    Abstract: A door opener capable of controlling the door closing speed includes a driving device and a generator mode operating module electrically connected to the driving device. The driving device includes a motor which can be supplied with power to pivot a door from an open position to a closed position. The driving device detects the position of the door by a switch. When pivotal movement of the door is achieved without supplying power to the door, the pivotal movement sets the generator mode operating module to a generator mode or a non-generator mode. In the generator mode, the motor is impeded by the electromagnetic resistance, such that the pivoting speed of the door is reduced. In the non-generator mode, the motor is not impeded by the electromagnetic resistance, such that the pivoting speed of the door is increased.

    Abstract: A furniture drive includes base body to be fixed to a furniture carcass, an actuating arm to be fixed to a movable furniture part, and a locking device for locking the actuating arm to the base body. The locking device includes a locking element movable between a locking position, in which the actuating arm is locked to the base body, and a demounting position, in which the actuating arm can be demounted from the base body. An actuating device can preferably be actuated with a tool, for moving the locking element from the locking position into the demounting position. The furniture drive includes a releasable securing device configured to prevent a movement of the locking element from the locking position into the demounting position upon an actuation of the actuating device.

    Abstract: A kitchen appliance is described. The kitchen appliance has a chamber delimited by a wall arrangement and a lid for sealing the chamber. The lid is attached to the wall arrangement through a hinge mechanism having an arm and a further arm. The arm has a first terminal portion attached to the wall arrangement through a first pivot proximal to a first end portion of the lid and an opposing second terminal portion attached to an intermediate portion of the lid through a second pivot. The further arm has a first further terminal portion attached to an intermediate portion of the arm in between the first terminal portion and the second terminal portion through a third pivot and a second further terminal portion terminating in a sliding arrangement on the lid in between the second pivot and the first end portion of the lid.

    Abstract: A vehicle barrier gate system which is positioned above a roadway through which vehicles pass. Some of the various embodiments of the present disclosure include a gate comprised of an arm and barrier which is adjustable between a raised position in which a vehicle may pass and a lowered position in which a vehicle is prevented from passing. The gate may be movably connected to a ceiling or an overhead support structure positioned above the roadway. Various types of actuators may be utilized to adjust the gate along a linear and/or angular path between the raised and lowered positions. A control unit may be in communication with one or more sensors and/or an authorization system to control the actuator. The gate may include a breakaway mechanism which allows the gate to be manually raised or lowered in the event of actuator failure or a vehicle ramming through the gate.
