Patents by Inventor Emil Sturm

Emil Sturm has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4672289
    Abstract: A circuit arrangement in which an a.c. load is connected in series with a capacitor unit suitable for a.c. connection. In such a circuit arrangement, the use of capacitors suitable for d.c. operation is made possible by the fact the capacitor unit is made up of two polar capacitors which are connected in series with the load in such a way that the capacitors are interconnected with matching poles, either directly or by way of the load with matching poles, as well as by the fact that a rectifier diode is connected to each capacitor, with the cathode of the rectifier diode being connected to the positive pole of the respective capacitor and the anode being connected to the negative pole of the respective capacitor.

  • Patent number: 4672290
    Abstract: A circuit arrangement is disclosed in which a capacitive unit suitable for a.c. operation is connected in series with an a.c. load. An extension of the life of the capacitors can be achieved by having the capacitor unit consist of two capacitors connected in series either on the same side of the consumer or on opposite sides of the consumer, and that a separate rectifier diode is connected in parallel with each capacitor. Both rectifier diodes are connected with its forward direction opposite with relation to each other. This prevents reverse polarity voltage and charge, as well as reduces the duty cycle by fifty percent, thereby polarizing electrolytic capacitor life.
