline manganese peroxide.
The conductivity of the manganese peroxide snode may be improved as Well known by an electrolytically produced coating flead peroxide. This coating 4 is shown in Fig. 2. l
The contact carrying the current to-the anode consists of a. piece 5 of carbon or graphite which receives the upper end 6 of the carrier in a groove 7. The lower edges of the sides of the contact piece are provided with teeth. 8 meshing with.' corresponding teeth along the upper ed es of the carrier 1 which is somewhat en arged at this part. Into the side parts of the contact 5 and the upper part 6 of the carrier bolts 9 of carbon are inserted. When Saturating or impregnating the carrier in the inverted vertical position with the mangianese nitrate or when applying the paste and burning the carrier in this position a small portion of the nitrate flows between the contacting surfaces of the contact piece and the carrier and makes a very good Contact between them. The coating of lead peroxide 4 is also passed over the point of junction between the carrier and the Contact piece 5. In this manner an intermediate resistance to the passage of the electric current is effectively avoided. y
After thecarrier has been united with the contact piece 5 by burning side pieces 10 of paraiiinated carbon are fixed to the contact piece by metal plates 11 and screw bolts 12. These paraiiinated pieces 1() are provided for the purpose of preventing the electrol te from ascending to the metal parts.
Y hat I claim as In invention and desire to secure by Letters lgatent is l. Anode of manganese peroxide for electrolytic purposes, comprising a. carrier for the peroxide havingr the shape of the anode and consisting of a substance which in regard to the object in view is chemically indifferent.
2. Anode of the type described, consist-v ing of a carrier in shape of the anode having a dense coating of manganese peroxide.
