Abstract: A lock-out bracket secures the position of a shaft extending through an actuator, the shaft having a first end and a second end, the first end being operative for controlling a valve, the second end being coupled to a limit switch mounted on a limit switch bracket mounted to the actuator. The lock-out bracket includes a substantially flat base plate and a substantially flat lock-out tab substantially perpendicular to the base plate, the base plate defining an opening configured for matingly fitting over, receiving, and engaging the second end of the shaft. The lock-out tab defines a first hole adapted for alignment with a corresponding second hole defined on the limit switch bracket for facilitating the insertion of a lock shackle through the first hole and the second hole to secure the lock-out bracket relative to the actuator and prevent movement of the shaft and valve coupled to the shaft.

Abstract: The present invention, and inventive system, is a new locking mechanism that prevents entry for doors, or other barriers that can use a deadbolt system, or system comparable to a deadbolt system. The present invention can be installed and works in conjunction with the existing deadbolt assembly to prevent lock picking, a bump key, or a user's own key from being used to open the door. In the present invention, by engaging the arm latch, or arm actuator, of the present invention, over the turn knob on an existing deadbolt, the present invention prevents the free rotation movement of the turn knob, thus not allowing retraction of the deadbolt, and entry through that door or barrier.

Abstract: A lockout device for a handle assembly includes first and second lockout members each including an outward facing base wall and outward extending first and second projections. The first and second projections of the first base member are spaced apart to receive the handle therebetween, and the first and second projections of the second base member are spaced apart to receive the handle latch therebetween. The first and second lockout members are pivotable with respect to each other to a lockout position for engagement of the base walls of the first and second lockout members with facing surfaces of a handle and a handle latch of the handle assembly. When the first and second lockout members are secured between the handle and the handle latch in the lockout position, the first and second lockout members block movement of the handle latch to prevent rotational movement of the handle assembly.

Abstract: Apparatus is simply hung on a deadbolt knob when the deadbolt is in locked position. It prevents the deadbolt knob from rotating enough to retract the deadbolt. This ensures that the door cannot be unlocked from the outside. A passage in an upper end of the apparatus is dimensioned to receive the deadbolt knob. The deadbolt knob is not round. The passage has side walls narrow enough to prevent the deadbolt knob from rotating freely within the passage. As the knob is rotated, the knob engages the side walls of the passage so that the entire apparatus rotates until the lower end of the apparatus engages the door frame. Many passages are provided so that the apparatus may be used with deadbolt knobs that have different locked positions.

Abstract: An electric steering lock for a motorcycle includes a housing, a transmission assembly, a spindle, and a circuit board. The transmission assembly has an actuator, a first gear, a second gear and a sliding block each arranged within the housing in transmissive engagement with each other. The spindle is assembled with the sliding block and acts in the second space. The circuit board is arranged on the bottom of the housing. The primary control chip of the motorcycle controls the circuit board to make the transmission assembly to drive the spindle to move accordingly. The sliding block touches an inner wall of the casing to make it unable to move forwards or backwards any more. The current of the actuator at this time is larger than that in its normal operation. The rotation of the actuator is ceased by the circuit board when a variation in current of the actuator is detected by the circuit board.
