A power tong system is used to make up and break out threaded pipe connections. Rotary power tongs are connected to an integral backup tong through an extendable hydraulic cylinder and rod. A brake is secured to the rotary tong to selectively hold the pipe stationary relative to the rotary tong. When rotation of the pipe by the rotary tong ceases, the brake is applied, and the cylinder and rod are actuated to angularly displace the power tongs and the backup tong to apply a torque force to the pipe connection disposed between the power tongs and the backup. A resulting torque force is obtained that is greater than the maximum torque that can be exerted by the rotary tong acting alone. The system may also be deployed to apply and hold precise torque forces on the pipe connections. When used to obtain a makeup torque below the maximum rated rotary tong output, the rotary tong is regulated to limit its torque output. When the limited torque is reached, the brake is applied and the cylinder and rod are actuated to apply a smooth, closely controlled increase in torque to the connection. The final torque level may be held constant for a desired length of time. In both the high and low torque applications, the brake prevents the rotary tong from being turned backwardly by the increased torque force applied by actuation of the rod and cylinder assembly. Operation of the system may be manually or automatically controlled.

A system and method for automatic ways of prioritizing the presentation of windows on a graphical user interface (GUI) and for prioritizing and accessing information stored in cache that is used by a web browser. The viewing (tiling) priority of windows, the size of windows, and the position of windows on a GUI are automatically determined from the following criteria: the time the window was first opened, the time the window was last opened, the length of time the window was visible on the screen, the percentage visibility of the window, the amount of scrolling the window has undergone, the content of the window, the time of day, the number of window accesses, and/or some mathematical function of these criteria. Additionally, these same criteria are applied to cached information associated with web pages so that more “relevant” cached web pages are automatically stored in cache for longer periods of time before being discarded in a finite sized cache. The cached information is more quickly accessible by hitting a “back-like” button that shows more relevant (i.e. higher priority) information before less relevant information.
