Title: Telephone system for wideband signal cable network - is distributed in several planes and widely branched
Inventor: SCHOEN DIETMAR
IPC: H04B3/44
Filed: 1973-09-18
Abstract: The network is provided with line, branch and terminal repeaters as loads. All loads are connected in parallel to a common d.c. supply voltage, and supplied from several distant points. A power pack connected to the local supply network supplies a terminal repeater for subscribers connected at each branching point to a following network plane. It is converted to a remote power supply unit which supplies the network from each branching point in addition to the central remote power supply. The power supply to the final amplifiers on the branch points is widened to a neighbouring network for long distance fed apparatus. A greater purity of operation is thereby given because for each point of the network a supply from at least two points is possible.

IPC: C25D7/04
Filed: 1973-11-07
Abstract: In an appts. for electrodepositing metal on an object having a round cross-section, esp. a roll, in which the object, connected as cathode, is rotated in electrolyte and is surrounded by a perforated double-walled anode container which is made of expanded metal and contains pieces of the metal to be electrodeposited, the anode container is made of a number of segments between which are arranged a number of titanium-clad electrical conductors, conforming to the shape of the outer container wall and forming a unit with this wall, and part of the periphery of each conductor projects into the space between the container walls. The arrangement ensures the current density required for faultless deposn. and allows use of large conductors so that more anode material is contacted and less dead space is created near the outer container wall.

Title: Silicon rectifier overvoltage protection - incorporates two mutually coupled air cored coils as inductors
Inventor: ROTH RUDOLF
IPC: H02H9/04
Filed: 1974-05-16
Abstract: A circuit to protect silicon rectifiers against harmonic overvoltages superimposed on the supply employs cancellation of the voltage spike instead of a bypassing arrangement. The required result is achieved by putting an air cored choke (1) in series with each a.c. supply line to the rectifier (4). These chokes are closely coupled magnetically but electrically isolated from each other. A suitably rated capacitor (2) is connected across the a.c. lines on the rectifier side of the chokes. Non-linear resistors (3) or similar devices may still be used to limit slower rising peaks. The circuit also prevents the feed back of commutation spikes into the supply system.
