The aim of the invention is to achieve a door closer arrangement (1) where the force needed for opening the door (2) is not so substantial. The invention comprises a door closer (6), a slide rail (7), and an arm (8) that connects the door closer with the slide rail. The arrangement comprises also a second rail (9), which is arranged to form a slide slope for the door closer (6) and the auxiliary spring arrangement.

A door opener includes a first side cover fixed to a mounting seat. A mode switching device is disposed on the first side cover and includes an anti-theft control module. A driving device is operatively connected to a door for moving the door. A control device is electrically connected to the mode switching device and the driving device. The control device includes a control panel for operating the driving device. The mode switching device is switchable to a wake-up mode only when the anti-theft control module is unlocked. The driving device is operable by the control panel only when the mode switching device is in the wake-up mode. An outer cover is coupled to the first side cover and covers an outer side of the driving device and an outer side of the control device. The control panel is exposed via a window of the outer cover to permit operation.

An exemplary armature assembly is configured for use with a door control mounted to one of a door or a doorframe. The door control includes a rotatable pinion, and the armature assembly includes an armature, a shoe, and an elastic component. The armature has a first end and an opposite second end, and the first end includes an opening sized and shaped to receive the pinion at a first interface. The shoe is configured for mounting to the other of the door or the doorframe, and the second end of the armature is pivotally connected to the shoe at a second interface. In certain forms, the elastic component coupled with the armature and configured to absorb mechanical shocks at one of the first interface or the second interface. In certain forms, the elastic component is configured to absorb mechanical shocks along the length of the armature.

A retrofit module configured for use with a door closer having a pinion. The retrofit module generally includes a case, an output shaft, a motor, and a control assembly. The output shaft is rotatably mounted in the case, and is configured for rotational coupling with the pinion. The motor is mounted to the case, and is operable to rotate the output shaft in a door-opening direction. The control assembly is mounted to the case, and is configured to operate the motor to drive the output shaft in the door-opening direction in response to an actuating signal.

The present invention relates to novel lignin-derived compounds and compositions comprising the same and their use as redox flow battery electrolytes. The invention further provides a method for preparing said compounds and compositions as well as a redox flow battery comprising said compounds and compositions. Additionally, an assembly for carrying out the inventive method is provided.

An example door closer includes a casing and a pinion rotatably mounted to the casing. The pinion is operable to rotate through a plurality of movement zones, and the door closer is configured to exert forces on the pinion as the pinion moves through the plurality of movement zones. The door closer further includes a plurality of adjustment mechanisms, each operable to adjust the force exerted on the pinion as the pinion travels through a corresponding movement zone. The casing is provided with indicia that correlate each of the adjustment mechanisms to the corresponding movement zone.

The invention relates to an arrangement of a drive device on a door that can be arranged such that it is pivotable on a housing of an appliance, particularly a cooling and/or refrigerating appliance, in which the drive device designed to pivot the door in relation to the housing is mounted on the door, said drive device comprising: a hinge comprising at least one first hinge part attached to the door and at least one second hinge part which is attached to the housing; at least one drive motor; at least one transmission element which is coupled to the hinge in an at least indirectly articulated manner and can be at least indirectly driven by means of the drive motor; and a coupling device that can switch between at least one coupling state in which the transmission element is coupled to the drive motor and at least one uncoupling state.

A hinge assembly for an aircraft overhead storage bin that includes a housing having a hinge space and a hinge opening defined therein, an arm pivotably connected to the housing within the hinge space, and a dampener. The hinge opening communicates the hinge space with an exterior of the housing. The arm is pivotable between a closed position and an open position and extends through the hinge opening such that the first end of the arm is positioned outside of the housing. The dampener includes first and second ends. The first end is connected to the housing and the second end is connected to the arm. The dampener biases the arm from the closed position to the open position.
