Title: HV current transformer with dielectric voltage divider - has partial insulation on capacitors surrounding HV conductor in insulating tube, held by external insulator and disc
Inventor: HERMSTEIN WOLFGANG DR ING
IPC: H01F38/28
Filed: 1973-06-13
Abstract: Surrounding the H.V. feeder is a toroidal core supported by an unearthed metal column filled with insulating oil. The feeder passes transversely through the cent re of the toroid and coaxially with both is a metal cylinder so that the cylinder and H.V. conductor form the horizontal arm of a cross. On one side only of the cross arm are capacitors placed between the metal cylinder and an outer insulator. The capacitors are short annular sections placed adjacent to each other, extending from one side of the toroidal core to the outer extremity of the cross arm. They serve to modify the voltage distribution between the two parts of the split dielectric. As this structure is placed on one side of the core only, it is possible to assemble or dismantle the transformer by inserting or withrawing the arm in one piece.

Title: Steering column mounted direction flasher - with integrated circuit flasher control mounted inside flasher switch
Inventor: ERDELITSCH HERBERT
IPC: B60Q1/34
Filed: 1974-11-13
Abstract: The linkage and electric connections in a steering column mounted flasher switch can be expensive and complex. A simple solution is to use an integrated circuit flasher control which is mounted inside the switch and which is touched by special stops on the switch stalk. The stalk operates piezo electric supplies to the circuit to provide flasher impulses down one of two wires. The wires lead to switching relays in the lamp supply circuit to operate the selected signals. The switch layout is thus greatly simplified, and the use of integrated circuits is ideally suited for mass production.
