摘要： In one or more arrangements, a system is presented for preventing the spread of fire through a conveyor opening in a fire wall. In one or more arrangements, a fire door system is connected to the fire wall and/or conveyor proximate to the conveyor opening. The fire door system includes a door assembly, a door frame assembly, and an actuator. The door frame assembly is connected to the fire wall, covers portions of the opening below the conveyor and between belts of the conveyor, and forms a door opening above the conveyor. The door assembly is configured to move between a closed position, where door assembly covers the door opening, and an open position, where the door assembly at least partially uncovers the door opening. The actuator is configured to cause the door to be moved to the closed position in response to fire.

摘要： A method for automatic control of household-apparatus position, and in particular to fully opening, fully closing and partially opening, etc. French doors, roof windows (also called slanting skylights), French windows, doors, etc. the control method includes generating a command depending on an acquired audio signal, the generated command being able to trigger control by an actuator of a household apparatus, the actuator moving the household apparatus into a position that is dependent on the command. Thus, a number of automation contexts is increased and includes weather-unrelated contexts, for example nuisance-noise-related contexts, and, potentially, also weather-related contexts.

摘要： A damper includes a damper housing, a fluid chamber in the damper housing, a damping fluid in the fluid chamber, a piston displaceable in the fluid chamber, a piston rod connected to the piston, and a volume compensating device in the damper housing. The volume compensating device compensates for a displaceable volume of the damping fluid when the piston rod is immersed into the fluid chamber, and includes a seal to seal the fluid chamber relative to the piston rod and/or relative to an inner wall of the damper housing, a support element to guide the seal, a spring element to reset the seal after a damping stroke at least partially into an initial position. The spring element, the seal, and/or the support element form a common compensating member having an integral one-piece configuration. The compensating member is configured to bear loosely against a cover for closing the damper housing.

摘要： A maintenance system for a gate device includes a controller, at least one temperature sensor, and an evaluation unit. The controller has a motor control unit which actuates a drive apparatus for driving a gate member, and a non-volatile memory which stores gate data. The gate data is retrievable from the non-volatile memory. The at least one temperature sensor is arranged in a region of the drive apparatus. The at least one temperature sensor continuously transmits a detected temperature as further gate data to the non-volatile memory of the controller. The evaluation unit creates a temperature curve for each of the at least one temperature sensor over a preset operating cycle. A comparison of more than one temperature curve allows a conclusion to be drawn of a need for maintenance of the gate device.

摘要： An automatic door operator is disclosed, including a main control circuit, an actuating unit configured to output torque, and a transmission device. The main control circuit controls operation of the actuating unit to drive a movement of a door leaf through the transmission device. The automatic door operator further includes: a DC power supply configured to supply a DC voltage VDD to the main control circuit; and a standby power switching circuit, connected in series between the DC power supply and the main control circuit, and configured to acquire a switching signal and conduct, or cut off after a preset time period Δt has been elapsed, electric current between the DC power supply and the main control circuit according to the switch signal. A method for driving the automatic door operator is also disclosed. The present disclosure realizes the purpose of saving energy and electricity of the automatic door operator, while increasing the lifetime of the main control circuit.

摘要： A door closer and assist system that utilizes a door closer and door assist that aids in reducing the force required to open the door and/or increasing the force for closing the door. The door closer may be installed along with the door assist, or the door assist may be installed to any door closer that is already installed to a door. The door assist may include a track and a drive assembly having a motor assembly, a carriage, and a drive shaft. The motor assembly may have a drive train, a motor, and a controller. One or more sensors may be used to determine when to activate the motor to aid in opening and/or closing the door. The door closer and assist system allows for a door to be closed with a force that is greater than or equal to the force required to open the door.

摘要： Provided is a brake device for braking a rotational movement of a shaft about the longitudinal axis, wherein the shaft is mounted so as to be rotatable about the longitudinal axis in a direction of rotation and in a counter direction which opposes the direction of rotation. Brake devices typically use constant and relatively high braking torques, to ensure a controlled movement of a movement portion, braked by the brake device, in every situation. However, this increases the energy consumption for a movement of the movement portion, and the wear of the brake device. A brake device equipped with a setting device for mutually opposing setting of a braking torque on the shaft during rotation of the shaft in the direction of rotation, and a counter braking torque during rotation of the shaft in the counter direction is provided. Also provided is a method for controlling a brake device.

摘要： An opening/closing direction restriction mechanism for a manual shutter device and an opening/closing direction restriction mechanism for a suspended sliding door device. This opening/closing direction restriction mechanism is provided with: a flange fixedly mounted on a fixed shaft; a bracket which is loosely fitted to the fixed shaft and can be integrally rotated with a winding member; and a two-way clutch which can be switched between a reverse rotation inhibited state in which the revolution of a planetary external gear along a winding direction of the winding member is allowed and the revolution of the planetary external gear along an unwinding direction is inhibited, and a forward rotation inhibited state in which the revolution of the planetary external gear along the winding direction of the winding member is inhibited and the revolution of the planetary external gear along the unwinding direction is allowed.
