  • Patent number: 9837222
    Abstract: An exemplary working cylinder for a drive of an electric circuit breaker includes a base that includes a cylinder head and a cylinder body that are connected to one another. Additional components are fastened to the cylinder head as a core piece of the drive, and a thrust ring is guided on an outer surface of the cylinder body. The thrust ring compresses mechanical springs in the mechanical resilient energy storage device by way of a storage piston in a storage module.

  • Patent number: 9111467
    Abstract: Provided is a sealing system for sealing of doors of transport vehicles comprising at least one door with at least one first electrical contact and a corresponding door frame with at least one second electrical contact, where the first and the second contact are arranged on the same side of the door and the door frame and are electrically connected to build an open electrical circuit, and a seal to be attached to the closed door and the door frame suitable to close the open electrical circuit between first and second electrical contact in order to indicate the closure of the door. Additionally provided is a portable logging device for recording the sealing of doors as used by the sealing system and to a method to operate such a sealing system.

  • Patent number: 8082765
    Abstract: A device (1) maintains a locked and closed state of a space separating device (2) in a releasable manner, in particular a protective device of a machine (4). The device has a first part (6) with an opening and a second part (8). The parts are movable relative to one another. The opening is at least partially closable. The device (1) includes a latch (18) for locking the closed state of the space-separating device (2), a holding element (30) for keeping the latch (18) in the latched position, and a release element (36) for releasing the catch of the latch (18). The catch of the latch (18) may be lifted by a rotational movement of the release element (36) relative to the latch (18).

  • Patent number: 7985934
    Abstract: A front-loading clothes dryer, a horizontally pivotable door is secured in its closed position against accidentally opening by a latching closure. Moreover, the door is connected to a safety switch which cuts off or re-establishes power supply for the clothes dryer depending on whether the door is in the open or in the closed position. The object of the invention is to ensure that the switching function remains matched over the long term to the closure state of the door, as when the clothes dryer was manufactured. For that purpose, the functional elements for the latching closure and safety switch are arranged in direct proximity to each other but functionally separated into a component arranged on the door and a component arranged on the casing.

  • Publication number: 20080156623
    Abstract: A safety lockout system deactivates a safety switch to interrupt unintentional electrical current flow or signals controlled by a safety switch which is used on door-like closures. The switch generally comprises two components: one mounted on a moveable closure and the other mounted on an adjacent fixed member, such as a door frame. When the two components are aligned and closely adjacent to each other, as when the closure is in closed position, the switch allows current to flow to an electrically powered device. But when the closure is in its open position, the components are not aligned or closely arranged next to each other so that the lockout system automatically deactivates the switch which then prevents unintentional current flow to the device. The closure and the adjacent fixed member are normally locked together by a slider element which engages a keeper element when the closure is in its closed position.

  • Patent number: 6304177
    Abstract: A switching assembly for use with an exit alarm lock. The switching assembly uses two reed switches which must both be closed for the alarm horn to sound. An arm/disarm switch is operated by a magnet on a pivotable switch link which is operated by a link boss on rotatable deadbolt cams which are operated by the key cylinders. An alarm switch is operated by a magnet in the deadbolt.
