Abstract: An automated system, method and tool for portable friction welding is disclosed for joining a rotatable workpiece to a substrate. A control system is disclosed receiving a start input to cause a motor to rapidly spin the workpiece and initiate a first thrust building cycle acting through an actuator to progressively force the spinning workpiece against the substrate. The materials at this intersection heat and plasticize and the actuator translates toward the substrate until the end of the desired actuator stroke operates to cut the motor off and to initiate and then hold a second axial thrust cycle on the actuator and there through to the interface of the workpiece and substrate. A reset input at the end of a cool off phase releases the thrust in the actuator.

Abstract: Some embodiments include a control bypass system for industrial cold storage facilities. In some embodiments, the control bypass system includes a cloud scheduler and a bypass controller. The cloud scheduler may be located in a remote location. The cloud scheduler may create a power draw prescription for one or more items of cold storage equipment at the industrial cold storage facility. The power draw prescription, for example, can include a desired power draw level for one or more items of cold storage equipment at the industrial cold storage facility and the desired power draw level changes over a period of time. The bypass controller can be located at the industrial cold storage facility and receives the power draw prescription from the cloud scheduler, produces an environmental setpoint for the one or more items of equipment, and outputs the environmental setpoint to a device or system controller.
