    Abstract: An electric switch includes a pair of separable contacts operable between open and closed positions with respect to each other. An operator shaft is utilized for moving one of the contacts, and the operator shaft has attached thereto at the opposite end an operator piston which is disposed within an operator cylinder. A chemical operator is utilized for generating a hot gas within the operator cylinder and against the operator piston to cause movement thereof.

    Abstract: A center shaft of a swing lever, connected to a moving contact of a main interrupting unit, is supported by hollow bearings. The center shaft is provided with an engaging portion which is positioned in the hollow space of the hollow bearing and therein connected to a rotating shaft of which the force is partially exerted on a moving contact of a closing resistor device. Therefore, if the gas circuit breaker does not need the closing resistor device, the rotating shaft may be removed. For the gas circuit breaker requiring the closing resistor device, the rotating shaft may be inserted into the hollow bearings. For both cases, the gas circuit breaker is thus able to take the same fundamental construction.

    Abstract: A multi-pole high-power circuit-interrupter is provided having a single common operating mechanism therefor, and having independent pole tripping operation by associating with at least one of a plurality of the pole-units its independent ball latching means, which may be very quickly mechanically released upon a tripping operation associated with the respective one pole-unit to which said ball latching device is connected.Another important feature of the invention is the provision of a plurality of load-release latching balls, which may be quickly released from their latched position by a pneumatic releasing device, which is energized in response to electrical overload conditions existing in the respective pole-unit to provide thereby a tripping operation for the particular pole-unit, to which the ball-latching releaseable device is mechanically connected.Still another feature of the present invention is the provision of a spring-return catch-member in a ball-latch releasing device, which holds the load-release balls in their latched position, and provides a desirable quick relatching operation at the end of the closing operation of the circuit-interrupter.

    Abstract: The invention is directed to a contact arrangement in a compressed-gas circuit breaker such as a blast-piston breaker. The contact arrangement includes two base contacts and a bridging contact member. One of the base contacts is movable as a function of the current to be interrupted and the motion is controlled by two electrodynamic coil systems. One coil system causes a shortening of the gap and the other coil system causes a reverse motion shortly before the zero crossing to establish the quenching distance.

    Abstract: A contact arrangement for an electric pressure-gas circuit breaker for interrupting an electric current includes two stationary contact pieces disposed so as to conjointly define a gap therebetween. A follower contact is arranged on one of the contact pieces in insulated relation thereto so as to be movable in a direction toward the other one of said contact pieces. A bridging contact member is movable between first and second positions for electrically joining the contact pieces in the first position and for running off of the one contact piece when moved in the above-mentioned direction toward the other contact piece to the second position thereby electrically separating the contact pieces. An electromagnetic actuator develops a force to propel the follower contact toward the other contact piece during the opening operation of the breaker. A spring associated with the follower contact receives resilient energy as the actuator means propels the follower contact in the direction toward the other contact piece. The follower contact is connected to the current supply for supplying current to the breaker through the electromagnetic actuator to define a bypass conducting path. The follower contact is arranged in the one contact piece so as to cause the bridging contact member to contact the follower contact when the bridging contact member runs off of the one contact piece thereby commutating the current to the bypass conducting path whereby the electromagnetic actuator becomes energized to develop the above-mentioned force.

    Abstract: The descaling of heater tubes is effected by alternately subjecting the deposited scale to oxidation and reduction techniques. Oxidation is preferably effected in a vaporous atmosphere of 1.0 to 15.9 percent oxygen, and reduction in an atmosphere of 5.0 to 50.0 percent hydrogen. The heater is flushed, after either the reduction step, or after both oxidation and reduction, with steam and/or nitrogen to remove loosened particles of scale.

    Abstract: A circuit-interrupting device having extremely short switch-off times with a pressure chamber designed to contain a quenching gas under pressure and a pair of oppositely opposed contacts guided for a limited movement within the pressure chamber. A spring biases one of the contacts toward the other; and a quick-acting release device, such as a piston ring lock, holds the other contact against the first contact under high contact pressure when the interrupting device is in its switch-on position. The contact that is retained by the release device is biased only by the quenching gas in the switch-off direction. When the release device releases this contact, the two contacts separate from each other very rapidly. The contacts are sealed so that the quenching gas can not escape through the hollow bore of the contacts until they have separated. The release device may be provided with a suitable device to compensate for temperature fluctuations. The actuation of the release device may occur in dependence on the net current in the circuit, so that the separation of the tubular contacts occurs under minimum arc duration and, thus, with minimum switching effort.

    Abstract: A high voltage gas blast circuit breaker is provided with series-connected pairs of contacts, one used to interrupt the circuit being protected, and the other used to close or make the circuit being protected. The contact used for circuit interruption may be operated synchronously to interrupt at or before a current zero. The contact used for closing the circuit may be operated when the instantaneous voltage across the contact is zero, thereby to prevent line voltage surges during closing. The operating circuits for the contacts are at the high voltage side of the breaker and contain a generator driven from ground by an insulation shaft. The operating circuits include a photosensitive switch which is energized by light sources located at ground potential.
