  • Publication number: 20020070564
    Abstract: A door closer includes a latch that engages with a striker and first and second ratchets that engage with the latch. When the latch receives the striker and rotates from an initial position to a fully latched position, the door is moved to a fully closed position. When the ratchets disengage from the latch, the latch returns from the fully latched position to the initial position. The striker thus disengages from the latch, and the door moves from the fully closed position to a released position. After the ratchets disengage from the latch, each ratchet is held at a position at which the ratchet cannot engage with the latch unless the door is located at a predetermined position separate from the released position in a door opening direction.

  • Patent number: 5452170
    Abstract: A commutation type DC breaker having a commutation circuit electrically connected in parallel to a main contact. The main contact is connected between a DC power supply and a load. The commutation circuit is a series circuit of a commutation capacitor, a reactor and a commutation switch, with an energy absorption device electrically connected in parallel to the main contact. A switch or a breaker for preventing the flow of commutation current from the commutation circuit to the load in a non-load opening mode is connected between an electrical connection point (P), of the main contact and the commutation circuit, and the load and is opened substantially simultaneously with the opening of the main contact, or before the closure of the commutation switch. In this manner, the safety on the load in the non-load opening mode is enhanced.
