KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Schon vielfach sind Versuche angestellt worden, um das grofse Gewicht der Bleisammler durch Verwendung von sogenannten Masseplatten zu verringern, welche nur aus der wirksamen, von einem Bleirahmen umgebenen Masse bestehen und kein Bleigitter und dergl. besitzen. Diese Versuche sind jedoch bisher an der mangelhaften Festigkeit der Masse gescheitert, welche man vergebens durch Anwendung von Bindemitteln zu vergröfsern versuchte. Als solche Bindemittel sind Theerdestillationsrückstände, Harze (vergl. D. R. P. Nr. 26453), sowie Gummiharze, Kautschuk, Guttapercha und dergl. (D. R. P. Nr. 45136) vorgeschlagen. Diese Vorschläge haben sich in der Praxis jedoch nicht bewährt. Denn die Bindemittel werden durch den Einflufs des elektrischen Stromes vielfach in kurzer Zeit zersetzt und hinterlassen eine zwar poröse, aber bröckliche Masse ohne genügenden Zusammenhang. Ein weiterer Uebelstand, welcher sich besonders bei der Verwendung von Gummiharzen bemerkbar macht, liegt darin, dafs die Leitungsfähigkeit ganz bedeutend geschwächt und die Formirung sehr erschwert wird, weil die Theilchen der wirksamen Masse von der isolirenden Harzschicht überdeckt sind.Many attempts have already been made to find out about the great weight of the lead collectors by using so-called ground plates, which only consist of the effective ones, surrounded by a lead frame Consist of mass and no lead grid and the like. Have. However, these attempts are so far failed due to the insufficient strength of the mass, which one in vain by application of binders tried to enlarge. Such binders are tar distillation residues, Resins (see D. R. P. No. 26453), as well as gum resins, rubber, gutta-percha and the like (D. R. P. No. 45136) suggested. However, these suggestions have not proven themselves in practice. Because the The influence of the electric current often causes binding agents to become in a short time decomposes and leaves behind a porous but friable mass without sufficient cohesion. Another disadvantage, which is particularly noticeable when using rubber resins, is that that the conductance is considerably weakened and formation is very difficult because the particles of the active mass are covered by the insulating resin layer.
Die vorliegende Erfindung besteht nun in der Verwendung von Bernstein bezw. ähnlich zusammengesetzten fossilen Harzen als Bindemittel. Dadurch wird eine grofse Leitungsfähigkeit, Festigkeit und Geschmeidigkeit der Masse erzielt, so dafs die Masseplatten einen sehr starken Entladungsstrom ohne Schaden abgeben können und auch gegen Erschütterung widerstandsfähig sind. Ferner geht die Formirung leicht von statten, doch bedürfen die Platten einer vorgängigen Ansäuerung. Vermöge der chemischen Zusammensetzung des Bernsteins (seines hohen Gehalts an Bernsteinsäure und öligen Stoffen) bildet sich eine feste Verbindung mit den Metalloxyden, welche sehr widerstandsfähig ist. Ein Theil des Bindemittels wird durch die Jonen zersetzt, so dafs die Masse auch genügend porös wird. Der Bernsteinzusatz hat in chemischer, elektrischer und mechanischer Beziehung einen guten Einflufs.The present invention consists in the use of amber BEZW. similar composite fossil resins as binders. This results in great conductivity, strength and flexibility of the Ground achieved, so that the ground plates have a very strong discharge current without damage can give off and are also resistant to vibrations. Furthermore, the Formation is easy to do, but the plates require prior acidification. Fortune the chemical composition of amber (its high content of succinic acid and oily substances) a firm bond with the metal oxides is formed, which is very is resilient. A part of the binding agent is decomposed by the ions, so that the mass also becomes sufficiently porous. The amber addition has in chemical, electrical and mechanical relationship a good influence.
Zur Ausführung des Verfahrens werden die Mennige bezw. die sonst verwendeten Metalloxyde in eine heifse Lösung von Bernstein eingetragen, bis eine teigartige Paste entsteht. Als Lösungsmittel wird am besten eine heifse Mischung von Alkohol und Terpentinöl benutzt. Darauf wird der aus Hartblei bestehende Rahmen, welcher zweckmäfsig rinnenförmige Querschnitte hat, auf eine Glasplatte gelegt, und die Paste in warmem Zustande eingestrichen. Die Anwendung von höherem Druck ist nicht erforderlich. Sodann werden die Platten in mäfsiger Wärme getrocknet, bis das Lösungsmittel verdunstet ist, und hierauf einige Tage in einem Bade aus verdünnter Schwefelsäure angesäuert. Nachdem sie in das Element eingesetzt worden sind, wird die Formirung vorgenommen.To carry out the process, the red lead bezw. the otherwise used metal oxides added to a hot solution of amber until a dough-like paste is formed. A hot mixture of alcohol and turpentine oil is best used as a solvent. The hard lead frame, which is expediently trough-shaped, is then placed on it Cross-sections, placed on a glass plate, and painted the paste while it was warm. It is not necessary to use higher pressure. The plates are then dried in moderate heat until the Solvent has evaporated, and then a few days in a bath of dilute sulfuric acid acidified. After they have been inserted into the element, the formation performed.
