Abstract: A pressure bleed-off system. The system includes a fluid bypass line having an inlet and an opposing outlet, wherein the inlet is in fluid communication with a high pressure frac line for a hydraulic fracturing operation. The system also includes a high-pressure transducer located proximate the fluid inlet, a first plug valve residing along the fluid bypass line, and a first electric actuator residing on the first plug valve. The actuator is configured to rotate the first plug valve between close and open positions in response to command signals from a controller. The controller, in turn, sends the command signals in response to control signals delivered by an operator, remotely. Preferably, the command signals are wireless signals sent from outside of the red zone. The system may also include a second plug valve along the bypass line.

Abstract: A package containing sticks of chewing gum is opened at one end to expose the sticks. A cap is placed on the open end of the package and has a frame which surrounds the open end. The frame has two windows each of which is juxtaposed with a group of the chewing gum sticks. A pair of covers for the windows is pivotally mounted on the frame.
