摘要： A window operator has a prime mover for opening and closing of a window, with the prime mover being drivingly connected to a drive output member through an intermediate gear structure. A clutch device in the drive structure senses the torque applied to the drive output member in a window closing operation and a switch operable by the clutch is effective to deenergize the prime mover when the torque applied to the output member reaches a predetermined value. The switch can be adjustably located relative to the clutch whereby the predetermined value at which the motor will be deenergized may be varied in order to obtain a desired tension on a member connected to the closed sash of the window, such as a chain connected to the sash of a skylight window.

摘要： A sliding door is operated automatically by means of a nut and threaded rod which are driven by a reversible motor and constitute a reversible-action motion converter. The motor supply circuit comprises a switchable speed-reduction resistor, a protective resistor in series with the motor and a switchable voltage-limiter which can be connected in shunt across the motor terminals at the end of travel of the door-leaf.

摘要： A gate system and related control systems and methods include a frame assembly and a tracking assembly coupled to the frame assembly. A door is in mechanical communication with the frame assembly. Related methods for operating a gate of a gate system, where the gate is set to manual mode to manually open or close the gate. Additionally, control systems include a fail-safe programmable logic controller (PLC) circuit for controlling the gate for opening and closing a gate that employs redundant fail-safe features. The control system includes a safety PLC circuit having a PLC including a first input terminal and a second input terminal, and a light curtain switch electrically coupled to the first and second input terminals.
