Abstract: The present invention is disclosing an automated retractable information display device for vehicles. Display device may be configured to mount detachably at interior or exterior of vehicles. Display device may comprise a housing configured to receive information associated with a first user for viewing thereof from exterior of vehicle upon a request from a second user, a transceiver configured to receive an actuation command from a control element via a communication network, and an actuating element configured to retract in and extend out information automatically based on received actuation command.

Abstract: A baffle for use in a circuit breaker includes a first baffle mechanism and a second baffle mechanism. Each of the first and second baffle mechanisms includes a base, a plurality of elongated members supported by the base, and cross-pins or other elongated members for supporting the base of one of the baffle mechanisms substantially parallel to the base of the other baffle mechanism. The elongated members of the first and second baffle mechanisms are interleaved to form a labyrinth.

Abstract: A circuit breaker combines DC and AC arc extinguishing capabilities by associating a magnet applied permanently upon the outside wall of the insulating housing of the breaker and a U-shaped member of ferromagnetic material lodged and held inside the housing, both being in line with the centrally disposed arc chamber and the fixed and stationary contacts thereof.

Abstract: A multi-phase circuit breaker characterized by a plurality of phase compartments separated by spaced barriers, a circuit breaker structure within compartment and having separable contacts, manually operable handle within one compartment and including a crossbar extending laterally through the compartments and barriers and each barrier having a removable portion that is retained in place by an overlying portion of a handle.

Abstract: A circuit breaker with an arc gas vent baffle characterized by a molded insulating housing containing circuit breaker and an arc quenching chamber, the housing having walls forming a compartment containing a terminal, the walls having spaced vent openings communicating with the compartment one of which openings is covered with a baffle to turn aside the flow of gases, and the baffle being yieldably mounted to permit access through the opening from the outside of the housing.

Abstract: A circuit breaker with arc chamber vent characterized by a molded insulating housing containing circuit breaker means and an arc quenching chamber, the housing having wall means forming a compartment containing a terminal, and the wall means having gas vent opening communicating between the chamber and the compartment and a tubular wall surrounding the terminal for preventing any arc gases exhausting from the chamber into the compartment from causing electrical breakdown between the terminal and any proximate conductor.
